Description

一种通信方法及设备 技术领域
本发明实施例涉及通信技术领域，尤其涉及一种通信方法及设备。
背景技术
在终端设备设置有两个接收机和一个发射机的情况下，终端设备支持两个全球用户身份识别(universal subscriber identification module，USIM)，当两个USIM均处于空闲态时，两个USIM都可以接收网络寻呼。当有一个USIM处于连接态时，另一个USIM可以使用另一个接收机接收网络寻呼。
然而，当有一个USIM处于连接态时，接收到针对另一个USIM的寻呼消息之后，在终端设备响应该寻呼消息的情况下，这个USIM的业务数据会被挂起，在终端设备不响应该寻呼消息的情况下，该寻呼消息对应的业务会被拒绝。因此，终端设备如何确定是否响应寻呼消息已成为一个亟待解决的技术问题。
发明内容
本发明实施例公开了一种通信方法及设备，用于根据寻呼消息携带的业务的业务信息确定是否响应寻呼消息。
第一方面公开一种通信方法，终端设备接收来自接入与移动性管理功能(access and mobility managementfunction，AMF)网元的携带第一业务的第一业务信息的寻呼消息，根据第一业务的第一业务信息和第二业务的业务信息向AMF网元发送该寻呼消息的响应消息。该寻呼消息对应终端设备的至少两个USIM中的第一USIM，第二业务为终端设备的第二USIM的当前业务，第二USIM处于连接态。可见，终端设备可以根据寻呼消息携带的业务的业务信息和终端设备上当前处于连接态的USIM的业务的业务信息确定是否响应寻呼消息，而不是盲目的响应寻呼消息，从而可以避免一旦接收到寻呼消息就挂起终端设备上当前处于连接态的USIM的业务。
作为一种可能的实施方式，第一业务的第一业务信息可以包括第一业务的优先级，也可以包括第一业务的业务类型信息，还可以包括第一业务的5G服务质量(quality of service，QoS)流(flow)标识(5G QoS identifier，5QI)、差分服务代码点(differentiated services code point，DSCP)和QoS流标识(QoS flow identifier，QFI)中的至少一种。
作为一种可能的实施方式，当终端设备根据第一业务的第一业务信息和第二业务的业务信息确定第一业务的优先级高于第二业务的优先级时，终端设备向AMF网元发送寻呼消息的响应消息。可见，在终端设备接收的寻呼消息携带的业务的优先级高于终端设备上当前处于连接态的USIM的业务的优先级的情况下，才响应寻呼消息，可以保证先处理优先级高的业务，从而可以保证重要的业务先处理。
作为一种可能的实施方式，当第一业务的第一业务信息不包括第一业务的优先级，且第二业务的业务信息包括第二业务的优先级时，终端设备可以先根据第一业务的第一业务信息获得第一业务的优先级，之后再确定第一业务的优先级高于第二业务的优先级。
作为一种可能的实施方式，在第一业务的第一业务信息包括第一业务的5QI、DSCP和QFI中的至少一种的情况下，终端设备可以先根据第一业务的第一业务信息获得第一业务的业务类型信息，之后再根据第一业务的业务类型信息获得第一业务的优先级。
作为一种可能的实施方式，终端设备可以向AMF网元发送用于指示向终端设备发送的寻呼消息中携带业务的业务信息指示信息，以便终端设备可以根据寻呼消息携带的业务的业务信息确定是否响应寻呼消息。终端设备也可以向AMF网元发送终端设备的用于指示终端设备支持至少两个USIM的USIM能力信息，以便AMF网元可以根据USIM能力信息在寻呼消息中携带业务的业务信息。
第二方面公开一种通信方法，终端设备可以向AMF网元发送终端设备的用于指示业务的优先级的业务优先级信息，以便AMF网元可以根据业务的业务优先级信息确定是否要在寻呼消息中携带业务的业务信息。
作为一种可能的实施方式，终端设备可以向AMF网元发送第二业务的业务信息，第二业务为终端设备的至少两个USIM中第二USIM的当前业务，第二USIM处于连接态，以便AMF网元可以根据业务的业务优先级信息以及终端设备上当前处于连接态的USIM的业务的业务信息确定是否发送寻呼消息以及是否要在寻呼消息中携带业务的业务信息。
作为一种可能的实施方式，在该当前业务包括至少两个业务的情况下，第二业务为可以至少两个业务中优先级最高的业务，可以在不影响上报信息作用的情况下可以减少上报的信息量。
作为一种可能的实施方式，终端设备可以向AMF网元发送用于指示不向第一USIM发送寻呼消息的免寻呼指示，以便AMF网元可以根据免寻呼指示不向终端设备的第一USIM发送寻呼消息，可以减少消息数量，从而可以节约传输资源。第一USIM为终端设备的至少两个USIM中处于空闲态的任一USIM。
作为一种可能的实施方式，免寻呼指示可以携带第一USIM的标识，以便可以根据该标识确定不向那个USIM发送寻呼消息。
作为一种可能的实施方式，当第二业务在终端设备支持的业务中优先级最高时，终端设备向AMF网元发送免寻呼指示，第二业务为终端设备的至少两个USIM中第二USIM的当前业务，第二USIM处于连接态。可见，在终端设备上当前处于连接态的USIM的业务为终端设备支持的业务中优先级最高的业务的情况下，可以向AMF网元发送免寻呼指示，不仅可以避免寻呼消息对重要业务的影响，而且可以减少不必要消息的传输，从而可以节约传输资源。
作为一种可能的实施方式，当第二业务结束时，终端设备可以向AMF网元发送用于指示解除免寻呼指示的解除免寻呼指示，以便AMF网元可以向终端设备上第一USIM重新发送寻呼消息。
作为一种可能的实施方式，第二业务的业务信息可以包括第二业务的优先级，也可以包括第二业务的业务类型信息，还可以包括第二业务的5QI、DSCP和QFI中的至少一种。
第三方面公开一种通信方法，用户面功能(user plane function，UPF)网元接收来自会 话管理功能(session management function，SMF)网元的第一指示信息，根据第一指示信息向SMF网元发送第一数据通知消息。其中，第一指示信息用于指示在第一USIM的数据通知消息中携带业务信息，或者用于指示当第一USIM的待发送下行数据为特定业务的数据时在数据通知消息中携带业务信息，第一数据通知消息用于通知存在第一USIM的待发送下行数据，第一数据通知消息携带第一USIM的待发送下行数据对应的第一业务的第二业务信息。UPF网元可以根据指示信息在数据通知消息中携带业务的业务信息，以便AMF网元能够在寻呼消息中携带业务的业务信息。
作为一种可能的实施方式，第一业务的第二业务信息可以包括第一业务的优先级，也可以包括第一业务的业务类型信息，还可以包括第一业务的5QI、DSCP和QFI中的至少一种。
第四方面公开一种通信方法，SMF网元接收来自UPF网元的第一数据通知消息，根据第一数据通知消息向AMF网元发送第二数据通知消息。其中，第一数据通知消息用于通知存在第一USIM的待发送下行数据，第一数据通知消息携带第一USIM的待发送下行数据对应的第一业务的第二业务信息，第二数据通知消息携带第一USIM的待发送下行数据对应的第一业务的第二业务信息。SMF网元可以根据UPF网元发送的数据通知消息携带的业务的业务信息在向AMF网元发送的数据通知消息中携带业务的业务信息，以便AMF网元能够在寻呼消息中携带业务的业务信息。
作为一种可能的实施方式，SMF网元可以向UPF网元发送第一指示信息，第一指示信息用于指示在第一USIM的数据通知消息中携带业务信息，或者用于指示当第一USIM的待发送下行数据为特定业务的数据时在数据通知消息中携带业务信息。SMF网元可以发送指示信息指示UPF网元在发送的数据通知消息中携带业务的业务信息，以便UPF网元向SMF网元发送的第一数据通知消息中携带业务的业务信息，SMF网元向AMF网元发送的第一数据通知消息中携带业务的业务信息，从而AMF网元能够在寻呼消息中携带业务的业务信息。
作为一种可能的实施方式，SMF网元可以接收来自策略控制功能(policycontrol function，PCF)网元的第一指示信息，也可以接收来自统一数据管理(unified data management，UDM)网元的第一指示信息。
作为一种可能的实施方式，SMF网元可以接收终端设备的USIM能力信息，根据终端设备的USIM能力信息向UPF网元发送第一指示信息。其中，USIM能力信息用于指示终端设备支持至少两个USIM，第一USIM为终端设备对应的一个USIM。
作为一种可能的实施方式，第一业务的第二业务信息可以包括第一业务的优先级，也可以包括第一业务的业务类型信息，还可以包括第一业务的5QI、DSCP和QFI中的至少一种。
第五方面公开一种通信方法，AMF网元接收来自SMF网元的携带第一USIM的待发送下行数据对应的第一业务的第二业务信息的第二数据通知消息，根据第二通知消息向终端设备发送寻呼消息。第一USIM为终端设备对应的一个USIM，寻呼消息用于寻呼第一USIM对应的用户，寻呼消息携带第一业务的第一业务信息。可见，在SMF网元下发的数据通知消息中携带业务的业务信息的情况下，寻呼消息中会携带业务的业务信息，以便终端设备可以根据业务的业务信息确定是否响应寻呼消息。
作为一种可能的实施方式，当第一业务的第一业务信息与第一业务的第二业务信息不相同时，AMF网元可以根据第一业务的第二业务信息获得第一业务的第一业务信息。
作为一种可能的实施方式，第一业务的第二业务信息不包括第一业务的优先级，第一业务的第一业务信息包括第一业务的优先级，AMF网元可以接收终端设备的业务优先级信息，根据第一业务的第二业务信息和终端设备的业务优先级信息获得第一业务的第一业务信息。
作为一种可能的实施方式，AMF网元接收来自终端设备的第二业务的业务信息，根据第一业务的第二业务信息和第二业务的业务信息向终端设备发送寻呼消息。其中，第二业务为终端设备的第二USIM的当前业务，第二USIM处于连接态。可见，AMF网元可以根据待发送业务的业务信息和终端设备上当前处于连接态的USIM的业务的业务信息确定是否向终端设备发送寻呼消息，而不是盲目的发送寻呼消息，可以避免不必要的寻呼消息，从而可以节约传输资源。
作为一种可能的实施方式，当AMF网元根据第一业务的第二业务信息和第二业务的业务信息确定第一业务的优先级高于第二业务的优先级时，AMF网元向终端设备发送寻呼消息。可见，在待传输业务的优先级高于终端设备上当前处于连接态的USIM的业务的优先级的情况下，才发送寻呼消息，可以保证先处理优先级高的业务，从而可以保证重要的业务先处理。

为了更好地理解本发明实施例公开的一种通信方法及设备，下面先对本发明实施例使用的一个应用场景进行描述。一个终端设备内部可以包括一个USIM，也可以包括两个USIM，还可以包括两个以上USIM。下文以两个USIM为例进行说明。终端设备的两个USIM可以都是面向公网的，也可以两个USIM中一个USIM用于公网，另一个USIM用于私网或企业网。其中，USIM可以为用户身份识别(subscriber identification module，SIM)卡，也可以为USIM卡。请参阅图3，图3是本发明实施例公开的一种两个USIM终端设备的示意图。
如图3所示，两个USIM终端设备包括被动模式(passive mode)、双卡双待(dual SIM dual standby，DSDS)模式和双卡双通(dual SIM dual active，DSDA)模式。
被动模式：终端设备设置有一个接收机和一个发射机，任何时刻仅有一个USIM可以使用这个接收机和这个发射机。
DSDS模式：包括DSDS单接收机和DSDS双接收机。DSDS单接收机：终端设备设置有一个接收机和一个发射机，两个USIM均处于空闲态时，都可以接收网络侧寻呼；当有一个USIM处于连接态时，另一个USIM既不能接收网络寻呼也不能发送数据，即仅有一个USIM处于连接态，发射机和接收机只能为单一USIM传输业务数据。DSDS双接收机：终端设备设置有两个接收机和一个发射机，两个USIM均处于空闲态时，都可以接收网络寻呼，可以分别在不同的接收机上接收；当有一个USIM处于连接态时，另一个USIM能使用另一个接收机接收网络寻呼；一个发射机只能为一个USIM使用。
DSDA模式：终端设备设置有两套接收机和发射机，两个USIM可以独立工作。
在两个USIM均在网络中注册后，USIM的状态可以是连接态，也可以是空闲态。假设在任一USIM处于连接态的情况下，终端设备与网络之间有信令连接，终端设备可以进行业务数据传输。在两个USIM均处于空闲态的情况下，终端设备与网络之间没有信令连接，终端设备不能进行业务数据传输，终端设备识别接收网络广播消息，并周期性地向网络进行注册。
请参阅图4，图4是本发明实施例公开的一种DSDS模式的DSDS双接收机的寻呼示意图。如图4所示，终端设备设置有双接收机和单一发射机，在USIM1处于连接态，且USIM1与网络之间有业务数据进行传输，以及USIM2处于空闲态的情况下，若网络有业务数据需要下发送给USIM2，则网络向USIM2发送寻呼消息。在USIM2接收到寻呼消息后，若终端设备响应该寻呼消息，则USIM1的业务数据会被挂起，USIM2进入连接态；若终端设备不响应该寻呼消息，则USIM1和USIM2均保持现状。不论终端设备响应寻呼消息还是不响应寻呼消息，都会导致某个USIM的业务被影响。
另一个应用场景可以是，DSDS模式下，终端设备设置有双接收机和单一发射机，一个发射机可以通过时分复用方式为两个处于连接态的USIM使用。例如，在USIM1处于连接态，且USIM2处于空闲态的情况下，USIM1的业务数据传输独享该终端设备的时间资源， 网络向USIM2发送寻呼消息。在USIM2接收到寻呼消息后，若终端设备响应该寻呼消息，USIM2进入连接态，USIM1和USIM2的业务数据会通过时分复用方式发送给网络，此时，由于用于USIM1业务传输的时间资源变少，USIM1的业务数据传输性能会受到影响；若终端设备不响应该寻呼消息，则USIM1和USIM2均保持现状，USIM2中业务数据无法传输。因此，不论终端设备响应寻呼消息还是不响应寻呼消息，都会导致某个USIM的业务被影响。
其中，背景技术和应用场景中描述的一个USIM可以对应一个用户。下面实施例中一个USIM可以对应一个用户，即用户与USIM可以一一对应，也可以一个USIM对应两个或两个以上用户，不予限制。
基于图1和图2所示的网络架构，请参阅图5，图5是本发明实施例公开的一种通信方法的流程示意图。如图5所示，该通信方法可以包括以下步骤。
501、SMF网元向UPF网元发送第一指示信息。
其中，第一指示信息可以用于指示在第一USIM的数据通知消息中携带业务信息，也可以指示当第一USIM的待发送下行数据为特定业务的数据时在数据通知消息中携带业务信息。可选地，第一指示信息包括与特定业务对应的业务检测规则信息。其中，业务检测规则信息可以用于指示业务检测规则，该信息可以包括数据包过滤(packet filter)或业务数据流模板。该数据包过滤为用于过滤数据的规则。该特定业务可以为某个商家的视频业务、某类视频业务等。
其中，第一USIM为终端设备的至少两个USIM中的任一USIM。
其中，终端设备存在至少两个USIM，即终端设备上安装有至少两个USIM，且该至少两个USIM均是在网络中注册过，并能够正常工作的USIM，后续可以称之为终端设备的至少两个USIM。
可选地，终端设备的至少两个USIM在同一时间只能有一个USIM处于连接态。终端设备上可以设置有一个发射机。终端设备上还可以设置有至少两个接收机，可以为至少两个USIM中每个USIM分别设置一个接收机，每个USIM的寻呼消息都是通过对应的接收机接收的；也可以为两个或两个以上USIM设置一个接收机，此时，某一个接收机可能并不是固定为某一个USIM使用的，可以是至少两个USIM中每个USIM都可以使用同一个接收机，也可以是至少两个USIM中部分USIM可以使用同一个接收机。在一个USIM卡槽对应一个USIM的情况下，终端设备可以设置有至少两个USIM卡槽，每个USIM卡槽可以安装一个USIM。在一个USIM卡槽对应两个或两个以上USIM的情况下，终端设备上可以设置较少的USIM卡槽。
其中，业务信息可以包括业务的优先级，也可以包括业务的业务类型，还可以包括业务的5QI、DSCP和QFI中的至少一种。
其中，业务类型信息可以为业务类型(service type)标识，还可以业务类型的其它信息，在此不作限定。业务类型可以有粗细粒度。对于粗粒度，业务类型可以分为数据、语音、视频、短消息等。以2bit为例进行说明，当业务类型标识为00时，该业务类型标识所标识的业务为数据业务，当业务类型标识为01时，该业务类型标识所标识的业务为语音业务，当业务类型标识为10时，该业务类型标识所标识的业务为视频业务。对于细粒度，语音业 务可以分为基于IMS的电话语音、基于电路交换(circuit switched，CS)的电话语音、经过互联网(internet)的语音等，视频业务可以分为基于IMS的视频、经过互联网的视频呼叫、经过互联网的在线视频，短消息业务可以分为基于IMS的短消息、基于CS的短消息、基于互联网的短消息，数据业务可以为网页浏览、地图应用等。基于IMS的电话语音可以为新无线语音承载(voice over new radio，VoNR)、长期演进语音承载(voice over long term evolution，VoLTE)等，基于CS的电话语音可为经过电路域回落(circuit switched fallback，CSFB)的语音等，经过互联网的语音可以为即时通信语音业务等。基于IMS的视频可以为高清视频通话(video over long term evolution，ViLTE)等，经过互联网的视频呼叫可以为即时通信应用视频等，经过互联网的在线视频可以为浏览器上的各种视频。
502、UPF网元根据第一指示信息向SMF网元发送第一数据通知消息。

具体的，假设第一指示信息用于指示当第一USIM的待发送下行数据为特定业务的数据时在数据通知消息中携带业务信息的指示信息，那么若该终端设备的第一USIM的待发送下行数据为特定业务的下行数据，则UPF网元可以向SMF网元发送第一数据通知消息，该第一数据通知消息可以携带该待发送下行数据对应的第一业务的第二业务信息。若该终端设备的第一USIM的待发送下行数据不是特定业务的下行数据，则UPF网元可以向SMF网元发送不携带第一业务的第二业务信息的第一数据通知消息。

其中，第一数据通知消息用于通知存在第一USIM的待发送下行数据。第一数据通知消息可以携带第一USIM的待发送下行数据对应的第一业务的第二业务信息。待发送下行数据对应的第一业务，即待发送下行数据是第一业务的待发送下行数据。第一业务可以为视频、音频等。
其中，第一数据通知消息还可以携带第一USIM的USIM标识或与第一USIM的USIM标识存在关联关系的标识，可以表明存在第一USIM的待发送下行数据。在不同通信系统中USIM标识可以不同，例如，在4G通信系统中，USIM标识可以为国际移动用户识别码(international mobile subscriber identity，IMSI)，在5G通信系统中，USIM标识可以为用户永久标识(subscription permanent identifier，SUPI)。与第一USIM的USIM标识存在关联关系的标识可以是N4会话标识，SMF网元可以根据N4会话标识映射出USIM标识。与第一USIM的USIM标识存在关联关系可以是与第一USIM的USIM标识存在直接关联关系，也可以是存在间接关联关系。关联关系可以以表格的形式存在，也可以以其它形式存在。第一USIM的USIM标识或与第一USIM的USIM标识可以标识第一数据通知消息为针对第一USIM的数据通知消息。
