通信系统中，终端在一个非连续接收(Discontinuous Reception，DRX)的接收周期内，可以只在相应的寻呼无线帧上的寻呼时刻(Paging Occasion，PO)监听物理下行控制信道(Physical downlink control channel，PDCCH)上是否携带有寻呼无线网络临时标识(Paging Radio Network Temporary Identifier，P-RNTI)，然后再去判断相应的物理下行共享信道(Physical downlink shared channel，PDSCH)上是否有承载寻呼消息。
对于新空口(New Radio，NR)，为了支持灵活的网络配置，网络侧可通过系统消息发送寻呼提前指示(Paging Early Indication，PEI)的配置以指示使用PEI，但是终端和网络侧对于PEI或寻呼分组的理解可能不一致，例如终端在当前小区监听PEI，但网络不发送PEI，这样会导致寻呼丢失，影响终端通信。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile  Internet Device，MID)、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(Vehicle User Equipment，VUE)、行人终端(Pedestrian User Equipment，PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(personal computer，PC)、柜员机或者自助机等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以包括接入网设备或核心网设备，其中，接入网设备也可以称为无线接入网设备、无线接入网(Radio Access Network，RAN)、无线接入网功能或无线接入网单元。接入网设备可以包括基站、WLAN接入点或WiFi节点等，基站可被称为节点B、演进节点B(eNB)、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、家用B节点、家用演进型B节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例进行介绍，并不限定基站的具体类型。核心网设备可以包含但不限于如下至少一项：核心网节点、核心网功能、移动管理实体(Mobility Management Entity，MME)、接入移动管理功能(Access and Mobility Management Function，AMF)、会话管理功能(Session Management Function，SMF)、用户平面功能(User Plane Function，UPF)、策略控制功能(Policy Control Function，PCF)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)、边缘应用服务发现功能(Edge Application Server Discovery Function，EASDF)、统一数据管理(Unified Data Management，UDM)，统一数据仓储(Unified Data Repository，UDR)、归属用户服务器(Home Subscriber Server，HSS)、集中式网络配置(Centralized network configuration，CNC)、网络存储功能(Network Repository Function，NRF)，网络开放功能(Network Exposure Function，NEF)、本地NEF(Local NEF，或L-NEF)、绑定支持功能(Binding Support Function，BSF)、应用功能(Application Function，AF)等。需要说明的是，在本申请实施例中仅以NR系统中的核心网设备为例进行介绍，并不限定核心网设备的具体类型。
目前，网络侧设备可以向空闲态、非激活态和连接态的终端发送寻呼，寻呼过程可以由核心网设备触发，用于通知某个终端接收寻呼请求，或者由eNB/gNB触发，用于通知系统信息更新，以及通知终端接收地震和海啸预警 系统(Earthquake and Tsunami Warning System，ETWS)以及商业移动警报服务(Commercial Mobile Alert Service，CMAS)等信息。
终端在一个DRX的接收周期内，可以只在相应的寻呼无线帧(Paging Frame，PF)上的寻呼时刻(Paging Occasion，PO)监听物理下行控制信道(Physical downlink control channel，PDCCH)上是否携带有寻呼无线网络临时标识(Paging Radio Network Temporary Identifier，P-RNTI)，然后再去判断相应的物理下行共享信道(Physical downlink shared channel，PDSCH)上是否有承载寻呼消息。
进一步地，网络侧设备可以将监听同一个PO的终端进行分组，并通过PEI指示所寻呼的终端分组。
在LTE中，寻呼唤醒信号(Paging with Wake Up Signal)就是一种基于寻呼提前指示的寻呼接收，网络侧设备可以仅仅在最后使用的小区来使用寻呼提前指示。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的寻呼指示方法进行详细地说明。
请参照图2，图2是本申请实施例提供的一种寻呼指示方法的流程图，如图2所示，所述方法包括以下步骤：
步骤201、在满足目标条件的情况下，终端在当前小区使用PEI和寻呼分组中的至少一项。
其中，所述目标条件包括如下至少一项：
所述终端在所述当前小区处于非连接态；
所述当前小区不限制所述终端使用所述PEI和寻呼分组中的至少一项；
所述终端在所述当前小区被分配有核心网分组号。
本申请实施例中，当满足目标条件时，终端在当前小区使用PEI和/或寻呼分组。其中，所述当前小区可以是指终端当前驻留的小区。
例如，终端从小区1移动至小区2，则小区2为所述当前小区；若终端在小区2处于非连接态，例如终端在小区2被释放，则终端能够在小区2使用PEI和/或寻呼分组。或者，终端在小区1被释放，然后重选到小区2，然后又回到小区1，则小区1为所述当前小区；或者，若终端在小区1被分配有核心网分组号，则终端能够在小区1使用PEI和/或寻呼分组。可选地，终端的移动及当前小区还可以是其他的可能情况，本实施例不做过多列举。
需要说明地，本申请实施例中所述目标条件可能有多种情况。可选地，目标条件为：当前小区是终端最近被释放或被挂起的小区；或者，目标条件为：终端接收到第一指示，且第一指示用于指示不要求仅在所述终端最后使用的小区使用PEI和寻呼分组中的至少一项，或者终端在当前小区接收到的 系统消息或无线资源控制(Radio Resource Control，RRC)信令中不包括所述第一指示；或者，目标条件为：终端在当前小区被分配有核心网分组号，且所述当前小区包括对应的寻呼分组配置；或者，目标条件为：终端接收到第一指示，第一指示用于指示仅在所述终端最后使用的小区使用PEI和寻呼分组中的至少一项，且当前小区是终端最近被释放或被挂起的小区；或者，目标条件为：终端接收到第一指示，第一指示用于指示仅在所述终端最后使用的小区使用PEI和寻呼分组中的至少一项，且当前小区是终端从连接态进入空闲态或非激活态的小区；或者，目标条件为：终端在当前小区被分配有核心网分组号，且终端接收到第一指示，第一指示用于指示仅在所述终端最后使用的小区使用PEI和寻呼分组中的至少一项。当然，目标条件还可以是其他的可能情况，本实施例不做具体赘述。
本申请实施例中，在满足目标条件的情况下，终端在当前小区使用PEI和寻呼分组中的至少一项，这样也就使得终端能够明确在何种情况下能够使用PEI和/或寻呼分组，也使得网络侧设备可以灵活地配置终端使用PEI和/或寻呼分组，以确保网络侧设备和终端对于PEI和/或寻呼分组的使用有一致的理解，保证寻呼接收成功，确保终端和网络侧设备的通信。
可选地，所述终端在所述当前小区处于非连接态包括如下至少一项：
所述终端在所述当前小区被释放，或者所述终端在所述当前小区被挂起；
所述终端在所述当前小区从连接态进入空闲态或非激活态。
例如，终端在所述当前小区被释放(release)，则终端能够在所述当前小区使用PEI和寻呼分组中的至少一项；或者，终端在所述当前小区被挂起(suspend)，则终端能够在所述当前小区使用PEI和寻呼分组中的至少一项；或者，所述终端在所述当前小区从连接态进入空闲态(IDLE)或非激活态(例如RRC_INACTIVE)的小区，则终端能够在所述当前小区使用PEI和寻呼分组中的至少一项。这样，通过上述几种情况，使得终端能够确定是否能够在当前小区使用PEI和/或寻呼分组，以更好地规范终端的行为。
可选地，所述终端在所述当前小区被释放，或者所述终端在所述当前小区被挂起包括：
所述终端在所述当前小区为最近一次被释放，或者所述终端在所述当前小区为最近一次被挂起。
例如，所述当前小区是终端最近一次被释放的小区，则终端能够在所述当前小区使用PEI和寻呼分组中的至少一项；或者，所述当前小区是终端最近一次被挂起的小区，则终端能够在所述当前小区使用PEI和寻呼分组中的至少一项。
需要说明地，所述最近一次(most recently)可以理解为终端移动至当前 小区之前的最后一次被释放或被挂起。示例性地，假设目标条件为：所述终端在所述当前小区为最近一次被释放，或者所述终端在所述当前小区为最近一次被挂起(或者称：所述当前小区是所述终端最近一次被释放的小区，或者所述当前小区是所述终端最近一次被挂起的小区)；若终端在小区(cell)1被释放或被挂起，然后重选到cell2，且在cell2被释放或被挂起，后来又小区选择或重选回到cell1；此时，当前小区是cell1，终端在cell1满足：当前小区是所述终端被释放或被挂起的小区，但不是最近一次被释放或被挂起的小区，其中cell2是终端最近一次被释放或被挂起的小区。这种情况下，当前小区是不满足“所述当前小区是所述终端最近一次被释放的小区，或者当前小区是所述终端最近一次被挂起的小区”这一条件的，终端不能在cell1使用PEI和寻呼分组中的至少一项。
可选地，所述终端在所述当前小区从连接态进入空闲态或非激活态包括：
所述终端在所述当前小区为最近一次从连接态进入空闲态或非激活态。
也就是说，若当前小区是终端最近一次从连接态进入空闲态或非激活态的小区，则终端能够在所述当前小区使用PEI和寻呼分组中的至少一项。其中，所述最近一次的定义可以具体参考上述描述，此处不再赘述。
本申请实施例中，所述当前小区不限制所述终端使用所述PEI和寻呼分组中的至少一项基于如下任意一项实现：
所述终端接收到第一指示，且所述第一指示用于指示不要求仅在所述终端最后使用的小区使用PEI和寻呼分组中的至少一项；
所述终端在当前小区接收到的系统消息或无线资源控制RRC信令中不包含第一指示，所述第一指示用于指示是否仅在所述终端最后使用的小区使用PEI和寻呼分组中的至少一项。
需要说明地，在所述终端接收到第一指示的情况下，所述第一指示可以是包含在网络侧设备发送的系统消息或RRC信令中。所述第一指示可以表征为用于指示是否要求仅在最后使用的小区使用PEI和寻呼分组中的至少一项，那么，第一指示可以用于指示仅在最后使用的小区使用PEI和寻呼分组中的至少一项，或者，第一指示还可以用于指示不要求仅在最后使用的小区使用PEI和寻呼分组中的至少一项。
例如，若终端接收到第一指示，且该第一指示用于指示仅在终端最后使用的小区使用PEI和寻呼分组中的至少一项，若当前小区被指示是最后使用的小区，则终端在当前小区使用PEI和寻呼分组中的至少一项。或者，终端接收到第一指示，若该第一指示用于指示不要求仅在终端最后使用的小区使用PEI和寻呼分组中的至少一项，也即指示终端可以在任意小区使用PEI和寻呼分组中的至少一项，则终端在当前小区可以使用PEI和寻呼分组中的至 少一项。或者，若终端在当前小区接收到的系统消息或RRC信令中不包含第一指示，也即没有明确是否仅在最后的小区使用PEI和寻呼分组中的至少一项，这种情况下，终端可以在当前小区使用PEI和寻呼分组中的至少一项。
本申请实施例中，网络侧设备可以向终端发送第一指示，进而通过第一指示来灵活配置终端使用PEI和/或寻呼分组，以确保网络侧设备和终端对于PEI和/或寻呼分组的使用有一致的理解，保障寻呼接收成功。
可选地，在所述终端在所述当前小区被分配有核心网分组号的情况下，所述当前小区提供对应的寻呼分组配置，所述寻呼分组配置用于核心网分配或控制分组。
本申请实施例中，若终端在当前小区被分配有核心网分组号(Core Network subgroup Identity document，CN subgroup ID)，且网络侧设备通过系统消息为当前小区提供了寻呼分组配置，则终端可以在当前小区使用PEI和寻呼分组中的至少一项。这样，也就使得终端能够基于网络侧设备为当前小区分配的标识来确定是否能够使用PEI和/或寻呼分组，以确保网络侧设备和终端对于PEI和/或寻呼分组的使用有一致的理解，保障寻呼接收成功。其中，所述寻呼分组配置包含用于核心网分配或控制分组(CN-assigned subgrouping，CN-controlled subgrouping)。
可选地，所述目标条件还可以包括如下至少一项：
所述终端支持PEI和寻呼分组中的至少一项；
所述当前小区支持PEI和寻呼分组中的至少一项。
其中，所述当前小区支持PEI和/或寻呼分组，包括当前小区通过系统消息或非接入服务(non-access-stratum，NAS)信令或RRC专用信令(例如RRC释放消息)指示其支持PEI和/或寻呼分组。所述寻呼分组包括如下至少一项：
基于终端标识的分组(UE-ID based subgrouping)；
核心网分配的分组(CN-assigned subgrouping)。
为更好地理解，所述步骤101还可以表示为：
在满足目标条件的情况下，终端在当前小区使用PEI和寻呼分组中的至少一项；
其中，所述目标条件包括如下至少一项：
1.所述当前小区是所述终端被释放或被挂起的小区；
2.所述当前小区是所述终端最近一次被释放或最近一次被挂起的小区；
3.所述当前小区是所述终端从连接态进入空闲态或非激活态的小区；
4.所述当前小区是所述终端最近一次从连接态进入空闲态或非激活态的小区；
5.所述终端接收到第一指示，所述第一指示用于指示仅在最后使用的小 区使用PEI和寻呼分组中的至少一项，且所述UE被指示所述当前小区是最后使用的小区；
6.所述终端接收到第一指示，所述第一指示用于指示不要求仅在最后使用的小区使用PEI和寻呼分组中的至少一项；
7.所述终端在当前小区接收到的系统消息或RRC信令中不包含第一指示；
8.所述终端在所述当前小区被分配有核心网分组号，且所述当前小区提供对应的寻呼分组配置，所述寻呼分组配置用于核心网分配或控制分组；
9.所述终端接收到第一指示，所述第一指示用于指示仅在最后使用的小区使用PEI和寻呼分组中的至少一项，且所述终端在所述当前小区被释放或被挂起；
10.所述终端接收到第一指示，所述第一指示用于指示仅在最后使用的小区使用PEI和寻呼分组中的至少一项，且所述终端在所述当前小区从连接态进入空闲态或非激活态；
11.所述终端支持PEI和寻呼分组中的至少一项；
12.所述当前小区支持PEI和寻呼分组中的至少一项。
本申请实施例，通过明确目标条件的各种情况，使得终端能够明确在何种情况下能够使用PEI和/或寻呼分组，确保寻呼接收成功。
可选地，所述方法还可以包括：
在所述终端进行小区选择或小区重选后，所述终端基于接收到的第一指示执行第一操作，其中，所述第一操作包括如下至少一项：
在所述第一指示用于指示仅在所述终端最后使用的小区使用PEI和寻呼分组中的至少一项的情况下，在当前小区不使用PEI或寻呼分组；
在所述第一指示用于指示不要求仅在所述终端最后使用的小区使用PEI和寻呼分组中的至少一项的情况下，在当前小区使用PEI和寻呼分组中的至少一项。
例如，终端在进行小区选择或小区重选后，终端可以执行如下至少一项操作：
若终端接收到的第一指示用于指示仅在所述终端最后使用的小区使用PEI和寻呼分组中的至少一项，则所述终端在当前小区不使用PEI和/或寻呼分组；
若终端接收到的第一指示用于指示不要求仅在所述终端最后使用的小区使用PEI和寻呼分组中的至少一项(或者用于指示终端在任意小区使用PEI和寻呼分组中的至少一项)，则所述终端在当前小区可以使用PEI和/或寻呼分组。
其中，所述第一指示可以是网络侧设备发送给终端，例如所述第一指示 包含在网络侧设备发送的系统消息或RRC信令中。本申请实施例中，也就能够通过网络侧设备发送的第一指示，来对进行小区选择或小区重选后的终端在当前小区是否使用PEI和寻呼分组进行配置，进而以更好地规范终端的寻呼接收行为。
可选地，在所述终端为通过小区选择或小区重选驻留所述当前小区的终端的情况下，所述终端执行所述第一操作；
在所述终端为在所述当前小区被释放或被挂起的终端的情况下，所述终端不执行所述第一操作。
也就是说，只有在终端为通过小区选择或小区重选过来的终端，才会执行上述第一操作，对于在当前小区被释放或被挂起的终端，不能执行上述第一操作。
本申请实施例中，所述步骤201可以包括：
在所述终端被当前小区释放或挂起，且所述终端驻留在所述当前小区的情况下，若所述当前小区支持PEI和寻呼分组中的至少一项，所述终端在所述当前小区使用PEI和寻呼分组中的至少一项。
例如，终端在小区1被释放或被挂起后，且终端驻留在该小区1，若该小区1支持PEI和寻呼分组中的至少一项，则所述终端在该小区1使用PEI和寻呼分组中的至少一项。
可选地，所述当前小区为所述最后使用的小区。例如，终端接收到第一指示，所述第一指示用于指示仅在终端最后使用的小区使用PEI和寻呼分组中的至少一项，在所述终端被当前小区释放或挂起，且所述终端驻留在所述当前小区的情况下，若所述当前小区支持PEI和寻呼分组中的至少一项，终端在所述当前小区使用PEI和/或寻呼分组，此时，所述当前小区可以被认为是所述第一指示中所指示的最后使用的小区。
可选地，在所述终端在所述当前小区被释放或被挂起的情况下，若所述终端接收到所述第一指示，所述终端忽略所述第一指示。
例如，终端在小区1(当前小区)被释放或被挂起，若终端接收到第一指示，所述第一指示用于指示仅在终端最后使用的小区使用PEI和寻呼分组中的至少一项，此时终端可以忽略所述第一指示，例如不论小区1是否是终端使用PEI和/或寻呼分组的最后使用的小区，终端都可以在小区1使用PEI和/或寻呼分组，以确保终端寻呼接收成功。
本申请实施例中，所述方法还可以包括：
在所述终端被目标小区释放或挂起，且所述终端从其他小区再移动回所述目标小区的情况下，所述终端执行如下至少一项：
所述终端在所述目标小区使用PEI和寻呼分组中的至少一项；
所述终端在所述目标小区基于所述第一指示确定是否使用PEI和寻呼分组中的至少一项，所述第一指示用于指示是否仅在所述终端最后使用的小区使用PEI和寻呼分组中的至少一项；
所述终端自主决定在所述目标小区是否使用PEI和寻呼分组中的至少一项。
例如，终端在小区1(目标小区)被释放或挂起，然后重选到小区2，然后又回到小区1，在这种情况下，终端可以在小区1使用PEI和/或寻呼分组；或者，终端也可以基于接收到的第一指示确定是否在小区1使用PEI和/或寻呼分组，比如第一指示为仅在终端最后使用的小区使用PEI和寻呼分组中的至少一项，若小区1不是所述最后使用的小区，则终端在小区1不使用PEI和/或寻呼分组；或者，终端也可以是自行决定是否使用PEI和/或寻呼分组。这样，也就使得终端对于是否使用PEI和/或寻呼分组更加灵活。
可选地，在所述终端在所述目标小区使用PEI和寻呼分组中的至少一项的情况下，所述目标小区为所述最后使用的小区。具体地，在所述终端被目标小区释放或挂起，若所述终端从其他小区再移动回所述目标小区，所述终端在目标小区使用PEI和/或寻呼分组，这种情况下，所述目标小区被认为是第一指示中的最后使用的小区。需要说明地，若终端从目标小区移动至其他小区，则终端在其他小区的寻呼接收行为可以是基于所述第一指示来确定。
可选地，在所述终端在所述目标小区使用PEI和寻呼分组中的至少一项的情况下，若所述终端在所述当前小区被释放或被挂起，且所述终端接收到所述第一指示，所述终端忽略所述第一指示。
例如，所述终端在小区1(目标小区)使用PEI和寻呼分组中的至少一项，若终端从小区1移动至小区2，若终端在小区2被释放或挂起，且终端接收到第一指示，所述第一指示为仅在终端最后使用的小区使用PEI和寻呼分组中的至少一项，此时终端可以忽略所述第一指示，也即终端可以在小区2使用PEI和/或寻呼分组，以确保终端寻呼接收成功。
本申请实施例中，所述终端在当前小区使用PEI和寻呼分组中的至少一项之前，所述方法还包括：
所述终端接收系统消息或第一RRC消息，所述系统消息或第一RRC消息包括如下至少一项：
用于指示所述终端是否被允许在当前小区使用PEI和寻呼分组中的至少一项；
用于指示所述当前小区是否是最后使用的小区；
第一指示，所述第一指示用于指示是否仅在所述终端最后使用的小区使用PEI和寻呼分组中的至少一项。
需要说明地，所述系统消息或第一RRC消息为网络侧设备发送给终端，终端能够基于所述系统消息或第一RRC消息确定是否在当前小区使用PEI和/或寻呼分组。例如，若所述系统消息或第一RRC消息指示终端允许在当前小区使用PEI和/或寻呼分组，则所述终端在当前小区使用PEI和/或寻呼分组；或者，系统消息或第一RRC消息指示所述当前小区为最后使用小区，则终端可以是在当前小区使用PEI和/或寻呼分组；或者，所述系统消息或第一RRC消息还可以是包括第一指示，则终端基于所述第一指示确定是否在当前小区使用PEI和/或寻呼分组；或者，所述系统消息或第一RRC消息包括第一指示，以及还用于指示当前小区为最后使用的小区，则终端可以是基于第一指示在当前小区使用PEI和/或寻呼分组；等，本实施例不做具体赘述。
这样，网络侧设备能够通过系统消息或第一RRC消息来对终端是否在当前小区使用PEI和/或寻呼分组进行灵活配置，以确保网络侧设备和终端对于PEI和/或寻呼分组的使用具有一致的理解，保障寻呼接收成功。
可选地，所述方法还可以包括：
所述终端发送用于请求PEI和寻呼分组中的至少一项的第二RRC消息；
其中，所述第二RRC消息包括如下至少一项：
终端信息；
终端辅助信息；

例如，终端向网络侧设备发送用于请求PEI和/或寻呼分组第二RRC消息，网络侧设备基于接收到的所述第二RRC消息，向终端发送系统消息或第一RRC消息，所述系统消息或第一RRC消息的消息内容如上所述，此处不再赘述。
本申请实施例中，终端能够主动向网络侧设备请求PEI和/或寻呼分组，进而网络侧设备向终端通过系统消息或RRC消息向终端指示PEI和/或寻呼分组的使用条件，以确保网络侧设备和终端对于PEI和/或寻呼分组的使用具有一致的理解。
为更好地理解，以下通过几个具体的实施例对本申请提供的技术方案进行具体说明。
实施例一
终端驻留在当前小区，终端接收网络侧设备发送的系统消息；若当前小区第一指示为不要求仅在终端最后使用的小区使用PEI和寻呼分组中的至少一项，或者当前小区接收到的系统消息中未包含第一指示，或者当前小区是终端被释放或被挂起的小区，则终端在此小区(也即当前小区)可以使用PEI 和/或寻呼分组。
实施例二
终端在cell1被释放或被挂起，然后重选到cell2，后来又小区选择或重选回到cell1。这种情况下，终端可以执行以下至少一项操作：
选择(Option)1：终端在cell1可以使用PEI和/或寻呼分组；进一步地，当前小区被认为是“最后使用的小区”，上述第一指示(也即是否仅在终端最后使用的小区使用PEI和寻呼分组中的至少一项)对于在当前小区被释放或挂起的终端不生效；
Option2：终端在cell1根据第一指示来确定是否使用PEI和/或寻呼分组；
Option3：终端自行决定是否在cell1使用PEI和/或寻呼分组。
实施例三
终端在cell1被释放或被挂起，然后重选到cell2，且在cell2被释放或被挂起，后来又小区选择或重选回到cell1。这种情况下，终端执行以下至少一项操作：
Option1：终端在cell1可以使用PEI和/或寻呼分组；进一步地，当前小区被认为是“最后使用的小区”；
Option2：终端在cell1根据第一指示来确定是否使用PEI和/或寻呼分组；
Option3：终端自行决定是否在cell1使用PEI和/或寻呼分组。
实施例四
终端接收RRC消息如释放或挂起，所述RRC消息指示以下至少一项：
-是否使用PEI和/或寻呼分组；
-当前小区是否是最后使用的小区(Last used cell)；
-第一指示。
进一步地，在网络侧设备发送RRC消息指示是否使用PEI和/或寻呼分组之前，终端发送RRC消息，用来请求使用PEI和/或寻呼分组；终端发送的RRC消息包括以下至少一项：
-终端信息；
-终端辅助信息；
-PEI使用请求信息；
-RRC恢复(resume)请求。
上述实施例中，网络侧设备可以灵活地配置终端使用PEI和/或寻呼分组，定义终端在小区选择或小区重选后的行为，以及在连接释放或挂起后的行为，有利于网络侧设备和终端对于PEI和/或寻呼分组的使用有一致的理解，来保证寻呼接收成功。
请参照图3，图3是本申请实施例提供的另一种寻呼指示方法的流程图， 如图3所示，所述方法包括以下步骤：
步骤301、网络侧设备向终端发送系统消息或第一RRC消息。
其中，所述系统消息或第一RRC消息包括如下至少一项：

用于指示所述终端驻留的当前小区是否是最后使用的小区；
第一指示，所述第一指示用于指示是否仅在所述终端最后使用的小区使用PEI和寻呼分组中的至少一项。
本申请实施例中，网络侧设备向终端发送系统消息或第一RRC消息，终端能够基于所述系统消息或第一RRC消息确定是否在当前小区使用PEI和/或寻呼分组。例如，若所述系统消息或第一RRC消息指示终端允许在当前小区使用PEI和/或寻呼分组，则所述终端在当前小区使用PEI和/或寻呼分组；或者，系统消息或第一RRC消息指示所述当前小区为最后使用小区，则终端可以是在当前小区使用PEI和/或寻呼分组；或者，所述系统消息或第一RRC消息还可以是包括第一指示，则终端基于所述第一指示确定是否在当前小区使用PEI和/或寻呼分组；或者，所述系统消息或第一RRC消息包括第一指示，以及还用于指示当前小区为最后使用的小区，则终端可以是基于第一指示在当前小区使用PEI和/或寻呼分组；等，本实施例不做具体赘述。
这样，网络侧设备能够通过系统消息或第一RRC消息来对终端是否在当前小区使用PEI和/或寻呼分组进行灵活配置，以确保网络侧设备和终端对于PEI和/或寻呼分组的使用具有一致的理解，保障寻呼接收成功。
可选地，所述方法还可以包括：
