具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开实施例范围的情况下，第一SIM卡也可以被称为第二SIM卡，类似地，第二SIM卡也可以被称为第一SIM卡。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
出于简洁和便于理解的目的，本文在表征大小关系时，所使用的术语为“大于”或“小于”、“高于”或“低于”。但对于本领域技术人员来说，可以理解：术语“大于”也涵盖了“大于等于”的含义，“小于”也涵盖了“小于等于”的含义；术语“高于”涵盖了“高于等于”的含义，“低于”也涵盖了“低于等于”的含义。
图1是根据本公开的实施例示出的一种能力指示方法的示意流程图。本实施例所示的能力指示方法可以由基站执行，所述基站可以与终端、核心网等通信装置通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置，所述基站包括但不限于4G、5G、6G等通信系统中的基站。
在一个实施例中，在所述终端可以设置有多个SIM卡，可以是传统的SIM卡，也可以是eSIM卡，也即嵌入式SIM卡。
以下主要在多个SIM卡包括第一SIM卡和第二SIM卡的情况下，对本公开的技术方案进行示例性说明。其中，第一SIM卡和第二SIM卡并非特指某个SIM卡，而是用于表示多个SIM卡中任意两个不同的SIM卡。第一SIM卡和第二SIM卡可以 属于相同的运营商，也可以属于不同的运营商，具体可以根据需要选择。
如图1所示，所述能力确定方法可以包括以下步骤：
在步骤S101中，向核心网发送第一能力信息，其中，所述第一能力信息用于指示所述基站对终端进行多SIM卡连接切换的支持能力。
在一个实施例中，所述终端中设置有多个SIM卡，所述多个SIM卡至少包括第一SIM卡和第二SIM卡，所述多SIM卡连接切换包括在通过第一SIM卡进行通信操作时，切换到第二SIM卡进行通信操作(在这种情况下第一SIM卡进行的通信操作可以中断)。需要说明的是，多SIM卡连接切换并不限于上述情况，例如还可以包括通过第一SIM卡进行通信操作时，启动第二SIM卡同时进行通信操作(在这种情况下第一SIM卡进行的通信操作可以不中断)。以下主要针对多SIM卡连接切换包括通过第一SIM卡进行通信操作时，切换到第二SIM卡进行通信操作的情况，对本公开的技术方案进行示例性说明。
针对这种情况，需要基站、核心网等网络侧设备针对终端做出适当的操作和配置。以网络侧设备包括基站为例，例如终端通过第一SIM卡与第一基站通信时，需要通过第二SIM卡与第二基站通信，例如接收第二基站发送的系统信息，那么就第一基站与第一SIM卡之间的通信操作就需要中断一段时间，在通过第二SIM卡与第一基站通信完毕后，第一基站再恢复与第一SIM卡之间的通信操作。
但是，并非所有网络侧设备都支持第一SIM卡通信操作中断后再恢复。例如，有的基站能够针对终端进行多SIM连接切换的情况做出适当的操作和配置，也即支持多SIM卡连接切换，有的基站则不能，也即不支持多SIM卡连接切换。并且对于支持多SIM卡连接切换的网络侧设备，对于多SIM卡连接切换的具体支持情况也可能有所不同，例如基站可以支持第一SIM卡离开连接态时的多SIM卡连接切换，或者支持第一SIM卡保持在连接态时的多SIM卡连接切换。
考虑到上述技术问题，本公开的实施例中，基站可以根据自身对于多SIM卡连接切换的支持能力生成第一能力信息，进而将第一能力信息发送给核心网，核心网在接收到第一能力信息后，就可以根据第一能力信息确定基站对于终端进行多SIM卡连接切换的支持能力，例如是否支持多SIM卡连接切换，例如在支持多SIM卡连接切换的情况下，具体支持何种条件下的多SIM卡连接切换。
由于核心网可以接收到至少一个基站上报的第一能力信息，也就可以确定至少 一个基站对于多SIM卡连接切换的支持能力，进而后续可以根据需要将基站对于多SIM卡连接切换的支持能力告知终端，例如终端可以接收到所述核心网发送的信息，但是暂时不能接收到所述基站发送的信息，例如核心网确定终端将要进入目标基站的信号覆盖区域，那么可以将目标基站对于多SIM卡连接切换的支持能力告知终端，以便终端据此确定是否接入目标基站、是否向目标基站上报进行多SIM卡的信息、是否能够向目标基站请求进行多SIM卡连接切换的间隙等。
在一个实施例中，核心网可以将基站对于多SIM卡连接切换的第一能力信息发送给终端，例如终端可以从核心网接收到多个基站对于多SIM卡连接切换的能力信息，终端可以确定自身对于多SIM卡连接切换的支持能力，进而确定对于多SIM卡连接切换的支持能力与终端对于多SIM卡连接切换的支持能力相匹配的基站。
例如终端自身支持在第一SIM卡保持在连接态的情况下，进行多SIM卡连接切换，在接收到的多个基站对于多SIM卡连接切换的能力信息中，可以确定基站X支持在第一SIM卡保持在连接态的情况下，进行多SIM卡连接切换，基站Y则仅支持在第一SIM卡离开连接态的情况下，进行多SIM卡连接切换，那么可以确定基站X对于多SIM卡连接切换的支持能力与终端自身对于多SIM卡连接切换的支持能力是匹配的，而基站Y对于多SIM卡连接切换的支持能力与终端自身对于多SIM卡连接切换的支持能力是不匹配的。
进而终端对于基站X和基站Y，可以优先选择基站X接入，例如可以优先选择驻留在基站X对应的小区，例如可以优先选择基站X对应的小区进行小区重选。据此，可以确保终端在接入基站X后，在进行多SIM卡连接切换时，将多SIM卡连接切换的信息上报至基站X后，基站X有能力对终端进行多SIM卡连接切换做出合理的配置。
其中，进行多SIM卡连接切换的信息包括但不限于以下至少之一：通过第二SIM卡进行通信操作的类型、第二SIM卡的标识、通过第二SIM卡进行通信操作的时长。多SIM卡连接切换对应的配置，包括终端进行多SIM卡连接切换的间隙gap相关信息，例如间隙起始位置、间隙结束位置、间隙持续时长、间隙类型(周期、非周期)等。
在一个实施例中，所述第一能力信息还用于指示与所述基站连接的其他基站对终端进行多SIM卡连接切换的支持能力。
基站之间可以通过建立接口形成通信连接，例如基站A和基站B之间可以建立接口，例如X2接口、Xn接口，例如基站B可以是基站A的邻基站。基站A和基站B之间可以通过接口通信，例如基站B可以将自身对于多以SIM卡连接切换的支持能力告知基站A，进而基站A可以在第一能力信息中携带基站A对于多SIM卡连接切换的支持能力和基站B对于多SIM卡连接切换的支持能力发送至核心网。
据此，在核心网与一个基站之间存在通信连接情况下，可以获取到至少一个基站对于多SIM卡连接切换的支持能力，有利于提高基站与核心网之间通信资源的使用效率。
图2是根据本公开的实施例示出的另一种能力指示方法的示意流程图。如图2所示，所述向核心网发送第一能力信息包括：
在步骤S201中，在与所述核心网建立接口的过程中，向所述核心网发送所述第一能力信息。
在一个实施例中，基站可以在与核心网建立接口的过程中，将第一能力信息发送至核心网。据此，使得核心网尽快确定基站对于多SIM卡连接切换的支持能力。
在一个实施例中，在所述基站包括演进的通用陆基无线接入网E-UTRAN(evolved universal terrestrial radio access network)基站的情况下，所述第一能力信息能携带S1接口建立请求S1 SETUP REQUEST信令中。
Figure PCTCN2021118884-appb-000001
表1
例如S1接口建立请求信令可以如上述表1所示，其中携带有消息类型Message Type、全球基站标识Global eNB ID等信息(表中仅示出了该信令携带的部分信息)，还可以携带离开能力Leaving Capability，也即第一能力信息。可以理解的是，表1中的每一个元素都是独立存在的，这些元素被示例性的列在同一张表格中，但是并不代表表格中的所有元素必须根据表格中所示的同时存在。其中每一个元素的值，是不依赖于表1中任何其他元素值。因此本领域内技术人员可以理解，该表1中的每一个元素的取值都是一个独立的实施例。
在一个实施例中，在所述基站包括新空口NR(New Radio)基站的情况下，所述第一能力信息携带在NG接口建立请求NG SETUP REQUEST信令中。
Figure PCTCN2021118884-appb-000002
表2
例如NG接口建立请求信令可以如上述表2所示，其中携带有消息类型Message Type、全球无线接入点标识Global RAN Node ID等信息(表中仅示出了该信令携带的部分信息)，还可以携带离开能力Leaving Capability，也即第一能力信息。可以理解的是，表2中的每一个元素都是独立存在的，这些元素被示例性的列在同一张表格中，但是并不代表表格中的所有元素必须根据表格中所示的同时存在。其中每一个元素的值，是不依赖于表2中任何其他元素值。因此本领域内技术人员可以理解，该表2中的每一个元素的取值都是一个独立的实施例。
图3是根据本公开的实施例示出的又一种能力指示方法的示意流程图。如图3所示，所述向核心网发送第一能力信息包括：
在步骤S301中，在与所述核心网建立接口后，向所述核心网发送所述第一能力信息。
在一个实施例中，基站可以在与核心网建立接口的过程后，将第一能力信息发送至核心网。据此，可以减少建立接口过程中的信令所携带的信息，从而减少核心网在建立接口过程中所需解析的信息量，有利于加快建立接口的速度。
在一个实施例中，在所述基站包括E-UTRAN基站的情况下，所述第一能力信息携带在基站配置更新ENB CONFIGURATION UPDATE信令中。基站在更新配置时，可以向核心网发送基站配置更新信令，并在信令中携带第一能力信息发送至核心网。当然，除了基站配置更新信令，基站也可以根据需要通过其他信令携带第一能力信息发送至核心网。
在一个实施例中，在所述基站包括NR基站的情况下，所述第一能力信息携带在无线接入网配置更新RAN CONFIGURATION UPDATE信令中。基站在更新无线接入网配置时，可以向核心网发送无线接入网配置更新信令，并在信令中携带第一能力信息发送至核心网。当然，除了无线接入网配置更新信令，基站也可以根据需要通过其他信令携带第一能力信息发送至核心网。
图4是根据本公开的实施例示出的又一种能力指示方法的示意流程图。如图4所示，所述方法还包括：
在步骤S401中，接收所述核心网发送的第二能力信息，其中，所述第二能力信息用于指示所述核心网对终端进行多SIM卡连接切换的支持能力。
在一个实施例中，核心网可以根据自身对于多SIM卡连接切换的支持能力生成第二能力信息，进而将第二能力信息发送给基站，基站在接收到第二能力信息后，就可以根据第二能力信息确定核心网对于终端进行多SIM卡连接切换的支持能力，例如是否支持多SIM卡连接切换，例如在支持多SIM卡连接切换的情况下，具体支持何种条件下的多SIM卡连接切换。
在一个实施例中，所述方法还包括：将所述第二能力信息发送至终端。需要说明的是，基站也可以将第一能力发送至终端。
基站在确定核心网对于多SIM卡连接切换的支持能力后，后续可以根据需要将基站对于多SIM卡连接切换的支持能力告知终端，以便终端据此确定是否接入核心网，例如注册、附着到核心网。
在一个实施例中，基站可以将多个核心网对于多SIM卡连接切换的第二能力信息发送给终端，终端可以确定自身对于多SIM卡连接切换的支持能力，进而确定对于多SIM卡连接切换的支持能力与终端对于多SIM卡连接切换的支持能力相匹配的核心网。
例如终端自身支持在第一SIM卡保持在连接态的情况下，进行多SIM卡连接切换，在接收到的多个核心网对于多SIM卡连接切换的能力信息中，可以确定核心网X支持在第一SIM卡保持在连接态的情况下，进行多SIM卡连接切换，核心网Y则仅支持在第一SIM卡离开连接态的情况下，进行多SIM卡连接切换，那么可以确定核心网X对于多SIM卡连接切换的支持能力与终端自身对于多SIM卡连接切换的支持能力是匹配的。
进而终端对于核心网X和核心网Y，可以优先选择核心网X接入，例如可以优先选择核心网X进行注册或附着。据此，可以确保终端在接入核心网X后，在进行多SIM卡连接切换时，将多SIM卡连接切换的信息上报至核心网X后，核心网X有能力对终端进行多SIM卡连接切换做出合理的配置。
在一个实施例中，所述第二能力信息携带在无线接入控制RRC(Radio Resource Control)信令和/或系统信息SI(System Information)中发送至终端。也即基站可以选择通过广播的方式将第二能力信息携带在SI中发送给终端，也可以选择通过单播的方 式将第二能力信息携带在RRC信令中发送给终端。
图5是根据本公开的实施例示出的又一种能力指示方法的示意流程图。如图5所示，第二能力信息携带在RRC信令中发送至终端，所述将所述第二能力信息发送至终端包括：
在步骤S501中，接收所述终端发送的针对所述第二能力信息的获取请求；
在步骤S502中，将所述第二能力信息发送至所述终端。
在一个实施例中，基站在通过RRC信令携带第二能力信息的情况下，由于是单播方式发送，所以在发送之前与终端之间已经是存在通信连接的，因此可以先确定是否接收到终端发送的获取请求，在接收到获取请求的情况下，可以确定终端需要获取第二能力信息，进而才将第二能力信息携带在RRC信令中发送给终端。据此，可以避免在终端不需要获取第二能力信息的情况下，向终端发送第二能力信息而造成通信资源的浪费。
图6是根据本公开的实施例示出的又一种能力指示方法的示意流程图。如图6所示，所述将所述第二能力信息发送至终端还包括：
在步骤S601中，确定第一条件；
在步骤S602中，根据所述第二能力信息确定第三能力信息，其中，所述第三能力信息用于指示所述核心网对终端在第一条件下进行多SIM卡连接切换的支持能力；
在步骤S603中，将所述第三能力信息发送至所述终端。
在一个实施例中，由于第二能力信息中可以携带多种支持能力，例如可以包括支持多SIM卡连接切换、支持第一SIM卡保持在连接态的情况下进行多SIM卡连接切换、支持第一SIM卡离开连接态的情况下进行多SIM卡连接切换等，但是终端可能并不需要确定对于每种情况多SIM卡连接切换的支持能力，而是只希望确定对于部分情况多SIM卡连接切换的支持能力。
例如终端自身支持在第一条件下进行多SIM卡连接切换，那么终端可以仅需要确定核心网是否也支持在第一条件进行多SIM卡连接切换，而对于在其他条件下的多SIM卡连接切换则不感兴趣。在这种情况下，基站可以确定第一条件，例如第一条件可以由终端上报，例如携带在获取请求中上报，也可以与终端预先约定，由此，基站 可以基于第一条件在第二能力信息中确定第三能力信息，确定的第三能力信息是第二能力信息中针对第一条件下进行多SIM卡连接切换的支持能力，进而将第三能力信息发送至终端。
由于第三能力信息为第二能力信息中的部分能力信息，一般情况下占用的通信资源相对较少，一方面可以满足终端需要，另一方面有利于节约通信资源。
图7是根据本公开的实施例示出的又一种能力指示方法的示意流程图。如图7所示，所述将所述第二能力信息发送至终端包括：
在步骤S701中，确定满足第二条件的目标终端，其中，所述第二条件包括以下至少之一：终端中设置有多个SIM卡、终端支持多SIM卡连接切换；
在步骤S702中，将所述第二能力信息发送至所述目标终端。
在一个实施例中，基站可以选择性地向终端发送第二能力信息，例如可以确定满足第二条件的目标终端，例如目标终端可以是指设置有多个SIM卡的终端，也可以是指支持多SIM卡连接切换的终端，针对这些终端，终端才有可能进行多SIM卡连接切换，进而才有获取第二能力信息的需要，因此可以仅向这些终端发送第二能力信息，有利于避免给不需要获取第二能力信息的终端而造成通信资源的浪费。
图8是根据本公开的实施例示出的一种能力指示方法的示意流程图。本实施例所示的能力指示方法可以由核心网执行，所述核心网可以与终端、基站通信，所述核心网包括但不限于4G、5G、6G等通信系统中的核心网，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。
如图8所示，所述能力指示方法可以包括以下步骤：
在步骤S801中，向基站发送第二能力信息，其中，所述第二能力信息用于指示所述核心网对终端进行多SIM卡连接切换的支持能力。
在一个实施例中，所述终端中设置有多个SIM卡，所述多个SIM卡至少包括第一SIM卡和第二SIM卡，所述多SIM卡连接切换包括在通过第一SIM卡进行通信操作时，切换到第二SIM卡进行通信操作(在这种情况下第一SIM卡进行的通信操作可以中断)。需要说明的是，多SIM卡连接切换并不限于上述情况，例如还可以包括通过第一SIM卡进行通信操作时，启动第二SIM卡同时进行通信操作(在这种情况下第一SIM卡进行的通信操作可以不中断)。以下主要针对多SIM卡连接切换包括通过第一SIM卡进行通信操作时，切换到第二SIM卡进行通信操作的情况，对本公开的技 术方案进行示例性说明。
针对这种情况，需要基站、核心网等网络侧设备针对终端做出适当的操作和配置。但是，并非所有网络侧设备都支持第一SIM卡通信操作中断后再恢复。例如，有的核心网能够针对终端进行多SIM连接切换的情况做出适当的操作和配置，也即支持多SIM卡连接切换，有的核心网则不能，也即不支持多SIM卡连接切换。并且对于支持多SIM卡连接切换的网络侧设备，对于多SIM卡连接切换的具体支持情况也可能有所不同，例如核心网可以支持第一SIM卡离开连接态时的多SIM卡连接切换，或者支持第一SIM卡保持在连接态时的多SIM卡连接切换。
考虑到上述技术问题，本公开的实施例中，核心网可以根据自身对于多SIM卡连接切换的支持能力生成第二能力信息，进而将第二能力信息发送给基站，基站在接收到第二能力信息后，就可以根据第二能力信息确定核心网对于终端进行多SIM卡连接切换的支持能力，例如是否支持多SIM卡连接切换，例如在支持多SIM卡连接切换的情况下，具体支持何种条件下的多SIM卡连接切换，进而后续将第二能力信息发给终端。
由于基站可以接收到至少一个核心网上报的第二能力信息，也就可以确定至少一个核心网对于多SIM卡连接切换的支持能力，进而后续可以根据需要将核心网对于多SIM卡连接切换的支持能力告知终端，例如终端可以接收到所述基站发送的信息，但是暂时不能接收到所述核心网发送的信息，以便终端据此选择合适的核心网进行附着或注册。
在一个实施例中，基站可以将核心网对于多SIM卡连接切换的第二能力信息发送给终端，例如终端可以从基站接收到多个核心网对于多SIM卡连接切换的能力信息，终端可以确定自身对于多SIM卡连接切换的支持能力，进而确定对于多SIM卡连接切换的支持能力与终端对于多SIM卡连接切换的支持能力相匹配的核心网。
例如终端自身支持在第一SIM卡保持在连接态的情况下，进行多SIM卡连接切换，在接收到的多个核心网对于多SIM卡连接切换的能力信息中，可以确定核心网X支持在第一SIM卡保持在连接态的情况下，进行多SIM卡连接切换，核心网Y则仅支持在第一SIM卡离开连接态的情况下，进行多SIM卡连接切换，那么可以确定核心网X对于多SIM卡连接切换的支持能力与终端自身对于多SIM卡连接切换的支持能力是匹配的。
进而终端对于核心网X和核心网Y，可以优先选择核心网X接入，例如可以优先选择向核心网X进行注册或者附着。据此，可以确保终端在接入核心网X后，在进行多SIM卡连接切换时，将多SIM卡连接切换的信息上报至核心网X后，核心网X有能力对终端进行多SIM卡连接切换做出合理的配置。
其中，进行多SIM卡连接切换的信息包括但不限于以下至少之一：通过第二SIM卡进行通信操作的类型、第二SIM卡的标识、通过第二SIM卡进行通信操作的时长。多SIM卡连接切换对应的配置，包括终端进行多SIM卡连接切换的间隙gap相关信息，例如间隙起始位置、间隙结束位置、间隙持续时长、间隙类型(周期、非周期)等。

在步骤S901中，在与所述基站建立接口的过程中，向所述基站发送所述第二能力信息。
在一个实施例中，核心网可以在与基站建立接口的过程中，将第二能力信息发送至基站。据此，使得基站尽快确定核心网对于多SIM卡连接切换的支持能力。

例如NG接口建立响应信令可以如上述表2所示，其中携带有消息类型Message Type、接入移动管理功能名称AMF Name等信息(表中仅示出了该信令携带的部分信息)，还可以携带离开能力Leaving Capability，也即第一能力信息。可以理解的是，表4中的每一个元素都是独立存在的，这些元素被示例性的列在同一张表格中，但是并不代表表格中的所有元素必须根据表格中所示的同时存在。其中每一个元素的值，是不依赖于表4中任何其他元素值。因此本领域内技术人员可以理解，该表4中的每一个元素的取值都是一个独立的实施例。
图10是根据本公开的实施例示出的又一种能力指示方法的示意流程图。如图10所示，所述向基站发送第二能力信息包括：
在步骤S1001中，在与所述基站建立接口后，向所述基站发送所述第二能力信息。
在一个实施例中，核心网可以在与基站建立接口的过程后，将第二能力信息发送至基站。据此，可以减少建立接口过程中的信令所携带的信息，从而减少基站在建立接口过程中所需解析的信息量，有利于加快建立接口的速度。
在一个实施例中，在所述核心网包括E-UTRAN核心网的情况下，所述第二能力信息携带在核心网配置更新MME CONFIGURATION UPDATE信令中。核心网在更新配置时，可以向基站发送核心网配置更新信令，并在信令中携带第二能力信息发送至基站。当然，除了核心网配置更新信令，核心网也可以根据需要通过其他信令携带第二能力信息发送至基站。
在一个实施例中，在所述核心网包括NR核心网的情况下，所述第二能力信息携带在接入移动管理功能配置更新AMF CONFIGURATION UPDATE信令中。核心网在更新接入移动管理功能配置时，可以向基站发送无线接入网配置更新信令，并在信令中携带第二能力信息发送至基站。当然，除了接入移动管理功能更新信令，核心网也可以根据需要通过其他信令携带第二能力信息发送至基站。
图11是根据本公开的实施例示出的又一种能力指示方法的示意流程图。如图 11所示，所述方法还包括：
在步骤S1101中，接收所述基站发送的第一能力信息，其中，所述第一能力信息用于指示所述基站对终端进行多SIM卡连接切换的支持能力。
在一个实施例中，基站可以根据自身对于多SIM卡连接切换的支持能力生成第一能力信息，进而将第一能力信息发送给核心网，核心网在接收到第一能力信息后，就可以根据第一能力信息确定基站对于终端进行多SIM卡连接切换的支持能力，例如是否支持多SIM卡连接切换，例如在支持多SIM卡连接切换的情况下，具体支持何种条件下的多SIM卡连接切换。
在一个实施例中，所述第一能力信息还用于指示与所述基站连接的其他基站对终端进行多SIM卡连接切换的支持能力。
基站之间可以通过建立接口形成通信连接，例如基站A和基站B之间可以建立接口，例如X2接口、Xn接口，例如基站B可以是基站A的邻基站。基站A和基站B之间可以通过接口通信，例如基站B可以将自身对于多以SIM卡连接切换的支持能力告知基站A，进而基站A可以在第一能力信息中携带基站A对于多SIM卡连接切换的支持能力和基站B对于多SIM卡连接切换的支持能力发送至核心网。
据此，在核心网与一个基站之间存在通信连接情况下，可以获取到至少一个基站对于多SIM卡连接切换的支持能力，有利于提高基站与核心网之间通信资源的使用效率。
在一个实施例中，所述方法还包括：将所述第一能力信息(例如可以通过非接入层信令携带)发送至终端。需要说明的是，核心网也可以将第二能力发送至终端。
在一个实施例中，核心网可以将多个基站对于多SIM卡连接切换的第一能力信息发送给终端，终端可以确定自身对于多SIM卡连接切换的支持能力，进而确定对于多SIM卡连接切换的支持能力与终端对于多SIM卡连接切换的支持能力相匹配的基站网。
例如终端自身支持在第一SIM卡保持在连接态的情况下，进行多SIM卡连接切换，在接收到的多个终端对于多SIM卡连接切换的能力信息中，可以确定基站X支持在第一SIM卡保持在连接态的情况下，进行多SIM卡连接切换，基站Y则仅支持在第一SIM卡离开连接态的情况下，进行多SIM卡连接切换，那么可以确定基站X对于多SIM卡连接切换的支持能力与终端自身对于多SIM卡连接切换的支持能力是匹 配的。
进而终端对于基站X和基站Y，可以优先选择基站X接入，例如可以优先选择基站X对应的小区进行驻留、小区重选等操作。据此，可以确保终端在接入基站X后，在进行多SIM卡连接切换时，将多SIM卡连接切换的信息上报至基站X后，基站X有能力对终端进行多SIM卡连接切换做出合理的配置。
图12是根据本公开的实施例示出的又一种能力指示方法的示意流程图。如图12所示，所述将所述第一能力信息发送至终端还包括：
在步骤S1201中，确定第三条件；
在步骤S1202中，根据所述第一能力信息确定第四能力信息，其中，所述第四能力信息用于指示所述核心网对终端在第三条件下进行多SIM卡连接切换的支持能力；
在步骤S1203中，将所述第四能力信息发送至所述终端。
在一个实施例中，由于第一能力信息中可以携带多种支持能力，例如可以包括支持多SIM卡连接切换、支持第一SIM卡保持在连接态的情况下进行多SIM卡连接切换、支持第一SIM卡离开连接态的情况下进行多SIM卡连接切换等，但是终端可能并不需要确定对于每种情况多SIM卡连接切换的支持能力，而是只希望确定对于部分情况多SIM卡连接切换的支持能力。
例如终端自身支持在第三条件下进行多SIM卡连接切换，那么终端可以仅需要确定基站是否也支持在第三条件进行多SIM卡连接切换，而对于在其他条件下的多SIM卡连接切换则不感兴趣。在这种情况下，核心网可以确定第三条件，例如第三条件可以由终端上报，也可以与终端预先约定，进而可以基于第三条件在第一能力信息中确定第四能力信息，确定的第四能力信息是第一能力信息中针对第三条件下进行多SIM卡连接切换的支持能力，进而将第四能力信息发送至终端。
由于第四能力信息为第一能力信息中的部分能力信息，一般情况下占用的通信资源相对较少，一方面可以满足终端需要，另一方面有利于节约通信资源。
图13是根据本公开的实施例示出的又一种能力指示方法的示意流程图。如图13所示，所述将所述第一能力信息发送至终端包括：
在步骤S1301中，确定满足第二条件的目标终端，其中，所述第二条件包括以 下至少之一：终端中设置有多个SIM卡、终端支持多SIM卡连接切换；
在步骤S1302中，将所述第一能力信息发送至所述目标终端。
在一个实施例中，核心网可以选择性地向终端发送第一能力信息，例如可以确定满足第二条件的目标终端，例如目标终端可以是指设置有多个SIM卡的终端，也可以是指支持多SIM卡连接切换的终端，针对这些终端，终端才有可能进行多SIM卡连接切换，进而才有获取第二能力信息的需要，因此可以仅向这些终端发送第一能力信息，有利于避免给不需要获取第一能力信息的终端而造成通信资源的浪费。
图14是根据本公开的实施例示出的一种能力确定方法的示意流程图。本实施例所示的能力确定方法可以由终端执行，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置，所述终端可以与基站、核心网等网络侧设备通信，所述网络侧设备包括但不限于4G、5G、6G等通信系统中的网络侧设备。
如图14所示，所述能力确定方法可以包括以下步骤：
在步骤S1401中，接收第一网络侧设备从第二网络侧设备获取到的能力信息；
在步骤S1402中，根据所述能力信息确定所述第二网络侧设备对终端进行多SIM卡连接切换的支持能力。
在一个实施例中，所述终端中设置有多个SIM卡，所述多个SIM卡至少包括第一SIM卡和第二SIM卡，所述多SIM卡连接切换包括在通过第一SIM卡进行通信操作时，切换到第二SIM卡进行通信操作(在这种情况下第一SIM卡进行的通信操作可以中断)。需要说明的是，多SIM卡连接切换并不限于上述情况，例如还可以包括通过第一SIM卡进行通信操作时，启动第二SIM卡同时进行通信操作(在这种情况下第一SIM卡进行的通信操作可以不中断)。以下主要针对多SIM卡连接切换包括通过第一SIM卡进行通信操作时，切换到第二SIM卡进行通信操作的情况，对本公开的技术方案进行示例性说明。
针对这种情况，需要基站、核心网等网络侧设备针对终端做出适当的操作和配置。以网络侧设备包括基站为例，例如终端通过第一SIM卡与第一基站通信时，需要通过第二SIM卡与第二基站通信，例如接收第二基站发送的系统信息，那么就第一基站与第一SIM卡之间的通信操作就需要中断一段时间，在通过第二SIM卡与第一基站通信完毕后，第一基站再恢复与第一SIM卡之间的通信操作。
但是，并非所有网络侧设备都支持第一SIM卡通信操作中断后再恢复。例如， 有的网络侧设备能够针对终端进行多SIM连接切换的情况做出适当的操作和配置，也即支持多SIM卡连接切换，有的网络侧设备则不能，也即不支持多SIM卡连接切换。并且对于支持多SIM卡连接切换的网络侧设备，对于多SIM卡连接切换的具体支持情况也可能有所不同，例如网络侧设备可以支持第一SIM卡离开连接态时的多SIM卡连接切换，或者支持第一SIM卡保持在连接态时的多SIM卡连接切换。
考虑到上述技术问题，本公开的实施例中，第二网络侧设备可以根据自身对于多SIM卡连接切换的支持能力生成能力信息，进而将能力信息发送给第一网络侧设备，第一网络侧设备在接收到能力信息后，就可以根据能力信息确定第二网络侧设备对于终端进行多SIM卡连接切换的支持能力，例如是否支持多SIM卡连接切换，例如在支持多SIM卡连接切换的情况下，具体支持何种条件下的多SIM卡连接切换。进而后续第一网络侧设备可以根据需要将第二网络侧设备对于多SIM卡连接切换的支持能力告知终端，以便终端据此确定是否接入第二网络侧设备。
在一个实施例中，所述第一网络侧设备包括基站，所述第二网络侧设备包括核心网；或者，所述第一网络侧设备包括核心网，所述第一网络侧设备包括基站。
图15是根据本公开的实施例示出的另一种能力确定方法的示意流程图。如图15所示，所述第一网络侧设备包括基站，所述第二网络侧设备包括核心网，所述方法还包括：
在步骤S1501中，根据所述能力信息确定对终端进行多SIM卡连接切换的支持能力以及与所述终端进行多SIM卡连接切换的能力匹配的目标核心网；
在步骤S1502中，向所述目标核心网进行附着或注册。
在一个实施例中，基站可以将多个核心网对于多SIM卡连接切换的能力信息发送给终端，终端可以确定自身对于多SIM卡连接切换的支持能力，进而确定对于多SIM卡连接切换的支持能力与终端对于多SIM卡连接切换的支持能力相匹配的核心网。
例如终端自身支持在第一SIM卡保持在连接态的情况下，进行多SIM卡连接切换，在接收到的多个核心网对于多SIM卡连接切换的能力信息中，可以确定核心网X支持在第一SIM卡保持在连接态的情况下，进行多SIM卡连接切换，核心网Y则仅支持在第一SIM卡离开连接态的情况下，进行多SIM卡连接切换，那么可以确定核心网X对于多SIM卡连接切换的支持能力与终端自身对于多SIM卡连接切换的支持能力是匹配的。
进而终端对于核心网X和核心网Y，可以优先选择核心网X接入，例如可以优先选择核心网X进行注册或附着。据此，可以确保终端在接入核心网X后，在进行多SIM卡连接切换时，将多SIM卡连接切换的信息上报至核心网X后，核心网X有能力对终端进行多SIM卡连接切换做出合理的配置。
图16是根据本公开的实施例示出的又一种能力确定方法的示意流程图。如图16所示，所述第一网络侧设备包括核心网，所述第二网络侧设备包括基站，所述方法还包括：
在步骤S1601中，根据所述能力信息确定对终端进行多SIM卡连接切换的支持能力以及与所述终端进行多SIM卡连接切换的能力匹配的目标基站；
在步骤S1602中，向所述目标基站进行驻留或小区重选。
在一个实施例中，核心网可以将多个基站对于多SIM卡连接切换的能力信息发送给终端，终端可以确定自身对于多SIM卡连接切换的支持能力，进而确定对于多SIM卡连接切换的支持能力与终端对于多SIM卡连接切换的支持能力相匹配的基站网。
例如终端自身支持在第一SIM卡保持在连接态的情况下，进行多SIM卡连接切换，在接收到的多个终端对于多SIM卡连接切换的能力信息中，可以确定基站X支持在第一SIM卡保持在连接态的情况下，进行多SIM卡连接切换，基站Y则仅支持在第一SIM卡离开连接态的情况下，进行多SIM卡连接切换，那么可以确定基站X对于多SIM卡连接切换的支持能力与终端自身对于多SIM卡连接切换的支持能力是匹配的。
进而终端对于基站X和基站Y，可以优先选择基站X接入，例如可以优先选择基站X对应的小区进行驻留、小区重选等操作。据此，可以确保终端在接入基站X后，在进行多SIM卡连接切换时，将多SIM卡连接切换的信息上报至基站X后，基站X有能力对终端进行多SIM卡连接切换做出合理的配置。
