具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请可以应用于各种通信系统，例如：新无线(new radio，NR)、未来通信系统等。NR有时也可称为5G系统。
本申请对终端的类型不做具体限定，例如可以是用户设备、接入终端、终端设备、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、无线网络设备、用户代理或用户装置。终端可以包括但不限于移动台(mobile station，MS)、移动电话(mobile telephone)、用户设备(user equipment，UE)、手机(handset)、便携设备(portable equipment)、蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、物流用的射频识别(radio frequency identification，RFID)终端设备，具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它设备、车载设备、可穿戴设备或物联网、车辆网中的终端设备以及未来网络中的任意形态的终端设备等。
本申请提及的接入网设备有时也可称为基站，对该接入网设备的类型不做具体限定，还可以是NR或5G的基站(gNB)，本申请实施例对此不作具体限定。
作为一种可能的方式，基站可以由集中式单元(centralized unit,CU)和分布式单元(distributed unit,DU)构成。一个CU可以连接一个DU，或者也可以多个DU共用一个CU，可以节省成本，以及易于网络扩展。CU和DU的切分可以按照协议栈切分，其中一种可能的方式是将无线资源控制(radio resource control，RRC)、服务数据映射协议栈(service data adaptation protocol，SDAP)以及分组数据汇聚协议(packet data convergence protocol，PDCP)层部署在CU，其余的无线链路控制(Radio Link Control，RLC)层、介质访问控制(media access control，MAC)层以及物理层部署在DU。本申请中并不完全限定上述协议栈切分方式，还可以有其它的切分方式。当接入网设备是例如上述的CU和DU的架构时，本申请实施例提到基站或接入网设备时，可能是指CU，也可能是指DU，或者是由CU和DU构成的系统，具体依赖于相应的实现功能。
可以理解的是，本申请实施例中所提到的基站不限于上述的形式，可以是任何提供部署在无线接入网中用以为终端提供无线通信功能的装置。
上文指出，相关技术中，移动终核心网需要向去激活态的终端发送数据或信令时，会直接把数据或信令发送给配置终端进入去激活态的源基站，这样可能会造成通信错误。
以接入网设备为基站为例，当其他通信设备(如核心网设备)需要向去激活态的终端发送数据时，该其他通信设备通常会直接将该数据或信令发送给配置终端进入去激活态的终端的源基站。但是，如果源基站在自己的覆盖范围内没有寻呼到该终端，则可能会丢弃该数据或信令，从而造成通信错误。
下面对本申请实施例提供的通信方法进行详细描述。
图1是本申请实施例提供的通信方法的示意性流程图。图1的方法包括：
步骤110：第一通信设备向第二通信设备发送第一通知，通知第二通信设备发起第二通信设备触发的的寻呼(paging)；
步骤120：第二通信设备根据所述第一通知，对终端进行寻呼。所述终端可以为处于去激活态的终端。
可以理解地，第二通信设备触发的寻呼可以是基站触发的寻呼，或者称为RAN寻呼。基站触发的寻呼或RAN寻呼用于寻呼去激活态的终端设备。
本申请实施例中，第一通信设备主动通知具有寻呼功能的通信设备发起由第二通信设备触发的寻呼，这样可以避免不必要的通信错误。
终端的状态可以包括空闲态，激活态和去激活态。上文中的终端可以是处于去激活(inactive)状态的终端。去激活态可以理解为一种节能的状态，处于去激活态的终端可以周期性地醒来，并检测是否存在自己的寻呼消息。
本申请实施例对第一通信设备的类型不做具体限定，可以是能够与第二信设备通信，并触发第二通信设备发起第二设备触发的寻呼的任意通信设备。可选地，作为一个示例，第一通信设备可以是核心网(core network，CN)设备，例如，该第一通信设备可以是核心网中的移动性管理实体(mobility management entity，MME)，接入移动管理功能(Access and Mobility Management Function，AMF)。
本申请实施例对第二通信设备或第三通信设备的类型不做具体限定，可以是能够对终端进行寻呼的任意通信设备。可选地，作为一个示例，第二通信设备和第三通信设备可以是接入网设备。例如，第二通信设备和第三通信设备可以是基站，CU，DU中的任意一种。进一步地，在一些实施例中，该第二通信设备可以是将终端的状态配置为去激活状态的接入网设备，或者称为源基站。
第一通知可通知或可专门通知第二通信设备发起第二通信设备触发的寻呼。一种可能的方式中，第一通知可通知或专门通知第二通信设备在去激活态的终端的无线接入网络通知区(RAN notification area，RNA)发送第二通信设备触发的寻呼，以寻呼该终端。
可选地，第一通信设备可以在接收到第二通信设备发送的指示终端进入去激活状态的消息之后执行上述步骤110。该指示终端进入去激活状态的消息例如可以是终端状态报告消息。以第一通信设备为核心网设备，第二通信设备为接入网设备为例。当接入网设备(或者称为源基站)通知核心网设备终端进入去激活状态后，当该去激活状态的终端的下行数据或信令到达核心网时，核心网设备可以不向该去激活态的终端的源基站发送该去激活状态的终端下行数据和/或下行信令。比如，在有下行数据和/或下行信令需要向该进入去激活状态的终端发送的情况下，核心网设备向源基站发送第一通知。本申请实施例对第一通知的触发条件不做具体限定。
可选的，当有下行数据和/或下行信令需要向终端发送的情况下，核心网设备根据接入网设备发送的终端状态报告消息确定该终端是否为去激活状态的终端。例如，在接收到终端的下行数据或下行信令之前，核心网设备接收到指示终端处于去激活态的终端状态报告消息；核心网设备根据该终端状态报告消息，将该终端的状态记录为去激活态。
作为一个示例，步骤110可以包括：在需要向去激活状态的终端传输数据或信令情况下，第一通信设备向第二通信设备发送第一通知。
在一些实施例中，在寻呼到该终端之后，第一通信设备向寻呼到该终端的通信设备发送该终端的数据或信令，寻呼到该终端的通信设备向终端发送所述数据或信令。
以第一通信设备为核心网设备，第二通信设备为接入网设备为例，当核心网设备需要向终端传输下行数据或下行信令时，核心网设备可以向接入网设备发送第一通知。例如，核心网设备在接收到去激活态的终端设备的数据，核心网设备非接入层协议数据单元(non-access stratum protocol data unit，NAS PDU)、下行分类1(或分类2)下一代应用协议栈(Downlink class 1(或class 2)NG Application Protocol，NGAP，DL class 1(或class 2)NGAP)信令。
本申请实施例中，第一通信设备确定终端处于去激活态，生成第一通知，且发送第一通知以通知具有寻呼功能的通信设备对终端进行寻呼之后，再向成功寻呼到终端的通信设备发送数据或信令，这样可以避免数据或信令的丢失。
本申请实施例对承载第一通知的消息类型不做具体限定，可以是一个专门的消息，也可以承载在兼具其他作用的消息中，例如寻呼消息。以第一通信设备为核心网设备，第二通信设备为接入网设备为例，第一通知可以是寻呼请求消息。该寻呼请求消息可以是终端专用的信令。该寻呼请求消息也可称为请求无线接入网络寻呼(request RAN paging)消息，无线接入网寻呼通知(RAN paging notification)消息，无线接入网寻呼控制(RAN paging control)消息，无线接入网寻呼请求(RAN paging request)消息，或者其他类似的消息名称。仍以第一通信设备为核心网设备，第二通信设备为接入网设备为例，第一通知还可以是终端(如UE)上下文修改消息等。
本申请实施例对通过第一通知指示第二通信设备发起第二通信设备触发的寻呼的方式也不做具体限定，可以显式指示，也可以隐式指示。以显式指示为例，可以在第一通知消息中包括可用于指示第二通信设备发起第二通信设备触发的寻呼的信元。该信元在第一通知中可以是强制(mandatory)类型的信元，即该信元必须携带在该第一通知中。该信元也可以是可选(option)类型的信元，即该信元可以携带在该第一通知中，也可以不携带在该第一通知中。以隐式指示为例，通知消息本身可直接用于触发第二通信设备发起针对终端的寻呼，无需设置专门的信元。
下面结合具体的实施例，对第一通知中可以包括的信息或信元的类型进行举例说明。
可选地，在一些实施例中，第一通知可以包括指示所述第二通信设备对所述终端发起所述第二通信设备触发的寻呼的第一指示信息(或称RAN paging indicator)；或者，第一通知可以包括终端的第一通信设备接入点标识；或者，第一通知可以包括终端的第二通信设备接入点标识；或者，第一通知可以包括指示所述第二通信设备对所述终端发起所述第二通信设备触发的寻呼的第一指示信息和终端的第一通信设备接入点标识；或者，第一通知可以包括指示所述第二通信设备对所述终端发起所述第二通信设备触发的寻呼的第一指示信息和终端的第二通信设备接入点标识。
第二通信设备触发的寻呼可以是基站触发的寻呼，或者称为RAN寻呼。终端的第一通信设备接入点标识和/或终端的第二通信设备接入点标识可以用于指示第二通信设备向该终端发起第二通信设备触发的寻呼。可以理解的，第二通信设备基于终端的第一通信设备接入点标识和/或终端的第二通信设备接入点标识唯一确定该去激活态的终端的接入网标识。作为一种示例，第二通信设备发起第二通信设备触发的的寻呼中携带该去激活态的 终端的接入网标识。终端的接入网标识用于在接入网或终端配置的RNA内唯一识别终端。
可选地，在一些实施例中，第一通知还包括下列信息或信元中的至少一种：用于第二通信设备确定寻呼终端时所使用的寻呼帧的信息、终端的标识、终端寻呼优先级(paging priority)、终端的寻呼域、寻呼原因以及终端的寻呼周期。
终端的标识例如可以包括终端的以下标识中的至少一种：系统架构演进临时移动用户标识(system architecture evolution temporary mobile subscriber identity，S-TMSI)、国际移动用户识别码(international mobile subscriber identification number，IMSI)或者其它可以唯一标识终端的标识。可以理解的，终端的标识可以用于指示第二通信设备向该终端发起第二通信设备触发的寻呼。比如终端的标识为S-TMSI，第二通信设备基于该终端的S-TMSI，唯一确定该去激活态的终端的接入网标识。作为一种示例，第二通信设备发起第二通信设备触发的的寻呼中携带该去激活态的终端的接入网标识。终端的接入网标识用于在接入网或终端配置的RNA内唯一识别终端。
用于第二通信设备确定寻呼终端时所使用的寻呼帧的信息例如可以是终端标识索引(也可称为UE identity index value)，第一通信设备可以基于终端标识索引计算寻呼帧的信息。
以第一通信设备为核心网设备，终端为UE为例，终端的第一通信设备接入点标识可以是UE的核心网接入点标识，如AMF UE NGAP ID，该标识可用于在核心网和接入网的接口的核心网侧设备唯一识别UE。
以第二通信设备为基站，终端为UE为例，终端的第二通信设备接入点标识可以是UE的基站接入点标识，如RAN UE NGAP ID，该标识可用于在核心网和接入网的接口的接入网侧设备唯一识别UE。

表格中信元类型M表示为(mandatory)类型的信元，即该信元必须携带在该第一通知中。信元类型O表示为可选(optional)类型的信元，即该信元可以携带在该第一通知中，也可以不携带在该第一通知中。应理解，表1对应第一通知包括第一指示信息的一种示例方式，表2对应第一通知包括终端的第一通信设备接入点标识和终端的第二通信设备接入点标识的一种示例方式。上述表1和表2仅作为一种示例，本申请对此不做限定。
进一步地，在一些实施例中，第一通信设备可以接收第二通信设备或第三通信设备发送的反馈，指示是否成功寻呼到该终端。下面给出第一通信设备可能接收到的反馈消息的几种示例。
作为一个示例，图1的方法还可包括：第一通信设备接收第二通信设备发送的通知终端被成功寻呼到的第二通知。此处，终端可以是被第二通信设备或者第三通信设备成功寻呼到。作为一个示例，当终端是被第三通信设备成功寻呼到时，第三通信设备需要通知第二通信设备该终端在第三通信设备被成功寻呼到。可以理解的，第三通信设备还可以通知第二通信设备被成功寻呼到的终端的标识。应理解，终端的标识可以是S-TMSI、IMSI、接入网标识、终端的核心网接入点标识和终端的接入网接入点标识中的至少一种。
第三通信设备可以是与第二通信设备位于同一RNA(或称终端配置的RNA)中的通信设备(如基站)。
可选地，第二通知中还可以包括成功寻呼到的终端的通信设备标识。作为一个示例，假设无论第二通信设备还是第三通信设备成功寻呼到终端，均由第二通信设备向第一通信设备发送上述第二通知。在这种情况下，可以采用如下示例：如果第二通信设备成功寻呼到终端，则第二通信设备向第一通信设备发送的第二通知中不携带第二通信设备的标识；该示例可以隐式地指示终端被第二通信设备成功寻呼到；如果第三通信设备成功寻呼到终端，则第二通信设备向第一通信设备发送的第二通知中携带第三通信设备的通信设备标识；该示例可以显式地指示终端被第三通信设备寻呼到。作为一个示例，第二通知中还可以携带成功寻呼到的终端的标识。终端的标识可以是S-TMSI、IMSI、接入网标识、终端的核心网接入点标识和终端的接入网设备接入点标识中的至少一种。
作为另一个示例，图1的方法还可包括：第一通信设备接收第三通信设备发送的通知终端被第三通信设备成功寻呼到的第二通知。第三通信设备可以是与第二通信设备位于该同一RNA(或称终端对应的RNA)中的通信设备(如基站)。以第二通信设备为源基站， 第三通信设备为目标基站为例。源基站为配置终端进入去激活态的服务基站，目标基站为终端的RNA内的除源基站以为的其它基站。源基站接收到第一通知之后，源基站可以向终端对应的RNA中的部分或全部目标基站发送指示，指示该部分或全部目标基站向该终端发送寻呼。本申请实施例对承载第二通知的消息类型不做具体限定，可以是一个专门的消息，也可以承载在兼具其他作用的消息中，如可以包括以下消息中的一种：路径切换(path switch)消息、终端的状态通知消息以及寻呼响应消息。可选地，该第二通知可以显式地通知终端被成功寻呼到，如第二通知中添加用于指示终端被成功寻呼到的信息或信元。在另一些实施例中，该第二通知消息可以隐式地通知终端被成功寻呼到，而无需设置专门的信元。作为一个示例，第二通知中还可以携带成功寻呼到的终端的标识。终端的标识可以是S-TMSI、IMSI、接入网标识、终端的核心网接入点标识和终端的接入网设备接入点标识中的至少一种。
作为另一个示例，若RNA内的通信设备均没有成功寻呼到该终端，图1的方法还可包括：第一通信设备接收第二通信设备发送的通知终端未被成功寻呼到的第三通知。或者，第一通信设备接收到第二通信设备发送的通知在RNA内未成功寻呼到终端的第三通知。作为一个示例，第三通知中还可以携带未被成功寻呼到的终端的标识。终端的标识可以是S-TMSI、IMSI、接入网标识、终端的核心网接入点标识和终端的接入网设备接入点标识中的至少一种。
本申请实施例对承载第三通知的消息类型不做具体限定，可以是一个专门的消息，也可以承载在兼具其他作用的消息中，如可以包括以下消息中的一种：寻呼失败消息和终端的上下文释放命令(或称终端的上下文释放指示)。在一种可能的方式中，该第三通知可以显式地通知终端未被成功寻呼到，如第三通知中添加寻呼失败指示信息的信息或信元。在一种可能的方式中，该第三通知可以隐式地通知终端未被成功寻呼到，而无需设置专门的信元。第一通信设备可以进一步确定是否对该终端发起第一通信设备触发的寻呼，可选的，可以为核心网寻呼。
下面结合具体例子，更加详细地描述本申请实施例。应注意，图2的例子仅仅是为了帮助本领域技术人员理解本申请实施例，而非要将本申请实施例限于所例示的具体数值或具体场景。本领域技术人员根据所给出的图2的例子，显然可以进行各种等价的修改或变化，这样的修改或变化也落入本申请实施例的范围内。
应理解，图2中的核心网设备对应于上文中的第一通信设备，源基站对应于上文中的第二通信设备，目标基站对应于上文中的第三通信设备，源基站为配置终端进入去激活态的基站，目标基站为终端的RNA内的除源基站外的其它基站。应理解，源基站会为去激活态的终端配置RNA，RNA的范围可以仅包括源基站，也可以包括源基站和至少一个目标基站。图2以RNA的范围包括源基站和至少一个目标基站为例。图2的方法包括步骤202-步骤226，下面对这些步骤进行详细描述。
步骤202：源基站向核心网设备发送终端进入去激活状态的报告。该报告可以是终端状态通知消息。
在步骤202之前，源基站可以先将终端的状态配置为去激活状态。比如，源基站确定一段时间内没有该终端的上下行数据或信令发送，为了终端节能，配置终端进入去激活态；或者源基站拥塞时，也可以直接配置终端进入去激活态。上述场景仅作为一种示例，本申 请实施例对此不作限定。
步骤204-206：核心网设备向源基站发送寻呼请求(对应于上文中的第一通知)，通知源基站在终端对应的RNA内发起源基站触发的寻呼(或称为RAN寻呼)。源基站为配置终端进入去激活状态的基站。
比如，当去激活状态的终端的下行数据或信令到达核心网时，核心网设备可以向源基站发送寻呼请求。
该寻呼请求的格式可以参见上文对第一通知的描述，例如可以采用上文中的表1或表2所示的形式，或者其它可能的形式，此处不再详述。
步骤208-212：源基站在终端的RNA内发起RAN寻呼，以寻呼该终端。
例如，源基站可以在自己的覆盖范围内寻呼终端，比如执行步骤212。此外，源基站可以请求RNA内的其他目标基站发送RAN寻呼，以便其他目标基站在各自的覆盖范围内寻呼该终端，比如执行步骤208-210。
接下来，图2的方法可以有三种情况。
情况1：终端在源基站的覆盖范围内被成功寻呼到。情况1包括步骤214-216。
步骤214：源基站接收到终端的响应消息。
该响应消息可以为恢复请求(resume request)消息或恢复完成(resume complete)消息，或者其它消息。
步骤216：源基站向核心网设备发送终端被成功寻呼到的报告(可对应于上文中的第二通知)。
该报告可以是终端状态报告消息，可用于通知核心网终端在源基站的覆盖范围内被成功寻呼到。
情况2：终端在目标基站的覆盖范围内被成功寻呼到。情况2包括步骤218-224。
步骤218：目标基站接收到终端的响应消息。
该响应消息可以为恢复请求(resume request)消息或恢复完成(resume complete)消息或其它消息。
步骤220：目标基站向源基站发送寻呼成功指示消息。
该寻呼成功指示消息可以包括目标基站的设备标识；该寻呼成功指示消息还可以包括终端的标识；终端的标识可以是S-TMSI、IMSI、接入网标识、终端的核心网接入点标识和终端的接入网设备接入点标识中的至少一种。该寻呼成功指示消息可以为上下文获取请求(retrieve context fetch request)消息或其它寻呼成功指示消息。
步骤222：源基站向核心网设备发送终端被成功寻呼到的报告(可对应于上文中的第二通知)。
该报告可以是终端状态报告消息，可用于通知核心网终端在目标基站的覆盖范围内被成功寻呼到。
进一步地，在一些实施例中，该终端状态报告消息可以包括目标基站的设备标识。应理解，该终端状态报告消息还可以包括终端的标识。终端的标识可以是S-TMSI、IMSI、接入网标识、终端的核心网接入点标识和终端的接入网设备接入点标识中的至少一种。
可替换地，也可以不执行步骤220-222，直接执行步骤224。即由目标基站向核心网设备发送终端状态报告。该终端状态报告消息还可以包括终端的标识。终端的标识可以是 S-TMSI、IMSI、接入网标识、终端的核心网接入点标识和终端的接入网设备接入点标识中的至少一种。
情况3：终端未被成功寻呼到。情况3包括步骤226。
步骤226：源基站向核心网设备发送寻呼失败消息(可对应于上文中的第三通知)。
寻呼失败消息可以用于通知核心网设备寻呼失败。或者寻呼失败消息可以用于通知核心网源基站在该终端的RNA内没有寻呼到该终端。寻呼失败消息可以携带终端的标识。终端的标识可以是S-TMSI、IMSI、接入网标识、终端的核心网接入点标识和终端的接入网设备接入点标识中的至少一种。
可以理解的，核心网或基站可以执行上述实施例中的部分或全部步骤，这些步骤或操作仅是示例，本申请实施例还可以执行其它操作或者各种操作的变形。此外，各个步骤可以按照上述实施例呈现的不同的顺序来执行，并且有可能并非要执行上述实施例中的全部操作。
可以理解的是，上述第一通信设备、第二通信设备以及第三通信设备分别可以理解为是一个独立的网元，也可以分别理解为是可用于网元中的芯片，本申请实施例对此不做限定。
