Description
本申请要求于2021年4月21日提交中国国家知识产权局、申请号202110431803.2、申请名称为“一种信息配置方法以及相关设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
本申请实施例涉及通信领域，尤其涉及一种信息配置方法以及相关设备。
报文序列号信息属于基站与终端之间的无线承载(data radio bearer，DRB)的相关配置，该报文序列号信息包括分组数据汇聚协议(packet data convergence protocol，PDCP)的报文序列号信息，以及无线链路控制协议(radio link control，RLC)的报文序列号信息。在终端与基站进行通信的过程中，需要保证终端侧配置的报文序列号信息与小区侧配置的报文序列号信息一致，否则可能会导致通信业务的异常。
在现有的技术当中，如果终端需要进行小区间的切换，基站会向终端发送终端所要切换到的小区配置的报文序列号信息，终端接收到上述报文序列号信息之后，需要将上述报文序列号信息配置到本地，从而保证与小区配置的报文序列号信息一致，并在完成报文序列号信息的配置之后向基站发送切换完成消息，若终端未能完成上述报文序列号信息的配置，则终端不会向基站发送上述切换完成消息，即终端重配置报文序列号信息失败，随后终端会向基站发起重建，从而继续开展通信业务。
然而，终端可能会重建到任意小区，因此终端侧配置的报文序列号信息与小区侧配置的报文序列号信息可能会不一致，导致后续通信业务的异常。
发明内容
本申请实施例提供了一种信息配置方法以及相关设备，用于使终端重配置失败之后，终端侧配置的报文序列号信息与小区侧配置的报文序列号信息保持一致。
本申请实施例第一方面提供了一种信息配置方法：
在终端与基站的通信过程中，终端配置的报文序列号信息需要和终端所接入的小区的报文序列号信息一致，因此终端可能需要对报文序列号信息进行重新配置，然而终端重配置报文序列号信息可能会失败，终端重配置报文序列号信息失败之后，会向基站发起重建。如果基站确定终端重配置报文序列号信息失败，并且接收到来自终端的重建请求消息，该重建请求消息为终端向基站的第一小区发送，该重建请求消息用于表示终端请求重建到第一小区，基站接收到来自终端的重建请求消息之后，为了保证终端配置的报文序列号信息与第一小区配置的报文序列号信息一致，会向终端发送第一报文序列号信息，该第一报文序列号信息和上述第一小区配置的第一报文序列号信息一致，终端接收到该第一报文序列号信息之后，可以在本地配置该第一报文序列号信息，在终端配置上述第一报文序列号信息之后，基站可以接收到来自终端的第一切换完成消息或者第一重配完成消息，该第一切换完成消息或者第一重配完成消息用于表示终端已经成功配置第一报文序列号信息。
本申请实施例中，终端重配置失败并向第一小区发起重建之后，基站会向终端发送第一报文序列号信息，使得终端配置上述第一报文序列号信息，从而保证终端配置的第一报文序列号信息与第一小区配置的报文序列号信息一致，确保通信业务的正常开展。
在一种可能的实现方式中，终端重配置报文序列号信息失败具体可以是，基站向终端发送第二报文序列号信息，该第二报文序列号信息用于终端在本地配置第二报文序列号信息，该第二报文序列号信息与第二小区配置的报文序列号信息一致，该第二报文序列号信息用于终端与第二小区建立连接，基站包括上述第二小区。终端在将上述第二报文序列号信息配置完成之后，会向基站发送第二切换完成消息或者第二重配完成消息，若基站在预设的时长内没接收到来自终端的第二切换完成消息或者第二重配完成消息，则基站可以确定终端重配置报文序列号信息失败。
在一种可能的实现方式中，基站可以通过切换命令或者重配消息向终端发送第一报文序列号信息。
本申请实施例中，限定了基站向终端发送第一报文序列号信息的形式，提高了方案的可实现性。
在一种可能的实现方式中，在基站向终端发送第一报文序列号信息之后，如果在预设的时长内基站未接收到来自终端的第一切换完成消息或者第一重配完成消息，则基站会继续向终端发送第一报文序列号信息，直至接收到来自终端的第一切换完成消息或者第一重配完成消息。
本申请实施例中，基站可以多次向终端发送第一报文序列号信息，从而确保终端可以成功将第一报文序列号信息配置完成。
在一种可能的实现方式中，第一报文序列号信息与第二报文序列号信息包括分组数据汇聚协议(packet data convergence protocol，PDCP)的报文序列号信息以及无线链路控制协议(radio link control，RLC)的报文序列号信息。
本申请实施例第二方面提供了一种基站，该基站包括输入输出设备以及处理器，其中，处理器用于执行上述第一方面中的方法。
本申请实施例第三方面提供了一种基站，该基站具有实现上述第一方面中基站的功能。该功能可以通过硬件实现，也可以通过硬件执行相应的软件实现。该硬件或软件包括一个或多个与上述功能对应的模块。
本申请实施例第四方面提供了一种计算机可读存储介质，该计算机可读存储介质中保有程序，当计算机运行程序时，执行上述第一方面中的方法。

下面结合附图，对本申请的实施例进行描述，显然，所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。本领域普通技术人员可知，随着技术发展和新场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
本申请实施例提供了一种信息配置方法，用于确定终端按照基站下发的报文序列号信息配置完成。
本申请实施例可以应用于基站与终端之间的通信场景，请参阅图1，的覆盖范围可以划分为不同的小区，其中不同的小区可能会配置不同的报文序列号信息，示例性的，如图1中所示，小区1配置报文序列号信息1，小区2配置报文序列号信息2，小区3配置报文序列号信息3，小区4配置报文序列号信息4，小区5配置报文序列号信息5，小区6配置报文序列号信息6，当终端接入小区6时，终端本地需要配置报文序列号信息6，如果终端本地配置的报文序列号信息与小区配置的报文序列号信息不一致，可能会导致通信业务的异常，因此，当终端需要进行小区间的切换时，例如，当终端从小区6切换至小区5时，需要保证终端本地配置的报文序列号信息与小区5配置的报文序列号信息一致。
请参阅图2，下面对本申请实施例中信息配置方法的一个流程进行描述：
201、基站确定终端重配置报文序列号信息失败；
终端在一些场景下需要对报文序列号信息进行重配置，该报文序列号信息属于无线承载(data radio bearer，DRB)的相关配置，若终端重配置报文序列号信息失败，基站可以确定终端重配置报文序列号信息失败。
202、基站接收来自终端的重建请求消息；
终端重配置失败后，会向基站发送重建请求消息，该重建请求消息用于表示终端请求重建到第一小区。
203、基站向终端发送重建消息；
基站接收到来自终端的重建请求消息之后，向终端发送重建消息。
204、终端向基站发送重建完成消息；
终端接收到来自基站的重建消息之后，向基站发送重建完成消息。
205、基站向终端发送第一报文序列号信息；
由于终端请求重建到第一小区，而第一小区配置第一报文序列号信息，因此基站向终端发送第一报文序列号信息，终端接收到该第一报文序列号信息之后在本地配置该第一报文序列号信息，具体的，基站可以通过切换命令或重配消息向终端发送第一报文序列号信息。
206、基站接收来自终端的第一切换完成消息或第一重配完成消息。
终端接收到来自基站的第一报文序列号信息之后，将第一报文序列号信息配置到本地，配置完成之后，终端向基站发送第一切换完成消息或第一重配完成消息，该第一切换完成消息或第一重配完成消息用于表示终端已经完成第一报文序列号信息的配置，需要说明的是，在步骤205中，若基站通过切换命令向终端发送第一报文序列号信息，则终端向基站发送第一切换完成消息，若基站通过重配消息向终端发送第一报文序列号信息，则终端向基站发送第一重配完成消息。
本申请实施例中，终端由于重配置报文序列号信息失败而发起到第一小区的重建之后，基站向终端发送第一小区所配置的第一报文序列号信息，使得终端侧的报文序列号信息与小区侧的报文序列号信息一致，从而保证通信业务的正常开展。
在另一种可能的实现方式中，如果基站向终端发送第一报文序列号信息之后，终端没有向基站发送第一切换完成消息，基站也可以继续向终端发送第一报文序列号信息，请参阅图3，下面进行详细描述：
本实施例中，步骤301至步骤305与上述图2所示实施例中步骤201至步骤205类似，此处不再赘述。
306、基站确定在预设时长内未接收到来自终端的第一切换完成消息或第一重配完成消息；
基站向终端发送第一报文序列号信息之后，确定在预设的时长内未接收到来自终端的第一切换完成消息或第一重配完成消息。
307、基站向终端发送第一报文序列号信息；
基站确定在预设的时长内未接收到来自终端的第一切换完成消息，为了确保终端成功在本地配置第一报文序列号信息，基站继续向终端发送第一报文序列号信息。
308、基站接收来自终端的第一切换完成消息或第一重配完成消息。
终端接收到来自基站的第一报文序列号信息之后，将第一报文序列号信息配置到本地，配置完成之后，终端向基站发送第一切换完成消息或第一重配完成消息，该第一切换完成消息或第一重配完成消息用于表示终端已经完成第一报文序列号信息的配置。
需要说明的是，上述步骤306以及步骤307可以重复执行多次，直至基站接收到来自终端的第一切换完成消息或第一重配完成消息。
本申请实施例中，基站在未接收到来自终端的第一切换完成消息或第一重配完成消息的情况下，可以继续向终端发送第一报文序列号信息，从而提高终端成功配置第一报文序列号信息的概率。
请参阅图4，下面结合终端重配置报文序列号信息失败的具体情形，对本申请实施中信息配置方法的另一流程进行描述：
401、基站向终端发送切换命令；
终端需要进行对报文序列号信息进行重配置时，例如，终端需要进行小区间的切换时，基站会向终端发送切换命令，该切换命令中会携带第二报文序列号信息，示例性的，终端当前接入了小区6，但是小区5向终端提供的信号强度比小区6向终端提供的信号强度大，因此终端需要切换至小区5，小区5即为第二小区，基站会向终端发送切换命令，终端接收到切换命令后，会将切换命令中携带的第二报文序列号信息配置到本地，该第二报文序列号信息用于终端切换至第二小区，第二报文序列号信息与第二小区配置的报文序列号信息一致。
402、基站确定在预设时长内未接收到来自终端的第二切换完成消息；
基站向终端发送第二报文序列号信息之后，若终端成功将第二报文序列号信息配置到本地，则终端会向基站发送第二切换完成消息，该第二切换完成消息用于表示终端已经完成第二报文序列号信息的配置，但是如果终端配置第二报文序列号信息失败，则终端不会向基站发送第二切换完成消息，或者，终端将第二报文序列号信息配置完成之后，也可能向基站发送第二切换完成消息失败，因此，若基站确定在预设的时长内未接收到来自终端的第二切换完成消息，则基站无法确定终端是否已经将第二报文序列号信息配置完成，即终端重配置报文序列号信息失败。
403、基站接收来自终端的重建请求消息；
若终端未向基站发送第二切换完成消息，则终端会向基站的第一小区发送重建请求消息，该重建请求消息用于表示终端请求重建到第一小区，需要说明的是，第一小区与上述第二小区可以是同一个小区，也可以是不同的小区，具体此处不做限定。
404、基站向终端发送重建消息；
基站接收到来自终端的重建请求消息之后，向终端发送重建消息。
405、终端向基站发送重建完成消息；
终端接收到来自基站的重建消息之后，向基站发送重建完成消息。
406、基站向终端发送第一报文序列号信息；
由于终端请求重建到第一小区，而第一小区配置第一报文序列号信息，因此基站向终端发送第一报文序列号信息，终端接收到该第一报文序列号信息之后在本地配置该第一报文序列号信息，需要说明的是，第一报文序列号信息与第二报文序列号信息可以相同，或者也可以不同，具体此处不做限定。具体的，基站可以通过切换命令或者重配消息向终端发送第一报文序列号信息。
407、基站接收来自终端的第一切换完成消息或第一重配完成消息。
终端接收到来自基站的第一报文序列号信息之后，将第一报文序列号信息配置到本地，配置完成之后，终端向基站发送第一切换完成消息或第一重配完成消息，该第一切换完成消息或第一重配完成消息用于表示终端已经完成将第一报文序列号信息的配置。在步骤406中，若基站通过切换命令向终端发送第一报文序列号信息，则终端向基站发送第一切换完成消息，若基站通过重配消息向终端发送第一报文序列号信息，则终端向基站发送第一重配完成消息。
本申请实施例中，终端由于重配置报文序列号信息失败而发起到第一小区的重建之后，基站向终端发送第一小区所配置的第一报文序列号信息，使得终端侧的报文序列号信息与小区侧的报文序列号信息一致，从而保证通信业务的正常开展。
在另一种可能的实现方式中，如果基站向终端发送第一报文序列号信息之后，终端没有向基站发送第一切换完成消息或第一重配完成消息，基站也可以继续向终端发送第一报文序列号信息，请参阅图5，下面进行详细描述：
本实施例中，步骤501至步骤506与上述图5所示实施例中步骤401至步骤406类似，此处不再赘述。
507、基站确定在预设时长内未接收到来自终端的第一切换完成消息或第一重配完成消息；
基站向终端发送第一报文序列号信息之后，确定在预设的时长内未接收到来自终端的第一切换完成消息或第一重配完成消息。
508、基站向终端发送第一报文序列号信息；
基站确定在预设的时长内未接收到来自终端的第一切换完成消息或第一重配完成消息，为了确保终端成功在本地配置第一报文序列号信息，基站继续向终端发送第一报文序列号信息。
509、基站接收来自终端的第一切换完成消息或第一重配完成消息。
终端接收到来自基站的第一报文序列号信息之后，将第一报文序列号信息配置到本地，配置完成之后，终端向基站发送第一切换完成消息或第一重配完成消息，该第一切换完成消息或第一重配完成消息用于表示终端已经完成将第一报文序列号信息的配置。
需要说明的是，上述步骤507以及步骤508可以重复执行多次，直至基站接收到来自终端的第一切换完成消息或第一重配完成消息。
本申请实施例中，基站在未接收到来自终端的第一切换完成消息或第一重配完成消息的情况下，可以继续向终端发送第一报文序列号信息，从而提高终端成功配置第一报文序列号信息的概率。
在另一种可能的实现方式中，基站也可以通过重配消息向终端发送第二报文序列号信息，请参阅图6，下面进行详细描述：
601、基站向终端发送重配消息；
在另一种场景下，终端不需要进行小区的切换，但是需要更新终端与基站之间的DRB相关的配置，其中就包括了报文序列号信息，基站可以通过重配消息向终端发送第二报文序列号信息，该第二报文序列号信息用于终端与第二小区建立连接，第二报文序列号信息与第二小区配置的报文序列号信息一致。
602、基站确定在预设时长内未接收到来自终端的第二重配完成消息；
基站向终端发送第二报文序列号信息之后，若终端成功将第二报文序列号信息配置到本地，则终端会向基站发送第二重配完成消息，该第二重配完成消息用于表示终端已经完成第二报文序列号信息的配置，但是如果终端将第二报文序列号信息配置失败，则终端不会向基站发送第二重配完成消息，或者，终端将第二报文序列号信息配置完成之后，也可 能向基站发送第二重配完成消息失败，因此，若基站确定在预设的时长内未接收到来自终端的第二重配完成消息，则基站无法确定终端是否已经将第二报文序列号信息配置完成，即重配置报文序列号信息失败。
603、基站接收来自终端的重建请求消息；
若终端未向基站发送第二切换完成消息，则终端会向基站的第一小区发送重建请求消息，该重建请求消息用于表示终端请求重建到第一小区，需要说明的是，第一小区与上述第二小区可以是同一个小区，也可以是不同的小区，具体此处不做限定。

607、基站接收来自终端的第一切换完成消息或第一重配完成消息。
终端接收到来自基站的第一报文序列号信息之后，将第一报文序列号信息配置到本地，配置完成之后，终端向基站发送第一切换完成消息或第一重配完成消息，该第一重配完成消息或第一切换完成消息用于表示终端已经完成将第一报文序列号信息的配置。在步骤606中，若基站通过切换命令向终端发送第一报文序列号信息，则终端向基站发送第一切换完成消息，若基站通过重配消息向终端发送第一报文序列号信息，则终端向基站发送第一重配完成消息。
