一种通信方法与通信装置
相关申请的交叉引用

技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法与通信装置。
背景技术
随着通信技术的发展，很多移动终端(如手机)都支持多卡功能，即一个手机中同时安装多张用户识别模块(subscriber identity module，SIM)卡，多张SIM卡可以同时在网待机。
目前，一些手机仅支持同一时刻只能从一个SIM卡接入的网络上接收信号。以双卡手机为例，当一个SIM卡进行数据传输时，另一个SIM卡无法与网络侧设备实现数据传输。例如，一个SIM卡接收下行信号，此时，若网络侧寻呼另一张SIM卡(例如该SIM卡处于空闲态)，另一张SIM卡无法监听到寻呼，导致寻呼丢失。
因此，如何改善多卡终端的寻呼机制的需要解决的问题。

需要说明的是，本申请实施例提供的通信方法可以适用于上述5G网络架构，4G网络架构或未来通信如第六代(6th generation，6G)网络架构等。当本申请实施例提供的通信方法适用于4G网络架构时，4G网络架构中的网元包括但不限定于移动管理实体(Mobility Mangement Entity，MME)，用于接入和移动管理功能。
本申请实施例中的移动性管理网元、会话管理网元、用户面网元分别可以是上述5G网络架构中的AMF、SMF、UPF，也可以是未来通信如第六代(6th generation，6G)网络中具有上述AMF、SMF、UPF的功能的网元，本申请对此不限定。为方便说明，本申请以移动性管理网元、会话管理网元、用户面网元分别为上述AMF、SMF、UPF为例进行说明。
需要说明的是，本申请实施例中，“用户身份”(例如第一用户身份或第二用户身份等)为逻辑概念。例如，“用户身份”可以对应SIM卡或签约用户信息或虚拟SIM卡或用户标识(如国际移动用户标识(international mobile subscriber identity，IMSI)或临时移动用户标识(temporary mobile subscriber identity，TMSI)等)。从网络侧的角度来看，不同的“用户身份”在逻辑上对应网络侧服务的不同通信实体，比如4G和5G系统中的UE，例如一个支持两个用户身份的终端，对于网络侧来说，可以看作两个通信实体。再例如，“用户身份”对应SIM卡或签约用户信息时，网络侧会将支持不同SIM卡或不同签约用户信息的两个终端识别为两个不同的通信实体，也会将支持多个不同SIM卡或多个签约用户信息的同一终端识别为多个不同的通信实体，即使在实际上，支持多个不同SIM卡或多个签约用户信息的终端只是一个物理实体。本申请实施例中将主要以“用户身份”对应SIM卡为例进行说明。
示例性地，SIM卡可以理解为终端接入移动网络的钥匙，为了便于描述，本申请实施例中将SIM卡以及其演进都统称为SIM卡。例如SIM卡可以是全球移动通信系统(global system for mobile communications，GSM)数字移动电话用户的身份识别卡，用于存储用户的身份识别码和密钥，并支持GSM系统对用户的鉴权；又例如，SIM卡也可以是全球用户识别卡(universal subscriber identity module，USIM)，也可以称为升级SIM卡。
需要说明的是，本申请实施例提供的通信方法适用于支持至少两个用户身份的终端。下文中，以支持两个用户身份的终端(简称双卡终端)为例进行说明。
以终端中安装有SIM卡1和SIM卡2为例。现有机制中，网络侧寻呼双卡终端内的双卡时，各自寻呼，寻呼过程不相关。对于一些双卡终端来说，SIM卡1接收下行数据时，此时，若网络侧寻呼另一张SIM卡，另一张SIM卡无法监听到寻呼，导致寻呼丢失。
基于上述技术问题，本申请实施例提供一种通信方法。该方法中，双卡终端内的一个SIM卡可以代理另一个SIM卡的寻呼。例如SIM卡1代理SIM卡2的寻呼，或者，SIM卡2代理SIM卡1的寻呼。假设SIM卡1代理SIM卡2的寻呼，若网络侧确定寻呼SIM卡2，可以通过SIM卡1寻呼SIM卡2，以避免SIM卡2寻呼丢失。
以下实施例介绍本申请实施例提供的终端的结构。
请参考图1，示出了本申请实施例提供的一种终端的结构示意图。如图1所示，终端100可以包括:第一SIM卡接口110、第二SIM卡接口120、与第一SIM卡接口110和第二SIM卡接口120分别耦合的管理器140、与管理器140耦合的处理器130，处理器130连接收发器150。其中，上述处理器130可以为基带处理器(base band processor，BBP)。如图l所示，收发器150中包括射频Rx通路和射频Tx通路。其中，上述第一SIM卡接口110用于安装SIM卡1，与SIM卡l通信，上述第二SIM卡接口120用于安装SIM卡2，与SIM卡2通信。管理器140可以向处理器130发送与SIM卡1的业务相关的上行数据包以及发送与SIM卡2的业务相关的上行数据包。处理器130可以在射频Tx通路上向网络侧设备发送SIM卡1和SIM卡2的各个上行数据包。处理器130可以在射频Rx通路上接收网络侧设备发送SIM卡1和SIM卡2的各个下行数据包。

502，网络设备1向网络设备2发送用于指示SIM卡1代理SIM卡2的寻呼的指示信息。
图5中，以SIM卡1与网络设备1协商SIM卡1代理SIM卡2的寻呼为例，所以网络设备1确定SIM卡1代理SIM卡2的寻呼之后，可以通知网络设备2SIM卡1代理SIM卡2的寻呼。示例性的，网络设备1向网络设备2发送的用于指示SIM卡1代理SIM卡2的寻呼的指示信息中还可以携带SIM卡1和SIM卡2的相关信息。
503，网络设备2确定需要寻呼SIM卡2。例如，网络设备2接收到用于寻呼SIM卡2的寻呼消息。又如，网络设备2确定有SIM卡2的下行数据待发送。具体地，网络设备2接收到来自SMF的消息，该消息用于指示有SIM卡2的下行数据待发送。
504，网络设备2向网络设备1发送第一消息，该第一消息用于指示网络设备1通过SIM卡1寻呼SIM卡2。示例性的，第一消息可以是用于指示寻呼SIM卡2或SIM卡2被寻呼的指示信息，或，用于指示网络设备1通过SIM卡1寻呼SIM卡2的指示信息，或，用于寻呼SIM卡2的寻呼消息，等等。
一种可能的实现方式为，在网络设备2确定SIM卡1代理SIM卡2的寻呼的情况下，当网络设备确定需要寻呼SIM卡2时，立即执行504。
另一张可能的实现方式为，当网络设备2确定需要寻呼SIM卡2时，可以先通过SIM卡2寻呼，当寻呼失败之后，再执行504。
又一种可能的实现方式为，在网络设备2确定SIM卡1代理SIM卡2的寻呼的情况下，当网络设备确定需要寻呼SIM卡2时，若确定SIM卡2处于非激活态或空闲态，再执行504。

在一些实施例中，当网络设备2向网络设备1发送第一消息之后，若网络设备1确定SIM卡1无法代理SIM卡2的寻呼时，可以向网络设备2发送第三消息，该第三消息用于指示网络设备1拒绝通过所述SIM卡1寻呼SIM卡2。其中，SIM卡1无法代理SIM卡2的寻呼的情况有多种，例如，SIM卡1当前处于空闲态或非激活态。应理解，第三消息中还可以携带网络设备1拒绝通过所述SIM卡1寻呼SIM卡2的理由，例如携带有用于指示SIM卡1当前处于空闲态的指示信息。
505，网络设备1通过SIM卡1寻呼SIM卡2。
本申请实施例中，网络设备1通过SIM卡1寻呼SIM卡2，可以理解为网络设备1通过SIM卡1指示SIM卡2被寻呼。例如，网络设备1向SIM卡1发送用户寻呼SIM卡2的寻呼消息，或者，网络设备1向SIM卡1发送用于指示SIM卡2被寻呼的指示信息，等等。
示例性的，网络设备1通过SIM卡1寻呼SIM卡2的方式有多种，包括但不限定如下的两种方式。

方式2，网络设备1向网络设备3发送第五消息，该第五消息用于寻呼SIM卡2。网络设备3向SIM卡1发送将该第六消息，该第六消息用于寻呼SIM卡2。其中，网络设备3例如为SIM卡1的服务基站。其中，第五消息用于寻呼所SIM卡2，也可以理解为第五消息用于指示SIM卡2被寻呼。第六消息用于寻呼所SIM卡2，也可以理解为第六消息用于指示SIM卡2被寻呼。
需要说明的是，假设终端与网络侧协商SIM卡1代理SIM卡2的寻呼，则终端可以通过SIM卡1监听SIM卡2的寻呼。例如，当SIM卡1占用该射频Rx通路接收下行信号时，终端可以通过该SIM卡1监听SIM卡2的寻呼，不会导致SIM卡2的寻呼丢失。举例来说，终端的两个SIM卡在寻呼时机(paging occasion，PO)在时间上重叠，当两个SIM卡都处于空闲态时，终端可以在一个SIM卡的PO上监听另一个SIM卡的寻呼，不会丢失另一个SIM卡的寻呼。
506，SIM卡1向SIM卡2指示SIM卡2被寻呼。

需要说明的是，图4或图5所示的实施例中的网络设备1可以是第一通信系统下的装置，网络设备2可以是第二通信系统下的装置，其中，第一通信系统为LTE系统、EPC系统或5G系统，第二通信系统为LTE系统、EPC系统或5G系统，等等。示例性的，假设网络设备1和网络设备2均是5G系统下的装置，网络设备1可以是接入与第一移动性管理功能AMF、第一会话管理功能SMF、第一无线接入网RAN或第一用户面功能UPF；网络设备2可以是所述第二通信装置为第二AMF、第二SMF、第二RAN或第二用户面功能UPF。假设网络设备1和网络设备2均是4G系统下的装置，例如，网络设备1可以是第一MME，网络设备2可以是第二MME。当然，网络设备1可以是5G系统下的第一AMF、第一SMF或第一UPF；网络设备2可以是4G系统下的第二MME。或者，网络设备1可以是4G系统下的第二MME；网络设备2可以是5G系统下的第二AMF、第二SMF或第二UPF。
以下实施例以网络设备1和网络设备2均是5G系统下的装置为例介绍，且以终端与核心网设备协商SIM卡1代理SIM卡2的寻呼为例。
实施例1，SIM卡2处于空闲态，SIM卡1的状态不作限定。
参见图6，SIM卡2接入核心网后，与核心网中与SIM卡2相关的核心网设备(例如，AMF、SMF、UPF)通信。SIM卡2接入核心网后，与核心网中与SIM卡1相关的核心网 设备(例如，AMF、SMF、UPF)通信。
SIM卡2对应的UPF接收到用于寻呼SIM卡2的寻呼消息后，将该寻呼消息发送给SMF。SMF将寻呼消息发送卡2对应的AMF。SIM卡2对应的AMF确定SIM卡2处于空闲态时，向SIM卡1对应的AMF发送第一消息，该第一消息用于指示SIM卡1对应的AMF通过SIM卡1寻呼SIM卡2。SIM卡1的AMF接收到第一消息之后，可以向SIM卡2的AMF发送第二消息，该第二消息用于指示SIM卡1对应的AMF通过SIM卡1寻呼SIM卡2。SIM卡1的AMF通过SIM卡1对应的gNB向SIM卡1发送所述寻呼消息。SIM卡1将该寻呼消息发送给SIM卡2。
在该实施例中，在SIM卡1代理SIM卡2的寻呼的情况下，当SIM卡2的网络设备接收到用于寻呼SIM卡2的寻呼消息之后，若确定SIM卡2处于空闲态，则通过SIM卡1代理SIM卡2的寻呼，无需考虑SIM卡1当前的状态。
实施例2，SIM卡2处于非激活态，SIM卡1的状态不作限定，例如，SIM卡1可以处于非激活态或连接态。
参见图7，当SIM卡2对应的UPF接收到寻呼消息，将该寻呼消息发送给SMF。SMF将寻呼消息发送SIM卡2对应的AMF。SIM卡2对应的AMF确定SIM卡2处于非激活态后，向SIM卡1对应的AMF发送第一消息，该第一消息用于指示SIM卡1对应的AMF通过SIM卡1寻呼SIM卡2。SIM卡1的AMF接收到第一消息之后，可以向SIM卡2的AMF发送第二消息，该第二消息用于指示通过SIM卡1寻呼SIM卡2。SIM卡1的AMF通过SIM卡1的gNB向SIM卡1发送所述寻呼消息。SIM卡1将该寻呼消息发送给SIM卡2。
其中，SIM卡2对应的AMF确定SIM卡2处于非激活态的方式可以是，SIM卡2对应的AMF向SIM卡2对应的gNB发送状态查询消息，该状态查询消息用于查询SIM卡2当前的状态。gNB向AMF反馈用于指示SIM卡2当前的状态(例如，非激活态)的消息。
在该实施例中，SIM卡2对应的网络设备确定SIM卡2处于非激活态时，通过SIM卡1寻呼SIM卡2，可以无需考虑SIM卡1当前的状态。
实施例2与实施例1的区别在于，实施例1中SIM卡2处于空闲态时，SIM卡2对应的AMF可以确定SIM卡1当前处于空闲态，无需通过SIM卡2对应的gNB查询SIM卡2的当前状态。实施例2中，SIM卡2处于非激活态时，SIM卡2对应的AMF需要通过SIM卡2对应的gNB查询SIM卡2的当前状态。
实施例3，SIM卡2处于空闲态时，若SIM卡1处于非激活态或连接态，则SIM卡1代理SIM卡2的寻呼。
参见图8，当SIM卡2对应的UPF接收到寻呼消息，将该寻呼消息发送给SMF。SMF将寻呼消息发送SIM卡2对应的AMF。SIM卡2对应的AMF确定SIM卡2处于空闲态时，向SIM卡1对应的AMF发送第一消息，该第一消息用于指示SIM卡1对应的AMF通过SIM卡1寻呼SIM卡2。SIM卡1的AMF接收到第一消息之后，可以判断SIM卡1当前处于何种状态，若SIM卡1当前处于连接态或非激活态，则SIM卡1的AMF可以向SIM卡2的AMF发送第二消息，该第二消息用于指示通过SIM卡1寻呼SIM卡2。SIM卡1的AMF通过SIM卡1的gNB向SIM卡1发送所述寻呼消息。SIM卡1将该寻呼消息发送给SIM卡2。
其中，SIM卡1的AMF判断SIM卡1当前处于何种状态可以包括，SIM卡1对应的 AMF向SIM卡1对应的gNB发送状态查询消息，该状态查询消息用于查询SIM卡1当前的状态。gNB向AMF反馈用于指示SIM卡1当前状态(例如非激活态或连接态)的消息。
可以理解的是，假设SIM卡1的AMF接收到第一消息之后，判断SIM卡1当前处于空闲态，可以向SIM卡2对应的AMF发送拒绝消息，该拒绝消息用于指示拒绝通过SIM卡1寻呼SIM卡2。示例性的，该拒绝消息中还可以携带拒绝理由，例如携带有用于指示SIM卡1处于空闲态的指示信息。
区别于实施例1和实施例2，在该实施例中，处于非激活态或连接态的SIM卡可以代理处于空闲态的SIM卡的寻呼。
实施例4，SIM卡2处于非激活态时，若SIM卡1处于连接态，则SIM卡1代理SIM卡2的寻呼。
参见图9，当SIM卡2对应的UPF接收到寻呼消息，将该寻呼消息发送给SMF。SMF将寻呼消息发送SIM卡2对应的AMF。SIM卡2对应的AMF确定SIM卡2处于非激活态(例如通过SIM卡2对应的gNb查询SIM卡2当前处于非激活态)，向SIM卡1对应的AMF发送第一消息，该第一消息用于指示SIM卡1对应的ANF通过SIM卡1寻呼SIM卡2。SIM卡1的AMF接收到第一消息后，可以判断SIM卡1当前处于何种状态，若确定SIM卡1当前处于连接态，则向SIM卡2的AMF发送第二消息，该第二消息用于指示确认通过SIM卡1寻呼SIM卡2。SIM卡1的AMF通过SIM卡1的gNB向SIM卡1发送所述寻呼消息。SIM卡1将该寻呼消息发送给SIM卡2。

区别于上述其它实施例，在该实施例中，处于连接态的SIM卡可以代理处于空闲态的SIM卡的寻呼。

当通信装置是终端时，图16示出了一种简化的终端的结构示意图。便于理解和图示方便，图16中，终端以手机作为例子。如图16所示，终端包括处理器、存储器、射频电路、天线以及输入输出装置。处理器主要用于对通信协议以及通信数据进行处理，以及对终端进行控制，执行软件程序，处理软件程序的数据等。存储器主要用于存储软件程序和数据。射频电路主要用于基带信号与射频信号的转换以及对射频信号的处理。天线主要用于收发电磁波形式的射频信号。输入输出装置，例如触摸屏、显示屏，键盘等主要用于接收用户输入的数据以及对用户输出数据。需要说明的是，有些种类的终端可以不具有输入输出装置。
当需要发送数据时，处理器对待发送的数据进行基带处理后，输出基带信号至射频电路，射频电路将基带信号进行射频处理后将射频信号通过天线以电磁波的形式向外发送。当有数据发送到终端时，射频电路通过天线接收到射频信号，将射频信号转换为基带信号，并将基带信号输出至处理器，处理器将基带信号转换为数据并对该数据进行处理。为便于说明，图16中仅示出了一个存储器和处理器。在实际的终端产品中，可以存在一个或多个处理器和一个或多个存储器。存储器也可以称为存储介质或者存储设备等。存储器可以是独立于处理器设置，也可以是与处理器集成在一起，本申请实施例对此不做限制。
在本申请实施例中，可以将具有收发功能的天线和射频电路视为终端的收发单元，将 具有处理功能的处理器视为终端的处理单元。如图16所示，终端包括收发单元1610和处理单元1620。收发单元也可以称为收发器、收发机、收发装置等。处理单元也可以称为处理器，处理单板，处理模块、处理装置等。可选的，可以将收发单元1610中用于实现接收功能的器件视为接收单元，将收发单元1610中用于实现发送功能的器件视为发送单元，即收发单元1610包括接收单元和发送单元。收发单元有时也可以称为收发机、收发器、或收发电路等。接收单元有时也可以称为接收机、接收器、或接收电路等。发送单元有时也可以称为发射机、发射器或者发射电路等。
应理解，收发单元1610用于执行上述方法实施例中终端侧的发送操作和接收操作，处理单元1620用于执行上述方法实施例中终端上除了收发操作之外的其他操作。
例如，在一种实现方式中，收发单元1610用于执行图5中步骤501、步骤505、506、507等。当然，收发单元1610还用于执行本申请实施例中终端侧的其他收发步骤。处理单元1620用于执行图5中终端的处理步骤，例如，确定哪个SIM卡代理另一个SIM卡的寻呼。
