图1是本申请实施例提供的一种通信系统的示意图。
如图1所示的通信网络中，UE110通过中继设备120接入接入网设备130，其中，UE110与中继设备120之间有通信接口，中继设备120与接入网设备130之间有通信接口。其中，UE110是远端(remote)UE，中继设备120既可以是中继终端，也可以是中继站等中继网络节点。可以理解，一个中继设备可以服务于一个或多个remote UE。其中，remote UE为接入中继设备的UE，可以直接通过中继设备进行业务传输，或者通过中继设备接入接入网设备进行业务传输。图1中示出的UE110仅为一种示例，不构成对本申请实施例的任何限定。
在UE110通过中继设备120接入接入网设备130后，接入网设备130可以对UE110发起寻呼(paging)过程，UE110接收相应的寻呼消息。
一般地，在引入中继设备的通信场景中，接入网设备对remote UE的寻呼(paging)可以有如下三种方式：
1)中继设备在该中继设备服务的一个或多个remote UE的寻呼时机(paging occasion，PO)分别接收接入网设备发送的寻呼消息，即接入网设备对该中继设备下的每个remote  UE的寻呼消息分别在每个remote UE的寻呼时机上发送，然后中继设备转发寻呼消息给相应的remote UE；
2)中继设备在该中继设备的寻呼时机上接收接入网设备发送的寻呼消息，即接入网设备对该中继设备下的每个remote UE的寻呼消息都在该中继设备的寻呼时机上发送，然后中继设备转发寻呼消息给相应的remote UE；
3)接入网设备在中继设备的寻呼时机、以及在接入网设备服务的一个或多个remote UE的寻呼时机上均发送寻呼消息，中继设备和remote UE分别在各自的寻呼时机监听接入网设备的寻呼，从而中继设备在自己的寻呼时机上接收接入网设备对该中继设备的寻呼，remote UE在自己的寻呼时机上接收接入网设备对该remote UE的寻呼。
可以理解，在方式1)中，中继设备在每个remote UE的寻呼时机上监听接入网设备对remote UE的寻呼；在方式2)中，中继设备在自己的寻呼时机上监听接入网设备对remote UE的寻呼；在方式3)中，由于remote UE自己监听寻呼，则remote UE可以接收到接入网设备向其发送的寻呼消息，则中继设备无需再向remote UE转发寻呼消息。如上三种寻呼方式的信令开销不同，各个设备的功耗也不同。此外，如果remote UE所处位置的信号质量较差，采用方式3)可能导致remote UE无法正确接收寻呼。可以理解地，中继设备监听接入网设备对remote UE的寻呼的方式不限于本申请中的寻呼方式1)或2)，且上述三种寻呼方式仅为示例性方案，不构成对本申请实施例的任何限定。
如图1所示，接入网设备具有覆盖区域，覆盖区域具体可以是指该接入网设备发射的信号所能辐射到的空间范围，覆盖区域也可以称为信号覆盖范围或者信号覆盖区域。可以理解，接入网设备的覆盖区域中有信号覆盖较好的区域以及信号覆盖较差的区域，例如，靠近接入网设备的区域的信号质量较好，而在覆盖区域边缘的信号质量较差。为了支持更大的覆盖深度和容量性能，可以采用覆盖增强(coverage enhancement，CE)技术，将接入网设备的覆盖区域划分为不同的覆盖增强等级(CE等级，CE level)。
在采用CE机制的情况下，可以包括采用多个等级，不同的CE等级用于表示载波在小区中的不同的位置的覆盖情况或覆盖能力，其中载波的覆盖情况可以通过信号质量表征。作为示例而非限定，CE机制可以包括CE等级0-3。其中，CE等级0至CE等级3依次对应的信号质量由高到低。例如，CE等级0对应信号质量最好的情况，CE等级3对应信号质量最差的情况。应理解，CE等级与信号质量也可以采用其他关联关系对应，例如，CE等级0-3依次对应的信号质量可以由低至高。本申请实施例中以CE等级0-3依次对应的信号质量由高至低为例进行说明。另外，也可以使用更多或更少的CE等级表示信号的覆盖能力。本申请不作限定。为了方便说明，本申请实施例中将UE当前位置的CE等级称为该UE的CE等级。
上述不同的CE等级可以对应不同的数据传输重复次数和/或调制方式，以达到覆盖与容量的平衡。上述重复次数，可以指在连续子帧的相同资源块中调度相同的数据的次数。接收端可以通过混合自动重传请求(hybrid automatic repeat request,HARQ)对接收的数据进行合并获得合并增益，以提高边缘覆盖性能。其中，上述数据传输重复次数可以指传输数据的最大重复次数，包括业务最大重复发送次数。其中，所述业务重复发送是指即在连续时间单元的相同资源块中调度相同的数据。从而，在接收端可以通过HARQ合并 获得合并增益，减少重传次数，提升边缘覆盖性能。其中，所述时间单元可以是时隙(slot)，迷你时隙(mini slot)，子帧(sub-frame)或其它时域上的一种资源单位。可以理解，业务重复发送可以是指UE向网络侧重复发送业务相关的数据，也可以是指网络侧向UE重复发送业务相关的数据。业务重复发送适用于寻呼过程或系统消息发送等多种通信过程，例如，在寻呼过程中，接入网设备可以根据UE的信号质量等级对应的业务最大重复发送次数来重复发送寻呼消息。
本申请实施例通过在接入网设备对remote UE的寻呼过程中引入基于信号质量的判断，例如结合上述CE等级，为remote UE选取合适的寻呼方式，减少remote UE以及中继设备的功耗，节约系统的信令开销，提升通信质量。
可以理解，在本申请实施例中，UE通过第一设备接入接入网设备，因此，如下实施例中出现的UE为remote UE，具体地，所述UE为接入或驻留在第一设备下的remote UE，或者为第一设备服务的remote UE；第一设备为中继设备，例如中继点或者中继终端；接入网设备可以是基站等接入网设备，以下实施例中不再做说明。
本申请中所示的通信方法中的步骤或操作仅是示例，其中，部分步骤可以不执行，或者，其中一些步骤可以由其它操作或步骤代替。此外，各个步骤可以按照本申请实施例呈现的不同的顺序来执行。此外，为了便于说明，以UE、第一设备(中继设备)、以及接入网设备作为执行主体为例，对本申请实施例所示的通信方法予以说明，可以理解，本申请实施例所述的通信方法的执行主体也可以是其他通信装置，例如芯片，下文将不再做说明。
图2是本申请实施例提供的一种通信方法的流程示意图。该方法可以适用于图1所示的通信系统中。
在本申请实施例中，接入网设备可以对UE和/或第一设备进行寻呼，UE可以确定是否对接入网设备的寻呼进行监听。
该方法包括：
S201：UE确定第一信号质量，所述第一信号质量对应于接入网设备。
其中，所述第一信号质量对应于接入网设备是指：所述第一信号质量是所述接入网设备下的小区的信号质量。例如，第一信号质量可以是UE的服务小区的信号质量，该服务小区属于所述上述接入网设备，即所述第一信号质量可以用UE的服务小区的信号质量表征。UE可以对其服务小区进行信号质量测量，从而得到所述第一信号质量。所述服务小区的信号质量可以用参考信号接收功率(reference signal received power，RSRP)、参考信号接收质量(reference signal received quality，RSRQ)、信号干扰噪声比(signal to interference plus noise ratio，SINR)等任意一种或多种参数表征。本申请实施例对于UE测量服务小区的信号质量的方式不做限定。
S202：UE发送第一消息，所述第一消息用于指示所述UE对所述接入网设备的寻呼的监听状态。
其中，所述第一消息是根据所述第一信号质量确定的。例如，UE可以根据所述第一 信号质量确定是否监听接入网设备对该UE的寻呼，从而确定所述第一消息的具体内容。
本申请实施例中所述的接入网设备的寻呼包括接入网设备对包括该UE在内的接入该接入网设备的一个或多个UE的寻呼，例如，所述一个或多个UE既可以包括通过中继设备接入该接入网设备的remote UE，也可以包括直接接入该接入网设备的普通UE，不做限定。接入网设备对UE的寻呼包括接入网设备在UE的寻呼时机发送的寻呼，本申请中不限定该寻呼对应的寻呼消息是否包含UE的标识；或者接入网设备对UE的寻呼包括接入网设备在中继设备的寻呼时机上发送的寻呼，该寻呼对应的寻呼消息中包含UE的标识。此外，接入网设备还可以发起针对中继设备(例如，上述第一设备)的寻呼，因此所述接入网设备的寻呼还可以包括接入网设备对中继设备的寻呼。
本申请实施例中所述的监听状态可以包括UE直接监听或者不直接监听所述接入网设备对该UE的寻呼。其中，所述直接监听是指UE在自己的寻呼时机上监听接入网设备发送的寻呼，从而UE可以直接接收到接入网设备发送的寻呼消息。相对地，若UE不直接监听所述寻呼，则UE可以对所述寻呼进行间接监听，所述间接监听可以包括UE监听第一设备转发的接入网设备对UE的寻呼，从而UE可以从第一设备接收到接入网设备发送的寻呼消息。对于接入网设备对第一设备的寻呼，UE可以不监听。
例如，UE监听接入网设备的寻呼可以理解为UE在该UE的寻呼时机上直接监听接入网设备针对UE发送的寻呼，在UE直接监听接入网设备针对UE发送的寻呼的情况下，该第一设备可以不监听接入网设备对UE的寻呼，但是监听接入网设备对第一设备的寻呼。
此外，在UE不直接监听接入网设备的寻呼的情况下，UE会监听第一设备转发的接入网设备对UE的寻呼。可以理解地，第一设备转发的接入网设备对UE的寻呼可以是第一设备通过前文所述寻呼方式1)或寻呼方式2)接收到的。其中，寻呼方式1)或寻呼方式2)仅为一种示例，本申请对第一设备转发接入网设备对UE的寻呼的方式不做限定。在UE不直接监听接入网设备的寻呼，也可以称为UE间接监听接入网设备对UE的寻呼。
在本申请实施例中，接入网设备向UE发送寻呼也可以称为接入网设备向UE发送寻呼消息，相应地，接收寻呼也可以称为接收寻呼消息，以下不再做说明。
S203：第一设备获取所述第一消息。
可以理解，第一设备可以从其服务的至少一个UE分别接收至少一个所述第一消息。
可选地，在本申请的一个实施方式中，UE向第一设备发送所述第一消息。相应地，第一设备从该UE接收所述第一消息。进而，第一设备可以向接入网设备发送用于指示UE标识和UE对应的对所述接入网设备的寻呼的监听状态的指示消息。该指示消息可以是从UE接收的所述第一消息，例如通过透传方式发送所述第一消息；或者该指示消息也可以仅包括从UE接收的所述第一消息中的部分内容。
可选地，在本申请的一个实施方式中，UE向接入网设备发送所述第一消息。相应地，接入网设备接收所述第一消息。进而，接入网设备可以向第一设备发送用于指示UE标识和UE对应的对所述接入网设备的寻呼的监听状态的指示消息。该指示消息可以是从 UE接收的所述第一消息，例如通过透传方式发送所述第一消息；或者该指示消息也可以仅包括从UE接收的所述第一消息中的部分内容。
可选地，在本申请的一个实施方式中，UE分别向接入网设备以及第一设备发送所述第一消息。相应地，第一设备从该UE接收所述第一消息。
其中，所述第一消息可以是UE向第一设备或接入网设备发送的任一消息，例如是请求消息或者指示消息，本申请实施例对此不做特别限定。
S204：第一设备根据所述第一消息确定对所述接入网设备的寻呼的监听状态。
具体地，第一设备根据获取到的第一消息确定是否监听(或称为“协助监听”)接入网设备对UE的寻呼，包括：当所述第一消息用于指示UE不直接监听接入网设备对UE的寻呼，所述第一设备确定监听接入网设备对UE的寻呼。作为一种实现方式，第一设备可以通过前文所述寻呼方式1)或2)监听接入网设备对UE的寻呼。或者，当所述第一消息用于指示UE直接监听接入网设备对UE的寻呼，所述第一设备确定不监听接入网设备对UE的寻呼，则可以用寻呼方式3)由UE对所述寻呼进行监听。
可选地，在本申请的一个实施方式中，所述第一设备确定所述第一设备对所述寻呼的监听状态后，向接入网设备发送第二消息，其中，所述第二消息用于指示所述UE对所述寻呼的监听状态，或者，所述第二消息用于指示所述第一设备对所述寻呼的监听状态。
可选地，在本申请的一个实施方式中，当接入网设备从UE或第一设备接收所述第一消息、或者从所述第一设备接收所述第二消息之后，所述方法还包括：接入网设备改变所述寻呼的寻呼时机。例如，接入网设备可以根据所述第一消息和当前寻呼方式确定是否改变对该UE寻呼的时机。
若所述第一消息用于指示由UE直接监听所述接入网设备对UE的寻呼，且当前采用寻呼方式2)，即接入网设备在第一设备的寻呼时机上发送所述寻呼，并由第一设备对所述寻呼进行监听，接入网设备通过所述第一消息获知寻呼方式改变为由UE对所述寻呼进行直接监听后，可以确定在包括所述UE的寻呼时机在内的接入该接入网设备的一个或多个UE的寻呼时机上发送所述寻呼，即接入网设备采用寻呼方式3)来寻呼UE。
若所述第一消息用于指示UE不直接监听所述接入网设备对UE的寻呼，且当前采用寻呼方式3)，即接入网设备在UE的寻呼时机上发送所述寻呼，并由UE对所述寻呼进行直接监听，接入网设备通过所述第一消息获知寻呼方式改变为由第一设备对所述寻呼进行监听后，可以确定在所述第一设备的寻呼时机上发送所述寻呼，即接入网设备采用寻呼方式2)来寻呼UE。
可以理解，若当前接入网设备采用寻呼方式1)或寻呼方式3)对UE进行寻呼，由于所述寻呼均在UE的寻呼时机上发送，无论所述第一消息指示的UE对所述寻呼的监听状态如何，接入网设备可以不改变所述寻呼的寻呼时机。在另一个实施方式中，若当前采用寻呼方式1)或寻呼方式3)，由于所述寻呼时机不改变，则接入网设备可以不用获取所述第一消息，即UE或者第一设备可以不向接入网设备发送所述第一消息。
可选地，在本申请的一个实施方式中，所述第一消息中包含第一信息，所述第一信 息用于指示UE对所述寻呼的监听状态。所述第一信息可以是第一消息中的指示位。例如，所述第一信息可以占用所述第一消息中的一个或多个比特位，以所述比特位上的二进制码表示UE对接入网设备的寻呼的监听状态。
可选地，所述第一信息可以用于指示UE是否监听接入网设备的寻呼。可选地，第一消息中的一个或多个比特位是变化的值，不同的值代表不同的监听状态。例如，第一信息占用一个比特位，则当该比特位为“1”时，表示UE直接监听接入网设备的寻呼；当该比特位为“0”时，表示UE不直接监听所述寻呼。本申请实施例中，对于比特位具体取值方式不做限定。
可选地，UE可以只在UE确定直接监听接入网设备的寻呼时，发送包含第一信息的第一消息，也就是说，所述第一信息用于指示UE直接监听所述寻呼。具体地，第一消息中的一个或多个比特位为固定的值，该值表示UE直接监听所述寻呼。例如，第一信息占用一个比特位，该比特位为“1”或“0”表示UE直接监听所述寻呼。可以理解的是，在UE确定不直接监听接入网设备的寻呼时，可以不发送所述第一消息，那么第一设备没有获取到所述第一消息，例如经过预设的接收时间未收到所述第一消息，则对接入网设备对UE的寻呼进行协助监听。
可选地，UE可以只在UE确定不直接监听接入网设备的寻呼时，发送包含第一信息的第一消息，也就是说，所述第一信息用于指示UE不直接监听所述寻呼，则第一消息中的相应比特位的值表示UE不直接监听所述寻呼。例如，第一信息占用一个比特位，该比特位为“1”或“0”表示UE不直接监听所述寻呼。相应地，在UE确定直接监听接入网设备的寻呼时，可以不发送所述第一消息，那么第一设备没有获取到所述第一消息，例如经过预设的接收时间未收到所述第一消息，则不对接入网设备对UE的寻呼进行协助监听。
可选地，指示UE不直接监听所述寻呼的比特位与指示UE直接监听所述寻呼的比特位的位置不相同，且取值可以相同也可以不相同。当指示UE直接监听所述寻呼的比特位上有值时，指示UE不直接监听所述寻呼的比特位为空或缺省值，反之亦然。
可选地，指示UE不直接监听所述寻呼的比特位与指示UE直接监听所述寻呼的比特位的位置相同且取值相同。例如，第一信息占用一个比特位，该比特位的值为“1”或“0”，当UE只在确定直接监听接入网设备的寻呼时才发送包含所述第一消息的情况下，该比特位指示UE直接监听所述寻呼；当UE只在确定不直接监听接入网设备的寻呼时才发送包含所述第一消息的情况下，该比特位指示UE不直接监听所述寻呼。
本申请实施例对上述第一信息的形式不做限定，例如第一信息还可以是布尔值(例如，“False”表示不监听寻呼，“True”表示监听寻呼)。
上述第一信息的含义可以预先设置在UE与接收端(第一设备/接入网设备)中。
可选地，在本申请的一个实施方式中，第一消息也可以直接指示UE对接入网设备的寻呼的监听状态。具体地，所述第一消息可以包含值为空的一个或多个比特位，该一个或多个比特位的位置固定，所述值为空的一个或多个比特位用于指示UE直接监听或者不直接监听接入网设备的寻呼。
可选地，指示UE直接监听所述寻呼的值为空的比特位与指示UE不直接监听所述寻呼的值为空比特位的位置可以不同。例如，所述第一消息中包含{比特位1，比特位2，…比特位n}，当比特位1的值为“NULL(空)”，则第一消息指示UE直接监听所述寻呼，当比特位2的值为“NULL(空)”，则第一消息指示UE不直接监听所述寻呼。
可选地，所述第一消息中指示UE直接监听所述寻呼的值为空的比特位与指示UE不直接监听所述寻呼的值为空的比特位的位置可以相同，例如，所述第一消息中的比特位1的值为“NULL(空)”，若UE确定只在直接监听接入网设备的寻呼时发送所述第一消息，则比特位1指示UE直接监听所述寻呼；若UE确定只在不直接监听接入网设备的寻呼时发送所述第一消息，则比特位1指示UE不直接监听所述寻呼。当接收方(第一设备/接入网设备)获取所述第一消息后，通过读取所述值为空的一个或多个比特位，就能够获知UE对接入网设备的寻呼的监听状态。
可选地，在本申请的一个实施方式中，如果第一消息中指示UE不直接监听所述寻呼的比特位以及第一消息中指示UE监听所述寻呼的比特位均为空或缺省值，则第一设备收到该第一消息后，可以保持监听或不监听所述寻呼的状态，即不用改变当前的寻呼方式。
一种可能的方式中，上述这些固定位置的值为空的比特位的含义可以是预先设定在UE或第一设备或网络设备中的。
可以理解，前述第一设备向接入网设备发送的第二消息的具体内容可以参照上述第一消息的描述，不做赘述。
可选地，在本申请的一个实施方式中，作为S202的替代步骤，UE可以向第一设备或者接入网设备发送序列或者参考信号等第二信息，所述第二信息用于指示UE对所述寻呼的监听状态。例如，可以用参考信号的电平值表示所述监听状态，例如高电平值表示UE直接监听所述寻呼；低电平值表示UE不直接监听所述寻呼。又例如，用序列中的不同二进制码表示所述监听状态，例如序列“00”表示UE直接监听所述寻呼；序列“01”表示UE不直接监听所述寻呼，序列的具体表示方式与上述第一消息中的第一信息类似，不做赘述。采用参考信号或者序列等信息，信息量小，可以节约传输资源。
可选地，在本申请的一个实施方式中，所示第一消息用于指示UE对第一设备转发的寻呼的监听状态。所述第一设备转发的寻呼是指第一设备监听到接入网设备对UE的寻呼，进而转发给UE的寻呼消息。当UE监听所述第一设备转发的寻呼时，即UE不直接监听接入网设备对UE的寻呼，则第一设备需要监听接入网设备对UE的寻呼，并转发所述寻呼给UE；当UE不直接监听所述第一设备转发的寻呼时，即UE直接监听接入网设备对UE的寻呼，则第一设备不监听接入网设备对UE的寻呼。
可选地，当第一消息是指示消息，即UE指示第一设备该UE监听或者不监听接入网设备的寻呼，第一设备根据第一消息来调整对接入网设备对UE的寻呼的监听状态。例如，当UE确定不监听接入网设备对UE的寻呼，则可以向第一设备发送该指示消息，指示UE不直接监听接入网设备对UE的寻呼，或者指示第一设备监听接入网设备对UE的寻呼；当UE确定由其监听所述寻呼，则可以向第一设备发送指示消息，指示由UE直接监听接入网设备对UE的寻呼，或者指示第一设备不监听接入网设备对UE的寻呼。
可选地，当第一消息是请求消息，所述请求消息可以用于请求第一设备不监听或监听接入网设备对UE的寻呼，第一设备发送响应消息，用于向UE反馈是否接受请求。例如，第一设备可以根据自身的运行情况，确定是否接受UE的请求。一种可能的方式中，第一设备自身的运行情况，例如可以包括第一设备对来自接入网设备针对第一设备所服务的全部或者部分UE的寻呼的监听状态的统计情况。在另一种可能的方式中，第一设备根据自身的运行情况，并考虑第一设备当前的负载和/或耗电量等，若负载或耗电量高，且第一设备已对其他一个或多个UE的寻呼进行协助监听，则第一设备也可以决定不对最新发送请求消息的UE的寻呼进行协助监听，以免影响通信质量。
可选地，在本申请的一个实施方式中，第一设备可以基于该第一设备服务的一个或多个UE向其发送的请求消息，结合第一设备的监听模式(即寻呼方式)，确定是否协助监听UE的寻呼。例如，监听模式为第一设备的在第一设备自己的寻呼时机上监听全部UE的寻呼(即本申请中定义的寻呼方式2)，且第一设备下的所有UE都请求第一设备协助监听所述寻呼，则第一设备向每个UE回复响应消息指示该第一设备协助监听，也就是说接受所有UE的协助监听请求；又例如，监听模式为第一设备在每个UE的寻呼时机上分别监听寻呼(即本申请中定义的寻呼方式1)，第一设备可以在收到相应的UE发送的请求第一设备协助监听所述寻呼的请求消息后，向该UE回复响应消息，通知UE该第一设备协助监听，也就是说，接受该UE的协助监听请求。
作为一种实施方式，假设第一设备采用寻呼方式2)，即第一设备在其寻呼时机上监听接入网设备对UE的寻呼的场景下：
当第一设备接收到指示消息(第一消息的一种示例)，该指示消息指示UE不直接监听接入网设备对UE的寻呼，或者指示第一设备监听接入网设备对UE寻呼时，第一设备继续监听接入网设备对UE的寻呼；当第一设备接收到指示消息，指示消息指示UE监听接入网设备对UE的寻呼，或者指示消息指示第一设备停止监听接入网设备对UE寻呼时，第一设备停止监听接入网设备对UE的寻呼。可选地，UE开始监听接入网设备对UE的寻呼。可选地，UE可以在发送指示消息后等待一定时间或者收到第一设备的响应消息后开始监听接入网设备对UE的寻呼。或者，当第一设备接收到请求消息(第一消息的另一种示例)，请求消息指示UE监听接入网设备对UE的寻呼，或者请求消息指示第一设备停止监听接入网设备对UE寻呼时，第一设备发送响应消息，该响应消息用于指示该第一设备接受UE的请求，停止监听接入网设备对UE的寻呼。比如，第一设备服务5个UE，第一设备在一段时间(例如，时间长度可以预设)内收到了这些UE中的一个或多个UE分别发送的上述请求消息，第一设备确定停止监听接入网设备对这些UE的寻呼，则第一设备向每个UE分别发送该响应消息。当UE收到该响应消息时，UE开始监听接入网设备对UE的寻呼。
可选地，在本申请的一个实施方式中，所述方法还包括：所述第一设备向所述接入网设备指示所述第一设备的信号质量等级，所述第一设备的信号质量等级有对应的业务最大重复发送次数。
可选地，第一设备还可以向接入网设备发送第一设备服务的终端的标识。接入网设备可以在所述第一设备的寻呼时机上以所述业务最大重复发送次数向第一设备发送寻 呼。该寻呼可以包含第一设备标识和/或第一设备服务的终端设备的标识。其中，第一设备的信号质量等级可以由第一设备根据第一设备确定的接入网设备下的小区信号质量和接入网设备发送的信号质量门限值确定。在该实施方式中，接入网设备不用按照预设的最大重复次数向中继设备发送寻呼，而是对应不同信号质量等级的中继设备采用不同的重复发送次数，节约接入网设备的信令开销。
采用本申请实施例提供的通信方法，在中继场景中，通过中继设备接入网络的UE根据其所处位置的信号质量确定是否监听接入网设备的寻呼，向中继设备和/或接入网设备上报用于指示所述UE对所述寻呼的监听状态的信息，中继设备根据获得的UE对所述寻呼的监听状态的信息确定是否协助监听所述寻呼，从而能够灵活选择适应当前网络条件的寻呼方式，节约终端及中继设备的功耗，减少终端及中继设备、接入网设备间的信令开销。
可以理解，在中继场景下的其他UE与网络侧的通信流程中，例如在系统消息的接收流程中，或者数据的发送/接收中，也可以由UE根据信号质量确定与其直接通信的通信对端，例如，当中继设备的信号质量优于接入网设备的信号质量，则UE选择中继设备作为通信对端，例如从中继设备接收接入网设备发送的系统消息或者通过中继设备进行数据收发；当接入网设备的信号质量优于中继设备的信号质量，则UE选择接入网设备作为通信对端，例如直接从接入网设备接收系统消息或者进行数据收发。在该实施方式中，UE可以确定是否通过中继设备接收接入网设备的系统消息，或者是否通过中继设备进行与接入网设备的数据收发。可以理解的是，对于由UE根据信号质量确定与其直接通信的通信对端的方式以及后续的流程与前面所描述的UE根据信号质量确定监听接入网设备对UE的寻呼的方式类似，所不同的是，第一消息的作用发生了变化，例如，所述第一消息可以用于指示UE是否通过中继设备接收接入网设备的系统消息，或者是否通过中继设备进行与接入网设备的数据收发，相应的，接收端在接收到第一消息后会执行相应的处理，可以参照寻呼场景下的描述，不做赘述。
下述图3-图5所示实施例是在图2所示实施例基础上对本申请提供的通信方法的进一步解释与说明，已说明的内容不做赘述。在如下实施例中，以中继设备为中继节点，接入网设备为gNB为例进行说明，UE通过中继节点接入gNB。
图3是本申请实施例提供的一种通信方法的流程示意图。在图3所示的方法中，UE将根据信号质量生成的第一消息发送给中继节点及gNB，由中继节点根据所述第一消息确定是否协助监听接入网设备对UE的寻呼。
该方法包括：
S301：UE测量对应于gNB的第一信号质量。
具体地，UE测量gNB管理的该UE的服务小区的信号质量，可以参照图2所示实施例中的相关描述，不做赘述。
S302：UE根据所述第一信号质量确定第一消息。
其中，所述第一消息用于指示UE对gNB的寻呼的监听状态。关于所述第一消息的具体描述可以参照图2所示实施例中的相关内容，不做赘述。所述gNB的寻呼包括gNB对所述UE在内的一个或多个UE的寻呼。
在一些示例中，UE可以根据所述第一信号质量与某一阈值的比较结果，或者根据第一信号质量对应的第一信号质量等级与某一阈值的比较结果，或者根据所述第一信号质量与对应于中继设备的信号质量的比较结果，或者根据所述第一信号质量等级与对应于中继设备的信号质量等级等方式来确定是否监听gNB对所述UE的寻呼，进而确定所述第一消息，下文将对这些确定第一消息的方式做具体描述。
S303：UE向中继节点发送所述第一消息。
相应地，中继节点接收所述第一消息。
S304：UE向gNB发送所述第一消息。
相应地，gNB接收所述第一消息。
此处，由UE直接通知gNB该UE是否监听gNB对其的寻呼，无需通过中继节点转发，从而可以节约信令开销。
其中，S304为可选的步骤，关于gNB在何种场景下接收所述第一消息以及接收所述第一消息之后的处理可以参见图2所示实施例中接入网设备获取第一消息的相关描述，不做赘述。
S305：中继节点根据所述第一消息确定是否协助监听所述寻呼。
关于中继节点如何确定是否协助监听gNB的寻呼的具体方式可以参考图2所示实施例中的相关内容，不做赘述。
可以理解，S305在S303之后执行，当S304也被执行时，S305与S304没有执行的先后顺序区分。
可选地，所述方法还包括S306：中继节点向UE发送响应消息。
本申请实施例对所述响应消息的具体形式和内容不做限定。可选地，所述响应消息包含指示信息，所述指示信息用于指示所述UE是否监听所述寻呼。例如，当中继节点根据UE的指示或者接受UE的请求确定协助监听gNB对UE的寻呼，则中继节点可以向UE发送响应消息，该响应消息用于指示UE不直接监听所述寻呼。比如，该响应消息中可以包含指示信息，用于指示UE不直接监听所述寻呼。又例如，当中继节点不接收UE的请求，确定不对接入网设备的寻呼进行监听，中继节点也可以向UE发送响应消息，该响应消息用于指示UE直接监听所述寻呼。比如，该响应消息中可以包含指示信息，用于指示UE直接监听所述寻呼。
一种可能的实现方式中，当中继节点不改变现有的监听状态时，向UE发送响应消息，可以防止UE频繁改变UE当前的监听状态。例如，当前由UE自己监听接入网设备的寻呼，当UE向中继节点发起请求，请求中继节点协助监听该UE的寻呼时，若中继节点不接收UE的请求，即中继节点不同意协助监听，那么中继节点的监听状态不发生改变，则中继节点可以向UE发送响应消息，通知UE中继节点不监听所述寻呼，相应地，UE继续监听所述寻呼；当中继节点同意协助监听，则可以不向UE发送上述响应消息， 由中继节点直接执行改变监听状态的操作，节约UE与中继节点间的信令开销。又例如，当前由中继节点监听所述寻呼，若中继节点接收UE的请求，即中继节点同意协助监听，那么中继节点的监听状态不发生改变，则中继节点可以向UE发送响应消息，通知UE由中继节点监听所述寻呼。
可选地，所述方法还包括S307：中继节点向gNB发送第二消息，所述第二消息用于向gNB指示该中继节点协助监听或者不协助监听gNB对该UE的寻呼。
可替代地，所述第二消息也是序列或者参考信号等信息，本申请实施例对此不做限定。
当S306与S307均执行时，S306和S307没有执行的先后顺序区分，可以先执行S306再执行S307；也可以先执行S307再执行S306，也可以同时执行S306及S307，不做限定。
当S305中，中继节点确定协助监听gNB对UE的寻呼，所述方法还包括，
S308：中继节点协助监听所述寻呼。
S309：中继节点向UE转发监听到的gNB对UE的寻呼。
相应地，UE监听中继节点转发的寻呼。
UE对gNB的寻呼进行间接监听，从而从中继节点接收gNB发送的寻呼消息。
可以理解，S308-S309与S306、S307没有执行的先后顺序区分，不做赘述。
本申请实施例对中继节点协助监听gNB对UE的寻呼的模式不做特别限定。可选地，中继节点可以在中继节点的寻呼时机上监听接入网设备对被协助监听UE的寻呼，相应地，gNB仅在中继节点的寻呼时机上发送对被协助监听UE的寻呼消息；或者，中继节点可以在每个被协助监听的UE的寻呼时机上监听gNB对UE的寻呼，相应地，gNB在每个被协助监听的UE的寻呼时机上分别发送寻呼消息。
可选地，中继节点转发的寻呼中包含用于在所述中继节点下唯一识别所述UE的指示信息。可选地，所述指示信息是指示位或者终端标识。具体地，中继节点可以为其管理的每个UE分配该中继节点下唯一的标识，每个标识可以固定占用一个或多个比特位，则每个UE可以根据固定位置的比特位上对应的信息来确定是否有gNB对该UE的寻呼。
采用本申请实施例提供的通信方法，在中继场景中，UE通过测量到的信号质量，指示或请求中继节点改变对gNB的寻呼的监听状态，通过动态改变寻呼方式，减少gNB、中继节点以及UE相互之间的信令开销，以及各个设备的功耗。
以下将列举几种S302中UE确定所述第一消息的具体方式(如方式一至方式三)。
例如，方式一：UE可以比较所述第一信号质量与第一阈值，根据比较结果确定UE是否监听gNB对UE的寻呼，进而生成所述第一消息。
其中，所述第一阈值可以由gNB通知给UE；或者，所述第一阈值可以根据信号质量等级门限的划分情况来确定。例如，所述第一阈值可以等于信号质量等级门限中的一个；或者所述第一阈值可以为UE预设。第一阈值可以由gNB进行周期性更新或者基于事件 触发更新，并将更新后的第一阈值通知给UE，所述通知给UE可以是gNB直接发送给UE，或者通过中继节点转发，本申请实施例对此不做限定。
可选地，当第一信号质量大于第一阈值时，UE确定所述第一消息用于指示所述UE直接监听所述寻呼。
可选地，当第一信号质量小于第一阈值时，UE确定所述第一消息用于指示所述UE不直接监听所述寻呼。
又例如，方式二：UE可以根据所述第一信号质量对应的第一信号质量等级，确定所述第一消息。其中，所述第一信号质量等级可以用CE等级表示。
在本申请实施方式中，不同的信号质量等级可以对应于不同的业务最大重复发送次数，例如，所述第一信号质量等级对应于第一业务最大重复发送次数。所述业务最大重复发送次数可以由gNB预先设置且可以由gNB进行更改，更改后的业务最大重复发送次数可以作为参数下发给UE。
所述第一信号质量等级可以根据所述第一信号质量以及gNB发送的配置信息来确定，所述配置信息包括至少一个信号质量门限值。例如，UE可以将其实际测量的服务小区的信号质量和所述配置信息中的信号质量门限值做比较，从而确定所述第一信号质量等级。
其中，所述配置信息可以是信号质量判断配置信息或者覆盖增强等级判断配置信息。可选地，所述配置信息中还包括迟滞时间和/或质量偏置等信息，用于与上述信号质量门限值配合使用，可以减少时间或者信号质量的波动对判断结果的影响，提升判断信号质量等级的精确性。可选地，上述配置信息包含在gNB发送的广播消息中，UE通过接收上述广播消息获取所述配置信息；或者，UE可以接收中继节点从gNB转发的包含配置信息的消息或者信令。本申请实施例对UE如何获取上述配置信息的方式不做特别限定。
可选地，所述配置信息中的信号质量门限值可以由gNB根据网络通信条件更新，例如根据UE上报的测量结果进行更新，并将更新后的门限值下发给UE。UE可以根据最新的信号质量门限值来更新信号质量等级，并将更新后的信号质量等级上报给gNB，或者通过中继节点发送给gNB。
可以理解，所述信号质量门限值的个数与信号质量等级的个数对应。例如，若将信号质量等级个数记为N，信号质量门限值个数记为M，则N至少等于M+1，其中，M大于或等于1，N大于或者等于2。例如，划分2个信号质量等级，则信号质量门限值至少为1个；或者，划分3个信号质量等级，则信号质量门限值至少为2个；或者，划分4个信号质量等级，则信号质量门限值至少为3个。信号质量门限值的个数根据信号质量等级划分的数量确定，本申请实施例不做特别限定。一般地，可以将N个信号质量等级划分为等级0，等级1，……，等级N-1，等级0对应信号质量最好的情况，依次递减，等级N-1对应信号质量最差的情况。
以将gNB的覆盖区域划分4个不同的信号质量等级为例，记为{level 0，level 1，level 2，level 3}，从level 0至level 3对应的信号质量由高到低。对应地，所述配置信息中可以包含三个信号质量门限值，记为{门限1，门限2，门限3}。假设门限1＝100，门限2＝60， 门限3＝30，当UE测量到的下行信号质量高于100，则UE确定该UE处于level 0的区域；当UE测量到的下行信号质量低于100但高于60时，则UE确定该UE处于level 1的区域；当UE测量到的下行信号质量低于60且高于30时，则UE确定该UE处于level 2的区域；当UE测量到的下行信号质量低于30时，则UE确定该UE处于level 3的区域。其中，level 0对应的业务最大重复发送次数为1次，例如接入网设备可以只发送一次寻呼消息，即可认为UE已成功接收；level 1对应的业务最大重复发送次数为50次，网络侧最多发送50次寻呼消息，当50次寻呼消息发送完毕后，即认为UE已成功接收，level 2及level 3的业务最大重复发送次数不做赘述。
在方式二中，UE可以比较所述第一信号质量等级与第二阈值，根据比较结果确定UE是否直接监听gNB对UE的寻呼，进而生成所述第一消息。
其中，所述第二阈值可以是gNB通知给UE的，所述第二阈值也可以是UE自己确定的，其中，所述第二阈值可以由gNB或UE根据网络中信号质量等级的个数和每个等级对应的值来确定，例如，所述第二阈值可以等于信号质量等级中的一个等级对应的值。在另一个实施方式中，仍以gNB的覆盖区域划分了{level 0，level 1，level 2，level 3}4个信号质量等级为例，从level 0至level 3对应的信号质量由高到低，每个等级对应的值假设为为{0,1,2,3}。作为一个具体的实施方式，假设第二阈值是1，且UE确定该UE处于level 0的区域，则level 0对应的值小于第二阈值，UE确定可以监听gNB对它的寻呼；若UE确定该UE处于{level 1，level 2，level 3}中的任意一个区域，由于这三个等级对应的值大于或等于1，则UE确定可以不监听gNB对它的寻呼，从而请求第一设备监听该寻呼。可选地，所述第二阈值也可以不是整数，例如可以是任意两个信号质量等级对应的值的区间内的任意一个数，不做赘述。
可选地，当所述第一信号质量等级小于第二阈值，UE确定直接监听gNB对该UE的寻呼，进而生成相应的第一消息，用于指示UE对所述寻呼的监听状态为直接监听。
在本申请的一个实施方式中，当UE确定直接监听gNB的寻呼，UE可以根据所述第一信号质量等级例如CE等级，确定对所述寻呼的最大监听次数，UE实际监听寻呼的次数少于或等于所述最大监听次数。不同的CE级对应不同的最大监听次数，所述最大监听次数与所述第一信号质量等级对应的业务最大重复发送次数相同或有对应关系。信号质量越好的CE等级对应的业务最大重复发送次数越少，相应的，UE确定的最大监听次数也越少。比如CE等级0的UE只监听1次寻呼，CE等级1的UE最多监听50次寻呼或者在监听过程中成功接收到寻呼消息为止。
可选地，当所述第一信号质量等级大于第二阈值，UE确定UE不直接监听gNB对该UE的寻呼，进而生成相应的第一消息，用于指示UE对所述寻呼的监听状态为不直接监听。
由于不同的信号质量等级对应不同的业务最大重复发送次数，因此，在另一个实施方式中，UE也可以根据已确定的该UE的信号质量等级对应的业务最大重复发送次数来确定所述第一消息。例如，当所述第一信号质量等级对应的业务最大重复发送次数小于第三阈值，UE向中继节点发送用于指示所述UE直接监听所述寻呼的第一消息，相应地，所述中继节点不监听所述寻呼；或者，当所述信号质量等级对应的业务最大重复发送次 数大于或等于所述第三阈值，UE向中继节点发送用于指示所述UE不直接监听所述寻呼的第一消息，相应地，中继节点收到该第一消息后，则监听所述寻呼。
可选地，如果所述第一信号质量等级等于第二阈值或者所述第一信号质量等级对应的业务最大重复发送次数等于第三阈值，则UE可以根据信号质量等级的绝对值确定是否需要对接入网设备的寻呼进行监听。例如，当UE确定其信号质量等级为level 0，且第二阈值为0，由于level 0表示信号质量最佳，则UE可以对所述寻呼进行监听。当UE确定其信号质量等级为level 1，且第一阈值为1,则UE可以选择不监听所述寻呼，请求或者指示中继节点来监听。在一个实际的应用中，默认由中继节点监听寻呼并转发给UE，则在信号质量等级等于第二阈值或者信号质量等级对应的业务最大重复发送次数等于第三阈值时，除了UE处于level 0的情况，UE均可以维持不监听所述寻呼的状态。
再例如，方式三：UE除了测量对应于gNB的信号质量(如上述第一信号质量)之外，还可以测量对应于中继节点的信号质量，并将所述对应于中继节点的信号质量与所述第一信号质量一起用于与所述确定所述第一消息。
在方式三中，所述方法还可以包括S301a：UE测量对应于中继节点的第二信号质量。
所述第二信号质量是指中继节点的覆盖范围的信号质量，可以由UE进行测量，与第一信号质量的测量方式类似，不做赘述。当中继设备为中继终端时，由于中继终端会发射信号，UE可以测量中继终端的信号质量。
该步骤S301a与S301没有执行的先后顺序区分，可以先执行S301再执行S301a，也可以先执行S301a再执行S301，也可以同时执行S301与S301a，不做限定。
可以理解的是，根据获取得到的第二信号质量，也可以确定得到对应的第二信号质量等级。而第二信号质量等级的确定方式与第一信号质量等级类似，第二信号质量等级也存在对应的第二业务最大重复发送次数。
在获取第二信号质量后，UE可以结合第一信号质量，确定UE对gNB对该UE的监听状态。例如可以是根据第一信号质量和第二信号质量来确定所述监听状态，也可以是根据第一信号质量等级和第二信号质量等级来确定所述监听状态。下面对不同的确定方式分别进行说明。
在一个实现方式中，UE可以比较第一信号质量与第二信号质量，根据比较结果确定UE是否直接监听gNB对UE的寻呼，进而生成所述第一消息，比如可以有如下实现方式：
(1)当所述第一信号质量小于所述第二信号质量时，UE确定所述第一消息用于指示UE不直接监听gNB对UE的寻呼。
(2)当所述第一信号质量大于所述第二信号质量时，UE确定所述第一消息用于指示UE直接监听gNB对UE的寻呼。
(3)当所述第一信号质量小于所述第二信号质量，且所述第一信号质量与所述第二信号质量的差值的绝对值大于或等于第四阈值时，UE确定所述第一消息用于指示UE不直接监听gNB对UE的寻呼。
(4)当所述第一信号质量大于所述第二信号质量，且所述第一信号质量与所述第二信号质量的差值的绝对值大于或等于第四阈值时，UE确定所述第一消息用于指示UE直 接监听gNB对UE的寻呼。
(5)当所述第一信号质量等于所述第二信号质量，UE可以不改变当前的监听状态，对应地，所述第一消息可以用于指示UE当前的监听状态。
其中，上述第四阈值可以是预先配置给UE的，也可以是UE从gNB获取的，不做限定。
在另一个实现方式中，UE可以比较所述第一信号质量等级与所述第二信号质量等级，或者UE比较所述第一信号质量等级对应的第一最大业务最大重复发送次数和第二信号质量等级对应的第二最大业务最大重复发送次数，根据比较结果确定UE是否直接监听gNB对UE的寻呼，进而生成所述第一消息，比如可以有如下实现方式：
(1)当第一信号质量等级小于第二信号质量等级时，或者，当第一信号质量等级对应的第一最大重复发送次数小于第二信号质量等级对应的第二最大重复发送次数时，UE向中继节点或gNB发送用于指示所述UE直接监听所述寻呼的第一消息。
(2)当所述第一信号质量等级大于所述第二信号质量等级时，或者，当第一信号质量等级对应的第一最大重复发送次数大于第二信号质量等级对应的第二最大重复发送次数时，UE向中继节点或gNB发送用于指示所述UE不直接监听所述寻呼的第一消息。
(3)当第一信号质量与第二信号质量不同，但第一信号质量对应的第一质量等级与第二信号质量对应的第二质量等级相同，则UE可以不改变该UE对gNB的寻呼的监听状态，即可以维持现有的寻呼方式。例如，CE等级1对应的信号质量范围是[5,10]，假设UE测量的中继节点的信号质量是6，UE测量的基站的信号质量是7，则UE对应中继节点和对应基站的CE等级是一样的，无需改变现有的寻呼方式。UE可以向中继节点发送指示UE当前的监听状态的第一消息。
可以理解，本申请实施例中以信号质量等级越小代表信号质量越好来举例。反之，也可以以信号质量等级越大代表信号质量越好。例如，当所述第一信号质量等级大于某一阈值，UE可以向中继节点发送用于指示该UE监听gNB对UE的寻呼的第一消息；或者，当所述第一信号质量等级小于该阈值，UE向中继节点发送用于指示该UE不直接监听所述寻呼的第一消息。又例如，当所述第一信号质量等级大于所述第二信号质量等级，UE可以向中继节点发送包含用于指示该UE监听所述寻呼的第一信息的第一消息；或者，当所述第一信号质量等级小于所述第二信号质量等级，UE可以向中继节点发送包含用于指示该UE不直接监听所述寻呼的第一信息的第一消息，不做赘述。
采用上述各类列举的确定所述第一消息的方式，UE可以通过自身所处位置的信号质量向中继点准确指示所述UE对gNB的寻呼的监听状态，从而能够动态调整网络中的寻呼方式，其中，将信号质量等级(例如CE等级)用于确定所述第一消息，可以避免过于频繁改变寻呼方式，减少信令开销，节约通信资源。
图4是本申请实施例提供的一种通信方法的流程示意图。在图4所示的方法中，UE将根据信号质量生成的第一消息发送给中继节点，由中继节点根据所述第一消息确定是否协助监听接入网设备对UE的寻呼。中继节点可以向gNB发送中继节点是否协助监听 接入网设备对UE的寻呼的指示信息。该方法包括：
S401:UE测量对应于gNB的第一信号质量。
关于第一信号质量的相关描述可以参照本申请其他实施例的相关内容，不做赘述。
S402：UE根据所述第一信号质量确定第一消息。
其中，所述第一消息用于指示UE对gNB的寻呼的监听状态。
关于第一消息的具体内容描述可以参照本申请其他实施例的相关内容，不做赘述。
可选地，UE根据所述第一信号质量与某一阈值的比较结果、或者根据第一信号质量对应的第一信号质量等级与某一阈值的比较结果，确定是否监听gNB对所述UE的寻呼，进而确定所述第一消息，更详细的描述可以参照本申请其他实施例，例如图3所示实施例中的相关内容，不做赘述。
S403：UE向中继节点发送所述第一消息。
S404：中继节点根据所述第一消息确定是否协助监听所述寻呼。
关于中继节点如何确定是否协助监听所述寻呼的具体方式可以参照本申请其他实施例中的相关内容，不做赘述。
S405：中继节点向UE发送响应消息。
关于所述响应消息的具体描述可以参照图3所示实施例中的相关内容，不做赘述
S406：中继节点向gNB发送所述第一消息。
其中，S405、S406为可选的步骤。可以理解，步骤S406在中继节点收到所述第一消息后即可执行，例如可以在S404或S405之前执行。上述S404-S406的执行顺序仅是一种举例，不构成对本申请实施例的任何限定。
作为S406的替代步骤，所述方法还可以包括，S406’：中继节点向gNB发送第二消息，所述第二消息用于向gNB指示该中继节点协助监听或者不协助监听gNB对该UE的寻呼。
在上述实施方式中，中继节点既可以将UE对所述寻呼的监听状态通知给gNB，如步骤S406；也可以将自己对gNB对UE的寻呼的监听状态通知给gNB，如步骤S406’，使得gNB能及时获知网络中的寻呼方式是否发生改变。
关于中继节点确定协助监听gNB对UE的寻呼后，监听和转发所述寻呼的过程可以参照图3所示实施例中的步骤S308至S309的描述，不做赘述。
图5是本申请实施例提供的一种通信方法的流程示意图。在图4所示的方法中，UE将根据信号质量生成的第一消息发送给gNB，再由gNB将所述第一消息转发给中继节点，进而，由中继节点根据所述第一消息确定是否协助监听接入网设备对UE的寻呼。该方法包括：
S501:UE测量对应于gNB的第一信号质量。
S502：UE测量对应于中继节点的第二信号质量。
S503：UE根据所述第一信号质量以及所述第二信号质量确定第一消息。
其中，所述第一消息用于指示UE对gNB的寻呼的监听状态。
关于第一消息的具体内容描述可以参照本申请其他实施例的相关内容，不做赘述。

S603：所述接入网设备在所述第一设备的寻呼时机上以所述业务最大重复发送次数向所述第一设备发送寻呼。
其中，所述寻呼包括接入网设备对所述第一设备的寻呼，和/或，接入网设备对所述第一设备服务的UE的寻呼。
可选地，第一设备可以采用显示指示或者隐式指示的方式通知接入网设备所述第一设备的信号质量等级，不做限定。例如，第一设备向接入网设备发送包含信号质量等级信息的消息；或者，向接入网设备发送可以映射到其信号质量等级的指示信息。比如，第一设备发送和信号质量等级对应的随机接入配置信息。具体地，随机接入配置信息包括随机接入前导、随机接入资源的至少一种。可以理解，第一设备可以接收接入网设备发送的信号质量等级和随机接入配置信息的对应关系，从而确定其信号质量等级对应的随机接入配置信息。
可选地，所述方法还包括：所述第一设备从所述接入网设备接收寻呼配置信息，所述寻呼配置信息用于确定所述第一设备的寻呼时机。
其中，所述寻呼配置信息包括用于确定寻呼时机的参数。用于确定寻呼时机的参数包括：寻呼周期、寻呼周期内的寻呼帧的个数、寻呼帧偏移、每个寻呼帧上寻呼时机的格式、寻呼时机的监听时机等参数的至少一种。

作为一种可能的实现方式，所述寻呼配置信息包括用于确定信号质量等级和寻呼时机的对应关系的指示信息。相应地，第一设备可以直接监听所述第一设备的信号质量等级对应的寻呼时机上的寻呼。第一设备可以不监听根据其核心网标识或核心网标识相关信息确定的寻呼时机上的寻呼。在该实现方式中，由于第一设备可以根据第一设备的信号质量等级和接收的寻呼配置信息直接确定第一设备的寻呼时机，因此，接入网设备也不需要向第一设备发送用于确定寻呼时机的第一设备的寻呼标识。
第一设备根据所述寻呼配置信息确定所述第一设备的寻呼时机，或者当接入网设备为第一设备分配寻呼标识，第一设备根据所述寻呼配置信息与所述寻呼标识确定所述第一设备的寻呼时机。从而，第一设备可以在所述寻呼时机上以所述业务最大重复发送次数接收所述接入网设备的寻呼。
其中，接入网设备向第一设备发送的寻呼消息中包含所述第一设备的核心网标识，所述寻呼标识，所述第一设备的接入网标识，所述第一设备服务的终端设备的接入网标识，所述第一设备服务的终端设备的核心网标识中的中的一种或者多种标识。

其中，所述信号质量等级对应一个最大业务重复发送次数。
S702：中继节点向gNB发送指示该中继节点的信号质量等级的指示信息。
相应地，gNB接收上述指示信息，获取中继节点的信号质量等级。

S706：gNB在所述寻呼时机上以所述业务最大重复发送次数向中继节点发送寻呼。
其中，所述寻呼可以是gNB对中继节点的寻呼，也可以是gNB对该中继节点服务的被协助寻呼的UE的寻呼。gNB也可以同时对中继节点及对该中继节点服务的被协助寻呼的UE发起寻呼。
具体地，gNB可以根据中继节点的信号质量等级，确定在该信号质量等级对应的寻呼时机内需要重复发送寻呼的最大次数，随后，gNB在该寻呼时机内以该信号质量等级对应的最大寻呼重复发送次数来发送寻呼。比如在CE等级0对应的寻呼时机，gNB仅发送1次寻呼消息，在CE等级1对应的寻呼时机，gNB最多重复发送50次寻呼消息，50次寻呼消息发送完毕即认为中继节点已成功接收，或者，gNB收到中继节点发送的响应消息后停止发送寻呼。
gNB可以给向具有相同信号质量等级的中继节点配置可以确定相同寻呼时机的寻呼标识。可选地，gNB可以向具有相同的信号质量等级的中继节点配置相同的寻呼标识，或者配置不同的寻呼标识且这些寻呼标识可以计算得出相同的寻呼时机。
S707：中继节点在所述寻呼时机上重复接收所述gNB的寻呼。
具体地，中继节点可以重复接收所述gNB的寻呼，直到成功接收为止；或者当重复接收次数达到中继节点的信号质量等级对应的最大业务最大重复发送次数，停止接收所述gNB的寻呼。

采用本申请实施例提供的通信方法，gNB为中继节点配置寻呼标识，并根据中继节点的信号质量等级对应的业务最大重复发送来发送寻呼，避免因gNB无法确定寻呼目标的位置信息而在每个寻呼时机上按相同的寻呼重复次数来发送寻呼，从而减少寻呼过程的信令开销。
