Description

通信方法及相关装置
本申请要求于2022年09月20日提交中国专利局、申请号为202211146254.5，发明名称为“通信方法及相关装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
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及相关装置。
背景技术
网络设备对处于无线资源控制(radio resource control，RRC)空闲态、RRC非激活态，以及RRC连接态的终端设备，都可以发送寻呼消息，以通知终端设备执行相应的操作或者更新相关的参数。当前的寻呼流程中，由于终端设备需要监听每个寻呼时机(paging occasion，PO)，以及接收寻呼消息判断自己是否被寻呼，因此存在大量的能量消耗。
基于此，相关技术提出了基于终端设备寻呼能力的寻呼机制，例如，寻呼提前指示(paging early indication，PEI)寻呼机制。该寻呼机制的基本思想如下：将监听同一寻呼时机(paging occasion，PO)的终端设备进行分组，即把同一PO上终端设备分到不同的分组(subgroup)中。网络设备通过PEI指示本次寻呼所针对的终端设备所属的分组的相关信息，终端设备在接收到PEI时，根据PEI中携带的分组指示(subgroup indication)就能判断本次寻呼是否针对自己所属的分组。如果是针对自己所属的分组，则终端设备按照原有寻呼机制监听PO，接收并解码寻呼消息；如果不是针对自己所属的分组，则终端设备针对本次寻呼不会监听PO和接收寻呼，因此，可节省终端设备的功耗。
需要说明的是，终端设备和网络设备对于终端设备寻呼能力具有一致的认识是终端设备和网络设备正常使用基于终端设备寻呼能力的寻呼机制的前提，因此，如何使终端设备和网络设备对于终端设备寻呼能力具有一致的认识，进而可正常使用基于终端设备寻呼能力的寻呼机制，以提高寻呼可靠性成为当前亟待解决的问题之一。

下面对本申请实施例涉及的相关技术特征进行解释说明。需要说明的是，这些解释是为了让本申请实施例更容易被理解，而不应该视为对本申请所要求的保护范围的限定。
1、寻呼(Paging)
网络设备可以通过寻呼来通知处于RRC空闲态(RRC_IDLE)或RRC非激活态(RRC_INACTIVE)的终端设备接收寻呼消息(paging message)。或者，网络设备可以通过寻呼来向处于RRC空闲态(RRC_IDLE)，RRC非激活态(RRC_INACTIVE)或RRC连接态(RRC_CONNECTED)的终端设备发送短消息(short message)以指示***信息(system information，SI)更新或地震海啸预警/商业移动告警(earthquake and tsunami warning system/commercial mobile alert service，ETWS/CAMS)。
请参见图2，图2是寻呼时机与寻呼周期的示意图。如图2所示，处于RRC空闲态或RRC非激活态的终端设备在每个寻呼周期(paging cycle)内监听一个自己的寻呼时机(paging occasion，PO)，以确定网络设备是否进行了寻呼。
通常来说，终端设备可以按照协议规定的计算公式，根据自己的终端设备标识信息和寻呼相关的参数计算自己的PO位置，不同终端设备计算出的PO位置可能相同，即可能存在多个终端设备监听同一PO。
具体地，寻呼的基本流程如下：
网络设备选择一定的寻呼范围，在PO内发送寻呼下行控制信息(downlink control information，DCI)。其中，寻呼范围是网络设备发送寻呼的区域。该区域由网络设备决定，例如，针对RRC空闲态终端设备， 网络设备可将该终端设备所属的注册区域(registration area)作为寻呼范围；针对RRC非激活态终端设备，网络设备可将该终端设备所属的基于接入网设备的通知区域作为寻呼范围，这里，基于接入网设备的通知区域可以是基于RAN的通知区域(RAN-based notification area，RNA)。其中，寻呼DCI中可能包括寻呼消息(paging message)的调度信息(包括调度寻呼消息的资源的时频域信息和其他调度信息)和/或短消息等，具体内容如下表1所示：
表1
其中，当终端设备接收到网络设备发送的寻呼DCI之后，根据寻呼DCI的内容确定后续操作，具体如下：
一种可能的实现中，如果寻呼DCI中包含寻呼消息的调度信息，则终端设备根据调度信息在物理下行共享信道(physical downlink shared channel，PDSCH)上接收并解码寻呼消息，然后根据寻呼消息的内容确定后续操作。其中，寻呼消息包含网络设备所寻呼的一个或多个终端设备的终端设备标识信息和/或被寻呼终端设备的接入类型信息。终端设备解码寻呼消息后确定该寻呼消息中是否包含自己的终端设备标识。通常来说，如果该寻呼消息中不包含自己的终端设备标识，则终端设备忽略该寻呼消息；如果该寻呼消息中包含自己的终端设备标识，则终端设备根据寻呼消息中的其他内容确定后续操作。
一种可能的实现中，如果寻呼DCI中包含短消息，则终端设备根据短消息的指示接收更新的***信息和/或地震海啸预警/商业移动告警。
一种可能的实现中，如果寻呼DCI中包括寻呼消息的调度信息以及短消息，则终端设备按照规定的流程分别接收寻呼消息，以及更新的***信息和/或地震海啸预警/商业移动告警。
需要说明的是，根据触发寻呼的网元不同，寻呼可以分为：核心网设备触发的核心网寻呼；接入网设备触发的接入网寻呼。网络设备可能对RRC_IDLE终端设备发起核心网寻呼，可能对RRC_INACTIVE终端设备发起核心网寻呼或接入网寻呼。
2、RRC空闲态(RRC_IDLE)
当终端设备处于RRC空闲态时，终端设备未保留无线资源控制(radio resource control，RRC)，上下文(context)等信息。RRC上下文是终端设备与网络设备之间建立通信的参数。RRC上下文可以包括安全上下文、终端设备的能力信息等。同时，终端设备也未与核心网设备建立连接。通常来说，处于RRC空闲态的终端设备仅周期性地唤醒以接收寻呼消息。
3、RRC非激活态(RRC_INACTIVE)
当终端设备处于RRC非激活态时，终端设备和网络设备之间保留了RRC上下文。同时，终端设备也与核心网设备建立连接，即核心网设备处于核心网连接态(CN_CONNECTED)。此时，切换到连接态以进行数据接收的流程是相对快速的，且无须产生额外的核心网信令开销。此外，处于RRC非激活态的终端设备也同样会进入休眠状态。因此，RRC非激活态能够满足降低连接时延、减小信令开销和功耗的需 求。
4、RRC连接态(RRC_CONNECTED)
当终端设备处于RRC连接态时，终端设备已建立RRC上下文。终端设备与网络设备之间建立通信所需的参数已被通信双方所获取。网络设备为接入的终端设备分配小区无线网络临时标识(cell radio network temporary identifier，C-RNTI)。同时，终端设备也与核心网设备建立连接。此时，如终端设备正在传送数据，则处于连续接收状态，直至数据传送完成而进入等待状态时，切换为连接态非连续接收(discontinuous reception，DRX)以节省功耗。如果后续还有数据待传送，终端设备则再次返回连续接收状态。此时，由于RRC上下文已建立，终端设备离开连接态DRX并准备连续接收所需的切换时间相对于从RRC空闲状态切换到RRC连接状态的时间要短得多。
5、唤醒信号(wake up signal，WUS)
节能信号(power saving signal)是一种为了达到终端设备节能目的而引入的信号，WUS属于节能信号的一种。WUS的类型可以有多种，包括DCI，物理层信号/序列(sequence)，媒体接入控制控制单元(medium access control control element，MAC CE)，RRC信令等。
针对寻呼过程，如下图3所示，网络设备可以在PO前或者PO上发送WUS，以指示终端设备接下来是否需要监听PO或接收寻呼消息，达到避免终端设备不必要地寻呼接收的效果。例如，如果当前网络设备不寻呼终端设备，则网络设备可在PO前发送WUS指示终端设备不需要监听关联的PO，则终端设备将不监听关联的PO；或者，网络设备可在PO前不发送WUS，当终端设备未检测/接收到WUS时，终端设备将不监听其关联的PO。
需要说明的是，一个WUS可以和一个或多个PO相关联，即可以用一个WUS来实现指示终端设备监听或不监听一个或多个PO。
在寻呼的场景下，WUS也可称为寻呼提前指示(paging early indication，PEI)。
6、终端设备分组(subgrouping)机制
现有的寻呼机制存在寻呼虚警(false alarm)的问题，即终端设备接收并解码了寻呼消息但发现网络设备实际并没有寻呼该终端设备。
寻呼虚警产生的主要原因是：存在多个终端设备监听同一PO的情况。当多个终端设备监听同一PO时，根据现有寻呼机制，终端设备在接收到寻呼DCI时只获得寻呼消息的调度信息，而不能区分出该寻呼消息是否为针对自己的寻呼消息，终端设备只能在随后接收并解码完PDSCH上的寻呼消息后，根据寻呼消息中的终端设备标识信息才能判断出本次寻呼是否针对自己，因此，对于实际未被寻呼的终端设备来说，就存在不必要的PDSCH接收解码，产生不必要的终端设备功耗。
终端设备分组机制是降低寻呼虚警的机制之一。该终端设备分组机制的基本思想如下：
将监听同一PO的终端设备进行分组，即把同一PO上终端设备分到不同的分组中。一个简单的示例：假设终端设备1，终端设备2，终端设备3，终端设备4和终端设备5监听相同的PO1，现将PO1上的这些终端设备分为3组，分组1包含终端设备1和终端设备2，分组2包含终端设备3和终端设备4，分组3包含终端设备5；
网络设备通过PEI指示本次寻呼所针对的终端设备所属的分组的相关信息(即，分组指示)。例如，分组指示可以是一个位图(bitmap)，每一比特(bit)对应一个分组；当某一分组内的终端设备被寻呼时，网络设备将该分组对应的比特设置为1，而其余未被寻呼的分组对应的比特设置为0；
终端设备在接收到PEI时，根据分组指示就能判断本次寻呼是否针对自己所属的分组。如果是针对自己所属的分组，则终端设备按照原有寻呼机制监听PO，即接收寻呼DCI，然后根据寻呼DCI中的调度信息接收并解码寻呼消息；否则，如果不针对自己所属的分组，则终端设备不会再监听PO和接收寻呼。
因此，终端设备分组机制可降低终端设备不必要的接收寻呼的概率，进而减少终端设备的额外功耗。
根据具体如何实现对终端设备进行分组，终端设备分组机制可有不同类型，例如，核心网设备控制的终端设备分组(以下简称核心网设备分组)和基于终端设备标识的终端设备分组(以下简称终端设备标识分组)。这里，核心网设备控制的终端设备分组可以是CN控制的分组(CN controlled subgrouping)，基于终端设备标识的终端设备分组可以是基于UE ID的分组(UE ID based subgrouping)。
其中，核心网设备分组是一种让核心网设备(例如，AMF)负责对终端设备进行分组的终端设备分组机制。可以包括如下步骤：
步骤1.终端设备可以上报终端设备辅助信息给核心网设备(例如AMF)，用于辅助核心网设备决定终端设备所属的分组。其中，辅助信息可以是终端设备的寻呼概率信息(paging probability)、终端设备的 功耗偏好信息(power profile)等等。
步骤2.核心网设备决定终端设备所属的分组，并将终端设备所属的分组信息(例如，终端设备的分组组号)发送至终端设备。这里，终端设备的分组组号可以是终端设备分组ID(UE subgroup ID)。其中，核心网设备如何决定终端设备所属的分组可以是核心网设备实现，例如，核心网设备可以参考终端设备提供的终端设备辅助信息和/或其他信息。
步骤3.核心网设备将终端设备所属的分组信息提供给接入网设备。
步骤4.接入网设备可能广播一些和核心网设备分组机制相关的参数。
其中，终端设备标识分组是一种基于终端设备的ID信息和接入网设备发送的分组总数确定终端设备所属分组的机制。例如，假设终端设备标识分组的总数为N，则一种简单的终端设备分组组号的计算方式为：subgroup ID＝UE_ID mod N，其中，subgroup ID表示分组组号，UE_ID表示终端设备标识。可以包括如下步骤：
步骤1.接入网设备广播一些和终端设备标识分组机制相关的参数。
步骤2.终端设备和接入网设备分别基于终端设备的ID信息和终端设备标识分组机制相关的参数，计算终端设备分组组号。
7、终端设备寻呼能力上报与维护
终端设备寻呼能力也称为与寻呼相关的终端设备能力。首先终端设备会在终端设备能力上报流程中上报终端设备的寻呼能力。具体的，终端设备的寻呼能力可以包括：①PEI能力：用于指示终端设备在哪些频带(band)上支持PEI。特别地，支持PEI也意味着支持终端设备标识分组机制；②PO标识(index)计算能力：用于指示终端设备是否支持在RRC_INACTIVE态下时使用RRC_IDLE态下的PO标识；③接收天线通道数(Rx branch)能力：用于指示降低能力(reduced capability，RedCap)终端设备支持的接收天线通道数目；④半双工能力：用于指示RedCap终端设备是否支持半双工/在哪些频带上支持半双工；⑤下行调度能力：用于指示终端设备是否支持针对PDSCH的大于0的下行调度时隙偏移值(DL scheduling slot offset)；⑥支持频带能力：用于指示终端设备支持的频带。
接入网设备接收到终端设备上报的寻呼相关的终端设备能力后，基于寻呼相关的终端设备能力生成终端设备无线寻呼信息消息(UERadioPagingInformation message)。接入网设备将该消息发送至核心网。核心网接收并保存接入网设备发送的终端设备无线寻呼信息消息。
对于核心网寻呼：核心网发起对某终端设备的寻呼时，核心网将该终端设备的终端设备无线寻呼信息再转发至参与本次寻呼的各个接入网设备。接入网设备接收到终端设备的终端设备无线寻呼信息后，可根据其中的相关终端设备能力，确定如何对该终端设备发起寻呼。
对于接入网寻呼：锚点(anchor)接入网设备发起对某终端设备的寻呼时，锚点接入网设备将该终端设备的终端设备无线寻呼信息再转发至参与本次寻呼的各个接入网设备。接入网设备接收到终端设备的终端设备无线寻呼信息后，可根据其中的相关终端设备能力，确定如何对该终端设备发起寻呼。
需要说明的是，接入网设备在接收到终端设备寻呼能力的上报后，可能无法解析终端设备上报的寻呼能力，进而无法将终端设备上报的寻呼能力放入终端设备无线寻呼信息消息以发送至核心网，而终端设备上报后即认为网络设备已获知了自己的寻呼能力，因而认为网络设备会采用基于终端设备寻呼能力的寻呼机制，而网络设备由于并未获知终端设备上报的寻呼能力，仍会采用原有寻呼机制进行寻呼，导致终端设备无法正常接收到网络设备的寻呼。例如，终端设备上报PEI能力，但接入网设备未升级至支持PEI特性的版本，因而无法解析终端设备上报的PEI能力，进而无法将终端设备上报的PEI能力放入发送给核心网设备的终端设备无线寻呼信息消息中，核心网设备未获知终端设备上报的PEI能力。因而，当核心网设备进行寻呼时，核心网设备推送至各个接入网设备的终端设备寻呼能力信息中将不包含终端设备上报的PEI能力。或者，接入网设备寻呼时，锚点接入网设备推送至各个接入网设备的终端设备寻呼能力信息中将不包含终端设备上报的PEI能力。然而，终端设备无法获知上述情况，而是会认为自己已上报过PEI能力，网络设备已获知终端设备的PEI能力信息，因此，终端设备进入RRC_IDLE/RRC_INACTIVE态后，将在支持PEI特性的接入网设备下使用基于PEI的寻呼机制，但接入网设备由于获取不到终端设备上报的PEI能力，不会使用PEI寻呼该终端设备，具体地，终端设备监听PEI但接入网设备不会给该终端设备发送PEI，导致终端设备无法被寻呼到。也就是说，终端设备和网络设备之间的对于终端设备寻呼能力具有一致的认识是实现终端设备和网络设备正常使用基于终端设备寻呼能力的寻呼机制的前提。因此，如何使终端设备和网络设备对于终端设备寻呼能力具有一致的认识，进而可正常使用基于终端设备寻呼能力的寻呼机制， 以提高寻呼可靠性成为当前亟待解决的问题之一。
基于此，本申请实施例提供了一种通信方法及相关装置，能够使得终端设备和网络设备对于终端设备寻呼能力具有一致的认识，提高寻呼可靠性。
需要说明的是，本申请实施例中“特性”可以理解为机制或功能，本申请实施例中的“能力”可以理解为包括但不限于寻呼能力。其中，特性可以有对应的终端设备能力，该终端设备能力用于指示终端设备是否支持该特性。
下面对本申请提供的通信方法及相关装置进行详细介绍：
请参见图4，图4是本申请实施例提供的通信方法的一流程示意图。如图4所示，该通信方法包括如下步骤S400～S402。图4所示的方法执行主体可以为终端设备或接入网设备。或者，图4所示的方法执行主体可以为终端设备或接入网设备中的芯片，以下本申请实施例以终端设备和接入网设备为例进行示意性说明。其中：
S401、终端设备向接入网设备发送寻呼能力信息。
相应地，接入网设备接收来自终端设备的寻呼能力信息。其中，寻呼能力信息用于指示终端设备支持的一项或多项寻呼能力，可以理解为：终端设备通过寻呼能力信息向接入网设备上报终端设备的寻呼能力。示例性地，寻呼能力包括以下一项或多项：PEI能力，PO标识计算能力，接收天线通道数能力，半双工能力，下行调度能力或支持频带能力等，在此不做限制。其中，针对上述各项寻呼能力的理解可参见前述终端设备寻呼能力上报与维护的描述中的相关描述，在此不进行赘述。
这里，寻呼能力信元可以是UERadioPagingInformation，通常来说，寻呼能力信元可以携带在UERadioPagingInformation message中。
可选地，在步骤S401之前，还可以包括如下步骤S400：
S400、接入网设备向终端设备发送能力查询消息。
相应地，终端设备接收来自接入网设备的能力查询消息。这里，能力查询消息用于请求终端设备上报能力，可以理解为：能力查询消息用于触发终端设备向接入网设备发送寻呼能力信息。因此，终端设备可以根据接收到的能力查询消息向接入网设备发送寻呼能力信息。这里，能力查询消息具体可以是终端设备能力查询消息(例如，UECapabilityEnquiry消息)等，在此不做限制。
其中，步骤S400可以是核心网设备触发接入网设备进行终端设备寻呼能力查询，例如，核心网设备向接入网设备发送指示信息，用于指示接入网设备请求终端设备上报终端设备的寻呼能力。或者，步骤S400可以是接入网设备主动进行终端设备寻呼能力查询，这里，接入网设备有可能由于未收到终端设备的寻呼能力信息而进行主动查询，例如，当接入网设备未从核心网设备接收到终端设备的寻呼能力信息时，接入网设备可以主动请求终端设备上报终端设备的寻呼能力。或者，步骤S400可以是终端设备触发终端设备寻呼能力上报流程，以使核心网设备触发接入网设备进行终端设备寻呼能力查询，例如，终端设备向核心网设备发送指示信息1，用于指示终端设备需要更新终端设备的寻呼能力信息(该指示信息1可携带在移动性注册请求消息中)，核心网设备向接入网设备发送指示信息2，用于指示接入网设备请求终端设备上报终端设备的寻呼能力。或者，步骤S400可以是终端设备触发终端设备寻呼能力上报流程，以使接入网设备进行终端设备寻呼能力查询，例如，终端设备向接入网设备发送指示信息，用于指示终端设备需要更新终端设备的能力信息。
S402、接入网设备向终端设备发送第一信息。
相应地，终端设备接收来自接入网设备的第一信息。其中，第一信息用于指示接入网设备成功维护寻呼能力信息所指示的该一项或多项寻呼能力，可以理解为：第一信息用于指示接入网设备成功维护终端设备上报的所有寻呼能力，即，将该一项或多项寻呼能力作为整体进行指示。这里，第一信息也可以用于指示接入网设备是否成功维护寻呼能力所指示的该一项或多项寻呼能力，若网络设备成功维护终端设备上报的所有寻呼能力，则第一信息指示成功维护该一项或多项寻呼能力，其余情况均视为未成功维护该一项或多项寻呼能力。或者，第一信息用于指示接入网设备成功维护的至少一项寻呼能力，该至少一项寻呼能力为寻呼能力信息所指示的该一项或多项寻呼能力中的至少一项，可以理解为：第一信息用于指示终端设备上报的寻呼能力之中被接入网设备成功维护的寻呼能力。这里，成功维护可以理解为已维护。
需要说明的是，接入网设备接收到寻呼能力信息之后，接入网设备可以解析该寻呼能力信息，以得到寻呼能力信息所指示的一项或多项寻呼能力。进一步地，接入网设备可以根据解析出的一项或多项寻呼能力生成寻呼能力信元(例如，在寻呼能力信元中添加解析出的一项或多项寻呼能力)，并发送至核心网 设备，或者在发起接入网寻呼时将该寻呼能力信元发送至其他接入网设备。这里，解析也可以理解为解读或处理。
相应地，接入网设备成功维护一项或多项寻呼能力可以理解为：接入网设备已解析出一项或多项能力信息，接入网设备已根据解析出的一项或多项寻呼能力生成寻呼能力信元，或者接入网设备已将包含解析出的一项或多项寻呼能力的寻呼能力信元发送至核心网设备或其他接入网设备。通常来说，如果接入网设备支持某个特性，则可以视为接入网设备能够维护该特性对应的寻呼能力。另一方面，即使接入网设备不支持某个特性，也并不意味着接入网设备一定无法成功维护该特性对应的寻呼能力。
具体地，第一信息可以包括一个或多个第一指示信息和/或一个或多个第二指示信息，第一指示信息用于指示接入网设备成功维护一项寻呼能力，第二指示信息用于指示接入网设备成功维护多项寻呼能力。也就是说，一个指示信息可以对应一项或多项寻呼能力。这里，第二指示信息所指示的多项寻呼能力(可以理解为第二指示信息与该多项寻呼能力之间的对应关系)是协议预定义的，或者是由接入网设备配置的，或者是预配置的。
例如，协议可以预定义：第一指示信息1对应PEI能力，第一指示信息2对应PO标识计算能力，第二指示信息1对应天线通道数能力和半双工能力，第二指示信息2对应下行调度能力和支持频带能力。这里，不同的指示信息可以携带在同一或不同的消息中发送给终端设备。例如，第一信息包括第一指示信息1和第二指示信息1，第一指示信息1和第二指示信息1可以被携带在同一消息中，也可以被携带在不同的消息中。这种情况下，作为示例，终端设备上报了上述第一指示信息1、第一指示信息2、第二指示信息1和第二指示信息2所对应的全部寻呼能力，但接入网设备仅成功维护终端设备上报的PEI能力、天线通道数能力和半双工能力。因而，接入网设备向终端设备发送第一指示信息1和第二指示信息1，分别用于通知终端设备：接入网设备成功维护终端设备上报的PEI能力；接入网设备成功维护终端设备上报的天线通道数能力和半双工能力。
可选地，终端设备后续可以根据接入网设备的第一信息，确定接入网设备是否成功维护终端设备上报的寻呼能力，进而确定如何进行寻呼相关操作。例如，若终端设备接收到接入网设备的第一信息，则终端设备确认接入网设备成功维护该第一信息对应的寻呼能力，如果该第一信息对应的寻呼能力并非是终端设备上报的寻呼能力的全部，其余寻呼能力被认为未被接入网设备成功维护。又例如，若终端设备在一段时间内或在某个流程前未接收到接入网设备的第一信息，则终端设备确认接入网设备未成功维护终端设备上报的寻呼能力。如果终端设备确认接入网设备成功维护某项或某些寻呼能力，则终端设备认为已成功上报该寻呼能力，后续可使用该寻呼能力对应的机制。如果终端设备确认接入网设备未成功维护某项或某些寻呼能力，则终端设备认为未成功上报该寻呼能力，后续不使用该寻呼能力对应的机制。
举例来说，若终端设备接收到接入网设备针对PEI能力的第一信息，则终端设备认为终端设备上报的PEI能力已被处理，后续可使用PEI机制。其中，终端设备使用PEI机制的条件可以是以下一项或多项：终端设备驻留的小区支持PEI特性(即，当前小区在***信息中发送了PEI相关配置信息)，终端设备支持当前小区所使用的终端设备分组机制。
在本申请实施例中，为使得终端设备和网络设备对于终端设备寻呼能力具有一致的认识，终端设备从接入网设备接收指示终端设备上报的寻呼能力被成功维护的第一信息，这里可以理解为：接入网设备针对终端设备寻呼能力的上报进行了确认。通过这种方式，终端设备可以确定出接入网设备是否成功维护终端设备上报的寻呼能力，从而与网络设备对于终端设备寻呼能力具有一致的认识，提高寻呼可靠性。例如，这种方式可以使得终端设备确定后续在寻呼相关的操作中是否可使用这些寻呼能力对应的机制，避免终端设备和接入网设备采用不同的寻呼操作，保证终端设备可以正常接收到接入网设备的寻呼。
请参见图5，图5是本申请实施例提供的通信方法的另一流程示意图。如图5所示，该通信方法包括如下步骤S501～S502。图5所示的方法执行主体可以为终端设备或接入网设备。或者，图5所示的方法执行主体可以为终端设备或接入网设备中的芯片，以下本申请实施例以终端设备和接入网设备为例进行示意性说明。其中：
S501、接入网设备向终端设备发送第二信息。
相应地，终端设备接收来自接入网设备的第二信息。其中，第二信息用于指示接入网设备请求的一项或多项寻呼能力，可以理解为：接入网设备请求终端设备上报指定的终端设备寻呼能力。针对寻呼能力的理解可参见图4对应的方法实施例中的相关描述，在此不进行赘述。
具体地，第二信息可以包括一个或多个第三指示信息和/或一个或多个第四指示信息。其中第三 指示信息用于指示接入网设备请求的一项或多项寻呼能力，第四指示信息用于指示接入网设备请求的一个或多个寻呼能力字段，其中寻呼能力字段对应一项或多项寻呼能力。需要说明的是，寻呼能力字段所对应的一项或多项寻呼能力可以理解为：允许包括在寻呼能力字段中的一项或多项寻呼能力，寻呼能力字段实际包括的寻呼能力可以为所有允许包括在该寻呼能力字段中的寻呼能力，也可以是其中的一部分。寻呼能力字段所对应的一项或多项寻呼能力(即，哪些寻呼能力可以放入该寻呼能力字段中)可以是协议预定义的，或者是由接入网设备配置的，或者是预配置的。
具体地，第三指示信息、第四指示信息可以是终端设备寻呼能力相关的过滤器。其中，第三指示信息可以是针对寻呼能力的过滤器，这里，针对寻呼能力可以理解为：直接针对一项或多项寻呼能力，或者针对某个或某些特性，该特性对应一项或多项寻呼能力。例如，第三指示信息1为针对PEI能力的过滤器，第三指示信息2为针对PO标识计算能力的过滤器。再例如，第三指示信息1为针对PEI能力和PO标识计算能力的过滤器，第三指示信息2为针对RedCap特性的过滤器，该特性对应天线通道数能力和半双工能力。第四指示信息可以是针对寻呼能力字段的过滤器。例如，第四指示信息1为针对寻呼能力字段1的过滤器，寻呼能力字段1对应PEI能力。再例如，第四指示信息2为针对寻呼能力字段2的过滤器，寻呼能力字段2对应接收天线通道数能力和半双工能力。
在一种实现中，第二信息可携带于接入网设备发送的能力查询消息中，也就是说，接入网设备向终端设备发送能力查询消息，相应地，终端设备接收来自接入网设备的能力查询消息，能力查询消息中包括第二信息。其中，针对能力查询消息的理解(包括其触发方式)可参见图4对应的方法实施例中的相关描述，在此不进行赘述。
在另一种实现中，第二信息也可以携带在除能力查询消息之外的其他消息中发送给终端设备，也就是说，接入网设备可以向终端设备分别发送能力查询消息和第二信息，其中，能力查询消息用于请求终端设备上报能力，第二信息用于指示接入网设备请求的一项或多项寻呼能力。因此，终端设备接收到来自接入网设备的能力查询消息和第二信息之后，可基于第二信息和能力查询消息向接入网设备发送寻呼能力信息。
本申请实施例主要以第二信息携带于能力查询消息发送为例进行理解。
S502、终端设备基于第二信息向接入网设备发送寻呼能力信息。
相应地，接入网设备接收来自终端设备的寻呼能力信息。其中，寻呼能力信息指示终端设备支持的至少一项寻呼能力，该至少一项寻呼能力为第二信息所指示的该一项或多项寻呼能力中的至少一项，可以理解为：寻呼能力信息用于上报接入网设备请求的寻呼能力之中终端设备所支持的寻呼能力。也就是说，终端设备上报的寻呼能力未超出接入网所请求的寻呼能力的范围，而接入网所请求的寻呼能力不会超出接入网设备能够维护的寻呼能力的范围，因此，可保证终端设备所上报的寻呼能力能够被接入网设备成功维护。在第二信息包括接入网设备请求的寻呼能力字段的指示信息的情况下，终端设备可以上报接入网设备所请求的寻呼能力字段，该寻呼能力字段包括终端设备支持的一项或多项寻呼能力。需要说明的是，寻呼能力字段所包括的一项或多项寻呼能力可以理解为：实际包括(即，承载)在该寻呼能力字段中的寻呼能力。
需要说明的是，接入网设备向终端设备发送第二信息，则表明请求终端设备上报第二信息所指示的一项或多项寻呼能力。例如，接入网设备发送第二信息1，第二信息1用于指示PEI能力，则表明接入网设备请求终端设备上报PEI能力，若终端设备支持PEI能力，就需要进行上报，若终端设备不支持PEI能力，则不上报。又例如，接入网设备发送第二信息2，第二信息2用于指示上述寻呼能力字段2(其对应接收天线通道数能力和半双工能力)，则表明接入网设备请求终端设备上报寻呼能力字段2对应的寻呼能力，若终端设备支持这两种能力，则终端设备通过寻呼能力字段2上报接收天线通道数能力和半双工能力，其中；若终端设备支持接收天线通道数能力但不支持半双工能力，则终端设备通过寻呼能力字段2上报接收天线通道数能力；若终端设备不支持这两种能力，则不上报。
可以理解为，在接入网设备能够维护终端设备的某种寻呼能力的情况下，接入网设备可向终端设备发送相应的第二信息请求终端设备上报这种寻呼能力。其中，针对能够维护的理解可参见图4对应的方法实施例中对于成功维护的相关描述(能够维护可以理解为具有成功维护的能力)，在此不进行赘述。例如，接入网设备能够维护PEI能力，因而向终端设备发送上述第二信息1(用于指示PEI能力)，这里，接入网设备本身可以支持PEI特性，也可以不支持PEI特性。
可选地，若终端设备在步骤S502中根据接入网设备发送的第二信息上报了终端设备支持的寻呼能力， 则终端设备即可确定已成功上报终端设备的寻呼能力(即，正常情况下，终端设备上报的寻呼能力会被接入网设备成功维护)，进而确定如何进行寻呼相关操作。例如，若终端设备上报了某项或某些寻呼能力，则终端设备后续可使用该寻呼能力对应的机制，且不使用未上报的寻呼能力对应的机制。
可选地，接入网设备接收到寻呼能力信息之后，接入网设备可以解析该寻呼能力信息，以得到寻呼能力信息所指示的终端设备支持的至少一项寻呼能力。进一步地，接入网设备可以根据解析出的至少一项寻呼能力生成寻呼能力信元，并向核心网设备发送寻呼能力信元，或者在发起接入网寻呼时发送至其他接入网设备。
举例来说，假设终端设备接收到接入网设备指示请求PEI能力的第二信息，且终端设备向接入网设备上报了终端设备的PEI能力，则终端设备认为终端设备上报的PEI能力能够被接入网设备成功维护，后续可使用PEI机制。
在本申请实施例中，为使终端设备和网络设备对于终端设备寻呼能力具有一致的认识，接入网设备通过第二信息请求寻呼能力的，终端设备根据第二信息上报终端设备支持的寻呼能力，这里可以理解为：终端设备向接入网设备上报接入网设备所请求的寻呼能力之中被终端设备支持的寻呼能力。通过这种方式，终端设备可以确定所上报的寻呼能力能够被网络设备成功维护，从而与网络设备对于终端设备寻呼能力具有一致的认识，提高寻呼可靠性。例如，这种方式可以使得终端设备获知接入网设备所请求的寻呼能力是能够被接入网设备成功维护的寻呼能力，因而，终端设备成功完成接入网设备所请求的寻呼能力中终端设备所支持的寻呼能力的上报后，终端设备即可确定所上报的寻呼能力能够被接入网设备成功维护，进而确定后续在寻呼相关的操作中可使用这些寻呼能力对应的机制，避免终端设备和接入网设备采用不同的寻呼操作，保证终端设备可以正常接收到接入网设备的寻呼。
请参见图6，图6是本申请实施例提供的通信方法的另一流程示意图。如图6所示，该通信方法包括如下步骤S601～S602。图6所示的方法执行主体可以为终端设备或接入网设备。或者，图6所示的方法执行主体可以为终端设备或接入网设备中的芯片，以下本申请实施例以终端设备和接入网设备为例进行示意性说明。其中：
S601、接入网设备向终端设备发送第三信息。
相应地，终端设备接收来自接入网设备的第三信息。其中，第三信息用于指示接入网设备能够维护的一项或多项寻呼能力，可以理解为：接入网设备将其对于终端设备寻呼能力的维护能力告知终端设备。其中，针对寻呼能力的理解可参见图4对应的方法实施例中的相关描述，针对能够维护的理解可参见图4对应的方法实施例中对于成功维护的相关描述(能够维护可以理解为具有成功维护的能力)，在此不进行赘述。
其中，第三信息包括以下一项或多项：一个或多个第五指示信息，一个或多个第六指示信息，一个或多个第七指示信息，一个或多个第八指示信息。其中，第五指示信息用于指示一项或多项寻呼能力。第六指示信息用于指示一个或多个寻呼能力字段，寻呼能力字段对应一项或多项寻呼能力。第七指示信息用于指示一个或多个特性，特性对应一项或多项寻呼能力；或者，第八指示信息用于指示一个或多个协议版本，协议版本对应一项或多项寻呼能力。可以理解为：第三信息指示接入网设备能够维护的一项或多项寻呼能力的具体方式可以包括如下四种：1、第三信息直接包括接入网设备能够维护的寻呼能力；2、第三信息直接包括接入网设备能够维护的寻呼能力字段；3、第三信息直接包括接入网设备支持的特性；4、第三信息直接包括接入网设备支持的协议版本。其中，接入网设备能够维护的一项或多项寻呼能力是特性对应的寻呼能力，接入网设备能够维护的一项或多项寻呼能力是协议版本支持的寻呼能力。
这里，上述第三信息可以是广播发送的，也可以是使用专用信令发送给终端设备的。具体地，第三信息可承载于DCI、***信息、RRC消息等，在此不做限制。
例如，若接入网设备能够维护PEI能力，则接入网设备可以发送第三信息1，第三信息1包括PEI能力的指示信息，使得终端设备可获知接入网设备能够维护PEI能力。又例如，若接入网设备能够维护PEI能力，则接入网设备可以发送第三信息2，第三信息2包括前述寻呼能力字段1(其对应PEI能力)的指示信息，使得终端设备可获知接入网设备能够维护PEI能力。再例如，若接入网设备支持RedCap特性，则接入网设备发送第三信息3，第三信息3包括RedCap特性的指示信息，该特性对应天线通道数能力和半双工能力，使得终端设备可获知接入网设备能够维护天线通道数能力和半双工能力。还例如，若接入网设备能够维护版本17(Release 17，R17)的协议版本对应的寻呼能力，则 接入网设备可以发送第三信息4，第三信息4包括R17的指示信息，使得终端设备可获知接入网设备能够维护R17对应的寻呼能力，这里，接入网设备可以支持R17的特性，也可以不支持R17的特性，但能够维护R17的特性对应的寻呼能力，如果接入网设备支持多个版本，可以指示其支持的最高版本。
可选地，第三指示信息也可以与其他信息结合使用。例如，若接入网设备支持PEI特性但未使能PEI机制(即，接入网设备没有启用或使用PEI机制)，因而不会发送PEI的配置信息，则接入网设备发送第三信息；若接入网设备支持PEI特性且已使能PEI机制(即，接入网设备启用或使用了PEI机制)，则接入网设备发送PEI的配置信息，此时，接入网设备可以发送也可以不发送第三信息。这里，PEI的配置信息用于配置PEI，例如，PEI的配置信息可以用于配置PEI的监听时机，或者用于配置发送PEI的时频资源等，在此不做限制。
可选地，接入网设备除了向终端设备发送第三信息，还可以向终端设备发送能力查询消息，即第三信息独立于能力查询消息发送。相应地，终端设备接收来自接入网设备的第三信息和能力查询消息。其中，针对能力查询消息的理解(包括其触发方式)可参见图4对应的方法实施例中的相关描述，在此不进行赘述。因此，终端设备可以基于第三信息和能力查询消息向接入网设备发送寻呼能力信息，也就是说，终端设备可以基于能力查询消息的触发，再根据第三信息指示的接入网设备能够维护的寻呼能力向接入网设备发送寻呼能力信息。
可选地，第三信息也可以携带于接入网设备发送的能力查询消息中，也就是说，接入网设备向终端设备发送能力查询消息，相应地，终端设备接收来自接入网设备的能力查询消息，能力查询消息中包括第三信息。
本申请实施例主要以第三信息独立于能力查询消息发送为例进行理解。
S602、终端设备基于第三信息向接入网设备发送寻呼能力信息。
相应地，接入网设备接收来自终端设备的寻呼能力信息。其中寻呼能力信息指示终端设备支持的至少一项寻呼能力，该至少一项寻呼能力为第三信息所指示的该一项或多项寻呼能力中的至少一项，可以理解为：寻呼能力信息用于上报接入网设备能够维护的寻呼能力之中终端设备所支持的寻呼能力。也就是说，终端设备上报的寻呼能力未超出接入网能够维护的寻呼能力的范围，因此，可保证终端设备所上报的寻呼能力能够被接入网设备成功维护。
需要说明的是，接入网设备向终端设备发送第三信息，仅表明接入网设备有能力维护第三信息所指示的一项或多项寻呼能力，并不代表请求终端设备上报该一项或多项寻呼能力，可以理解为若该一项或多项寻呼能力中的任意寻呼能力被终端设备支持，则终端设备可以选择上报该支持的寻呼能力，也可以选择不上报。
例如，若终端设备接收到第三信息5，第三信息5包括PEI特性的指示信息，该特性对应PEI能力，若终端设备支持PEI能力，则终端设备上报PEI能力。再例如，若终端设备接收到前述的第三信息2(其包括前述的寻呼能力字段1的指示信息，寻呼能力字段1对应PEI能力)，若终端设备支持PEI能力，则终端设备可以使用寻呼能力字段1上报PEI能力。又例如，若终端设备接收到的第三信息6，第三信息6包括版本15(Release 15，R15)的指示信息，R15对应的寻呼能力不包括PEI能力，即使终端设备支持PEI能力，也不会上报PEI能力。
可选地，若终端设备在步骤S602中根据接入网设备发送的第三信息上报了终端设备支持的寻呼能力，则终端设备即可确定已成功上报终端设备的寻呼能力，进而确定如何进行寻呼相关操作。例如，若终端设备上报了某项或某些寻呼能力，则终端设备后续可使用该寻呼能力对应的机制，且不使用未上报的寻呼能力对应的机制。
可选地，若终端设备在步骤S602中根据接入网设备发送的第三信息，上报了终端设备支持的寻呼能力，则终端设备即可确定已成功上报终端设备的寻呼能力，进而确定如何进行寻呼相关操作。例如，若终端设备上报了某个或某些寻呼能力，则终端设备后续可使用该寻呼能力对应的机制，且不使用未上报的寻呼能力对应的机制。
可选地，接入网设备接收到寻呼能力信息之后，接入网设备可以解析该寻呼能力信息，以得到寻呼能力信息所指示的终端设备支持的一项或多项寻呼能力。进一步地，接入网设备可以根据解析出的一项或多项寻呼能力生成寻呼能力信元，并发送至核心网设备，或者在发起接入网寻呼时发送至其他接入网设备。
举例来说，假设终端设备接收到接入网设备指示能够维护PEI能力的第三信息，且终端设备向接入网设备上报了终端设备的PEI能力，则终端设备认为终端设备上报的PEI能力已被处理，后续可使用PEI机 制。
在本申请实施例中，为使终端设备和网络设备对于终端设备寻呼能力具有一致的认识，接入网设备通过第三信息告知其能够维护的寻呼能力，终端设备根据第三信息上报终端设备支持的寻呼能力，这里可以理解为：终端设备向接入网设备上报接入网设备能够维护的寻呼能力之中被终端设备支持的寻呼能力。通过这种方式，终端设备可以确定所上报的寻呼能力能够被网络设备成功维护，从而与网络设备对于终端设备寻呼能力具有一致的认识，提高寻呼可靠性。例如，这种方式可以使得终端设备获知接入网设备能够成功维护哪些寻呼能力，因而，终端设备可相应地进行终端设备的寻呼能力上报，成功完成接入网设备所请求的寻呼能力中终端设备所支持的寻呼能力的上报后，终端设备即可确定所上报的寻呼能力能够被接入网设备成功维护，进而确定后续在寻呼相关的操作中可使用这些寻呼能力对应的机制，避免终端设备和网络设备采用不同的寻呼操作，保证终端设备可以正常接收到网络设备的寻呼。
请参见图7，图7是本申请实施例提供的通信方法的另一流程示意图。如图7所示，该通信方法包括如下步骤S700～S703。图7所示的方法执行主体可以为终端设备或接入网设备。或者，图7所示的方法执行主体可以为终端设备或接入网设备中的芯片，以下本申请实施例以终端设备和接入网设备为例进行示意性说明。其中：
S701、终端设备确定寻呼能力信元。
该寻呼能力信元也可称为容器。该寻呼能力信元中包含终端设备支持的一项或多项寻呼能力。其中，针对寻呼能力的理解可参见图4对应的方法实施例中的相关描述，在此不进行赘述。寻呼能力信元允许包括的一项或多项寻呼能力(即，哪些寻呼能力可以放入该寻呼能力信元中)可以是协议规定的，或者由接入网设备配置的，或者是预配置的。
S702、终端设备向接入网设备发送寻呼能力信元。
相应地，接入网设备接收来自终端设备的寻呼能力信元。
这里，若终端设备在步骤S702中上报了寻呼能力相关的寻呼能力信元，则终端设备即可确定已成功上报该寻呼能力信元包含的能力，进而确定如何进行寻呼相关操作。例如，若终端设备上报了包括某个或某些寻呼能力的寻呼能力信号，则终端设备后续可使用该寻呼能力对应的机制，且不使用未上报的寻呼能力对应的机制。
可选地，在步骤S702之前，还可以包括如下步骤S700：
S700、接入网设备向终端设备发送能力查询消息。
相应地，终端设备接收来自接入网设备的能力查询消息，因此终端设备可以根据接收到的能力查询消息向接入网设备发送寻呼能力信息。其中，针对能力查询消息的理解(包括其触发方式)可参见图4对应的方法实施例中的相关描述，在此不进行赘述。
S703、接入网设备向核心网设备发送寻呼能力信元。
这里，可以理解为接入网设备直接发送所接收到的寻呼能力信元，也就是说，接入网设备可以将终端设备上报的寻呼能力信元转发至核心网设备。相应地，核心网设备接收并保存来自接入网设备的寻呼能力信元。这里，“转发”意味着接入网设备本身不需要对寻呼能力信元进行二次处理(例如进一步的解析处理)。
可选地，接入网设备也可以在发起接入网寻呼时，将寻呼能力信元转发至其他接入网设备。
举例来说，假设终端设备向接入网设备上报了包含PEI能力的寻呼能力信元，则终端设备认为终端设备上报的PEI能力已被处理，后续可使用PEI机制。
在本申请实施例中，为使终端设备和网络设备对于终端设备寻呼能力具有一致的认识，终端设备向接入网设备上报寻呼能力信元，以供接入网设备将该寻呼能力信元发送给核心网设备，这里可以理解为：接入网设备直接转发从终端设备接收的寻呼能力信元，而不需要由接入网设备对终端设备上报的寻呼能力进行二次处理以生成寻呼能力信元再发送给核心网设备。通过这种方式，终端设备可以确定通过寻呼能力信元上报的寻呼能力能够被网络设备成功维护，从而与网络设备对于终端设备寻呼能力具有一致的认识，提高寻呼可靠性。例如，这种方式可以使得终端设备在成功完成终端设备能力上报流程后，即可确定上报的寻呼能力能够被网络设备成功维护，进而确定后续在寻呼相关的操作中可使用这些能力对应的机制，避免终端设备和网络设备采用不同的寻呼操作，保证终端设备可以正常接收到网络设备的寻呼。
应理解，在上文实施例中，终端设备和/或接入网设备可以执行各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，各个步骤可以按照各实施例呈现的不同的顺序来执行，并且有可能并非要执行本申请实施例中的全部操作。且，各步骤的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
应理解，本申请中某个实施例包括的一个或多个步骤也可以与其他实施例中的一个或多个步骤结合使用，在此不做限制。此外，本申请的各个实施例中类似的步骤或术语可以相互参照进行理解，不应由于某些描述仅出现在单个实施例中就认为该描述无法适用于其他实施例。
