具体实施方式
首先指出的是，终端的能力可以分为无线能力和核心网能力两种。对于无线能力，终端可根据网络的请求上报终端的无线能力。对于核心网能力，终端可在注册时上报终端的网络能力。
终端可以支持多个频带(Band)和频率(frequency)。随着CA(Carrier Aggregation载波聚合)和DC(Dual Connectivity双连接)等技术的引入，需要排列组合各种可能的频带组合，而且各个终端厂家支持的频带组合可能还各不相同，造成无线能力特别庞大。另外，随着网络的演进，越来越多的特性被引入网络，不同的特性往往需要不同的无线能力和网络能力。对于相关的网络特性，终端需要将是否支持的信息告知网络。
一般来说，每个出厂的终端都有设备标识信息，比如国际移动设备识别码(International Mobile Equipment Identity，IMEI)。IMEI中可包含类型分配码(Type Allocation Code，TAC)，该TAC通常由8位数字组成(早期是6位)，是区分终端品牌和型号的编码，该TAC由GSMA及其授权机构分配。其中该TAC的前两位又称为分配机构标识(Reporting Body Identifier)，是授权IMEI分配机构的代码，如01为美国CTIA，35为英国BABT，86为中国TAF。通过TAC，可以唯一标识同一终端型号。而同一终端型号的终端能力往往是相同的。
IMEI中还可以包含软件版本号(Software Version Number，SVN)，该SVN可以区分同型号终端出厂时使用的不同软件版本。SVN仅在部分品牌的部分机型中存在。不同SVN可以对应不同的终端能力。
为了减少终端能力上报带来的开销，可为终端设置能够指示终端能力的 标识信息。一种终端能力信令优化的方法是终端仅向网络上报指示终端能力的标识信息。网络通过指示终端能力的标识信息可映射得到终端能力。终端能力标识信息可以是指示终端能力的能力标识信息。
由于实际需求的变化，终端能力可能会发生更新。更新场景可如下所述：
场景一：出厂时，终端很多能力可能处于关闭状态，后续软件升级，会打开某些能力，比如VoLTE能力，某些band能力等。此时会批量升级终端能力。VoLTE等特性的能力的规模(size)是可控的，但band的能力变更会导致CA或DC的能力变更，变更的能力的规模可能很大。
对于场景一，目前终端的TVN在出厂后就不会变更。后续软件升级会打开某些能力，终端厂家可能会变更SVN，也可能不会变更SVN。因此网络无法直接从终端的SVN获知终端的能力是否发生了变更。对于网络分配能力标识信息的场景，即使获知了变更，网络也需要终端完整的无线能力，去查询确认是否已存在该无线能力对应的能力标识信息，是否需要分配新的能力。这对于后台实现是一个巨大的工作量。
场景二：对于同一型号的不同终端，一个终端是数据优先(data centric)，接入4G网络时，可打开5G网络能力；另一个终端是语音优先(voice centric)，当确认5G网络不支持语音时，可能关闭5G网络能力。关闭5G网络能力后，终端要向网络发起位置更新，指示新的网络能力。
本公开实施例中，终端能力的标识信息(可简称为终端能力标识信息)可以用于识别终端能力。终端能力标识信息与终端能力信息之间存在映射的关系，通过终端能力标识信息可以映射出终端能力。终端能力标识信息可以映射出一组终端能力或完整的终端能力。由于终端能力标识信息大小比终端能力小，可以达到节省能力信令优化的效果。

可选地，该终端能力标识信息的操作信息可以包括以下至少一项：关闭的能力标识信息、失效的能力标识信息、删除的能力标识信息、挂起的能力标识信息、新增的能力标识信息和恢复的能力标识信息。
需要说明的是，同一终端可能具有一个或多个能力标识信息。一种实施场景下，只有部分能力标识信息对应的能力关闭时，该终端能力标识信息的操作信息可以用于指示关闭的能力标识信息。比如终端接入4G网络后关闭5G网络的能力，可以通知网络5G网络能力的能力标识信息。不难理解，在多个能力标识信息的场景下，该终端能力标识信息的操作信息具有其特有的优势。
可选地，终端位置变更信息可以包括以下至少一项：终端位置是否变更的指示信息、第一终端的标识(如终端的设备标识(如IMEI标识))和第二终端的标识(如终端的设备标识(如IMEI标识))。一种实施方式中，当执行主体终端为卡时，卡从第一终端转移到第二终端。通过第一终端的标识和第二终端的标识不同，可以协助第一目标端确认终端位置变更。
可选地，该终端能力变更信息可以包括以下至少一项：能力变更指示信息、能力变更类型信息、能力变量信息、第一能力标识信息和第二能力标识信息。不难理解，通过该终端能力变更信息，可以指示终端能力是否发生变更和/或指示变更前和变更后能力的差异。一种实施方式中，能力变更指示信息指示能力是否发生变更。
具体地，第一能力标识信息为更新前终端能力映射的能力标识信息，第二能力标识信息为更新后终端能力映射的能力标识信息。一种实施方式中。通过第一能力标识信息和/或第二能力标识信息可表示终端能力变更信息。不难理解，该方式可适用于终端厂家分配能力标识信息的方式。

进一步地，该能力变量信息可以包括以下至少一项：能力变量的能力标识信息、发生变更能力的能力信息、新增能力的能力信息、关闭能力的能力信息、变更前能力的能力标识信息、变更后能力的能力标识信息、新增能力的能力标识信息和关闭能力的能力标识信息。进一步地，能力信息可以包括至少以下一项：能力指示辅助信息、能力上下文。不难理解，能力变量信息的方式可适用于网络分配能力标识的方式。通过能力变量信息，不需要终端发送完整的终端能力，节省了信令，又能支持网络推导出更新后的能力并为更新后的能力分配能力标识信息。
一种实施方式下，通过第一能力标识信息和能力变量信息，可以指示变更的终端能力。不难理解，可以协助第一目标端推导出更新后的终端能力。
一种实施方式下，通过第一能力标识信息和能力变量的标识信息，可以推导得到变更后的终端能力。比如终端关闭了某个无线接入类型(Radio Access Type，RAT)能力，通过一个大能力标识(如第一能力标识信息)和一个关闭的小能力标识(如能力变量标识信息)，可以指示更新后的终端能力；或者终端打开了一个RAT能力，通过一个大能力标识和一个新增的小能力标识，可以指示更新后的终端能力。
一种实施方式下，通过第一能力标识信息和第二能力标识信息，可以指示终端能力发生变更。不难理解，而第一目标端接收到第二能力标识信息后，可以将终端能力标识信息更新为第二能力标识信息，也可以根据第二能力标识信息，获取变更后的终端能力。或者第一目标端可以根据第一能力标识信息和第二能力标识信息，获取某个能力变量信息。
一种实施方式下，通过终端能力标识信息的指示信息和第二能力标识信息，可以将终端能力标识信息更新为第二能力标识信息，也可以协助第一目标端根据第二能力标识信息，获取更新后的终端能力。
一种实施方式中，比如终端的能力标识信息由2、3、4和5这四个标识构成，分别对应2G网络能力、3G网络能力、4G网络能力和5G网络能力，则当决定关闭5G网络能力时，终端可以通知网络能力标识5对应的能力关闭。网络可以在相应终端上下文中删除能力标识5。
一种实施方式中，比如终端的能力标识信息由基本能力标识1，以及额外能力变量的能力标识A、B和C构成，其中终端UE1的能力标识为1和A时，表示UE1支持1和A映射的能力，终端UE2的能力标识为1和B时，表示UE1支持1和B映射的能力，以此类比。后续当UE1关闭A映射的能力时，UE1可以通知网络其关闭了A映射的能力，而网络可以删除能力标识A，保留能力标识1，以表示UE1仅剩下能力标识1映射的基本能力。若后续UE1又打开A映射的能力，则可以通知网络，而网络可以新增或恢复能力标识A。
另一种实施方式中，比如终端的能力标识信息由终端类别全能力标识1，以及关闭能力变量标识A，B，C构成，终端类别全能力标识可以包括终端的型号和/或软件版本。其中终端UE3的能力标识为1和A时，表示UE3支持标识1映射的能力减去A映射的能力。后续当UE3打开A映射的能力，UE3可以通知网络删除标识A。当UE3又关闭A映射的能力时，可以通知网络新增能力标识A。
可以理解的是，通过不同的能力标识分配方式，即单标识或多标识，网络分配或终端厂家分配，可以保证在终端能力更新后，既可以节省能力上报信令，又能够保证终端能力在终端和网络侧保持同步。
可以理解的是，本公开实施例中，通过终端能力第一相关操作，可以在终端能力更新时，达到优化终端能力上报的效果，节省能力上报信令，又可以满足同一终端在不同条件下对应不同终端能力需求。
