技术领域
本申请涉及通信领域，尤其涉及一种通信方法及其相关设备。
背景技术
第五代(5th-Generation，5G)通信系统相对于长期演进(long term evolution，LTE)具有更高的载波频率，比如38GHz、72GHz等6GHz以上的载波频率，频率越高，信号的传播损耗越大，覆盖范围越小，目前一般采用波束赋型(beamforming，BF)技术来提高天线增益，波束赋型技术的波束具有一定的指向性，只能指向特定的终端。
当基站需要和终端建立连接时，基站会发起寻呼流程，基站在向终端发送寻呼消息之前，会先发送寻呼指示信息给终端，以提示终端在当前非连续接收(discontinuous reception，DRX)周期的寻呼时刻(paging moment，PO)是否需要进行寻呼消息的检测，若是，终端需要对每个波束方向的波束都进行检测。
若终端在当前DRX周期之外的其他DRX周期进行寻呼消息的检测，会加大终端检测寻呼消息的功耗。
发明内容
本申请提供了一种通信方法，用于根据寻呼指示信息以及分组值，确定终端在目标DRX周期内是否被网络设备寻呼。
本申请的第一方面提供了一种通信方法，包括：
从网络设备接收寻呼指示信息，该寻呼指示信息由网络设备配置，网络设备配置寻呼指示信息时需要知道该终端所在的分组值n，才能用寻呼指示信息指示该终端有没有被寻呼。其中，寻呼指示信息可以用来指示终端被网络设备寻呼了，或是指示终端没有被网络设备寻呼。
确定终端的分组值n，具体的，终端的分组值n可以由终端自己配置，也可以由网络设备配置，如果由网络设备配置，那么确定分组值n需要接收网络设备发送的寻呼指示信息后，利用寻呼指示信息计算得到终端的分组值n。其中，分组值n可以指示该终端为待寻呼终端组集合中第n个待寻呼终端组内的终端，n为大于或等于0的整数，待寻呼终端组集合包括至少一个待寻呼终端组。
在本申请中，将接入网络设备的终端分成了多个组，每个组称之为待寻呼终端组，分成的多个组的集合称之为待寻呼终端组集合，每一个待寻呼终端组中包括至少一个终端，某一终端被寻呼了，代表该终端所在的待寻呼终端组的终端都被寻呼了，反之亦然。
根据分组值n，确定寻呼指示信息中所指示的该第n个待寻呼终端组内的终端在目标 DRX周期内被寻呼的情况，寻呼指示信息可以指示终端在目标DRX周期内被网络设备寻呼了，或是指示终端在DRX周期内没有被网络设备寻呼。在本实现方式中，目标DRX周期为终端当前所在的DRX周期之后的DRX周期。
基于第一方面，在第一方面的第一种可实现方式中，如果终端在目标DRX周期内没有被网络设备寻呼，那么在目标DRX周期内不需要检测网络设备下发的寻呼消息。
在本实现方式中，在目标DRX周期内不检测寻呼消息可以降低检测寻呼消息的功耗。
基于第一方面或第一方面的第一种可实现方式，在第一方面的第二种可实现方式中，可以由终端侧将接入网络设备的终端分成了多个待寻呼终端组，那么终端分组值n由终端自己分配，也可以由网络设备侧将接入网络设备的终端分成了多个待寻呼终端组，那么终端分组值n由网络设备所分配。

根据当前DRX周期内寻呼时机的数目和终端的身份标识中任一项或者多项，以及待寻呼终端组集合中包含的待寻呼终端组的总数，确定分组值n。
在本实现方式中，待寻呼终端组的总数可以由寻呼指示信息确定，例如由寻呼指示信息的信息量大小确定。寻呼时机的数目可以为寻呼帧的数目，即当前DRX周期内PO的数目可以与当前DRX周期内寻呼帧的数目相同，寻呼时机PO的数目也可以为寻呼帧内PO的数目。
在本实现方式中，对分组值n的确定方式进行了说明，增加了方案的可实施性。
基于第一方面的第三种可实现方式，在第一方面的第四种可实现方式中，根据当前DRX周期内PO的数目和终端的ID中任一项或者多项以及待寻呼终端组的总数，确定终端的分组值n包括：
按照如下算法计算得到分组值n：分组值n＝(A/N)mod K，A为终端的ID字段中全部字段的信息量大小，也可以为终端的ID字段中部分字段的信息量大小，例如终端的ID字段中部分字段的信息量大小为8bit，那么A为8，N为当前DRX周期内PO的数目，K为待寻呼终端组的总数，A/N的结果值为进行取整数处理后的结果值，可以向上取整，也可以向下取整。
在本实现方式中，提供了终端分组值n的确定公式，增加了方案可实施性。
基于第一方面的第三种可实现方式，在第一方面的第五种可实现方式中，根据当前DRX周期内PO的数目和终端的ID中任一项或者多项以及待寻呼终端组的总数，确定终端的分组值n包括：
首先，确定预置的用于用来表示终端待寻呼终端组信息的信息量大小，待寻呼终端组信息可以为待寻呼终端组的分组值信息，算法公式如下：
Figure PCTCN2019124252-appb-000001
Figure PCTCN2019124252-appb-000002
Figure PCTCN2019124252-appb-000003
表示对log 2K向上取整，其中，K为待寻呼终端组的总数。
计算得到表示终端分组值的信息量大小后，确定终端的ID字段中用来表示终端带寻 呼终端组信息的字段，并确定用来表示终端待寻呼终端组信息的字段所指示的终端分组值n，例如事先规定用终端的ID字段的最后X比特的字段来表示终端的分组值，那么计算得到终端分组值的信息量大小为4bit后，可知最后4比特的字段来表示终端的分组值，那么终端分组值也就确定了。
在本实现方式中，提供了终端分组值n的另一种确定公式，增加了方案可实施性和灵活性。
基于第一方面及其第一方面的第一种至第五种可实现方式中任一，在第一方面的第六种可实现方式中，寻呼指示信息可以是一个比特串，比特串中的每一个比特都对应一个待寻呼终端组，那么根据寻呼指示信息以及分组值n，确定终端在目标DRX周期内是否被网络设备寻呼具体包括：
确定比特串中与第n个待寻呼终端组对应的比特，该比特可以指示第n个待寻呼终端组的终端被在目标DRX周期内被网络设备寻呼，或第n个待寻呼终端组的终端在目标DRX周期内没有被网络设备寻呼。例如可以用比特“1”指示第n个待寻呼终端组的终端在目标DRX周期内被网络设备寻呼了，用比特“0”指示第n个待寻呼终端组的终端在目标DRX周期内没有被网络设备寻呼，反之亦可。
在本实现方式中，对终端在目标DRX周期内是否被寻呼的判定方式进行了详细说明，增加了方案的可实施性。
基于第一方面及其第一方面的第一种至第五种可实现方式中任一，在第一方面的第七种可实现方式中，目标DRX周期为当前DRX周期之后的任意一个或多个DRX周期。例如目标DRX周期可以为当前DRX周期之后第一个DRX周期，也可以为当前DRX周期之后的第一个和第三个和第五个DRX周期，还可以为当前DRX周期之后的第三个至第六个DRX周期，更多可能情况此处不一一举例。
在本实现方式中，当目标DRX周期为多个DRX周期时，可以在多个DRX周期都不检测寻呼消息，减小了寻呼消息检测的功耗。
基于第一方面及其第一方面的第一种至第五种可实现方式中任一，在第一方面的第八种可实现方式中，从网络设备接收寻呼指示信息包括：
可以通过物理下行共享信道(physical down link shared channel，PDSCH)从网络设备接收寻呼指示信息。
在本实现方式中，由于现有接收寻呼指示信息都是从PDCCH接收，本申请提供了从PDSCH接收的方式，增加了方案实施的灵活性。
基于第一方面及其第一方面的第一种至第五种可实现方式中任一，在第一方面的第九种可实现方式中，当目标DRX周期可以为连接态的非连续接收CRDX周期，此时在目标DRX周期内不检测寻呼消息包括：
在CDRX周期内的持续时间(ondurationtimer)不检测寻呼消息，或在CDRX周期内的非激活时间(inactivitytimer)不检测寻呼消息，或在CDRX周期内的ondurationtimer和inactivitytimer都不检测寻呼消息。
ondurationtimer和inactivitytimer分别对应一个定时器。
在本实现方式中，对目标DRX周期为CDRX周期的情况进行了说明，增加了方案的 多样性。
采用本申请提供的技术方案，通过从网络设备接收寻呼指示信息，并确定终端的分组值n，最后根据该寻呼指示信息以及终端的分组值，确定终端在当前非连续接收DRX周期之后的目标DRX周期内是否被网络设备寻呼。可见，本申请可以根据寻呼指示信息以及终端分组值确定终端在目标DRX周期是否被寻呼，从而确定是否需要在目标DRX周期内醒来检测寻呼消息，避免了在不需要检测寻呼消息时还检测寻呼消息，减小了寻呼消息检测的功耗。
本申请第二方面提供了一种通信方法，包括：
获取终端分组值n，分组值n表示终端为待寻呼终端组集合中第n个待寻呼终端组内的终端，待寻呼终端组集合包括至少一个待寻呼终端组，n为大于或等于0的整数。
在本实现方式中，待寻呼终端组集合的由来与第一方面中对应描述类似，此处不再赘述。
根据终端的分组值n配置寻呼指示信息，以便用寻呼指示信息指示第n个待寻呼终端组内的终端被网络设备寻呼了，或没有被网络设备寻呼。
发送寻呼指示信息给终端，以便终端根据寻呼指示信息以及自身分组值N确定终端在目标DRX周期内是否被网络设备寻呼，确定的方式与第一方面类似，此处不再赘述。同时目标DRX周期为终端当前所在的DRX周期之后的DRX周期。
在本实现方式中，获取终端分组值后，根据分组值配置寻呼指示信息，并把寻呼指示信息发送给终端，以便根据寻呼指示信息确定终端在目标DRX周期内有没有被寻呼，如果终端在目标DRX周期内没有被网络设备寻呼，那么在目标DRX周期不需要检测网络设备下发的寻呼消息，减小了寻呼消息检测的功耗。
基于第二方面，在第二方面的第一种可实现方式中，目标DRX周期为当前DRX周期之后的任意一个或多个DRX周期，可能的情况以及效果与第一方面的第七种可实现方式类似，此处不再赘述。
基于第二方面或第二方面的第一种可实现方式，在第二方面的第二种可实现方式中，发送寻呼指示信息至终端，具体包括：
可以通过PDSCH发送寻呼指示信息至终端。

在LTE或NR系统中，终端需要监听寻呼消息，来检测网络设备是否有针对此UE的寻呼信息域，终端在某一DRX周期对寻呼消息进行检测之前，可以先接收寻呼指示信息，现有寻呼指示信息用于指示终端在该DRX周期内是否被网络设备寻呼了，如果没有 被网络设备寻呼则表示网络设备没有向该终端发送寻呼消息，则该终端在该DRX周期也不需要执行寻呼消息的检测了。但是在该DRX周期之后的其他DRX周期终端是否被寻呼是未知的，若终端在其他DRX周期内没有被寻呼时却进行寻呼消息检测，会加大寻呼消息检测的功耗。本申请将该DRX周期定义为当前DRX周期，将其他DRX周期定义为目标DRX周期，通过与当前DRX周期对应的该寻呼指示信息，来指示终端在当前DRX周期之后的目标DRX周期内有没有被寻呼，参照图3，本申请通信方法具体包括：
首选需要说明的是，本申请将接入网络设备的终端分成了多个组，每个组称之为待寻呼终端组，分成的多个组的集合称之为待寻呼终端组集合，每一个待寻呼终端组中包括至少一个终端，某一终端被寻呼了，代表该终端所在的待寻呼终端组的终端都被寻呼了，反之亦然。
在本实施例中的通信方法可以由终端执行，也可以由终端内的芯片执行，具体此处不作限定。下面以终端执行为例进行说明：
301、从网络设备接收寻呼指示信息。
终端接收网络设备配置的寻呼指示信息，因为网络设备发送给终端的寻呼指示信息往往被多个待寻呼终端组的终端都接收到了，有些待寻呼终端组的终端被寻呼了，有些待寻呼终端组的终端没有被寻呼，而一个寻呼指示信息指示可以同时指示多个待寻呼终端组的寻呼情况，例如一个寻呼指示信息指示同时指示待寻呼终端组A被寻呼了，且待寻呼终端组B没有被寻呼，因此网络设备配置寻呼指示信息时需要知道终端所在的分组值，才能用寻呼指示信息指示该分组值代表的那一组的终端有没有被寻呼。
在本实施中，分组值n用于指示终端为待寻呼终端组集合中第n个待寻呼终端组内的终端，n为大于或等于0的整数。
在本实施例中，网络设备配置寻呼指示信息可以包括：网络设备先确定分组值后根据分组值配置寻呼指示信息，或者由网络设备获取终端确定的分组值后根据分组值配置寻呼指示信息，具体此处不作限定。
终端可以通过物理下行控制信道(physical down link control channel，PDCCH)接收寻呼指示信息，此时该寻呼指示信息包含在下行控制信息(downlink control information，DCI)中。终端也可以通过PDSCH接收寻呼指示信息，具体此处不作限定。
当终端通过PDCCH接收寻呼指示信息时，寻呼指示信息包含在DCI中，那么寻呼指示信息的比特长度可以在DCI中配置。可选的寻呼指示信息的比特长度或者承载寻呼指示的DCI比特长度可以由网络设备配置，寻呼指示信息的比特长度或者承载寻呼指示的DCI比特长度可以在系统信息(system information，SI)、主信息块(main information block，MIB)、最小剩余系统信息(minimum remaining system information，RMSI)、系统信息块1(system information block1，SIB1)、系统信息块2SIB2、系统信息块3SIB3、无限资源控制(radio resource control，RRC)信令、媒体接入控制控制元素(media access control-control element，MAC-CE)或物理广播信道(physical broadcast channel，PBCH)中配置。
在本实施例中，所述DCI的字段可以包括短消息字段和第一预留字段，短消息字段又可以包括最小短消息字段和第二预留字段，最小短消息字段可以为2bit。
可选的，寻呼指示信息的比特长度在DCI中配置，即用DCI中的某些字段指示寻呼指示信息，具体包括：寻呼指示信息由DCI中的短消息字段和/或第一预留字段指示，其中，寻呼指示信息由短消息字段指示具体可以为寻呼指示信息由最小短消息字段和/或第二预留字段指示。例如最小短消息字段为2bit，第二预留字段可以为1至6中的任意一个数据比特，若寻呼指示信息由最小短消息字段和第二预留字段指示，则1至6比特分别对应加上最小短消息字段的2bit，得到的寻呼指示信息的比特长度为3至8比特中相应的数据比特。再例如短消息字段为3bit，DCI中第一预留字段为1至6中的任意一个数据比特，若寻呼指示信息由短消息字段和第一预留字段指示，则1至6比特分别对应加上短消息字段的3bit，得到的寻呼指示信息的比特长度为3至9比特中相应的数据比特。
在本实施例中，也可以用DCI中的其他字段指示寻呼指示信息，例如DCI中的带宽信息字段、频域资源指示信息字段、时域信息字段、时域资源指示信息字段、虚拟资源块到物理资源块的映射字段、调制编码策略字段以及传输块缩减因子(TB Scaling)字段中的至少一个。
当终端通过PDSCH信道接收寻呼指示信息时，寻呼指示信息的比特长度可以在系统信息、MIB、RMSI、SIB1、SIB2、SIB3、RRC信令、MAC-CE、PBCH或DCI中配置。
302、确定分组值n。
在本实施例中，可以由终端自己配置分组值n，也可以由网络设备配置终端分组值n，若由网络设备配置终端分组值n，那么终端需要通过计算得到该终端的分组值n，具体的计算方式将在后面的实施例中论述。
303、根据寻呼指示信息以及终端的分组值，确定终端在当前DRX周期之后的目标DRX周期内是否被网络设备寻呼。
终端根据自身分组值以及寻呼指示信息，确定终端在目标DRX周期内被网络设备寻呼的情况，即终端在目标DRX周期内被网络设备寻呼了或者终端没有被网络设备寻呼。其中，目标DRX周期为当前DRX周期之后的M个DRX周期，M为大于或等于0的整数，本申请的M值可以由基站配置，也可以由终端设备上报，基站配置M值的方式可以是基站在系统信息、MIB、RMSI、SIB1、SIB2、SIB3、RRC信令、MAC-CE、PBCH或DCI中配置。例如M等于1表示终端在当前DRX周期之后的第一个DRX周期不需要检测寻呼消息，M等于2表示终端在当前DRX周期之后的第二个DRX周期或第一个DRX周期和第二个DRX周期不需要检测寻呼消息，那么M等于0表示终端在当前DRX周期之后不存在目标DRX周期不需要检测寻呼消息，即终端在当前DRX周期之后的第一个DRX周期就需要检测寻呼指示消息，或终端在当前DRX周期之后的所有DRX周期都需要检测寻呼指示消息。M的值可以在0、1、2、3、4、5、6、7、8、9、10、11、12、13、14、15、16的全部值中取一个值，也可以在0、1、2、3、4、5、6、7、8、9、10、11、12、13、14、15、16部分值中取一个值。
本申请DRX周期(包括当前DRX周期和目标DRX周期)的长度可以由终端设备确定后上报给网络设备，也可以由网络设备配置，一种可能的情况是：终端上报了一个DRX周期，同时网络设备配置了一个DRX周期，基于终端的业务不同，如果终端上报的DRX周期大于网络设备配置的DRX周期，则以网络设备配置的DRX周期长度作为本申请 的当前DRX周期和目标DRX周期的长度，此时终端设备可以间隔至少一个DRX周期后再检测寻呼消息。
当终端确定在目标DRX周期内被网络设备寻呼时，终端在目标DRX周期检测寻呼消息。当终端确定在目标DRX周期没有被网络设备寻呼时，则终端在目标DRX周期不检测寻呼消息，以此减小了寻呼消息检测的功耗。例如终端可以根据寻呼指示信息确定该终端在当前DRX周期之后的接下来第一个DRX周期是否被网络设备寻呼，如图4(a)所示，当前DRX周期为DRX周期1，可见终端在当前DRX周期被寻呼了，且终端在当前DRX周期之后的第一个DRX周期即DRX周期2没有被网络设备寻呼，但是在之后的第三个DRX周期即DRX周期3被网络设备寻呼了，同时在第四个DRX周期即DRX周期4没有被网络设备寻呼，因此寻呼指示消息可以直接指示终端当前DRX周期之后的DRX周期2没有被寻呼，或者寻呼指示消息可以直接指示终端当前DRX周期之后的DRX周期2以及DRX周期4没有被寻呼。再例如寻呼指示信息指示终端在当前DRX周期之后的接下来连续Z个DRX周期被网络设备寻呼了或者没有被网络设备寻呼，Z为正整数，如图4(b)所示，当前DRX周期为DRX周期1，终端在当前DRX周期之后的连续两个DRX周期被网络设备寻呼了，则寻呼指示信息可以指示终端在DRX周期2至DRX周期3内被网络设备寻呼，则终端需要检测寻呼消息。或终端还可以根据寻呼指示信息确定该终端在当前DRX周期之后再间断连续一个或多个DRX周期后的一个或多个DRX周期是否被网络设备寻呼，更多举例此处不一一列举。
本申请的DRX周期(包括当前DRX周期和目标DRX周期)可以为空闲态的DRX周期，也可以为连接态的DRX周期即CDRX周期。当DRX周期为空闲态的DRX周期时，寻呼指示信息可以指示终端在处于空闲态的目标DRX周期内是否检测寻呼消息。当DRX周期为连接态的DRX周期时，寻呼指示信息可以指示终端在当前CDRX周期之后的目标CDRX周期的持续时间(ondurationtimer)和/或非激活时间(inactivitytimer)是否需要检测数据信息。如图4(c)所示，寻呼指示消息可以指示终端在DRX周期1之后的连续两个CDRX周期(CDRX周期2和CDRX周期3)的ondurationtimer和inactivitytimer内不需要检测数据信息。
在本实施例中，ondurationtimer为终端监控下行PDCCH数据的时间，这段时间内终端处于唤醒(wake up)状态。inactivitytimer表示终端在ondurationtimer内接收到下行PDCCH数据之后要延长监听下行PDCCH数据的时间，即在inactivitytimer内，即便原本配置的ondurationtimer已经结束，终端仍然需要继续监听下行PDCCH数据，直到inactivitytimer超时。ondurationtimer和inactivitytimer分别对应一个定时器。
在本实施例中，终端在某一目标CDRX周期内的ondurationtimer和/或inactivitytimer是否需要检测数据信息，有多种可能的情况，下面对其中一种可能的情况进行说明：
终端在ondurationtimer和/或inactivitytimer持续T个时隙或T个符号或T个子帧或Tms(毫秒)不需要检测数据信息，该数据信息可以为PDCCH数据和/或PDSCH数据，例如可以是寻呼消息的PDCCH数据或寻呼消息的PDSCH数据。T的值可以根据ondurationtimer和/或inactivitytimer配置。例如inactivitytimer为10ms，则T的值可以为0至10ms中任一值，当T等于0ms时，表示终端在inactivitytimer内都需要检测数据信息或 终端在ondurationtimer和inactivitytimer内都需要检测数据信息，T为2时表示终端在inactivitytimer中持续2ms不需要检测数据信息。
可选的，T的值从0、1、2、3、4、5、6、7、8、9、10、11、12、13、14、15以及16的部分或者全部的值中选择一个值，例如从0至8中选择一个值。T的值也可以为分数，例如从1/2、1/4、3/4、1/3、2/3、1/8、3/8、5/8和7/8中的部分或全部的值中选择一个值，T为1/2的时候，表示下一个CDRX周期的ondurationtimer中持续1/2时间段不用检测数据、或在下一个C-DRX周期的ondurationtimer内持续1/2个时隙不用检测数据或在下一个CDRX周期的ondurationtimer内持续1/2个子帧不用检测数据。当终端不需要检测数据时，网络设备可以指示ondurationtimer不用进行计时，即结束ondurationtimer的计时，进入下一个DRX周期，网络设备可以使用1比特数据指示是否需要结束计时，0表示结束计时，1表示不结束计时，反之亦然。
在本实施例中，T的值还可以由RRC信令、MAC-CE信令、系统信息或DCI中配置的。T的个数可以是从1至10239的全部值或部分值中选择的整数值，例如RRC信令配置M个T值，然后通过MAC-CE信令激活其中一个或多个T值。还可以通过RRC信令配置M个T值，通过DCI信令进行激活其中一个或多个T值。还可以通过MAC-CE信令配置M个T值，通过DCI信令激活其中一个或多个T值。还可以是通过RRC信令配置M个T值，通过MAC-CE再从M个T值中选择M1个T值，最后通过DCI信令激活一个或多个T值，更多举例此处不一一列举。
在本实施例中，终端可以根据寻呼指示信息以及终端的分组值确定终端在目标DRX周期是否被寻呼，如果没有被寻呼了，终端在目标DRX周期不用醒来检测寻呼消息，避免了终端在不需要检测寻呼消息时还检测寻呼消息，减小了寻呼消息检测的功耗。
基于图3所示的通信方法，确定终端在目标DRX周期内是否被网络设备寻呼之前，若分组值是由网络设备配置的，终端还需要根据寻呼指示消息确定终端的分组值，下面参照图5，对其中的两种可能的确定方式进行说明：
501、网络设备获取终端的分组值；
终端的分组值可以由网络设备分配，也可以由终端配置后发送网络设备，具体此处不作限定。
502、终端从网络设备获取寻呼指示信息；
本实施例步骤502与上述实施例步骤301类似，具体此处不再赘述。
503、终端根据寻呼指示信息确定终端的分组值n；
终端可以根据寻呼指示信息确定分组值n。一种可能的情况为：通过寻呼指示信息中的预置的第一字段指示分组值，例如寻呼指示信息的第一字段为1001，则指示终端位于第9组。
另一种可能的情况为：根据当前DRX周期内的寻呼时机的数目、终端的身份标识以及分组总数中的至少一个，确定终端的分组值。分组总数指的是待寻呼终端组的总数。
其中，分组总数由寻呼消息指示信息确定，一种可能的情况是可以通过寻呼指示信息的信息量大小确定，例如寻呼指示信息为16bit，则表示有16组待寻呼终端组，即分组总 数的值为16。还有一种可能的情况是通过寻呼指示信息指示分组总数，例如通过寻呼指示信息的第二字段1110指示分组总数的值为13，表示有13组待寻呼终端组。终端的身份标识ID可以为终端的国际移动用户识别号(international mobile subscriber identity，IMSI)。
根据当前DRX周期内寻呼时机PO的数目、终端的身份标识ID以及分组总数中的至少一个，确定终端的分组值有多种可实现的方式，下面举例说明几种可实现方式：
a、根据当前DRX周期内寻呼时机PO的数目、终端的身份标识ID以及分组总数确定终端的分组值。
确定终端的分组值按照如下算法确定：
终端的分组值n＝(A/N)mod K，n为大于或等于0的整数，当n等于0时，表示从第0组开始计算分组；
其中，A为终端ID的全部或部分字段的信息量，例如当终端ID的信息量为64bit时，A可以为全部字段的信息量64bit，也可以为截断得到的部分字段的信息量16bit，当A为终端ID的部分字段的信息量时，截断得到的部分字段可以由终端配置后上报给网络设备，也可以由核心网配置，配置截断得到的部分字段的设备具体此处不作限定。N可以为当前DRX周期内PO的数目，寻呼时机PO的数目可以为寻呼帧的数目，即当前DRX周期内PO的数目可以与当前DRX周期内寻呼帧的数目相同，寻呼时机PO的数目还可以为寻呼帧内PO的数目，N的值也可以为事先预置的常数，N的值具体此处不作限定。所述K表示分组总数。
需要说明的是，所述A/N的结果值为进行取整数处理后的结果值，可以向上取整，也向下取整。
例如，终端ID中部分字段信息量A为16bit，当前DRX周期内PO的数目N为4，分组总数K为16组，计算得到终端所在组n为第4组。
b、根据终端的身份标识ID以及分组总数确定终端的分组值。
确定终端的分组值按照如下算法确定：
终端的分组值n＝Amod K，n为大于等于0的整数，当n等于0时，表示从第0组开始计算分组；
其中，A与K的定义以及取值情况与上述方式a类似，具体此处不再赘述。
c、根据分组总数确定终端的分组值。
在本实施例中，分组值可以携带在寻呼指示信息中。
首先，可以采用下面的公式得到用来表示待寻呼终端组信息的信息量，这里的待寻呼组信息可以为待寻呼终端组的分组值信息，那么：
Figure PCTCN2019124252-appb-000004
Figure PCTCN2019124252-appb-000005
表示对log 2K向上取整，K为分组总数。例如分组总数为16，则用来表示终端分组值的信息量为4bit。
随后，由于网络设备事先定义了寻呼指示信息的第三字段用于指示终端分组，对于终端而言，得到分组值的信息量大小后，根据该信息量大小找到寻呼指示信息中的所述第三字段，再确定该第三字段所指示的具体分组值。例如寻呼指示信息的比特串为1100101001101001，其中网络设备规定最后X bit用于表示终端分组，对于终端而言，终端根据寻呼指示信息计算得到终端分组值信息量X bit为4bit后，确定该4bit信息量所对应的 字段为1001，可见该终端位于第九组。
d、根据终端的身份标识ID以及分组总数，得到所述终端的分组值。
在本实施例中，分组值可以携带在终端的身份标识中。
首先，可以采用下面的公式得到用来表示待寻呼终端组信息的信息量，这里的待寻呼组信息可以为待寻呼终端组的分组值信息，那么：
Figure PCTCN2019124252-appb-000006
其中，K为分组总数，不做赘述。
随后，由于事先定义了终端的身份标识的第四字段用于指示终端分组，对于终端而言，若终端并不知道第四字段具体为身份标识中的哪一部分字段，终端需要计算得到终端分组值信息量后，确定该终端分组值信息量所对应的终端ID中的所述第四字段，再确定该第四字段所指示的具体分组值。例如终端身份标识ID字段的比特串为1100101001101001，其中规定最后X bit用于表示终端分组值，终端根据寻呼指示信息计算得到终端分组值的信息量X bit为4bit后，确定该4bit信息量所对应的字段为1001，可见该终端位于第九组。
可以用全部的终端身份标识字段来计算终端的分组，也可以用截断得到的部分字段计算终端的分组，若用截断得到的部分字段来指示终端的分组，则指示终端分组值的第四字段只能从截断得到的部分字段中选择，截断的部分字段可以由终端配置后上报给核心网或网络设备，也可以由核心网配置，配置截断得到的部分字段的设备具体此处不作限定。
在本实施例中，第一字段、第二字段以及第三字段均为寻呼指示信息中任意字段，第四字段为终端身份标识的任意字段，第一字段、第二字段、第三字段以及第四字段的字段长度本申请均不作限定。
504、终端根据寻呼指示信息以及终端的分组值，确定终端在当前DRX周期之后的目标DRX周期内是否被网络设备寻呼。
本实施例步骤与上述实施例步骤303类似，需要说明的是：
终端确定分组值后，根据该分组值以及寻呼指示信息确定终端在目标DRX周期内是否被网络设备寻呼，一种可实现的方式是：寻呼指示信息是一个比特串，比特串中的每一位比特对应一个终端的分组，例如寻呼指示信息为001001100100，第2、5、6和9bit为1，表示第2、5、6和9组的终端被呼叫，那么第2、5、6和9组的终端就要接收寻呼消息，第1、3、4、7、8、10、11以及12组的终端没有被呼叫，那么第1、3、4、7、8、10、11以及12组的终端不需要接收寻呼消息。反之也可以用1表示终端没有被寻呼了，用0表示终端被寻呼，不做赘述。
上面从终端的角度对本申请的通信方法进行了叙述，请参照图6，下面将从另一角度对本申请的通信方法进行说明。
在本实施例中的通信方法可以由网络设备执行，也可以由网络设备内的芯片执行，具体此处不作限定。下面以网络设备执行为例进行说明：
601、获取终端的分组信息。
本实施例步骤与上述实施例步骤501类似，具体此处不再赘述。
602、发送寻呼指示信息至终端。
网络设备根据终端分组值配置寻呼指示信息并发送寻呼指示信息给终端，终端接收后根据该寻呼指示信息以及终端的分组信息确定终端在当前DRX周期之后的目标DRX周期内是否被网络设备寻呼。
网络设备发送寻呼指示信息的方式可以通过PDCCH信道发送，也可以通过PDSCH信道发送，通过不同的信道发送时，寻呼指示信息的配置方式可以是相同的，也可以是不同的，具体与上述图3和图5类似，此处不再赘述。
在本实施例中，终端确定是否被网络设备寻呼的方式、当前DRX周期以及目标DRX周期的定义与上述图3和图5对应描述类似，具体此处不再赘述。
在本实施例中，网络设备获取终端分组值后，根据终端分组值配置寻呼指示信息并发送寻呼指示信息给终端，以便终端根据寻呼指示信息以及分组值确定自身在目标DRX周期内是否被寻呼了，避免了终端在不需要检测寻呼消息时还检测寻呼消息，减小了寻呼消息检测的功耗。
