背景技术
目前，第五代移动通信技术(5th generation，5G)新空口(new radio，NR)系统中引入了一种新的无线资源控制(radio resource control，RRC)连接状态，RRC非激活态(也称为RRC_INACTIVE)。在RRC非激活态下，当网络侧有业务到达时，数据或信令会直接到达接入网设备，进而触发接入网设备对终端设备进行寻呼。
现有技术中，接入网设备寻呼处于RRC非激活态的终端设备时，寻呼消息中无法携带寻呼的原因值。这使得终端设备无法根据寻呼的原因值，决定是否响应接收到的寻呼消息。对于包括两个用户身份识别(subscriber identification module，SIM)卡，但仅具有单一发送能力的终端设备来说，寻呼消息中不包括寻呼的原因值，可能会使得某一SIM卡上的低优先级业务对另一SIM卡上的高优先级业务造成影响。例如，终端设备正在进行某一SIM卡上的业务，此时接收到接入网设备针对另一SIM卡的寻呼消息，寻呼消息中不包括寻呼的原因值，可能导致终端设备无法及时响应该另一SIM卡上的高优先级业务。

还应理解，本申请实施例中的术语“系统”和“网络”可被互换使用。“多个”是指两个或两个以上，鉴于此，本申请实施例中也可以将“多个”理解为“至少两个”。“至少一个”，可理解为一个或多个，例如理解为一个、两个或更多个。例如，包括至少一个，是指包括一个、两个或更多个，而且不限制包括的是哪几个。例如，包括A、B和C中的至少一个，那么包括的可以是A、B、C，A和B，A和C，B和C，或A和B和C。同理，对于“至少一种”等描述的理解，也是类似的。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，字符“/”，如无特殊说明，一般表示前后关联对象是一种“或”的关系。
除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度，并且“第一”、“第二”的描述也并不限定对象一定不同。
请参考图2，为本申请实施例提供的一种通信方法的流程示意图，该方法可包括如下的步骤S201至步骤S206：
步骤S201、第一核心网设备生成第一信息，该第一信息用于指示第一业务的业务类型和/或业务优先级。
第一核心网设备可在确定第一终端设备的第一业务到达核心网时或到达核心网之后，生成该第一信息，所述第一业务到达核心网可以为到达第一核心网设备或第二核心网设备。该第一业务为第一终端设备的业务，且该第一终端设备当前处于RRC非激活态。例如，第一业务可以为第一终端设备的语音业务、视频业务、多媒体业务、数据业务等等。应理解，本申请实施例对涉及到的终端设备的业务的业务类型不作具体限定，第一业务也可以 是其他类型的业务，后面提及的第二业务与此类似。
具体的，第一信息可包含在第一消息中，该第一消息可用于指示第一接入网设备寻呼第一终端设备。也就是说，第一核心网设备在生成第一信息后，可将该第一信息携带在第一消息中发送给第一接入网设备。即步骤S202也可以为，第一核心网设备向第一接入网设备发送第一消息，该第一消息中包括第一信息。该第一消息中还可包括用于指示第一业务的非接入层(non-access stratum，NAS)信息。该第一消息可以称为第一寻呼指示消息，或者也可以具有其他名称，本申请并不限定。
在一种可能的设计中，第一核心网设备可以为AMF。
步骤S202、第一核心网设备向第一接入网设备发送第一信息，该第一接入网设备为第一终端设备的锚点(Anchor)接入网设备。
所述锚点接入网设备是指，第一终端设备在进入RRC连接态之前接入的接入网设备。本申请实施例中，第一终端设备在进入RRC非激活态之前处于RRC连接态。因此，锚点接入网设备也可以理解为，第一终端设备在最近一次处于RRC连接态时接入的接入网设备。例如，若接入网设备为基站，该第一接入网设备可以为第一终端设备的锚点基站。
步骤S203、第一接入网设备从第一核心网设备接收第一信息。
步骤S204、第一接入网设备向第一终端设备发送第一寻呼消息，该第一寻呼消息中包括第一业务的业务类型和/或业务优先级。
需要说明的是，在第一终端设备最近一次从RRC连接态转换到RRC非激活态时，第一接入网设备还可向第一终端设备发送RRC连接释放消息或RRC连接暂停消息，该RRC连接释放消息或RRC连接暂停消息中可包括用于指示第一RNA区域的信息。该第一RNA区域用于支持第一终端设备在RRC非激活态下的移动性，第一RNA区域具体可以为第一无线接入网通知区域(RAN-based notification area，RNA)区域。当第一终端设备进入RRC非激活态后，第一终端设备在该第一RNA区域内移动发生小区重选时，可继续使用保留的传输资源或传输资源池。
考虑到第一终端设备当前处于RRC非激活态，第一接入网设备还可向第二接入网设备发送第二消息，该第二消息中包括用于指示第一业务的业务类型和/或业务优先级的信息，例如可以是第一信息。该第二消息用于指示第二接入网设备向第一终端设备发送第二寻呼消息，该第二寻呼消息中包括用于指示第一业务的业务类型和/或业务优先级的信息，例如也可以是第一信息。该第二消息可以称为第二寻呼指示消息，或者也可以具有其他名称，本申请并不限定。应理解，第二接入网设备与第一接入网设备位于同一RNA区域。即第二接入网设备可以为第一终端设备对应的第一RNA区域中除第一接入网设备之外的其他接入网设备。
本申请实施例中，第二接入网设备可以为一个或多个。也就是说，第一接入网设备在从第一核心网设备接收到第一消息后，可向第一RNA区域内的一个或多个其他接入网设备发送第二消息，该第二消息中包括用于指示第一业务的业务类型和/或业务优先级的第一信息，以使第一RNA区域内的其他接入网设备向第一终端设备发送寻呼消息，并在寻呼消息中携带第一业务的业务类型和/或业务优先级。可选的，第一接入网设备可向第一终端设备对应的第一RNA区域内的所有其它接入网设备均发送该第二消息，以使该RNA区域内的所有接入网设备可向第一终端设备发送寻呼消息，并在寻呼消息中携带第一业务的业务类型和/或业务优先级。
步骤S205、第一终端设备从第一接入网设备接收第一寻呼消息。进一步，该第一终端设备处于RRC非激活态。
本申请实施例中，第一终端设备还可从第二接入网设备接收第二寻呼消息。可以理解，由于第一终端设备对应的第一RNA区域内的一个或多个接入网设备均可向第一终端设备发送寻呼消息，因此，第一终端设备实际接收到的寻呼消息，可以是第一接入网设备发送的第一寻呼消息，也可以是第二接入网设备发送的第二寻呼消息(即第一RNA区域内的其他接入网设备发送的寻呼消息)。而且第一寻呼消息和第二寻呼消息中均包括用于指示第一业务的业务类型和/或业务优先级的信息，例如可以是第一信息。
步骤S206、第一终端设备根据第一业务的业务类型和/或业务优先级，确定是否处理第一业务。
本申请实施例中，该第一业务的业务类型和/或业务优先级可以理解为接入网设备寻呼第一终端设备的寻呼的原因值，第一终端设备可根据寻呼的原因值，确定是否处理该第一业务。例如，若第一终端设备当前没有在进行其他业务，第一终端设备可直接确定需处理该第一业务。若第一终端设备当前正在进行其他业务，例如可以是第二业务，第一终端设备可根据第一业务的业务类型和/或业务优先级、以及正在进行的第二业务的业务类型和/或业务优先级，确定是否需要处理该第一业务。所述第一终端设备确定是否处理第一业务，可以理解为第一终端设备确定是否接纳该第一业务，第一终端设备确定接纳该第一业务后，可与第一接入网设备或第二接入网设备建立RRC连接，并从第一接入网设备或第二接入网设备接收该第一业务的数据。
在一种可能的设计中，该第一终端设备可具有两个标识，分别为第一标识和第二标识，其中，第一业务可与第一终端设备的第一标识关联，第二业务可与第一终端设备的第二标识关联。如此，所述第一终端设备处于RRC非激活态是指，第一终端设备与第一标识关联的RRC状态为RRC非激活态，第一接入网设备是指第一终端设备的第一标识最近一次关联的RRC状态为RRC连接态时接入的接入网设备，第二接入网设备是指第一终端设备的第一标识对应的第一RNA区域中除第一接入网设备之外的其他接入网设备。第一终端设备当前正在进行第二业务，可表示第一终端设备与第二标识关联的RRC状态为RRC连接态。此外，考虑到第一核心网设备确定第一终端设备的第一标识关联的第一业务到达后，会触发第一接入网设备发送第一寻呼消息以及第二接入网设备发送第二寻呼消息，因此该第一寻呼消息和第二寻呼消息中除了该第一业务的业务类型和/或业务优先级之外，还可包括第一业务关联的第一标识，表示第一寻呼消息和第二寻呼消息是针对第一终端设备的第一标识的寻呼。
也就是说，第一终端设备可以为支持双卡双待的终端设备，第一终端设备中可包括两个SIM卡，其中，SIM卡1与第一标识对应，SIM卡2与第二标识对应，第一业务可以为第一终端设备的SIM卡1上的业务，第二业务可为第一终端设备的SIM卡2上的业务。如此，所述第一终端设备处于RRC非激活态是指，第一终端设备的SIM卡1当前处于RRC非激活态，即第一终端设备与第一标识关联的RRC状态为第一终端设备中的SIM卡1对应的RRC状态。第一接入网设备是指第一终端设备的SIM卡1最近一次处于RRC连接态时接入的接入网设备，第二接入网设备是指第一终端设备的SIM卡1对应的第一RNA区域中除第一接入网设备之外的其他接入网设备。第一终端设备当前正在进行第二业务，可表示第一终端设备的SIM卡2当前处于RRC连接态，即第一终端设备与第二标识关联的 RRC状态为第一终端设备中的SIM卡2对应的RRC状态。此外，第一接入网设备发送的第一寻呼消息中，以及第二接入网设备发送的第二寻呼消息中除第一业务的业务类型和/或业务优先级之外，还可包括第一终端设备的第一标识，表示第一寻呼消息和第二寻呼消息是针对第一终端设备的SIM卡1的寻呼。
具体的，所述第一标识和第二标识，可以指核心网为第一终端设备的SIM卡1和SIM卡2分配的标识，例如临时移动台标识(temporary mobile subscriber identity，TMSI)或5G网络临时移动台标识(5G temporary mobile subscriber identity，5G-TMSI)，或国际移动用户识别码(international mobile subscriber identity，IMSI)。所述第一标识和第二标识，也可以指接入网为第一终端设备的SIM卡1和SIM卡2分配的标识，例如小区无线网络临时标识(cell radio network temporary identifier，C-RNTI)。
具体的，第一终端设备当前正在进行第二业务，第一终端设备接收到第一寻呼消息或第二寻呼消息之后，若确定第一业务的业务优先级高于第二业务的业务优先级，那么第一终端设备可确定需要处理第一业务，并暂停第二业务。或者，第一终端设备接收到第一寻呼消息或第二寻呼消息之后，可发出提示信息，该提示信息用于指示第一业务的业务类型。随后，第一终端设备可获取用户针对该提示信息的响应信息，并根据该响应信息确定是否处理该第一业务。若用户通过响应信息指示处理该第一业务，则第一终端设备可确定需要处理该第一业务，并暂停第二业务。若用户通过响应信息指示不处理该第一业务，或者第一终端设备在设定的时间段内未获取到针对提示信息的响应信息，则第一终端设备可确定不处理该第一业务。例如，第一终端设备可在显示屏幕上向用户显示新到达的第一业务的业务类型，并在显示屏幕上设置两个按钮，分别对应“是”、“否”两个选项，由用户手动选择是否处理该第一业务。
本申请实施例中，第一终端设备确定需要处理第一业务后，还需要响应接收到的寻呼消息。具体的，若第一终端设备接收到的是第一接入网设备发送的第一寻呼消息，第一终端设备在确定需要处理第一业务后，可向第一接入网设备发起随机接入过程，以接入网络响应寻呼。进而，第一接入网设备可与第一终端设备建立RRC连接，并在与第一终端设备建立RRC连接后，向第一终端设备发送用于指示第一业务的NAS信息。后续，第一接入网设备还可向第一终端设备发送第一业务的数据。
若第一终端设备接收到的是第二接入网设备发送的第二寻呼消息，第一终端设备在确定需要处理第一业务后，可向第二接入网设备发起随机接入过程，以接入网络响应寻呼。第一接入网设备还可向第二接入网设备发送用于指示第一业务的NAS信息，第二接入网设备可在与第一终端设备建立RRC连接后，将该NAS信息发送给第一终端设备。后续，第二接入网设备还可向第一终端设备发送第一业务的数据。

本申请实施例中，第一终端设备具有两个标识，分别为第一标识和第二标识。可以理解为，第一终端设备为支持双卡双待功能的终端设备，该终端设备中包括两个SIM卡，其中，SIM卡1与第一标识对应，SIM卡2与第二标识对应。相应地，第一终端设备可具有两个RRC状态，一个RRC状态与第一终端设备的第一标识关联，是指SIM卡1的RRC状态，另一个RRC状态与第一终端设备的第二标识关联，是指SIM卡2的RRC状态。由于第一终端设备发送的传输暂停请求信息用于请求暂停与第二标识关联的第二业务，因此，可以理解当前第一终端设备与第二标识关联的RRC状态可以为RRC连接态，即SIM卡2处于RRC连接态，而第一终端设备与第一标识关联的RRC状态可以为RRC非激活态，即SIM卡1可以处于RRC非激活态。
具体的，所述第一标识和第二标识，可以指核心网为第一终端设备的SIM卡1和SIM卡2分配的标识，例如临时移动台标识(temporary mobile subscriber identity，TMSI)或5G网络临时移动台标识(5G temporary mobile subscriber identity，5G-TMSI)，或国际移动用户识别码(international mobile subscriber identity，IMSI)。所述第一标识和第二标识，也可以指接入网为第一终端设备的SIM卡1和SIM卡2分配的标识，例如小区无线网络临时标识(cell radio network temporary identifier，C-RNTI)。

此外，第一核心网设备还可向第二核心网设备发送第二指示信息，该第二指示信息用于指示该第二核心网设备停止向第三接入网设备发送第二业务的数据。如此，第二核心网设备接收到该第二指示信息后，可停止向第三接入网设备发送第二指示信息，从而在网络侧暂停了该第二业务。在一种可能的设计中，第二核心网设备可以为UPF。
步骤S304、第一核心网设备向第一终端设备发送传输暂停响应信息，该传输暂停响应信息中包括第二标识，该传输暂停响应信息用于向第一终端设备指示已暂停该第二业务。可选地，第一核心网设备可在接收到第一终端设备发送的传输暂停请求信息后，向第一终端设备发送传输暂停响应信息。或者，第一核心网设备也可以在向第三接入网设备发送第 一指示信息和/或向第二核心网设备发送第二指示信息之后，向第一终端设备发送传输暂停响应信息，本申请并不限定。
步骤S305、第一终端设备接收第一核心网设备发送的传输暂停响应信息。
本申请实施例中，第一终端设备可在确定需要暂停第二业务时，向第一核心网设备发送传输暂停请求信息。需要暂停第二业务可能是因为，第一终端设备为具有单一发送能力的终端设备，在处理第二业务的过程中，第一终端设备接收到了来自第一接入网设备的第一寻呼消息或者来自第二接入网设备的第二寻呼消息，该第一寻呼消息或第二寻呼消息为针对第一终端设备的第一标识的寻呼，即针对第一终端设备中的SIM卡1的寻呼。而且该第一寻呼消息和第二寻呼消息中指示的第一业务的业务优先级高于该第二业务的业务优先级，或者第一终端设备在接收到第一寻呼消息或第二寻呼消息后，获取到了用户确定处理该第一业务的响应信息。
可选的，第一终端设备在暂停第二业务后，还可恢复该第二业务。例如，第三接入网设备可向第一核心网设备发送传输恢复请求信息，该传输恢复请求信息中包括第二标识，用于请求恢复与第二标识关联的第二业务。第一核心网设备接收到该传输恢复请求信息后，可向第二核心网设备发送第五指示信息，该第五指示信息用于指示第二核心网设备恢复向该第三接入网设备发送第二业务的数据。第一核心网设备还可向第三接入网设备发送传输恢复响应信息，第一核心网设备可在接收到传输恢复请求信息之后，向第三接入网设备发送传输恢复响应信息，也可以在向第二核心网设备发送第五指示信息之后，向第三接入网设备发送传输恢复响应信息，本申请并不限定。此外，第三接入网设备接收到传输恢复响应信息之后，还可向第一终端设备发送RRC连接建立消息或RRC连接恢复消息，以将第一终端设备与第二标识关联的RRC状态转换至RRC连接态。
请参考图4，为本申请实施例提供的又一种通信方法的流程示意图，该方法可包括如下的步骤S401至步骤S406：
步骤S401、第一终端设备向第一核心网设备发送第三指示信息，该第三指示信息用于指示第一终端设备的第一标识和第二标识。
本申请实施例中，第一终端设备为支持双卡双待功能的终端设备，该终端设备中包括两个SIM卡，SIM卡1与第一标识对应，SIM卡2与第二标识对应。相应地，第一终端设备可具有两个RRC状态，一个RRC状态与第一终端设备的第一标识关联，是指SIM卡1的RRC状态，另一个RRC状态与第一终端设备的第二标识关联，是指SIM卡2的RRC状态。通过向第一核心网设备发送第一标识和第二标识，第一核心网设备可确认第一标识和第二标识实际上是同一终端设备实体的标识，即SIM卡1和SIM卡2均为第一终端设备中的SIM卡，于是，第一核心网设备可从网络侧将SIM卡1与SIM卡2绑定或关联。
具体的，所述第一标识和第二标识，可以指核心网为第一终端设备的SIM卡1和SIM卡2分配的标识，例如临时移动台标识(temporary mobile subscriber identity，TMSI)或5G网络临时移动台标识(5G temporary mobile subscriber identity，5G-TMSI)，或国际移动用户识别码(international mobile subscriber identity，IMSI)。所述第一标识和第二标识，也可以指接入网为第一终端设备的SIM卡1和SIM卡2分配的标识，例如小区无线网络临时标识(cell radio network temporary identifier，C-RNTI)。
进一步地，该第一终端设备还可以是具有单一发送能力的终端设备，如此，第三指示 信息中还可包括第一终端设备的能力信息，该能力信息用于指示第一终端设备的发送能力为单一发送，从而使得第一核心网设备可根据第一终端设备的第一标识和第二标识，结合第一终端设备的单一发送能力，从网络侧决定是否处理某一标识关联的业务。

步骤S403、第一核心网设备确定第一终端设备的第一业务到达，该第一业务与第一终端设备的第一标识关联，第一终端设备与第一标识关联的RRC状态为RRC非激活态或RRC空闲态。
第一业务与第一终端设备的第一标识关联，可以理解为第一业务是第一终端设备的SIM卡1的业务。第一终端设备当前与第一标识关联的RRC状态为RRC非激活态或RRC空闲态可以理解为，第一终端设备的SIM卡1当前处于RRC非激活态或RRC空闲态。
步骤S404、第一核心网设备根据第一业务的业务类型或业务优先级、以及第二业务的业务类型或业务优先级，确定是否处理第一业务。
在一种可能的设计中，若第一业务的业务优先级高于第二业务的业务优先级，第一核心网设备可确定处理第一业务，并暂停第二业务。本申请实施例中，第一核心网设备中可以预先存储有各个业务类型的业务优先级。或者，第一核心网设备也可以从第一终端设备接收业务优先级信息，该业务优先级信息中包括第一终端设备的至少一种业务类型的业务的业务优先级，如此可使不同的终端设备为各种业务类型的业务设置的业务优先级不同，从而有效提高业务处理的灵活性，提高用户体验。
若第一核心网设备确定处理第一业务，第一核心网设备可触发针对第一终端设备的第一标识的寻呼，并暂停第一终端设备与第二标识的关联的第一业务，将第一终端设备与第二标识关联的RRC状态释放至RRC非激活态或RRC空闲态。
具体的，在步骤S405中，第一核心网设备可向接入网设备发送第四指示信息，该第四指示信息用于指示接入网设备针对第一终端设备的第一标识进行寻呼，即寻呼第一终端设备的SIM卡1。接入网设备接收到该第四指示信息后，在步骤S406中，可携带第一终端设备的第一标识向该第一终端设备发送寻呼消息。第一终端设备响应该寻呼消息，并与接入网设备建立RRC连接后，第一终端设备与第一标识关联的RRC状态可由RRC非激活态转换至RRC连接态，即第一终端设备的SIM卡1进入RRC连接态。后续，第一终端设备还可从接入网设备接收第一业务的数据。可以理解，本申请实施例中，第一终端设备可通过第一标识(即对应SIM卡1的标识)和第二标识(即对应SIM卡2的标识)连接到同一接入网设备。
在步骤S407中，第一核心网设备还可向接入网设备发送第一指示信息，该第一指示 信息用于指示接入网设备将第一终端设备与第二标识关联的RRC状态由RRC连接态释放至RRC空闲态或RRC非激活态。接入网设备接收到该第一指示信息后，在步骤S408中，可携带第一终端设备的第二标识，向该第一终端设备发送RRC连接释放消息或RRC连接暂停消息。此外，第一核心网设备还可向第二核心网设备发送第二指示信息，该第二指示信息用于指示第二核心网设备停止向接入网设备发送第二业务的数据。在一种可能的设计中，该第二核心网设备可以为UPF。
