而一个具体的寻呼包括两部分内容：寻呼通知短消息和寻呼消息，其中寻呼通知短消息用于指示是否存在寻呼消息，如P-RNTI或子分组中的PEI，即在PO时刻检测到P-RNTI或PEI中对应的子分组值为1，说明存在相应的寻呼消息，而其中的寻呼消息用于指示被寻呼的UE，如单播寻呼消息内容为UE ID，多播寻呼消息内容为TMGI。
针对相关技术中在发送PEI的过程中，UE如何接收子分组配置信息和PEI配置信息，以及已加入MBS会话和未加入MBS会话的UE如何检测PEI等问题，尚未提供有效的解决方案。

根据本发明的另一个实施例，还提供了一种信息发送装置，包括：第一发送模块，设置为发送寻呼提前指示PEI配置信息和子分组配置信息；第二发送模块，设置为在PEI时机发送PEI，并在寻呼时机发送寻呼消息。
根据本发明的又一个实施例，还提供了一种计算机可读存储介质，所述计算机可读存储介质中存储有计算机程序，其中，所述计算机程序被设置为运行时执行上述任一项方法实施例中的步骤。
根据本发明的又一个实施例，还提供了一种电子装置，包括存储器和处理器，所述存储器中存储有计算机程序，所述处理器被设置为运行所述计算机程序以执行上述任一项方法实施例中的步骤。
通过本公开，处于无线资源控制RRC非连接状态的用户设备UE通过系统广播消息接收子分组配置信息和寻呼提前指示PEI配置信息，已加入组播广播服务MBS会话的所述UE不检测PEI，在寻呼时刻检测寻呼消息；未加入MBS会话的所述UE根据所述子分组配置信息和PEI配置信息在PEI时刻检测PEI，如果所述PEI指示所述UE的所属子分组的寻呼消息存在，所述UE在寻呼时刻检测寻呼消息，从而解决了相关技术中在发送PEI的过程中，UE如何接收子分组配置信息和PEI配置信息，以及已加入MBS会话和未加入MBS会话的UE如何检测PEI的问题，达到了降低MBS寻呼信令负载，提高了MBS通信可靠性和网络运行性能的效果。

具体实施方式
下文中将参考示意图并结合实施例来详细说明本发明的实施例。
需要说明的是，本发明的说明书和权利要求书及上述示意图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
本发明实施例实施例中所提供的方法实施例可以在计算机终端、计算机第二节点或者类似的运算装置中执行。以运行在计算机终端上为例，图1是本发明实施例的一种信息接收方法的计算机终端的硬件结构框图。如图1所示，计算机终端可以包括一个或多个(图1中仅示出一个)处理器102(处理器102可以包括但不限于微处理器MCU或可编程逻辑器件FPGA等的处理装置)和用于存储数据的存储器104，其中，上述计算机终端还可以包括用于通信功能的传输设备106以及输入输出设备108。本领域普通技术人员可以理解，图1所示的结构仅为示意，其并不对上述计算机终端的结构造成限定。例如，计算机终端还可包括比图1中所示更多或者更少的组件，或者具有与图1所示不同的配置。
存储器104可用于存储计算机程序，例如，应用软件的软件程序以及模块，如本发明实施例中的信息接收方法对应的计算机程序，处理器102通过运行存储在存储器104内的计算机程序，从而执行各种功能应用以及数据处理，即实现上述的方法。存储器104可包括高速随机存储器，还可包括非易失性存储器，如一个或者多个磁性存储装置、闪存、或者其他非易失性固态存储器。在一些实例中，存储器104可进一步包括相对于处理器102远程设置的存储器，这些远程存储器可以通过网络连接至计算机终端。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
传输设备106用于经由一个网络接收或者发送数据。上述的网络具体实例可包括计算机终端的通信供应商提供的无线网络。在一个实例中，传输设备106包括一个网络适配器(Network Interface Controller，简称为NIC)，其可通过第一基站与其他网络设备相连从而可与互联网进行通讯。在一个实例中，传输设备106可以为射频(Radio Frequency，简称为RF)模块，其用于通过无线方式与互联网进行通讯。
在本实施例中提供了一种运行于上述计算机终端的信息接收方法，图2是根据本发明实施例的信息接收方法的流程图，如图2所示，该流程包括如下步骤：
步骤S202：处于无线资源控制RRC非连接状态的用户设备UE通过系统广播消息接收子分组配置信息和寻呼提前指示PEI配置信息，其中，已加入组播广播服务MBS会话的UE不检测PEI，在寻呼时刻检测寻呼消息；未加入MBS会话的UE根据所述子分组配置信息和PEI配置信息在PEI时刻检测PEI；
步骤S204：如果所述PEI配置信息指示所述UE的所属子分组的寻呼消息存在，所述UE在寻呼时刻检测寻呼消息。
需要说明的是，按照消息来源分类，寻呼可以分为：
5GC寻呼，来自于5GC的RRC_IDLE状态下，RRC_IDLE状态下当UE有下行数据到达时，5GC通过Paging寻呼消息通知UE；
RAN寻呼，来自于gNB，在RRC_INACTIVE状态下当UE有下行数据到达时，gNB通过RAN寻呼消息通知UE启动数传；
最终的寻呼消息下发都是由gNB通过空口下发给UE的。
寻呼消息由寻呼控制信道的PCCH逻辑信道承载，PCCH逻辑信道的数据块又是由寻呼信道PCH传输信道来承载，而PCH传输信道的数据块又是由物理下行共享信道PDSCH物理信道来承载的。由于PDSCH是下行共享物理信道，所以PDSCH上除了可以承载PCH传输信道之外，还可以承载DL-SCH传输信道。因此在接收寻呼消息之前，终端需要先去监听PDCCH物理信道，然后根据PDCCH物理信道上是否有携带P-RNTI(Paging-Radio Network Temporary Identifier)，来判断网络在本次寻呼周期是否有发送寻呼消息给自己。
Paging对应到物理层的信道为PDSCH，使用P-RNTI(值为0xFFFF)加扰的DCI format 1-0来调度PDSCH。
在NR中存在两种寻呼触发方式：核心网触发和基站触发，其中基站触发属于NR的新增内容。
为了降低RRC_IDLE/RRC_INACTIVE状态下UE的功耗，UE使用非连续接收方式(Discontinuous Reception，DRX)接收寻呼消息。这样可以使UE只在固定的时间内醒来接收paging消息，其余时间可以休眠以降低功耗，提升电池使用时间。每次唤醒的周期叫DRX cycle，一个DRX cycle内有若干个PF(Paging Frame)，一个PF对应若干个PO(Paging occasion)，
UE在一个DRX cycle内只醒来一次，进而监测一个PO。UE监视每个DRX周期的一个寻呼时机(PO)。PO是一组PDCCH监视时机，并且可以包括可以发送寻呼DCI的多个时隙(例如，子帧或OFDM符号)。一个寻呼帧(PF)是一个无线电帧，并且可以包含一个或多个PO或PO的起始点。
DRX cycle就表示UE检测Paging的周期，PF表示检测Paging的系统帧，PO表示检测paging的具体PDCCH monitoring occasions。
PDCCH monitoring occasion就是CORESET(Control Resource Set，一组物理资源集合)的时域位置，由paging search space指示，再加上该search space对应的CORESET，则可以具体确定接收P-RNTI加扰的PDCCH的CORESET时频资源，通过search space，UE可以确定一个以slot为单位的周期和偏移，以及每个周期内的持续slot个数和每个slot中的起始符号位置，从而可以确定所有的PDCCH monitoring occasions。再根据对应CORESET指示的信息，可以确定每个CORESET的时频资源。
在LTE中，一个PO就是一个子帧，UE计算得到PF和PO后就可以确定接收paging的子帧。而NR中search space不再是每一帧中的固定时域位置，即周期不再是以frame为单位 而是以slot为单位，所以需要通过上述search space确定PDCCH monitoring occasions，且由于每个PO要对应所有同步信号块SSB(Synchronization Signal Block)，所以每个PO都要包含S个PDCCH monitoring occasions，每个PDCCH monitoring occasion对应一个SSB，S即一个SSB set周期内的实际发送的SSB个数。所以在确定了PDCCH monitoring occasion和PF、PO后，还要将PDCCH monitoring occasions和每一个PO进行对应，从而才能确定某个UE的PDCCH monitoring occasions for paging。PF只是它所对应的所有PO的起点，一个PF及其后的系统帧直到下个PF为止，都可以有PO。两个PF之间由paging search space确定的PDCCH monitoring occasions都要进行编号，编号之后在组成PO时无需考虑帧和search space周期，组成一个PO的多个PDCCH monitoring occasion可以跨帧，可以跨周期。PO的不同其实是LTE paging和NR paging区别最大的地方。
即在5G中，一个PO不再是一个子帧而是若干个PDCCH monitoring occasions；
对应方式由SIB1中PDCCH-ConfigCommon中参数first PDCCH-MonitoringOccasion Of PO决定。从PF的第一个PDCCH monitoring occasion开始编号，如果该参数存在，则第(i_s+1)个PO的起始PDCCH monitoring occasion编号为该参数的第(i_s+1)个值，如果该参数不存在，则第(i_s+1)个PO的起始PDCCH monitoring occasion编号为i_s*S。
在5G中，一个PF仍然是一个系统帧，但PO不再只被包含在PF内，即一个PF不再是包含若干个PO，而是对应若干个PO，因为在两个PF之间的所有PDCCH monitoring occasions都是组成PO的PDCCH monitoring occasions。
通过上述步骤，处于无线资源控制RRC非连接状态的用户设备UE通过系统广播消息接收子分组配置信息和寻呼提前指示PEI配置信息，已加入组播广播服务MBS会话的所述UE不检测PEI，在寻呼时刻检测寻呼消息；未加入MBS会话的所述UE根据所述子分组配置信息和PEI配置信息在PEI时刻检测PEI，如果所述PEI指示所述UE的所属子分组的寻呼消息存在，所述UE在寻呼时刻检测寻呼消息，从而解决了相关技术中在发送PEI的过程中，UE如何接收子分组配置信息和PEI配置信息，以及已加入MBS会话和未加入MBS会话的UE如何检测PEI的问题，达到了降低MBS寻呼信令负载，提高了MBS通信可靠性和网络运行性能的效果。
可选的，上述RRC非连接状态，至少包括以下之一：未加入组播广播服务MBS会话的所述用户设备UE处于无线资源控制RRC空闲状态；未加入MBS会话的所述用户设备UE处于RRC不活跃状态；已加入MBS会话的所述用户设备UE处于RRC空闲状态；已加入MBS会话的UE处于RRC不活跃状态。
需要说明的是，上述多种RRC非连接状态的产生，是由于现有技术中采用了以下三种方法来提高寻呼成功率，分别包括：
子分组(Sub-grouping)：多个UE共享同一个寻呼机会(PO)，就会出现寻呼虚高的可能。采用子分组能够将一个PO中的UE划分为N个子组，以最大限度地减少错误寻呼报警。
寻呼提前指示(PEI)：通知UE是否接收下一个PO。基站通过系统广播消息指示PEI的配置信息，支持PEI的UE在每个DRX周期监视一个PEI机会PEI-O(PEI occasion)，一个PEI-O是一套PDCCH监视机会，包含多个时隙：具体的PEI内容由DCI format2_7指示，其中每个比特指示寻呼组或寻呼子组，当UE所属的组或子组比特为1，说明有针对UE的寻呼消息，则UE进一步读取相应的寻呼消息，若比特为0，说明没有针对相应的组或子组的寻呼消息。
跨时隙调度(Cross-slot scheduling)：这种寻呼增强可在PDCCH(PO)中包含的调度信息和PDSCH中携带的寻呼消息之间引入了延迟KO，允许UE只有在有寻呼消息时才能读取PDSCH。
其中，为了减少由于错误寻呼告警导致的5G终端功耗，可将监控同一个PO的终端(UE)组做进一步划分为多个子组。通过子分组，如果终端(UE)所属的子组如通过相关PEI指示的那样被寻呼，则UE应在其PO中监视PDCCH以进行寻呼。如果UE无法在小区中找到其带有PEI配置的子组ID，或者如果UE无法监控与其PO对应的关联PEI时机，则它应监控其PO中的寻呼。而寻呼子分组有以下两种方法：CN子分组(CN Subgrouping)、基于UE ID子分组(UE-ID based Subgrouping)。
图4-5分别给出了核心网和接入网的寻呼信令流程示意图，如图4和图5所示；在图5中RAN发起的寻呼中，gNB检测到处于RRC_INACTIVE态的UE有下行数据需要发送，则在RAN(RAN-based Notification Area)区域内发起对UE的寻呼。
MBS寻呼：5G R17引入的多播广播业务(MBS)主要针对公共安全、IoT应用、软件投递、TV Video、IPTV、直播带货等场景，比如，当遇到突发事件，可以让特定位置的大量用户同时接收到预警或通知。R17通过架构的建立、支持不同级别的服务、灵活的网络部署和操作、组播/广播空口技术等方式，支持组播/广播和现有单播系统灵活地复用共存。目前标准协议中组播Multicast通信针对RRC-connected UE，已加入多播组的UE在感兴趣接收的多播业务开始前可以为RRC_IDLE/RRC_INACTIVE状态，为了指示多播业务激活，基站可以在空口发送多播寻呼消息，多播寻呼和单播寻呼在相同的PO发送，多播寻呼消息的内容是多播业务会话标识，即临时移动组标识TMGI(Temporary Mobile Group Identity)，感兴趣接收组播业务的UE通过寻呼消息中的TMGI确定是否为所需的组播业务，如果是，则进入RRC连接态开始接收TMGI上承载的组播业务，否则，继续保持RRC_IDLE/RRC_INACTIVE态并检测相应的寻呼通知。
