具体实施方式
首先，对本申请提供的技术方案可适用的通信系统进行说明。
本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(long term evolution,LTE)系统、或第五代(5th generation,5G)通信系统、或无线保真(wireless-fidelity，Wi-Fi)系统、或多种通信系统融合的系统、或未来演进的通信系统，以及其他可用于提供通信服务的网络系统，此处不做限定。
图1示例性的给出了一种可能的通信系统结构示意图。该通信系统包括至少一个核心网设备(图中示出了第一核心网设备110和第二核心网设备120)，与核心网设备连接的一个或多个接入网设备，(图中示出了第一接入网设备130和第二接入网设备140)，以及与接入网设备连接的终端设备150。图1中所示终端设备150为DSDS终端设备，该终端设备可以同时支持两张SIM卡。
图2示出了通信系统的一种可能的架构举例示意图，如图2所示无线接入网(radio access network，RAN)中的网络设备是集中单元(centralized unit，CU)和分布单元(distributed unit,DU)分离架构的基站(如gNodeB或gNB)。RAN可以与核心网相连(例如可以是LTE的核心网，也可以是5G的核心网等)。CU和DU可以理解为是对基站从逻辑功能角度的划分。CU和DU在物理上可以是分离的也可以部署在一起。多个DU可以共用一个CU。一个DU也可以连接多个CU(图中未示出)。CU和DU之间可以通过接口相连，例如可以是F1接口。
可选的，CU和DU可以根据无线网络的协议层划分。例如无线资源控制(radio resource control，RRC)、业务数据适配协议栈(service data adaptation protocol，SDAP)以及分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能设置在CU，而无线链路控制(radio link control，RLC)，媒体接入控制(media access control，MAC)层，物理(physical，PHY)层等的功能设置在DU。需要理解的是，对CU和DU处理功能按照这种协议层的划分仅仅是一种举例，也可以按照其他的方式进行划分。
可选的，CU或DU还可以划分为具有协议层的部分处理功能。在一种可能的设计中，将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。在另一种可能的设计中，还可以按照业务类型或者其他系统需求对CU或者DU的功能进行划分，例如按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。图2所示的网络架构可以应用于5G通信系统，其也可以与LTE系统共享一个或多个部件或资源。在另一种设计中，CU也可以具有核心网的一个或多个功能。一个或者多个CU可以集中设置，也分离设置。例如CU可以设置在网络侧方便集中管理。DU可以具有多个射频功能，也可以将射频功能拉远设置。
可选的，CU的功能可以由一个实体来实现也可以由不同的实体实现。例如，可以对CU的功能进行进一步分割，例如，将控制面(control plane,CP)和用户面(user plane,UP)分离，即CU控制面(CU-CP)和CU用户面(CU-UP)。例如，CU-CP和CU-UP可以由不同的功能实体来实现，所述CU-CP和CU-UP可以与DU相耦合，共同完成基站的功能。一种可能的方式中，CU-CP负责控制面功能，主要包含RRC和PDCP-C。PDCP-C主要负责控制面数据的加解密，完整性保护，序列号维护，数据传输等；CU-UP负责用户面功能，主要包含SDAP和PDCP-U，其中SDAP主要负责将核心网的数据进行处理并将数据流(flow)映射到承载。PDCP-U主要负责数据面的加解密，完整性保护，头压缩，序列号维护，数据传输等，其中CU-CP和CU-UP通过E1接口连接。
可以理解的是，本申请中提供的实施例也适用于CU和DU不分离的架构。

可以理解的是，本申请的实施例对终端设备的应用场景不做限定。
在无线通信网络中，终端设备可以存在支持多个SIM卡的应用场景，多个SIM卡之间可能存在寻呼冲突问题，例如，DSDS手机中两个SIM卡(例如，SIM A和SIM B)共用一个收发机，如果SIM A和SIM B的寻呼时机有重叠，即算出来的寻呼帧或寻呼时机有冲突，则会导致SIM A或SIM B的寻呼消息不能及时收到。因此，如何能够有效的实现DSDS的手机的寻呼，成为亟需解决的问题。可以理解，本申请中以终端设备支持两张SIM卡为例介绍本申请提出的技术方案，该技术方案也可适用于终端支持三个、四个甚至更多个SIM卡的场景。
本申请提供的方法中，终端设备至少有一个SIM卡处于非连接态(非连接态包括：空闲态或非激活态)，终端设备通过在单个SIM卡(例如SIM A)对应的小区接收与寻呼相关的消息或者信息来实现对该终端设备的多张SIM卡的寻呼的监听。例如，SIM A对应的网络侧设备A和SIM B对应的网络侧设备B之间完成关联后，网络侧设备B需要寻呼SIM B时，网络侧设备A向SIM A对应的小区发送寻呼信息用于寻呼SIM B。该方法可以避免终端设备频繁进行收发机的转换，避免寻呼时机重叠时，总是收不到某个SIM卡的寻呼消息。容易理解的，本申请中，终端设备支持的两张SIM卡可以称为第一SIM卡和第二SIM卡，本申请 并不限定。
可以理解，在终端支持三个、四个甚至更多个SIM卡的场景下，本申请提供的方法也适用，例如，终端设备通过在单个SIM卡(例如SIM A)对应的小区接收与寻呼相关的消息或者信息来实现对该终端设备的多张SIM卡的寻呼的监听。多个SIM卡对应的网络侧设备之间完成关联后，除SIM A对应的网络侧设备以外的其他SIM卡对应的网络侧设备需要寻呼其他SIM卡(例如SIM B、SIM C、或SIM D等)时，均通过SIM A对应的网络侧设备向SIM A对应的小区发送寻呼消息用于寻呼其他SIM卡。

以下实施例中，以终端设备同时支持第一用户身份(第一SIM卡对应的用户身份)和第二用户身份(第二SIM卡对应的用户身份)举例说明。本申请实施例中，终端设备通过在单个用户身份对应的小区的上接收消息或者信息，来实现对多个用户身份的寻呼信息的监听。
例如，一种实施方式中，终端设备以第一用户身份处于连接态，并且，终端设备以第二用户身份处于空闲态或非激活态，终端设备通过在第一用户身份对应的小区接收对应第二用户身份的寻呼信息。可以理解的是，当该终端设备以第一用户身份改变到空闲态时，对应于第一用户身份的寻呼信息也是通过第一用户身份对应的小区来接收。
又一种实施方式中，终端设备以第一用户身份和第二用户身份均处于空闲态，或者，终端设备以第一用户身份和第二用户身份均处于非激活态，可以将该终端设备中的第一用户身份和第二用户身份中任一个对应的小区作为接收该两个用户身份对应的寻呼信息的小区(该小区可以称为第一小区或者主小区)。例如，终端设备可以在第一用户身份对应的小区监听寻呼消息，来实现对第一用户身份和第二用户身份的寻呼信息的监听。其中，将该终端设备中的第一用户身份和第二用户身份中任一个对应的小区作为接收该两个用户身份对应的寻呼信息的小区也可以理解为将第一SIM卡和第二SIM卡中的任意一张卡作为接收该两个用户身份对应的寻呼信息的SIM卡(例如可以称为主卡)。
又一种实施方式中，终端设备以第一用户身份处于非激活态，终端设备以第二用户身份处于空闲态，终端设备通过在第一用户身份对应的小区上接收消息或信息，来实现对第一身份用户和第二用户身份的寻呼信息的监听。
可以理解的是，确定哪张卡作为上述主卡可以是预定义的，例如支持高级别制式的SIM卡为主卡。比如，第一SIM卡为支持5G的卡，第二SIM卡为支持4G的卡，那么 根据预定义，可以将第一SIM作为主卡。或者，也可以预定义特定制式的SIM卡为主卡。本申请实施例对于预定义的方式不做限定
又一种可能的方式中，上述主卡也可以是由终端设备选择并指示给一个或者多个网络侧设备的。例如，终端设备可以根据预设条件选择主卡，或者也可以任意选择，本申请实施例对于终端设备如何选择主卡以及如何将选择的结果指示给网络侧设备的方式不做限定。
下面结合具体的场景，分别描述可能的通信方法的流程。
例如，图3为本申请实施例提供的一种通信方法300的交互示意图。图3中以终端设备、第一网络侧设备和第二网络侧设备作为该交互示意的执行主体为例来示意该通信方法，但本申请并不限制该交互示意的执行主体。
可以理解的是，图3中由网络侧设备(例如第一网络侧设备或者第二网络侧设备)实现的步骤或者流程也可以由支持该网络侧设备实现该方法的芯片、芯片系统、或处理器等实现。图3中的由终端设备实现的步骤或者流程也可以是由支持该终端设备实现该方法的芯片、芯片系统、或处理器等实现。

本实施例中，第一网络侧设备和第二网络侧设备均为接入网设备。
如图3所示，该实施例的方法300可以包括：
操作310：终端设备以第一用户身份向第一网络侧设备发送第一信息。
相应的，该第一网络侧设备接收该第一信息。
其中，该第一信息可以指示对应于第二用户身份的第一标识信息。一种可能的方式中，该第一标识信息可以是第二网络侧设备为对应于第二用户身份的终端设备分配的。可以理解的是，第二网络侧设备可以是配置终端设备以第二用户身份进入非激活(inactive)态的锚点基站，那么该第一标识信息可以包括非激活态无线网络临时标识(inactive radio network temporary identifier,I-RNTI)。此处，第二网络侧设备配置终端设备以第二身份进入inactive态，也可以称为第二网络侧设备配置第二SIM卡进入inactive态。可选的，第一标识信息还可以包括I-RNTI和终端设备以第二用户身份连接的物理小区标识以及第二网络侧设备的标识。可选的，第一标识信息还可以包括I-RNTI和服务小区的全球小区识别码(cell global identification,CGI)。可以理解的是，某些场景下，第一信息也可以替换为第一标识信息。
第一网络侧设备在接收到第一信息后，可以根据该第一信息确定第一用户身份和第二用户身份都对应该终端设备，也就是说该第一网络侧设备获知第一用户身份和第二用户身份是关联的。
可以理解的是，本申请实施例中，对应于某个用户身份的信息(例如标识信息或者其他信息)，也可以理解为对应于某个SIM卡的信息；以某个用户身份实现某个操作(例如发送信息或者消息)，也可以理解为通过某个SIM卡实现某个操作，以下不重复说明。
操作310中，终端设备以第一用户身份向第一网络侧设备发送第一信息可能有多种不同的实现方式：例如，终端设备可以在以第一用户身份进行连接态时，向第一网络侧设备发送该第一信息；或者，也可以是在第一用户身份处于连接态一段时间后，向第一网络侧设备发送该第一信息；或者，也可以是在终端设备以第一用户身份获取到该第一信息中的第一标识信息时，就向第一网络侧设备发送该第一信息；或者，也可以是在以第一用户身份与第一网络侧设备建立连接时，向第一网络侧设备发送该第一信息。
可以理解的是，该终端设备同时支持第一用户身份和第二用户身份，终端设备可以通过内部交互以第一用户身份获取第二用户身份的标识。
以上实施方式中，一种可能的方式中，终端设备和第二网络侧设备之间可以通过Uu接口消息进行交互，例如在RRC连接释放时，第二网络侧设备通过RRC连接释放消息向终端设备发送I-RNTI。本申请实施例对于终端设备向第二网络侧设备发送第一信息的时机和方式不做限定。
可选的，该终端设备还可以以第一用户身份向第二网络侧设备发送寻呼冲突的指示信息，以用于向该第二网络侧设备指示存在寻呼冲突的可能。可以理解的是，该指示信息不是必须的，一种可选的方案中，通过发送第一标识信息可以隐式的指示存在寻呼冲突。
可选的，该终端设备还可以以第一用户身份向第二网络侧设备发送终端监听指示信息，以用于向该第二网络侧设备指示终端设备以第一用户身份(或者说通过第一SIM卡)监听寻呼信息。可以理解的是，该监听指示信息不是必须的。
可以理解的，第一信息、寻呼冲突指示信息和监听指示信息可以是通过同一条消息发送的，例如，第一消息中携带寻呼冲突指示信息和/或监听指示信息；也可以是通过不同的消息发送的，本申请实施例对此并不限定。
通过上述操作310，终端设备向第一网络侧设备指示终端设备的第一用户身份和终端设备的第二用户身份与该终端设备关联的信息，有助于完成终端设备多个用户身份在网络侧的关联。
操作320：终端设备以第二用户身份向第二网络侧设备发送第二信息。
其中，该第二信息可以指示对应于第一用户身份的第二标识信息。一种可能的方式中，该第二标识信息可以是第一网络侧设备为对应于第一身份的终端设备分配的。可以理解的是，第一网络侧设备可以是配置终端设备以第一用户身份进入连接态的锚点基站，那么该第二标识信息可以包括小区无线网络临时标识(cell radio network temporary identifier,C-RNTI)和以第一用户身份连接的物理小区标识以及第一网络侧设备的标识。可选的，该第二标识信息也可以包括第一用户身份的C-RNTI和服务小区的CGI。可以理解的是，在某些场景下，第二信息也可以替换为第二标识信息。
另一种可能的方式中，第一网络侧设备可以是配置终端设备以第一用户身份进入非激活态的锚点基站，那么该第二标识信息可以包括I-RNTI和终端设备以第一用户身份连接的物理小区标识以及第一网络侧设备的标识。可选的，该第二标识信息也可以包括第一用户身份的I-RNTI和服务小区的CGI。
第二网络侧设备在接收到该第二信息后，可以根据该第二信息确定第一用户身份和第二用户身份都对应该终端设备，也就是说该第二网络侧设备获知第一用户身份和第二用户身份是关联的。
操作320中，终端设备以第二用户身份向第二网络侧设备发送第二信息可能有多种 不同的实现方式：例如，终端设备可以在以第二用户身份进入非激活态前的某个时机，即在第二用户身份处于连接态时，向第二网络侧设备发送该第二信息；或者，也可以是终端设备以第二用户身份，利用inactive态中的消息(例如恢复请求消息)将第二信息发送给第二网络侧设备。
可选的，该终端设备还可以以第二用户身份向第二网络侧设备发送寻呼冲突指示信息，以用于向该第二网络侧设备指示存在寻呼冲突的可能。可以理解的是，该指示信息不是必须的，一种可选的方案中，通过发送第二标识信息可以隐式的指示存在寻呼冲突。
可选的，该终端设备还可以以第二用户身份向第二网络侧设备发送终端监听指示信息，以用于向该第二网络侧设备指示终端设备以哪个用户身份(或者说通过哪个SIM卡)监听寻呼信息。例如，一种可选的方案中，该监听指示信息可以携带第一用户身份的标识，以用于指示终端监听的用户身份为第一用户身份。可以理解的是，该监听指示信息不是必须的，一种可选的方案中，通过发送第二标识信息可以隐式的指示终端设备以第一用户身份(或者说通过第一SIM卡)监听寻呼信息。
可以理解的，第二消息、寻呼冲突指示信息和监听指示信息可以是通过同一条消息发送的，例如，第二消息中携带寻呼冲突指示信息和/或监听指示信息；也可以是通过不同的消息发送，本申请实施例并不限定。
容易理解地，操作310和操作320可以都执行，也可以只执行操作310，也可以只执行操作320。此外，本申请实施例中，对于操作310和320的先后顺序不做限定。
通过上述操作320，终端设备向第二网络侧设备指示终端设备的第一用户身份和终端设备的第二用户身份与该终端设备关联的信息，有助于完成终端设备的多个用户身份在网络侧的关联。
操作330：第一网络侧设备和第二网络侧设备之间完成关于第一用户身份和第二用户身份的关联。
可以理解，针对操作310和320是否被执行的不同场景，操作330可能存在不同的实施方式。
例如，在操作310被执行(可以是仅操作310被执行，也可以是操作310和操作320均被执行)的场景中，操作330的一种可能实施方式可以包括：第一网络侧设备根据操作310中接收的第一标识确定出该第二用户身份对应的锚点基站，也就是第二网络侧设备；第一网络侧设备请求与该第二网络侧设备关联。其中，可选的，第一网络侧设备可以通过向第二网络侧设备发送第一标识信息来请求第二网络侧设备完成关于第一用户身份和第二用户身份的关联，从而可以使得第二网络侧设备获知可以通过第一网络侧设备发送相关信息，进一步的，也可以理解为第二网络侧设备获知第一用户身份和第二用户身份属于同一终端设备。可选的，第一网络侧设备也可以将第二标识信息发送给第二网络侧设备。
可选的，第二网络侧设备可以响应于第一网络侧设备的请求，向第一网络侧设备指示确认关联。可以理解的是，该响应步骤不是必需的，也可以认为第二网络侧设备接收到第一网络侧设备发送的第一标识信息，或者第一标识信息和第二标识信息后，就完成了关联操作。
在操作320被执行(可以是仅操作320被执行，也可以是操作310和操作320均被执行)的场景中，操作330的一种可能实施方式可以包括：第二网络侧设备根据操作320中接收的第二标识确定出该第一用户身份对应的基站，也就是第一网络侧设备。第二网 络侧设备请求与该第一网络侧设备关联。其中，可选的，第二网络侧设备可以通过向第一网络侧设备发送第二标识信息来请求第一网络侧设备完成关于第一用户身份和第二用户身份的关联，从而可以使得第一网络侧设备获知可以通过第二网络侧设备发送相关信息，进一步的，也可以理解为第一网络侧设备获知第一用户身份和第二用户身份属于同一终端设备。可选的，第二网络侧设备也可以将第一标识信息发送给第一网络侧设备。
可选的，第一网络侧设备可以响应于第二网络侧设备的请求，向第二网络侧设备指示确认关联。可以理解的是，该响应步骤不是必需的，也可以认为第一网络侧设备接收到了第二网络侧设备发送的第二标识信息，或者第一标识信息和第二标识信息后，就完成了关联操作。
以上实施方式中，第一网络侧设备和第二网络侧设备之间可以通过Xn接口消息或者X2接口消息进行交互，本申请实施例对于第一网络侧设备和第二网络侧设备之间消息交互的名称和时机不做限定。此外，以上实施方式中，是通过发送终端设备的标识信息的方式实现操作330，也可能有其他的方式实现操作330，例如通过发送指示信息A，使得第二网络侧设备获知通过第一网络侧设备寻呼上述终端设备，该指示信息A可以使得第二网络侧设备获知可以通过第一网络侧设备寻呼上述终端设备即可，对于指示信息A的内容不做限定。
可以理解的，本实施例以终端设备在第一用户身份对应的小区的上接收消息或者信息，来实现对多个用户身份的寻呼信息的监听为例介绍方法300，但本申请并不限定。
通过上述操作330，第一网络侧设备和第二网络侧设备完成终端设备的第一用户身份和终端设备的第二用户身份的关联，有助于终端设备实现接收单个用户身份的寻呼消息来实现对多个用户身份的寻呼信息的监听的功能。
操作340：第二网络侧设备向第一网络侧设备发送寻呼指示信息，该寻呼指示信息用于指示寻呼上述终端设备对应的第二用户身份。
如果第二网络侧设备需要寻呼第二SIM卡(也就是说寻呼该终端设备对应的第二用户身份)，第二网络侧设备可以通过第一网络侧设备来实现该寻呼：第二网络侧设备将相应的寻呼信息发给第一网络侧设备，使得第一网络侧设备知道第二网络侧设备要寻呼该第二SIM卡。
相应的，第一网络侧设备接收该寻呼指示信息。
可选的，在第二网络侧设备向第一网络侧设备发送寻呼指示信息前，第二网络侧设备确定通过第一网络侧设备寻呼该终端设备对应的第二用户身份。
一种可能的方式可以为，在操作330完成后，第二网络侧设备也就确定通过第一网络设备寻呼该终端对应的第二用户身份。
第二网络侧设备确定通过第一网络侧设备寻呼第二用户身份的又一种可能的方式可以包括：该第二网络侧设备从第一网络侧设备接收连接态指示信息，该连接态指示信息指示该终端设备以第一用户身份处于连接态。
在第二网络侧设备确定通过第一网络侧设备寻呼第二用户身份的另一种可能的方式可以包括：该第二网络侧设备从终端设备接收寻呼冲突的指示信息，该寻呼冲突的指示信息指示第一用户身份和第二用户身份之间存在寻呼冲突的可能，可选的，该寻呼冲突指示信息还可以包括指示该第二网络侧设备需要通过第一网络侧设备寻呼第二用户身份。例如，该冲突指示信息还携带第一网络侧设备的标识。
第二网络侧设备确定通过第一网络侧设备寻呼第二用户身份的再一种可能的方式可 以包括：该第二网络侧设备从终端设备接收监听指示信息，该监听指示信息指示终端设备在第一用户身份对应的小区上接收消息或者信息，来实现对多个用户身份的寻呼信息的监听。例如，该监听指示信息携带上述第二标识信息。
通过上述操作340，第二网络侧设备通过第一网络侧设备寻呼终端设备的第二用户身份，也就是说，第二网络侧设备在需要寻呼第二用户身份时，确定通过第一网络侧设备寻呼终端设备的第二用户身份。
操作350：第一网络侧设备向对应第一用户身份的终端设备指示寻呼第二用户身份。
也就是说，第二网络侧设备在需要寻呼该终端设备的第二用户身份时，通过第一用户身份所对应的网络或者小区或者信道或者链路寻呼该终端设备的第二用户身份。
可以理解，针对终端设备以第一用户身份和第二用户身份处于状态的不同场景，操作350可能存在不同的实施方式。
例如，在终端设备以第一用户身份处于连接态，终端设备以第二身份处于非激活态的场景下，操作350的一种可能实施方式可以包括：第一网络侧设备向对应第一用户身份的终端设备发送无线资源控制(radio resource control,RRC)消息，该RRC消息包括指示寻呼第二用户身份的信息，该指示寻呼第二用户身份的信息表示第二网络侧设备寻呼该终端设备的第二用户身份。例如，该RRC消息中可以包含上述寻呼指示信息中的内容。或者该RRC消息中可以包括寻呼信息，该寻呼信息可以是在寻呼指示信息基础上进行处理后的寻呼信息。本申请实施例中，对于该RRC消息的内容不做限定，只要能使得该终端设备获知第二网络侧设备寻呼该第二用户身份即可。
终端设备以第一用户身份接收该RRC消息，该终端设备根据该RRC消息获知第二网络侧设备寻呼第二用户身份，从而该终端设备以第二用户身份尝试进入连接态。也就是说终端设备的第二用户身份被寻呼后，会尝试恢复与网络侧设备的连接，如果成功，则终端设备可以以第二用户身份进入连接态。
可选的，该RRC消息中可以包括第二用户身份对应的终端设备标识信息，或者，包括第一用户身份对应的终端设备标识信息和第二用户身份对应的终端设备标识信息。一种可能的方式中，该终端设备根据接收到的RRC消息中的终端设备标识信息确定该RRC消息指示第二网络侧设备寻呼第二用户身份。
需要说明的是，终端设备以第一用户身份处于连接态，也就是说该终端设备的第一SIM卡处于连接态，终端设备以第二身份处于非激活态，也就是说该终端设备的第二SIM卡处于非激活态。
在终端设备以第一用户身份处于非激活态，终端设备以第二身份处于非激活态的场景下，操作350的一种可能实施方式可以包括：第一网络侧设备向对应第一用户身份的终端设备发送无线接入网络寻呼消息中，该无线接入网络寻呼消息包括指示寻呼第二用户身份的信息，该指示寻呼第二用户身份的信息表示第二网络侧设备寻呼该终端设备的第二用户身份。例如，该无线接入网络寻呼消息中可以包含上述寻呼指示信息中的内容。或者该无线接入网络寻呼消息中可以包括寻呼信息，该寻呼信息可以是在寻呼指示信息基础上进行处理后的寻呼信息。本申请实施例中，对于该无线接入网络寻呼消息的内容不做限定，只要能使得该终端设备获知第二网络侧设备寻呼该第二用户身份即可。
终端设备以第一用户身份接收该无线接入网络寻呼消息，该终端根据该无线接入网络寻呼消息获知第二网络侧设备寻呼第二用户身份，从而该终端设备以第二用户身份尝试进入连接态。可选的，该无线接入网络寻呼消息中可以包括第二用户身份对应的终端设备标 识信息，或者，包括第一用户身份对应的终端设备标识信息和第二用户身份对应的终端设备标识信息。终端设备根据该标识确定该无线接入网络寻呼消息指示寻呼第二用户身份。
方法300中，第一网络侧设备和第二网络侧设备完成关联后，第二网络侧设备在需要寻呼第二用户身份时，向第一用户身份发送寻呼指示信息用于指示寻呼第二用户身份，通过上述实施方法，解决了终端设备监听网络侧设备发起的寻呼消息的潜在冲突，保证终端设备能够为两个用户身份及时接收网络侧设备的寻呼消息。
可选的，图3所示实施例中，是以第一网络侧设备和第二网络侧设备为不同的网络侧设备进行描述的，容易理解地，第一网络侧设备和第二网络侧设备也可以是同一个网络侧设备，当第一网络侧设备和第二网络侧设备是同一个网络侧设备时，如图3A所示，本申请实施例又提供一种通信方法301。方法301可以包括操作310A、操作320A和操作350A。
操作310A：终端设备以第一用户身份向第一网络侧设备发送第一信息。
相应的，该第一网络侧设备接收该第一信息。关于操作310A可以参考方法300中关于操作310的描述。
操作320A：终端设备以第二用户身份向第一网络侧设备发送第二信息。
相应的，该第一网络侧设备接收该第二信息。关于操作320A可以参考方法300中关于操作320的描述，进一步地，与方法300中的操作320不同的是，方法301中的操作320A为向第一网络侧设备发送第二信息。
容易理解地，操作310A和操作320A可以都执行，也可以只执行操作310A，也可以只执行操作320A。此外，本申请实施例中，对于操作310A和320A的先后顺序不做限定。
例如，在操作310A被执行(可以是仅操作310A被执行，也可以是操作310A和操作320A均被执行)的场景中，第一网络侧设备根据操作310中的接收的第一标识确定第二用户身份对应的锚点基站，也是第一网络侧设备。第一网络设备获知第一用户身份和第二用户身份属于同一终端设备。
在操作320A被执行(可以是仅操作320A被执行，也可以是操作310A和操作320A均被执行)的场景中，第一网络侧设备根据操作320A中的接收的第二标识确定第一用户身份对应的锚点基站，也是第一网络侧设备。第一网络侧设备获知第一用户身份和第二用户身份属于同一终端设备。
操作330A：第一网络侧设备向对应第一用户身份的终端设备发送寻呼信息，该寻呼信息用于指示寻呼第二用户身份。
与方法300相比，方法301中不存在第一网络侧设备和第二网络侧设备之间关于完成关联操作的相关交互。第一网络侧设备在需要寻呼该终端设备的第二用户身份时，通过第一用户身份所对应的网络或者小区或者信道或者链路寻呼该终端设备的第二用户身份，其中，具体的寻呼该终端设备的第二用户身份的方式可以参考可以参考方法300中关于操作350的描述。

图4为本申请实施例提供的一种通信方法400的交互示意图。图4中以终端设备、第一接入网设备、第一网络侧设备和第二网络侧设备作为该交互示意的执行主体为例来示意该通信方法，但本申请并不限制该交互示意的执行主体。

本申请实施例中的终端设备为双卡双待终端，该终端设备同时支持第一用户身份(第一SIM卡对应的用户身份)和第二用户身份(第二SIM卡对应的用户身份)。该第一网络侧设备为第一用户身份提供服务，该第二网络侧设备为第二用户身份提供服务，该第一接入网设备为第一用户身份服务。本申请实施例中，网络侧设备为特定用户身份提供服务，可以理解为终端设备的该特定用户身份对应的网络侧设备是该网络侧设备，也就是说终端设备与该特定用户身份对应的业务通过该网络侧设备实现。
本实施例中，第一网络侧设备和第二网络侧设备均为核心网设备，因此，第一网络侧设备也可以称为第一核心网设备，第二网络侧设备也可以称为第二核心网设备。
可以理解的是，终端设备的第一SIM卡和第二SIM卡会在各自对应的核心网设备进行注册。例如，终端设备以第一用户身份将第一用户身份对应的全球唯一不变的识别码(例如第一国际移动用户识别码IMSI)发送给第一核心网设备，终端设备以第二用户身份将第二用户身份对应的全球唯一不变的识别码(例如第二IMSI)发送给第二核心网设备，而第一核心网设备和第二核心网设备会分别为该终端设备的第一用户身份和第二用户身份分配可以在核心网范围内识别该终端设备的终端设备标识。例如，在LTE系统中，该终端设备标识可以为系统架构演进临时移动用户标识(system architecture evolution temporary mobile subscription identifier,S-TMSI)，在5G系统中，该终端设备标识可以为5G系统架构演进临时移动用户标识(5G system architecture evolution temporary mobile subscription identifier,5G-S-TMSI)。

可选的，该终端设备还可以通过接入网设备以第二用户身份向第二核心网设备发送终端监听指示信息，以用于向该第二核心网设备指示终端以第一用户身份(或者说通过第一SIM卡)监听寻呼信息。例如，一种可选的方案中，该监听指示信息可以携带第一用户身份的标识，以用于指示终端监听的用户身份为第一用户身份。可以理解的是，该监听指示信息不是必须的，一种可选的方案中，通过发送第二标识信息可以隐式的指示终端监听的用户身份。
可以理解的，第二消息、寻呼冲突指示信息和监听指示信息可以是通过同一条消息发送的，例如，第二消息中携带寻呼冲突指示信息和/或监听指示信息；也可以是通过不同的消息发送，本申请并不限定。
