Into this article.

技术领域Technical field

本申请涉及通信技术领域，尤其涉及一种辅基站变更方法、主基站、辅基站和终端。This application relates to the field of communication technologies, and in particular to a method for changing a secondary base station, a primary base station, a secondary base station, and a terminal.

背景技术Background technique

随着网络的不断演进，传统网络架构下的节点间移动事件已经无法满足针对移动性能提出的更高需求。例如，在普通的移动场景中，当终端移动到两个网络实体的信号覆盖交叠处后，网络将触发移动性事件。此时，传统的切换流程所采用的是先中断源侧的数据传输，并在接入到目标基站后再继续业务传输，从而导致较大的数据中断；而在条件切换流程中，则是在主基站上产生条件切换的触发条件，在条件辅基站添加/变更(conditional SN addition/change)的操作中，根据主基站(Master Node，MN)产生的触发条件执行辅基站发起的SN change过程，但是这会影响系统的移动性性能，使得SN change的执行无法很好的适应SN本身的无线资源管理(Radio Resource Management，RRM)策略。With the continuous evolution of the network, the movement events between nodes under the traditional network architecture can no longer meet the higher requirements for mobile performance. For example, in a common mobile scenario, when the terminal moves to a place where the signal coverage of two network entities overlap, the network will trigger a mobility event. At this time, the traditional handover process uses the first interruption of the source side data transmission, and then continues the service transmission after accessing the target base station, which leads to a large data interruption; while in the conditional handover process, it is The trigger condition for conditional handover is generated on the primary base station. In the conditional SN addition/change operation, the SN change process initiated by the secondary base station is executed according to the trigger condition generated by the primary base station (Master Node, MN), However, this will affect the mobility performance of the system, making the execution of SN change not well adapted to the SN's own radio resource management (Radio Resource Management, RRM) strategy.

综上，在现有技术中，双连接或多连接情况下，辅基站(Secondary Node，SN)的变更依赖网络的配置消息执行操作，从而导致不必要的数据中断时延。To sum up, in the prior art, in the case of dual connection or multiple connection, the change of the secondary base station (Secondary Node, SN) depends on the configuration message of the network to perform operations, which causes unnecessary data interruption time delay.

具体实施方式Detailed ways

为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the protection scope of this application.

目前只能在MN产生条件切换的触发条件，而在conditional SN addition/change的操作中，根据MN产生的触发条件执行辅节点发起的SN change过程，将影响系统的移动性能，使得SN change的执行无法很好适应SN本身的RRM策略。At present, the conditional switching trigger conditions can only be generated in the MN. In the conditional SN addition/change operation, the SN change process initiated by the secondary node is executed according to the trigger conditions generated by the MN, which will affect the mobile performance of the system and make the SN change execution Cannot adapt well to the RRM strategy of SN itself.

针对此，本申请实施例为了支持conditional SN change机制，允许源SN生成SN change的触发条件，这个触发条件用于终端进行SN change时的判断准则，实现了由源SN产生的触发条件执行SN发起的SN change过程，从而避免了现有技术中由MN产生的触发条件执行辅节点发起的SN change过程时，导致的影响系统的移动性能的问题。下面通过具体实施例对本申请进行具体介绍。In response to this, in order to support the conditional SN change mechanism, this embodiment of the application allows the source SN to generate a trigger condition for SN change. This trigger condition is used as a criterion when the terminal performs an SN change, and implements the trigger condition generated by the source SN to execute SN initiation The SN change process avoids the problem of affecting the mobility performance of the system when the trigger condition generated by the MN executes the SN change process initiated by the secondary node in the prior art. The application will be specifically introduced below through specific embodiments.

如图1所示，为本申请实施例中应用于源SN的辅基站变更方法的步骤流程图，该方法包括如下步骤：As shown in Fig. 1, this is a flowchart of the steps of a method for changing a secondary base station applied to a source SN in an embodiment of this application. The method includes the following steps:

步骤101：配置辅基站变更SN change触发条件。Step 101: Configure the secondary base station to change the SN change trigger condition.

具体的，终端与MN和源SN保持双连接。Specifically, the terminal maintains dual connections with the MN and the source SN.

在本步骤中，源SN可以自己配置SN change触发条件。In this step, the source SN can configure the SN change trigger condition by itself.

具体的，该SN change触发条件可以为目标小区的信号强度。例如参考信号接收功率(Reference Signal Receiving Power，RSRP)或参考信号接收质量(Reference Signal Receiving Quality，RSRQ)等，还可以为A3/A5/A4或B1等测量事件的门限值等，在此不对此进行具体限定。Specifically, the SN change trigger condition may be the signal strength of the target cell. For example, reference signal receiving power (Reference Signal Receiving Power, RSRP) or reference signal receiving quality (Reference Signal Receiving Quality, RSRQ), etc., can also be the threshold of measurement events such as A3/A5/A4 or B1, etc., which is not correct here This is specifically limited.

步骤102：将SN change触发条件发送给MN。Step 102: Send the SN change trigger condition to the MN.

在本步骤中，具体的，源SN可以将SN change触发条件发送给MN，从而使得MN能够将该SN change触发条件发送给终端，进而由终端根据SN change触发条件确定是否执行SN change操作。In this step, specifically, the source SN can send the SN change trigger condition to the MN, so that the MN can send the SN change trigger condition to the terminal, and the terminal determines whether to perform the SN change operation according to the SN change trigger condition.

这样，通过源SN自身配置SN change触发条件，并将SN change触发条件发送给MN，并由MN将SN change触发条件发送给终端，使得源SN能够通过自身所产生的SN change触发条件执行自身所发起的SN change过程，进而避免了现有技术中基于MN产生的SN change触发条件执行SN发起的SN change过程时，导致的数据中断时延。In this way, the source SN itself configures the SN change trigger condition and sends the SN change trigger condition to the MN, and the MN sends the SN change trigger condition to the terminal, so that the source SN can execute its own changes through the SN change trigger condition generated by itself. The initiated SN change process further avoids the data interruption time delay caused when the SN change process initiated by the SN is executed based on the SN change trigger condition generated by the MN in the prior art.

此外，具体的，在配置SN change触发条件时，可以针对不同的目标SN小区，配置SN change触发条件；或者，针对不同的目标载频，配置SN change触发条件。In addition, specifically, when configuring SN change trigger conditions, SN change trigger conditions can be configured for different target SN cells; or, SN change trigger conditions can be configured for different target carrier frequencies.

即可以将目标SN小区作为SN change触发条件的配置单元，从而使得可以对不同的目标SN小区配置不同的SN change触发条件；还可以将目标载频作为SN change触发条件的配置单元，从而使得可以对不同的目标载频配置不同的SN change触发条件，此时基于多个目标SN小区可能对应相同的目标载频，则该些多个目标SN小区则会对应相同的SN change触发条件。That is, the target SN cell can be used as the configuration unit of the SN change trigger condition, so that different target SN cells can be configured with different SN change trigger conditions; the target carrier frequency can also be used as the configuration unit of the SN change trigger condition, so that Different SN change trigger conditions are configured for different target carrier frequencies. In this case, based on the fact that multiple target SN cells may correspond to the same target carrier frequency, these multiple target SN cells will correspond to the same SN change trigger condition.

另外，具体的，在配置SN change触发条件时，可以对同一个目标SN小区，配置至少一个SN change触发条件；或者，对同一个目标载频，配置至少一个SN change触发条件。In addition, specifically, when configuring the SN change trigger condition, at least one SN change trigger condition can be configured for the same target SN cell; or, for the same target carrier frequency, at least one SN change trigger condition can be configured.

即可以对同一个目标SN小区配置一个或多个SN change触发条件，对同一个目标载频配置一个或多个SN change触发条件，在此并不具体限定针对每个目标SN小区或每个目标载频所配置的SN change触发条件的数量。That is, one or more SN change trigger conditions can be configured for the same target SN cell, and one or more SN change trigger conditions can be configured for the same target carrier frequency. This is not specifically limited to each target SN cell or each target. The number of SN change trigger conditions configured by the carrier frequency.

另外，进一步地，本实施例在将SN change触发条件发送给MN时，可以针对源SN发起的SN change过程是外部过程还是源SN内部过程，定义不同的发送方式，在此进行具体说明。In addition, further, when the SN change trigger condition is sent to the MN in this embodiment, different sending modes can be defined for whether the SN change process initiated by the source SN is an external process or an internal process of the source SN, which will be described in detail here.

其一，在将SN change触发条件发送给MN时，向所述MN发送第一请求消息，其中所述第一请求消息中携带有源SN预先获取的候选目标SN列表以及所述候选目标SN列表的SN change触发条件列表；First, when the SN change trigger condition is sent to the MN, a first request message is sent to the MN, where the first request message carries a list of candidate target SNs and the list of candidate target SNs obtained in advance by the active SN List of SN change trigger conditions;

所述SN change触发条件列表中包括候选目标SN的SN change触发条件和/或所述候选目标SN下候选SN小区的SN change触发条件。The SN change trigger condition list includes the SN change trigger condition of the candidate target SN and/or the SN change trigger condition of the candidate SN cell under the candidate target SN.

具体的，该第一请求消息可以为SN变更请求(SN change required)消息，当然在此并不对此进行具体限定。Specifically, the first request message may be an SN change request (SN change required) message, which of course is not specifically limited here.

此外，具体的，源SN可以预先获取到其他的SN列表，即可以获取到能够作为候选切换的目标SN列表，此时源SN可以将所预先获取到的候选目标SN列表以及该候选目标SN列表所对应的SN change触发条件列表携带于第一消息中，发送给MN。In addition, specifically, the source SN may obtain a list of other SNs in advance, that is, it may obtain a list of target SNs that can be used as candidates for handover. At this time, the source SN may compile the list of candidate target SNs obtained in advance and the list of candidate target SNs. The corresponding SN change trigger condition list is carried in the first message and sent to the MN.

另外，具体的，候选目标SN列表的SN change触发条件列表可以为，候选目标SN列表中每个候选目标SN所对应的SN触发条件，和/或每个候选目标SN下每个候选SN小区所对应的SN change触发条件。In addition, specifically, the SN change trigger condition list of the candidate target SN list may be the SN trigger condition corresponding to each candidate target SN in the candidate target SN list, and/or each candidate SN cell location under each candidate target SN. Corresponding SN change trigger condition.

当然，需要说明的是，每个候选目标SN或每个候选SN小区所对应的SN触发条件的个数在此并不进行限制，可以为一个或多个。Of course, it should be noted that the number of SN trigger conditions corresponding to each candidate target SN or each candidate SN cell is not limited here, and may be one or more.

通过上述方式，使得在源SN将第一消息发送给MN时，MN能够获取针对每个候选目标SN或针对每个候选SN小区的SN change触发条件，从而使得能够实现与其他SN之间的外部SN change过程。Through the above method, when the source SN sends the first message to the MN, the MN can obtain the SN change trigger condition for each candidate target SN or for each candidate SN cell, thereby enabling external communication with other SNs. SN change process.

其二，在将SN change触发条件发送给MN时，向所述MN发送第二请求消息，其中所述第二请求消息中携带有源SN下的候选目标小区列表、所述候选目标小区列表中候选目标小区的SN change触发条件以及所述候选目标小区的配置信息。Second, when the SN change trigger condition is sent to the MN, a second request message is sent to the MN, where the second request message carries the list of candidate target cells under the active SN and the list of candidate target cells The SN change trigger condition of the candidate target cell and the configuration information of the candidate target cell.

具体的，该第二请求消息可以为SN修改请求(SN Modification required)消息，当然在此并不对此进行具体限定。Specifically, the second request message may be an SN Modification required (SN Modification required) message, which of course is not specifically limited here.

此外，具体的，基于源SN下有多个辅小区，此时在源SN需要发起内部SN变更(intra-SN change)时，源SN可以获取源SN下除当前连接小区之外的其他至少一个辅小区，即获取能够作为候选切换小区的候选目标小区列表，并将该候选目标小区列表中每个候选目标小区的SN change触发条件以及候选目标小区的配置信息携带于第二消息中，发送给MN。In addition, specifically, based on the source SN having multiple secondary cells, when the source SN needs to initiate an internal SN change (intra-SN change), the source SN can obtain at least one other cell in the source SN except the currently connected cell Secondary cell, that is, obtain a list of candidate target cells that can be used as candidate handover cells, and carry the SN change trigger condition of each candidate target cell in the candidate target cell list and the configuration information of the candidate target cell in the second message, and send it to MN.

当然，需要说明的是，每个候选目标小区所对应的SN触发条件的个数在此并不进行限制，可以为一个或多个。Of course, it should be noted that the number of SN trigger conditions corresponding to each candidate target cell is not limited here, and may be one or more.

通过上述方式，使得在源SN将第二消息发送给MN时，MN能够获取源SN下每个候选目标小区的SN change触发条件，从而使得能够实现源SN下的内部SN change过程。Through the above method, when the source SN sends the second message to the MN, the MN can obtain the SN change trigger condition of each candidate target cell under the source SN, so that the internal SN change process under the source SN can be realized.

另外，在向MN发送第二请求消息之后，还可以接收所述MN发送的第三请求消息，其中所述第三请求消息中携带有所述候选目标小区的安全密钥信息；然后向所述MN发送指示完成安全密钥信息接收的确认消息。从而使得能够保证数据传输的安全性。In addition, after the second request message is sent to the MN, a third request message sent by the MN may also be received, where the third request message carries the security key information of the candidate target cell; The MN sends a confirmation message indicating that the reception of the security key information is completed. This makes it possible to ensure the security of data transmission.

具体的，第三请求消息可以为SN modification request消息，在此并不对第三请求消息的具体形式进行限定。Specifically, the third request message may be an SN modification request message, and the specific form of the third request message is not limited here.

通过上述两种方式中的任一种方式将SN change触发条件发送给MN，保证了在源SN自身配置SN change触发条件时SN change过程的顺利进行。Sending the SN change trigger condition to the MN in either of the above two ways ensures the smooth progress of the SN change process when the source SN itself configures the SN change trigger condition.

此外，应理解，本实施例中所提到的“每个”是对候选目标SN、候选SN小区或候选目标小区的说明，而不构成对其的限定。In addition, it should be understood that the "each" mentioned in this embodiment is an explanation of a candidate target SN, a candidate SN cell, or a candidate target cell, and does not constitute a limitation thereof.

这样，本实施例通过源SN自身配置SN change触发条件，并将SN change触发条件发送给MN，并由MN将SN change触发条件发送给终端，使得源SN能够通过自身所产生的SN change触发条件执行自身所发起的SN change过程，进而避免了现有技术中基于MN产生的SN change触发条件执行SN发起的SN change过程时的数据中断时延。In this way, in this embodiment, the source SN itself configures the SN change trigger condition and sends the SN change trigger condition to the MN, and the MN sends the SN change trigger condition to the terminal, so that the source SN can use the SN change trigger condition generated by itself Execute the SN change process initiated by itself, thereby avoiding the data interruption time delay when the SN change process initiated by the SN is executed based on the SN change trigger condition generated by the MN in the prior art.

此外，如图2所示，为本申请实施例中应用于MN的辅基站的变更方法的步骤流程图，该方法包括如下步骤：In addition, as shown in FIG. 2, it is a flow chart of the steps of the method for changing the secondary base station applied to the MN in the embodiment of this application, and the method includes the following steps:

步骤201：接收源SN所发送的SN change触发条件；Step 201: Receive the SN change trigger condition sent by the source SN;

具体的，终端与MN和源SN保持双连接操作。Specifically, the terminal maintains a dual connection operation with the MN and the source SN.

此外，具体的，MN可以接收源SN发送的SN change触发条件，即SN change触发条件可以由源SN自身进行配置，并发送给MN。In addition, specifically, the MN can receive the SN change trigger condition sent by the source SN, that is, the SN change trigger condition can be configured by the source SN itself and sent to the MN.

步骤202：将SN change触发条件发送给终端，以使终端根据SN change触发条件确定是否执行SN change操作。Step 202: Send the SN change trigger condition to the terminal, so that the terminal determines whether to perform the SN change operation according to the SN change trigger condition.

具体的，MN在接收到源SN发送的SN change触发条件之后，可以将SN change触发条件发送给终端，进而由终端根据SN change触发条件确定是否执行SN change操作。Specifically, after receiving the SN change trigger condition sent by the source SN, the MN may send the SN change trigger condition to the terminal, and the terminal determines whether to perform the SN change operation according to the SN change trigger condition.

此外，进一步地，MN在接收源SN发送的SN change触发条件时，可以通过下述两种方式中的任一种方式：In addition, further, when the MN receives the SN change trigger condition sent by the source SN, it can use any of the following two methods:

其一，接收源SN发送的第一请求消息，其中所述第一请求消息中携带有所述源SN预先获取的候选目标SN列表以及所述候选目标SN列表的SN change触发条件列表；One is to receive a first request message sent by a source SN, where the first request message carries a list of candidate target SNs obtained in advance by the source SN and a list of SN change trigger conditions of the candidate target SN list;

具体的，该实施例中第一请求消息的具体内容可以参见上述源SN侧方法实施例中的具体介绍，在此不再进行赘述。Specifically, for the specific content of the first request message in this embodiment, reference may be made to the specific introduction in the foregoing source SN-side method embodiment, which will not be repeated here.

此外，具体的，MN在接收第一请求消息时，可以对该第一请求消息中所携带的候选目标SN列表以及所述候选目标SN列表的SN change触发条件列表进行保存操作，从而使得MN能够从所保存的候选目标SN列表以及候选目标SN列表的SN change触发条件列表中查找到所需要的信息。In addition, specifically, when the MN receives the first request message, it can save the candidate target SN list and the SN change trigger condition list of the candidate target SN list carried in the first request message, so that the MN can Find the required information from the saved candidate target SN list and the SN change trigger condition list of the candidate target SN list.

此外，在此说明的是，MN在接收源SN发送的第一请求消息之后，可以向候选目标SN列表中的候选目标SN发送第四请求消息；然后接收候选目标SN根据第四请求消息所反馈的响应消息，其中响应消息中携带有候选目标SN下候选SN小区的配置信息；并根据候选SN小区的配置信息，从候选目标SN列表的SN change触发条件列表中，获取候选SN小区所对应的SN change触发条件。In addition, it is explained here that after receiving the first request message sent by the source SN, the MN may send a fourth request message to the candidate target SN in the candidate target SN list; and then receive the feedback from the candidate target SN according to the fourth request message. The response message contains the configuration information of the candidate SN cell under the candidate target SN; and according to the configuration information of the candidate SN cell, from the SN change trigger condition list of the candidate target SN list, the candidate SN cell corresponding to the SN change trigger condition.

具体的，第四请求消息可以为SN添加请求(SN addition request)消息，响应消息可以为SN addition request Ack消息，当然在此并不对该第四请求消息和响应消息的具体形式进行限定。Specifically, the fourth request message may be an SN addition request (SN addition request) message, and the response message may be an SN addition request Ack message. Of course, the specific forms of the fourth request message and the response message are not limited here.

另外，具体的，MN在向每个候选目标SN发送第四请求消息后，候选目标SN将执行接纳控制，并选择合适的候选SN小区，然后向SN反馈响应消息，当然该SN响应消息中携带有候选SN小区的配置信息；此时，MN可以通过该响应消息中所携带的候选SN小区的配置信息，从先获取到的SN change触发条件列表中获取候选SN小区所对应的SN change触发条件。In addition, specifically, after the MN sends the fourth request message to each candidate target SN, the candidate target SN will perform admission control, select a suitable candidate SN cell, and then feed back a response message to the SN. Of course, the SN response message carries There is the configuration information of the candidate SN cell; at this time, the MN can obtain the SN change trigger condition corresponding to the candidate SN cell from the SN change trigger condition list obtained first through the configuration information of the candidate SN cell carried in the response message .

其二，接收源SN发送的第二请求消息，其中第二请求消息中携带有源SN下的候选目标小区列表、候选目标小区列表中候选目标小区的SN change触发条件以及候选目标小区的配置信息。Second, receiving the second request message sent by the source SN, where the second request message carries the candidate target cell list under the active SN, the SN change trigger condition of the candidate target cell in the candidate target cell list, and the configuration information of the candidate target cell .

具体的，该实施例中第二请求消息的具体内容可以参见上述源SN侧方法实施例中的具体介绍，在此不再进行赘述。Specifically, for the specific content of the second request message in this embodiment, reference may be made to the specific introduction in the foregoing source SN-side method embodiment, and details are not described herein again.

此外，具体的，MN在接收第二请求消息时，可以对该第二请求消息中所携带的候选目标小区列表中每个候选目标小区的SN change触发条件以及候选目标小区的配置信息进行保存操作，从而使得MN能够从所保存的每个候选目标小区的SN change触发条件以及候选目标小区的配置信息中查找到需要的信息。In addition, specifically, when receiving the second request message, the MN can save the SN change trigger condition of each candidate target cell in the candidate target cell list carried in the second request message and the configuration information of the candidate target cell. , So that the MN can find the required information from the saved SN change trigger conditions of each candidate target cell and the configuration information of the candidate target cell.

此外，在此需要说明的是，MN在接收源SN发送的第二请求消息之后，可以向源SN发送第三请求消息，其中第三请求消息中携带有候选目标小区的安全密钥信息；然后接收所述源SN发送的指示完成安全密钥信息接收的第一确认消息。In addition, it should be noted here that after receiving the second request message sent by the source SN, the MN may send a third request message to the source SN, where the third request message carries the security key information of the candidate target cell; Receiving a first confirmation message sent by the source SN indicating completion of receiving the security key information.

具体的，该实施例中第三请求消息的具体内容可以参见上述源SN侧方法实施例中的具体介绍，在此不再进行赘述。Specifically, for the specific content of the third request message in this embodiment, reference may be made to the specific introduction in the foregoing source SN-side method embodiment, which will not be repeated here.

这样，通过上述两种方式中的任一种方式接收源SN所发送的SN change触发条件，保证了在源SN自身配置SN change触发条件时SN change过程的顺利进行。In this way, receiving the SN change trigger condition sent by the source SN in either of the above two ways ensures the smooth progress of the SN change process when the source SN itself configures the SN change trigger condition.

另外，进一步地，本实施例还可以在接收候选目标SN所反馈的响应消息或接收源SN发送的第二请求消息之后，向终端发送无线资源控制(RRC)重配置消息，其中所述RRC重配置消息中携带有所述候选SN小区的配置信息和与其相对应的SN change触发条件，或者携带有所述候选目标小区的配置信息和与其相对应的SN change触发条件。In addition, further, this embodiment may also send a radio resource control (RRC) reconfiguration message to the terminal after receiving the response message fed back by the candidate target SN or the second request message sent by the source SN, where the RRC reconfiguration message The configuration message carries the configuration information of the candidate SN cell and the corresponding SN change trigger condition, or carries the configuration information of the candidate target cell and the corresponding SN change trigger condition.

即，SN可以将先获取到的候选SN小区的配置信息和与其相对应的SN change触发条件组合成一条RRC重配置消息，即此时RRC重配置消息中携带的为候选SN小区的配置信息和与其相对应的SN change触发条件，并将该RRC重配置消息发送至终端，从而使得终端能够获知每个候选SN小区所对应的SN change触发条件；That is, the SN can combine the configuration information of the candidate SN cell acquired first and the corresponding SN change trigger condition into one RRC reconfiguration message, that is, the configuration information and the configuration information of the candidate SN cell carried in the RRC reconfiguration message at this time The corresponding SN change trigger condition, and the RRC reconfiguration message is sent to the terminal, so that the terminal can learn the SN change trigger condition corresponding to each candidate SN cell;

当然，SN还可以将先获取到的源SN下的候选目标小区的配置信息和与其相对应的SN change触发条件组合成一条RRC重配置消息，即此时RRC重配置消息中所携带的为候选目标小区的配置信息和与其相对应的SN change触发条件，并将该RRC重配置消息发送至终端，从而使得终端能够获知源SN下每个候选目标小区所对应的SN change触发条件。Of course, the SN can also combine the configuration information of the candidate target cell under the source SN obtained first and the corresponding SN change trigger condition into an RRC reconfiguration message, that is, the RRC reconfiguration message carries the candidate at this time. The configuration information of the target cell and the corresponding SN change trigger condition, and the RRC reconfiguration message is sent to the terminal, so that the terminal can learn the SN change trigger condition corresponding to each candidate target cell under the source SN.

此外，具体的，MN可以通过信令无线承载(SRB1)将RRC重配置消息发送给终端。In addition, specifically, the MN can send the RRC reconfiguration message to the terminal through the signaling radio bearer (SRB1).

当然，在此需要说明的是，MN还可以接收终端所反馈的RRC重配置完成消息，以确定终端已成功接收到RRC重配置消息。Of course, it should be noted here that the MN may also receive the RRC reconfiguration complete message fed back by the terminal to determine that the terminal has successfully received the RRC reconfiguration message.

另外，在向终端发送RRC重配置消息之后，可以接收终端在执行SN change操作后所发送的RRC消息，其中RRC消息中携带有指示SN配置成功的指示信息和变更后的目标SN的标识信息；然后向目标SN发送指示配置成功的第二确认消息。从而使得能够进入终端与目标SN之间的接入过程。In addition, after sending the RRC reconfiguration message to the terminal, the RRC message sent by the terminal after performing the SN change operation can be received, where the RRC message carries indication information indicating that the SN configuration is successful and the identification information of the target SN after the change; Then, a second confirmation message indicating that the configuration is successful is sent to the target SN. Thus, it is possible to enter the access process between the terminal and the target SN.

此外，在此需要说明的是，目标SN可以为候选目标SN或源SN，即当变更后的小区为候选SN小区时，目标SN为源SN之外的候选目标SN，当变更后的小区为源SN下的候选目标小区时，目标SN为源SN。In addition, it should be noted here that the target SN can be a candidate target SN or a source SN, that is, when the changed cell is a candidate SN cell, the target SN is a candidate target SN other than the source SN, and when the changed cell is When a candidate target cell is under the source SN, the target SN is the source SN.

此外，应理解，本实施例中所提到的“每个”是对候选目标SN、候选SN小区或候选目标小区的说明，即是对实施例的说明，而不构成对其的限定。In addition, it should be understood that the "each" mentioned in this embodiment is an explanation of a candidate target SN, a candidate SN cell, or a candidate target cell, that is, an explanation of the embodiment, and does not constitute a limitation thereof.

这样，本实施例通过接收源SN所发送的SN change触发条件，并将SN change触发条件发送给终端，由终端根据SN change触发条件确定是否执行SN change操作，实现了由源SN自身配置SN change触发条件，从而使得源SN能够通过自身所产生的SN change触发条件执行自身所发起的SN change过程，进而避免了现有技术中基于MN产生的SN change触发条件执行SN发起的SN change过程时的数据中断时延。In this way, this embodiment receives the SN change trigger condition sent by the source SN and sends the SN change trigger condition to the terminal. The terminal determines whether to perform the SN change operation according to the SN change trigger condition, so that the source SN itself configures the SN change Trigger condition, so that the source SN can execute the SN change process initiated by itself through the SN change trigger condition generated by itself, thereby avoiding the SN change process initiated by the SN based on the SN change trigger condition generated by the MN in the prior art. Data interruption time delay.

此外，如图3所示，为应用于终端的辅基站变更方法的步骤流程图，该方法包括如下步骤：In addition, as shown in FIG. 3, it is a flowchart of steps of a method for changing a secondary base station applied to a terminal, and the method includes the following steps:

步骤301：接收MN所发送的SN change触发条件。Step 301: Receive the SN change trigger condition sent by the MN.

在本步骤中，终端接收MN所发送的SN change触发条件，该SN change触发条件由源SN配置得到。In this step, the terminal receives the SN change trigger condition sent by the MN, and the SN change trigger condition is configured by the source SN.

具体的，终端在接收MN所发送的SN change触发条件时，可以接收MN所发送的RRC重配置消息，其中RRC重配置消息中携带有候选SN小区的配置信息和与其相对应的SN change触发条件，或者携带有候选目标小区的配置信息和与其相对应的SN change触发条件；所述候选 SN小区为候选目标SN下的小区，所述候选目标小区为源SN下的小区。Specifically, when the terminal receives the SN change trigger condition sent by the MN, it can receive the RRC reconfiguration message sent by the MN, where the RRC reconfiguration message carries the configuration information of the candidate SN cell and the corresponding SN change trigger condition , Or carry the configuration information of the candidate target cell and the corresponding SN change trigger condition; the candidate SN cell is a cell under the candidate target SN, and the candidate target cell is a cell under the source SN.

在此需要说明的是，上述RRC重配置消息的具体介绍可以参见上述MN侧方法实施例中对RRC重配置消息的说明，在此不再进行赘述。It should be noted here that, for the specific introduction of the foregoing RRC reconfiguration message, reference may be made to the description of the RRC reconfiguration message in the foregoing MN-side method embodiment, which is not repeated here.

当然，终端在接收RRC重配置消息之后，可以向MN反馈RRC重配置完成消息。Of course, after receiving the RRC reconfiguration message, the terminal can feed back the RRC reconfiguration complete message to the MN.

步骤302：根据SN change触发条件，确定是否执行SN change操作。Step 302: Determine whether to perform the SN change operation according to the SN change trigger condition.

在本步骤中，具体的，终端在接收到MN所发送的SN change触发条件之后，可以基于该SN change触发条件，确定是否执行SN change操作。In this step, specifically, after receiving the SN change trigger condition sent by the MN, the terminal may determine whether to perform the SN change operation based on the SN change trigger condition.

具体的，终端在根据该SN change触发条件确定是否执行SN change操作时，可以当确定候选SN小区或候选目标小区满足相对应的SN change触发条件时，将候选SN小区或候选目标小区所对应的SN确定为目标SN，并执行SN change操作。Specifically, when the terminal determines whether to perform an SN change operation according to the SN change triggering condition, it may determine that the candidate SN cell or the candidate target cell meets the corresponding SN change triggering condition, and the candidate SN cell or the candidate target cell corresponding to the The SN is determined as the target SN, and the SN change operation is executed.

并在执行SN change操作之后，向MN发送RRC消息，其中RRC消息中携带有指示SN配置成功的指示信息和变更后的目标SN的标识信息，从而使得MN能够根据该RRC消息，向目标SN发送指示配置成功的确认消息，进而完成终端与目标SN之间的接入过程。And after performing the SN change operation, send an RRC message to the MN, where the RRC message carries indication information indicating that the SN configuration is successful and the identification information of the target SN after the change, so that the MN can send to the target SN according to the RRC message A confirmation message indicating that the configuration is successful, thereby completing the access process between the terminal and the target SN.

这样，在本实施例中，终端接收MN所发送的由源SN所配置的change触发条件，并根据该SN change触发条件，确定是否执行SN change操作，实现了由源SN自身配置SN change触发条件，从而使得源SN能够通过自身所产生的SN change触发条件执行自身所发起的SN change过程，进而避免了现有技术中基于MN产生的SN change触发条件执行SN发起的SN change过程时的数据中断时延。In this way, in this embodiment, the terminal receives the change trigger condition configured by the source SN sent by the MN, and determines whether to perform the SN change operation according to the SN change trigger condition, so that the source SN itself configures the SN change trigger condition Therefore, the source SN can execute the SN change process initiated by itself through the SN change trigger condition generated by itself, thereby avoiding the data interruption when the SN change process initiated by the SN is executed based on the SN change trigger condition generated by the MN in the prior art Time delay.

下面通过具体示例对上述实施例进行说明。The above-mentioned embodiments will be described below through specific examples.

示例一，如图4所示，针对源SN发起的SN change过程：Example 1, as shown in Figure 4, the SN change process initiated by the source SN:

其中，终端与MN和源SN保持双连接操作；Among them, the terminal maintains dual-connection operation with the MN and the source SN;

此时，源SN可以向MN发送SN change required消息，该SN change required消息中携带候选目标SN列表以及候选目标SN列表的SN change触发条件列表，当然，该SN change触发条件列表中包括每个候选目标SN的SN change触发条件和/或候选目标SN下每个候选SN小区的SN change触发条件。At this time, the source SN can send an SN change required message to the MN. The SN change required message carries the candidate target SN list and the SN change trigger condition list of the candidate target SN list. Of course, the SN change trigger condition list includes each candidate The SN change trigger condition of the target SN and/or the SN change trigger condition of each candidate SN cell under the candidate target SN.

然后，MN保存该SN change required消息中所携带的候选目标SN列表以及候选目标SN列表的SN change触发条件列表，并向候选目标SN发送SN addition request消息；Then, the MN saves the candidate target SN list and the SN change trigger condition list of the candidate target SN list carried in the SN change required message, and sends an SN addition request message to the candidate target SN;

再然后，候选目标SN将执行接纳控制，选择合适候选SN小区，并返回SN addition request Ack消息，当然该SN addition request Ack中携带有候选SN小区的配置信息；Then, the candidate target SN will perform admission control, select a suitable candidate SN cell, and return an SN addition request Ack message. Of course, the SN addition request Ack carries the configuration information of the candidate SN cell;

再然后，MN根据接收到的来自候选目标SN的配置信息，查找到相对应的SN change变更条件，并将候选SN小区和与其相对应的SN change触发条件组合成一条新的RRC重配置消息，并将该RRC重配置消息通过MN的SRB发送给终端；Then, the MN finds the corresponding SN change condition according to the received configuration information from the candidate target SN, and combines the candidate SN cell and the corresponding SN change trigger condition into a new RRC reconfiguration message. And send the RRC reconfiguration message to the terminal through the SRB of the MN;

再然后，终端向MN反馈RRC重配置完成消息；Then, the terminal feeds back an RRC reconfiguration complete message to the MN;

此时，当终端根据所接收到的SN change变更条件，判断得到候选SN小区满足该SN change变更条件时，将执行SN change操作，并向MN发送携带有指示SN配置成功的指示信息和变更后的目标SN的标识信息的RRC消息，当然该目标SN即为终端所满足的SN change变更条件所对应的候选目标SN。At this time, when the terminal judges that the candidate SN cell satisfies the SN change condition according to the received SN change condition, it will execute the SN change operation and send to the MN the indication information that indicates that the SN configuration is successful. Of course, the target SN is the candidate target SN corresponding to the SN change condition satisfied by the terminal.

再然后，MN向目标SN发送指示配置成功的确认消息，且终端与目标SN之间完成接入过程。Then, the MN sends a confirmation message indicating that the configuration is successful to the target SN, and the access process is completed between the terminal and the target SN.

示例二，如图5所示，针对源SN发起的内部SN change过程：Example two, as shown in Figure 5, the internal SN change process initiated by the source SN:

此时，源SN可以向MN发送SN Modification required消息，该SN Modification required消息中携带有源SN下的候选目标小区列表、候选目标小区列表中每个候选目标小区的SN change触发条件以及候选目标小区的配置信息。At this time, the source SN can send an SN Modification required message to the MN. The SN Modification required message carries the list of candidate target cells under the active SN, the SN change trigger condition of each candidate target cell in the candidate target cell list, and the candidate target cell. Configuration information.

然后，MN保存该SN Modification required消息所携带的候选目标小区列表、候选目标小区列表中每个候选目标小区的SN change触发条件以及候选目标小区的配置信息；Then, the MN saves the candidate target cell list carried in the SN Modification required message, the SN change trigger condition of each candidate target cell in the candidate target cell list, and the configuration information of the candidate target cell;

再然后，MN向源SN发送SN modification request消息，该SN modification request消息中携带有每个候选目标小区的安全密钥信息的安全密钥信息；Then, the MN sends an SN modification request message to the source SN, and the SN modification request message carries the security key information of the security key information of each candidate target cell;

再然后，源SN返回指示完成安全密钥信息接收的确认消息；Then, the source SN returns a confirmation message indicating the completion of receiving the security key information;

再然后，MN将候选目标小区的配置信息和与其相对应的SN change触发条件组合成一条新的RRC重配置消息，并将该RRC重配置消息通过MN的SRB1发送给终端；Then, the MN combines the configuration information of the candidate target cell and the corresponding SN change trigger condition into a new RRC reconfiguration message, and sends the RRC reconfiguration message to the terminal through the MN's SRB1;

在此需要说明的是，当候选目标小区不需要更新安全密钥信息时，可以省略MN向源SN发送上述SN modification request消息的步骤，即省略安全密钥信息的发送步骤，直接进入该向终端发送RRC重配置消息的步骤；此外，MN还可以在向源SN发送SN modification request消息之后，随后向终端发送RRC重配置消息，而不用再等待接收到源SN返回指示完成安全密钥信息接收的确认消息之后再发送，以节省SN变更时间。It should be noted here that when the candidate target cell does not need to update the security key information, the MN can omit the step of sending the SN modification request message to the source SN, that is, omit the step of sending the security key information, and directly enter the terminal Steps for sending RRC reconfiguration messages; in addition, MN can also send an RRC reconfiguration message to the terminal after sending an SN modification request message to the source SN, instead of waiting for the source SN to return a message indicating that the security key information has been received Send after confirming the message to save time for SN change.

此时，当终端根据所接收到的SN change变更条件，判断得到候选目标小区满足该SN change变更条件时，将执行SN change操作，并向MN发送携带有指示SN配置成功的指示信息和变更后的目标SN的标识信息的RRC消息，当然该目标SN即为源SN，即为SN内部变更。At this time, when the terminal determines that the candidate target cell meets the SN change condition according to the received SN change condition, it will execute the SN change operation and send to the MN the indication information indicating that the SN configuration is successful. The RRC message of the identification information of the target SN, of course, the target SN is the source SN, that is, the internal change of the SN.

这样，本实施例通过源SN配置得到SN change触发条件，使得SN change的执行能够很好的适应SN本身的RRM策略。In this way, in this embodiment, the SN change trigger condition is obtained through the source SN configuration, so that the execution of the SN change can well adapt to the RRM policy of the SN itself.
