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在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
当前，随着人们对速率、延迟、高速移动性、能效的追求以及未来生活 中业务的多样性、复杂性要求，第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)国际标准组织开始研发第五代移动通信技术(5th Generation Mobile Communication Technology，5G)。5G的主要应用场景包括增强移动超宽带(Enhanced Mobile Broadband，eMBB)、低时延高可靠通信(Ultra-reliable and Low Latency Communications，URLLC)、大规模机器类通信(Massive Machine Type Communication，mMTC)。
5G新空口(New Radio，NR)也可以独立部署，5G网络环境中，为了降低空口信令和快速恢复无线连接，快速恢复数据业务，定义一个新的RRC状态即RRC INACTIVE态，RRC INACTIVE态与RRC IDLE态和RRC激活(ACTIVE)态的区别如下：
RRC IDLE态：移动性为基于终端设备的小区选择重选，寻呼由核心网设备发起，寻呼区域由核心网设备配置。接入网设备侧不存在终端设备接入层(Access Stratum，AS)上下文，不存在RRC连接。
RRC CONNECTED态：存在RRC连接，接入网设备和终端设备存在终端设备AS上下文。网络侧知道终端设备的位置是具体小区级别的。移动性是网络侧控制的移动性。终端设备和接入网设备之间可以传输单播数据。
RRC INACTIVE态：移动性为基于终端设备的小区选择重选，存在核心网设备至新空口之间的连接，终端设备AS上下文存在某个接入网设备上，寻呼由无限接入网(Radio Access Network，RAN)触发，基于RAN的寻呼区域由RAN管理，网络侧知道终端设备的位置是基于RAN的寻呼区域级别的。
下面对于5G NR的paging机制进行说明。
Paging主要功能是使得网络能在终端设备的RRC IDLE态或者RRC INACTIVE态通过paging message寻呼终端设备，或者通过short message通知终端设备系统消息变更或者地震海啸/公共预警信息(适用于终端设备所有RRC状态)。
Paging包括由寻呼无线网络临时标识(Paging Radio Network Tempory Identity，P-RNTI)加扰的物理下行控制信道(Physical Downlink Control Channel，PDCCH)，以及由该PDCCH调度的物理下行共享信道(Physical Downlink Share Channel，PDSCH)。Paging message在PDSCH中传输，short message为8比特(bit)在PDCCH中。
对于处于RRC IDLE态或者RRC INACTIVE态的终端设备，由于终端设备与网络之间没有其他的数据通信，为了终端设备省电，终端设备可以非连续的监听paging信道，即采用paging非连续性接收(Discontinuous Reception，DRX)机制。在Paging DRX机制下，终端设备只需要在每个DRX周期内的一个PO期间监听paging。在TS 38.304中规定，PO是由paging搜索空间(search space)上的多个PDCCH监听时机(monitoring occasion)组成，一个PO包含X个PDCCH monitoring occasion，X等于主系统信息块(Master Information Block，MIB)中广播的同步信号块(Synchronization Signal Block， SSB)实际发送的数量。另外还有寻呼帧(Paging Frame，PF)的概念，PF指的是一个无线帧(固定10ms)，该无线帧可以包含多个PO或者是多个PO的起始位置。
Paging DRX的周期由系统广播中的公共周期和高层信令(NAS信令)中配置的专属周期共同决定，终端设备取两者中的最小周期为Paging的周期。从网络角度来看，一个paging DRX周期可以有多个PO，终端设备监听PO的位置跟该终端设备的标识(Identity document，ID)有关。具体的。某一个终端设备在一个Paging DRX中的PF的SFN编号通过公式(1)确定(TS 38.304)，某一个终端设备在一个Paging DRX中的PO位于一个PF内的编号Index(i_s)通过以下公式(2)确定(TS 38.304)。
(SFN+PF_offset)mod T＝(T div N)*(UE_ID mod N)  (1)
i_s＝floor(UE_ID/N)mod Ns      (2)
其中，T为终端设备接收paging的DRX周期，N为一个T内包含的PF个数，Ns为一个PF内包含的PO个数，PF_offset为用于确定PF的一个时域偏移量，UE_ID＝5G-S-TMSI mod 1024。
应理解，网络会广播1个默认的DRX周期，若RRC/高层为终端设备配置了终端设备专属的DRX周期，则将网络广播的DRX周期和RRC/高层配置的终端设备专属的DRX周期中最小的作为该终端设备的DRX周期。若RRC/高层没有为终端设备配置UE专属的DRX周期，则将网络广播的DRX周期作为该终端设备的DRX周期。
需要说明的是，终端设备基于上述公式计算出PF、PO的index以及PO中PDCCH monitoring occasion的数量之后，只需要通过相关配置参数知道该PO的第一个PDCCH monitoring occasion的起始位置，该起始位置通过高层信令配置。终端设备根据确定的PO来盲检paging消息。
下面对于寻呼虚警(Paging false alarm)进行说明。
由以上终端设备确定PO可以看出，其PO的确定与终端设备的标识(UE_ID)有关，以及PF、PO总数有关。在系统中的终端设备较多，网络不能把每个终端设备分配到不同的PO上时，就会存在多个终端设备对应一个PO的情况。若网络需要paging这个PO上的某一个终端设备，则有可能导致其他本来没有paging消息的终端设备额外进行盲检，主要包括盲检PDCCH以及对应的PDSCH。对于这些本来没有paging消息的终端设备来讲，这种错误的paging就是paging false alarm。
在R17的工作项目中，3GPP RAN对终端节能的进一步增强。其中一方面即通过设计增强的paging机制，来减少不必要的终端设备paging接收，从而减少paging虚警。
目前可以引入如下机制来减少paging虚警：
1.引入基于PDCCH设计的寻呼提前指示(Paging Early Indication，PEI)，即网络在PO之前发送PEI，终端设备根据接收到PEI指示来决定在相应的PO 上正常监听paging还是跳过paging监听。
2.引入基于终端设备分组的paging机制，即将分配到同一个PO上的多个终端设备进一步分组，网络可以指示paging消息是针对那个或者哪些终端设备组的，从而使其他终端设备分组的终端设备无需再接收paging消息。其中，Paging分组指示信息可以在PEI中携带。
3.对于基于终端设备分组的paging，终端设备所在的组标识(group ID)可以由核心网设备确定。若核心网设备未给终端设备分配一个group ID，则可以基于终端设备的标识确定group ID。
4.为了支持基于终端设备的标识的分组方式，接入网设备需要广播小区支持的基于终端设备的标识的paging分组个数。
5.为了便于支持基于核心网设备分配的paging分组方式，假设一个注册区域内的所有小区支持的基于核心网设备分配的paging分组个数相同，相关技术中未确定如何基于核心网设备分配paging分组个数。
6.一个小区可以同时支持基于终端设备的标识的paging分组和基于核心网设备分配的paging分组，两种分组方式下对应的grouping ID没有重叠。PEI中的一个paging分组指示比特对应一个基于终端设备ID的paging分组或一个基于核心网设备分配的paging分组。
此外，需要说明的是，对于分组Paging，一个PO支持的最大分组个数为8。
下面对于低能力(RedCap)终端进行说明。
在NR所支持的eMBB、URLLC等应用场景之外，工业无线传感器、视频监控和可穿戴设备等终端物联网用例对5G终端提出了复杂度和成本降低、尺寸间校和能耗更低等新的需求。为此，R17NR中引入RedCap终端，目前RedCap终端主要有三个场景。
工业无线传感器(Industrial Wireless Sensors)：与URLLC相比，工业无线传感器，具有相对低要求的时延和可靠性。同时，工业无线传感器的成本和功耗也比URLLC和eMBB要低。该终端类型的主要需求和特征包括：通信可靠性99.99％，端到端时延<100ms，参考数据速率小于2Mbps并以上行业务为主，设备静止，要求电池使用时间长达几年。对于用于安全相关的传感器，时延要求更低，为5～10ms。
视频监控(Video surveillance)：主要用在智慧城市，工业工厂等视讯监控。智能城市中数据收集和处理，以便于更有效的进行城市资源的监测和控制，给城市居民提供更有效的服务。视频监控以上行业务为主，其他主要需求还包括：普通分辨率视频的参考速率为2～4Mbps，时延低于500ms，通信可靠性99％～99.9％，高清视频的速率需求为7.5～25Mbps。
可穿戴设备(Wearables)：包括智能手表，智能手环，电子健康设备以及一些医疗监测设备等。可穿戴设备的一个共性就是小尺寸的设备。可穿戴设备的关键指标要求包括：下行、上行参考速率分别为5～50Mbps和2～5Mbps； 下行、上行峰值速率分别为150Mbps和50Mbps。要求电池能工作数天甚至1～2周。
下面针对NR RedCap的eDRX机制进行说明。
针对RedCap引入空闲态或非激活态下的eDRX机制，从而达到终端省电，延长电池寿命的目的。
应理解，对于RRC IDLE态的终端设备，eDRX由核心网设备配置，可支持的最大CN eDRX周期为10485.76s。对于RRC INACTIVE态，RAN可以参考核心网设备eDRX配置为该终端设备配置一个RAN eDRX周期，可支持的最大RAN eDRX周期为10.24s。对于RRC IDLE态和RRC INACTIVE态的终端设备，如果核心网设备配置的eDRX周期超过了10.24s，则终端设备在一个eDRX周期内的寻呼时间窗(Paging Time Window，PTW)时间窗内在自己的PO上监听寻呼。对于RRC IDLE态和RRC INACTIVE态的终端设备，如果eDRX周期未超过10.24s，则寻呼监听不使用PTW和PH等。
下面对于现有的终端设备的标识的确定方法进行说明。
现有技术中，终端设备基于终端设备的标识计算终端设备对应的PF和PO位置。其中，终端设备的标识UE_ID＝5G-S-TMSI mod 1024。其中，N的最大值为256，Ns的最大值为4，因此，一个DRX周期T内包含的最大PO个数为256*4＝1024。图1为本申请实施提供的一种现有的PF和PO的映射关系示意图。如图1所示，使用5G-S-临时移动用户识别码(Temporary Mobile Subscriber Identity，TMSI)的10个最低有效位(Least Significant Bit，LSB)(即5G-S-TMSI mod 1024)，可以将不同终端设备分布到不同的PF/PO上。
在引入eDRX之后，由于N的最大值为1024(对应于T＝10.24s的情况)，因此，一个T内包含的最大PO个数为4096。此时，为了能够将不同的UE分布到不同的PF和/或PO上，对于eDRX,可以将UE ID定义为5G-S-TMSI mod 4096。
同时，对于基于分组的paging，为了将映射到相同PO上的不同UE分布到不同Paging分组上，可以将UE ID定义为5G-S-TMSI mod X,其中X等于1024*可支持的最大分组个数，但并未考虑eDRX的情况。
因此，当支持eDRX和分组Paging结合使用时，对于配置eDRX且支持分组paging的终端设备，若采用现有的终端设备的标识的定义方式，可能无法准确确定出待监听寻呼的信息，进而可能出现部分分组索引(subgrouping ID)始终得不到使用的情况。
为解决上述问题，本申请实施例提供了一种通信方法及装置，若终端设备配置有eDRX且支持分组寻呼，则根据eDRX的预设周期和/或一个寻呼时机支持的最大分组个数确定终端设备的标识，进而可以保证基于eDRX和分组寻呼对应的终端设备的标识准确确定出目标寻呼的信息。
下面对于本申请的应用场景进行举例说明。
图2为本申请实施例提供的一种通信方法的场景示意图。如图2所示， 终端设备101和网络设备102之间通信。网络设备102在终端设备101的RRC IDLE态或者RRC INACTIVE态可以寻呼终端设备101。相应的，终端设备101可以监听网络设备102的寻呼。当终端设备101配置有扩展的非连续接收eDRX且支持分组寻呼时，终端设备101可以基于eDRX的预设周期和/或一个寻呼时机支持的最大分组个数确定终端设备101的标识，并根据终端设备101的标识确定网络设备102的寻呼的信息。
其中，终端设备101包括但不限于卫星或蜂窝电话、可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(Personal Communications System，PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(Global Positioning System，GPS)接收器的PDA；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端设备可以指接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、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)、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、5G网络中的终端设备或者未来演进的PLMN中的终端设备等。
网络设备102可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。可选地，该网络设备102可以是GSM系统或CDMA系统中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
下面以终端设备或网络设备等通信设备为例，以具体地实施例对本申请实施例的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
图3为本申请实施例提供的一种通信方法的流程示意图。本申请实施例的执行主体为终端设备，涉及的是终端设备如何确定待监听的目标寻呼的信息的过程。如图3所示，该方法包括：
S201、若终端设备配置有扩展的非连续接收eDRX且支持分组寻呼，则根据eDRX的预设周期和/或一个寻呼时机支持的最大分组个数确定终端设备的标识。
在本申请中，当终端设备配置有eDRX且支持分组寻呼时，终端设备需 要避免使用现有的终端设备的标识的确定方法，以免获取到不准确的目标寻呼的信息，造成寻呼分组索引部分得不到使用的情况。
需要说明的是，终端设备支持分组寻呼，可以理解为终端设备具备分组寻呼的能力，进一步的，在一些实施例中，终端设备可以具备基于终端设备的标识的分组寻呼的能力。
应理解，本申请实施例对于eDRX的预设周期不做限制，可以根据实际情况具体设置。示例性的，eDRX的预设周期可以设置为10.24s。相应的，一个eDRX的预设周期内包含的PF的个数可以为1024，由于一个PF中包含的PO个数的最大值为4，一个eDRX的预设周期内包含的最大PO个数为4*1024＝4096。
需要说明的是，本申请实施例涉及的终端设备配置的eDRX，可以为上述eDRX的预设周期，也可以小于eDRX的预设周期，本申请实施例对此不做限制。示例性的，终端设备配置的eDRX可以为5.12s或10.24s。
相应的，本申请实施例对于一个寻呼时机支持的最大分组个数也不做限制，在一些实施例中，一个寻呼时机支持的最大分组个数可以为可支持的基于终端设备的标识的最大分组个数。
应理解，本申请实施例对于一个寻呼时机支持的最大分组个数的确定方式也不做限制，在一些实施例中，一个寻呼时机支持的最大分组个数可以由网络设备指示或通过预定义信息确定，示例性的，一个寻呼时机支持的最大分组个数可以定义为8。
应理解，本申请实施例对于如何确定终端设备的标识不做限制，可以根据网络设备是否为终端设备配置寻呼分组索引而采用两种不同的方式。
在第一种方式中，终端设备使用终端设备的标识确定寻呼分组索引，相应的，终端设备的标识可以为第一标识，该第一标识是根据eDRX的预设周期包含的最大寻呼时机个数和一个寻呼时机支持的最大分组个数确定的。示例性的，上述第一标识UE ID1可以采用公式(3)确定。
UEID1＝5G-S-TMSImod(4096*Ng_max)    (3)
其中，4096为一个eDRX的预设周期内包含的最大PO个数，Ng_max为一个寻呼时机支持的最大分组个数。
需要说明的是，公式(3)中eDRX的预设周期的取值为10.24s，在实际应用中，可以采用其他取值，公式(3)并不构成限制。
需要说明的是，本申请实施例对于终端设备何时确定使用终端设备的标识确定寻呼分组索引不做限制，可以包括但不限于以下两种情况。在一种情况中，网络未给终端设备分配分组寻呼索引，则终端设备基于终端设备的标识确定寻呼分组索引。在另一种情况中，核心网设备给终端设备分配了分组寻呼索引，但当前小区的接入网设备不支持核心网设备分配的寻呼分组索引，则终端设备在当前小区也需要使用基于终端设备的标识确定的寻呼分组索引。
在第二种方式中，网络设备向终端设备发送寻呼分组索引，且终端在当 前小区使用所述网络设备分配的寻呼分组索引监听寻呼，相应的，终端设备的标识可以为第二标识，该第二标识是根据eDRX的预设周期包含的最大寻呼时机个数确定的。示例性的，上述第二标识UE ID2可以采用公式(4)确定。
UE ID1＝5G-S-TMSImod(4096)     (4)
需要说明的是，上述为终端设备配置寻呼分组索引的网络设备可以为核心网设备(Core Network，CN)。
S202、终端设备根据终端设备的标识确定待监听的目标寻呼的信息。
在本步骤中，当终端设备确定终端设备的标识后，可以根据终端设备的标识确定待监听的目标寻呼的信息。
其中，目标寻呼的信息可以包括寻呼帧和寻呼时机。
应理解，本申请实施例对于如何确定寻呼帧和寻呼时机不做限制，示例性的，可以采用公式(5)确定寻呼帧PF对应的系统帧号(System Frame Number，SFN)编码，采用公式(6)确定寻呼时机PO位于一个PF内的编码i_s。
(SFN+PF_offset)mod T＝(T div N*(UE ID mod N)     (5)
i_s＝floor(UEID/N)mod Ns     (6)
其中，UE ID为终端设备的标识，其可以为第一标识UE ID1，也可以为第二标识UE ID2，本申请实施例对此不做限制。T为终端设备用于监听寻呼的DRX周期。N为一个T内包含的PF个数。Ns为一个PF内包含的PO个数。PF_offset为用于确定PF的一个时域偏移量。
在一些实施例中，目标寻呼的信息可以包括终端设备所在的寻呼分组索引。相应的，对于配置了eDRX且支持分组寻呼的终端设备，若该终端设备的标识确定其所在寻呼分组，则该终端设备可以使用第一标识确定其所属的寻呼分组索引。
本申请实施例对于如何基于第一标识确定终端设备所在的寻呼分组索引不做限制，示例性的，可以通过公式(7)确定。
subgrouping ID＝floor(UE ID1/(N*Ns))mod Ng   (7)
其中，subgrouping ID为寻呼分组索引，Ns为一个PF中包含的PO个数，Ng为基于终端设备的标识进行寻呼分组的寻呼分组个数，Ng可以由网络设备通过广播的方式通知给终端设备，UE ID1和N的含义和取值与公式(5)和公式(6)一致，在此不再赘述。
在另一些实施例中，网络设备可以为终端设备配置寻呼分组索引，则相应的，对于配置了eDRX且支持分组寻呼的终端设备，若终端设备在当前小区使用网络设备分配的寻呼分组索引，终端设备无需再通过终端设备的标识确定寻呼分组索引，可以直接使用网络设备配置的寻呼分组索引。
在本申请中，当终端设备确定寻呼分组索引后，终端设备可以基于寻呼分组索引监听分组寻呼。
可选的，在本申请实施例中，终端设备所在的小区支持eDRX和分组寻 呼。
可选的，在本申请实施例中，上述分组寻呼包括基于终端设备的标识的分组寻呼。
下面对于目标寻呼的信息的映射关系进行说明。
图4为本申请实施例提供的一种第一标识对应的目标寻呼的信息的映射关系示意图，图5为本申请实施例提供的一种第二标识对应的目标寻呼的信息的映射关系示意图。如图4所示，N设置为1024，Ns设置为4，Ng设置为2，则相应的，PF包括PF1-PF1024，PO包括PO1-PO4，subgrouping ID包括subgrouping 0和subgrouping 1。如图5所示，N设置为1024，Ns设置为4，则相应的，PF包括PF1-PF1024，PO包括PO1-PO4，subgrouping ID的取值有核心网设备CN配置。
本申请实施例提供的通信方法，若终端设备配置有扩展的非连续接收eDRX且支持分组寻呼，则终端设备根据终端设备的标识确定待监听的目标寻呼的信息。其中，终端设备的标识是根据eDRX的预设周期和/或一个寻呼时机支持的最大分组个数确定的。通过该方式，可以基于eDRX的预设周期和/或一个寻呼时机支持的最大分组个数确定终端设备的标识，从而使得配置有eDRX且支持分组寻呼的终端设备，可以基于eDRX和分组寻呼对应的终端设备的标识准确确定出目标寻呼的信息。
在上述实施例的基础上，下面基于网络设备是否为终端设备分配分组索引，对两种终端设备的标识的确定方法进行具体说明。

S302、终端设备根据第一标识确定待监听的寻呼帧、寻呼时机和/或寻呼分组索引。
在本实施例中，对于配置了eDRX且支持分组寻呼的终端设备，终端设备基于第一标识计算其对应的PF和PO。对于基于终端设备的标识确定其所在寻呼分组的终端设备，终端设备使用第一标识确定其所属的寻呼分组索引。
需要说明的是，第一标识、寻呼帧、寻呼时机和寻呼分组索引的计算公式可参考公式(3)-(7)，在此不在赘述。
可选的，上述PF和PO的计算公式适用于配置了eDRX且具备分组寻呼能力的终端设备。

S404、终端设备根据第二标识确定待监听的寻呼帧和寻呼时机。
S405、终端设备根据网络设备配置的寻呼分组索引听分组寻呼。
在本实施例中，对于配置了eDRX且支持分组寻呼的终端设备，若网络设备为其分配了寻呼分组索引且该终端设备在当前小区使用网络设备分配的寻呼分组索引，则所述终端设备基于第二标识D计算其对应的PF和PO。
可选的，上述PF和PO的计算公式适用于配置了eDRX且网络设备为其分配了寻呼分组索引的终端设备。
可选的，上述PF和PO的计算公式适用于配置的eDRX周期为5.12s和/或10.24s，且网络设备为其分配了寻呼分组索引的终端设备。
可选的，上述PF和PO的计算公式适用于配置了eDRX且终端设备在当前服务小区使用网络设备为其分配的寻呼分组索引监听分组寻呼的情况。
可选的，上述PF和PO的计算公式适用于配置的eDRX周期为5.12s和/或10.24s，且终端设备在当前服务小区使用网络设备为其分配的寻呼分组索引监听分组寻呼的情况。
