技术领域technical field

本发明涉及通信技术领域，尤其涉及一种数据调度方法、基站及系统。The present invention relates to the field of communication technologies, and in particular, to a data scheduling method, base station and system.

背景技术Background technique

随着无线通信的快速发展，人们早已不满足仅限于人与人的通信，物联网(Internet Of Things，IOT)技术应运而生。机器与机器之间的通信(Machine to Machine，M2M)，是机器与机器之间通过无线网络互相传递信息和数据的简称，是IOT发展的重要方向。M2M设备多是比较小巧、电池供电的系统，如智能抄表系统，需要对水、电煤气等使用情况进行周期性监测并上报。With the rapid development of wireless communication, people are no longer satisfied with the communication between people only, and the Internet of Things (IOT) technology emerges as the times require. Machine to Machine (M2M) is an abbreviation for the mutual transmission of information and data between machines through a wireless network, and is an important direction for the development of IOT. Most M2M devices are relatively small, battery-powered systems, such as smart meter reading systems, which need to periodically monitor and report the usage of water, electricity, and gas.

智能抄表型业务一般主要是小数据包上报业务，数据量小，针对此类业务主要有两种传输方案，一种是基于控制面(Control Plane,CP)传输方案，一种是基于用户面(UserPlane，UP)传输方案。现有的用户设备(User Equipment，UE)的能力信息获取是基站在与移动性管理实体(Mobility Management Entity，MME)建立连接后，若MME保存有UE的能力信息，MME向基站发送的，或是，若MME未保存有UE的能力信息，基站向UE索要，并向MME发送的，而对于使用CP传输数据的方案，使用现有的UE的能力信息获取方法，会导致UE在发送数据时，基站没有该UE的能力信息。如此，可能会导致基站无法根据UE的能力信息为UE进行合理的分配数据调度资源，从而降低资源的利用率。Smart meter reading services are generally small data packet reporting services with a small amount of data. There are two transmission schemes for such services, one is based on the control plane (CP) transmission scheme, and the other is based on the user plane. (UserPlane, UP) transmission scheme. The capability information acquisition of the existing user equipment (User Equipment, UE) is sent by the MME to the base station if the MME saves the capability information of the UE after the base station establishes a connection with the mobility management entity (Mobility Management Entity, MME), or Yes, if the MME does not store the capability information of the UE, the base station asks the UE for it and sends it to the MME. For the scheme of using the CP to transmit data, using the existing method for obtaining the capability information of the UE will cause the UE to send data. , the base station does not have the capability information of the UE. In this way, the base station may not be able to reasonably allocate data scheduling resources for the UE according to the capability information of the UE, thereby reducing the utilization rate of the resources.

与上述描述的技术方案一致的，作为一个具体实施例，图3是包括基站的具体执行过程的数据调度方法的流程示意图。尽管这里描述的数据调度方法是基于图2所示的基站来执行，但需要注意的是，本发明实施例公开的数据调度方法的具体运行环境不仅限于上述基站。Consistent with the technical solutions described above, as a specific embodiment, FIG. 3 is a schematic flowchart of a data scheduling method including a specific execution process of a base station. Although the data scheduling method described here is performed based on the base station shown in FIG. 2 , it should be noted that the specific operating environment of the data scheduling method disclosed in the embodiments of the present invention is not limited to the above-mentioned base station.

如图3所示，本发明方法实施例公开的数据调度方法具体包括以下步骤：As shown in FIG. 3 , the data scheduling method disclosed by the method embodiment of the present invention specifically includes the following steps:

S301、基站获取用户设备UE的能力信息，其中，所述获取所述UE的能力信息的时刻处于所述基站接收到所述UE向所述基站发送的无线资源控制RRC连接建立完成信令之前。S301. A base station acquires capability information of a user equipment UE, wherein the time for acquiring the capability information of the UE is before the base station receives the radio resource control RRC connection establishment completion signaling sent by the UE to the base station.

可选的，UE的能力信息可以包括以下至少一种：UE优先级、(单频段/多频段部署)One band/multi-band deployment、单载波/多载波指示Single-tone/multi-tone指示(调度的单位的指示，具体可以指单个子载波，载波等等)、(控制面/用户面指示)CP/UPindication、(UE种类)UE-Category、签约属性标识符(Subscribe Profile Identifier，SPID)、(无线电能力)Radio capability、(接入层-版本信息)Access Stratum Release、多进程混合自动重传请求(Hybrid-ARQ，HARQ)能力、大容量传输块(Transport Block Size，TBS)能力、新功率类型(New Power Class)、移动性增强指示、重建立指示。Optionally, the capability information of the UE may include at least one of the following: UE priority, (single-band/multi-band deployment) One band/multi-band deployment, single-carrier/multi-carrier indication Single-tone/multi-tone indication ( The indication of the scheduling unit, which may specifically refer to a single subcarrier, carrier, etc.), (control plane/user plane indication) CP/UPindication, (UE type) UE-Category, subscription profile identifier (Subscribe Profile Identifier, SPID), (Radio capability) Radio capability, (Access Stratum-version information) Access Stratum Release, Multi-Process Hybrid Automatic Repeat Request (Hybrid-ARQ, HARQ) capability, Large-capacity Transport Block (Transport Block Size, TBS) capability, new power Type (New Power Class), Mobility Enhancement Indication, Re-establishment Indication.

示例性的，UE种类UE-Category包括支持或需要多进程HARQ的UE和/或支持或需要大TBS的UE。Exemplarily, the UE-category UE-Category includes UEs that support or require multi-process HARQ and/or UEs that support or require large TBS.

示例性的，重建立指示包括UP(用户面)的重建立指示和/或CP(控制面)的重建立指示。Exemplarily, the re-establishment indication includes a UP (user plane) re-establishment indication and/or a CP (control plane) re-establishment indication.

示例性的，UP的重建立指示用于区分重建立后是否支持移动性增强的指示。Exemplarily, the re-establishment indication of the UP is used to differentiate the indication of whether mobility enhancement is supported after the re-establishment.

示例性的，CP的重建立指示用于指示重建立连接是用于CP方案的重建立或用于区分CP的指示还是UP的指示。Exemplarily, the re-establishment indication of the CP is used to indicate whether the re-establishment of the connection is for the re-establishment of the CP scheme or the indication for distinguishing the CP or the UP indication.

示例性的，所述重建立指示在所述UE向所述基站发送的一个消息中携带，所述重建立指示作为一个建立原因值进行指示。Exemplarily, the re-establishment indication is carried in a message sent by the UE to the base station, and the re-establishment indication is indicated as an establishment cause value.

示例性的，上述重建立指示在在所述UE向所述基站发送的消息中携带，这个消息可以为RRC连接重建立请求、RRC连接建立请求或RRC恢复连接请求等等。Exemplarily, the above re-establishment indication is carried in a message sent by the UE to the base station, and the message may be an RRC connection re-establishment request, an RRC connection establishment request, or an RRC connection recovery request, and so on.

示例性的，重建立指示可在上述消息用作建立原因值进行指示，或者，重建立指示可在上述消息中作为一个指示信元。Exemplarily, the re-establishment indication may be used as the establishment cause value in the above-mentioned message to indicate, or the re-establishment indication may be used as an indication information element in the above-mentioned message.

其中，对于CP方案，在R13中并不支持重建立流程，但是在R14引入后，需要进行CP方案或UP方案的区分指示。重建立指示可以为仅用于CP方案的重建立指示，或者用于区分是CP重建还是UP方案重建的指示消息。重建立指示也可以区分不同版本UP重建的指示。其中，CP方案是指的是控制面的优化，UP方案是用户面的优化方案。Among them, for the CP scheme, the re-establishment process is not supported in R13, but after the introduction of R14, it is necessary to perform a distinction instruction of the CP scheme or the UP scheme. The re-establishment indication may be a re-establishment indication only for the CP scheme, or an indication message for distinguishing between CP re-establishment and UP scheme re-establishment. The re-establishment instructions can also differentiate the instructions for UP re-establishment of different versions. Among them, the CP scheme refers to the optimization of the control plane, and the UP scheme refers to the optimization of the user plane.

在R13版本的NB-IoT UP UE不支持移动性增强，即不支持在重建立流程中PDCPSTATUS REPORT流程以及X2口数据和UE上下文传递。在R14中，UE进行移动性增强，因此作为一种能力，可以考虑支持PDCP STATUS REPORT流程或上行数据重传，以及X2口数据和UE上下文传递，上行数据重传指的是：当UE在之前连接中有上行数据发送出去，但在换小区之前没有收到收方接受数据的确认时，在重建立过程中需要支持接收PDCP层的状态报告(PDCPSTATUS REPORT)，以便知道哪个上行PDCP SN号对应的数据没有发送到基站，从而进行重传。因为R13中不支持PDCP STATUS REPORT，因此UE无法做上行数据重传。The NB-IoT UP UE in the R13 version does not support mobility enhancement, that is, it does not support the PDCPSTATUS REPORT process and the X2 port data and UE context transfer in the re-establishment process. In R14, the UE performs mobility enhancement, so as a capability, it can be considered to support the PDCP STATUS REPORT procedure or uplink data retransmission, as well as X2 port data and UE context transfer. Uplink data retransmission refers to: when the UE is in the previous When there is uplink data sent out in the connection, but the receiver does not receive confirmation of data acceptance before changing cells, it is necessary to support receiving PDCP status report (PDCPSTATUS REPORT) during the re-establishment process, so as to know which uplink PDCP SN number corresponds to The data is not sent to the base station for retransmission. Because PDCP STATUS REPORT is not supported in R13, the UE cannot perform uplink data retransmission.

移动性增强指示作为UE的能力主要用于：当UE发生移动性时，如RLF触发的RRC连接重建立过程(如小区变更、小区切换或小区重选)时，当使用UP方案的UE向目标基站发送RRC连接重建立请求时，基站接收到该指示信息后，即可获知该UE可以支持基站间传递上下文、数据以及PDCP status report流程至少一种。这里的UE可以是NB-IoT中使用UP方案的UE。The mobility enhancement indication is mainly used as the capability of the UE: when the UE has mobility, such as the RRC connection re-establishment process (such as cell change, cell handover or cell reselection) triggered by RLF, when the UE using the UP scheme goes to the target When the base station sends the RRC connection re-establishment request, after the base station receives the indication information, it can know that the UE can support at least one of transferring context, data and PDCP status report process between base stations. The UE here may be a UE using the UP scheme in NB-IoT.

指示信息可以表示移动性增强能力指示，或者版本信息指示等其他信息。The indication information may indicate mobility enhancement capability indication, or other information such as version information indication.

若目标基站接收到相关指示信息后，可以在X2口传递指示信息，方便源基站做相应处理，并把UE上下文和数据转发到目标基站。指示信息包括移动性增强指示、UP的重建立指示、重建立指示或CP的重建立指示至少一种。If the target base station receives the relevant indication information, it can transmit the indication information on the X2 port, which is convenient for the source base station to do corresponding processing, and forward the UE context and data to the target base station. The indication information includes at least one of mobility enhancement indication, UP re-establishment indication, re-establishment indication or CP re-establishment indication.

可选的，所述基站广播所述基站是否支持移动性增强指示。Optionally, the base station broadcasts an indication of whether the base station supports mobility enhancement.

移动性增强从基站角度来看，可以看做是基站的一种能力，不同的基站对于UE的移动性支持的能力可能不一样，如R13版本的基站可能不支持用于CP的重建立流程或者不支持UP方案X2口data forwarding。但是R14的基站可能均支持，或者部分支持。基站可以进行是否支持移动性增强指示，可以对不同的能力进行单独指示如是否支持CP重建立或者UP的移动性增强，也可以作为移动性增强整体进行指示，如在系统消息中广播。具体的，当基站支持移动性增强能力时，基站通过系统广播进行指示，可以使用1bit整体指示或者多个bits对移动性增强包括的多个具体能力进行单独指示，当UE正在进行建立RRC连接或者RRC连接重建立时，可以根据指示消息选择是否接入。如当基站广播支持移动性增强能力时，支持移动性增强的UE可以选择接入，否则如果基站不支持，没有进行广播支持或者广播不支持，UE可以选择不接入该小区。当UE接入后，基站可以根据UE能力进行不同的操作，如低优先级处理，拒绝或者释放连接，将能力信息传递给其他节点等。From the point of view of the base station, mobility enhancement can be regarded as a capability of the base station. Different base stations may have different capabilities to support the mobility of the UE. For example, the base station of R13 version may not support the re-establishment process for CP or UP scheme X2 port data forwarding is not supported. However, R14 base stations may support all or some of them. The base station can indicate whether to support mobility enhancement, and can individually indicate different capabilities, such as whether to support CP re-establishment or UP mobility enhancement, or as a whole for mobility enhancement, such as broadcast in system messages. Specifically, when the base station supports the mobility enhancement capability, the base station indicates through system broadcast, and can use 1 bit overall indication or multiple bits to individually indicate multiple specific capabilities included in the mobility enhancement. When the UE is establishing an RRC connection or When the RRC connection is re-established, whether to access or not can be selected according to the indication message. For example, when the base station broadcasts the support for mobility enhancement, the UE that supports the mobility enhancement can choose to access; otherwise, if the base station does not support it, does not support the broadcast or does not support the broadcast, the UE can choose not to access the cell. After the UE accesses, the base station can perform different operations according to the UE capability, such as low priority processing, rejecting or releasing the connection, and transferring capability information to other nodes.

可选的，基站也可以通过专用信令来通知UE其是否支持移动性增强能力，当UE接入小区后，基站可以通过专用信令来通知，如RRC连接建立、RRC连接重建立、RRC连接拒绝或者释放消息或者其他消息。Optionally, the base station can also notify the UE whether it supports the mobility enhancement capability through dedicated signaling. When the UE accesses the cell, the base station can notify through dedicated signaling, such as RRC connection establishment, RRC connection re-establishment, RRC connection Reject or release messages or other messages.

具体的，如当UE接入目标小区时，当UE发送RRC连接重建立请求后，若目标基站没有可用的UE上下文，且不支持移动性增强能力时，则目标基站通过专用信令来通知UE。Specifically, for example, when the UE accesses the target cell, after the UE sends an RRC connection re-establishment request, if the target base station has no available UE context and does not support the mobility enhancement capability, the target base station notifies the UE through dedicated signaling. .

可选的，当UE在小区选择或者重选时，可以考虑这个因素进行选择小区。可选的方式有，基站广播一些支持移动性增强的小区，并且基站可以在系统广播中广播一个具有移动性增强能力偏置量(offset),对于支持移动性增强的能力的UE可以使用该offset进行小区选择或重选。可选的方式还有，只针对支持移动性增强能力的小区，进行重选或者选择，可以使用ranking机制，或者优先级机制。或者对支持移动性增强的UE，可以将支持移动性增强的小区认为是高优先级，在选择时可以优先选择。可选的，若基站获知其他小区是否支持移动性增强能力时，基站可以对支持移动性增强能力的小区设置cell specific的offset。Optionally, when the UE selects or reselects a cell, this factor may be considered to select a cell. Optionally, the base station broadcasts some cells that support mobility enhancement, and the base station can broadcast a mobility enhancement capability offset (offset) in the system broadcast, and the UE supporting mobility enhancement capability can use the offset. Perform cell selection or reselection. An optional way is to perform reselection or selection only for cells that support the mobility enhancement capability, and a ranking mechanism or a priority mechanism may be used. Or for the UE supporting mobility enhancement, the cell supporting mobility enhancement may be considered as a high priority, and may be selected preferentially during selection. Optionally, if the base station knows whether other cells support the mobility enhancement capability, the base station may set a cell specific offset for the cell supporting the mobility enhancement capability.

对于一个UE已经接入支持移动性增强的小区时，当其发生移动性时，如切换，或者RLF触发重建立流程，或者连接态小区重选时，如果UE接入的目标基站不支持移动性增强，可以理解为不支持UE上下文、数据的基站间转发等操作，则目标基站可以拒绝或释放UE的连接，或者重定向到其他支持该特性的小区或者重新建立连接。或者目标基站可以向源基站进行指示，源基站可以根据指示信息紧将UE上下文传递即可，或者通知源基站删除保存UE上下文和数据。When a UE has accessed a cell that supports mobility enhancement, when mobility occurs, such as handover, or RLF triggers the re-establishment process, or when the connected cell is reselected, if the target base station accessed by the UE does not support mobility Enhanced, it can be understood that operations such as UE context and data forwarding between base stations are not supported, and the target base station can reject or release the UE connection, or redirect to other cells that support this feature or re-establish the connection. Alternatively, the target base station may instruct the source base station, and the source base station may immediately transfer the UE context according to the instruction information, or notify the source base station to delete and save the UE context and data.

若UE开始接入的基站不支持移动性增强，而发生移动性后，接入小区的目标基站支持转发数据和UE上下文，可选的UE可以向目标基站进行指示之前所建立的连接的基站不支持移动性增强，目标基站若没有UE的上下文则可以拒绝或释放连接，或者重新建立连接，或者当目标基站接收到UE重建请求时，向源基站发生RLF indication或者重新获取上下文请求或者其他指示消息时，源基站可以回复包含拒绝或者不支持该操作的指示信息，或者只转移UE上下文，不转移数据，并进行指示。具体承载消息不限制，可以是现有X2口消息，也可是新的消息。If the base station to which the UE starts to access does not support mobility enhancement, and after mobility occurs, the target base station of the access cell supports forwarding data and UE context, the optional UE may indicate to the target base station that the base station of the previously established connection does not Support mobility enhancement, if the target base station does not have the context of the UE, it can reject or release the connection, or re-establish the connection, or when the target base station receives the UE re-establishment request, it will send an RLF indication to the source base station or re-acquire the context request or other indication messages At this time, the source base station can reply with indication information that rejects or does not support the operation, or only transfers the UE context without transferring the data, and gives an indication. The specific bearer message is not limited, and may be an existing X2 port message or a new message.

所述基站广播所述基站的多播业务针对的UE种类或使用的UE能力的指示。针对多播业务，比如，NB-IoT中的单小区点对多点(Single Cell Point To Multiploint，SC-PTM)业务，由于不同UE的种类和能力不同，基站需要广播此类多播业务传输所针对的UE种类或能力的指示，以便UE根据其种类或能力，决定是否接受多播业务。比如，上述指示可能包含：多播业务传输时使用普通TBS还是大TBS的指示，使用单HARQ进程还是多HARQ进程的指示以及针对的UE种类指示等。此外，由于网络中同时进行的SC-PTM业务有多个，上述指示可以针对当前小区中所有的SC-PTM业务。为了灵活控制，基站也可以为每个SC-PTM业务分别进行上述指示。The base station broadcasts the indication of the UE type or the used UE capability for the multicast service of the base station. For multicast services, such as the Single Cell Point To Multiploint (SC-PTM) service in NB-IoT, due to the different types and capabilities of different UEs, the base station needs to broadcast the transmission information of such multicast services. The indication of the type or capability of the targeted UE, so that the UE can decide whether to accept the multicast service according to its type or capability. For example, the above indication may include: an indication of whether to use a normal TBS or a large TBS during multicast service transmission, an indication of whether to use a single HARQ process or multiple HARQ processes, and an indication of the type of UE targeted. In addition, since there are multiple SC-PTM services running simultaneously in the network, the above indication can be directed to all SC-PTM services in the current cell. For flexible control, the base station may also perform the above indication for each SC-PTM service separately.

需要说明的是，基站广播基站的多播业务针对的UE种类或使用的UE能力的指示的时间位置可以是在以上步骤S301之前，也可以不是在以上步骤S301之前，同时，空闲态UE也可以接收上述指示，本发明不作限定。It should be noted that the time position of the indication of the UE type or the UE capability used by the base station broadcasting the multicast service of the base station may be before the above step S301 or not before the above step S301, at the same time, the idle state UE may also be After receiving the above instructions, the present invention is not limited.

可选的，所述新功率类型包含在承载所述RRC连接建立请求的MAC协议数据单元(MAC PDU)的控制元素(MAC CE)中。比如，如图3a所示的数据量和功率余量上报(DataVolume and Power Headroom Report)的MAC CE中，指示UE的新功率类型。具体方式可以为，利用现有的预留比特R进行新功率类型指示，使用的预留比特个数取决于需要指示的新功率类型个数，若网络中只支持一个新功率类型，则可以只使用一个预留比特作为新功率类型指示；若网络中支持两个或三个新功率类型，则需要使用两个预留比特作为新功率类型指示。使用现有MAC CE中的预留比特进行新功率类型指示，可以避免设计新的MAC CE，同时，新功率类型和其他信息一起上报给基站，也可以减少信令开销。Optionally, the new power type is included in a control element (MAC CE) of a MAC protocol data unit (MAC PDU) carrying the RRC connection establishment request. For example, in the MAC CE of the data volume and power headroom report (Data Volume and Power Headroom Report) as shown in FIG. 3a, the new power type of the UE is indicated. The specific method may be as follows: using the existing reserved bits R to indicate the new power type, the number of reserved bits used depends on the number of new power types to be indicated. If only one new power type is supported in the network, only one new power type can be used One reserved bit is used as the new power type indication; if two or three new power types are supported in the network, two reserved bits need to be used as the new power type indication. Using the reserved bits in the existing MAC CE to indicate the new power type can avoid designing a new MAC CE, and at the same time, the new power type and other information are reported to the base station, which can also reduce signaling overhead.

Specifically, the RRC connection request sent by the UE to the base station carries the capability information of the UE, where the capability information may be all the capability information of the UE, or part of the capability information of the UE, depending on the capacity of the RRC connection request signaling. . If the capacity of the above-mentioned RRC connection request signaling is sufficient, the above-mentioned RRC connection request signaling carries all the capability information of the UE. If the capacity of the above-mentioned RRC connection request signaling is limited, the above-mentioned RRC connection request signaling carries some necessary capability information of the UE, such as UE priority, Single-tone/multi-tone indication, CP/UP indication, etc. Optionally, the capability information of some UEs may be divided into groups, written into the protocol, and only the index number of a certain UE capability information group may be carried in the above-mentioned RRC connection request signaling, without carrying the capability information of the UE.

可选的，基站获取用户设备UE的能力信息的具体实现方式为：基站接收核心网发送的携带上述UE的能力信息的寻呼消息。具体地，核心网向基站下发寻呼消息时，若核心网存储有上述UE上下文信息，核心网在向基站发送的寻呼消息中携带上述UE的能力信息，上述UE上下文信息包含上述UE的能力信息，基站接收到上述UE的能力信息之后，将上述UE的能力信息进行保存，以便于后续与上述UE连接后使用。Optionally, a specific implementation manner for the base station to acquire the capability information of the user equipment UE is: the base station receives a paging message that carries the capability information of the UE and is sent by the core network. Specifically, when the core network sends a paging message to the base station, if the core network stores the UE context information, the core network sends the paging message to the base station to carry the capability information of the UE, and the UE context information includes the UE context information. Capability information, after receiving the capability information of the UE, the base station saves the capability information of the UE, so as to be used after connecting with the UE in the future.

Specifically, if the core network does not store the UE context information, the first paging message sent by the core network to the base station does not carry the capability information of the UE. At this time, the base station is sending the second paging message to the UE. Indication information is added in , the indication information is used to indicate that the subsequent UE needs to report the capability information of the UE to the base station, and the UE may carry the capability information of the UE in the subsequent RRC connection request signaling sent to the base station.

具体地，由于UE向基站下发的RRC连接请求信令的容量有限，此时上述RRC连接请求信令可能只携带UE的部分必要能力信息(第一能力信息)，如UE优先级，Single-tone/multi-tone指示，CP/UP指示等。若后续UE仍有数据需要上传，为了基站能够更合理的为UE分配数据调度资源，在UE向基站发送第一能力信息之后，基站需要获取UE剩余的能力信息，其获取方法具体可以包括以下几种：1、核心网可在向基站下发的初始上下文建立请求信令(或是核心网向基站下发的其他信令)中携带第二能力信息，可选的，可在核心网向基站发送的初始上下文建立请求信令(或是核心网向基站发送的其他信令)之前，基站在向核心网发送的初始UE信息信令中携带指示信息，指示核心网向基站发送UE的哪些能力信息；2、基站向UE发送上述UE的能力信息获取请求(具体基站可通过向UE发送的UE能力信息获取信令，或是基站向UE下发的其他信令来实现)，上述UE的能力信息获取请求可携带指示信息，指示UE向基站发送UE的哪些能力信息，UE响应上述UE的能力信息获取请求而向基站发送第三能力信息；3、核心网有下行数据下发时，核心网可在向基站发送的下行NAS传输信令中携带第四能力信息；4、UE向基站发送的RRC连接建立完成信令，该信令携带UE的第五能力信息，可选的，在UE向基站发送的RRC连接建立完成信令之前，基站可在向UE发送的RRC连接建立请求信令中携带指示信息，指示核心网向基站发送UE的哪些能力信息，可选的，由于RRC连接建立完成信令容量较大，在该条信令中可携带UE的全部能力信息，该种情况下，第五能力信息可包含第一能力信息。Specifically, since the capacity of the RRC connection request signaling sent by the UE to the base station is limited, the above-mentioned RRC connection request signaling may only carry part of the necessary capability information (first capability information) of the UE, such as UE priority, Single- tone/multi-tone indication, CP/UP indication, etc. If the UE still has data to upload in the future, in order for the base station to allocate data scheduling resources to the UE more reasonably, after the UE sends the first capability information to the base station, the base station needs to obtain the remaining capability information of the UE. The obtaining method may include the following: Types: 1.

举例来说，请参见图3.3，图3.3为发明实施例公开的另一种数据调度方法的流程示意图。For example, please refer to FIG. 3.3, which is a schematic flowchart of another data scheduling method disclosed in an embodiment of the invention.

可选的，基站获取用户设备UE的能力信息的具体实现方式为：基站接收UE发送的RRC连接请求，上述RRC连接请求携带第一核心网的路由辅助信息，上述第一核心网为存储有上述UE上下文信息的核心网；上述基站根据上述第一核心网的路由辅助信息确定核心网和核心网识别UE的标识信息；上述基站向确定后的核心网发送上述UE的能力信息获取请求，上述UE的能力信息获取请求携带上述核心网识别UE的标识信息，上述核心网识别UE的标识信息用于上述确定后的核心网获取上述UE上下文信息，上述UE上下文信息包含上述UE的能力信息；基站接收上述确定后的核心网响应上述UE的能力信息获取请求而发送的上述UE的能力信息。Optionally, a specific implementation manner for the base station to acquire the capability information of the user equipment UE is: the base station receives an RRC connection request sent by the UE, and the RRC connection request carries the routing assistance information of the first core network, and the first core network stores the above-mentioned RRC connection request. The core network of UE context information; the base station determines the identification information of the core network and the core network to identify the UE according to the routing assistance information of the first core network; the base station sends the capability information acquisition request of the UE to the determined core network, and the UE The capability information acquisition request carries the identification information of the UE identified by the core network, and the identification information of the UE identified by the core network is used for the determined core network to obtain the context information of the UE, and the context information of the UE includes the capability information of the UE; the base station receives The above-mentioned capability information of the UE sent by the determined core network in response to the request for obtaining the capability information of the above-mentioned UE.

举例来说，基站在向核心网发送UE的能力信息获取请求时，携带核心网识别UE的标识信息(其中，核心网识别UE的标识信息用于核心网根据该标识信息寻找存储于核心网内的上述UE的上下文信息，核心网识别UE的标识信息可以是全球唯一临时UE标识(Globally Unique Temporary UE Identity，GUTI)，也可以是全球唯一的移动性管理实体MME标识(Globally Unique MME Identity，GUMMEI)和系统架构演进(systemarchitecture evolution，SAE)临时移动用户标识S-TMSI的组合，或者S-TMSI，或者eNBMME UE S1AP ID，或者S1AP UE id pair(S1-AP UE ID对)等等)，用于确定后的核心网验证是否是保存有上述UE上下文信息的核心网(或者UE之前注册的核心网)，如果是，确定后的核心网可直接根据核心网识别UE的标识信息获取预先存储的上述UE的上下文信息，如果不是，那么确定后的核心网根据该核心网识别UE的标识信息向UE之前连接的核心网(第一核心网)获取UE的上下文信息，然后确定后的核心网再通过向基站发送的信令中将UE的能力信息携带给基站。For example, when the base station sends the UE's capability information acquisition request to the core network, it carries the identification information of the core network to identify the UE (wherein, the core network identifies the identification information of the UE is used by the core network to search for storage in the core network according to the identification information. The context information of the above-mentioned UE, the identity information that the core network identifies the UE may be a globally unique temporary UE identity (Globally Unique Temporary UE Identity, GUTI), or a globally unique mobility management entity MME identity (Globally Unique MME Identity, GUMMEI) ) and the combination of system architecture evolution (system architecture evolution, SAE) temporary mobile subscriber identity S-TMSI, or S-TMSI, or eNBMME UE S1AP ID, or S1AP UE id pair (S1-AP UE ID pair), etc.), use The determined core network verifies whether it is the core network that holds the above-mentioned UE context information (or the core network previously registered by the UE). If the above-mentioned context information of the UE is not, then the determined core network obtains the context information of the UE from the core network (first core network) connected before the UE according to the identification information of the UE identified by the core network, and then the determined core network re-runs. The capability information of the UE is carried to the base station through the signaling sent to the base station.

可选的，GUTI由PLMN ID、MMEI以及M-TMSI组成，其具体的组成如图3.3b所示。Optionally, GUTI is composed of PLMN ID, MMEI and M-TMSI, and its specific composition is shown in Figure 3.3b.

可选的，基站向确定后的核心网发送上述UE的能力信息获取请求可以是基站向核心网发送的UE能力信息请求信令实现的，也可以是基站向核心网发送的其他信令实现的，本发明不作限定。Optionally, the fact that the base station sends the above-mentioned UE capability information acquisition request to the determined core network may be implemented by the UE capability information request signaling sent by the base station to the core network, or it may be implemented by other signaling sent by the base station to the core network. , the present invention is not limited.

可选的，图3.4所示，在以上步骤S301所述基站获取用户设备UE的能力信息之后，还包括：所述基站向所述UE发送UE能力使用的指示信息，所述UE能力使用的指示信息用于指示数据调度使用的UE能力，所述UE能力使用的指示信息包括指示数据调度是否使用多进程HARQ的指示信息和/或指示数据调度是否使用TBS的指示信息。Optionally, as shown in Figure 3.4, after the base station acquires the capability information of the user equipment UE in the above step S301, it further includes: the base station sends the UE capability usage indication information, the UE capability usage indication The information is used to indicate UE capability used for data scheduling, and the indication information for UE capability usage includes indication information indicating whether data scheduling uses multi-process HARQ and/or indication information indicating whether data scheduling uses TBS.

举例来说，目前，3GPP组织已完成NB-IoT的Rel-13版本的标准化，正在Rel-14版本中对NB-IoT进行增强。其中，由于Rel-13中NB-IoT终端支持的速率较低，应用场景受限，Rel-14版本NB-IoT引入两个新的特性，双HARQ进程(Rel-13只有单进程)以及更大的TBS，对NB-IoT终端进行传输速率增强。目前，基站获取UE能力中不包括新引入的2HARQ进程能力或大TBS能力，基站无法在RRC连接建立消息中或后续的数据调度中使用这两种新特性对UE进行调度。进而影响调度的性能。For example, at present, the 3GPP organization has completed the standardization of the Rel-13 version of NB-IoT, and is enhancing NB-IoT in the Rel-14 version. Among them, due to the low rate supported by NB-IoT terminals in Rel-13 and limited application scenarios, Rel-14 version NB-IoT introduces two new features, dual HARQ processes (Rel-13 only has a single process) and larger The TBS of NB-IoT enhances the transmission rate of the NB-IoT terminal. Currently, the newly introduced 2HARQ process capability or large TBS capability is not included in the UE capability acquired by the base station, and the base station cannot use these two new features to schedule the UE in the RRC connection establishment message or subsequent data scheduling. This in turn affects the scheduling performance.

本发明实施例基站先获取UE能力，然后指示UE是否支持多进程HARQ能力和大TBS能力的新特性，若获取的UE能力支持这两种新特性时，基站可以在RRC连接建立消息中，指示UE是否在后续数据调度中使用这两种新特性。其中，UE对于这两种特性的支持，分别指示，比如用一个单独指示(如1bit)指示是否支持多进程HARQ，另一个单独指示来指示是否支持大TBS；当然也可以用一个统一的指示，指示UE是否同时支持这两种特性(因为这两种特性都是为了实现高数据率，统一指示开销更小)。另外，指示的名称可以为UE能力，也可以为UE类型。另外，基站对于UE的指示，同样可以是两个单独的指示，也可以是一个统一的指示。In this embodiment of the present invention, the base station first obtains the UE capability, and then indicates whether the UE supports the new features of multi-process HARQ capability and large TBS capability. If the obtained UE capability supports these two new features, the base station may indicate in the RRC connection establishment message. Whether the UE uses these two new features in subsequent data scheduling. Among them, the UE's support for these two characteristics is indicated separately, for example, a separate indication (such as 1 bit) is used to indicate whether multi-process HARQ is supported, and another separate indication is used to indicate whether large TBS is supported; of course, a unified indication can also be used, Indicates whether the UE supports both features at the same time (because both features are to achieve high data rates, the unified indication overhead is smaller). In addition, the indicated name may be UE capability or UE type. In addition, the indication of the base station to the UE may also be two separate indications, or may be a unified indication.

另外，基站之所以需要向UE指示是：这两种新特性均为了提供更高的传输速率，而NB-IoT首先要保证网络的覆盖。当UE的覆盖较差时，由于需要大量重复发送增强覆盖，高传输速率本身无法实现。也就是说，尽管部分新的或能力较强的UE具备支持这两种新特性的能力，但是，在一些情况下(比如UE覆盖较差)，基站并不一定会使用这两种新特性对UE进行调度。由于是否使用这两种特性关系到UE的下行控制信息(Downlink ControlInformation，DCI)格式、非连续接收行为时序关系等，因此，为了避免调度失败或传输效率降低的问题，基站需要指示UE是否使用这两种能力进行后续调度。In addition, the reason why the base station needs to indicate to the UE is that these two new features are both to provide higher transmission rates, and NB-IoT must first ensure network coverage. When the coverage of the UE is poor, a high transmission rate cannot be achieved by itself due to the need for a large number of repeated transmissions to enhance the coverage. That is to say, although some new or relatively capable UEs have the ability to support these two new features, in some cases (such as poor UE coverage), the base station may not necessarily use these two new features to pair The UE performs scheduling. Whether or not to use these two features is related to the format of the downlink control information (DCI) of the UE, the timing relationship of the discontinuous reception behavior, etc. Therefore, in order to avoid the problem of scheduling failure or reduction of transmission efficiency, the base station needs to indicate whether the UE uses this feature. Two capabilities for subsequent scheduling.

可选的，基站根据第一核心网的路由辅助信息确定核心网和核心网识别UE的标识信息的具体实现方式为：基站根据第一核心网的路由辅助信息，确定第一核心网的GUMMEI和核心网识别UE的标识信息；基站根据上述GUMMEI，确定基站可选的核心网是否包含有第一核心网；若基站可选的核心网包含有第一核心网，基站选择第一核心网；若基站可选的核心网不包含有第一核心网，基站选择基站可选的核心网中的任意一个核心网。Optionally, a specific implementation manner for the base station to determine the identification information of the core network and the core network to identify the UE according to the routing assistance information of the first core network is as follows: the base station determines the GUMMEI and GUMMEI of the first core network according to the routing assistance information of the first core network. The core network identifies the identification information of the UE; the base station determines whether the optional core network of the base station includes the first core network according to the above GUMMEI; if the optional core network of the base station includes the first core network, the base station selects the first core network; The core network selectable by the base station does not include the first core network, and the base station selects any one of the core networks selectable by the base station.

举例来说，UE向基站发送的RRC连接请求信令中携带第一核心网的路由辅助信息，基站可根据第一核心网的路由辅助信息确定第一核心网的GUMMEI和核心网识别UE的标识信息。基站根据GUMMEI确定基站是否可连接第一核心网。若基站可连接的核心网存在第一核心网，基站选择第一核心网，若基站可连接的核心网不存在第一核心网，基站选择基站可连接的核心网中的任意一个核心网。For example, the RRC connection request signaling sent by the UE to the base station carries the routing assistance information of the first core network, and the base station can determine the GUMMEI of the first core network and the identity of the core network to identify the UE according to the routing assistance information of the first core network. information. The base station determines whether the base station can connect to the first core network according to the GUMMEI. If the first core network exists in the core network that the base station can connect to, the base station selects the first core network.

可选的，第一核心网路由辅助信息包括S-TMSI。Optionally, the routing assistance information of the first core network includes S-TMSI.

可选的，第一核心网路由辅助信息包括以下至少一种：选择的公共陆地移动网络地址索引/公共陆地移动网络地址(Public Land Mobile Network，PLMN)ID、移动性管理实体MME组标识(MME group ID，MMEGI)。Optionally, the first core network routing assistance information includes at least one of the following: selected public land mobile network address index/public land mobile network address (Public Land Mobile Network, PLMN) ID, mobility management entity MME group identifier (MME group ID, MMEGI).

可选的，第一核心网的路由辅助信息包括S-TMSI以及选择的公共陆地移动网络地址索引/PLMN ID，基站根据第一核心网的路由辅助信息，确定第一核心网的全球唯一的移动性管理实体MME标识GUMMEI和核心网识别UE的标识信息的具体实现方式为：基站根据S-TMSI以及选择的公共陆地移动网络地址索引/PLMN ID，从基站中获取第一核心网的MMEGI；根据S-TMSI、选择的公共陆地移动网络地址索引/PLMN ID以及MMEGI，确定第一核心网的全球唯一的移动性管理实体MME标识GUMMEI和核心网识别UE的标识信息。Optionally, the routing assistance information of the first core network includes the S-TMSI and the selected public land mobile network address index/PLMN ID, and the base station determines the globally unique mobile network of the first core network according to the routing assistance information of the first core network. The specific implementation of the identity management entity MME identification GUMMEI and the core network identification UE identification information is: the base station obtains the MMEGI of the first core network from the base station according to the S-TMSI and the selected public land mobile network address index/PLMN ID; The S-TMSI, the selected public land mobile network address index/PLMN ID and MMEGI determine the globally unique mobility management entity MME identity GUMMEI of the first core network and the identity information of the core network identifying the UE.

具体地，对于一些固定的UE，之前所连接的核心网组是不变的，也就是说这些UE所连接的核心网的MMEGI不变，基站可以将这些UE的MMEGI、S-TMSI等信息进行保存，这种情况下，UE在向基站发送的RRC连接请求中只需携带选择的公共陆地移动网络地址索引或者PLMN ID和S-TMSI即可，无需携带UE的MMEGI等信息，基站可根据选择的公共陆地移动网络地址索引/PLMN-ID和S-TMSI获取预先存储的MMEGI等信息，并根据PLMN-ID、S-TMSI以及MMEGI组成GUMMEI和核心网识别UE的标识信息。使用基站保存部分核心网的路由辅助信息信息，基站可以通过S-TMSI来作为识别码进行获取，当S-TMSI更新后，核心网可以通过发送给基站的某个下行信令进行携带，也可以是某些新的信令。比如RRC连接悬挂应答，S1-AP:S1 UE Deactivate Context Ack，初始上下文建立请求等，本发明不作限定。当然本发明实施例中的S-TMSI也可以是其他UE标识符，如C-RNTI等。需要说明的是，使用基站保存信息，不限于上述方法，其他利用基站保存信息，且使用S-TMSI或者其他UE与核心网交互更新的信息作为识别码的方法，均可使用上述方法。Specifically, for some fixed UEs, the core network group connected before is unchanged, that is to say, the MMEGI of the core network to which these UEs are connected is unchanged, and the base station can perform the MMEGI, S-TMSI and other information of these UEs. Save, in this case, the UE only needs to carry the selected public land mobile network address index or PLMN ID and S-TMSI in the RRC connection request sent to the base station, and does not need to carry information such as the MMEGI of the UE. The public land mobile network address index/PLMN-ID and S-TMSI obtained from the PLMN-ID and S-TMSI obtain pre-stored MMEGI and other information, and form GUMMEI and the core network to identify the UE's identification information according to the PLMN-ID, S-TMSI and MMEGI. The base station is used to store some of the routing assistance information of the core network. The base station can obtain it through the S-TMSI as an identification code. When the S-TMSI is updated, the core network can carry it through a certain downlink signaling sent to the base station, or is some new signaling. For example, RRC connection suspension response, S1-AP: S1 UE Deactivate Context Ack, initial context establishment request, etc., are not limited in the present invention. Of course, the S-TMSI in the embodiment of the present invention may also be other UE identifiers, such as C-RNTI and the like. It should be noted that the use of the base station to store information is not limited to the above method, and other methods of using the base station to store information and using S-TMSI or other information updated by the UE and the core network as the identification code can all use the above method.

When the UE enters the connected state from the idle state, the UE sends the base station The RRC connection request signaling carries the selected public land mobile network address index/PLMN-ID and S-TMSI. When the base station connected to the UE is the same as the base station connected to before, since the MMEGI of the core network to which the base station is connected is unique, the base station can determine the MMEGI of the core network to which the UE was previously connected according to the selected public land mobile network address index and S-TMSI. , the base station can identify the UE's identity information according to the PLMN-ID, S-TMSI and MMEGI which constitute the GUMMEI of the core network connected to the UE before and the core network. Subsequent base stations can obtain the capability information of the UE and the context information of the UE through the core network. For a specific implementation manner, please refer to the implementation manner described in Figure 3.3, which will not be described here.

The base station may determine, through the information carried by the UE, whether it is necessary to obtain the UE capability information through the method for obtaining the UE capability information described in Figure 3.3.

可选的，基站向确定后核心网发送上述UE的能力信息获取请求中可携带S-TMSI，以用于该核心网识别上述UE。可选的，基站向确定后的核心网发送上述UE的能力信息获取请求中可携带S-TMSI、eNB UE S1AP ID、LTE的跟踪区标识(Tracking Area Identity，TAI)、演进的UMTS陆地无线接入网(Evolved UMTS Terrestrial Radio Access Network，E-UTRAN CGI)、RRC建立原因；等等，该核心网向基站发送上述UE的能力信息时可携带上述UE能力信息、UE在MME侧S1接口上的唯一标识(MME UE S1Application Protocol ID，MMEUE S1AP ID)、UE在eNB侧S1接口上的唯一标识(eNB UE S1 Application Protocol ID，eNBUE S1AP ID)、UE聚合最大比特速率；等等。这样使得在后续基站向核心网发送的初始UE信息信令中仅携带NAS PDU，其中，上述初始UE信息信令可改为上行NAS传输信令，此处信令名称不限制。当然，当UE向基站发送RRC连接请求后，基站向核心网发送上述UE的能力请求的信令也可以改为初始UE信息信令/上行NAS传输信息，此处信令名称不作限定，携带内容同上。Optionally, the request for obtaining the capability information of the UE sent by the base station to the determined core network may carry the S-TMSI, so that the core network can identify the UE. Optionally, the base station sends the capability information acquisition request of the UE to the determined core network, which may carry the S-TMSI, the eNB UE S1AP ID, the LTE Tracking Area Identity (TAI), and the evolved UMTS terrestrial wireless access point. Network access (Evolved UMTS Terrestrial Radio Access Network, E-UTRAN CGI), RRC establishment reason; etc., when the core network sends the UE capability information to the base station, it may carry the UE capability information, the UE capability information on the S1 interface on the MME side.

In this way, only the NAS PDU is carried in the initial UE information signaling sent by the subsequent base station to the core network, wherein the above initial UE information signaling can be changed to uplink NAS transmission signaling, and the signaling name is not limited here. Of course, after the UE sends the RRC connection request to the base station, the signaling of the above-mentioned UE capability request sent by the base station to the core network can also be changed to the initial UE information signaling/uplink NAS transmission information. The signaling name here is not limited and carries the content Ditto.

举例来说，请参见图3.4，图3.4为发明实施例公开的另一种数据调度方法的流程示意图。For example, please refer to FIG. 3.4, which is a schematic flowchart of another data scheduling method disclosed in an embodiment of the invention.

可选的，基站获取用户设备UE的能力信息的具体实现方式为：基站接收UE发送的携带有第一基站的路由辅助信息的连接建立请求或连接重建立请求，所述第一基站为存储有第二核心网的路由辅助信息的基站，所述第二核心网为存储有所述UE上下文信息的核心网；基站根据所述第一基站的路由辅助信息，向所述第一基站索要第二核心网的路由辅助信息；基站根据所述第二核心网的路由辅助信息确定核心网和核心网识别UE的标识信息；基站向确定后的核心网发送所述UE上下文信息获取请求，所述UE的能力信息获取携带所述核心网识别UE的标识信息，所述核心网识别UE的标识信息用于所述确定后的核心网获取所述UE上下文信息，所述UE上下文信息包含所述UE的能力信息；基站接收所述确定后的核心网响应所述UE上下文信息获取请求而发送的所述UE上下文信息。Optionally, a specific implementation manner for the base station to obtain the capability information of the user equipment UE is: the base station receives a connection establishment request or a connection re-establishment request that is sent by the UE and carries the routing assistance information of the first base station, where the first base station stores a The base station of the routing assistance information of the second core network, where the second core network is the core network storing the UE context information; the base station asks the first base station for the second base station according to the routing assistance information of the first base station routing assistance information of the core network; the base station determines the identification information of the core network and the core network to identify the UE according to the routing assistance information of the second core network; the base station sends the UE context information acquisition request to the determined core network, and the UE The capability information acquisition carries the identification information of the core network to identify the UE, and the identification information of the core network to identify the UE is used for the determined core network to obtain the UE context information, and the UE context information includes the UE's capability information; the base station receives the UE context information sent by the determined core network in response to the UE context information acquisition request.

其中，上述第一基站的路由辅助信息包括小区接入网络临时标识(Cell RadioNetwork Temporary Identifier，C-RNTI)，物理小区标识，S-TMSI。The routing assistance information of the first base station includes a cell access network temporary identifier (Cell RadioNetwork Temporary Identifier, C-RNTI), a physical cell identifier, and an S-TMSI.

举例来说，当UE与所连接的基站发生连接失败时，UE与新的基站进行连接重建立操作，UE携带C-RNTI，物理小区标识，S-TMSI向新的基站发起连接重建立过程，以便于新的基站根据上述信息找到之前与UE连接的基站，并通过X2接口从之前与UE连接的基站获取之前与UE连接的核心网(第二核心网)的MMEGI等核心网路由辅助信息，进而得到UE之前所连接的核心网信息，并通过UE之前连接的核心网获取UE的上下文信息，完成连接重建立流程UE的上下文信息包含有UE的能力信息。基站获取UE的上下文信息的具体过程请参见图3.3所述的方法，在此不再叙述。如果UE当前连接的基站与之前的基站相通，则获取UE上下文信息流程相同。For example, when the connection between the UE and the connected base station fails, the UE performs a connection re-establishment operation with the new base station. The UE carries the C-RNTI, the physical cell identifier, and the S-TMSI to initiate the connection re-establishment process to the new base station. In order to facilitate the new base station to find the base station previously connected to the UE according to the above information, and obtain core network routing assistance information such as MMEGI of the core network (second core network) previously connected to the UE from the base station previously connected to the UE through the X2 interface, Further, the information of the core network connected to the UE before is obtained, and the context information of the UE is obtained through the core network connected to the UE before, and the connection re-establishment procedure is completed. The context information of the UE includes the capability information of the UE. For the specific process of the base station acquiring the context information of the UE, please refer to the method described in Figure 3.3, which will not be described here. If the base station to which the UE is currently connected is in communication with the previous base station, the process of acquiring the UE context information is the same.

S302、所述基站根据所述UE的能力信息为所述UE分配数据调度资源。S302. The base station allocates data scheduling resources to the UE according to the capability information of the UE.

具体的，基站接收上述UE的能力信息后，根据上述UE的能力信息为上述UE分配数据调度资源。并向UE发送RRC连接建立信令，上述RRC连接建立信令携带基站为上述UE分配的数据调度资源，UE接收到RRC连接建立信令后，发送RRC连接建立完成信令，并根据基站对UE分配的数据调度资源，在此时发送的NAS消息中携带UE需要上报网络的数据。Specifically, after receiving the capability information of the UE, the base station allocates data scheduling resources to the UE according to the capability information of the UE. Send the RRC connection establishment signaling to the UE. The RRC connection establishment signaling carries the data scheduling resources allocated by the base station for the UE. After receiving the RRC connection establishment signaling, the UE sends the RRC connection establishment complete signaling, and according to the base station, the UE For the allocated data scheduling resource, the NAS message sent at this time carries the data that the UE needs to report to the network.

举例来说，上述UE的能力信息包括CP/UP指示，基站会在后续的数据或者信令传输中，将PDCP的报头相应设置，例如使用CP传输数据时，PDCP报头短，而使用UP传输方案时PDCP报头长。CP/UP指示包括以下几种：1、利用UE发送给基站的RRC连接建立完成信令的分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)头进行指示，短字节(比如1字节)没有MAC-I表示CP，长字节(比如5字节)有MAC-I表示UP；2、如果UE连接的基站和之前连接基站的相同，都使用短的PDCP头进行发送RRC连接请求，如果基站侧有该UE的上下文，则表示UP，则基站根据UP特性进行后续的相关配置，如果基站侧没有UE的上下文，则基站根据CP特性进行后续的相关配置。3、如果UE连接的基站和之前的基站不相同，同样使用短的PDCP头进行发送RRC连接建立完成信令，基站侧无该UE上下文信息，则基站仍使用CP的相关配置，在UE发送完RRC连接建立完成信令后，基站可根据NAS包大小判断出是CP还是UP，并进行后续配置。4、同样的第二种和第三种CP/UP指示也可使用长的PDCP头，其后续的UP/CP配置于第二种和第三种CP/UP指示相同，在此不再叙述；5、若无法根据数据包大小识别CP还是UP，则当核心网收到包后，通过下行信令来通知基站，用于后续数据传输。或者可以说UE和核心网进行信息交互后，知道具体选择的是CP还是UP后，再通过核心网下发基站的下行信令告诉基站是CP还是UP。For example, the capability information of the UE includes the CP/UP indication, and the base station will set the PDCP header accordingly in subsequent data or signaling transmission. For example, when using CP to transmit data, the PDCP header is short, and the UP transmission scheme is used. When the PDCP header is long. The CP/UP indication includes the following: 1. Use the Packet Data Convergence Protocol (PDCP) header of the RRC connection establishment completion signaling sent by the UE to the base station to indicate, and the short byte (such as 1 byte) does not MAC-I indicates CP, and long bytes (such as 5 bytes) have MAC-I to indicate UP; 2. If the base station connected to the UE is the same as the base station connected to before, the short PDCP header is used to send the RRC connection request. If there is the context of the UE on the side, it means UP, and the base station performs subsequent related configurations according to the UP characteristics. If the base station side does not have the context of the UE, the base station performs subsequent related configurations according to the CP characteristics. 3. If the base station connected to the UE is not the same as the previous base station, a short PDCP header is also used to send the RRC connection establishment completion signaling, and the base station side does not have the UE context information, the base station still uses the relevant configuration of the CP. After the signaling of the RRC connection establishment is completed, the base station can determine whether it is CP or UP according to the size of the NAS packet, and perform subsequent configuration. 4. The same second and third CP/UP instructions can also use a long PDCP header, and the subsequent UP/CP configuration is the same as the second and third CP/UP instructions, and will not be described here; 5. If the CP or UP cannot be identified according to the size of the data packet, when the core network receives the packet, it will notify the base station through downlink signaling for subsequent data transmission. Or it can be said that after the UE exchanges information with the core network and knows whether to select the CP or the UP, the core network sends the downlink signaling of the base station to tell the base station whether it is the CP or the UP.

可以看出，在本发明实施例中，基站获取UE的能力信息，其中，基站获取UE的能力信息的时刻处于基站接收到UE向基站发送的无线资源控制协议RRC连接建立完成信令之前，由于在基于CP传输方案进行数据传输时，数据是在UE向基站发送的RRC连接建立完成信令中携带的NAS消息携带的，因此，基站在UE数据发送之前获得UE的能力信息，可使得基站根据UE的能力信息为UE进行合理的分配数据调度资源，从而提高资源的利用率。It can be seen that, in this embodiment of the present invention, the base station obtains the capability information of the UE, and the time when the base station obtains the capability information of the UE is before the base station receives the radio resource control protocol RRC connection establishment completion signaling sent by the UE to the base station. When data transmission is performed based on the CP transmission scheme, the data is carried in the NAS message carried in the RRC connection establishment completion signaling sent by the UE to the base station. Therefore, the base station obtains the UE's capability information before the UE data is sent, which enables the base station to The capability information of the UE reasonably allocates data scheduling resources for the UE, thereby improving the utilization rate of the resources.

与上述描述的技术方案一致的，作为一个具体实施例，图4是包括基站的具体执行过程的数据调度方法的流程示意图。尽管这里描述的数据调度是基于图2所示的基站来执行，但需要注意的是，本发明实施例公开的数据调度方法的具体运行环境不仅限于上述基站。Consistent with the technical solutions described above, as a specific embodiment, FIG. 4 is a schematic flowchart of a data scheduling method including a specific execution process of a base station. Although the data scheduling described here is performed based on the base station shown in FIG. 2 , it should be noted that the specific operating environment of the data scheduling method disclosed in the embodiment of the present invention is not limited to the above-mentioned base station.

如图4所示，本发明方法实施例公开的数据调度方法具体包括以下步骤：As shown in FIG. 4 , the data scheduling method disclosed by the method embodiment of the present invention specifically includes the following steps:

S401、基站接收核心网发送的携带UE的能力信息的下行NAS传输信令；或者，基站接收UE发送的携带所述UE的能力信息的上行信息传输信令；所述基站向核心网发送携带有所述UE能力信息的上行NAS传输信令。S401. The base station receives the downlink NAS transmission signaling that carries the capability information of the UE sent by the core network; or the base station receives the uplink information transmission signaling that carries the capability information of the UE sent by the UE; the base station sends the information to the core network that carries the capability information of the UE. The uplink NAS transmission signaling of the UE capability information.

S402、所述基站根据所述UE的能力信息为所述UE分配数据调度资源。S402. The base station allocates data scheduling resources to the UE according to the capability information of the UE.

具体地，本发明实施例主要应用于CP传输数据的背景下，在UE与网络侧(基站或核心网)连接完成后，且基站与核心网连接完成后，若核心网有下行数据需要下发时，核心网在发送给基站的下行NAS传输信令除了包含NAS PDU外，可增加一个新的信元(informationelement，IE)，以用于传输上述UE的能力信息，这样使得核心网在发送下行数据的时候顺带将上述UE的能力信息发送给基站，进而减少了专用信令的使用，比如初始上下文建立请求信令等。或者，在UE与网络侧连接后，且UE与基站有上行数据传输时，UE在发送给基站的上行信息传输信令、NAS PDU中加入UE能力信息，传递给基站，基站将其发送给核心网，该过程可作为一个更新UE能力信息的过程。Specifically, the embodiments of the present invention are mainly applied in the context of data transmission by the CP. After the connection between the UE and the network side (base station or core network) is completed, and after the connection between the base station and the core network is completed, if the core network has downlink data that needs to be delivered When the core network sends the downlink NAS transmission signaling to the base station, in addition to the NAS PDU, a new information element (IE) can be added to transmit the capability information of the UE. When the data is generated, the capability information of the UE mentioned above is sent to the base station, thereby reducing the use of dedicated signaling, such as initial context establishment request signaling. Or, after the UE is connected to the network side, and when the UE and the base station have uplink data transmission, the UE adds the UE capability information to the uplink information transmission signaling and NAS PDU sent to the base station, and transmits it to the base station, and the base station sends it to the core. network, this process can be used as a process of updating UE capability information.

可选的，在RRC建立完成之后，基站可以在向核心网发送的初始UE上下文中携带指示信息以及携带寻找UE上下文的标识，该指示信息用于指示核心网向基站下发上述UE能力信息给基站。核心网收到该指示信息后，可在后续核心网向基站发送的下行信令中将上述UE的能力信息发送给基站，该信令名称本发明不做限定。Optionally, after the RRC is established, the base station may carry indication information and an identifier for finding the UE context in the initial UE context sent to the core network, where the indication information is used to instruct the core network to deliver the above UE capability information to the base station. base station. After the core network receives the indication information, it can send the capability information of the UE to the base station in the subsequent downlink signaling sent by the core network to the base station, and the name of the signaling is not limited in the present invention.

可选的，在基站发送给核心网初始UE上下文后，基站可通过向核心网发送的某一条信令向核心网索要上述UE的能力信息。可在后续核心网向基站发送的下行信令中将上述UE的能力信息发送给基站，该信令名称本发明不做限定。Optionally, after the base station sends the initial UE context to the core network, the base station may request the above-mentioned UE capability information from the core network through a certain signaling sent to the core network. The capability information of the UE may be sent to the base station in the subsequent downlink signaling sent by the core network to the base station, and the name of the signaling is not limited in the present invention.

可选的，核心网可通过向基站发送的下行数据中携带。Optionally, the core network may be carried in downlink data sent to the base station.

可选的，基站还无需指示核心网向基站发送UE的能力信息，核心网可直接通过某一条信令携带。Optionally, the base station does not need to instruct the core network to send the capability information of the UE to the base station, and the core network can directly carry it through a certain signaling.

可以看出，本发明实施例中，基站获取UE的能力信息是UE向基站发送的上行信令传输信令中携带的，或者核心网向基站发送的其他数据或者信令中携带，相较于现有技术的UE的能力信息是核心网向基站发送的专用信令(比如初始上下文建立请求信令)中携带的，可见，本发明实施例通过传输数据的同时携带UE的能力信息，节省了专用信令，进而降低了功耗。It can be seen that, in this embodiment of the present invention, the capability information that the base station acquires the UE is carried in the uplink signaling transmission signaling sent by the UE to the base station, or carried in other data or signaling sent by the core network to the base station. The capability information of the UE in the prior art is carried in the dedicated signaling (such as the initial context establishment request signaling) sent by the core network to the base station. It can be seen that in the embodiment of the present invention, by carrying the capability information of the UE while transmitting data, it saves money. Dedicated signaling, which in turn reduces power consumption.

与上述描述的技术方案一致的，作为一个具体实施例，图5是包括UE、基站以及核心网的具体执行过程的连接释放方法的流程示意图。尽管这里描述的数据调度是基于图2所示的UE、基站以及核心网来执行，但需要注意的是，本发明实施例公开的连接释放方法的具体运行环境不仅限于上述UE、基站以及核心网。Consistent with the technical solutions described above, as a specific embodiment, FIG. 5 is a schematic flowchart of a connection release method including specific execution processes of the UE, the base station and the core network. Although the data scheduling described here is performed based on the UE, base station, and core network shown in FIG. 2 , it should be noted that the specific operating environment of the connection release method disclosed in the embodiment of the present invention is not limited to the above-mentioned UE, base station, and core network. .

如图5所示，本发明方法实施例公开的连接释放方法具体包括以下步骤：As shown in FIG. 5 , the connection release method disclosed in the method embodiment of the present invention specifically includes the following steps:

S501、基站接收核心网发送的携带有连接释放指示的下行NAS传输信令。S501. The base station receives the downlink NAS transmission signaling that carries the connection release indication and is sent by the core network.

S502、所述基站向UE发送携带有所述连接释放指示的下行信息传输信令。S502. The base station sends the downlink information transmission signaling carrying the connection release indication to the UE.

S503、所述基站释放所述基站与所述UE的连接，并向所述核心网发送释放信令，以使得所述核心网接收到所述释放信令后释放S1接口。S503. The base station releases the connection between the base station and the UE, and sends release signaling to the core network, so that the core network releases the S1 interface after receiving the release signaling.

具体地，当上行传输完成数据传输时，可以在最后发送的NAS信息中添加释放辅助信息，指示是否需要下行数据反馈，当不需要下行反馈时，核心网接收数据后，核心网触发S1口释放流程。若上行指示需要下行反馈信息时，可以在核心网发送给基站的下行NAS传输信令增加一个IE指示基站在传输完数据后进行释放，并在该数据包传输的NAS PDU中添加连接释放指示，基站收到信息后，知道完成传输后进行释放操作。基站向UE发送携带有连接释放指示的下行信息传输信令，UE接到基站发送下行直传消息，根据NAS PDU中的指示信息进行释放。基站向UE发送携带有连接释放指示的下行信息传输信令后，向核心网发送释放信令，以使得核心网接收到该释放信令后释放S1接口，释放信令具体名称不限定。Specifically, when the uplink transmission completes the data transmission, the release auxiliary information can be added to the last sent NAS information to indicate whether downlink data feedback is required. When the downlink data feedback is not required, after the core network receives the data, the core network triggers the S1 port to release process. If the uplink indication requires downlink feedback information, an IE can be added to the downlink NAS transmission signaling sent by the core network to the base station to instruct the base station to release the data after the data is transmitted, and a connection release indication is added to the NAS PDU transmitted by the data packet. After the base station receives the information, it knows that the transmission is completed and the release operation is performed. The base station sends the downlink information transmission signaling carrying the connection release indication to the UE, and the UE receives the downlink direct transmission message sent by the base station, and releases according to the indication information in the NAS PDU. After sending the downlink information transmission signaling carrying the connection release indication to the UE, the base station sends the release signaling to the core network, so that the core network releases the S1 interface after receiving the release signaling. The specific name of the release signaling is not limited.

可选的，核心网向基站发送连接释放指示还可以是通过空口信令的MAC头中添加连接释放指示。Optionally, when the core network sends the connection release indication to the base station, the connection release indication may also be added to the MAC header of the air interface signaling.

可选的，当上行数据传输时，如果没有在上行包中进行指示需要包含释放指示信息的下行反馈，若在一段时间内没有数据传输，基站或者核心网可以触发释放连接，如果是基站触发的释放流程，则向UE发送释放指示信息后，向核心网进行S1口释放确认(指示)。如果是核心网触发的释放流程，则与现有释放UE上下文流程一样，在此不再叙述。Optionally, when uplink data is transmitted, if there is no indication in the uplink packet, the downlink feedback containing the release indication information needs to be included. If there is no data transmission for a period of time, the base station or the core network can trigger the release of the connection. If the base station triggers In the release process, after the release indication information is sent to the UE, the S1 port release confirmation (indication) is performed to the core network. If it is the release procedure triggered by the core network, it is the same as the existing procedure for releasing the UE context, and will not be described here.

可选的，当下行传输时，若核心网传输完一个数据包，则启动定时器，若定时器溢出，则进入正常释放连接流程。若需要上行反馈，则也可以走上述释放流程。若定时器没有溢出时，UE有上行包发出，则上述释放流程在此也可应用，即UE可以随时触发网络侧释放连接，也可以传输完数据后继续等待定时器溢出。若网络侧知道是最后一个数据包时，则也可在上述下行NAS传输信令中增加字段指示基站释放连接，在NAS PDU中添加释放指示信息，并由基站通过下行信息传输进行传递。Optionally, during downlink transmission, if the core network finishes transmitting a data packet, a timer is started, and if the timer overflows, a normal connection release process is entered. If uplink feedback is required, the above release process may also be followed. If the UE sends an uplink packet when the timer does not overflow, the above release process can also be applied here, that is, the UE can trigger the network side to release the connection at any time, or continue to wait for the timer to overflow after transmitting data. If the network side knows that it is the last data packet, it can also add a field to the above downlink NAS transmission signaling to instruct the base station to release the connection, add release indication information to the NAS PDU, and the base station transmits it through downlink information transmission.

可以看出，本发明实施例中，核心网向基站发送的连接释放指示是在核心网向基站发送的下行NAS传输信令携带的，相较于现有技术的连接释放指示是通过核心网向基站发送的专用信令中携带的，可见，本发明实施例通过传输数据的同时携带连接释放指示，节省了专用信令，进而降低了功耗。It can be seen that, in the embodiment of the present invention, the connection release indication sent by the core network to the base station is carried in the downlink NAS transmission signaling sent by the core network to the base station. It is carried in the dedicated signaling sent by the base station. It can be seen that the embodiment of the present invention saves the dedicated signaling by carrying the connection release indication while transmitting the data, thereby reducing the power consumption.
