如图1所示，本公开实施例提供的一种通信方法可应用于无线通信系统100，该无线通信系统可以包括网络设备101和用户设备102。其中，用户设备102被配置为支持载波聚合，并可连接至网络设备101的多个载波单元，包括一个主载波单元以及一个或多个辅载波单元。
应理解，以上无线通信系统100既可适用于低频场景，也可适用于高频场景。无线通信系统100的应用场景包括但不限于长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)系统、全球互联微波接入(worldwide interoperability for micro wave access，WiMAX)通信系统、云无线接入网络(cloud radio access network，CRAN)系统、未来的第五代(5th-Generation，5G)系统、新无线(new radio，NR)通信系统或未来的演进的公共陆地移动网络(public land mobile network，PLMN)系统等。
以上所示用户设备102可以是终端(terminal)、接入终端、终端单元、终端站、移动台(mobile station，MS)、远方站、远程终端、移动终端(mobile terminal)、无线通信设备、终端代理或终端设备等。该用户设备102可具备无线收发功能，其能够与一个或多个通信系统的一个或多个网络设备进行通信(如无线通信)，并接受网络设备提供的网络服务，这里的网络设备包括但不限于图示网络设备101。
其中，用户设备102可以是蜂窝电话、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)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处理设备、车载设备、可穿戴设备、未来5G网络中的终端设备或者未来演进的PLMN网络中的终端设备等。

比如，网络设备101包括但不限于：5G中的下一代基站(gnodeB，gNB)、LTE系统中的演进型节点B(evolved node B，eNB)、无线网络控制器(radio network controller，RNC)、WCDMA系统中的节点B(node B，NB)、CRAN系统下的无线控制器、基站控制器(basestation controller，BSC)、GSM系统或CDMA系统中的基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved nodeB，或home node B，HNB)、基带单元(baseband unit，BBU)、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)或移动交换中心等。
本公开实施例提供一种通信方法，参照图2，图2是根据一示例性实施例示出的一种 通信方法的交互流程图，如图2所示，该方法包括步骤S201～S202，具体的：
步骤S201，网络设备101向用户设备102发送寻呼消息，寻呼消息包括被寻呼的用户设备关联的组标识。
在一些可能的实施方式中，用户设备102可以是基于Ambient IoT的用户设备，或称Ambient IoT终端。
可以理解的，在Ambient IoT的场景下Ambient IoT终端的连接密度更高，例如Ambient-IoT类型通信网络中网络设备101需支持连接更多数量的用户设备102。
在一些可能的实施方式中，组标识用于标识一组用户设备102，该一组用户设备102包括一个或一个以上的用户设备102如Ambient IoT终端。
在一些可能的实施方式中，组标识包括不同类型的用户设备组的组标识，其中，不同类型的用户设备组是根据不同的用户设备属性划分的。其中，用户设备属性包括但不限于用户设备业务类型、位置相关的属性或者服务供应商等，可以参见下述实施例的描述。
在一些可能的实施方式中，用户设备102所关联的组标识可以是网络设备101配置的，或者协议定义的，或者该用户设备102根据协议定义的方式确定的。
在一些可能的实施方式中，单个的用户设备102可能与一个或一个以上的组标识关联，根据寻呼消息中的组标识可以确定网络设备101所寻呼的一个或一个以上的用户设备102。
在一些可能的实施方式中，网络设备101可以周期性的广播寻呼消息。
在一些可能的实施方式中，网络设备101可发送寻呼下行控制信息(paging DCI)，通过paging DCI调度物理下行共享信道(Physical Downlink Shared Channel，PDSCH)，在PDSCH中承载寻呼消息。
可以理解的，paging DCI是由寻呼无线网络临时标志(Paging Radio Network Temporary Identity，P-RNTI)。
步骤S202，用户设备102接收该寻呼消息。
在一些可能的实施方式中，该用户设备102可以是处于RRC空闲态或者RRC非激活态的任一用户设备102，即任一处于RRC空闲态或RRC非激活态的用户设备102在寻呼场景下，均可以参照本公开实施例的描述。
在一些可能的实施方式中，用户设备102可以是周期性的监听寻呼消息。
在一些可能的实施方式中，用户设备102根据网络设备101的配置，获知自身对应的寻呼时机(paging occasion，PO)，该PO为周期出现。每个用户设备102对应一套周期的PO资源，或者多个用户设备102对应同一套周期的PO资源。
在一些可能的实施方式中，用户设备102监听自身对应的PO中是否存在paging DCI。若监听到paging DCI，且该paging DCI中设定信息域指示该paging DCI调度了包含寻呼消息的PDSCH，用户设备102则可以根据paging DCI的指示接收和解调PDSCH。该PDSCH中承载的寻呼消息中，包含用户设备102关联的组标识。其中，设定信息域例如是Short Messages Indicator信息域。
可以理解的，若用户设备102没有监听到paging DCI，或者paging DCI的设定信息域指示没有寻呼消息时，用户设备102可以不去接收和解调PDSCH，此场景下表明用户设备102可能尚未被寻呼。
步骤S203，用户设备102根据寻呼消息确定是否发起随机接入。
在一些可能的实施方式中，处于RRC空闲态或者RRC非激活态的用户设备102在获得寻呼消息后，可根据寻呼消息中所指示的组标识确定是否发起随机接入。
在一示例中，若寻呼消息中指示的被寻呼的用户设备集合包括该用户设备102，用户设备102可以发起随机接入，以进入RRC连接态(CONNECTED)与网络设备101进行正常通信。其中，根据寻呼消息确定被寻呼的用户设备集合的方式可以参见下述实施例的描述。
本公开实施例中，网络设备101向用户设备102发送寻呼消息，以告知用户设备被寻呼用户设备关联的组标识。其中，组标识可以是按照不同用户设备属性划分的多种类型用户设备组的组标识，从而在以组标识确定被寻呼的用户设备的过程中，网络设备101一次可寻呼更多类型或更多维度用户设备组中的用户设备102，提升寻呼的效率，更适应用户设备102连接密度高的通信场景，例如包含不同类型的多种用户设备组的连接场景。
本公开实施例提供一种通信方法，该方法被网络设备101执行。参照图3，图3是根据一示例性实施例示出的一种通信方法的流程图，如图3所示，该方法包括步骤S301，具体的：
步骤S301，网络设备101向用户设备102发送寻呼消息，寻呼消息包括被寻呼的用户设备关联的组标识。
在一些可能的实施方式中，网络设备101可以周期性的广播寻呼消息。
在一些可能的实施方式中，网络设备101可发送paging DCI，通过paging DCI调度PDSCH，在PDSCH中承载寻呼消息。
在一些可能的实施方式中，组标识用于标识一组用户设备102，该一组用户设备102包括一个或一个以上的用户设备102。其中，用户设备102为高连接密度场景下的用户设备102。
在一些可能的实施方式中，组标识包括不同类型的用户设备组的组标识，其中，不同类型的用户设备组是根据不同的用户设备属性划分的。
其中，网络设备101可以根据不同类型的用户设备属性对用户设备102进行分类。在依据每个类型的用户设备属性对用户设备102进行分类而产生的用户设备分组中，可能包含一个或多个用户设备组，每个设备组包含至少一个用户设备102。
在一些可能的实施方式中，用户设备属性为以下一种：
服务提供商；
用户设备的地理位置；
用户设备的优先级；
业务类型。
在一示例中，根据不同类型的用户设备属性，将用户设备102划分成了不同类型的用户设备组，例如，用户设备组包括第一类型组、第二类型组、第三类型组和第四类型组。
本示例中，第一类型组是按照服务提供商划分的，即第一类型组中可包含多个UE组，多个UE组对应不同的服务提供商，每个UE组ID可表示该UE组对应的服务提供商。例如，第一类型组包括UE组1和UE组2，UE组1对应第一服务提供商，UE组2对应第二服务提供商。
第二类型组是按照用户设备的地理位置划分的，即第二类型组中可包含多个UE组，多个UE组对应不同的地理位置，每个UE组ID可表示该UE组对应的地理位置。例如，第二类型组包括UE组3和UE组4，UE组3对应第一地理位置，UE组4对应第二地理位置。可以理解的，地理位置可以是指位于不同范围的地理区域，或者指位于不同基站覆盖范围。
第三类型组是按照用户设备的优先级划分的，即第三类型组可包含多个UE组，多个UE组对应不同的优先级，每个UE组ID可表示该UE组对应的优先级。例如，第三类型组包括UE组5和UE组6，UE组5对应第一优先级，UE组6对应第二优先级。其中，用户设备102的优先级可以是网络设备101预先配置的。
第四类型组是按照业务类型划分的，即第四类型组可包含多个UE组，多个UE组对应不同的业务类型，每个UE组ID可表示该UE组对应的业务类型。例如，第四类型组包括UE组7和UE组8，UE组7对应第一业务类型，UE组8对应第二业务类型。
可以理解的，本公开实施例旨在对用户设备属性进行阐述而非限定，例如在上述列举的几项用户设备属性之外，用户设备属性还可以包括更多种：例如用户设备的工作环境(温度、湿度等)属性，又例如用户设备的移动速度属性，等等。总之，依据不同类型的用户设备属性可以对用户设备进行分类，产生各个类型的用户设备组划分。
在一些可能的实施方式中，用户设备102与一个或多个组标识关联。
在一示例中，用户设备102与一个组标识关联时，该组标识对应的UE组可能是第一类型组、第二类型组、第三类型组和第四类型组中一种类型的UE组。
在另一示例中，用户设备102关联多个组标识时，该多个组标识可以是不同类型的组标识。例如，用户设备102关联的多个组标识对应的UE组，可能第一类型组、第二类型组、第三类型组和第四类型组中至少两种类型的UE组。
在一些可能的实施方式中，用户设备102关联的组标识为协议定义的，或者网络设备101配置的，或者核心网设备配置的。
在一示例中，协议可以定义确定组标识的方法或计算方式，用户设备102根据协议定义的方法或计算方式确定自身对应的组标识。
在另一示例中，在步骤S301之前，网络设备101或者核心网设备为用户设备102配置好组标识。
其中，核心网设备通过网络设备101与用户设备102连接，因此可通过网络设备101向用户设备102配置组标识。
本公开实施例中，网络设备101向用户设备102发送寻呼消息，以告知用户设备被寻呼用户设备的组标识。其中，组标识可以是按照不同用户设备属性划分的多种类型用户设备组的组标识，从而在以组标识确定被寻呼的用户设备的过程中，网络设备101一次可寻呼更多类型或更多维度用户设备组的用户设备102，提升寻呼的效率，更适应用户设备102连接密度高的通信场景，例如包含不同类型的多种用户设备组的连接场景。
本公开实施例提供一种通信方法，该方法被网络设备101执行。该方法包括步骤S301，具体的：
步骤S301，网络设备101向用户设备102发送寻呼消息，寻呼消息包括被寻呼的用户设备关联的组标识。
其中，寻呼消息包括一个或多个被寻呼的用户设备集合，以及每个被寻呼的用户设备集合对应的至少一种类型用户设备组的组标识，每一个被寻呼的用户设备集合为：根据对应的至少一种类型用户设备组的组标识确定的。
在一些可能的实施方式中，寻呼消息可以通过直接或间接的方式指示该被寻呼的用户设备集合。该被寻呼的用户设备集合可以包含至少一个用户设备102。
在一些可能的实施方式中，网络设备101可以一次寻呼一个或多个用户设备集合，并可通过寻呼消息指示每个被寻呼的用户设备集合所对应的至少一种类型的UE组的组标识。
在一些可能的实施方式中，至少一种类型UE组可以是根据用户设备属性划分的。结合前述实施例的描述，至少一种类型用户设备组可以包括：第一类型组、第二类型组、第三类型组和第四类型组中的至少一项。
其中，第一类型组是按照服务提供商划分的，第二类型组是按照用户设备的地理位置划分的，第三类型组是按照用户设备的优先级划分的，第四类型组是按照业务类型划分的。
在一些可能的实施方式中，每一个被寻呼的用户设备集合为：根据对应的至少一种类型用户设备组的组标识所关联用户设备102的交集确定的。
在一示例中，每个被寻呼的用户设备集合包括：与对应的至少一种类型用户设备组中全部类型用户设备组的组标识均关联的用户设备。
为便于理解本公开实施例，以下列举一具体示例：
第一个示例：
网络设备101通过寻呼消息指示如下两个被寻呼的用户设备集合：
被寻呼的用户设备集合1{第一类型组0，第二类型组3，第三类型组1，交集}；
被寻呼的用户设备集合2{第一类型组0，第三类型组4，交集}；
其中，在被寻呼的用户设备集合1中指示了被寻呼用户设备所关联的三个类型UE组的组标识，即第一类型组0，第二类型组3和第三类型组1。该被寻呼的用户设备集合1中还指示了确定该集合的方式，即该三个类型UE组的组标识所关联用户设备102的交集。
本示例中，与第一类型组0，第二类型组3和第三类型组1三个组标识均关联的用户设备102所构成的集合，为被寻呼的用户设备集合1。相似的，与第一类型组0和第三类型组4两个组标识均关联的用户设备102所构成的集合，为被寻呼的用户设备集合2。
对于用户设备102而言，其可接收网络设备101预先配置的组标识，例如：
UE1关联的组标识包括：第一类型组0，第二类型组3，第三类型组1；
UE2关联的组标识包括：第一类型组0，第二类型组3；
UE3关联的组标识包括：第一类型组0，第三类型组4；
UE4关联的组标识包括：第一类型组0，第二类型组3，第三类型组4；
UE5关联的组标识包括：第一类型组0；
UE6关联的组标识包括：第一类型组0，第二类型组3，第四类型组1，第三类型组4。
在UE1～UE6中，与第一类型组0，第二类型组3和第三类型组1三个组标识均关联的用户设备102即被寻呼的用户设备集合1包括UE1和UE6，则UE1和UE6均被寻呼。与第一类型组0和第三类型组4两个组标识均关联的用户设备102即被寻呼的用户设备集合2包括UE3、UE4和UE6，则UE3、UE4和UE6均被寻呼。
由此，本示例中网络设备101通过一个寻呼消息寻呼了UE1、UE6、UE3和UE4。
在一些可能的实施方式中，每一个被寻呼的用户设备集合为：根据对应的至少一种类型用户设备组的组标识所关联用户设备102的并集确定的。
在一示例中，每个被寻呼的用户设备集合包括：与对应的至少一种类型用户设备组中任一类型用户设备组的组标识关联的用户设备。
为便于理解本公开实施例，以下列举一具体示例：
第二个示例：
网络设备101通过寻呼消息指示如下两个被寻呼的用户设备集合：
被寻呼的用户设备集合3{第二类型组1}；
被寻呼的用户设备集合4{第四类型组2}；
被寻呼的用户设备集合5{第一类型组0，第二类型组3}；
其中，在被寻呼的用户设备集合3中指示了被寻呼用户设备所关联的一个类型的UE组的组标识，即第二类型组1，该被寻呼的用户设备集合3为该类型UE组的组标识即第二类型组1所关联的用户设备102。相似的，被寻呼的用户设备集合4为第四类型组2关联的用户设备102。被寻呼的用户设备集合5包括与第一类型组0关联的用户设备102和与第二类型组3关联的用户设备102。
对于用户设备102而言，其可接收网络设备101预先配置的组标识，例如：
UE1’关联的组标识包括：第一类型组0，第二类型组1；
UE2’关联的组标识包括：第四类型组2；
UE3’关联的组标识包括：第二类型组2，第二类型组3；
UE4’关联的组标识包括：第一类型组0。
在UE1’～UE4’中，被寻呼的用户设备集合3包括UE1’，被寻呼的用户设备集合4包括UE2’，被寻呼的用户设备集合5包括UE3’和UE4’。
由此，本示例中网络设备101通过一个寻呼消息寻呼了UE1’、UE2’、UE3’和UE4’。
本公开实施例中，网络设备101通过寻呼消息，可以指示被寻呼的用户设备集合，从而用户设备102可以根据是否属于被寻呼的用户设备集合，确定自身是否被寻呼，在被寻呼时及时发起随机接入，以及时建立通信。
本公开实施例提供一种通信方法，该方法被网络设备101执行。参照图4，图4是根据一示例性实施例示出的一种通信方法的流程图，如图4所示，该方法包括步骤S401，具体的：
步骤S401，网络设备101向用户设备102发送寻呼消息，寻呼消息包括被寻呼的用户设备关联的组标识。
在一些可能的实施方式中，用户设备可以关联一个或多个组标识，在关联多个组标识时，该多个组标识可以不区分用户设备属性的类型。例如，该多个组标识对应的用户设备属性的类型均为业务类型，多个组标识分别对应不同的业务类型。
在一些可能的实施方式中，用户设备可以关联一个或多个组标识，在关联多个组标识时，该多个组标识分别对应不同类型的用户设备属性。此时，步骤S401的实施方式可以参见前述实施例的描述，例如参见步骤S301的实施方式，此处不再赘述。
步骤S402，网络设备101向用户设备102发送指示信息，指示信息用于指示被寻呼的用户设备集合的网络接入参数。
其中，指示信息中涉及的被寻呼的用户设备集合，包括网络设备101在寻呼消息中所寻呼的至少一个用户设备102。例如，被寻呼的用户设备集合可以通过寻呼消息中指示的组标识确定。
在一些可能的实施方式中，步骤S401和S402的实施方式仅作示意而非限定，例如指示信息可以包含在寻呼消息中，即通过发送寻呼消息同步发送该指示信息。
在一些可能的实施方式中，指示信息与寻呼消息分别发送，例如，网络设备101以广播的方式发送指示信息。处于RRC空闲态或非激活态的用户设备102可以接收该指示信息。
在一些可能的实施方式中，网络设备101可以一次寻呼一个或多个用户设备集合。
在一些可能的实施方式中，指示信息可以指示多个被寻呼的用户设备集合均适用的网络接入参数，或者为每个被寻呼的用户设备集合配置对应的网络接入参数。
在一些可能的实施方式中，指示信息包括每个被寻呼的用户设备集合对应的网络接入参数。
在一示例中，用户设备集合可以是通过寻呼消息指示的，例如，寻呼消息可以指示至少一个被寻呼的用户设备集合，以及每个被寻呼的用户设备集合对应的至少一种类型UE 组的组标识。根据至少一种类型UE组的组标识确定该被寻呼的用户设备集合。
本示例中，至少一种类型UE组可以是根据用户设备属性划分的。结合前述实施例的描述，至少一种类型用户设备组可以包括：第一类型组、第二类型组、第三类型组和第四类型组中的至少一项。其中，第一类型组是按照服务提供商划分的，第二类型组是按照用户设备的地理位置划分的，第三类型组是按照用户设备的优先级划分的，第四类型组是按照业务类型划分的。
本示例中，每个被寻呼的用户设备集合可以是：根据对应的至少一种类型UE组的组标识所关联用户设备102的交集或并集确定的。被寻呼的用户设备集合的确定方式可以参见前述实施例的描述，例如第一个示例和第二个示例的描述，此处不再赘述。
本示例中，网络设备101为每个被寻呼的用户设备集合配置对应的网络接入参数，例如，结合第一个示例，网络设备101为被寻呼的用户设备集合1配置第一套网络接入参数，为被寻呼的用户设备集合2配置第二套网络接入参数，且第一套网络接入参数与第二套网络接入参数不同。
在一些可能的实施方式中，网络接入参数包括以下至少一项：
随机接入的退避时长；
随机接入资源的频域位置；
随机接入资源的码域资源。
在一示例中，每个被寻呼的用户设备集合可对应配置一套网络接入参数，该一套网络接入参数可以包括上述退避时长、频域位置和码域资源。对于不同的被寻呼的用户设备集合，退避时长、频域位置和码域资源至少一项参数不同。
在一示例中，当网络设备101一次寻呼多个用户设备集合时，不同被寻呼的用户设备集合的网络接入参数不同，可以降低不同用户设备102在发起随机接入时的冲突。可以参见如下示例的描述。
在一可能的示例中，以两个被寻呼的用户设备集合为例进行说明，用户设备集合更多时可参照此示例描述。其中，若被寻呼的用户设备集合1和被寻呼的用户设备集合2的退避时长不同，则被寻呼的用户设备集合1中的用户设备102与被寻呼的用户设备集合2中的用户设备102将在不同的时段范围内发起随机接入，从而避免属于不同用户设备集合的用户设备102在相同或相似的时段范围内进行随机接入而造成随机接入资源冲突的情况。
例如，假设网络设备101为被寻呼的用户设备集合1配置的退避时长为0ms，为被寻呼的用户设备集合2配置的退避时长为40ms。被寻呼的用户设备集合1中的用户设备102在接收到寻呼消息后可以不需要退避，就近选择随机接入资源发起随机接入。被寻呼的用户设备集合2中的用户设备102则需要在收到寻呼消息之后等待退避时长40ms后，再去选择随机接入资源发起随机接入。
在一可能的示例中，以两个被寻呼的用户设备集合为例进行说明，用户设备集合更多时可参照此示例描述。其中，网络设备101可在频域上配置多个物理随机接入信道 (PhysicalRandom Access Channel，PRACH)，若被寻呼的用户设备集合1和被寻呼的用户设备集合2对应的随机接入资源的频域位置不同，则被寻呼的用户设备集合1和被寻呼的用户设备集合2将在对应于不同频域的PRACH)发起随机接入，从而降低或避免属于不同用户设备集合的用户设备102在随机接入过程中的冲突。
在一可能的示例中，仍以两个被寻呼的用户设备集合为例进行说明，用户设备集合更多时可参照此示例描述。其中，网络设备101可配置不同的码域资源，例如，被寻呼的用户设备集合1和被寻呼的用户设备集合2对应的前导码(preamble)集合不同，则被寻呼的用户设备集合1和被寻呼的用户设备集合2在发起随机接入的过程中，即使时域和/或频域资源位置存在冲突，也可以通过不同的前导码区分属于不同用户设备集合的用户设备102，从而降低或避免属于不同用户设备集合的用户设备102在随机接入过程中的冲突。
本公开实施例中，网络设备101可以为不同的被寻呼的用户设备集合配置对应的网络接入参数，从而可以避免或降低属于不同用户设备集合的用户设备102在随机接入过程中的资源冲突，提升随机接入的效率和成功率。
本公开实施例提供一种通信方法，该方法被用户设备102执行。参照图5，图5是根据一示例性实施例示出的一种通信方法的流程图，如图5所示，该方法包括步骤S501～S502，具体的：
步骤S501，用户设备102接收网络设备101发送的寻呼消息，寻呼消息包括被寻呼的用户设备关联的组标识。
在一些可能的实施方式中，该用户设备102可以是处于RRC空闲态或者RRC非激活态的任一用户设备102。
在一些可能的实施方式中，用户设备102根据网络设备101的配置，获知自身对应的PO，该PO为周期出现。每个用户设备102对应一套周期的PO资源，或者多个用户设备102对应同一套周期的PO资源。
在一些可能的实施方式中，用户设备102监听自身对应的PO中是否存在paging DCI。若监听到paging DCI，且该paging DCI中设定信息域指示该paging DCI调度了包含寻呼消息的PDSCH，用户设备102则可以根据paging DCI的指示接收和解调PDSCH。该PDSCH中承载的寻呼消息中，包含用户设备102关联的组标识。其中，设定信息域例如是Short Messages Indicator信息域。
在一些可能的实施方式中，组标识用于标识一组用户设备102，一个用户设备102可以关联一个或一个以上的组标识。

在一些可能的实施方式中，组标识包括不同类型的用户设备组的组标识，其中，不同类型的用户设备组是根据不同的用户设备属性划分的。
其中，网络设备101可以根据不同类型的用户设备属性对用户设备102进行分类。在 依据每个类型的用户设备属性对用户设备102进行分类而产生的用户设备分组中，可能包含一个或多个用户设备组，每个设备组包含至少一个用户设备102。
在一些可能的实施方式中，用户设备属性为以下一种：
服务提供商；
用户设备的地理位置；
用户设备的优先级；
业务类型。
例如，用户设备102与一个组标识关联时，该组标识对应的UE组可能是第一类型组、第二类型组、第三类型组和第四类型组中一种类型的UE组。
再例如，用户设备102关联多个组标识时，该多个组标识可以是不同类型的组标识。例如，用户设备102关联的多个组标识对应的UE组，可能第一类型组、第二类型组、第三类型组和第四类型组中至少两种类型的UE组。
其中，第一类型组是按照服务提供商划分的，第二类型组是按照用户设备的地理位置划分的，第三类型组是按照用户设备的优先级划分的，第四类型组是按照业务类型划分的。
可以理解的，本公开实施例旨在对用户设备属性进行阐述而非限定，例如在上述列举的几项用户设备属性之外，用户设备属性还可以包括更多种：例如用户设备的工作环境(温度、湿度等)属性，又例如用户设备的移动速度属性，等等。总之，依据不同类型的用户设备属性可以对用户设备进行分类，产生各个类型的用户设备组划分。
步骤S502，用户设备102根据寻呼消息确定是否发起随机接入。
在一些可能的实施方式中，若寻呼消息中指示的被寻呼的用户设备集合包括该用户设备102，用户设备102可以发起随机接入，以进入RRC连接态与网络设备101进行正常通信。其中，根据寻呼消息确定被寻呼的用户设备集合的方式可以参见前述实施例的描述。
本公开实施例中，用户设备102接收网络设备101发送的寻呼消息，以获知被寻呼的用户设备关联的组标识。从而在以组标识确定被寻呼的用户设备的过程中，网络设备101一次可寻呼更多的用户设备102，提升寻呼的效率，更适应用户设备102连接密度高的通信场景。
