Description

一种通信方法及装置
相关申请的交叉引用
本申请要求在2020年05月15日提交中国国家知识产权局、申请号为202010415378.3、申请名称为“一种通信方法及装置”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装置。
背景技术
终端设备会在寻呼时机(paging occasion，PO)内监听寻呼调度，并根据寻呼调度检测寻呼消息，PO是寻呼帧(paging frame，PF)中的一个特殊子帧，终端设备确定PF后通过查表就可以确定PO。目前终端设备是通过终端设备的身份号(ID)以及相应的配置来确定PF，可能有多个终端设备所确定的PF是同一个PF，进而可能多个终端设备所确定的PO是同一个PO。
另外，为了减少终端监听寻呼调度和检测寻呼消息的功耗，在每个PO之前引入了唤醒信号(wake up signal，WUS)。只有终端设备在PO前检测到了WUS，才需要按照传统的方式在相应的PO监听物理下行控制信道(physical downlink control channel，PDCCH)，进而监听寻呼消息。
根据前文介绍可知，很可能存在多个终端设备对应同一个PO的情况，那么就会存在寻呼虚警的问题。例如，一个小区中有100个终端设备确定的PO是同一个PO，则这100个终端设备都会监听该PO或监听该PO对应的WUS。如果基站要寻呼这100个终端设备中的其中一个或几个终端设备，都需要在该PO前发送相应的WUS。在这种情况下，其他未被寻呼的终端设备也会监听到WUS，并因此被唤醒进而监听PDCCH和寻呼消息，这就是所谓的寻呼虚警。对于未被寻呼的终端设备来说，在WUS之后监听PDCCH以及寻呼消息等，是没有意义的，只会带来额外的功率损耗。
发明内容
本申请实施例提供一种通信方法及装置，用于减少寻呼导致的终端设备的功耗。
第一方面，提供第一种通信方法，该方法包括：接收来自核心网设备的第一寻呼消息，所述第一寻呼消息包括第一终端设备的标识，以及，所述第一寻呼消息还指示所述第一终端设备所属的第一分组；确定所述第一分组对应的第二分组；按照所述第二分组对应的第一寻呼方式寻呼所述第一终端设备。
该方法可由第一通信装置执行，第一通信装置可以是通信设备或能够支持通信设备实现该方法所需的功能的通信装置，例如芯片。示例性地，所述第一通信装置为网络设备，或者为设置在网络设备中的用于实现网络设备的功能的芯片，或者为用于实现网络设备的功能的其他部件。在下文的介绍过程中，以第一通信装置是网络设备为例。示例性地，所 述网络设备为接入网设备，例如基站。
在本申请实施例中，将终端设备进行了分组，对不同分组的终端设备可采用不同的寻呼方式。对于一个终端设备来说，如果通过监听确定寻呼方式不是该终端设备所在的分组的寻呼方式，那么该终端设备就可以不必监听寻呼消息等，通过这种方式可以节省终端设备的功耗，减小虚警的概率。
而且，接入网设备可以不必局限于核心网设备的分组，而是可以自行设置新的分组，只需建立两种分组方式的映射关系即可，对于接入网设备的限制较小。而且，如果核心网设备的分组粒度较细，例如核心网设备是按照寻呼概率参数对应的概率值来分组，核心网设备按照5％为粒度来划分，则核心网设备可以划分20组。如果接入网设备未自行设置新的分组，则需要为这20组分别配置寻呼方式，接入网设备可能并不支持这么多种寻呼方式。在本申请实施例中，接入网设备可以再按照第二分组方式来分组，例如接入网设备也按照寻呼概率参数对应的概率值来分组，但接入网设备按照25％为粒度来划分，则核心网设备可以划分4组，且接入网设备可以建立两种分组方式的映射关系。从而接入网设备只需支持较少的寻呼方式即可完成寻呼，较为灵活，且对于核心网设备所划分的每个分组包括的终端设备，接入网设备都能确定对应的寻呼方式。
在一种可选的实施方式中，所述第一寻呼消息指示所述第一终端设备所属的第一分组，包括：
所述第一寻呼消息包括所述第一分组的信息；或，
所述第一寻呼消息不包括所述第一终端设备所属的分组的信息。
第一寻呼消息指示第一分组可以包括不同的情况。例如一种情况为，第一消息寻呼包括第一分组的信息，在这种情况下，第一分组是第一分组方式下的一个分组。例如，核心网设备确定了第一终端设备在第一分组方式下属于第一分组，则核心网设备可以将第一分组的信息包括在第一寻呼消息中。又例如，另一种情况为，第一寻呼消息不包括第一终端设备所属的分组的信息，在这种情况下，第一分组视为默认分组(例如称为第二默认分组)，即，在第一分组方式下不属于任何分组的终端设备，都可以认为属于第一分组。例如，核心网设备未确定第一终端设备在第一分组方式下所属的分组，或者核心网设备确定第一终端设备在第一分组方式下不属于任何分组，则第一寻呼消息中不包括第一终端设备所属的分组的信息。通过本申请实施例提供的方式，即使核心网设备未确定第一终端设备在第一分组方式下所属的分组，或者核心网设备确定第一终端设备在第一分组方式下不属于任何分组，也可以认为第一终端设备属于第一分组(第二默认分组)，从而对于各个终端设备都能够划分到相应的分组。
在一种可选的实施方式中，所述第一寻呼消息包括所述第一分组的信息，确定所述第一分组对应的第二分组，包括：
根据所述第一分组与所述第二分组的映射关系，确定所述第二分组。
如果第一寻呼消息包括第一分组的信息，且第一分组方式与第二分组方式之间的映射关系中包括第一分组的信息，则接入网设备可以确定该映射关系中第一分组对应的第二分组，即，确定第一终端设备在第二分组方式下对应第二分组。
在一种可选的实施方式中，所述第一寻呼消息不包括所述第一分组的信息，确定所述第一分组对应的第二分组，包括：
根据所述第一分组与所述第二分组的映射关系，确定所述第一终端设备不对应任何分 组；
确定所述第二分组。
例如，第一寻呼消息包括第一分组的信息，且第一分组方式与第二分组方式之间的映射关系中不包括第一分组的信息，则接入网设备可以确定第一分组对应的第二分组。或者，第一寻呼消息不包括第一终端设备在第一分组方式下所属的分组的信息，也可以认为第一终端设备在第一分组方式下属于第一分组。如果是这种情况，则接入网设备也可以确定第一终端设备对应于第二分组。
在一种可选的实施方式中，
所述第二分组为默认分组；或，
确定所述第一分组对应于所述第二分组，包括：根据第二参数确定所述第一终端设备属于所述第二分组。
例如第二分组为第一默认分组，所谓的第一默认分组可以理解为，对于无法对应到该映射关系的终端设备，都认为属于第一默认分组，第一默认分组可以对应默认寻呼方式，或者称为缺省寻呼方式。第一默认分组对应的默认寻呼方式例如可通过协议规定，或者可以预配置在接入网设备和终端设备中。或者，接入网设备可以根据第二参数确定第一终端设备所属的分组，即，虽然在该映射关系中不存在与第一分组对应的任何分组，接入网设备还是可以确定第一终端设备在第二分组方式下所属的分组，例如接入网设备根据第二参数确定第一终端设备属于第二分组，从而接入网设备可以按照第二分组对应的寻呼方式监听寻呼控制信息。通过这种类似于“回退”的方式，可以使得更多的终端设备能够被寻呼。
在一种可选的实施方式中，按照所述第二分组对应的第一寻呼方式寻呼所述第一终端设备，包括：
发送所述第二分组对应的第一寻呼控制信息，以寻呼所述第一终端设备。
在本申请实施例中，不同的寻呼方式可以对应不同的寻呼控制信息，或者理解为，接入网设备发送的寻呼控制信息不同，就是使用了不同的寻呼方式。例如，寻呼方式1对应寻呼控制信息1，寻呼方式2对应寻呼控制信息2，等等。寻呼控制信息例如为WUS(或者称为WUS序列)，或者例如为用于调度寻呼消息的PDCCH(或者说是DCI)。当然寻呼控制信息还可以是其他的信息，具体的不做限制。
在一种可选的实施方式中，
所述第一寻呼控制信息为所述第二分组对应的第一WUS序列；或，
所述第一寻呼控制信息为第一DCI，所述第一DCI通过所述第二分组对应的第一RNTI加扰；或，
所述第一寻呼控制信息为第一DCI，所述第一DCI包括第一比特地图，所述第一比特地图中对应于所述第二分组的比特的取值为第一值；或，
所述第一寻呼控制信息为第一DCI，所述第一DCI包括所述第二分组的标识。
如果寻呼控制信息为WUS序列，那么寻呼控制信息不同，可以是指WUS序列不同(这里可以理解为构成WUS序列的码字不同)，或者也可以是指WUS序列的资源位置不同，WUS序列的资源位置，例如包括如下的一种或多种：WUS序列的时域资源位置，WUS序列的频域资源位置，或，WUS序列的码域资源位置。
或者，如果寻呼控制信息为DCI，那么寻呼控制信息不同，可以是指DCI所包括的子映射关系的信息不同，或者是指用于加扰DCI的RNTI不同。如果DCI不同是指DCI所 包括的子映射关系的信息不同，或者说，是指DCI所包括的分组的信息不同，这里的分组，指的是第二分组方式下的分组。DCI所包括的分组的信息可以包括bitmap，或者也可以包括分组的标识(例如分组的ID)，或者也可以包括bitmap和分组的标识。例如分组的信息包括bitmap，则DCI可以包括第一bitmap，第一bitmap可包括一个或多个比特，其中的每个比特对应第二分组方式下的一个分组或多个分组。如果第一bitmap中的一个比特的取值为第一值，则表明该比特所对应的一个或多个分组被寻呼，或者说，是表明该比特所对应的一个或多个分组所包括的终端设备被寻呼。又例如，分组的信息包括分组的标识，那么，如果一个DCI包括第二分组的标识，则表明第二分组所包括的终端设备被寻呼，而如果一个DCI不包括第二分组的标识，则表明第二分组包括的终端设备未被寻呼。
在一种可选的实施方式中，所述方法还包括：
发送广播消息，所述广播消息包括所述第一分组的标识，以及包括所述第一分组对应的所述第二分组的标识。
相当于，接入网设备可以发送第一分组方式和第二分组方式之间的映射关系，从而终端设备能够获得该映射关系，以确定该终端设备所对应的寻呼方式。例如接入网设备可以通过广播消息发送该映射关系，从而使得多个终端设备能够获得该映射关系，且能够节省信令开销。该广播消息例如为系统消息，或者也可以是其他广播消息。
在一种可选的实施方式中，所述广播消息还包括所述第二分组对应的所述第一寻呼方式的信息。
例如，所述的映射关系包括第一分组与第二分组之间的映射关系(或者说子映射关系)，那么所述的广播消息可以包括第一分组的标识，以及包括第一分组对应的第二分组的标识，则接收该广播消息的终端设备就可以确定第一分组与第二分组之间的映射关系。可选的，如果映射关系包括寻呼方式的信息，则该广播消息还可以包括第二分组对应的寻呼方式(例如第一寻呼方式)的信息，例如第一寻呼方式为通过与第二分组对应的RNTI加扰的寻呼方式，则该广播消息可以指示该RNTI。而如果第二分组方式下的各个分组所对应的寻呼方式的信息是通过协议规定，则该广播消息可以不必包括第二分组对应的寻呼方式的信息。如果所述的映射关系还包括其他的子映射关系，则接入网设备发送各个子映射关系的方式都是类似的。
第二方面，提供第二种通信方法，该方法包括：根据指示第一终端设备属于第一分组的第一信息确定所述第一终端设备对应所述第一分组对应的所述第二分组；按照所述第二分组对应的第一寻呼方式监听第一寻呼控制信息。
该方法可由第二通信装置执行，第二通信装置可以是通信设备或能够支持通信设备实现该方法所需的功能的通信装置，例如芯片。示例性地，所述第二通信装置为终端设备，或者为设置在终端设备中的用于实现终端设备的功能的芯片，或者为用于实现终端设备的功能的其他部件。在下文的介绍过程中，以第二通信装置是第一终端设备为例。
第一终端设备能够确定第一终端设备所属的第二分组，从而能够确定该分组所对应的寻呼方式，例如为第一寻呼方式，例如第一寻呼方式对应第一寻呼控制信息。则第一终端设备可以监听第一寻呼控制信息，如果监听到第一寻呼控制信息，则表明第一终端设备被寻呼，第一终端设备可以继续监听寻呼消息等；而如果监听到的寻呼控制信息不是第一寻呼控制信息，那么该终端设备就可以不必继续监听寻呼消息等，通过这种方式可以节省终端设备的功耗，减小虚警的概率。
在一种可选的实施方式中，所述第一信息为所述第一分组的信息，根据第一分组信息确定所述第一终端设备对应的与所述第一分组对应的所述第二分组，包括：
根据所述第一分组与所述第二分组的映射关系确定所述第二分组。

在一种可选的实施方式中，
所述第二分组为默认分组；或，
确定所述第一分组对应于所述第二分组，包括：根据第二参数确定所述第一终端设备属于所述第二分组。
在一种可选的实施方式中，按照所述第二分组对应的第一寻呼方式监听第一寻呼控制信息，包括：
监听所述第二分组对应的第一WUS序列；或，
监听包括第一RNTI的第一DCI，所述第一RNTI对应于所述第二分组；或，

在一种可选的实施方式中，所述方法还包括：
根据所述第一寻呼控制信息监听寻呼消息。
如果监听到第一寻呼控制信息，则表明第一终端设备被寻呼，第一终端设备可以继续监听寻呼消息等，以能够接收第一终端设备的寻呼消息，从而能够根据寻呼消息进行相应操作，例如进入RRC连接态以发送或接收数据等。

具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1)终端设备，包括向用户提供语音和/或数据连通性的设备，具体的，包括向用户提供语音的设备，或包括向用户提供数据连通性的设备，或包括向用户提供语音和数据连通性的设备。例如可以包括具有无线连接功能的手持式设备、或连接到无线调制解调器的处理设备。该终端设备可以经无线接入网(radio access network，RAN)与核心网进行通信，与RAN交换语音或数据，或与RAN交互语音和数据。该终端设备可以包括用户设备(user equipment，UE)、无线终端设备、移动终端设备、设备到设备通信(device-to-device，D2D)终端设备、车到一切(vehicle to everything，V2X)终端设备、机器到机器/机器类通信(machine-to-machine/machine-type communications，M2M/MTC)终端设备、物联网(internet of things，IoT)终端设备、签约单元(subscriber unit)、签约站(subscriber station)，移动站(mobile station)、远程站(remote station)、接入点(access point，AP)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)、或用户装备(user device)等。例如，可以包括移动电话(或称为“蜂窝”电话)，具有移动终端设备的计算机，便携式、袖珍式、手持式、计算机内置的移动装置等。例如，个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、等设备。还包括受限设备，例如功耗较低的设备，或存储能力有限的设备，或计算能力有限的设备等。例如包括条码、射频识别(radio frequency identification，RFID)、传感器、全球定位系统(global positioning system，GPS)、激光扫描器等信息传感设备。

而如上介绍的各种终端设备，如果位于车辆上(例如放置在车辆内或安装在车辆内)，都可以认为是车载终端设备，车载终端设备例如也称为车载单元(on-board unit，OBU)。
本申请实施例中，终端设备还可以包括中继(relay)。或者理解为，能够与基站进行数据通信的都可以看作终端设备。
本申请实施例中，用于实现终端设备的功能的装置可以是终端设备，也可以是能够支持终端设备实现该功能的装置，例如芯片系统，该装置可以被安装在终端设备中。本申请实施例中，芯片系统可以由芯片构成，也可以包括芯片和其他分立器件。本申请实施例提 供的技术方案中，以用于实现终端的功能的装置是终端设备为例，描述本申请实施例提供的技术方案。
2)网络设备，例如包括接入网(access network，AN)设备，例如基站(例如，接入点)，可以是指接入网中在空口通过一个或多个小区与无线终端设备通信的设备，或者例如，一种车到一切(vehicle-to-everything，V2X)技术中的网络设备为路侧单元(road side unit，RSU)。基站可用于将收到的空中帧与IP分组进行相互转换，作为终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP网络。RSU可以是支持V2X应用的固定基础设施实体，可以与支持V2X应用的其他实体交换消息。网络设备还可协调对空口的属性管理。例如，网络设备可以包括LTE系统或高级长期演进(long term evolution-advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，或者也可以包括第五代移动通信技术(the 5th generation，5G)NR系统(也简称为NR系统)中的下一代节点B(next generation node B，gNB)或者也可以包括云接入网(cloud radio access network，Cloud RAN)系统中的集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，本申请实施例并不限定。

3)无线资源控制(radio resource control，RRC)状态，终端设备有3种RRC状态：RRC连接(connected)态、RRC空闲(idle)态和RRC非激活(inactive)态。
RRC连接(connected)态(或，也可以简称为连接态。在本文中，“连接态”和“RRC连接态”，是同一概念，两种称呼可以互换)：终端设备与网络建立了RRC连接，可以进行数据传输。
RRC空闲(idle)态(或，也可以简称为空闲态。在本文中，“空闲态”和“RRC空闲态”，是同一概念，两种称呼可以互换)：终端设备没有与网络建立RRC连接，基站没有存储该终端设备的上下文。如果终端设备需要从RRC空闲态进入RRC连接态，则需要发起RRC连接建立过程。
RRC非激活态(或，也可以简称为非激活态。在本文中，“去活动态”、“去激活态”、“非激活态”、“RRC非激活态”或“RRC去激活态”等，是同一概念，这几种称呼可以互换)：终端设备之前在锚点基站进入了RRC连接态，然后锚点基站释放了该RRC连接，但是锚点基站保存了该终端设备的上下文。如果该终端设备需要从RRC非激活态再次进入RRC连接态，则需要在当前驻留的基站发起RRC连接恢复过程(或者称为RRC连接重建立过程)。因为终端设备可能处于移动状态，因此终端设备当前驻留的基站与终端设备的锚点基站可能是同一基站，也可能是不同的基站。RRC恢复过程相对于RRC建立过程来说，时延更短，信令开销更小。但是基站需要保存终端设备的上下文，会占用基站的存储开销。
4)非连续接收(discontinuous reception，DRX)，简单来说，在DRX机制下，终端设 备可以周期性地进入睡眠状态，不需要监听物理下行控制信道(physical downlink control channel，PDCCH)。
5)本申请实施例中的术语“系统”和“网络”可被互换使用。“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“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的情况，其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a,b,或c中的至少一项(个)，可以表示：a,b,c,a-b,a-c,b-c,或a-b-c，其中a,b,c可以是单个，也可以是多个。
以及，除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的大小、内容、顺序、时序、优先级或者重要程度等。例如，第一寻呼消息和第二寻呼消息，只是为了区分不同的寻呼消息，而并不是表示这两个寻呼消息的大小、内容、发送顺序、优先级或者重要程度等的不同。
前文介绍了本申请实施例所涉及到的一些名词概念，下面介绍本申请实施例涉及的技术特征。
移动通信已经深刻地改变了人们的生活，但人们对更高性能的移动通信的追求从未停止。为了应对未来爆炸性的移动数据流量增长、海量的设备连接、不断涌现的各类新业务和应用场景，第五代移动通信(5G)系统将应运而生。物联网(internet of things，IoT)作为5G的组成部分，其市场需求也增长迅猛。
目前第三代合作伙伴计划(3rd generation partnership project，3GPP)标准已经基于蜂窝网络，针对物联网的特点提出了解决方案，例如窄带物联网(narrow band–internet of things，NB-IoT)和增强机器类型通信(enhance machine type communication，eMTC)网络，利用窄带技术的特点，来承载物联网业务。其中，NB-IoT网络应用了独立于现有蜂窝网络(例如长期演进(long term evolution，LTE)网络)的新空口技术，终端设备的成本更低，支持的速率和移动性更低。eMTC网络作为现有的蜂窝网络(例如LTE网络)的一个子特性，可以在LTE网络中针对物联网的特点，提供IoT业务的支持。与传统蜂窝网络相比，物联网的业务和终端设备具有以下特点：
(1)业务低速率、长周期：与传统蜂窝网络相比，物联网业务产生的数据包更小，同时对于时延通常不是很敏感。
(2)海量连接要求：对大规模部署的智能水/电表，智能家居，汽车，可穿戴设备等物联网终端设备，一个NB-IoT基站下可能存在大量这类型的终端设备(超过数万个)。
(3)低成本要求：较现有蜂窝网络终端，NB-IoT要求终端设备的成本更低，以实现终端设备的海量部署。而低成本的需求要求终端设备的实现复杂性要很低。
(4)低功耗要求：NB-IoT要求终端设备的功耗更低，从而节约终端设备的电池电量，保证终端设备超长的待机时间，进而节约更换电池的人力成本。
(5)业务到达率较低，通常几小时甚至一天以上才会有一次业务，而且相当一部分为上行触发，即网络设备不会寻呼终端设备，只有终端设备有上行业务时，网络设备才会发送下行应答数据。
终端设备在处于RRC空闲态或RRC非激活态时，若核心网设备需要向终端设备发送下行数据，则核心网设备会先向终端设备发送寻呼消息，以寻呼终端设备。终端设备收到 寻呼消息后，会发起RRC连接建立过程从而接收下行数据。
其中，处于RRC空闲态或RRC非激活态的终端设备只在自己的寻呼时机(paging occasion，PO)“醒来”接收寻呼消息。其中，终端设备在自己的PO，首先接收用于指示寻呼消息的PDCCH，或者说，是接收PDCCH承载的下行控制信息(downlink control information，DCI)。该DCI用于指示发送寻呼消息的时频资源等。在接收该DCI之后，终端设备根据该DCI的指示接收寻呼消息。若寻呼消息携带了该终端设备的ID，则表示该终端设备被寻呼，该终端设备需要发起RRC连接建立过程接入基站，以接收下行数据。或者，若寻呼消息中未携带该终端设备的ID，则表示该终端设备未被寻呼，该终端设备可以继续“休眠”，等到下一个PO再“醒来”。
NB-IoT网络和eMTC网络在演进过程中，为了不断优化系统性能，在每个版本中都有新特性加入标准。例如在版本(Rel)-15中，为了减少终端设备监听用于调度寻呼消息的PDCCH的功耗，在每个PO之前引入了WUS。只有终端设备在PO前检测到了WUS，才需要按照传统的方式在相应的PO监听PDCCH，进而监听寻呼消息。
在NB-IoT系统中，寻呼通常由核心网设备发起，核心网设备例如为MME或AMF等。例如，核心网设备会给基站发送包含被寻呼的终端设备的ID等信息的寻呼消息，然后由基站在相应的小区中进行寻呼。终端设备如果收到寻呼消息，会通过基站向核心网设备发送寻呼响应(paging response)。为了防止不能一次寻呼成功，核心网设备在每次发送寻呼消息时通常会维护一个定时器，在该定时器超时时，如果未收到来自终端设备的寻呼响应，则核心网设备会重新发送寻呼消息，直到收到终端设备的寻呼响应为止，对于该过程可参考图1。其中，图1中的T3413即表示所述的定时器。可以看到，在前几次寻呼过程中，核心网设备在定时器T3413超时时均未收到来自终端设备的寻呼响应，因此核心网设备会在定时器T3413超时时重新发送信号线消息。直到在某次发送寻呼消息后，在定时器T3413超时之前核心网设备接收了来自终端设备的寻呼响应，则核心网设备可以停止发送寻呼消息。
真正在空口使用无线通信技术寻呼终端设备的网元是基站，也就是说，核心网设备将寻呼消息发给基站，由基站在空口对终端设备进行寻呼。例如，寻呼过程可参考图2，其中，图2所示的流程以核心网设备是MME为例。
S21、终端设备在任何一次进入RRC连接态与基站通信时，都可以向基站发送该终端设备是否支持WUS特性的信息，基站可接收来自终端设备的该终端设备是否支持WUS特性的信息。
因为WUS特性并不是所有终端设备都能支持的，可能有些终端设备并不支持对于WUS的检测，因此终端设备可以将该终端设备是否支持WUS特性的信息发送给网络，以便网络能够对该终端设备采用对应的寻呼方式。
例如该信息可以承载在UE-无线寻呼信息(RadioPagingInfo)。基站接收该信息后，可以将该信息发送给核心网设备，以便核心网设备下次寻呼时在寻呼消息中一起发送给基站。
S22、基站广播WUS的配置信息，终端设备接收来自基站的配置信息。
WUS的配置信息例如包括WUS的时域位置或WUS的持续时间等。终端设备后续可以根据WUS的配置信息接收WUS。
其中，步骤1和2为准备工作。
S23、MME发送寻呼消息。其中，MME是将寻呼消息发送给基站，基站接收来自MME 的寻呼消息。
该寻呼消息可包含被寻呼的终端设备的ID等信息，以及还可以包含该终端设备是否支持WUS特性的信息。
S24、基站寻呼终端设备。
基站可根据终端设备对于WUS的支持能力来寻呼终端设备。如果被寻呼的终端设备不支持WUS，那么基站可使用传统的寻呼方式，即，直接在PO发送用于调度寻呼消息的PDCCH，如果PDCCH调度了寻呼消息，则之后再发送寻呼消息，如果PDCCH未调度寻呼消息，则之后不发送寻呼消息，而基站不发送WUS。如果被寻呼的终端设备支持WUS，则基站可以在PO之前先发送WUS以唤醒终端设备，之后再发送PDCCH，因为发送了WUS，表明该PDCCH调度了寻呼消息，则之后基站再发送寻呼消息。图2以基站发WUS为例。
考虑进一步降低功耗，在DRX的机制上引入了扩展的DRX(extended DRX，eDRX)，将DRX的周期扩展为更大的值，即终端设备可以“休眠”更长的时间再“醒来”一次。在eDRX中引入了寻呼传输窗(paging transmission window，PTW)，一个eDRX周期内包括一个PTW，该PTW包括一个或多个PO。在一个eDRX周期中，终端设备会在PTW中的一个或多个PO“醒来”接收寻呼消息，直到成功接收到包含该终端设备的ID的寻呼消息或者该PTW结束为止。
对于一个终端设备来说，在一个PTW内，PO和WUS的关系可参考图3。一个WUS可以对应一个或多个PO。WUS在PO前发送，根据协议规定的WUS的持续时间(例如图3所示的最大WUS持续时间(maximum WUS duration))以及PO之前的间隔(Gap)的时长，终端设备在确定PO后，可以相应确定WUS的时域位置。图3中的T DRX表示一个DRX周期的时长。终端设备在确定的时域位置监听WUS，如果WUS指示终端设备在之后的PO会被寻呼，则终端设备可监听后面的PO，而如果WUS指示终端设备在之后的PO不会被寻呼，则终端设备无需按照传统的方式在PO监听PDCCH。由于WUS为一个简单的序列，对于未被寻呼的终端设备来说，只需监听WUS，无需监听PDCCH并进行相应的解码操作，所以监听WUS的功耗小于监听PDCCH的功耗。因此，WUS的引入有利于节省终端设备为接收寻呼消息而在PO监听PDCCH的功耗。
PO是PF中的一个特殊子帧，终端设备确定PF后通过查表就可以确定PO。目前终端设备是通过终端设备的ID以及相应的配置来确定PF。例如，终端设备在一个DRX周期中所检测的PO所在的PF的系统帧号(system frame number，SFN)，以及该SFN对应的PF内的PO的索引等，可以通过下面的公式确定：
PF的SFN满足：

在该SFN中的PO的索引i s满足：

在如上公式中，SFN表示寻呼帧的系统帧号，T表示DRX周期，N表示一个DRX周期内包括的PF的总数量，N s表示一个PF中包含的PO数，mod表示取模运算，UE_ID表示根据终端设备的ID得到的量，floor(x)表示对x向下取整。其中，T、N、N s等均是基站配置的，而UE_ID则是根据终端设备的ID确定的。例如，UE_ID可以是终端设备的5G短临时移动用户 标识(5G-short-temporary mobile subscriber identity，5G-S-TMSI)的后10位。
终端设备可以根据i s和N s进行查表，以确定PO。例如对于FDD，NB-IoT系统的PO可通过查询如下的表1确定：
表1
N s PO(i s＝0) PO(i s＝1) PO(i s＝2) PO(i s＝3)
1 9 N/A N/A N/A
2 4 9 N/A N/A
4 0 4 5 9
例如，N s＝1，i s＝0，则可以确定PO在是一个PF内的序列号为9。
可见PF与终端设备的ID有关，由于取模运算，终端设备的ID和PF的对应关系可能是多对一的，即，同一个PF可能对应很多个终端设备的ID。进而一个PO也会对应多个终端设备的ID。
由于很多终端设备会对应同一个PO，那么就会存在寻呼虚警的问题。例如，一个小区中有100个终端设备确定的PO是同一个PO，则这100个终端设备都会监听该PO或监听该PO对应的WUS。如果基站要寻呼这100个终端设备中的其中一个或几个终端设备，都需要在该PO前发送相应的WUS。在这种情况下，其他未被寻呼的终端设备也会监听到WUS，并因此被唤醒进而监听PDCCH和寻呼消息，这就是所谓的寻呼虚警。对于未被寻呼的终端设备来说，在WUS之后监听PDCCH以及寻呼消息等，是没有意义的，只会带来额外的功率损耗。
鉴于此，提供本申请实施例的技术方案。在本申请实施例中，将终端设备进行了分组，对不同分组的终端设备可采用不同的寻呼方式。对于一个终端设备来说，如果通过监听确定寻呼方式不是该终端设备所在的分组的寻呼方式，那么该终端设备就可以不必监听寻呼消息等，通过这种方式可以节省终端设备的功耗，减小虚警的概率。
本申请实施例提供的技术方案可以应用于第四代移动通信技术(the 4th generation，4G)系统中，例如LTE系统，或可以应用于5G系统中，例如NR系统，或者还可以应用于下一代移动通信系统或其他类似的通信系统，只要存在一个实体可以对另一个实体发起寻呼即可，具体的不做限制。另外，本申请实施例在介绍过程中是以网络设备和终端设备之间的空口通信过程为例，实际上本申请实施例提供的技术方案也可以应用于侧行链路(sidelink，SL)，只要一个终端设备能够对另一个终端设备发起寻呼即可。例如，本申请实施例提供的技术方案可以应用于设备到设备(device-to-device，D2D)场景，可以是NR D2D场景也可以是LTE D2D场景等，或者可以应用于车到一切(vehicle to everything，V2X)场景，可以是NR V2X场景也可以是LTE V2X场景等，例如可应用于车联网，例如V2X、LTE-V、车与车(vehicle-to-vehicle，V2V)等，或可用于智能驾驶，智能网联车等领域。
请参见图4，为本申请实施例的一种应用场景。在图4中，接入网设备通过无线传输方式服务于终端设备。核心网设备可以对终端设备发起寻呼。
图4中的核心网设备例如为MME或AMF等。图4中的接入网设备例如为基站。其中，基站在不同的系统对应不同的设备，例如在4G系统中可以对应4G中的基站，例如eNB，在5G系统中对应5G中的基站，例如gNB。当然本申请实施例所提供的技术方案也可以应用于未来的移动通信系统中，因此图4中的接入网设备也可以对应未来的移动通信系统中的接入网设备。图4以接入网设备是基站为例，实际上参考前文的介绍，接入网设 备还可以是RSU等设备。另外，图4中的终端设备以手机为例，实际上根据前文对于终端设备的介绍可知，本申请实施例的终端设备不限于手机。
下面结合附图介绍本申请实施例提供的方法。
本申请实施例提供一种通信方法，请参见图5，为该方法的流程图。在下文的介绍过程中，以该方法应用于图4所示的网络架构为例。
为了便于介绍，在下文中，以该方法由网络设备和终端设备执行为例。因为本实施例是以应用在图4所示的网络架构为例，因此，下文中所述的核心网设备可以是图4所示的网络架构中的核心网设备，下文中所述的接入网设备可以是图4所示的网络架构中的接入网设备，下文中所述的终端设备可以是图4所示的网络架构中的终端设备。
S501、第一终端设备向核心网设备发送第二信息，核心网设备接收来自终端设备的第二信息。第二信息可以用于确定第一终端设备在第一分组方式下所属的分组。第一分组方式是按照第一参数进行分组的方式，或者第一分组方式也可以称为归类方式等。可以理解为，核心网设备对多个终端设备进行大概的归类，这样核心网设备在寻呼终端设备时，只需在寻呼信息里携带该终端设备所属的分组的信息即可。例如，核心网设备可以对于每个终端设备单独寻呼，则在寻呼消息中可以包括该终端设备在第一分组方式下所属的分组的信息，当然还可以包括该终端设备的标识等信息。又例如，核心网设备对于一组终端设备可一并寻呼，即，通过发送一条寻呼消息来寻呼一组终端设备，则只需在该寻呼信息里包括该分组的信息即可，无需在该寻呼信息里携带每个终端设备分别对应的信息，有助于减小信令开销。
第二信息例如包括第一取值，或包括第一分组的信息，或者也可以包括其他信息。
第一取值是第一终端设备对应于第一参数的取值。第一取值可以用于确定第一终端设备在第一分组方式下所属的分组，对此可以理解为，网络设备(例如核心网设备)获得第一取值后，可以根据第一取值确定第一终端设备在第一分组方式下所属的分组。
作为第一参数的一种可选的实施方式，第一参数例如为寻呼概率参数，寻呼概率参数可以指示第一终端设备被寻呼的概率。那么第一取值可以是寻呼概率参数的取值。
例如，第一取值可以是具体的概率值，例如第一取值为85％，表明第一终端设备被寻呼的概率为85％，这种具体的概率值可以是第一终端设备根据历史信息所确定的。例如第一终端设备可以统计在第一时长内接收寻呼消息的情况，并确定具体的概率。
又例如，第一取值也可以是寻呼概率范围，例如第一取值可以指示第一终端设备被寻呼的概率为高概率，或中概率，或低概率。如果第一取值为寻呼概率范围，那么第一终端设备也可以根据历史信息来确定。例如第一终端设备可以统计在第一时长内接收寻呼消息的情况，但第一终端设备无需确定具体的概率，只需大概确定第一终端设备接收寻呼的概率是高还是低即可。或者，第一终端设备在这种情况下也可以先确定具体的概率值，同时第一终端设备也事先获知了寻呼概率范围与概率值之间的对应关系，例如高概率对应的概率值的范围为[70％，100％]，中概率对应的概率值的范围为[40％，70％)，低概率对应的概率值的范围为[0，40％)。那么第一终端设备在确定第一终端设备被寻呼的概率值后，可以确定该概率值对应于哪个寻呼概率范围，第一取值就可以指示该寻呼概率范围。其中，寻呼概率范围与概率值之间的对应关系，可以预配置在第一终端设备中，例如在第一终端设备出厂或维修时预配置，或者也可以通过协议规定，或者也可以由网络设备(例如核心网设备)配置并发送给第一终端设备。
作为第一参数的另一种可选的实施方式，第一参数也可以是业务参数，该业务参数例如指示第一终端设备执行上行业务或下行业务，或者理解为，该业务参数指示第一终端设备是上行业务触发类型或下行业务触发类型。如果该业务参数指示第一终端设备执行上行业务，或者指示第一终端设备是上行业务触发类型，可以理解为，第一终端设备仅执行上行业务，或者，第一终端设备执行上行业务的概率大于执行下行业务的概率。如果该业务参数指示第一终端设备执行下行业务，或者指示第一终端设备是下行业务触发类型，可以理解为，第一终端设备仅执行下行业务，或者，第一终端设备执行下行业务的概率大于执行上行业务的概率。例如，第一终端设备仅执行上行业务，或者执行上行业务的概率大于执行下行业务的概率，则第一终端设备可以确定该业务参数指示第一终端设备执行上行业务(或确定该业务参数指示第一终端设备为上行业务触发类型)；或者，第一终端设备仅执行下行业务，或者执行下行业务的概率大于执行上行业务的概率，则第一终端设备可以确定该业务参数指示第一终端设备执行下行业务(或确定该业务参数指示第一终端设备为下行业务触发类型)。第一终端设备要确定业务参数，可以根据第一终端设备在单位时间内的通信次数确定，例如第一终端设备在单位时间内的通信次数小于预设阈值，则可以确定第一终端设备为上行业务触发类型，相反的，如果第一终端设备在单位时间内的通信次数大于或者等于预设阈值，则可以确定第一终端设备为下行业务触发类型。
示例性的，在根据第一终端设备的业务参数确定第一终端设备所属的分组时，该业务参数实际上也可以指示第一终端设备会被寻呼的概率，具有不同的业务特征的终端设备被寻呼的概率不同，这样就可以根据业务特征，将被寻呼的概率较高的终端设备和被寻呼的概率较低的终端设备划分至不同的分组中。因此，虽然终端设备的业务参数没有明确地体现终端设备会被寻呼的概率，但是该业务参数可以间接体现出终端设备会被寻呼的概率。通常情况下，如果业务参数指示一个终端设备为上行业务触发类型，则可以理解为该终端设备被寻呼的概率较低，而如果业务参数指示该终端设备为下行业务触发类型，则可以理解为该终端设备被寻呼的概率较高。
例如第一终端设备为水表或电表等，则此类终端设备一般只需向网络设备(例如接入网设备)发送读数等信息，网络设备一般不会向此类终端设备发送下行信息。那么对于此类终端设备来说，可以确定业务参数用于指示第一终端设备执行上行业务，或者指示第一终端设备是上行业务触发类型。又例如，第一终端设备为路灯，则一般是网络设备(例如接入网设备)会向此类终端设备发送开关信令，以控制该终端设备的开启或关闭，终端设备一般不会向网络设备发送上行信息。那么对于此类终端设备来说，可以确定业务参数用于指示第一终端设备执行下行业务，或者指示第一终端设备是下行业务触发类型。
当然第一参数也可以是其他参数，例如也可以是终端设备的ID等，则第一取值就是第一终端设备的ID。对于第一参数是何种参数不做限制。
或者，第二信息也可以包括第一分组的信息。终端设备向核心网设备发送第二信息，就是为了使得核心网设备确定该终端设备在第一分组方式下所属的分组。那么有一种情况是，核心网设备事先将第一分组方式下的划分标准告知第一终端设备，则第一终端设备获得第一终端设备对应于第一参数的第一取值后，可以自行根据第一分组方式下的划分标准确定第一终端设备所属的分组，即，第一终端设备可以确定第一分组的信息，第一分组的信息可以指示第一终端设备属于第一分组，第一分组就是第一分组方式下的分组。其中，第一分组方式可以是按照第一参数的取值将终端设备进行分组的方式。第一终端设备将第 一分组的信息发送给核心网设备，核心网设备就可以确定第一终端设备属于第一分组，无需再对第一终端设备进行分组操作，可以减少核心网设备的工作量。需要注意的是，所述的第一分组，可以是指第一分组方式下的任意一个分组，而不是指第一分组方式下按照某种顺序(例如按照概率值的大小顺序)排列的第一个分组。后续将要涉及的“第二分组”等也是类似的含义。
例如第一参数为寻呼概率参数，第一终端设备确定第一终端设备对应于第一参数的第一取值为65％。核心网设备事先告知第一终端设备，概率值的范围为[80％，100％]对应分组1，概率值的范围为[60％，80％)对应分组2，概率值的范围为[40％，60％)对应分组3，概率值的范围为[20％，40％)对应分组4，概率值的范围为[0，20％)对应分组5。那么第一终端设备可以确定第一终端设备属于分组1，第一终端设备可以将分组1的信息发送给核心网设备。从而核心网设备可确定第一终端设备属于分组1。
例如，第一终端设备可以通过非接入层(non-access stratum，NAS)消息将第一信息发送给核心网设备。
S502、核心网设备确定第一终端设备在第一分组方式下所属的分组。例如核心网设备确定第一终端设备在第一分组方式下属于第一分组，则S502也可以理解为，核心网设备确定第一终端设备的第一分组的信息，第一分组的信息可指示第一终端设备属于第一分组。
如果核心网设备接收的是来自第一终端设备的第一取值，则核心网设备可以根据第一取值将第一终端设备划分到相应的分组。第一分组方式可以是按照第一参数将终端设备进行分组的方式，核心网设备可以事先确定第一分组方式下的F个分组的划分标准，或者，第一分组方式下的F个分组的划分标准也可以通过协议规定，F为大于或等于1的整数。例如，第一参数为寻呼概率参数，F＝5，F个分组的划分标准为，概率值的范围为[80％，100％]对应分组1，概率值的范围为[60％，80％)对应分组2，概率值的范围为[40％，60％)对应分组3，概率值的范围为[20％，40％)对应分组4，概率值的范围为[0，20％)对应分组5。又例如，第一参数为寻呼概率参数，F＝3，M个分组的划分标准为，高概率对应分组1，中概率对应分组2，低概率对应分组3。例如，在S501之前，核心网设备可以事先告知终第一端设备具体向核心网设备发送何种类型(例如概率值或寻呼概率范围等)的第一取值，从而终端设备所发送的第一取值可以用于核心网设备将第一终端设备划分到F个分组中的一个分组。
例如F个分组的划分标准为，概率值的范围为[80％，100％]对应分组1，概率值的范围为[60％，80％)对应分组2，概率值的范围为[40％，60％)对应分组3，概率值的范围为[20％，40％)对应分组4，概率值的范围为[0，20％)对应分组5。则核心网设备可以事先告知第一终端设备需要向核心网设备发送概率值。例如第一终端设备发送的第一取值为85％，则核心网设备可以将第一终端设备划分到分组1。
又例如，F个分组的划分标准为，高概率对应分组1，中概率对应分组2，低概率对应分组3。则核心网设备可以事先告知第一终端设备需要向核心网设备发送寻呼概率范围。例如第一终端设备发送的第一取值为低概率，则核心网设备可以将第一终端设备划分到分组3。
或者，如果核心网设备接收的是来自第一终端设备的第一分组的信息，则核心网设备可以确定第一终端设备属于第一分组，无需再划分。
或者，由于核心网设备会存储第一终端设备的注册信息，第一终端设备的注册信息中 可以包括第一终端设备的业务特征，例如根据第一终端设备的注册信息可以确定第一终端设备被寻呼的概率(概率值或寻呼概率范围)，因此，核心网设备也可以根据第一终端设备的注册信息确定第一终端设备在第一分组方式下所属的分组。或者，核心网设备可能存储了第一终端设备的统计信息，第一终端设备的统计信息例如可指示第一终端设备被寻呼的概率，或者指示第一终端设备的业务特征等，因此，核心网设备也可以根据第一终端设备的统计信息确定第一终端设备在第一分组方式下所属的分组。如果是如上两种情况中的任意一种，则第一终端设备无需向核心网设备发送第二信息，即，无需执行S501，可以减少信令开销。
S503、核心网设备向第一终端设备发送第一分组的信息，第一终端设备接收来自接入网设备的第一分组的信息。
核心网设备确定第一终端设备属于第一分组，则可以将第一分组的信息发送给第一终端设备，从而使得终端设备能够明确第一终端设备在第一分组方式下属于第一分组。例如，核心网设备可以通过NAS消息将第一分组的信息发送给第一终端设备。其中，如果终端设备发送的第二信息是第一分组的信息，则核心网设备可以再次向第一终端设备发送第一分组的信息，或者核心网设备也可以不必向第一终端设备发送第一分组的信息。
需要说明的是，S501～S503可以视为第一终端设备和核心网设备协商第一终端设备在第一分组方式下所属的分组的过程。该协商过程对于接入网设备而言可以是透明的，即接入网设备无需获知该协商过程。多个终端设备都可以通过如上的协商过程确定各自所属的分组。在图5中，以所述的终端设备是第一终端设备为例。另外，S501～S503均为可选的步骤，不是必须执行的，在图5中用虚线表示。
S504、接入网设备根据第一参数确定第一分组方式下的M个分组，以及，根据第二参数确定第二分组方式下的N个分组。M和N均为大于或等于1的整数。
其中，S504可以发生在S501～S503之前，或者S504可以发生在S501～S503之后，或者S504和S501～S503中的某个步骤也可以同时发生。
例如第二分组方式是根据第二参数进行分组的方式，第一分组方式是根据第一参数进行分组的方式。第一参数例如为寻呼概率参数、业务参数或终端设备的ID等，第二参数例如为寻呼概率参数，或者为业务参数，或者为终端设备的ID等。
虽然第一分组方式是核心网设备采用的分组方式，且终端设备与核心网设备协商分组的过程对于接入网设备来说是透明的，但第一分组方式可以通过协议规定，或者核心网设备也可以告知接入网设备等，即，接入网设备可以获知第一分组方式。例如M＝F，接入网设备划分的M个分组与核心网设备划分的F个分组相同。也就是说，接入网设备与核心网设备所采用的分组方式相同，可以使得接入网设备所确定的映射关系能够与核心网设备的分组方式相符，从而使得接入网设备尽量能够根据该映射关系确定各个终端设备对应的寻呼方式。或者，接入网设备划分的M个分组也可能并不完全等同于F个分组，例如F个分组中包括的部分分组并不包括在M个分组中，或者F个分组与M个分组完全不同，都有可能出现。
第一参数与第二参数可以是同一种参数，例如均为寻呼概率参数；或者，第一参数与第二参数也可以是不同的参数，例如第一参数为寻呼概率参数，第二参数为业务参数，或者第一参数为寻呼概率参数，第二参数为终端设备的ID。如果第一参数与第二参数是同一种参数，则第一参数的取值和第二参数的取值可以是同种类型的取值；例如均为概率值； 或者，第一参数的取值和第二参数的取值也可以是不同类型的取值，例如第一参数的取值为概率值，第二参数的取值为寻呼概率范围。
例如，第二参数为寻呼概率参数，N＝4，接入网设备所划分的4个分组为，概率值的范围为[75％，100％]对应分组1，概率值的范围为[50％，75％)对应分组2，概率值的范围为[25％，50％)对应分组3，概率值的范围为[0，25％)对应分组4。
又例如，第二参数为寻呼概率参数，N＝2，接入网设备所划分的2个分组为，高概率对应分组1，低概率对应分组2。
再例如，第二参数为终端设备的ID，接入网设备可以按照终端设备的ID的可能取值划分N个分组。
对于按照第一参数进行分组的方式也是类似的，不多赘述。
S505、接入网设备建立M个分组和N个分组之间的映射关系。
接入网设备根据第一参数划分了M个分组，且根据第二参数划分了N个分组，那么接入网设备可以建立M个分组和N个分组之间的映射关系，可以理解为，接入网设备将M个分组映射到N个分组，使得M个分组中的每个分组可以对应N个分组中的一个或多个分组，或者，使得N个分组中的每个分组可以对应M个分组中的一个或多个分组。可以理解为，M个分组和N个分组之间的映射关系包括P个子映射关系，P个子映射关系中的每个子映射关系为M个分组中的一个分组与N个分组中的一个分组之间的映射关系，P为大于或等于1的整数。
另外，接入网设备可以为P个子映射关系中的每个子映射关系分别关联一种寻呼方式，其中，一个子映射关系对应一种寻呼方式，一种寻呼方式可对应一个或多个子映射关系。例如，P个子映射关系中的子映射关系1对应寻呼方式1，P个子映射关系中的子映射关系2对应寻呼方式2。或者，对此也可以理解为，接入网设备是为第二分组方式下的每个分组分别关联一种寻呼方式，其中，第二分组方式下的一个分组对应一种寻呼方式，一种寻呼方式可对应第二分组方式下的一个或多个分组。在本申请实施例中，不同的寻呼方式可以对应不同的寻呼控制信息，或者理解为，接入网设备发送的寻呼控制信息不同，就是使用了不同的寻呼方式。例如，寻呼方式1对应寻呼控制信息1，寻呼方式2对应寻呼控制信息2，等等。寻呼控制信息例如为WUS(或者称为WUS序列)，或者例如为用于调度寻呼消息的PDCCH(或者说是DCI)。
如果寻呼控制信息为WUS序列，那么寻呼控制信息不同，可以是指WUS序列不同(这里可以理解为构成WUS序列的码字不同)，或者也可以是指WUS序列的资源位置不同，WUS序列的资源位置，例如包括如下的一种或多种：WUS序列的时域资源位置，WUS序列的频域资源位置，或，WUS序列的码域资源位置。例如有两个WUS序列，如果这两个WUS序列的时域资源位置不同，则认为这两个WUS序列的资源位置不同；或者，如果这两个WUS序列的频域资源位置不同，则认为这两个WUS序列的资源位置不同；或者，如果这两个WUS序列的码域资源位置不同，则认为这两个WUS序列的资源位置不同；或者，如果这两个WUS序列的频域资源位置不同，且时域资源位置不同，则认为这两个WUS序列的资源位置不同；或者，如果这两个WUS序列的频域资源位置不同，且码域资源位置不同，则认为这两个WUS序列的资源位置不同；或者，如果这两个WUS序列的时域资源位置不同，且码域资源位置不同，则认为这两个WUS序列的资源位置不同；或者，如果这两个WUS序列的时域资源位置不同，频域资源位置不同，且码域资源位置不同，则 认为这两个WUS序列的资源位置不同。
例如，寻呼控制信息不同是指WUS序列不同，则例如寻呼控制方式1对应WUS序列1，寻呼控制方式2对应WUS序列2，WUS序列1和WUS序列2是不同的序列。又例如，寻呼控制信息不同是指WUS序列的资源位置不同，则例如寻呼控制方式1对应WUS序列1，寻呼控制方式2也对应WUS序列1，但寻呼控制方式1对应的WUS序列1的时域资源位置为时域资源1，寻呼控制方式2对应的WUS序列1的时域资源位置为时域资源2，则寻呼控制方式1和寻呼控制方式2对应的WUS序列的资源位置是不同的。对于一个终端设备来说，接入网设备可以将所述的映射关系通知给终端设备。因此，一个终端设备检测WUS序列后，根据对该WUS序列的检测结果，以及所述的映射关系，就可以确定该终端设备在当前的PO是否被寻呼。
或者，如果寻呼控制信息为DCI，那么寻呼控制信息不同，可以是指DCI所包括的子映射关系的信息不同，或者是指用于加扰DCI的无线网络临时标识(radio network tempory identity，RNTI)不同。
作为DCI不同的第一种实施方式，DCI不同是指DCI所包括的子映射关系的信息不同，或者说，是指DCI所包括的分组的信息不同，这里的分组，指的是第二分组方式下的分组。DCI所包括的分组的信息可以包括比特地图(bitmap)，或者也可以包括分组的标识(例如分组的ID)，或者也可以包括bitmap和分组的标识。例如分组的信息包括bitmap，则DCI可以包括第一bitmap，第一bitmap可包括一个或多个比特，其中的每个比特对应第二分组方式下的一个分组或多个分组。如果第一bitmap中的一个比特的取值为第一值，则表明该比特所对应的一个或多个分组被寻呼，或者说，是表明该比特所对应的一个或多个分组所包括的终端设备被寻呼；而如果第一bitmap中的一个比特的取值为第二值，则表明该比特所对应的一个或多个分组未被寻呼，或者说，是表明该比特所对应的一个或多个分组所包括对应的终端设备未被寻呼。第一值例如为“1”，第二值例如为“0”；或者，第一值为“0”，第二值为“1”。通过bitmap就可以指示多个分组，指示方式较为明确。
在本申请实施例中，第一bitmap可以通过DCI包括的预留(reserved)比特来承载；或者，第一bitmap可以通过DCI包括的用于承载其他信息的比特承载；或者也可以在DCI中增加新的域(field)，第一bitmap通过新增的域承载。
例如，第一bitmap通过DCI包括的用于承载其他信息的比特承载。这里所述的其他信息，例如短消息(short message)，或者也可以是除短消息外的其他信息，这里以短消息为例。
在DCI中包括短消息，用于承载短消息的字段一共为8比特，这8比特的状态对应的含义可参考表2。
表2
Figure PCTCN2021093578-appb-000003
Figure PCTCN2021093578-appb-000004
从表2可以看到，这8比特中的第1个比特和2个比特已有对应的含义，而第3个比特至第8个比特当前均为预留比特，没有特定含义。那么本申请实施例可以将第3个比特至第8个比特中的一个或多个比特加以利用，作为第一bitmap。例如利用这6个比特承载第一bitmap，则第一bitmap包括6个比特，这6个比特的每个比特可以指示第二分组方式下的一个或多个分组。例如第一值为“1”，第二值为“0”，N＝8，这6个比特按照从高位到低位的顺序，第一个比特指示分组1和分组2，第二个比特指示分组3，第三个比特指示分组4，第四个比特指示分组5、分组6和分组7，第五个比特指示分组7，第六个比特指示分组8。那么，如果这6个比特的取值为“101000”，则代表对应于分组1、分组2或分组4的终端设备被寻呼，而对应于分组3、分组5、分组6、分组7或分组8的终端设备均未被寻呼。
对于一个终端设备来说，接入网设备可以将所述的映射关系通知给终端设备，例如接入网设备可以广播所述的映射关系。因此，一个终端设备接收DCI后，例如该DCI所包括的这6个比特的取值为“101000”，且该终端设备在第二分组方式下对应于分组1、分组2或分组4，则该终端设备可以确定被寻呼，该终端设备可以继续在当前的PO监听寻呼消息；而如果该终端设备在第二分组方式下对应于分组3、分组5、分组6、分组7或分组8，则该终端设备确定未被寻呼，该终端设备无需在当前的PO监听寻呼消息，而是可以到下个PO到来时再监听DCI。
或者，DCI所包括的分组的信息也可以包括分组的标识。在本申请实施例中，分组的标识可以通过DCI包括的预留比特来承载；或者，分组的标识可以通过DCI包括的用于承载其他信息的比特承载；或者也可以在DCI中增加新的域，分组的标识通过新增的域承载。
例如，分组的标识通过DCI包括的用于承载其他信息的比特承载。这里所述的其他信息，例如短消息，或者也可以是除短消息外的其他信息。以分组的标识通过DCI包括的用于承载短消息的比特承载为例，则也可以利用如上所介绍的用于承载短消息的8个比特中的第3个比特至第8个比特中的一个或多个比特来承载分组的标识。例如，一个分组的标识占用K个比特，则可固定占用这6个比特中的K个比特来承载分组的标识，K为大于或等于1且小于或等于6的整数。以K＝4为例，例如可固定占用这8个比特中的第3个比特至第6个比特来承载分组的标识，这4个比特的取值不同，则对应不同分组的标识。又例如，K＝6，则，这4个比特的取值不同，就对应不同分组的标识。
对于一个终端设备来说，接入网设备可以将所述的映射关系通知给终端设备，例如接 入网设备可以广播所述的映射关系。因此，一个终端设备接收DCI后，根据该DCI所包括的这6个比特中的用于指示分组的标识的比特的取值，以及该终端设备在第二分组方式下所属的分组，就可以确定该终端设备在当前的PO是否被寻呼。
作为DCI不同的第二种实施方式，DCI不同是指用于加扰DCI的RNTI不同。例如寻呼控制方式1对应RNTI 1，寻呼控制方式2对应RNTI 2，RNTI 1和RNTI 2是不同的RNTI。
对于一个终端设备来说，接入网设备可以将所述的映射关系通知给终端设备，例如接入网设备可以广播所述的映射关系。因此，一个终端设备在检测DCI时，如果根据该终端设备在第二分组方式下所属的分组所对应的RNTI检测DCI成功，则该终端设备确定该终端设备在当前的PO被寻呼，而如果根据该终端设备在第二分组方式下所属的分组对应的RNTI检测DCI失败，则该终端设备确定该终端设备在当前的PO未被寻呼。
其中，M个分组可以与N个分组完全相同，即，M＝N，且M个分组就是N个分组。例如，第一参数为寻呼概率参数，第二参数也是寻呼概率参数，且M个分组对应的划分标准为寻呼概率范围，N个分组对应的划分标准也是寻呼概率范围，M＝N＝3，M个分组包括高概率对应的分组1，中概率对应的分组2，以及低概率对应的分组3，N个分组也包括高概率对应的分组1，中概率对应的分组2，以及低概率对应的分组3。在这种情况下，可以认为接入网设备建立M个分组和N个分组之间的映射关系，或者也可以认为接入网设备无需建立M个分组和N个分组之间的映射关系，相当于接入网设备根据第一分组方式对应的分组就能确定对应的寻呼方式。
或者，M个分组与N个分组不同。例如M不等于N，或者M个分组的划分标准与N个分组的划分标准不同等，都可以认为M个分组与N个分组不同。
例如，第一参数为寻呼概率参数，第二参数也为寻呼概率参数，但M个分组对应的划分标准为寻呼概率范围，N个分组对应的划分标准是概率值。例如，M个分组包括高概率对应的分组0，中概率对应的分组1，以及低概率对应的分组2；N个分组包括，概率值的范围为[80％，100％]对应分组a，概率值的范围为[60％，80％)对应分组b，概率值的范围为[40％，60％)对应分组c，概率值的范围为[20％，40％)对应分组d，概率值的范围为[0，20％)对应分组e。例如接入网设备将分组0映射为对应分组a和分组b，将分组1映射为对应分组c和分组d，将分组2映射为对应分组e。可参考表3，为映射关系的示例：

例如表3中，分组1-分组a是一个子映射关系，对应寻呼方式1，或者说，分组a对应寻呼方式1；分组1-分组b是又一个子映射关系，对应寻呼方式2，或者说，分组b对应寻呼方式1，以此类推。例如，对于一个终端设备来说，如果该终端设备在第一分组方式下属于分组0(即，该终端设备的ID mod 4＝0)，同时在第二分组方式下属于分组a，则该终端设备需要按照寻呼方式1监听寻呼控制信息。或者，如果该终端设备在第一分组方式下属于分组0，同时在第二分组方式下属于分组b，则该终端设备需要按照寻呼方式2 监听寻呼控制信息。
又例如，第一参数为寻呼概率参数，第二参数也为寻呼概率参数，但M个分组对应的划分标准为概率值，N个分组对应的划分标准是寻呼概率范围。例如，N个分组包括高概率对应的分组0，以及低概率对应的分组1；M个分组包括，概率值的范围为[80％，100％]对应分组a，概率值的范围为[60％，80％)对应分组b，概率值的范围为[40％，60％)对应分组c，概率值的范围为[20％，40％)对应分组d，概率值的范围为[0，20％)对应分组e。例如接入网设备将分组a、分组b和分组c映射为对应分组0，将分组d和分组e映射为对应分组1。可参考表4，为映射关系的示例：
表4

例如表4中，分组a-分组0是一个子映射关系，对应寻呼方式1，或者说，分组0对应寻呼方式1；分组b-分组0是又一个子映射关系，也对应寻呼方式1，或者说，分组0对应寻呼方式1，以此类推。例如，对于一个终端设备来说，如果该终端设备在第一分组方式下属于分组a，同时在第二分组方式下属于分组0(即，该终端设备的ID mod 4＝0)，则该终端设备需要按照寻呼方式1监听寻呼控制信息。
再例如，第一参数为业务参数，第二参数为终端设备的ID。例如，M个分组包括上行业务触发类型对应的分组a，以及下行业务触发类型对应的分组b；N个分组包括，终端设备的ID的范围为范围1对应分组0，终端设备的ID的范围为范围1对应分组1，终端设备的ID的范围为范围1对应分组2，以及终端设备的ID的范围为范围1对应分组3。由于终端设备的ID不能直接反应终端设备的业务特征，因此接入网设备在设置映射关系时，可以建立分组a与分组0之间的子映射关系、分组a与分组1之间的子映射关系、分组a与分组2之间的子映射关系、分组a与分组3之间的子映射关系，以及，可以建立分组b与分组0之间的子映射关系、分组b与分组1之间的子映射关系、分组b与分组2之间的子映射关系、分组b与分组3之间的子映射关系。可参考表5，为映射关系的示例：
表5
Figure PCTCN2021093578-appb-000007
例如表5中，虽然分组0会分别对应分组a和分组b，但对应于分组a的分组0和对应于分组b的分组0也可以视为不同的分组，因此表5所示的第二分组方式下可以认为有8个分组。分组a-分组0是一个子映射关系，对应寻呼方式1，或者说，分组0在对应于分组a时，对应寻呼方式1；分组b-分组0是又一个子映射关系，对应寻呼方式5，或者说，分组0在对应于分组b时，对应寻呼方式5，以此类推。例如，对于一个终端设备来说，如果该终端设备在第一分组方式下属于分组a，同时在第二分组方式下属于分组0(即，该终端设备的ID mod 4＝0)，则该终端设备需要按照寻呼方式1监听寻呼控制信息。或者，如果一个终端设备在第一分组方式下属于分组b，同时在第二分组方式下属于分组2(即，该终端设备的ID mod 4＝2)，则该终端设备需要按照寻呼方式7监听寻呼控制信息。
如上所述的几种映射关系，只是映射关系的示例。本申请实施例不限制接入网设备所设置的M个分组与N个分组之间的映射关系。另外，在如上的映射关系中，都是以映射关系包括了对应的寻呼方式的信息为例。在实际应用中，第二分组方式下的各个分组分别对应的寻呼方式也可以通过协议规定，或者也可以预配置在终端设备中，如果是这样的情况，则所述的映射关系只需包括第一分组方式与第二分组方式之间的映射关系即可，不必包括第二分组方式下的各个分组分别对应的寻呼方式的信息。
在本申请实施例中，接入网设备可以不必局限于核心网设备的分组，而是可以自行设置新的分组，只需建立两种分组方式的映射关系即可，对于接入网设备的限制较小。而且，如果核心网设备的分组粒度较细，例如核心网设备是按照寻呼概率参数对应的概率值来分组，核心网设备按照5％为粒度来划分，则核心网设备可以划分20组。如果接入网设备未自行设置新的分组，则需要为这20组分别配置寻呼方式，接入网设备可能并不支持这么多种寻呼方式。在本申请实施例中，接入网设备可以再按照第二分组方式来分组，例如接入网设备也按照寻呼概率参数对应的概率值来分组，但接入网设备按照25％为粒度来划分，则核心网设备可以划分4组，且接入网设备可以建立两种分组方式的映射关系。从而接入网设备只需支持较少的寻呼方式即可完成寻呼，较为灵活，且对于核心网设备所划分的每个分组包括的终端设备，接入网设备都能确定对应的寻呼方式。
或者，所述的映射关系也可以不由接入网设备设置，例如可以通过协议规定，或者可以预配置在接入网设备中，那么接入网设备可不必执行S504和S505。可见，S504和S505是可选的步骤，不是必须执行的，在图5中用虚线表示。
S506、接入网设备发送所述的映射关系。
例如接入网设备可通过广播消息发送所述的映射关系，则多个终端设备都可以接收所述的映射关系。广播消息例如为系统消息，或者也可以是其他消息。或者接入网设备也可以通过单播消息向终端设备发送所述的映射关系，例如接入网设备只向有节能需求的终端设备发送所述的映射关系等。单播消息例如为高层消息，例如RRC消息或媒体接入控制(media access control，MAC)控制元素(control element，CE)，或者也可以是物理层消息，例如DCI等。图5以第一终端设备接收映射关系为例。
例如，所述的映射关系包括第一分组与第二分组之间的映射关系(或者说子映射关系)，那么所述的广播消息可以包括第一分组的标识，以及包括第一分组对应的第二分组的标识，则接收该广播消息的终端设备就可以确定第一分组与第二分组之间的映射关系。可选的，如果映射关系包括寻呼方式的信息，则该广播消息还可以包括第二分组对应的寻呼方式(例如第一寻呼方式)的信息，例如第一寻呼方式为通过与第二分组对应的RNTI加扰的 寻呼方式，则该广播消息可以指示该RNTI。而如果第二分组方式下的各个分组所对应的寻呼方式的信息是通过协议规定，则该广播消息可以不必包括第二分组对应的寻呼方式的信息。如果所述的映射关系还包括其他的子映射关系，则接入网设备发送各个子映射关系的方式都是类似的。
当然，如果所述的映射关系通过协议规定，则接入网设备可以不必发送该映射关系，即，不必执行S506。因此，S506是可选的步骤，不是必须执行的，在图5中用虚线表示。
S507、第一终端设备根据第一信息确定第一终端设备属于第二分组，或者说，确定第一终端设备对应的寻呼方式。
第一信息可以是第一分组的信息，或者说第一信息用于指示第一终端设备属于第一分组；或者，第一信息不包括任何分组的信息。其中，如果第一信息是第一分组的信息，则第一终端设备是在S503中接收的来自核心网设备的第一分组的信息，或者第一终端设备是自行确定的第一分组的信息。而如果第一信息不包括任何分组的信息，这表明第一终端设备在第一分组方式下不属于任何分组，例如核心网设备并未向第一终端设备发送第一分组的信息，第一终端设备也未自行确定第一分组的信息。如果是这种情况，实际上也可以认为第一信息并不存在，即，可以认为，如果第一终端设备侧未获得第一分组的信息，这也可以视为一种隐式存在的第一信息，这就表明第一终端设备在第一分组方式下不对应任何分组。
如果第一信息是第一分组的信息，第一终端设备接收了来自核心网设备的第一分组的信息，也接收了所述的映射关系，则第一终端设备可以确定第一终端设备在第二分组方式下对应于哪个分组。例如，第一终端设备确定在该映射关系中，第一分组对应于第二分组(或者说，第一终端设备根据第一分组与第二分组的映射关系，确定第二分组)，则第一终端设备确定第一终端设备对应于第二分组，或者说，第一终端设备确定第一终端设备对应于第二分组所对应的寻呼方式。或者，第一终端设备确定在该映射关系中，第一分组不对应第二分组方式下的任何分组，例如在第一分组方式中并不存在第一分组，则该映射关系中就不会包括与第一分组对应的分组。如果是这种情况，则第一终端设备也可以确定第一终端设备对应于第二分组，或者说，第一终端设备确定第一终端设备对应于第二分组所对应的寻呼方式。例如第二分组为第一默认分组，所谓的第一默认分组可以理解为，对于无法对应到该映射关系的终端设备，都认为属于第一默认分组，第一默认分组可以对应默认寻呼方式，或者称为缺省(default)寻呼方式。或者，第一终端设备可以根据第二参数确定第一终端设备所属的分组，即，虽然在该映射关系中不存在与第一分组对应的任何分组，第一终端设备还是可以确定第一终端设备在第二分组方式下所属的分组，例如第一终端设备根据第二参数确定第一终端设备属于第二分组，从而第一终端设备可以按照第二分组对应的寻呼方式监听寻呼控制信息。
相当于，在实际应用中，由于核心网设备与终端设备协商分组的过程对接入网设备来说是透明的，因此可能核心网设备的F个分组与接入网设备的M个分组并不是完全对应的。例如核心网设备按照寻呼概率参数对应的寻呼概率范围分组，接入网设备也按照寻呼概率参数对应的寻呼概率范围分组，而核心网设备分为三组，分别为高概率、中概率和低概率，但接入网设备只分为两组，分别为高概率和低概率。那么，如果第一分组的信息指示第一终端设备属于中概率，则第一终端设备确定在该映射关系中，第一分组不对应第二分组方式下的任何分组。或者，可能核心网设备的分组方式与接入网设备的分组方式(第一分组 方式)不同，例如核心网设备按照寻呼概率参数分组，而接入网设备采用的第一分组方式为按照业务参数分组。如果是这种情况，第一终端设备也会确定在该映射关系中，第一分组不对应第二分组方式下的任何分组。为此，本申请实施例设置了一种回退机制，使得即使核心网设备的分组方式与接入网设备的分组方式不能完全对应，也能对终端设备进行寻呼。以此可以扩大寻呼范围，提高寻呼成功率。
而如果第一信息不包括任何分组的信息，即，不存在第一终端设备所属的分组的信息，在这种情况下，也可以认为第一终端设备在第一分组方式下属于第一分组，这种情况下的第一分组不同于前述的第一分组，此时的第一分组实际上是不存在的分组，即，在第一分组方式下不属于任何分组的终端设备，都可以认为属于第一分组，第一分组也可以视为是一种默认分组，例如称为第二默认分组，第一分组并不是第一分组方式下的分组。如果是这种情况，则第一终端设备也可以确定第一终端设备对应于第二分组，或者说，第一终端设备确定第一终端设备对应于第二分组所对应的寻呼方式。或者，如果第一信息不包括任何分组的信息，即，不存在第一终端设备所属的分组的信息，在这种情况下，可以不必经过确定第一终端设备属于第一分组的过程，而是，如果第一信息不包括任何分组的信息，即，不存在第一终端设备所属的分组的信息，则可以确定第一终端设备对应第二分组。例如第二分组为第一默认分组，或者，第一终端设备可以根据第二参数确定第一终端设备所属的分组，例如第一终端设备根据第二参数确定第一终端设备属于第二分组。关于这部分内容，可参考上一段落的描述。
这实际上也相当于一种回退方式，即，如果在映射关系中无法确定一个终端设备对应的寻呼方式，也可以为该终端设备重新确定另一种寻呼方式，从而能够寻呼该终端设备。以此可以扩大寻呼范围，提高寻呼成功率。
另外，如果第一参数和第二参数是不同的参数，例如第一参数是寻呼概率参数或业务参数，第二参数是终端设备的ID等，那么第一终端设备根据第一信息确定第一终端设备在第二分组方式下对应于第二分组，具体可以是，第一终端设备根据第一信息、第一终端设备对应于第二参数的取值、以及第一分组方式与第二分组方式之间的映射关系，确定第一终端设备在第二分组方式下对应于第二分组。例如可参考前文的表5，第一终端设备在第一分组方式下属于分组a，第一终端设备根据第一终端设备的ID确定在第二分组方式下属于分组0，则第一终端设备可以确定在第二分组方式下对应于分组a-分组0中的分组0，从而确定对应寻呼方式1。
S508、核心网设备获得第一终端设备的寻呼信息。
寻呼信息例如包括第一终端设备的标识，例如第一终端设备的ID等信息。当然寻呼信息还可以包括寻呼相关的信息。
S508是可选的步骤，在图5中用虚线表示。
S509、核心网设备根据第一终端设备的标识，确定第一终端设备在第一分组方式下属于第一分组。或者，核心网设备也可以不确定第一终端设备在第一分组方式下所属的分组，如果是这种情况，则可不必执行S509，因此S509是可选的步骤，在图5中用虚线表示。或者，核心网设备也可能确定第一终端设备在第一分组方式下不属于任何分组(或者说，确定第一终端设备不属于任何分组)。其中，S509以核心网设备确定第一终端设备在第一分组方式下属于第一分组，或确定第一终端设备在第一分组方式下不属于任何分组为例。
由于核心网设备已经确定了M个分组分别包括的终端设备，因此核心网设备在获知第 一终端设备的标识后，就可以确定该标识所属的分组。例如核心网设备确定第一终端设备属于M个分组中的第一分组，则核心网设备可以确定第一分组的信息。
S510、核心网设备向接入网设备发送第一寻呼消息，接入网设备接收来自核心网设备的第一寻呼消息。第一寻呼消息可包括第一终端设备的标识。
可选的，第一寻呼消息还可以指示第一终端设备所属的第一分组。其中，第一寻呼消息指示第一分组的信息可以包括不同的情况。例如一种情况为，第一消息寻呼包括第一分组的信息，在这种情况下，第一分组是第一分组方式下的一个分组。例如，核心网设备在S509中确定了第一终端设备在第一分组方式下属于第一分组，则核心网设备可以将第一分组的信息包括在第一寻呼消息中。又例如，另一种情况为，第一寻呼消息不包括第一终端设备所属的分组的信息，在这种情况下，第一分组视为默认分组(例如前文所述的第二默认分组)，即，在第一分组方式下不属于任何分组的终端设备，都可以认为属于第一分组。例如，核心网设备在S509中未确定第一终端设备在第一分组方式下所属的分组，或者核心网设备确定第一终端设备在第一分组方式下不属于任何分组，则第一寻呼消息中不包括第一终端设备所属的分组的信息。
或者，如果第一寻呼消息不包括第一终端设备所属的分组的信息，这种情况也可以认为第一寻呼消息不指示第一终端设备所属的分组，或者说，第一寻呼消息不包括第一终端设备所属的分组的信息。
S511、接入网设备确定第二分组。或者说，确定第一终端设备属于第二分组。
例如，第一寻呼消息包括第一分组的信息，且第一分组方式与第二分组方式之间的映射关系中包括第一分组的信息，则接入网设备可以确定该映射关系中第一分组对应的第二分组，即，确定第一终端设备在第二分组方式下对应第二分组。
又例如，第一寻呼消息包括第一分组的信息，且第一分组方式与第二分组方式之间的映射关系中不包括第一分组的信息，则接入网设备可以确定第一分组对应的第二分组。例如第二分组为第一默认分组，所谓的第一默认分组可以理解为，对于无法对应到该映射关系的终端设备，都认为属于第一默认分组，第一默认分组可以对应默认寻呼方式，或者称为缺省寻呼方式。或者，接入网设备可以根据第二参数确定第一终端设备所属的分组，即，虽然在该映射关系中不存在与第一分组对应的任何分组，接入网设备还是可以确定第一终端设备在第二分组方式下所属的分组，例如接入网设备根据第二参数确定第一终端设备属于第二分组，从而接入网设备可以按照第二分组对应的寻呼方式监听寻呼控制信息。
再例如，第一寻呼消息不包括第一终端设备在第一分组方式下所属的分组的信息，也可以认为第一终端设备在第一分组方式下属于第一分组。如果是这种情况，则接入网设备也可以确定第一终端设备对应于第二分组。或者，第一寻呼消息不包括第一终端设备在第一分组方式下所属的分组的信息，则接入网设备可以确定第一终端设备对应于第二分组，而不必确定第一终端设备对应第一分组，即，接入网设备无需经历确定第一终端设备属于第一分组的步骤，就可以确定第一终端设备对应第二分组。例如第二分组为第一默认分组，或者，接入网设备可以根据第二参数确定第一终端设备所属的分组，例如接入网设备根据第二参数确定第一终端设备属于第二分组。关于这部分内容，可参考上一段落的描述。
当然，如果第一寻呼消息包括第一分组的信息，且第一分组方式与第二分组方式之间的映射关系中不包括第一分组的信息，或者第一寻呼消息不包括第一终端设备在第一分组方式下所属的分组的信息，那么接入网设备确定第一终端设备所属的分组的方式，与第一 终端设备确定第一终端设备所属的分组的方式，应该是一致的，例如二者都确定第一终端设备所属的第二分组是第一默认分组，或者都按照第二参数确定第一终端设备所属的分组，从而保证二者确定结果的一致性，提高寻呼成功率。
S512、接入网设备按照第二分组对应的第一寻呼方式寻呼第一终端设备，而第一终端设备也按照第二分组对应的第一寻呼方式监听第一寻呼控制信息。
第一寻呼方式例如对应第一寻呼控制信息，那么按照第二分组对应的第一寻呼方式寻呼第一终端设备，可以实现为，接入网设备发送第一寻呼控制信息，以寻呼第一终端设备，相应的，第一终端设备可监听来自接入网设备的第一寻呼控制信息，图5的S512即以此为例。当然，实际上如果接入网设备发送第一寻呼控制信息，寻呼的应该是第一寻呼控制信息在第二分组方式下所对应的分组对应的全部终端设备，第一寻呼控制信息例如在第二分组方式下对应一个或多个分组，第二分组可以是其中的一个。图5只以第一终端设备监听第一寻呼控制信息为例。
如果寻呼控制信息为WUS序列，那么例如第一寻呼控制信息为第二分组对应的第一WUS序列，则接入网设备可以发送第一WUS序列。第一终端设备监听第一WUS序列，如果确定监听到的WUS序列是第一WUS序列，则表明第一终端设备被寻呼，第一终端设备可以继续在当前的PO监听寻呼消息。而如果确定监听到的WUS序列不是第一WUS序列，则表明第一终端设备未被寻呼，第一终端设备在当前的PO可无需监听寻呼消息，以节省功耗。
或者，如果寻呼控制信息为DCI，寻呼控制信息不同是指DCI包括的分组的信息不同，且分组的信息通过第一bitmap实现。那么例如，第一寻呼控制信息为第一DCI，第一DCI包括第一bitmap，第一bitmap中对应于第二分组的比特的取值为第一值，接入网设备可以发送所述的第一DCI。第一终端设备监听DCI，如果确定监听到的DCI包括的bitmap中对应于第二分组的比特的取值为第一值，则表明第一终端设备被寻呼，第一终端设备可以继续在当前的PO监听寻呼消息。而如果确定监听到的DCI包括的bitmap中对应于第二分组的比特的取值不是第一值，则表明第一终端设备未被寻呼，第一终端设备在当前的PO可无需监听寻呼消息，以节省功耗。
或者，如果寻呼控制信息为DCI，寻呼控制信息不同是指DCI包括的分组的信息不同，且子映射关系的信息为分组的标识。那么例如，第一寻呼控制信息为第一DCI，第一DCI包括第二分组的标识，接入网设备可以发送所述的第一DCI。第一终端设备监听DCI，如果确定监听到的DCI包括第二分组的标识，则表明第一终端设备被寻呼，第一终端设备可以继续在当前的PO监听寻呼消息。而如果确定监听到的DCI不包括第二分组的标识，例如DCI包括其他分组的标识，或者不包括任何分组的标识，则表明第一终端设备未被寻呼，第一终端设备在当前的PO可无需监听寻呼消息，以节省功耗。
或者，如果寻呼控制信息为DCI，寻呼控制信息不同是指用于加扰DCI的RNTI不同。那么例如，第一寻呼控制信息为第一DCI，第一DCI是通过第二分组对应的第一RNTI加扰，接入网设备可以发送所述的第一DCI。第一终端设备监听DCI，如果确定监听到的DCI包括是通过第一RNTI加扰，则表明第一终端设备被寻呼，第一终端设备可以继续在当前的PO监听寻呼消息。而如果确定监听到的DCI不是通过第一RNTI加扰，则表明第一终端设备未被寻呼，第一终端设备在当前的PO可无需监听寻呼消息，以节省功耗。
S513、第一终端设备监听寻呼消息。
如果第一终端设备确定第一终端设备被寻呼，则第一终端设备可以在当前的PO继续监听寻呼消息。而如果第一终端设备确定第一终端设备未被寻呼，则第一终端设备在当前的PO无需监听寻呼消息，即无需执行S513，而是在下个PO到来时，第一终端设备可继续监听寻呼控制信息，以此类推。因此，S513为可选的步骤，在图5中用虚线表示。
在本申请实施例中，将终端设备进行了分组，对不同分组的终端设备可采用不同的寻呼方式。对于一个终端设备来说，如果通过监听确定该寻呼方式不是该终端设备所在的分组的寻呼方式，那么该终端设备就可以不必监听寻呼消息等，通过这种方式可以节省终端设备的功耗，减小虚警的概率。
而且不同的寻呼方式对应不同的终端设备组，而不同的终端设备组对应的寻呼概率不同，例如寻呼概率较高的终端设备属于一个分组，寻呼概率较低的终端设备属于另一个分组，这两个分组对应的寻呼方式不同。那么寻呼概率较高的终端设备被寻呼的次数较多，但由于此类终端设备对应的寻呼方式与寻呼概率较低的终端设备对应的寻呼方式不同，因此寻呼概率较低的终端设备会认为自身并未被寻呼，因此不必监听寻呼消息。通过这种方式减少了寻呼概率较低的终端设备被打扰的概率，有助于减小此类终端设备的功耗。
下面结合附图介绍本申请实施例中用来实现上述方法的装置。因此，上文中的内容均可以用于后续实施例中，重复的内容不再赘述。

本申请实施例还提供一种通信装置，该通信装置可以是终端设备也可以是电路。该通信装置可以用于执行上述方法实施例中由第一终端设备所执行的动作。
当该通信装置为第一终端设备时，图8示出了一种简化的终端设备的结构示意图。便于理解和图示方便，图8中，终端设备以手机作为例子。如图8所示，终端设备包括处理器、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，以及对终端设备进行控制，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，有些种类的终端设备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设备时，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8中仅示出了一个存储器和处理器。在实际的终端设备产品中，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设备的收发单元(收发单元可以是一个功能单元，该功能单元能够实现发送功能和接收功能；或者，收发单元也可以包括两个功能单元，分别为能够实现接收功能的接收单元和能够实现发送功能的发送单元)，将具有处理功能的处理器视为终端设备的处理单元。如图8所示，终端设备包括收发单元810和处理单元820。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810中用于实现接收功能的器件视为接收单元，将收发单元810中用于实现发送功能的器件视为发送单元，即收发单元810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。
