可选地，在触发进行对应候选小区TA的更新时，该方法包括：向终端设备发送PDCCH指令，PDCCH指令包括随机接入资源指示信息；随机接入资源指示信息用于指示终端设备通过CFRA请求从第二网络设备获取对应候选小区当前TA；接收终端设备发送的第四指示信息，第四指示信息用于指示已更新对应候选小区的TA或更新后的TA值。Optionally, when triggering the update of the corresponding candidate cell TA, the method includes: sending a PDCCH instruction to the terminal equipment, where the PDCCH instruction includes random access resource indication information; the random access resource indication information is used to instruct the terminal equipment to request through CFRA Obtain the current TA of the corresponding candidate cell from the second network device; receive fourth indication information sent by the terminal device, where the fourth indication information is used to indicate that the TA of the corresponding candidate cell or the updated TA value has been updated.
或者，向终端设备发送测量指令，测量指令用于指示终端设备执行候选小区的当前TA测量过程；接收终端设备发送的第四指示信息，第四指示信息用于指示已更新对应候选小区的TA或更新后的TA值。Or, send a measurement instruction to the terminal equipment, the measurement instruction is used to instruct the terminal equipment to perform the current TA measurement process of the candidate cell; receive fourth indication information sent by the terminal equipment, the fourth indication information is used to indicate that the TA of the corresponding candidate cell has been updated or The updated TA value.
也就是说，存在两种方法使得第一网络设备触发进行对应候选小区TA的更新。第一种，第一网络设备向终端设备发送触发CFRA请求的PDCCH指令，以使得终端设备根据PDCCH指令获取候选小区的当前TA，并使得终端设备按照该当前TA进行对应候选小区TA的更新，由此使得第一网络设备能够在终端设备得到第二网络设备返回的当前TA之后顺利获取候选小区的最新TA，相较于在终端设备发送新的指令得到当前TA之后获取候选小区的最新TA，节省了传输资源，并提高了第一网络设备获取候选小区的最新TA的及时性。第二种向终端设备发送测量指令，以使得终端设备自行测量当前TA，并使得终端设备按照该当前TA进行对应候选小区TA的更新，由此使得第一网络设备能够在终端设备自行得到当前TA之后获取候选小区的最新TA，提高第一网络设备获知候选小区最新TA的效率。That is to say, there are two methods for causing the first network device to trigger the update of the corresponding candidate cell TA. First, the first network device sends a PDCCH instruction that triggers a CFRA request to the terminal device, so that the terminal device obtains the current TA of the candidate cell according to the PDCCH instruction, and causes the terminal device to update the TA of the corresponding candidate cell according to the current TA. This enables the first network device to successfully obtain the latest TA of the candidate cell after the terminal device obtains the current TA returned by the second network device. Compared with obtaining the latest TA of the candidate cell after the terminal device sends a new instruction to obtain the current TA, it saves Transmission resources are increased, and the timeliness in which the first network device obtains the latest TA of the candidate cell is improved. The second method is to send a measurement instruction to the terminal device, so that the terminal device can measure the current TA by itself, and make the terminal device update the corresponding candidate cell TA according to the current TA, so that the first network device can obtain the current TA by the terminal device itself. Then, the latest TA of the candidate cell is obtained, thereby improving the efficiency of the first network device in learning the latest TA of the candidate cell.
在此基础上，本申请提供了两种触发对候选小区TA的更新的方式，提高由第一网络设备管理时更新候选小区TA的灵活性。On this basis, this application provides two ways of triggering the update of the candidate cell TA to improve the flexibility of updating the candidate cell TA when managed by the first network device.
可选地，该方法还包括：若存在有效的目标小区TA，则在MAC CE信令中携带目标小区TA值；向终端设备发送MAC CE信令；MAC CE信令用于指示终端设备向目标小区对应的第二网络设备发送切换指示；若不存在有效的目标小区TA，则在MAC CE信令中不携带目标小区TA值；向终端设备发送MAC CE信令；MAC CE信令用于指示终端设备与目标小区对应的第二网络设备执行上行同步过程。Optionally, the method also includes: if there is a valid target cell TA, carrying the target cell TA value in the MAC CE signaling; sending MAC CE signaling to the terminal device; MAC CE signaling is used to instruct the terminal device to send the target cell TA value to the target cell. The second network device corresponding to the cell sends a handover indication; if there is no valid target cell TA, the target cell TA value is not carried in the MAC CE signaling; MAC CE signaling is sent to the terminal device; MAC CE signaling is used for instructions The terminal device performs an uplink synchronization process with the second network device corresponding to the target cell.
也就是说，为了使得终端设备执行对目标小区的切换，第一网络设备可以根据目标小区TA的有效性向终端设备发送MAC CE信令，即在确定目标小区TA有效时发送包括目标小区TA的MAC CE信令，在确定目标小区TA无效时发送不包括目标小区TA的MAC CE信令。以使得终端设备可以根据MAC CE信令在目标小区TA有效时进行切换，在无效时与目标小区对应的第二网络设备执行包括CFRA的上行同步过程。由此实现切换，提高切换的成功率。That is to say, in order for the terminal device to perform handover to the target cell, the first network device can send MAC CE signaling to the terminal device according to the validity of the target cell TA, that is, when it is determined that the target cell TA is valid, it sends the MAC including the target cell TA. CE signaling: when it is determined that the target cell TA is invalid, MAC CE signaling excluding the target cell TA is sent. This allows the terminal device to perform handover when the target cell TA is valid according to the MAC CE signaling, and when it is invalid, the second network device corresponding to the target cell performs an uplink synchronization process including CFRA. This implements handover and improves the success rate of handover.
第三方面，提供了一种定时提前量管理方法，该方法可以由第二网络设备执行，或者，也可以由配置于第二网络设备中的部件（例如芯片或者电路）执行。本申请对此不作限定。A third aspect provides a timing advance management method, which can be executed by a second network device, or can also be executed by a component (such as a chip or circuit) configured in the second network device. This application does not limit this.
例如，该方法包括：若对候选小区的TA进行有效性管理的设备为第二网络设备，则接收终端设备发送的第三指示信息，第三指示信息用于指示已获取对应候选小区的TA或TA值；根据第三指示信息对对应候选小区的TA进行有效性管理。For example, the method includes: if the device that performs validity management of the TA of the candidate cell is a second network device, receiving third indication information sent by the terminal device, and the third indication information is used to indicate that the TA of the corresponding candidate cell has been obtained or TA value; perform validity management on the TA corresponding to the candidate cell according to the third indication information.
也就是说，当终端设备在根据第一指示信息确定由第二网络设备管理时，通过向第二网络设备发送第三指示信息，就可使得第二网络设备对候选小区的TA进行有效性管理。由此实现多个设备均可进行定时提前量进行管理，提高管理的灵活性。That is to say, when the terminal device determines that it is managed by the second network device based on the first indication information, by sending the third indication information to the second network device, the second network device can perform validity management on the TA of the candidate cell. . This enables multiple devices to be managed in advance, improving management flexibility.
结合第三方面，在第三方面的某些实现方式中，该第三网络设备是候选小区所属的网络设备。即，该第二网络设备是候选网络设备。Combined with the third aspect, in some implementations of the third aspect, the third network device is a network device to which the candidate cell belongs. That is, the second network device is a candidate network device.
可选地，该方法还包括：接收终端设备发送的CFRA请求，CFRA请求用于指示第二网络设备获取对应候选小区的TA，CFRA请求是第一网络设备向终端发送第二指示信息后终端发送至第二网络设备的，第二指示信息用于指示无竞争随机接入CFRA过程是否包括随机接入响应RAR；若第二指示信息指示CFRA过程包括RAR，则向终端设备发送RAR，RAR包括对应候选小区的TA；Optionally, the method further includes: receiving a CFRA request sent by the terminal device. The CFRA request is used to instruct the second network device to obtain the TA of the corresponding candidate cell. The CFRA request is sent by the terminal after the first network device sends the second indication information to the terminal. To the second network device, the second indication information is used to indicate whether the contention-free random access CFRA process includes a random access response RAR; if the second indication information indicates that the CFRA process includes a RAR, the RAR is sent to the terminal device, and the RAR includes the corresponding TA of the candidate cell;
或者；or;
接收终端设备发送的包括RAR的CFRA请求，包括RAR的CFRA请求用于指示CFRA过程包括RAR；向终端设备发送RAR，RAR包括对应候选小区的TA。Receive the CFRA request including the RAR sent by the terminal device, and the CFRA request including the RAR is used to indicate that the CFRA process includes the RAR; send the RAR to the terminal device, and the RAR includes the TA corresponding to the candidate cell.
也就是说，存在两种情况使得第二网络设备向终端发送TA。第一种，第二网络设备接收终端设备发送的CFRA请求，在判断该CFRA请求包括RAR之后向终端设备发送带TA的RAR。第二种，第二网络设备直接接收终端设备发送的包括RAR的CFRA请求，并向终端设备发送带TA的RAR。由此增加终端设备获取TA的灵活性。That is to say, there are two situations that cause the second network device to send TA to the terminal. First, the second network device receives the CFRA request sent by the terminal device, determines that the CFRA request includes RAR, and then sends the RAR with TA to the terminal device. Second, the second network device directly receives the CFRA request including RAR sent by the terminal device, and sends the RAR with TA to the terminal device. This increases the flexibility of the terminal device to obtain TA.
结合第三方面，在第三方面的某些实现方式中，第二指示信息的承载方式可以为：第二指示信息承载在物理下行控制信道调度PDCCH指令中；或者，第二指示信息承载在无限资源控制RRC重配置信令消息中。Combined with the third aspect, in some implementations of the third aspect, the second indication information may be carried in the following manner: the second indication information is carried in the physical downlink control channel scheduling PDCCH instruction; or, the second indication information is carried in the wireless Resource control RRC reconfiguration signaling message.
可选地，该方法包括：获取对应候选小区的第一配置信息和第二配置信息。Optionally, the method includes: obtaining first configuration information and second configuration information corresponding to the candidate cell.
也就是说，在对候选小区的TA进行有效性管理之前，第二网络设备还需要获取到具有多种搭配的第一配置信息和第二配置信息，以根据多种搭配的第一配置信息和第二配置信息对候选小区的TA进行有效性管理。由此提高第二网络设备管理的灵活性。That is to say, before performing validity management on the TA of the candidate cell, the second network device also needs to obtain the first configuration information and the second configuration information with multiple collocations, so as to use the first configuration information and the second configuration information with multiple collocations according to the multiple collocations. The second configuration information performs validity management on the TA of the candidate cell. This improves the flexibility of management of the second network device.
结合第三方面，在第三方面的某些实现方式中，第一配置信息包括候选小区的TA公共有效时长及超过公共有效时长TA失效的信息或者对应候选小区的TA私有有效时长及超过私有有效时长对应TA失效的信息。且，第二配置信息为候选小区的TA公共更新时长阈值或对应候选小区的TA私有更新时长阈值。Combined with the third aspect, in some implementations of the third aspect, the first configuration information includes the TA public validity period of the candidate cell and information on TA failure exceeding the public validity period, or the TA private validity period corresponding to the candidate cell and exceeding the private validity period. The duration corresponds to the information of TA failure. Moreover, the second configuration information is the TA public update duration threshold of the candidate cell or the TA private update duration threshold of the corresponding candidate cell.
其中，候选小区的TA公共更新时长阈值为小于公共有效时长的数值或小于剩余公共有效时长的数值；剩余公共有效时长为启动TA计时器时公共有效时长与计时时间的差值；对应候选小区的TA私有更新时长阈值为小于私有有效时长的数值或小于剩余私有有效时长的数值，剩余私有有效时长为启动TA计时器时私有有效时长与计时时间的差值。Among them, the TA public update duration threshold of the candidate cell is a value smaller than the public valid duration or a value smaller than the remaining public valid duration; the remaining public valid duration is the difference between the public valid duration and the timing time when the TA timer is started; the corresponding candidate cell The TA private update duration threshold is a value smaller than the private valid duration or a value smaller than the remaining private valid duration. The remaining private valid duration is the difference between the private valid duration and the timing time when the TA timer is started.
可选地，在根据第三指示信息对候选小区的TA进行有效性管理时，启动TA计时器进行计时，若计时时间达到TA公共更新时长阈值或TA私有更新时长阈值，则触发进行对应候选小区TA的更新。Optionally, when performing validity management on the TA of the candidate cell according to the third instruction information, start the TA timer for timing. If the timing time reaches the TA public update duration threshold or the TA private update duration threshold, trigger the corresponding candidate cell. TA's update.
也就是说，第二网络设备通过启动对应候选小区的TA计时器，即可在计时时间达到TA公共更新时长阈值或TA私有更新时长阈值时触发进行对应候选小区TA的更新，无需在候选小区TA将要失效时触发候选小区TA的更新，提高第二网络设备更新候选小区TA的及时性。That is to say, by starting the TA timer corresponding to the candidate cell, the second network device can trigger the update of the TA corresponding to the candidate cell when the timer reaches the TA public update duration threshold or the TA private update duration threshold. There is no need to update the TA in the candidate cell. The update of the candidate cell TA is triggered when it is about to expire, thereby improving the timeliness of the second network device updating the candidate cell TA.
可选地，在触发进行对应候选小区TA的更新时，该方法包括：向第一网络设备发送第一消息，第一消息用于指示第一网络设备向终端设备发送PDCCH指令；接收终端设备发送的CFRA请求，CFRA请求用于指示第二网络设备获取对应候选小区的当前TA；向终端设备发送CFRA响应，CFRA响应包括对应候选小区的当前TA；接收终端设备发送的第四指示信息，第四指示信息用于指示已更新对应候选小区的TA或更新后的TA值；Optionally, when an update of the corresponding candidate cell TA is triggered, the method includes: sending a first message to the first network device, the first message being used to instruct the first network device to send a PDCCH instruction to the terminal device; receiving the message sent by the terminal device. CFRA request, the CFRA request is used to instruct the second network device to obtain the current TA corresponding to the candidate cell; send a CFRA response to the terminal device, the CFRA response includes the current TA corresponding to the candidate cell; receive the fourth indication information sent by the terminal device, and the fourth The indication information is used to indicate that the TA of the corresponding candidate cell or the updated TA value has been updated;

First, the second network device instructs the first network device to send a PDCCH instruction, so that the first network device sends the PDCCH instruction to the terminal according to the instruction, and causes the terminal device to obtain the current TA of the candidate cell according to the PDCCH instruction, so that the terminal device The corresponding candidate cell TA is updated according to the current TA, so that the terminal device can send the update result to the second network device, thereby enabling the second network device to successfully obtain the latest TA of the candidate cell after the terminal device obtains the returned current TA. , compared with obtaining the latest TA of the candidate cell after the terminal device sends a new instruction to obtain the current TA, this saves transmission resources and improves the timeliness in which the second network device obtains the latest TA of the candidate cell. Second, the second network device instructs the first network device to send a measurement instruction, so that the first network device sends a measurement instruction to the terminal device according to the instruction, and the terminal device measures the current TA after measuring the current TA by itself. The update of the candidate cell TA enables the terminal device to send the update result to the second network device. This enables the second network device to obtain the latest TA of the candidate cell after the terminal device obtains the current TA by itself, thereby improving the efficiency of the second network device in obtaining the latest TA of the candidate cell.

The fourth message includes information on whether the target cell TA is valid; the information on whether the target cell TA is valid is used to indicate whether the MAC CE signaling sent by the first network device to the terminal device includes the target cell TA value.
也就是说，为了使得终端设备执行对目标小区的切换，第二网络设备通过接收第一网络设备发送的确认目标小区TA是否有效的消息，即可根据该消息向第一网络设备发送目标小区TA是否有效的结果。以使得第一网络设备根据目标小区TA的有效性向终端设备发送MAC CE信令，并使得终端设备根据MAC CE信令在目标小区TA有效时进行切换，在无效时与目标小区对应的第二网络设备执行包括CFRA的上行同步过程。由此实现切换，提高切换的成功率。That is to say, in order for the terminal device to perform handover to the target cell, the second network device can send the target cell TA to the first network device according to the message by receiving a message sent by the first network device to confirm whether the target cell TA is valid. Is the result valid? So that the first network device sends MAC CE signaling to the terminal device according to the validity of the target cell TA, and the terminal device performs handover according to the MAC CE signaling when the target cell TA is valid, and when it is invalid, the second network corresponding to the target cell The device performs the uplink synchronization process including CFRA.

为便于理解本申请实施例，首先对本申请中涉及到的术语作简单说明。In order to facilitate understanding of the embodiments of this application, the terms involved in this application are first briefly explained.
1、小区：小区是高层从资源管理或移动性管理或服务单元的角度来描述的。每个网络设备的覆盖范围可以被划分为一个或多个小区，且每个小区可以对应一个或多个频点，或者说，每个小区可以看成是一个或多个频点的覆盖范围所形成的区域。1. Cell: The cell is described by the higher layer from the perspective of resource management or mobility management or service unit. The coverage of each network device can be divided into one or more cells, and each cell can correspond to one or more frequency points. In other words, each cell can be regarded as the coverage of one or more frequency points. formed area.
需要说明的是，小区可以是网络设备的无线网络的覆盖范围内的区域。在本申请实施例中，不同的小区可以对应相同或者不同的网络设备。例如，小区#1所属的网络设备和小区#2所属的网络设备可以是不同的网络设备，如，基站。也就是说，小区#1和小区#2可以由不同的基站来管理。或者，又例如，管理小区#1的网络设备和管理小区#2的网络设备也可以是同一基站的不同的射频处理单元，例如，射频拉远单元（radio remote unit，RRU），也就是说，小区#1和小区#2可以由同一基站管理，具有相同的基带处理单元和中频处理单元，但具有不同的射频处理单元。或者，再例如，小区#1所属的网络设备和小区#2所属的网络设备可以是同一个网络设备，如，基站。也就是说，小区#1和小区#2可以由相同的基站来管理，这种情况下，可以称为小区#1和小区#2共站。本申请对此不做特别限定。It should be noted that a cell may be an area within the coverage of the wireless network of the network device. In this embodiment of the present application, different cells may correspond to the same or different network devices. For example, the network equipment to which cell #1 belongs and the network equipment to which cell #2 belongs may be different network equipment, such as a base station. That is, cell #1 and cell #2 may be managed by different base stations. Or, for another example, the network device that manages cell #1 and the network device that manages cell #2 can also be different radio frequency processing units of the same base station, such as a radio remote unit (RRU), that is, Cell #1 and Cell #2 may be managed by the same base station, have the same baseband processing unit and IF processing unit, but have different radio frequency processing units. Or, for another example, the network device to which cell #1 belongs and the network device to which cell #2 belongs can be the same network device, such as a base station. That is to say, cell #1 and cell #2 can be managed by the same base station. In this case, it can be said that cell #1 and cell #2 are co-located. This application does not specifically limit this.
在一些可能的部署中，基站可以包括CU和DU。在这种部署下，小区#1和小区#2可以由同一个CU和同一个DU管理，即，共CU且共DU；小区#1和小区#2可以由同一个CU和不同的DU管理，即，共CU但不共DU；小区#1和小区#2也可以由不同的CU和不同的DU管理，即，不共CU且不共DU。In some possible deployments, base stations may include CUs and DUs. Under this deployment, cell #1 and cell #2 can be managed by the same CU and the same DU, that is, common CU and common DU; cell #1 and cell #2 can be managed by the same CU and different DU, That is, they share a CU but not a DU; cell #1 and cell #2 can also be managed by different CUs and different DUs, that is, they do not share a CU and do not share a DU.
2、切换：在无线通信系统中，当终端设备从一个小区向另一个小区移动/靠近时，为了保持终端设备的通信不中断，需要进行切换。在本申请实施例中，源小区表示切换前为终端设备提供服务的小区，候选小区表示切换后可能为终端设备提供服务的潜在小区，目标小区表示候选小区中最终为终端设备提供服务的小区。2. Handover: In the wireless communication system, when the terminal device moves/approaches from one cell to another cell, handover is required in order to keep the communication of the terminal device uninterrupted. In the embodiment of this application, the source cell represents the cell that provides services to the terminal equipment before handover, the candidate cell represents the potential cell that may provide services to the terminal equipment after handover, and the target cell represents the cell among the candidate cells that ultimately provides services to the terminal equipment.
候选小区的相关信息（如候选小区的物理小区标识、频率信息、切换至候选小区所需的随机接入资源信息等），可以通过切换消息来指示，该切换消息是源小区所属的网络设备（即源网络设备）通过RRC重配置信令消息向终端设备发送的。The relevant information of the candidate cell (such as the physical cell identity of the candidate cell, frequency information, random access resource information required to switch to the candidate cell, etc.) can be indicated through a handover message. The handover message is the network device to which the source cell belongs ( That is, the source network device) is sent to the terminal device through the RRC reconfiguration signaling message.
切换可以是站内切换或站间切换。站内切换，可以指源小区与候选小区属于同一个网络设备（如基站），其中，源小区、候选小区可以是同一个小区或者不同的小区；站间切换，指源小区与候选小区属于不同的网络设备（如基站）。本申请对此不做限定。Handover can be intra-site handover or inter-site handover. Intra-site handover can mean that the source cell and the candidate cell belong to the same network device (such as a base station), in which the source cell and the candidate cell can be the same cell or different cells; inter-site handover means that the source cell and the candidate cell belong to different Network equipment (such as base stations). This application does not limit this.
应理解，小区即为网络设备的覆盖区域，源小区对应源网络设备（例如源基站），候选小区对应候选网络设备（例如候选基站）。It should be understood that the cell is the coverage area of the network device, the source cell corresponds to the source network device (for example, the source base station), and the candidate cell corresponds to the candidate network device (for example, the candidate base station).
还应理解，源小区和候选小区可以属于同一网络设备，或者说，源小区和候选小区可以是共站的。此时，对于某一终端设备，候选小区对应的TA可以等于源小区对应的TA。候选小区也可以为小小区，此时，对于某一终端设备，候选小区的定时提前量TA可以为0。It should also be understood that the source cell and the candidate cell may belong to the same network device, or that the source cell and the candidate cell may be co-located. At this time, for a certain terminal device, the TA corresponding to the candidate cell may be equal to the TA corresponding to the source cell. The candidate cell may also be a small cell. In this case, for a certain terminal device, the timing advance TA of the candidate cell may be 0.
传统的切换流程中，终端设备的移动性管理是由网络设备控制的。即，网络设备通过发送切换消息指示终端设备切换到哪个小区以及如何进行切换。例如，源网络设备向终端设备发送切换消息以控制终端设备从源小区切换到目标小区。该切换消息可以是RRC消息。In the traditional handover process, the mobility management of the terminal device is controlled by the network device. That is, the network device instructs the terminal device to which cell to switch to and how to perform the switching by sending a switching message. For example, the source network device sends a handover message to the terminal device to control the terminal device to switch from the source cell to the target cell. The handover message may be an RRC message.
3、LTM切换流程：即Layer1/2 triggered mobility切换流程，在终端设备上报测量报告的基础上由基站进行决策的切换。图1a是示例性地示出了LTM切换流程中终端设备与各网络设备之间的信令交互图，结合图1a，下面对LTM切换流程进行简单说明。LTM切换流程具体可以包括下文的S101至S110。3. LTM handover process: that is, Layer1/2 triggered mobility handover process. The base station makes decision-making handover based on the measurement report reported by the terminal device. Figure 1a is an exemplary diagram showing the signaling interaction between the terminal device and each network device in the LTM handover process. With reference to Figure 1a, the LTM handover process will be briefly described below. The LTM handover process may specifically include S101 to S110 below.
S101、处于连接态的终端设备向源小区网络设备上报测量结果。S101. The terminal device in the connected state reports the measurement results to the source cell network device.
S102、源小区网络设备根据终端对LTM的支持能力在确定执行LTM后向候选小区网络设备发送LTM切换请求，该候选小区包括目标小区和潜在目标小区，该候选小区为一个或多个。S102. The source cell network device sends an LTM handover request to the candidate cell network device after determining to perform LTM based on the terminal's ability to support LTM. The candidate cell includes one or more target cells and potential target cells.
S103、候选小区网络设备向源小区网络设备发送LTM切换响应，该LTM切换响应包括候选小区配置信息。S103. The candidate cell network device sends an LTM handover response to the source cell network device, where the LTM handover response includes the candidate cell configuration information.
S104、源小区网络设备将候选小区配置信息通过RRC重配置消息发送给终端设备。S104. The source cell network device sends the candidate cell configuration information to the terminal device through an RRC reconfiguration message.
S105、终端设备根据候选小区配置信息执行对各个候选小区的下行同步。S105. The terminal device performs downlink synchronization of each candidate cell according to the candidate cell configuration information.
S106、终端设备根据候选小区配置信息执行对各个候选小区的上行同步。S106. The terminal device performs uplink synchronization of each candidate cell according to the candidate cell configuration information.
在执行上行同步时，涉及到对上行同步时候选小区的定时提前量TA的管理，一种方式是，由源小区网络设备通过PDCCH order触发非竞争随机接入流程来获取候选小区的定时提前量TA，并管理候选小区的定时提前量TA的有效性。When performing uplink synchronization, it involves the management of the timing advance TA of the selected cell during uplink synchronization. One way is for the source cell network device to trigger the non-contention random access process through PDCCH order to obtain the timing advance of the candidate cell. TA, and manages the validity of the timing advance TA of the candidate cell.
S107、终端设备执行针对源小区以及候选小区的L1测量并将测量结果上报至源小区网络设备。S107. The terminal device performs L1 measurement on the source cell and the candidate cell and reports the measurement results to the source cell network device.

4、定时提前量：即TA，在执行上行同步时终端设备发送上行数据的时间相对于下行所需提前的时间。终端设备在获取TA时，一般是通过以下两种方式进行的。其一为由源小区网络设备通过PDCCH order向终端设备提供CFRA资源，使得终端设备根据CFRA资源触发CFRA请求以获得TA。其二是由源小区网络设备指示终端自行测量TA，使得终端设备根据指示自行测量。4. Timing advance: TA, when performing uplink synchronization, the time when the terminal device sends uplink data is advanced relative to the time required for downlink. When the terminal device obtains TA, it generally performs the following two methods. One is that the source cell network equipment provides CFRA resources to the terminal equipment through the PDCCH order, so that the terminal equipment triggers a CFRA request based on the CFRA resources to obtain the TA. The second method is for the source cell network equipment to instruct the terminal to measure TA by itself, so that the terminal equipment can measure itself according to the instruction.
应理解，上述两种终端设备获取TA的方式仅为举例，不应对本申请构成任何限定。It should be understood that the above two ways for terminal devices to obtain TA are only examples and should not constitute any limitation on this application.
5、TA有效性管理：在执行切换时应确保终端设备所获取的TA有效方可直接向目标小区发起切换，该确保终端设备所获取的TA有效的过程即为TA有效性管理。5. TA validity management: When performing handover, it is necessary to ensure that the TA obtained by the terminal device is valid before directly initiating a handover to the target cell. The process of ensuring that the TA obtained by the terminal device is valid is TA validity management.
6、非竞争随机接入流程：即CFRA，终端设备开始向尝试接入的网络设备发送随机接入前导码索引（preamble index），至终端设备与网络设备间建立起连接的这段过程。具体地，终端设备通过PRACH向网络设备发送随机接入前导码索引（或者称随机接入前导序列）。在非竞争的随机接入流程中，该随机接入前导码索引是网络设备提前分配给终端设备的。换句话说，该随机接入前导码索引是专用的。网络设备向终端设备发送随机接入响应。该随机接入响应中可以包含响应的TA。6. Non-contention random access process: CFRA, the process from which the terminal device starts sending a random access preamble index (preamble index) to the network device trying to access, to when a connection is established between the terminal device and the network device. Specifically, the terminal device sends a random access preamble index (or random access preamble sequence) to the network device through PRACH. In the non-contention random access process, the random access preamble index is assigned by the network device to the terminal device in advance. In other words, the random access preamble index is specific. The network device sends a random access response to the terminal device. The random access response may include the response TA.
7、包括RAR的CFRA：终端设备向网络设备发起CFRA时同时发起获取RAR的请求的过程。具体地，终端设备基于获取RAR的需求连同CFRA请求发送至网络设备。网络设备将包括TA的RAR协议发送至终端设备。7. CFRA including RAR: When the terminal device initiates CFRA to the network device, it also initiates a request to obtain RAR. Specifically, the terminal device sends a CFRA request to the network device based on the need to obtain the RAR. The network device sends the RAR protocol including TA to the terminal device.

The execution order of each step should be determined by its function and internal logic.
终端设备在网络连接状态下可能会由于当前网络不佳触发小区变更，这就涉及到终端设备与候选小区的上行同步过程。那么为了确保变更过程中信息能够同步传输，终端设备会被触发执行对候选小区的定时提前量TA的获取，并需要对已获取到的候选小区的TA进行有效性管理。对此，一种对候选小区的TA进行有效性管理的方式是由网络设备直接进行管理，这使得对候选小区的TA进行有效性管理的灵活性较差。对此，本申请实施例提供一种定时提前量的管理方法，其主要发明思路如下：When the terminal device is connected to the network, it may trigger a cell change due to poor current network conditions, which involves the uplink synchronization process between the terminal device and the candidate cell. In order to ensure that information can be transmitted synchronously during the change process, the terminal device will be triggered to obtain the timing advance TA of the candidate cell, and needs to perform validity management on the obtained TA of the candidate cell. In this regard, one way to manage the validity of the TA of the candidate cell is to directly manage the TA of the candidate cell by the network device, which makes the flexibility of validity management of the TA of the candidate cell less flexible. In this regard, embodiments of the present application provide a timing advance management method, and its main inventive ideas are as follows:
为了提高对候选小区的TA进行有效性管理的灵活性，不是仅由网络设备对候选小区的TA进行有效性管理，而是在此基础上增加了终端设备对候选小区的TA进行有效性管理的实现方式，使得当需要对候选小区的TA进行有效性管理时，终端设备可以根据所指示的具体设备，在确定指示终端设备时直接对候选小区的TA进行有效性管理，在确定指示源小区网络设备时将获取候选小区的TA的结果告知源小区网络设备，由源小区网络设备对候选小区的TA进行有效性管理，在确定指示候选小区网络设备时将获取候选小区的TA的结果告知候选小区网络设备，由候选小区网络设备对候选小区的TA进行有效性管理。由此实现终端设备及网络设备均可对定时提前量进行管理，提高定时提前量管理的灵活性。In order to improve the flexibility of effectiveness management of TAs of candidate cells, instead of only network equipment performing effectiveness management of TAs of candidate cells, on this basis, terminal equipment is added to perform effectiveness management of TAs of candidate cells. The implementation is such that when it is necessary to perform validity management on the TA of the candidate cell, the terminal device can directly perform validity management on the TA of the candidate cell according to the specific indicated device when determining the indication terminal device, and determine the indication source cell network When the device is configured, the source cell network device will be notified of the result of obtaining the TA of the candidate cell. The source cell network device will perform validity management of the TA of the candidate cell. When the candidate cell network device is determined to indicate the candidate cell, the result of obtaining the TA of the candidate cell will be notified to the candidate cell. Network equipment: The network equipment of the candidate cell performs validity management on the TA of the candidate cell. In this way, both terminal equipment and network equipment can manage the timing advance, thereby improving the flexibility of timing advance management.

As shown in Figure 2, the method 200 may include steps 201 to 204. Each step in the method 200 is described in detail below.
在步骤201中，第一网络设备向终端设备发送第一指示信息，该第一指示信息用于指示对候选小区的定时提前量TA进行有效性管理的设备，该对候选小区的定时提前量TA进行有效性管理的设备为终端设备或第一网络设备或第二网络设备，该候选小区为一个或多个。In step 201, the first network device sends first indication information to the terminal device. The first indication information is used to instruct the device to perform validity management of the timing advance amount TA of the candidate cell. The device that performs validity management is a terminal device or a first network device or a second network device, and there are one or more candidate cells.
应理解，对候选小区的定时提前量TA进行有效性管理的具体应用场景为当前正在执行小区切换，这就涉及到三种设备，即终端设备、表征源小区网络设备的第一网络设备以及表征候选小区网络设备的第二网络设备。因此，可在第一指示信息中选择性地指示对候选小区的定时提前量TA进行有效性管理的设备，下面对第一指示信息中的具体指示方式进行说明。It should be understood that the specific application scenario for managing the validity of the timing advance TA of the candidate cell is that cell handover is currently being performed, which involves three devices, namely the terminal device, the first network device representing the source cell network device, and the characterizing device. The second network device of the candidate cell network device. Therefore, the device for managing the validity of the timing advance TA of the candidate cell can be selectively indicated in the first indication information. The specific indication method in the first indication information will be described below.
在一种示例中，第一指示信息中可以包括对候选小区的定时提前量TA进行有效性管理的设备对应的设备信息。当第一指示信息中包括终端设备对应的设备信息时，则指示由终端设备对候选小区的定时提前量TA进行有效性管理。同理，当第一指示信息中包括第一网络设备对应的设备信息时，则指示由第一网络设备对候选小区的定时提前量TA进行有效性管理。同理，当第一指示信息中包括第二网络设备对应的设备信息时，则指示由第二网络设备对候选小区的定时提前量TA进行有效性管理。In one example, the first indication information may include device information corresponding to a device that performs validity management on the timing advance TA of the candidate cell. When the first indication information includes device information corresponding to the terminal device, it indicates that the terminal device performs validity management on the timing advance TA of the candidate cell. Similarly, when the first indication information includes device information corresponding to the first network device, it indicates that the first network device performs validity management on the timing advance TA of the candidate cell. Similarly, when the first indication information includes device information corresponding to the second network device, it indicates that the second network device performs validity management on the timing advance TA of the candidate cell.
在另一种示例中，第一指示信息中可以包括不对候选小区的定时提前量TA进行有效性管理的设备对应的设备信息。当第一指示信息中包括第一网络设备以及第二网络设备对应的设备信息时，则指示由终端设备对候选小区的定时提前量TA进行有效性管理。同理，当第一指示信息中包括终端设备以及第二网络设备对应的设备信息时，则指示由第一网络设备对候选小区的定时提前量TA进行有效性管理。同理，当第一指示信息中包括终端设备以及第一网络设备对应的设备信息时，则指示由第二网络设备对候选小区的定时提前量TA进行有效性管理。In another example, the first indication information may include device information corresponding to a device that does not perform validity management of the timing advance TA of the candidate cell. When the first indication information includes device information corresponding to the first network device and the second network device, it indicates that the terminal device performs validity management on the timing advance TA of the candidate cell. Similarly, when the first indication information includes device information corresponding to the terminal device and the second network device, it indicates that the first network device performs validity management on the timing advance TA of the candidate cell. Similarly, when the first indication information includes device information corresponding to the terminal device and the first network device, it indicates that the second network device performs validity management on the timing advance TA of the candidate cell.
那么为了进一步节省传输资源，第一指示信息中还可以将设备信息替换为对候选小区的定时提前量TA进行有效性管理的设备对应的标识或编号，本申请对此不做限定。Then, in order to further save transmission resources, the device information in the first indication information can also be replaced with the identification or number corresponding to the device that performs validity management of the timing advance TA of the candidate cell. This application does not limit this.
在还一种示例中，第一指示信息中可以包括固定顺序的三个预定义的字段，基于预定义的字段的取值确定对候选小区的定时提前量TA进行有效性管理的设备。示例性的，如固定顺序分别为终端设备对应的预定义字段，第一网络设备对应的预定义字段，第二网络设备对应的预定义字段。预定义字段的取值为第一数值时，表示该预定义字段对应的设备为对候选小区的定时提前量TA进行有效性管理的设备。预定义字段的取值为第二数值时，表示该预定义字段对应的设备不为对候选小区的定时提前量TA进行有效性管理的设备。示例性的第一数值可以为1，第二数值可以为0。或者第一数值可以为0，第二数值可以为1等，本实施例中对第一数值和第二数值的具体取值不做限定。In yet another example, the first indication information may include three predefined fields in a fixed order, and a device that performs validity management of the timing advance TA of the candidate cell is determined based on the values of the predefined fields. For example, the fixed order is the predefined fields corresponding to the terminal device, the predefined fields corresponding to the first network device, and the predefined fields corresponding to the second network device. When the value of the predefined field is the first value, it indicates that the device corresponding to the predefined field is a device that performs validity management of the timing advance TA of the candidate cell. When the value of the predefined field is the second value, it indicates that the device corresponding to the predefined field is not a device that performs validity management of the timing advance TA of the candidate cell. An exemplary first value may be 1 and a second value may be 0. Or the first numerical value may be 0, the second numerical value may be 1, etc. In this embodiment, the specific values of the first numerical value and the second numerical value are not limited.
在再一种示例中，第一指示信息中可以包括固定一个预定义的字段，基于预定义的字段的取值确定对候选小区的定时提前量TA进行有效性管理的设备。示例性的，预定义字段的取值为第三数值时，表示对候选小区的定时提前量TA进行有效性管理的设备为终端设备，预定义字段的取值为第四数值时，表示对候选小区的定时提前量TA进行有效性管理的设备为第一网络设备，预定义字段的取值为第五数值时，表示对候选小区的定时提前量TA进行有效性管理的设备为第二网络设备。示例性的，第三数值可以为1，第四数值可以为2，第五数值为3。可以理解的是，第三数值，第四数值或第五数值还可以为其他具体取值，本实施例中对此不做限定。In another example, the first indication information may include fixing a predefined field, and determining a device for validity management of the timing advance TA of the candidate cell based on the value of the predefined field. For example, when the value of the predefined field is the third value, it indicates that the device that performs validity management of the timing advance TA of the candidate cell is a terminal device. When the value of the predefined field is the fourth value, it indicates that the device that performs validity management of the timing advance TA of the candidate cell is the terminal device. The device that performs validity management of the timing advance TA of the cell is the first network device. When the value of the predefined field is the fifth value, it indicates that the device that performs validity management of the timing advance TA of the candidate cell is the second network device. . For example, the third value may be 1, the fourth value may be 2, and the fifth value may be 3. It can be understood that the third numerical value, the fourth numerical value or the fifth numerical value can also be other specific values, which are not limited in this embodiment.
应理解，上文列举的第一指示信息中的具体指示方式仅为示例，不应对本申请构成任何限定。本申请对于第一网络设备如何指示对候选小区的定时提前量TA进行有效性管理的设备的具体方式不作限定。It should be understood that the specific indication methods in the first indication information listed above are only examples and should not constitute any limitation on this application. This application does not limit the specific manner of how the first network device instructs the device to perform validity management of the timing advance TA of the candidate cell.
在步骤202中，若对候选小区的TA进行有效性管理的设备为终端设备，则终端设备根据第一指示信息对候选小区的TA进行有效性管理。In step 202, if the device that performs validity management on the TA of the candidate cell is a terminal device, the terminal device performs validity management on the TA of the candidate cell according to the first instruction information.
换言之，终端设备根据第一指示信息中包括的内容即可确定出将要对候选小区的TA进行有效性管理的设备。若确定为终端设备，则终端设备就按照已经获取到的候选小区的TA对候选小区的TA进行有效性管理。其中，获取候选小区的TA的过程将在下一实施例中详细说明。In other words, the terminal device can determine the device that will perform validity management on the TA of the candidate cell based on the content included in the first indication information. If it is determined to be a terminal device, the terminal device performs validity management on the TA of the candidate cell according to the obtained TA of the candidate cell. The process of obtaining the TA of the candidate cell will be described in detail in the next embodiment.
在步骤203中，若对候选小区的TA进行有效性管理的设备为第一网络设备，则终端设备向第一网络设备发送第三指示信息，第一网络设备根据该第三指示信息对候选小区的TA进行有效性管理。该第三指示信息用于指示已获取对应候选小区的TA或TA值。In step 203, if the device that performs validity management on the TA of the candidate cell is the first network device, the terminal device sends third indication information to the first network device, and the first network device performs the validity management on the candidate cell based on the third indication information. TA conducts effectiveness management. The third indication information is used to indicate that the TA or TA value of the corresponding candidate cell has been obtained.
换言之，终端设备在确定对候选小区的TA进行有效性管理的设备为第一网络设备时，就根据已经获取到的候选小区的TA形成第三指示信息，并向第一网络设备发送该第三指示信息，由第一网络设备根据该第三指示信息对候选小区的TA进行有效性管理。In other words, when the terminal device determines that the device that performs validity management of the TA of the candidate cell is the first network device, it forms the third indication information based on the obtained TA of the candidate cell, and sends the third indication information to the first network device. Instruction information, the first network device performs validity management on the TA of the candidate cell according to the third instruction information.
那么在形成第三指示信息时，具体可以包括以下两种实现方式：Then when forming the third instruction information, the following two implementation methods may be included:
一种可能的实现方式是，按照已经获取到的候选小区的TA值形成第三指示信息，具体地，将候选小区的TA值与候选小区标识进行关联，例如，建立候选小区的TA值以及对应候选小区标识之间的映射关系，以按照关联结果形成第三指示信息。One possible implementation is to form the third indication information according to the obtained TA value of the candidate cell. Specifically, associate the TA value of the candidate cell with the candidate cell identifier, for example, establish the TA value of the candidate cell and the corresponding The mapping relationship between candidate cell identities is used to form third indication information according to the association result.
另一种可能的实现方式是，按照已经获取到候选小区的TA的结果形成第三指示信息。具体地，根据已经获取到候选小区的TA的结果形成一串特定字段，将候选小区对应的特定字段与候选小区标识进行关联，例如，建立候选小区对应的特定字段以及对应候选小区标识之间的映射关系，以按照关联结果形成第三指示信息。其中，特定字段表示已经获取到候选小区的TA。Another possible implementation is to form the third indication information according to the result that the TA of the candidate cell has been obtained. Specifically, a string of specific fields is formed based on the result of obtaining the TA of the candidate cell, and the specific fields corresponding to the candidate cell are associated with the candidate cell identifier. For example, a link between the specific field corresponding to the candidate cell and the corresponding candidate cell identifier is established. mapping relationship to form third indication information according to the association result. The specific field indicates that the TA of the candidate cell has been obtained.
可以理解的是，映射关系的表示方式可以为映射表格的形式或者其他形式，本实施例中对此不做限定。It can be understood that the mapping relationship can be expressed in the form of a mapping table or other forms, which is not limited in this embodiment.
其中，候选小区标识为指示候选小区身份的标识，例如，可以为候选小区的名称，或可以为表征候选小区身份的数字、字母或其他信息，本申请对此不作限定。The candidate cell identifier is an identifier indicating the identity of the candidate cell. For example, it may be the name of the candidate cell, or it may be numbers, letters or other information characterizing the identity of the candidate cell, which is not limited in this application.
应理解，当候选小区为多个，则在形成第三指示信息时可以按照已经获取到的全部候选小区的TA值形成第三指示信息。或者，可以按照已经获取到全部候选小区的TA的结果形成第三指示信息。或者，可以按照已经获取到的一部分候选小区的TA值以及已经获取到另一部分候选小区的TA的结果形成第三指示信息。第三指示信息的具体形式本申请不作限定。It should be understood that when there are multiple candidate cells, when forming the third indication information, the third indication information may be formed according to the TA values of all candidate cells that have been obtained. Alternatively, the third indication information may be formed according to the result that TAs of all candidate cells have been acquired. Alternatively, the third indication information may be formed based on the result that the TA values of a part of the candidate cells have been acquired and the TA values of another part of the candidate cells have been acquired. The specific form of the third instruction information is not limited in this application.
在步骤204中，若对候选小区的TA进行有效性管理的设备为第二网络设备，则终端设备向第二网络设备发送的第三指示信息，第二网络设备根据该第三指示信息对对应候选小区的TA进行有效性管理。In step 204, if the device that performs validity management of the TA of the candidate cell is a second network device, the terminal device sends the third instruction information to the second network device, and the second network device pairs the corresponding The TA of the candidate cell performs validity management.
如前，终端设备在确定对候选小区的TA进行有效性管理的设备为第二网络设备时，就根据已经获取到的候选小区的TA形成第三指示信息，并向第二网络设备发送该第三指示信息，由第二网络设备根据该第三指示信息对候选小区的TA进行有效性管理。As before, when the terminal device determines that the device that performs validity management of the TA of the candidate cell is the second network device, it forms the third indication information based on the obtained TA of the candidate cell, and sends the third indication information to the second network device. Third indication information, the second network device performs validity management on the TA of the candidate cell according to the third indication information.
应理解，此处形成第三指示信息的方式与步骤203中形成第三指示信息的方式类似，此处不再赘述。It should be understood that the method of forming the third instruction information here is similar to the method of forming the third instruction information in step 203, and will not be described again here.
因此，本申请实施例提供的定时提前量管理方法提供了三种对一个或多个候选小区的TA进行有效性管理的方式，即，基于终端设备或第一网络设备或第二网络设备对TA进行有效性管理。使得终端设备通过接收第一网络设备发送的第一指示信息，就可在确定第一指示信息指示终端设备时由终端设备对候选小区的TA进行有效性管理，在确定第一指示信息指示第一网络设备时由第一网络设备对候选小区的TA进行有效性管理，在确定第一指示信息指示第二网络设备时由第二网络设备对候选小区的TA进行有效性管理。从而使得不限于仅由网络设备进行管理，提高TA管理的灵活性。Therefore, the timing advance management method provided by the embodiment of the present application provides three ways to manage the validity of TAs of one or more candidate cells, that is, based on the terminal device or the first network device or the second network device, the TA Carry out effectiveness management. By receiving the first indication information sent by the first network device, the terminal device can perform validity management on the TA of the candidate cell when it is determined that the first indication information indicates the terminal device, and when it is determined that the first indication information indicates the first When the network device is configured, the first network device performs validity management on the TA of the candidate cell. When it is determined that the first indication information indicates the second network device, the second network device performs validity management on the TA of the candidate cell. As a result, it is not limited to management by network devices only and improves the flexibility of TA management.
在本申请的方法中，对候选小区的TA进行有效性管理的前提是终端设备已获取到至少一个候选小区的TA。所以对获取至少一个候选小区的TA的方式进行说明。In the method of this application, the prerequisite for validity management of the TA of the candidate cell is that the terminal device has obtained the TA of at least one candidate cell. Therefore, the method of obtaining the TA of at least one candidate cell is explained.
一种可能的实现方式是，如图3所示，当第一网络设备向终端设备发送第一指示信息时，在步骤301中，第一网络设备还可向终端设备发送第二指示信息，该第二指示信息用于指示无竞争随机接入CFRA过程是否包括随机接入响应RAR。在步骤302中，终端设备根据第二指示信息向第二网络设备发送CFRA请求，该CFRA请求用于指示第二网络设备获取对应候选小区的TA。在步骤303中，第二网络设备基于CFRA请求判断该CFRA过程是否包括RAR，若是，则在步骤304中，第二网络设备向终端设备发送RAR，该RAR包括对应候选小区的TA。One possible implementation is, as shown in Figure 3, when the first network device sends the first indication information to the terminal device, in step 301, the first network device may also send the second indication information to the terminal device. The second indication information is used to indicate whether the contention-free random access CFRA process includes a random access response RAR. In step 302, the terminal device sends a CFRA request to the second network device according to the second indication information. The CFRA request is used to instruct the second network device to obtain the TA of the corresponding candidate cell. In step 303, the second network device determines whether the CFRA process includes a RAR based on the CFRA request. If so, in step 304, the second network device sends a RAR to the terminal device, where the RAR includes the TA corresponding to the candidate cell.
应理解，终端设备可以根据第二指示信息中包括的内容向第二网络设备发送CFRA请求，其中，第二指示信息包括：是否在CFRA过程中包括RAR。It should be understood that the terminal device may send a CFRA request to the second network device according to the content included in the second indication information, where the second indication information includes: whether to include RAR in the CFRA process.
那么第二指示信息在指示CFRA过程是否包括RAR时，可以在其包含的某一预定义字段中承载是否在CFRA过程中包括RAR的指示信息。例如，该预定义字段为第六数值或第七数值。第六数值或第七数值可以为预定义的数字、字母或符号等其他信息，本申请对此不作限定。Then, when the second indication information indicates whether the CFRA process includes the RAR, a certain predefined field contained in the second indication information may carry the indication information of whether the CFRA process includes the RAR. For example, the predefined field is the sixth value or the seventh value. The sixth numerical value or the seventh numerical value may be predefined numbers, letters, symbols or other information, which is not limited in this application.
其中，第六数值可以为在CFRA过程中包括RAR的指示信息，第七数值为不在CFRA过程中包括RAR的指示信息。或者，第七数值可以为在CFRA过程中包括RAR的指示信息，第六数值为不在CFRA过程中包括RAR的指示信息。本申请对此不作限定。The sixth value may be indication information for including RAR in the CFRA process, and the seventh value may be indication information for not including RAR in the CFRA process. Alternatively, the seventh value may be indication information for including RAR in the CFRA process, and the sixth value may be indication information for not including RAR in the CFRA process. This application does not limit this.
示例性地，第二指示信息中的预定义字段的取值为1，则代表在CFRA过程中包括RAR的指示信息，该预定义字段的取值为0，则代表不在CFRA过程中包括RAR的指示信息。For example, if the value of the predefined field in the second indication information is 1, it means that the indication information of RAR is included in the CFRA process; if the value of the predefined field is 0, it means that the indication information of RAR is not included in the CFRA process. Instructions.
此外，第二指示信息还可以隐式地表达是否在CFRA过程中包括RAR的指示信息。例如，第二指示信息可以为“包括RAR”的字段、“包括RAR”的标识、“包括RAR”的索引等信息，可以通过上述指示信息表达在CFRA过程中包括RAR。而若第二指示信息不为“包括RAR”的字段、“包括RAR”的标识、“包括RAR”的索引等信息，而是为与“包括RAR”无关的信息，例如NULL或者“不包括RAR”的字段、“不包括RAR”的标识、“不包括RAR”的索引等信息，则可以代表不在CFRA过程中包括RAR的指示信息。In addition, the second indication information may also implicitly express indication information of whether to include RAR in the CFRA process. For example, the second indication information may be a field of "Include RAR", an identifier of "Include RAR", an index of "Include RAR", and other information, and the inclusion of RAR in the CFRA process can be expressed through the above indication information. And if the second indication information is not the field of "Include RAR", the identifier of "Include RAR", the index of "Include RAR", etc., but is information irrelevant to "Include RAR", such as NULL or "Do not include RAR" " field, "RAR not included" identifier, "RAR not included" index and other information can represent instruction information not to include RAR in the CFRA process.
基于此，终端设备有两种可选择的方式向第二网络设备发起CFRA请求。其一为向第二网络设备发起不包括RAR的CFRA过程，其二为向第二网络设备发起包括RAR的CFRA过程。因此，当第二网络设备接收到终端设备发送的CFRA请求之后，需要判断该CFRA过程是否包括RAR，并在确定包括时将对应候选小区的TA存储在RAR中，并将该RAR发送至终端设备。Based on this, the terminal device has two optional ways to initiate a CFRA request to the second network device. The first is to initiate a CFRA process that does not include RAR to the second network device, and the second is to initiate a CFRA process that includes RAR to the second network device. Therefore, when the second network device receives the CFRA request sent by the terminal device, it needs to determine whether the CFRA process includes RAR, and when it is determined that it does, store the TA of the corresponding candidate cell in the RAR, and send the RAR to the terminal device. .
在第二网络设备判断该CFRA过程是否包括RAR时，可通过以下方式进行：When the second network device determines whether the CFRA process includes RAR, it may be performed in the following manner:
在一种示例中，当终端设备发起不包括RAR的CFRA过程，终端设备不会在CFRA请求中包含与“包括RAR”相关的指示信息，例如，包含与“不包括RAR”相关的指示信息或者设置空白值。当终端设备发起包括RAR的CFRA过程，终端设备会在CFRA请求中包含与“包括RAR”相关的指示信息。相应地，第二网络设备在判断该CFRA过程是否包括RAR时，根据所接收到的CFRA请求中包含的内容，即可确定该CFRA过程是否包括RAR。In one example, when the terminal device initiates a CFRA process that does not include RAR, the terminal device does not include indication information related to "including RAR" in the CFRA request, for example, includes indication information related to "excluding RAR" or Set blank value. When the terminal device initiates a CFRA process that includes RAR, the terminal device will include indication information related to "including RAR" in the CFRA request. Correspondingly, when the second network device determines whether the CFRA process includes RAR, it can determine whether the CFRA process includes RAR based on the content contained in the received CFRA request.
在另一种示例中，当终端设备发起包括RAR的CFRA过程，终端设备会形成一个与“包括RAR”相关的独立信令，并将该信令与CFRA请求同时发送至第二网络设备。当终端设备发起不包括RAR的CFRA过程，终端设备会形成一个与“不包括RAR”相关的独立信令，并将该信令与CFRA请求同时发送至第二网络设备，或者，终端设备不会形成任何信令，仅将CFRA请求发送至第二网络设备。相应地，第二网络设备在判断该CFRA过程是否包括RAR时，根据CFRA请求确定该CFRA过程是否包括RAR或者根据CFRA请求及与CFRA请求一同发送过来的信令确定该CFRA过程是否包括RAR。In another example, when the terminal device initiates a CFRA process including RAR, the terminal device will form an independent signaling related to "including RAR" and send the signaling to the second network device simultaneously with the CFRA request. When the terminal device initiates a CFRA process that does not include RAR, the terminal device will form an independent signaling related to "not including RAR" and send the signaling and the CFRA request to the second network device at the same time, or the terminal device will not Form any signaling, only the CFRA request is sent to the second network device. Correspondingly, when determining whether the CFRA process includes RAR, the second network device determines whether the CFRA process includes RAR according to the CFRA request or determines whether the CFRA process includes RAR according to the CFRA request and the signaling sent together with the CFRA request.
还应理解，本申请对与“包括RAR”相关的指示信息、与“不包括RAR”相关的指示信息、与“包括RAR”相关的独立信令、与“不包括RAR”相关的独立信令的具体表现形式不作限定。且上述示例仅为举例，不应对本申请构成任何限定。It should also be understood that this application refers to the indication information related to "including RAR", the indication information related to "not including RAR", the independent signaling related to "including RAR", and the independent signaling related to "not including RAR". The specific form of expression is not limited. And the above examples are only examples and should not constitute any limitation on this application.
还应理解，上述第二指示信息中包括的内容仅为举例，不应对本申请构成任何限定。因此，上述获取至少一个候选小区的TA的方法中，通过采用第二指示信息触发终端设备对CFRA过程是否包括RAR的决策，使得终端设备在发起包括RAR的CFRA过程之后，能够利用RAR顺利获得第二网络设备返回的TA，相较于发送新的指令获取TA，节省了传输资源。It should also be understood that the content included in the above-mentioned second instruction information is only an example and should not constitute any limitation on this application. Therefore, in the above method of obtaining the TA of at least one candidate cell, the second indication information is used to trigger the terminal equipment's decision on whether the CFRA process includes RAR, so that the terminal equipment can use RAR to successfully obtain the third TA after initiating the CFRA process including RAR. The TA returned by the second network device saves transmission resources compared to sending new instructions to obtain the TA.
另一种可能的实现方式是，终端设备向第二网络设备发送包括RAR的CFRA请求，该包括RAR的CFRA请求用于指示CFRA过程包括RAR。第二网络设备向终端设备发送RAR，RAR包括对应候选小区的TA。Another possible implementation is that the terminal device sends a CFRA request including RAR to the second network device, where the CFRA request including RAR is used to indicate that the CFRA process includes RAR. The second network device sends a RAR to the terminal device, where the RAR includes the TA corresponding to the candidate cell.
需要说明的是，在这种可能的实现方式中，终端设备是基于第一指示信息自行触发包括RAR的CFRA过程，以获得第二网络设备发送的包括对应候选小区的TA的RAR。It should be noted that in this possible implementation, the terminal device triggers the CFRA process including the RAR on its own based on the first indication information, so as to obtain the RAR sent by the second network device including the TA of the corresponding candidate cell.
换言之，该实现方式与上一实现方式的不同在于，本实现方式中，终端设备无需接收第一网络设备发送的第二指示信息，可以在接收第一网络设备发送的第一指示信息之后，自发地触发包括RAR的CFRA过程。其中，该自发地触发包括RAR的CFRA过程与上一实现方式中当终端设备发起包括RAR的CFRA过程所采用的方式类似，此处不再赘述。因此，上述获取至少一个候选小区的TA的方法中，通过触发终端设备自行发送包括RAR的CFRA请求的执行动作，提高获取候选小区TA的效率。In other words, the difference between this implementation mode and the previous implementation mode is that in this implementation mode, the terminal device does not need to receive the second instruction information sent by the first network device, and can spontaneously receive the first instruction information sent by the first network device. Trigger the CFRA process including RAR. The spontaneous triggering of the CFRA process including RAR is similar to the method used when the terminal device initiates the CFRA process including RAR in the previous implementation, and will not be described again here. Therefore, in the above method of obtaining the TA of at least one candidate cell, the efficiency of obtaining the TA of the candidate cell is improved by triggering the terminal device to send an execution action of a CFRA request including a RAR on its own.
应理解，本申请可采用两种方式中的一种来获取候选小区的TA，所以有效提高了获取候选小区的TA的灵活性。It should be understood that this application can adopt one of two methods to obtain the TA of the candidate cell, so the flexibility of obtaining the TA of the candidate cell is effectively improved.
基于上述两种可能的实现方式还需要进一步说明，即终端设备向第二网络设备发送CFRA相关请求的前提是终端设备当前已经获取到CFRA资源。这就涉及到，由终端设备向第一网络设备发送CFRA资源获取请求，由第一网络设备将CFRA资源存储至PDCCH指令中，并将PDCCH指令返回至终端设备，使之获得CFRA资源。该CFRA资源获取请求为请求获取CFRA资源的请求。该CFRA资源包括随机接入的时机RACH occasion以及随机接入的前导码索引Preamble index，该RACH occasion用于指示终端设备在哪个时间点发起CFRA，该Preambleindex用于指示终端设备在那个前导码上进行CFRA。Based on the above two possible implementation methods, further explanation is needed, that is, the premise for the terminal device to send the CFRA-related request to the second network device is that the terminal device has currently obtained the CFRA resource. This involves the terminal device sending a CFRA resource acquisition request to the first network device, the first network device storing the CFRA resource in the PDCCH command, and returning the PDCCH command to the terminal device so that it can obtain the CFRA resource. The CFRA resource acquisition request is a request to acquire CFRA resources. The CFRA resource includes the random access opportunity RACH occasion and the preamble index Preamble index of the random access. The RACH occasion is used to indicate at which time point the terminal device initiates CFRA. The Preamble index is used to indicate the terminal device to initiate CFRA on which preamble. CFRA.
应理解，CFRA相关请求是对CFRA请求以及包括RAR的CFRA请求的一种概括表述，在提到CFRA相关请求时，可理解为CFRA请求或包括RAR的CFRA请求。不应与CFRA请求或包括RAR的CFRA请求分开理解。It should be understood that CFRA-related request is a general expression of CFRA request and CFRA request including RAR. When referring to CFRA-related request, it can be understood as CFRA request or CFRA request including RAR. should not be understood separately from CFRA requests or CFRA requests including RARs.
还应理解，第一网络设备在向终端设备发送第一指示信息和第二指示信息时，可以一同发送也可以分开发送，具体的发送方式本申请不作限定。下面对第一指示信息和第二指示信息的传输方式进行详细说明。It should also be understood that when the first network device sends the first indication information and the second indication information to the terminal device, it may send them together or separately, and the specific sending method is not limited in this application. The transmission method of the first indication information and the second indication information will be described in detail below.
在一种示例中，第一指示信息和第二指示信息可以承载在物理下行控制信道调度PDCCH指令中。具体地，当终端设备向第一网络设备发送CFRA资源获取请求，第一网络设备将第一指示信息和第二指示信息连同PDCCH指令发送至终端设备。在此情况下，第一指示信息和第二指示信息可以分别是PDCCH指令中某一预定义的字段。这种在PDCCH指令中同时承载第一指示信息和第二指示信息的方式可以避免额外传输带来的资源浪费。In an example, the first indication information and the second indication information may be carried in a physical downlink control channel scheduling PDCCH instruction. Specifically, when the terminal device sends a CFRA resource acquisition request to the first network device, the first network device sends the first indication information and the second indication information together with the PDCCH instruction to the terminal device. In this case, the first indication information and the second indication information may respectively be a certain predefined field in the PDCCH instruction. This method of simultaneously carrying the first indication information and the second indication information in the PDCCH instruction can avoid resource waste caused by additional transmission.
在另一种示例中，第一指示信息和第二指示信息承载在无限资源控制RRC重配置信令消息中。具体地，当第一网络设备在某个小区切换机制下得到候选小区配置信息并基于该候选小区配置信息形成RRC重配置信令消息，第一网络设备将第一指示信息和第二指示信息连同RRC重配置信令消息发送至终端设备。在此情况下，第一指示信息和第二指示信息可以分别是RRC重配置信令消息中某一预定义的字段。这种在RRC重配置信令消息中同时承载第一指示信息和第二指示信息的方式亦可以避免额外传输带来的资源浪费。In another example, the first indication information and the second indication information are carried in a wireless resource control RRC reconfiguration signaling message. Specifically, when the first network device obtains the candidate cell configuration information under a certain cell switching mechanism and forms an RRC reconfiguration signaling message based on the candidate cell configuration information, the first network device combines the first indication information and the second indication information. The RRC reconfiguration signaling message is sent to the terminal device. In this case, the first indication information and the second indication information may respectively be a certain predefined field in the RRC reconfiguration signaling message. This method of simultaneously carrying the first indication information and the second indication information in the RRC reconfiguration signaling message can also avoid resource waste caused by additional transmission.
在又一种示例中，第一指示信息承载在PDCCH指令中且第二指示信息承载在RRC重配置信令消息中。具体地，当终端设备向第一网络设备发送CFRA资源获取请求，第一网络设备将第一指示信息连同PDCCH指令发送至终端设备。当第一网络设备在某个小区切换机制下得到候选小区配置信息并基于该候选小区配置信息形成RRC重配置信令消息，第一网络设备将第二指示信息连同RRC重配置信令消息发送至终端设备。由于PDCCH指令和RRC重配置信令消息均为执行对候选小区的TA进行有效性管理所需的内容，所以这种在PDCCH指令中承载第一指示信息，在RRC重配置信令消息中承载第二指示信息的方式同样可以避免额外传输带来的资源浪费。In yet another example, the first indication information is carried in the PDCCH instruction and the second indication information is carried in the RRC reconfiguration signaling message. Specifically, when the terminal device sends a CFRA resource acquisition request to the first network device, the first network device sends the first indication information together with the PDCCH instruction to the terminal device. When the first network device obtains the candidate cell configuration information under a certain cell handover mechanism and forms an RRC reconfiguration signaling message based on the candidate cell configuration information, the first network device sends the second indication information together with the RRC reconfiguration signaling message to Terminal Equipment. Since both the PDCCH instruction and the RRC reconfiguration signaling message are required to perform validity management of the TA of the candidate cell, the first instruction information is carried in the PDCCH instruction, and the second instruction information is carried in the RRC reconfiguration signaling message. The second indication information method can also avoid the waste of resources caused by additional transmission.
在还一种示例中，第一指示信息承载在RRC重配置信令消息中且第二指示信息承载在PDCCH指令中。具体地，当第一网络设备在某个小区切换切换机制下得到候选小区配置信息并基于该候选小区配置信息形成RRC重配置信令消息，第一网络设备将第一指示信息连同RRC重配置信令消息发送至终端设备。当终端设备向第一网络设备发送CFRA资源获取请求，第一网络设备将第二指示信息连同PDCCH指令发送至终端设备。同理，由于PDCCH指令和RRC重配置信令消息均为执行对候选小区的TA进行有效性管理所需的内容，所以这种在RRC重配置信令消息中承载第一指示信息，在PDCCH指令中承载第二指示信息的方式同样可以避免额外传输带来的资源浪费。In yet another example, the first indication information is carried in the RRC reconfiguration signaling message and the second indication information is carried in the PDCCH instruction. Specifically, when the first network device obtains the candidate cell configuration information under a certain cell handover mechanism and forms an RRC reconfiguration signaling message based on the candidate cell configuration information, the first network device sends the first indication information together with the RRC reconfiguration signaling message. Send the message to the terminal device. When the terminal device sends a CFRA resource acquisition request to the first network device, the first network device sends the second indication information together with the PDCCH instruction to the terminal device. Similarly, since both the PDCCH instruction and the RRC reconfiguration signaling message are required to perform validity management of the TA of the candidate cell, the first indication information is carried in the RRC reconfiguration signaling message, and the first indication information is carried in the PDCCH instruction. The method of carrying the second indication information in can also avoid the waste of resources caused by additional transmission.
应理解，上述的多种发送第一指示信息及第二指示信息的方式，使得第一网络设备可以根据不同的发送方式发送第一指示信息及第二指示信息，提高发送第一指示信息及第二指示信息的灵活性。It should be understood that the above-mentioned multiple ways of sending the first indication information and the second indication information enable the first network device to send the first indication information and the second indication information according to different sending ways, thereby improving the efficiency of sending the first indication information and the second indication information. 2. Indicate the flexibility of information.
应理解，第一指示信息和第二指示信息还可以作为同一条独立信令通过第一网络设备发送至终端设备。也可以分别作为一条独立信令通过第一网络设备发送至终端设备，具体发送方式本申请不作限定。It should be understood that the first indication information and the second indication information can also be sent to the terminal device through the first network device as the same independent signaling. It can also be sent to the terminal device through the first network device as an independent signaling, and the specific sending method is not limited in this application.
还应理解，当第一指示信息和第二指示信息同时承载在PDCCH指令中或RRC重配置信令消息中时，第一指示信息和第二指示信息还可以作为同一个指示信息承载在PDCCH指令中或RRC重配置信令消息中，该同一个指示信息的具体表现形式本申请不作限定。It should also be understood that when the first indication information and the second indication information are carried in the PDCCH instruction or the RRC reconfiguration signaling message at the same time, the first indication information and the second indication information can also be carried in the PDCCH instruction as the same indication information. In the RRC reconfiguration signaling message or in the RRC reconfiguration signaling message, the specific expression form of the same indication information is not limited in this application.
需要说明的是，终端设备在得到至少一个候选小区的TA之后，若根据第一指示信息确定由终端设备对候选小区的TA进行有效性管理，则根据所获取到的至少一个候选小区的TA对对应候选小区的TA进行有效性管理。若根据第一指示信息确定由第一网络设备对候选小区的TA进行有效性管理，则基于至少一个候选小区的TA形成第三指示信息，并将其发送至第一网络设备。若根据第一指示信息确定由第二网络设备对候选小区的TA进行有效性管理，则同样地基于至少一个候选小区的TA形成第三指示信息，并将其发送至第二网络设备。使得第一网络设备和第二网络设备均可根据第三指示信息对候选小区的TA进行有效性管理。It should be noted that, after the terminal device obtains the TA of at least one candidate cell, if it is determined according to the first indication information that the terminal device performs validity management on the TA of the candidate cell, it will Validity management is performed on the TA corresponding to the candidate cell. If it is determined according to the first indication information that the first network device performs validity management on the TA of the candidate cell, third indication information is formed based on the TA of at least one candidate cell and is sent to the first network device. If it is determined according to the first indication information that the second network device performs validity management on the TA of the candidate cell, similarly form third indication information based on the TA of at least one candidate cell and send it to the second network device. This allows both the first network device and the second network device to perform validity management on the TA of the candidate cell according to the third indication information.
还需要说明的是，基于第一指示信息不同的承载方式，当终端设备自行触发包括RAR的CFRA过程时，若第一指示信息承载在PDCCH指令或RRC重配置信令消息中，则终端设备可以基于PDCCH指令自行触发包括RAR的CFRA过程，也可以基于RRC重配置信令消息自行触发包括RAR的CFRA过程。若第一指示信息为一条独立信令，则终端设备可以基于该独立信令自行触发包括RAR的CFRA过程，亦可以基于PDCCH指令自行触发包括RAR的CFRA过程，也可以基于RRC重配置信令消息自行触发包括RAR的CFRA过程。本申请对此不做限定。It should also be noted that based on the different carrying modes of the first indication information, when the terminal equipment triggers the CFRA process including RAR on its own, if the first indication information is carried in the PDCCH instruction or the RRC reconfiguration signaling message, the terminal equipment can The CFRA process including RAR can be triggered on its own based on the PDCCH instruction, or the CFRA process including RAR can be triggered on its own based on the RRC reconfiguration signaling message. If the first indication information is an independent signaling, the terminal device can trigger the CFRA process including RAR on its own based on the independent signaling, can also trigger the CFRA process including RAR on its own based on the PDCCH instruction, or can also trigger the CFRA process including RAR based on the RRC reconfiguration signaling message. Self-trigger CFRA process including RAR. This application does not limit this.
下面分别以对候选小区的定时提前量TA进行有效性管理的设备为终端设备、第一网络设备或第二网络设备时，对候选小区的TA进行有效性管理的方案进行详细介绍。The following is a detailed introduction to the solution for managing the validity of the TA of the candidate cell when the device that performs validity management of the timing advance TA of the candidate cell is a terminal device, a first network device, or a second network device.
一、对候选小区的定时提前量TA进行有效性管理的设备为终端设备。1. The device that manages the validity of the timing advance TA of the candidate cell is the terminal device.
在上述实施例提供的定时提前量管理方法中，在终端设备接收第一网络设备发送的第一指示信息，以及获取到候选小区的TA之外，为了能够实现终端设备对候选小区的TA的有效性管理，还要获取进行有效性管理的相关信息。In the timing advance management method provided in the above embodiment, in addition to the terminal device receiving the first indication information sent by the first network device and obtaining the TA of the candidate cell, in order to enable the terminal device to effectively validate the TA of the candidate cell sexual management, but also to obtain relevant information for effectiveness management.
那么进行有效性管理的相关信息可以包括第一配置信息和第二配置信息。Then the relevant information for validity management may include first configuration information and second configuration information.
所以可选地，获取第一配置信息和第二配置信息，具体可以包括：Therefore, optionally, obtaining the first configuration information and the second configuration information may include:
第一网络设备向终端设备发送第一配置信息和第二配置信息。The first network device sends first configuration information and second configuration information to the terminal device.
其中，该第一配置信息为表征候选小区TA有效的配置信息，该第一配置信息包括：候选小区的TA公共有效时长及超过公共有效时长TA失效的信息，或者，对应候选小区的TA私有有效时长及超过私有有效时长对应TA失效的信息。该第二配置信息为表征候选小区TA在有效期内进行更新的配置信息，该第二配置信息为候选小区的TA公共更新时长阈值或对应候选小区的TA私有更新时长阈值。Wherein, the first configuration information is configuration information indicating that the TA of the candidate cell is valid. The first configuration information includes: the public validity period of the TA of the candidate cell and the information of TA failure exceeding the public validity period, or the TA private validity corresponding to the candidate cell. Duration and information exceeding the private validity period correspond to TA failure. The second configuration information is configuration information indicating that the candidate cell TA is updated within the validity period. The second configuration information is the TA public update duration threshold of the candidate cell or the TA private update duration threshold of the corresponding candidate cell.
下面对第一配置信息和第二配置信息中包括的信息进行详细介绍。The information included in the first configuration information and the second configuration information is introduced in detail below.
该公共有效时长是为全部候选小区的TA所设置的一个共有时长，在此时长内全部候选小区的TA均具有有效性。这种设置方式可以减少第一配置信息所占用的字段，节省传输资源。The common valid period is a common period set for the TAs of all candidate cells. Within this period, the TAs of all candidate cells are valid. This setting method can reduce the fields occupied by the first configuration information and save transmission resources.
该私有有效时长是为对应候选小区的TA所设置的对应时长，在该私有有效时长内对应候选小区的TA具有有效性。这种设置方式可以使各候选小区TA的对应时长更加适配各候选小区，提高设置的准确性。The private valid period is a corresponding period set for the TA corresponding to the candidate cell. Within the private valid period, the TA corresponding to the candidate cell is valid. This setting method can make the corresponding duration of each candidate cell TA more suitable for each candidate cell and improve the accuracy of the setting.
该公共更新时长阈值是在全部候选小区的TA设置了公共有效时长的基础上为全部候选小区的TA所设置的一个共有更新时长阈值。该私有更新时长阈值是在各个候选小区的TA设置了对应私有有效时长的基础上为各个候选小区的TA所设置的对应更新时长阈值。The common update duration threshold is a common update duration threshold set for the TAs of all candidate cells on the basis that the TAs of all candidate cells have set a common effective duration. The private update duration threshold is a corresponding update duration threshold set for the TA of each candidate cell on the basis that the TA of each candidate cell has set a corresponding private effective duration.
进一步地，该候选小区的TA公共更新时长阈值为小于公共有效时长的数值或剩余公共有效时长的数值，该剩余公共有效时长为启动TA计时器时公共有效时长与计时时间的差值。该对应候选小区的TA私有更新时长阈值为小于私有有效时长的数值或小于剩余私有有效时长的数值，该剩余私有有效时长为启动TA计时器时私有有效时长与计时时间的差值。Further, the TA public update duration threshold of the candidate cell is a value less than the public valid duration or a value of the remaining public valid duration, and the remaining public valid duration is the difference between the public valid duration and the timing time when the TA timer is started. The TA private update duration threshold of the corresponding candidate cell is a value smaller than the private valid duration or a value smaller than the remaining private valid duration. The remaining private valid duration is the difference between the private valid duration and the timing time when the TA timer is started.
为了更为清楚地说明候选小区的TA公共更新时长阈值或候选小区的TA私有更新时长阈值的设置规则，下面示例性地列举一个场景进行详细说明。In order to more clearly explain the setting rules for the TA public update duration threshold of the candidate cell or the TA private update duration threshold of the candidate cell, a scenario is exemplified below for detailed description.
在一种场景中，需要在候选小区的TA失效前10毫秒触发候选小区的TA更新。那么当设置候选小区的TA公共有效时长为50毫秒时，存在两种方法设置公共更新时长阈值。In one scenario, the TA update of the candidate cell needs to be triggered 10 milliseconds before the TA of the candidate cell expires. Then, when setting the TA public effective duration of the candidate cell to 50 milliseconds, there are two methods to set the common update duration threshold.
其一，设置候选小区的TA公共更新时长阈值为小于公共有效时长的数值。即设置候选小区的TA公共更新时长阈值为40毫秒，那么当计时时间达到40毫秒时即触发候选小区的TA更新。First, set the TA public update duration threshold of the candidate cell to a value smaller than the public effective duration. That is, the TA public update duration threshold of the candidate cell is set to 40 milliseconds, and then when the timing time reaches 40 milliseconds, the TA update of the candidate cell is triggered.
其二，设置候选小区的TA公共更新时长阈值为剩余公共有效时长的数值。Second, set the TA public update duration threshold of the candidate cell to the value of the remaining public valid duration.
应理解，在本场景中，剩余公共有效时长即为候选小区的TA公共有效时长50毫秒与已经过去的计时时间40毫秒的差值，即10毫秒。因此，设置候选小区的TA公共更新时长阈值为10毫秒，那么当计时时间达到40毫秒时即触发候选小区的TA更新。It should be understood that in this scenario, the remaining public valid duration is the difference between the candidate cell's TA public valid duration of 50 milliseconds and the elapsed timing time of 40 milliseconds, that is, 10 milliseconds. Therefore, if the TA public update duration threshold of the candidate cell is set to 10 milliseconds, then when the timing reaches 40 milliseconds, the TA update of the candidate cell is triggered.
应理解，第一配置信息和第二配置信息是同时存在的，终端设备可以根据第一配置信息和第二配置信息对候选小区TA进行有效性管理，那么针对不同的第一配置信息和不同的第二配置信息，所得到的第一配置信息和第二配置信息的搭配可以为以下两种搭配中的任意一种：It should be understood that the first configuration information and the second configuration information exist at the same time, and the terminal device can perform validity management on the candidate cell TA according to the first configuration information and the second configuration information. Then, for different first configuration information and different For the second configuration information, the obtained combination of the first configuration information and the second configuration information can be any one of the following two combinations:
（1）第一配置信息中包括候选小区的TA公共有效时长及超过公共有效时长TA失效的信息，第二配置信息中包括候选小区的TA公共更新时长阈值。(1) The first configuration information includes the TA public validity period of the candidate cell and information on TA failure exceeding the public validity period, and the second configuration information includes the TA public update duration threshold of the candidate cell.
（2）第一配置信息中包括对应候选小区的TA私有有效时长及超过私有有效时长对应TA失效的信息，第二配置信息中包括对应候选小区的TA私有更新时长阈值。(2) The first configuration information includes the TA private validity period corresponding to the candidate cell and the information that the TA expires when the private validity period exceeds. The second configuration information includes the TA private update duration threshold corresponding to the candidate cell.
那么针对不同的搭配，具体含义如下：So for different combinations, the specific meanings are as follows:
若第一配置信息中包括候选小区的TA公共有效时长及超过公共有效时长TA失效的信息，第二配置信息中包括候选小区的TA公共更新时长阈值，则说明各个候选小区的TA具有相同的有效时长以及相同的更新时长阈值。If the first configuration information includes the public validity period of the TA of the candidate cell and the information of TA failure exceeding the public validity period, and the second configuration information includes the public update duration threshold of the TA of the candidate cell, it means that the TA of each candidate cell has the same validity. duration and the same update duration threshold.
同理，若第一配置信息中包括对应候选小区的TA私有有效时长及超过私有有效时长对应TA失效的信息，第二配置信息中包括对应候选小区的TA私有更新时长阈值，则说明各个候选小区的TA可以具有互不相同的有效时长并且在此基础上可以具有互不相同的更新时长阈值。因此，本实施例提供了第一配置信息和第二配置信息，并在此基础上提出了多种第一配置信息和第二配置信息的搭配，使得终端设备可以基于多种第一配置信息和第二配置信息的搭配对候选小区的TA进行有效性管理，提高终端设备管理的灵活性。Similarly, if the first configuration information includes the TA private validity period corresponding to the candidate cell and the information that the TA expires if the private validity period exceeds the private validity period, and the second configuration information includes the TA private update duration threshold corresponding to the candidate cell, then it means that each candidate cell The TAs may have different valid durations and based on this, may have different update duration thresholds. Therefore, this embodiment provides the first configuration information and the second configuration information, and on this basis proposes a variety of combinations of the first configuration information and the second configuration information, so that the terminal device can be based on a variety of first configuration information and the second configuration information. The matching of the second configuration information performs validity management on the TA of the candidate cell, thereby improving the flexibility of terminal equipment management.
还应理解，第一网络设备在向终端设备发送第一配置信息和第二配置信息时，可以一同发送也可以分开发送，具体的发送方式本申请不作限定。下面对第一配置信息和第二配置信息的传输方式进行详细说明。It should also be understood that when the first network device sends the first configuration information and the second configuration information to the terminal device, it can send them together or separately, and the specific sending method is not limited in this application. The transmission method of the first configuration information and the second configuration information will be described in detail below.
在一种示例中，第一配置信息和第二配置信息可以承载在物理下行控制信道调度PDCCH指令中。具体地，当终端设备向第一网络设备发送CFRA资源获取请求，第一网络设备将第一配置信息和第二配置信息连同PDCCH指令发送至终端设备。在此情况下，第一配置信息和第二配置信息可以分别是PDCCH指令中某一预定义的字段。这种在PDCCH指令中同时承载第一配置信息和第二配置信息的方式可以避免额外传输带来的资源浪费。In an example, the first configuration information and the second configuration information may be carried in a physical downlink control channel scheduling PDCCH instruction. Specifically, when the terminal device sends a CFRA resource acquisition request to the first network device, the first network device sends the first configuration information and the second configuration information together with the PDCCH instruction to the terminal device. In this case, the first configuration information and the second configuration information may respectively be certain predefined fields in the PDCCH instruction. This method of simultaneously carrying the first configuration information and the second configuration information in the PDCCH instruction can avoid resource waste caused by additional transmission.
在另一种示例中，第一配置信息和第二配置信息承载在无限资源控制RRC重配置信令消息中。具体地，当第一网络设备在某个小区切换机制下得到候选小区配置信息并基于该候选小区配置信息形成RRC重配置信令消息，第一网络设备将第一配置信息和第二配置信息连同RRC重配置信令消息发送至终端设备。在此情况下，第一配置信息和第二配置信息可以分别是RRC重配置信令消息中某一预定义的字段。这种在RRC重配置信令消息中同时承载第一配置信息和第二配置信息的方式亦可以避免额外传输带来的资源浪费。In another example, the first configuration information and the second configuration information are carried in a wireless resource control RRC reconfiguration signaling message. Specifically, when the first network device obtains the candidate cell configuration information under a certain cell switching mechanism and forms an RRC reconfiguration signaling message based on the candidate cell configuration information, the first network device combines the first configuration information and the second configuration information. The RRC reconfiguration signaling message is sent to the terminal device. In this case, the first configuration information and the second configuration information may respectively be a certain predefined field in the RRC reconfiguration signaling message. This method of simultaneously carrying the first configuration information and the second configuration information in the RRC reconfiguration signaling message can also avoid resource waste caused by additional transmission.
在又一种示例中，第一配置信息承载在PDCCH指令中且第二配置信息承载在RRC重配置信令消息中。具体地，当终端设备向第一网络设备发送CFRA资源获取请求，第一网络设备将第一配置信息连同PDCCH指令发送至终端设备。当第一网络设备在某个小区切换机制下得到候选小区配置信息并基于该候选小区配置信息形成RRC重配置信令消息，第一网络设备将第二配置信息连同RRC重配置信令消息发送至终端设备。由于PDCCH指令和RRC重配置信令消息均为执行小区切换时需要交互的，而对候选小区的TA进行有效性管理也是在小区切换时的内容，所以这种在PDCCH指令中承载第一配置信息，在RRC重配置信令消息中承载第二配置信息的方式同样可以避免额外传输带来的资源浪费。In yet another example, the first configuration information is carried in the PDCCH instruction and the second configuration information is carried in the RRC reconfiguration signaling message. Specifically, when the terminal device sends a CFRA resource acquisition request to the first network device, the first network device sends the first configuration information together with the PDCCH instruction to the terminal device. When the first network device obtains the candidate cell configuration information under a certain cell handover mechanism and forms an RRC reconfiguration signaling message based on the candidate cell configuration information, the first network device sends the second configuration information together with the RRC reconfiguration signaling message to Terminal Equipment. Since both the PDCCH instruction and the RRC reconfiguration signaling message need to be interacted when performing cell handover, and the validity management of the TA of the candidate cell is also part of the cell handover, the first configuration information is carried in the PDCCH instruction. , the method of carrying the second configuration information in the RRC reconfiguration signaling message can also avoid resource waste caused by additional transmission.
在还一种示例中，第一配置信息承载在RRC重配置信令消息中且第二配置信息承载在PDCCH指令中。具体地，当第一网络设备在某个小区切换机制下得到候选小区配置信息并基于该候选小区配置信息形成RRC重配置信令消息，第一网络设备将第一配置信息连同RRC重配置信令消息发送至终端设备。当终端设备向第一网络设备发送CFRA资源获取请求，第一网络设备将第二配置信息连同PDCCH指令发送至终端设备。同理，由于PDCCH指令和RRC重配置信令消息均为执行对候选小区的TA进行有效性管理所需的内容，所以这种在RRC重配置信令消息中承载第一配置信息，在PDCCH指令中承载第二配置信息的方式同样可以避免额外传输带来的资源浪费。In yet another example, the first configuration information is carried in the RRC reconfiguration signaling message and the second configuration information is carried in the PDCCH instruction. Specifically, when the first network device obtains the candidate cell configuration information under a certain cell switching mechanism and forms an RRC reconfiguration signaling message based on the candidate cell configuration information, the first network device combines the first configuration information with the RRC reconfiguration signaling message. The message is sent to the terminal device. When the terminal device sends a CFRA resource acquisition request to the first network device, the first network device sends the second configuration information together with the PDCCH instruction to the terminal device. Similarly, since both the PDCCH instruction and the RRC reconfiguration signaling message are required to perform validity management of the TA of the candidate cell, the first configuration information is carried in the RRC reconfiguration signaling message, and the first configuration information is carried in the PDCCH instruction. The method of carrying the second configuration information can also avoid the waste of resources caused by additional transmission.
应理解，上述的多种发送第一配置信息及第二配置信息的方式，使得第一网络设备可以根据不同的发送方式发送第一配置信息及第二配置信息，提高第一配置信息及第二配置信息传输的灵活性。It should be understood that the above-mentioned multiple ways of sending the first configuration information and the second configuration information enable the first network device to send the first configuration information and the second configuration information according to different sending ways, thereby improving the efficiency of the first configuration information and the second configuration information. Flexibility in configuring information transfer.
还应理解，第一配置信息和第二配置信息还可以作为同一条独立信令通过第一网络设备发送至终端设备。也可以分别作为一条独立信令通过第一网络设备发送至终端设备，使得提高解析第一配置信息和第二配置信息的效率，具体发送方式本申请不作限定。It should also be understood that the first configuration information and the second configuration information can also be sent to the terminal device through the first network device as the same independent signaling. It can also be sent as an independent signaling to the terminal device through the first network device, so as to improve the efficiency of parsing the first configuration information and the second configuration information. The specific sending method is not limited in this application.
还应理解，当第一配置信息和第二配置信息同时承载在PDCCH指令中或RRC重配置信令消息中时，第一配置信息和第二配置信息还可以作为同一个指示信息承载在PDCCH指令中或RRC重配置信令消息中，该同一个指示信息的具体表现形式本申请不作限定。It should also be understood that when the first configuration information and the second configuration information are carried in the PDCCH instruction or the RRC reconfiguration signaling message at the same time, the first configuration information and the second configuration information can also be carried in the PDCCH instruction as the same indication information. In the RRC reconfiguration signaling message or in the RRC reconfiguration signaling message, the specific expression form of the same indication information is not limited in this application.
基于此，终端设备以第一配置信息和第二配置信息为基础，根据第一指示信息执行对候选小区的TA的有效性管理，具体可以包括：Based on this, the terminal device performs validity management of the TA of the candidate cell based on the first configuration information and the second configuration information and according to the first indication information, which may specifically include:
启动候选小区的TA计时器进行计时，若计时时间达到TA公共更新时长阈值或TA私有更新时长阈值，则触发进行对应候选小区TA的更新。Start the TA timer of the candidate cell for timing. If the timing time reaches the TA public update duration threshold or the TA private update duration threshold, an update of the TA of the corresponding candidate cell is triggered.
由于第一配置信息和第二配置信息具有不同的搭配，所以为了更加清楚地说明终端设备以第一配置信息和第二配置信息为条件执行对候选小区的TA的有效性管理，下面以第一配置信息和第二配置信息的不同搭配为例，对执行对候选小区的TA的有效性管理进行详细介绍。Since the first configuration information and the second configuration information have different combinations, in order to explain more clearly that the terminal device performs validity management of the TA of the candidate cell based on the first configuration information and the second configuration information, the following is the first configuration information. Taking different combinations of the configuration information and the second configuration information as an example, the implementation of effectiveness management of the TA of the candidate cell is introduced in detail.
当第一配置信息中包括候选小区的TA公共有效时长及超过公共有效时长TA失效的信息，第二配置信息中包括候选小区的TA公共更新时长阈值，则终端设备在未超过公共有效时长时启动候选小区的TA计时器进行计时，并在计时时间达到TA公共更新时长阈值时触发进行对应候选小区TA的更新。同理，当第一配置信息中包括对应候选小区的TA私有有效时长及超过私有有效时长对应TA失效的信息，第二配置信息中包括对应候选小区的TA私有更新时长阈值，则终端设备在未超过对应候选小区的TA私有有效时长时启动候选小区的TA计时器进行计时，并在计时时间达到对应候选小区的TA私有更新时长阈值时触发进行对应候选小区TA的更新。When the first configuration information includes the TA public validity period of the candidate cell and the TA failure information when the public validity period is exceeded, and the second configuration information includes the TA public update duration threshold of the candidate cell, then the terminal device starts up when the public validity period has not been exceeded. The TA timer of the candidate cell counts, and when the timing time reaches the TA public update duration threshold, an update of the TA of the corresponding candidate cell is triggered. Similarly, when the first configuration information includes the TA private validity period corresponding to the candidate cell and the information that the TA expires when the private validity period exceeds, and the second configuration information includes the TA private update duration threshold corresponding to the candidate cell, then the terminal device will When the TA private validity period of the corresponding candidate cell is exceeded, the TA timer of the candidate cell is started for timing, and when the timing reaches the TA private update duration threshold of the corresponding candidate cell, an update of the TA of the corresponding candidate cell is triggered.
可以理解的是，若各候选小区的TA私有有效时长及TA私有更新时长阈值是不同的，那么启动各候选小区的TA计时器的时间点可以是不同的，触发进行对应候选小区TA的更新的时间点也可以是不同的。因此，本实施例对由终端设备对候选小区的TA进行有效性管理进行了详细说明，更为具体地介绍了终端设备对候选小区的TA进行有效性管理的步骤。那么当由终端设备对候选小区的TA进行有效性管理时，通过由第一网络设备向终端设备发送第一配置信息和第二配置信息，终端设备就可根据两配置信息触发对候选小区TA的更新，无需在候选小区TA将要失效时触发候选小区TA的更新，提高终端设备更新候选小区TA的及时性。It can be understood that if the TA private valid duration and TA private update duration thresholds of each candidate cell are different, then the time point for starting the TA timer of each candidate cell may be different, triggering the update of the TA of the corresponding candidate cell. The time points can also be different. Therefore, this embodiment provides a detailed description of the terminal device's effectiveness management of the TA of the candidate cell, and more specifically introduces the steps of the terminal device's effectiveness management of the TA of the candidate cell. Then, when the terminal device performs validity management on the TA of the candidate cell, by sending the first configuration information and the second configuration information to the terminal device from the first network device, the terminal device can trigger the validation of the TA of the candidate cell based on the two configuration information. Update, there is no need to trigger the update of the candidate cell TA when the candidate cell TA is about to expire, thereby improving the timeliness of the terminal equipment updating the candidate cell TA.
本实施例中，当触发进行对应候选小区TA的更新，可包括以下实现方式：In this embodiment, when an update of the corresponding candidate cell TA is triggered, the following implementation methods may be included:
一种可能的实现方式是，终端设备向第二网络设备发送CFRA请求，该CFRA请求用于指示第二网络设备获取对应候选小区的当前TA。第二网络设备向终端设备发送CFRA响应，该CFRA响应包括对应候选小区的当前TA。终端设备根据当前TA进行对应候选小区TA的更新。One possible implementation manner is that the terminal device sends a CFRA request to the second network device, where the CFRA request is used to instruct the second network device to obtain the current TA of the corresponding candidate cell. The second network device sends a CFRA response to the terminal device, where the CFRA response includes the current TA corresponding to the candidate cell. The terminal device updates the corresponding candidate cell TA according to the current TA.
其中，候选小区的当前TA为终端设备最新获取到的候选小区的TA。The current TA of the candidate cell is the latest TA of the candidate cell obtained by the terminal device.
应理解，在该实现方式中，终端设备向第二网络设备发送CFRA请求的前提是终端设备已经获取到CFRA资源。该获取到CFRA资源的执行方式与前述获取CFRA资源的方式类似，此处不再赘述。基于此，终端设备依据CFRA资源向第一网络设备发送CFRA请求，并由第二网络设备根据该CFRA请求获取候选小区的当前TA，并将该候选小区的当前TA携带在CFRA响应中，以将候选小区的当前TA发送至终端设备。It should be understood that in this implementation manner, the prerequisite for the terminal device to send the CFRA request to the second network device is that the terminal device has obtained the CFRA resource. The execution method of obtaining the CFRA resource is similar to the aforementioned method of obtaining the CFRA resource, and will not be described again here. Based on this, the terminal device sends a CFRA request to the first network device based on the CFRA resource, and the second network device obtains the current TA of the candidate cell according to the CFRA request, and carries the current TA of the candidate cell in the CFRA response, so as to The current TA of the candidate cell is sent to the terminal device.
那么终端设备基于CFRA响应即可按照当前TA对对应候选小区TA进行更新，具体的更新方式可通过当前TA替换对应候选小区TA来实现，本申请对此不作限定。因此，上述触发进行对应候选小区TA的更新的方法中，终端设备通过向第二网络设备发送CFRA请求，就可以根据CFRA请求获取到最新的当前TA，并可以采用该当前TA对对应候选小区TA进行更新，从而能够顺利得到第二网络设备返回的当前TA，相较于发送新的指令获取当前TA，节省了传输资源。Then the terminal device can update the corresponding candidate cell TA according to the current TA based on the CFRA response. The specific update method can be realized by replacing the corresponding candidate cell TA with the current TA, which is not limited in this application. Therefore, in the above method of triggering the update of the corresponding candidate cell TA, the terminal device can obtain the latest current TA according to the CFRA request by sending a CFRA request to the second network device, and can use the current TA to update the corresponding candidate cell TA. The update is performed so that the current TA returned by the second network device can be successfully obtained. Compared with sending a new instruction to obtain the current TA, transmission resources are saved.
另一种可能的实现方式是，终端设备执行候选小区的当前TA测量过程，并获取候选小区的当前TA，从而根据当前TA进行对应候选小区TA的更新。Another possible implementation is that the terminal device performs the current TA measurement process of the candidate cell and obtains the current TA of the candidate cell, so as to update the corresponding candidate cell TA based on the current TA.
其中，终端设备在执行候选小区的当前TA测量过程时，具体可以同时接收第一网络设备和第二网络设备的信号，并记录下从第一网络设备和第二网络设备接收到信号对应的接收时间，将两接收时间的差值确定为候选小区的当前TA。When performing the current TA measurement process of the candidate cell, the terminal device may receive signals from the first network device and the second network device at the same time, and record the reception corresponding to the signals received from the first network device and the second network device. time, and the difference between the two reception times is determined as the current TA of the candidate cell.
基于此，终端设备获取候选小区的当前TA，并采用当前TA对对应候选小区TA进行更新。因此，上述触发进行对应候选小区TA的更新的方法中，终端设备通过自行测量对应候选小区最新的当前TA，就可以采用该当前TA对对应候选小区TA进行更新，提高获取候选小区的最新TA的效率。Based on this, the terminal device obtains the current TA of the candidate cell, and uses the current TA to update the TA of the corresponding candidate cell. Therefore, in the above method of triggering the update of the TA of the corresponding candidate cell, the terminal device can measure the latest current TA of the corresponding candidate cell by itself, and then use the current TA to update the TA of the corresponding candidate cell, thereby improving the efficiency of obtaining the latest TA of the candidate cell. efficiency.
应理解，本申请可采用两种方式中的一种来触发对候选小区TA的更新，所以有效提高了由终端设备管理时更新候选小区TA的灵活性。It should be understood that this application can use one of two methods to trigger the update of the candidate cell TA, so it effectively improves the flexibility of updating the candidate cell TA when managed by the terminal device.
二、对候选小区的定时提前量TA进行有效性管理的设备为第一网络设备。2. The device that performs validity management on the timing advance TA of the candidate cell is the first network device.
在上述实施例提供的定时提前量管理方法中，在第一网络设备在接收到终端发送的第三指示信息获知终端设备已获取到对应候选小区的TA或接收到终端设备发送的候选小区的TA值之外，为了能够实现第一网络设备对候选小区的TA的有效性管理，还要获取进行有效性管理的相关信息。In the timing advance management method provided in the above embodiment, after the first network device receives the third indication information sent by the terminal, it learns that the terminal device has obtained the TA of the corresponding candidate cell or receives the TA of the candidate cell sent by the terminal device. In addition to the value, in order to realize the effectiveness management of the TA of the candidate cell by the first network device, it is also necessary to obtain relevant information for effectiveness management.
那么进行有效性管理的相关信息可以包括第一配置信息和第二配置信息。Then the relevant information for validity management may include first configuration information and second configuration information.
所以可选地，获取第一配置信息和第二配置信息，具体可以包括：Therefore, optionally, obtaining the first configuration information and the second configuration information may specifically include:
第二网络设备向第一网络设备发送第一配置信息和第二配置信息。The second network device sends the first configuration information and the second configuration information to the first network device.
应理解，此处的第一配置信息和第二配置信息与由终端设备管理对应候选小区的TA时所采用的第一配置信息和第二配置信息类似，此处不再赘述。It should be understood that the first configuration information and the second configuration information here are similar to the first configuration information and the second configuration information used when the terminal device manages the TA corresponding to the candidate cell, and will not be described again here.
还应理解，根据前述的方法，由于第一配置信息和第二配置信息具有多种搭配，所以第一网络设备可以根据多种搭配的第一配置信息和第二配置信息对候选小区的TA进行有效性管理，由此可以提高第一网络设备管理的灵活性。It should also be understood that according to the foregoing method, since the first configuration information and the second configuration information have multiple combinations, the first network device can perform the TA of the candidate cell according to the first configuration information and the second configuration information with multiple combinations. Effectiveness management, thereby improving the flexibility of first network device management.
还应理解，第一配置信息和第二配置信息可以承载在一条独立信令中，由此避免额外传输带来的资源浪费。或者，第一配置信息承载在一条独立信令中且第二配置信息承载在另一条独立信令中，由此提高解析第一配置信息和第二配置信息的效率。It should also be understood that the first configuration information and the second configuration information may be carried in an independent signaling, thereby avoiding resource waste caused by additional transmission. Alternatively, the first configuration information is carried in an independent signaling and the second configuration information is carried in another independent signaling, thereby improving the efficiency of parsing the first configuration information and the second configuration information.
还应理解，本申请提供了两种传输第一配置信息和第二配置信息的方式，可以有效提高传输的第一配置信息和第二配置信息的灵活性。It should also be understood that this application provides two ways of transmitting the first configuration information and the second configuration information, which can effectively improve the flexibility of the transmitted first configuration information and the second configuration information.
基于此，第一网络设备以第一配置信息和第二配置信息为基础，根据第三指示信息对候选小区的TA进行有效性管理，具体可以包括：Based on this, the first network device performs validity management on the TA of the candidate cell based on the first configuration information and the second configuration information and based on the third indication information, which may specifically include:
启动候选小区的TA计时器进行计时，若计时时间达到TA公共更新时长阈值或TA私有更新时长阈值，则触发进行对应候选小区TA的更新。Start the TA timer of the candidate cell for timing. If the timing time reaches the TA public update duration threshold or the TA private update duration threshold, an update of the TA of the corresponding candidate cell is triggered.
换言之，当第一网络设备接收到终端设备发送的第三指示信息，则确定对候选小区的TA进行有效性管理。基于此，第一网络设备根据所获取到的第一配置信息和第二配置信息，在未超过第一配置信息所指示的公共有效时长或对应私有有效时长时启动候选小区的TA计时器进行计时，并在计时时间达到第二配置信息所指示的TA公共更新时长阈值或TA私有更新时长阈值时触发进行对应候选小区TA的更新。因此，本实施例对由第一网络设备对候选小区的TA进行有效性管理进行了详细说明，更为具体地介绍了第一网络设备对候选小区的TA进行有效性管理的步骤。那么当由第一网络设备对候选小区的TA进行有效性管理时，通过由第二网络设备向第一网络设备发送第一配置信息和第二配置信息，第一网络设备就可根据两配置信息触发对候选小区TA的更新，无需在候选小区TA将要失效时触发候选小区TA的更新，提高第一网络设备更新候选小区TA的及时性。In other words, when the first network device receives the third indication information sent by the terminal device, it determines to perform validity management on the TA of the candidate cell. Based on this, the first network device starts the TA timer of the candidate cell for timing according to the obtained first configuration information and the second configuration information when the public valid time period indicated by the first configuration information or the corresponding private valid time period is not exceeded. , and when the timing time reaches the TA public update duration threshold or the TA private update duration threshold indicated by the second configuration information, an update of the corresponding candidate cell TA is triggered. Therefore, this embodiment provides a detailed description of the effectiveness management of the TA of the candidate cell by the first network device, and more specifically introduces the steps of the first network device performing effectiveness management of the TA of the candidate cell. Then when the first network device performs validity management on the TA of the candidate cell, by sending the first configuration information and the second configuration information to the first network device from the second network device, the first network device can use the two configuration information to Triggering the update of the candidate cell TA does not need to trigger the update of the candidate cell TA when the candidate cell TA is about to expire, thereby improving the timeliness of the first network device updating the candidate cell TA.
本实施例中，当触发进行对应候选小区TA的更新，可包括以下实现方式：In this embodiment, when an update of the corresponding candidate cell TA is triggered, the following implementation methods may be included:
一种可能的实现方式是，第一网络设备向终端设备发送PDCCH指令，该PDCCH指令包括随机接入资源指示信息，该随机接入资源指示信息用于指示终端设备通过CFRA请求从第二网络设备获取对应候选小区当前TA。终端设备向第一网络设备发送第四指示信息，该第四指示信息用于指示已更新对应候选小区的TA或更新后的TA值。One possible implementation is that the first network device sends a PDCCH instruction to the terminal device. The PDCCH instruction includes random access resource indication information. The random access resource indication information is used to instruct the terminal device to request from the second network device through CFRA. Obtain the current TA of the corresponding candidate cell. The terminal device sends fourth indication information to the first network device, where the fourth indication information is used to indicate that the TA of the corresponding candidate cell or the updated TA value has been updated.
其中，第四指示信息为指示终端设备已经完成对应候选小区的TA更新的相关信息。The fourth indication information is relevant information indicating that the terminal equipment has completed the TA update of the corresponding candidate cell.
应理解，在该实现方式中，当第一网络设备决定触发进行对应候选小区TA的更新，向终端设备发送包括随机接入资源指示信息的PDCCH指令，使得终端设备在接收到该PDCCH指令之后依据CFRA资源向第二网络设备发送CFRA请求，从而获取对应候选小区当前TA并采用该当前TA完成对应候选小区TA的更新。基于此，终端设备在完成对应候选小区TA的更新之后，根据更新后的候选小区TA形成第四指示信息，并将该第四指示信息发送至第一网络设备。It should be understood that in this implementation, when the first network device decides to trigger the update of the corresponding candidate cell TA, it sends a PDCCH instruction including random access resource indication information to the terminal device, so that the terminal device receives the PDCCH instruction according to The CFRA resource sends a CFRA request to the second network device, thereby obtaining the current TA of the corresponding candidate cell and using the current TA to complete the update of the TA of the corresponding candidate cell. Based on this, after completing the update of the corresponding candidate cell TA, the terminal device forms fourth indication information based on the updated candidate cell TA, and sends the fourth indication information to the first network device.
那么在终端设备形成第四指示信息时，具体可以根据第一配置信息和第二配置信息的搭配形成对应的第四指示信息：Then when the terminal device forms the fourth indication information, the corresponding fourth indication information may be formed based on the combination of the first configuration information and the second configuration information:
若第一配置信息和第二配置信息的搭配为第一配置信息中包括候选小区的TA公共有效时长及超过公共有效时长TA失效的信息，第二配置信息中包括候选小区的TA公共更新时长阈值，说明各个更新后的候选小区的TA值相同，则直接按照该更新后的候选小区的TA值或者已更新候选小区的TA形成第四指示信息。若第一配置信息和第二配置信息的搭配为第一配置信息中包括对应候选小区的TA私有有效时长及超过私有有效时长对应TA失效的信息，第二配置信息中包括对应候选小区的TA私有更新时长阈值，说明存在不同的更新后的候选小区的TA值，则按照各个更新后的候选小区的TA值或者各个已更新候选小区的TA形成第四指示信息。If the combination of the first configuration information and the second configuration information is that the first configuration information includes the TA public validity period of the candidate cell and the TA failure information exceeding the public validity period, the second configuration information includes the TA public update duration threshold of the candidate cell. , indicating that the TA values of each updated candidate cell are the same, then the fourth indication information is directly formed according to the TA value of the updated candidate cell or the TA of the updated candidate cell. If the combination of the first configuration information and the second configuration information is that the first configuration information includes the TA private validity period corresponding to the candidate cell and the information corresponding to the TA failure exceeding the private validity period, the second configuration information includes the TA private validity period corresponding to the candidate cell. The update duration threshold indicates that there are different updated TA values of candidate cells, and the fourth indication information is formed according to the TA value of each updated candidate cell or the TA of each updated candidate cell.
在一种示例中，当终端设备按照各个更新后的候选小区的TA值形成第四指示信息，则可将各个更新后的候选小区的TA值与对应候选小区标识进行关联，例如，建立更新后的候选小区的TA值及其对应候选小区标识之间的映射关系，以按照关联结果形成第四指示信息。In one example, when the terminal device forms the fourth indication information according to the TA value of each updated candidate cell, the TA value of each updated candidate cell can be associated with the corresponding candidate cell identifier, for example, the updated The mapping relationship between the TA value of the candidate cell and its corresponding candidate cell identifier is used to form fourth indication information according to the association result.
在另一种示例中，当终端设备按照各个已更新候选小区的TA形成第四指示信息，则可根据各个已更新候选小区的TA的结果形成一串特定字段，将候选小区对应的特定字段与对应候选小区标识进行关联，例如，建立候选小区对应的特定字段及其对应候选小区标识之间的映射关系，以按照关联结果形成第四指示信息。其中，特定字段表示已经更新候选小区的TA。In another example, when the terminal device forms the fourth indication information according to the TA of each updated candidate cell, it can form a series of specific fields according to the results of the TA of each updated candidate cell, and combine the specific fields corresponding to the candidate cells with Correlating the candidate cell identifiers, for example, establishing a mapping relationship between specific fields corresponding to the candidate cells and their corresponding candidate cell identifiers, so as to form fourth indication information according to the association result. Among them, the specific field indicates that the TA of the candidate cell has been updated.
可以理解的是，映射关系的表示方式可以为映射表格的形式或者其他形式，本实施例中对此不做限定。It can be understood that the mapping relationship can be expressed in the form of a mapping table or other forms, which is not limited in this embodiment.
应理解，当候选小区为多个，则在按照各个更新后的候选小区的TA值或者各个已更新候选小区的TA形成第四指示信息时可以按照更新后的全部候选小区的TA值形成第四指示信息。或者，可以按照更新后的全部候选小区的TA的结果形成第四指示信息。或者，可以按照更新后的一部分候选小区的TA值以及更新后的另一部分候选小区的TA的结果形成第四指示信息。第四指示信息的具体形式本申请不作限定。因此，上述触发进行对应候选小区TA的更新的方法中，第一网络设备通过向终端设备发送PDCCH指令，使得终端设备可以基于PDCCH指令中的CFRA资源向第一网络设备发送CFRA请求，并使得终端设备在获取到最新的当前TA之后可以采用该当前TA对对应候选小区TA进行更新，从而使得终端设备可以向第一网络设备发送更新结果，由此使得第一网络设备能够在终端设备得到第二网络设备返回的当前TA之后顺利获取候选小区的最新TA，相较于在终端设备发送新的指令得到当前TA之后获取候选小区的最新TA，节省了传输资源，并提高了第一网络设备获取候选小区的最新TA的及时性。It should be understood that when there are multiple candidate cells, when the fourth indication information is formed according to the TA value of each updated candidate cell or the TA of each updated candidate cell, the fourth indication information may be formed according to the updated TA values of all candidate cells. Instructions. Alternatively, the fourth indication information may be formed according to the updated TA results of all candidate cells. Alternatively, the fourth indication information may be formed according to the result of updated TA values of a part of the candidate cells and updated TA values of another part of the candidate cells. The specific form of the fourth instruction information is not limited in this application. Therefore, in the above method of triggering the update of the corresponding candidate cell TA, the first network device sends a PDCCH instruction to the terminal device, so that the terminal device can send a CFRA request to the first network device based on the CFRA resource in the PDCCH instruction, and the terminal device After obtaining the latest current TA, the device can use the current TA to update the corresponding candidate cell TA, so that the terminal device can send the update result to the first network device, thereby enabling the first network device to obtain the second After the current TA returned by the network device, the latest TA of the candidate cell is successfully obtained. Compared with obtaining the latest TA of the candidate cell after the terminal device sends a new instruction to obtain the current TA, transmission resources are saved and the first network device improves the efficiency of obtaining candidates. The latest TA of the community is timely.
另一种可能的实现方式是，第一网络设备向终端设备发送测量指令，该测量指令用于指示终端设备执行候选小区的当前TA测量过程。终端设备向第一网络设备发送第四指示信息。Another possible implementation is that the first network device sends a measurement instruction to the terminal device, where the measurement instruction is used to instruct the terminal device to perform the current TA measurement process of the candidate cell. The terminal device sends fourth instruction information to the first network device.
应理解，在该实现方式中，当第一网络设备决定触发进行对应候选小区TA的更新，向终端设备发送测量指令，使得终端设备根据该测量指令执行候选小区的当前TA测量过程。基于此，终端设备根据测量得到的当前TA对候选小区TA进行更新，并根据更新后的候选小区TA形成第四指示信息，以将该第四指示信息发送至第一网络设备。It should be understood that in this implementation, when the first network device decides to trigger an update of the TA corresponding to the candidate cell, it sends a measurement instruction to the terminal device, so that the terminal device performs the current TA measurement process of the candidate cell according to the measurement instruction. Based on this, the terminal device updates the candidate cell TA according to the measured current TA, and forms fourth indication information according to the updated candidate cell TA, so as to send the fourth indication information to the first network device.
还应理解，此处形成第四指示信息的方式与上一个实现方式中形成第四指示信息的方式类似，此处不再赘述。因此，上述触发进行对应候选小区TA的更新的方法中，第一网络设备通过向终端设备发送测量指令，使得终端设备可以自行测量对应候选小区最新的当前TA，并使得终端设备可以采用该当前TA对对应候选小区TA进行更新，从而使得终端设备可以向第一网络设备发送更新结果。由此使得第一网络设备能够在终端设备自行得到当前TA之后获取候选小区的最新TA，提高第一网络设备获知候选小区最新TA的效率。It should also be understood that the manner in which the fourth indication information is formed here is similar to the manner in which the fourth indication information is formed in the previous implementation, and will not be described again here. Therefore, in the above method of triggering the update of the TA corresponding to the candidate cell, the first network device sends a measurement instruction to the terminal device, so that the terminal device can measure the latest current TA corresponding to the candidate cell by itself, and the terminal device can adopt the current TA. The corresponding candidate cell TA is updated, so that the terminal device can send the update result to the first network device. This enables the first network device to obtain the latest TA of the candidate cell after the terminal device obtains the current TA by itself, thereby improving the efficiency of the first network device in obtaining the latest TA of the candidate cell.
应理解，本申请可采用两种方式中的一种来触发对候选小区TA的更新，所以有效提高了由第一网络设备管理时更新候选小区TA的灵活性。It should be understood that this application can use one of two methods to trigger the update of the candidate cell TA, thus effectively improving the flexibility of updating the candidate cell TA when managed by the first network device.
三、对候选小区的定时提前量TA进行有效性管理的设备为第二网络设备。3. The device that performs validity management on the timing advance TA of the candidate cell is the second network device.
在上述实施例提供的定时提前量管理方法中，在第二网络设备在接收到终端发送的第三指示信息获知终端设备已获取到对应候选小区的TA或接收到终端设备发送的候选小区的TA值之外，为了能够实现第二网络设备对候选小区的TA的有效性管理，还要获取进行有效性管理的相关信息。In the timing advance management method provided in the above embodiment, after the second network device receives the third indication information sent by the terminal, it learns that the terminal device has obtained the TA of the corresponding candidate cell or receives the TA of the candidate cell sent by the terminal device. In addition to the value, in order to realize the effectiveness management of the TA of the candidate cell by the second network device, it is also necessary to obtain relevant information for effectiveness management.
那么进行有效性管理的相关信息可以包括第一配置信息和第二配置信息。Then the relevant information for validity management may include first configuration information and second configuration information.
基于此，第二网络设备获取对应候选小区的第一配置信息和第二配置信息。Based on this, the second network device obtains the first configuration information and the second configuration information corresponding to the candidate cell.
应理解，此处的第一配置信息和第二配置信息与由终端设备或第一网络设备管理对应候选小区的TA时所采用的第一配置信息和第二配置信息类似，此处不再赘述。It should be understood that the first configuration information and the second configuration information here are similar to the first configuration information and the second configuration information used when the terminal device or the first network device manages the TA of the corresponding candidate cell, and will not be described again here. .
还应理解，如前述的方法，第一配置信息和第二配置信息具有多种搭配，第二网络设备可以根据多种搭配的第一配置信息和第二配置信息对候选小区的TA进行有效性管理，由此可以提高第二网络设备管理的灵活性。It should also be understood that, as in the foregoing method, the first configuration information and the second configuration information have multiple combinations, and the second network device can validate the TA of the candidate cell based on the multiple combinations of the first configuration information and the second configuration information. management, thereby improving the flexibility of management of the second network device.
在此之后，第一网络设备以第一配置信息和第二配置信息为基础，根据第三指示信息对候选小区的TA进行有效性管理，具体可以包括：After that, the first network device performs validity management on the TA of the candidate cell based on the first configuration information and the second configuration information and the third indication information, which may specifically include:
启动TA计时器进行计时，若计时时间达到TA公共更新时长阈值或TA私有更新时长阈值，则触发进行对应候选小区TA的更新。Start the TA timer for timing. If the timing reaches the TA public update duration threshold or the TA private update duration threshold, the TA update of the corresponding candidate cell is triggered.
换言之，当第二网络设备接收到终端设备发送的第三指示信息，则确定对候选小区的TA进行有效性管理。基于此，第二网络设备获取所控制的对应候选小区的第一配置信息和第二配置信息，并在未超过第一配置信息所指示的公共有效时长或对应私有有效时长时启动对应候选小区的TA计时器进行计时，并在计时时间达到第二配置信息所指示的TA公共更新时长阈值或TA私有更新时长阈值时触发进行对应候选小区TA的更新。因此，本实施例对由第二网络设备对候选小区的TA进行有效性管理进行了详细说明，更为具体地介绍了第二网络设备对候选小区的TA进行有效性管理的步骤。那么当由第二网络设备对候选小区的TA进行有效性管理时，通过获取第一配置信息和第二配置信息，第二网络设备就可根据两配置信息触发对候选小区TA的更新，无需在候选小区TA将要失效时触发候选小区TA的更新，提高第二网络设备更新候选小区TA的及时性。In other words, when the second network device receives the third indication information sent by the terminal device, it determines to perform validity management on the TA of the candidate cell. Based on this, the second network device obtains the first configuration information and the second configuration information of the controlled corresponding candidate cell, and starts the corresponding candidate cell when the public valid time period indicated by the first configuration information or the corresponding private valid time period is not exceeded. The TA timer counts, and when the timing reaches the TA public update duration threshold or the TA private update duration threshold indicated by the second configuration information, an update of the corresponding candidate cell TA is triggered. Therefore, this embodiment provides a detailed description of the effectiveness management of the TA of the candidate cell by the second network device, and more specifically introduces the steps for the second network device to perform effectiveness management of the TA of the candidate cell. Then, when the second network device performs validity management on the TA of the candidate cell, by obtaining the first configuration information and the second configuration information, the second network device can trigger the update of the TA of the candidate cell based on the two configuration information, without the need to When the candidate cell TA is about to expire, the update of the candidate cell TA is triggered, thereby improving the timeliness in which the second network device updates the candidate cell TA.
本实施例中，当触发进行对应候选小区TA的更新，可包括以下实现方式：In this embodiment, when an update of the corresponding candidate cell TA is triggered, the following implementation methods may be included:
一种可能的实现方式是，第二网络设备向第一网络设备发送第一消息，该第一消息用于指示第一网络设备向终端设备发送PDCCH指令。终端设备向第二网络设备发送CFRA请求，该CFRA请求用于指示第二网络设备获取对应候选小区的当前TA。第二网络设备向终端设备发送CFRA响应，该CFRA响应包括对应候选小区的当前TA。终端设备向第二网络设备发送第四指示信息，该第四指示信息用于指示已更新对应候选小区的TA或更新后的TA值。One possible implementation manner is that the second network device sends a first message to the first network device, where the first message is used to instruct the first network device to send a PDCCH instruction to the terminal device. The terminal device sends a CFRA request to the second network device, where the CFRA request is used to instruct the second network device to obtain the current TA of the corresponding candidate cell. The second network device sends a CFRA response to the terminal device, where the CFRA response includes the current TA corresponding to the candidate cell. The terminal device sends fourth indication information to the second network device, where the fourth indication information is used to indicate that the TA of the corresponding candidate cell or the updated TA value has been updated.
其中，第一消息为表征向终端设备发送PDCCH指令的指示消息。例如，第一消息可以为表征“向终端设备发送PDCCH指令”的标识、索引、编号等指示消息，也可以为“向终端设备发送PDCCH指令”的字段，本申请对第一消息的具体表现形式不作限定。The first message is an instruction message representing sending a PDCCH instruction to the terminal equipment. For example, the first message can be an indication message such as an identification, index, number, etc. that represents "send a PDCCH instruction to the terminal equipment", or it can also be a field of "send a PDCCH instruction to the terminal equipment". This application describes the specific form of the first message. Not limited.
应理解，在该实现方式中，当第二网络设备决定触发进行对应候选小区TA的更新，向第一网络设备发送第一消息，使得第一网络设备根据第一消息指示的内容向终端设备发送PDCCH指令，进而使得终端设备依据该PDCCH指令中的CFRA资源向第二网络设备发送CFRA请求。那么第二网络设备在接收到该CFRA请求之后，就获取所控制的候选小区的当前TA，并将其携带在CFRA响应中，以将候选小区的当前TA发送至终端设备。It should be understood that in this implementation, when the second network device decides to trigger the update of the corresponding candidate cell TA, it sends the first message to the first network device, so that the first network device sends the message to the terminal device according to the content indicated by the first message. PDCCH instruction, thereby causing the terminal device to send a CFRA request to the second network device according to the CFRA resource in the PDCCH instruction. Then, after receiving the CFRA request, the second network device obtains the current TA of the controlled candidate cell and carries it in the CFRA response, so as to send the current TA of the candidate cell to the terminal device.
基于此，终端设备通过CFRA响应获取候选小区的当前TA，并采用当前TA对对应候选小区的TA进行更新，并根据更新后的候选小区的TA形成第四指示信息，并将其发送至第二网络设备。因此，上述触发进行对应候选小区TA的更新的方法中，第二网络设备通过向第一网络设备发送第一消息，使得第一网络设备可以根据该第一消息向终端设备发送PDCCH指令，并使得终端设备可以基于PDCCH指令中的CFRA资源向第一网络设备发送CFRA请求，从而使得终端设备在获取到最新的当前TA之后可以采用该当前TA对对应候选小区TA进行更新，进而使得终端设备可以向第二网络设备发送更新结果，由此使得第二网络设备能够在终端设备得到返回的当前TA之后顺利获取候选小区的最新TA，相较于在终端设备发送新的指令得到当前TA之后获取候选小区的最新TA，节省了传输资源，并提高了第二网络设备获取候选小区的最新TA的及时性。Based on this, the terminal device obtains the current TA of the candidate cell through the CFRA response, uses the current TA to update the TA of the corresponding candidate cell, and forms the fourth indication information based on the updated TA of the candidate cell, and sends it to the second Internet equipment. Therefore, in the above method of triggering the update of the corresponding candidate cell TA, the second network device sends a first message to the first network device, so that the first network device can send a PDCCH instruction to the terminal device according to the first message, and causes The terminal device can send a CFRA request to the first network device based on the CFRA resource in the PDCCH instruction, so that after obtaining the latest current TA, the terminal device can use the current TA to update the corresponding candidate cell TA, so that the terminal device can update the corresponding candidate cell TA. The second network device sends the update result, thereby enabling the second network device to successfully obtain the latest TA of the candidate cell after the terminal device obtains the returned current TA. Compared with obtaining the candidate cell after the terminal device sends a new instruction to obtain the current TA, The latest TA of the candidate cell saves transmission resources and improves the timeliness in which the second network device obtains the latest TA of the candidate cell.
另一种可能的实现方式是，第二网络设备向第一网络设备发送第二消息，该第二消息用于指示第一网络设备向终端设备发送测量指令。终端设备向第二网络设备发送第四指示信息。Another possible implementation is that the second network device sends a second message to the first network device, where the second message is used to instruct the first network device to send a measurement instruction to the terminal device. The terminal device sends fourth indication information to the second network device.
其中，第二消息为表征向终端设备发送测量指令的指示消息。例如，第二消息可以为表征“向终端设备发送测量指令”的标识、索引、编号等指示消息，也可以为“向终端设备发送测量指令”的字段，本申请对第二消息的具体表现形式不作限定。The second message is an instruction message representing sending a measurement instruction to the terminal device. For example, the second message can be an indication message such as an identification, index, number, etc. that represents "send a measurement instruction to the terminal device", or it can also be a field of "send a measurement instruction to the terminal device". This application describes the specific form of the second message. Not limited.
应理解，在该实现方式中，当第二网络设备决定触发进行对应候选小区TA的更新，向第一网络设备发送第二消息，使得第一网络设备根据该第二消息向终端设备发送测量指令，进而使得终端设备根据该测量指令执行候选小区的当前TA测量过程。基于此，终端设备根据测量得到的当前TA对候选小区TA进行更新，并根据更新后的候选小区TA形成第四指示信息，以将该第四指示信息发送至第一网络设备。因此，上述触发进行对应候选小区TA的更新的方法中，第二网络设备通过向第一网络设备发送第二消息，使得第一网络设备可以根据该第二消息向终端设备发送测量指令，并使得终端设备可以自行测量对应候选小区最新的当前TA，从而使得终端设备可以采用该当前TA对对应候选小区TA进行更新，进而使得终端设备可以向第二网络设备发送更新结果。由此使得第二网络设备能够在终端设备自行得到当前TA之后获取候选小区的最新TA，提高第二网络设备获知候选小区最新TA的效率。It should be understood that in this implementation, when the second network device decides to trigger the update of the corresponding candidate cell TA, it sends a second message to the first network device, so that the first network device sends a measurement instruction to the terminal device according to the second message. , thereby causing the terminal equipment to perform the current TA measurement process of the candidate cell according to the measurement instruction. Based on this, the terminal device updates the candidate cell TA according to the measured current TA, and forms fourth indication information according to the updated candidate cell TA, so as to send the fourth indication information to the first network device. Therefore, in the above method of triggering the update of the corresponding candidate cell TA, the second network device sends a second message to the first network device, so that the first network device can send a measurement instruction to the terminal device according to the second message, and causes The terminal device can measure the latest current TA of the corresponding candidate cell by itself, so that the terminal device can use the current TA to update the TA of the corresponding candidate cell, and then the terminal device can send the update result to the second network device. This enables the second network device to obtain the latest TA of the candidate cell after the terminal device obtains the current TA by itself, thereby improving the efficiency of the second network device in obtaining the latest TA of the candidate cell.
应理解，本申请可采用两种方式中的一种来触发对候选小区TA的更新，所以有效提高了由第二网络设备管理时更新候选小区TA的灵活性。It should be understood that this application can use one of two methods to trigger the update of the candidate cell TA, thus effectively improving the flexibility of updating the candidate cell TA when managed by the second network device.
在本申请的方法中，对候选小区的TA进行有效性管理的目的是促使终端设备能够根据有效的目标小区的TA对目标小区执行切换。所以对根据有效的目标小区的TA对目标小区执行切换的方式进行说明。In the method of the present application, the purpose of performing validity management on the TA of the candidate cell is to enable the terminal device to perform handover to the target cell based on the valid TA of the target cell. Therefore, the method of performing handover on the target cell based on the valid TA of the target cell will be described.
首先，由第一网络设备向第二网络设备发送第三消息，该第三消息用于指示确定第二网络设备管理的目标小区TA是否有效。并由第二网络设备向第一网络设备发送第四消息，该第四消息包括目标小区TA是否有效的信息，该目标小区TA是否有效信息用于指示第一网络设备向终端设备发送的MAC CE信令中是否包括目标小区TA值。First, the first network device sends a third message to the second network device, where the third message is used to indicate whether the target cell TA managed by the second network device is valid. And the second network device sends a fourth message to the first network device. The fourth message includes information about whether the target cell TA is valid. The information about whether the target cell TA is valid is used to indicate the MAC CE sent by the first network device to the terminal device. Whether the target cell TA value is included in the signaling.
其中，第三消息为表征确定所管理的目标小区TA是否有效的指示消息。第四消息为表征目标小区TA是否有效的指示信息。例如，第三消息可以为表征“确定所管理的目标小区TA是否有效”的标识、索引、编号等指示消息，也可以为“确定所管理的目标小区TA是否有效”的字段。第四消息可以为表征“目标小区TA有效”或“目标小区TA无效”的标识、索引、编号等指示信息，也可以为“目标小区TA有效”或“目标小区TA无效”的字段。本申请对第三消息和第四消息的具体表现形式不作限定。The third message is an indication message indicating whether the managed target cell TA is valid. The fourth message is indication information indicating whether the target cell TA is valid. For example, the third message may be an indication message indicating "determining whether the managed target cell TA is valid", or may be a field "determining whether the managed target cell TA is valid". The fourth message may be indication information such as identification, index, and number indicating "Target cell TA is valid" or "Target cell TA is invalid", or may be a field of "Target cell TA is valid" or "Target cell TA is invalid". This application does not limit the specific expression forms of the third message and the fourth message.
应理解，终端设备根据有效的目标小区的TA对目标小区执行切换的前提是接收到第一网络设备发送的MAC CE信令。所以第一网络设备向第二网络设备发送第三消息，使得第二网络设备根据该第三消息确定所控制的目标小区的TA是否有效，并根据是否有效的结果形成第四消息，以将目标小区的TA是否有效的结果告知第一网络设备。因此，第二网络设备通过接收第一网络设备发送的确定目标小区的TA有效性的指令，使得第二网络设备可以及时获知目标小区的TA有效性，并可以及时将目标小区的TA有效性的结果告知第一网络设备。It should be understood that the prerequisite for the terminal device to perform handover to the target cell according to the valid TA of the target cell is to receive the MAC CE signaling sent by the first network device. Therefore, the first network device sends a third message to the second network device, so that the second network device determines whether the TA of the controlled target cell is valid based on the third message, and forms a fourth message based on the result of whether it is valid, so as to transfer the target The result of whether the TA of the cell is valid is notified to the first network device. Therefore, by receiving the instruction sent by the first network device to determine the TA validity of the target cell, the second network device can learn the TA validity of the target cell in time, and can timely update the TA validity of the target cell. The result is notified to the first network device.
那么第一网络设备在根据第四消息确定目标小区TA是否有效的信息之后，存在以下两种情况：Then, after the first network device determines whether the target cell TA is valid based on the fourth message, the following two situations exist:
一种可能的情况是，若第一网络设备确定存在有效的目标小区TA，则第一网络设备在MAC CE信令中携带目标小区TA值，并向终端设备发送MAC CE信令，该MAC CE信令用于指示终端设备向目标小区对应的第二网络设备发送切换指示。One possible situation is that if the first network device determines that there is a valid target cell TA, the first network device carries the target cell TA value in the MAC CE signaling and sends the MAC CE signaling to the terminal device. The MAC CE The signaling is used to instruct the terminal device to send a handover instruction to the second network device corresponding to the target cell.
应理解，当存在有效的目标小区TA时，则终端设备就可依据有效的目标小区TA直接对目标小区执行切换。因此，第一网络设备在确定存在有效的目标小区TA时在MAC CE信令中携带目标小区TA值，以指示终端设备向目标小区对应的第二网络设备发送切换指示。It should be understood that when there is a valid target cell TA, the terminal device can directly perform handover to the target cell based on the valid target cell TA. Therefore, when determining that there is a valid target cell TA, the first network device carries the target cell TA value in the MAC CE signaling to instruct the terminal device to send a handover instruction to the second network device corresponding to the target cell.
另一种可能的情况是，若第一网络设备确定不存在有效的目标小区TA，则第一网络设备在MAC CE信令中不携带目标小区TA值，并向终端设备发送MAC CE信令，该MAC CE信令用于指示终端设备与目标小区对应的第二网络设备执行上行同步过程。Another possible situation is that if the first network device determines that there is no valid target cell TA, the first network device does not carry the target cell TA value in the MAC CE signaling and sends the MAC CE signaling to the terminal device. The MAC CE signaling is used to instruct the terminal device to perform an uplink synchronization process with the second network device corresponding to the target cell.
应理解，当终端设备确定不存在有效的目标小区TA时，则终端设备无法执行切换，需要再次确定目标小区的TA。因此，第一网络设备在确定不存在有效的目标小区TA时不在MAC CE信令中携带目标小区TA值，以指示终端设备与目标小区对应的第二网络设备执行上行同步过程，从而再次确定目标小区的TA。因此，第一网络设备通过获知目标小区的TA有效性的结果，就可以在确定有效时在MAC CE信令中携带目标小区TA值，从而指示终端设备发起切换。并可以在确定无效时在MAC CE信令中不携带目标小区TA值，从而指示终端设备与目标小区执行上行同步过程，提高指示的准确性。It should be understood that when the terminal device determines that there is no valid target cell TA, the terminal device cannot perform handover and needs to determine the TA of the target cell again. Therefore, when the first network device determines that there is no valid target cell TA, it does not carry the target cell TA value in the MAC CE signaling to instruct the terminal device to perform an uplink synchronization process with the second network device corresponding to the target cell, thereby determining the target again. The TA of the community. Therefore, by learning the result of the TA validity of the target cell, the first network device can carry the TA value of the target cell in the MAC CE signaling when it is determined to be valid, thereby instructing the terminal device to initiate a handover. And when it is determined to be invalid, the TA value of the target cell may not be carried in the MAC CE signaling, thereby instructing the terminal equipment to perform an uplink synchronization process with the target cell, thereby improving the accuracy of the instruction.
基于此，终端设备根据该MAC CE信令确定后续所执行的动作。Based on this, the terminal device determines subsequent actions to be performed according to the MAC CE signaling.
需要说明的是，由于当终端设备对候选小区的TA进行有效性管理时终端设备可以直接获知目标小区TA有效或无效的结果，且终端设备获知的时间在第一网络设备获知的时间之后。因此，如果当前管理情况为由终端设备对候选小区的TA进行有效性管理，则终端设备根据该MAC CE信令确定后续所执行的动作，具体可以包括：It should be noted that when the terminal device performs validity management on the TA of the candidate cell, the terminal device can directly learn whether the TA of the target cell is valid or invalid, and the time the terminal device learns is after the time the first network device learns. Therefore, if the current management situation is that the terminal device performs validity management on the TA of the candidate cell, the terminal device determines the subsequent actions to be performed based on the MAC CE signaling, which may specifically include:
若终端设备确定存在有效的目标小区TA，则直接向目标小区对应的第二网络设备发送切换指示，该切换指示用于指示切换到目标小区。若终端设备确定不存在有效的目标小区TA，则进一步确定MAC CE信令中是否包括目标小区TA值，并在确定MAC CE信令中包括目标小区TA值时向目标小区对应的第二网络设备发送切换指示，在确定MAC CE信令中不包括目标小区TA值，则根据目标小区TA无效的结果与目标小区执行上行同步过程。If the terminal device determines that there is a valid target cell TA, it directly sends a handover instruction to the second network device corresponding to the target cell, where the handover instruction is used to instruct switching to the target cell. If the terminal device determines that there is no valid target cell TA, it further determines whether the MAC CE signaling includes the target cell TA value, and when it determines that the MAC CE signaling includes the target cell TA value, it sends a message to the second network device corresponding to the target cell. After sending the handover instruction and confirming that the MAC CE signaling does not include the TA value of the target cell, the uplink synchronization process is performed with the target cell based on the result that the TA of the target cell is invalid.
需要说明的是，终端设备可以根据目标小区对应的TA计时器确定是否存在有效的目标小区TA。具体地，当目标小区对应的TA计时器未超时，则确定存在有效的目标小区TA。当目标小区对应的TA计时器超时，则确定不存在有效的目标小区TA。It should be noted that the terminal device can determine whether there is a valid target cell TA according to the TA timer corresponding to the target cell. Specifically, when the TA timer corresponding to the target cell has not expired, it is determined that there is a valid target cell TA. When the TA timer corresponding to the target cell times out, it is determined that there is no valid target cell TA.
应理解，该目标小区对应的TA计时器未超时所对应的情况存在以下两种：It should be understood that there are two situations where the TA timer corresponding to the target cell has not expired:
（1）目标小区的TA未发生更新且计时时长未超过目标小区的TA公共有效时长或私有有效时长。(1) The TA of the target cell has not been updated and the timing does not exceed the public effective time or private effective time of the TA of the target cell.
（2）目标小区的TA已发生更新且目标小区对应的TA计时器已重启，且重启后目标小区的TA未发生更新且计时时长超过目标小区的TA公共有效时长或私有有效时长。(2) The TA of the target cell has been updated and the TA timer corresponding to the target cell has been restarted. After the restart, the TA of the target cell has not been updated and the timing exceeds the TA public valid time or private valid time of the target cell.
还应理解，上述对目标小区对应的TA计时器未超时的情况的说明仅为举例，不应对本申请构成任何限定。It should also be understood that the above description of the situation where the TA timer corresponding to the target cell has not expired is only an example and should not constitute any limitation on the present application.
还应理解，当终端设备指示切换到目标小区，说明目标小区TA有效，则可以直接向目标小区发送一个指示来实现切换。其中，该指示可以为RRC重配置信令完成消息，或可以为任意一个上行数据，该指示的具体内容本申请不作限定。当终端设备与目标小区执行上行同步过程，说明目标小区TA无效，则可以向第二网络设备发送CFRA请求，从而再次获取目标小区TA来实现上行同步过程。其中，该CFRA请求可以包括目标小区标识，该目标小区标识可以为表征目标小区身份的任意标识，如目标小区的名称、编号等，本申请对此不作限定。因此，在终端设备管理候选小区TA的情况下，终端设备通过确认当前是否存在有效的目标小区TA，就可在确定存在时直接向目标小区发起切换，并可在确定不存在时进一步确定MACCE信令中是否包括目标小区TA值，从而在确定包括时直接向目标小区发起切换，在确定不包括时与目标小区执行上行同步过程，提高切换的成功率。It should also be understood that when the terminal equipment instructs to switch to the target cell, indicating that the target cell TA is valid, it can directly send an instruction to the target cell to implement the switch. The indication may be an RRC reconfiguration signaling completion message, or may be any uplink data. The specific content of the indication is not limited in this application. When the terminal device performs the uplink synchronization process with the target cell, indicating that the target cell TA is invalid, a CFRA request can be sent to the second network device to obtain the target cell TA again to implement the uplink synchronization process. The CFRA request may include a target cell identifier, and the target cell identifier may be any identifier representing the identity of the target cell, such as the name and number of the target cell, which is not limited in this application. Therefore, when the terminal device manages the candidate cell TA, the terminal device can directly initiate a handover to the target cell when it is determined that there is a valid target cell TA by confirming whether it currently exists, and can further determine the MACCE information when it is determined that it does not exist. Whether the TA value of the target cell is included in the order, so that when it is determined to be included, a handover is directly initiated to the target cell, and when it is determined not to be included, the uplink synchronization process is performed with the target cell to improve the success rate of the handover.
如果当前管理情况为由第一网络设备或第二网络设备对候选小区的TA进行有效性管理，则终端设备根据该MAC CE信令确定后续所执行的动作，具体可以包括：If the current management situation is that the first network device or the second network device performs validity management on the TA of the candidate cell, the terminal device determines the subsequent action to be performed based on the MAC CE signaling, which may specifically include:
若终端设备确定MAC CE信令中包括目标小区TA值，则直接向目标小区对应的第二网络设备发送切换指示。若终端设备确定MAC CE信令中不包括目标小区TA值，则与目标小区执行包括CFRA的上行同步过程。因此，在第一网络设备或第二网络设备管理候选小区TA的情况下，终端设备通过确定MAC CE信令中是否包括目标小区TA值，就可在确定包括时直接向目标小区发起切换，在确定不包括时与目标小区执行上行同步过程，进一步提高切换的成功率。If the terminal device determines that the MAC CE signaling includes the TA value of the target cell, it directly sends a handover instruction to the second network device corresponding to the target cell. If the terminal equipment determines that the MAC CE signaling does not include the TA value of the target cell, it performs an uplink synchronization process including CFRA with the target cell. Therefore, when the first network device or the second network device manages the candidate cell TA, the terminal device can directly initiate a handover to the target cell when determining whether the TA value of the target cell is included in the MAC CE signaling. When it is determined that it is not included, the uplink synchronization process is performed with the target cell to further improve the success rate of handover.
下面分别以对候选小区的定时提前量TA进行有效性管理的设备为终端设备、第一网络设备和第二网络设备时，对候选小区的TA进行有效性管理的方案以信令交互图的方式进行详细介绍。In the following, when the devices that perform validity management on the timing advance TA of the candidate cell are respectively a terminal device, a first network device, and a second network device, the solution for performing validity management on the TA of the candidate cell is in the form of a signaling interaction diagram.
