首先，对本申请涉及的部分通信方式和用语进行解释说明，以便于本领域技术人员理解：
(一)通信方式
(1)蜂窝网络通信
传统的无线通信采用蜂窝网络通信方式。在蜂窝网络通信方式中，终端和网络设备通过空中接口(例如Uu接口)进行上下行数据/控制信息的传输。
图1为通信场景示例图一，该通常场景为蜂窝网络通信场景。如图1所示，以网络设备包括基站和核心网、终端包括终端1和终端2为例，终端1和终端2分别通过Uu接口与基站进行通信连接。
(2)直接通信
直接通信是指邻近的终端可以在近距离范围内通过直接通信链路(又称为侧行链路，又称为Sidelink或者PC5)进行数据传输的方式。直接通信链路对应的无线接口称为直接通信接口(又称为Sidelink接口或者PC5接口)。

(二)用语
(1)寻呼(paging)
终端的无线资源控制(Radio Resource Control，RRC)处于为空闲(IDLE)状态或者处于非激活(INACTIVE)状态时，即终端处于RRC_IDLE状态或者RCC_INACTIVE状态时，网络设备可寻呼该终端，终端监听到网络设备的寻呼消息后，可由RRC_IDLE状态或者RCC_INACTIVE状态，转换为RRC链接的激活(RRC_ACTIVE)状态。
(2)不连续接收(Discontinuous Reception，DRX)机制：在DRX机制中，终端可在每一个寻呼周期的寻呼时机(paging occasion，PO)，在空中接口处进行寻呼消息的监听。
(3)寻呼周期：在DRX机制中，针对接收端而言(例如终端)，寻呼周期又称为不连续接收周期，简称DRX周期，用于指示接收端每隔一个寻呼周期进行寻呼消息的监听；针对发送端(例如网络设备)而言，DRX机制对应不连续发送(Discontinuous Transmission，DTX)机制，寻呼周期被称为不连续发送周期，简称DTX周期，用于指示发送端按照寻呼周期进行寻呼消息的发送。
(4)寻呼帧(Paging Frame，PF)：一个寻呼周期中包括一个或多个寻呼帧，一个寻呼帧为一个无线帧，包括多个子帧，一个寻呼帧可以包括一个或多个寻呼时机或者可以包括一个寻呼时机的起点。
(5)寻呼时机(PO，paging occasion)：物理下行链路控制信道(Physical Downlink Control Channel，PDCCH)的监测时机(Monitoring Occasion)的集合，可以有多个时隙。在寻呼时机。终端在每一个寻呼周期的寻呼时机进行寻呼消息的监听。若一个寻呼周期内寻呼时机为多个，则可以在一个寻呼周期内对终端进行多次重复寻呼，提高寻呼的成功率。
(6)***帧号(System Frame Number，SFN)：在空中接口处的无线帧号，例如，在Uu接口处的无线帧号。
(7)直接通信接口帧号(Direct Frame Number，DFN)：在直接通信接口处的无线帧号。
(8)第一终端：中继场景中的被中继终端，又称远程终端。

其中，第二终端与第一终端通过直接通信接口进行通信，第二终端与网络设备通过空中接口进行通信。
(10)侧链寻呼时机(sidelink paging occasion，SLPO)：第一终端在与第二终端通信的直接通信接口进行寻呼消息监听的时机，也是第二终端在直接通信接口进行寻呼消息发送所要遵循的时机，该寻呼消息是指网络设备寻呼第一终端的寻呼消息。
(11)空中寻呼时机：第二终端在空中接口监听网络设备寻呼第一终端的寻呼消息的时机，也是网络设备通过空中接口寻呼第一终端所要遵循的时机。
(12)第一偏移值：第一终端与第二终端之间的直接通信接口对应的寻呼帧的偏移量，换句话说，第一偏移值是指在直接通信接口进行寻呼消息的监听或发送时用于寻呼帧测定的偏移量。
(13)第二偏移值：网络设备与终端之间的空中接口对应的寻呼帧的偏移量，换句话说，第二偏移值是指在空中接口进行寻呼消息的监听或发送时用于寻呼帧测定的偏移量。
(14)接口间无线帧偏差：空中接口的SFN与直接通信接口的DFN之间的时间偏差，其取值与直接通信接口的时钟同步源相关。
(15)终端的标识：用于区分不同的终端。
可选的，终端的标识根据终端的临时用户识别码(Temporary Mobile Subscriber Identity，TMSI)确定，例如，终端的标识为TMSI与1024进行求余运算(又称为mod运算)的结果。
可选的，若第一终端未在网络上进行注册，则第一终端的标识为默认标识，例如为零。
在未引入中继的通信场景中，处于RRC_IDLE或者RCC_INACTIVE的终端，可采用不连续接收(Discontinuous Reception，DRX)机制在空中接口处监听网络设备寻呼该终端的寻呼消息。
在引入中继的通信场景中，中继终端在空中接口同时监听网络设备寻呼中继终端的寻呼消息和网络设备寻呼被中继终端的寻呼消息，若监听到网络设备寻呼被中继终端的寻呼消息，则需要将该寻呼消息转发给被中继终端。目前，寻呼监听的方案大多针对空中接口，尚未相关方案，用于解决被中继终端如何进行寻呼消息的监听的问题。
为解决上述问题，本申请实施例提供了一种寻呼方法、装置及存储介质。在本申请中，第一终端根据DRX机制，确定在与第二终端进行通信的直接通信接口监听寻呼消息的时机，按照确定的时机，在直接通信接口监听来自网络设备的寻呼消息，实现了中继场景中被中继终端(即第一终端)对寻呼消息的监听，而且降低了被中继终端进行寻呼消息监听的功耗。
其中，本申请实施例所提供的方法和装置是基于同一申请构思的，由于方法和装置解决问题的原理相似，因此装置和方法的实施可以相互参见，重复之处不再赘述。
图4为本申请的一实施例提供的寻呼方法的流程示意图。如图4所示，该方法包括：
S401、第一终端根据DRX机制，确定侧链寻呼时机。
本步骤中，将DRX机制应用于寻呼时机的确定时，可确定终端在每个寻呼周期内的一个或多个寻呼时机，因此，基于DRX机制确定第一终端的侧链寻呼时机时，可确定第 一终端在每个寻呼周期内的一个或多个侧链寻呼时机。
S402、第一终端根据侧链寻呼时机，在直接通信接口监听寻呼消息。
本步骤中，在确定每个寻呼周期内的一个或多个侧链寻呼时机后，在各个侧链寻呼时机，第一终端在直接通信接口处监听第二终端转发的来自网络设备的寻呼消息。其中，第二终端若接收到网络设备寻呼第一终端的寻呼消息，则在侧链寻呼时机将该寻呼消息通过直接通信接口发送给第一终端。
本申请实施例中，在中继场景中，作为被中继设备的第一终端根据DRX机制，确定每个寻呼周期内的一个或多个侧链寻呼时机，在各侧链寻呼时机，在直接通信接口监听第二终端转发的来自网络设备的寻呼消息。因此，实现了中继场景中被中继终端对寻呼消息的监听，且被中继设备无需实时对寻呼消息进行监听，有效地降低了中继场景中寻呼消息监听的功耗。
图5为本申请的另一实施例提供的寻呼方法的流程示意图。如图5所示，该方法包括：
S501、第一终端根据DRX机制，确定侧链寻呼时机。
S502、第一终端按照侧链寻呼时机，在直接通信接口监听寻呼消息。
其中，S501和S502的实现原理和技术效果可参照前述实施例描述。
S503、第二终端接收网络设备寻呼第一终端的寻呼消息。
本步骤中，第二终端在空中接口处监听网络设备寻呼第一终端的寻呼消息，在网络设备通过空中接口发送该寻呼消息时，第二终端接收该寻呼消息。
其中，第二终端在空中接口处监听网络设备寻呼第一消息的寻呼消息时，例如可以采用实时监听、在固定时间进行监听，或者，可选的，第二终端按照DRX机制确定空中寻呼时机，按照空中寻呼时机，在空中接口处监听该寻呼消息，以节省第二终端的功耗。
S504、第二终端根据DTX机制，确定第一终端的侧链寻呼时机。
本步骤中，第二终端在接收到网络设备寻呼第一终端的寻呼消息后，根据DTX机制，确定离当前时间最近的针对第一终端的寻呼周期，并确定该寻呼周期中的侧链寻呼时机。
S505、第二终端按照侧链寻呼时机，通过直接通信接口向第一终端发送寻呼消息。
本步骤中，第二终端在确定侧链寻呼时机后，在侧链寻呼时机，通过直接通信接口，将网络设备寻呼第一终端的寻呼消息转发给第一终端。第一终端在接收到寻呼消息后，可由RCC_IDLE状态或者RCC_INACTIVE状态转换为RCC_ACTIVE状态，进而与网络设备进行上下行通信。
本申请实施例中，在中继场景中，第一终端按照侧链寻呼时机，在直接通信接口监听寻呼消息，第二终端接收到网络设备寻呼第一终端的寻呼消息之后，确定侧链寻呼时机，并按照侧链寻呼时机将寻呼消息转发给第一终端。实现了中继场景中被中继终端的寻呼消息的监听和发送，被中继设备无需实时对寻呼消息进行监听，有效地降低了中继场景中寻呼消息监听的功耗。
DRX机制应用于寻呼时机的确定时，需要依据多个已配置的寻呼参数。
因此，在一些实施例中，基于DRX机制确定侧链寻呼时机时，可以根据多个已配置的寻呼参数(为便于区分，将用于确定侧链寻呼时机的寻呼参数称为第一寻呼参数)，确定侧链寻呼时机。
同样的，在一些实施例中，第二终端基于DRX机制确定空中寻呼时机时，也可以根 据多个已配置的寻呼参数(为便于区分，将用于确定空中寻呼时机的寻呼参数称为第二寻呼参数)，确定空中寻呼时机。
一示例中，第一寻呼参数包括寻呼周期、单个寻呼周期中寻呼帧的数量、第一偏移量、以及第一终端的标识。其中，不同的第一终端，寻呼周期、单个寻呼周期中寻呼帧的数量、第一偏移量相同，第一终端的标识不同，因此，依赖不同的第一终端的标识，可区分开不同的第一终端的侧链寻呼时机。
可选的，在第一寻呼参数包括寻呼周期、单个寻呼周期中寻呼帧的数量、第一偏移量、以及第一终端的标识的情形下，侧链寻呼时机包括寻呼周期中寻呼帧的DFN。此时，根据第一寻呼参数，确定侧链寻呼时机的过程，包括：根据寻呼周期、单个寻呼周期中寻呼帧的数量、第一偏移量、以及第一终端的标识，确定寻呼周期中寻呼帧的DFN。因此，第一终端可按照寻呼周期中寻呼帧的DFN，在直接通信接口进行寻呼消息的监听，第二终端在接收到网络设备寻呼第一终端的寻呼消息后，可按照寻呼周期中寻呼帧的DFN，在直接通信接口将寻呼消息转发给第一终端。
可选的，针对直接通信接口处寻呼消息的监听或发送，寻呼周期中寻呼帧的DFN的确定公式可表示为：(DFN+SLPF_offset)mod T＝(T div N)*(UE_ID mod N)。
其中，SLPF_offset表示第一偏移量，T表示寻呼周期，N表示单个寻呼周期中寻呼帧的数量，UE_ID表示第一终端的标识，div运算表示整除运算，mod运算表示取余运算。
又一示例中，第一寻呼参数在包括寻呼周期、单个寻呼周期中寻呼帧的数量、第一偏移量、以及第一终端的标识之外，还可包括单个寻呼周期中的寻呼次数。其中，单个寻呼周期中的寻呼次数，即单个寻呼周期中寻呼消息的重复传输次数。假设单个寻呼周期中寻呼次数Ns，则在单个寻呼周期中可对第一终端进行Ns次寻呼，即第二终端与第一终端之间可进行Ns次的寻呼消息的传输，以提高寻呼成功率。
可选的，侧链寻呼时机包括寻呼周期中每次寻呼的时机。此时，根据第一寻呼参数，确定侧链寻呼时机的过程，包括：
根据寻呼周期、单个寻呼周期中寻呼帧的数量、第一偏移量、以及第一终端的标识，确定寻呼周期中寻呼帧的DFN；根据单个寻呼周期中寻呼帧的数量、单个寻呼周期中的寻呼次数、以及第一终端的标识，确定寻呼周期中第一次寻呼对应的DFN；根据寻呼周期中寻呼的DFN和寻呼周期中第一次寻呼对应的DFN，确定寻呼周期中每次寻呼的时机。
因此，第一终端按照寻呼周期中每次寻呼的时机，在直接通信接口监听寻呼消息，第二终端在接收到网络设备寻呼第一终端的寻呼消息后，可按照寻呼周期中每次寻呼的时机，在直接通信接口将寻呼消息转发给第一终端。
其中，针对直接通信接口处寻呼消息的监听或发送，根据寻呼周期、单个寻呼周期中寻呼帧的数量、第一偏移量、以及第一终端的标识，确定寻呼周期中寻呼帧的DFN的公式，可采用前述相应公式，不再赘述。
可选的，针对直接通信接口处寻呼消息的监听或发送，根据单个寻呼周期中寻呼帧的数量、单个寻呼周期中的寻呼次数、以及第一终端的标识，确定寻呼周期中第一次寻呼对应的DFN的公式可表示为：
i_s＝floor(UE_ID/N)mod Ns，其中，floor函数表示向下取整，Ns为单个寻呼周期中的寻呼次数,i_s表示第一次寻呼对应的子帧在寻呼帧中的位置，进而可以确定第一次寻呼 对应的DFN，即确定第一次寻呼的时机。
根据寻呼周期中寻呼帧的DFN和寻呼周期中的寻呼周期中第一次寻呼对应的DFN，确定剩余次的寻呼的时机，例如，按照固定的时间间隔来确定剩余次的寻呼的时机。因此，得到每次寻呼的时机。
作为示例的，第二终端在第一次向第一终端发送寻呼消息后，可以通过串行通信接口(Serial Communication Interface，SCI)中的时间资源分配(Time resource assignment)向第一终端指示重复的寻呼消息所在的时域信息。
一示例中，第二寻呼参数包括寻呼周期、单个寻呼周期中寻呼帧的数量、第二偏移量、第一终端的标识、以及单个寻呼周期中的寻呼次数。第一寻呼参数与第二寻呼参数相比较，其中，寻呼周期相同、单个寻呼周期中寻呼帧的数量相同、第一终端的标识相同，单个寻呼周期中的寻呼次数相同。根据第二寻呼参数，确定空口寻呼时机的过程，包括：
针对空中接口处寻呼消息的监听或发送，根据寻呼周期、单个寻呼周期中寻呼帧的数量、第二偏移量、以及第一终端的标识，确定寻呼周期中寻呼帧的SFN；根据单个寻呼周期中寻呼帧的数量、单个寻呼周期中的寻呼次数、以及第一终端的标识，确定寻呼周期中第一次寻呼对应的SFN；根据寻呼周期中寻呼的SFN和寻呼周期中第一次寻呼对应的SFN，确定寻呼周期中每次寻呼的时机。
可选的，针对空中接口处寻呼消息的监听或发送，寻呼周期中寻呼帧的SFN的确定公式可表示为：(SFN+PF_offset)mod T＝(T div N)*(UE_ID mod N)。
其中，PF_offset表示第一偏移量，T表示寻呼周期，N表示单个寻呼周期中寻呼帧的数量，UE_ID表示第一终端的标识。
可选的，针对空中接口处寻呼消息的监听或发送，确定寻呼周期中第一次寻呼对应的SFN的公式，可参照针对直接通信接口处寻呼消息的监听或发送中确定寻呼周期中第一次寻呼对应的DFN的公式，不再赘述。
一示例中，基于第一寻呼参数包括寻呼周期、单个寻呼周期中寻呼帧的数量、第一偏移量、以及第一终端的标识，或者，基于第一寻呼参数包括寻呼周期、单个寻呼周期中寻呼帧的数量、单个寻呼周期中的寻呼次数、第一偏移量、以及第一终端的标识，第一寻呼参数还包括如下至少一项：第二偏移量、接口间无线帧偏差，以进一步提高基于第一寻呼参数确定的侧链寻呼时机的合理性，提高寻呼效率和寻呼效果。
具体的，在根据第一寻呼参数，确定侧链寻呼时机时，可根据第一寻呼参数中的寻呼周期、单个寻呼周期中寻呼帧的数量、第一偏移量、第一终端的标识，以及根据第二偏移量、接口间无线帧偏差中的至少一种，确定寻呼周期中寻呼帧的SFN。在第一寻呼参数还包括单个寻呼周期中寻呼帧的数量时，还可进一步确定寻呼周期中每次寻呼的时机。下面，分别针对在第一寻呼参数中引入第二偏移量、接口间无线帧偏差进行描述：
(一)在第一寻呼参数中引入第二偏移量
若基于DRX确定的空口寻呼时机与基于DRX确定的侧链寻呼时机一致，则第二终端设备在一个寻呼周期接收到网络设备寻呼第一终端的寻呼消息后由于存在时间延迟，很可能无法立即在该寻呼周期将寻呼消息通过直接通信接口向第一终端发送该寻呼消息，而要等下一个寻呼周期，进一步增加了第二终端接收到寻呼消息至第二终端将该寻呼消息发送给第一终端之间的时长，影响寻呼效率和寻呼效果。为避免上述现象，可采用如下方式：
一种可能的实现方式：侧链寻呼时机与第二偏移量有关，换句话说，通过在第二偏移量的基础上添加上第一偏移量，来确定侧链寻呼时机。此时，空中寻呼时机采用了第二偏移量这一个偏移量，侧链寻呼时机采用了第一偏移量和第二偏移量这两个偏移量，使得空中寻呼时机与侧链寻呼时机错开。第二终端设备在空中接口的一个寻呼周期接收到网络设备寻呼第一终端的寻呼消息后，可在直接通信接口的时间接近的寻呼周期将寻呼消息发送给第一终端，而无需等待一个整周期，从而提高了寻呼效率和寻呼效果。
在侧链寻呼时机与第二偏移量有关时，基于第一寻呼参数包括寻呼周期、单个寻呼周期中寻呼帧的数量、第一偏移量、第二偏移量、以及第一终端的标识。此时，侧链寻呼时机包括寻呼周期中寻呼帧的SFN，可根据寻呼周期、单个寻呼周期中寻呼帧的数量、第一偏移量、第二偏移量、以及第一终端的标识，确定寻呼周期中寻呼帧的SFN。
可选的，针对直接通信接口处寻呼消息的监听或发送，根据寻呼周期、单个寻呼周期中寻呼帧的数量、第一偏移量、第一终端的标识、以及第二偏移量，确定寻呼周期中寻呼帧的SFN的公式，可表示为：(SFN+SLPF_offset+PF_offset)mod T＝(T div N)*(UE_ID mod N)。
可选的，第一寻呼参数包括寻呼周期、单个寻呼周期中寻呼帧的数量、单个寻呼周期中的寻呼次数、第一偏移量、第二偏移量、以及第一终端的标识时，侧链寻呼时机包括寻呼周期中每次寻呼的时机。此时，可根据第一寻呼参数，确定寻呼周期中每次寻呼的时机。
具体的，在根据寻呼周期、单个寻呼周期中寻呼帧的数量、第一偏移量、第一终端的标识、以及第二偏移量，确定寻呼周期中寻呼帧的SFN之后，根据单个寻呼周期中寻呼帧的数量、单个寻呼周期中的寻呼次数、以及第一终端的标识，确定寻呼周期中第一次寻呼对应的SFN，进而确定寻呼周期中每次寻呼的时机。其中，针对直接通信接口处寻呼消息的监听或发送中，确定寻呼周期中第一次寻呼对应的SFN，可参照前述相关公式，不再赘述。
另一种可能的实现方式：侧链寻呼时机与第二偏移量无关、且第一偏移量不等于第二偏移量，从而通过彼此不相等的第一偏移量和第二偏移量，使得空中寻呼时机与侧链寻呼时机错开。第二终端设备在空中接口的一个寻呼周期接收到网络设备寻呼第一终端的寻呼消息后，可在直接通信接口的时间接近的寻呼周期将寻呼消息发送给第一终端，而无需等待一个整周期，从而提高了寻呼效率和寻呼效果。此时，第一寻呼参数不包括第二偏移量，或者说，第一寻呼参数中的第二偏移量的取值为零。
(二)在第一寻呼参数中引入接口间无线帧偏差
考虑到空中接口的SFN和直接通信接口的DFN可能存在偏差，第二终端在空中接口处接收到网络设备寻呼第一终端的寻呼消息后，还需要按照直接通信接口的DFN确定侧链寻呼时机，为减少空中接口的SFN和直接通信接口的DFN之间的时间偏差在这个过程导致的时间误差，可在第一寻呼参数中引入接口间无线帧偏差。其中，接口间无线帧偏差用于表示空中接口的SFN和直接通信接口的DFN之间的时间偏差。
可选的，空中接口的SFN和直接通信接口的DFN之间的时间偏差的存在，主要原因是空中接口的时钟同步源和直接通信接口的时钟同步源的不同。空中接口的时钟同步源通常为网络设备，因此，若直接通信接口的时钟同步源为网络设备，则第一寻呼参数中不包括接口间无线帧偏差，或者，第一寻呼参数中的接口间无线帧偏差的取值为零。若直接通 信接口的时钟同步源为卫星，则第一寻呼参数中包括接口间无线帧偏差，接口间无线帧偏差的取值为空中接口的SFN和直接通信接口的DFN之间的时间偏差的实际值。
具体的，第一寻呼参数包括寻呼周期、单个寻呼周期中寻呼帧的数量、第一偏移量、接口间无线帧偏差以及第一终端的标识；或者，第一寻呼参数包括寻呼周期、单个寻呼周期中寻呼帧的数量、第一偏移量、第二偏移量、接口间无线帧偏差以及第一终端的标识；或者，第一寻呼参数包括寻呼周期、单个寻呼周期中寻呼帧的数量、单个寻呼周期中的寻呼次数、第一偏移量、接口间无线帧偏差以及第一终端的标识；或者，第一寻呼参数包括寻呼周期、单个寻呼周期中寻呼帧的数量、单个寻呼周期中的寻呼次数、第一偏移量、第二偏移量、无线帧偏差以及第一终端的标识。
以第一寻呼参数包括寻呼周期、单个寻呼周期中寻呼帧的数量、单个寻呼周期中的寻呼次数、第一偏移量、第二偏移量、接口间无线帧偏差以及第一终端的标识为例：根据第一寻呼参数确定侧链寻呼时机时，可根据寻呼周期、单个寻呼周期中寻呼帧的数量、第一偏移量、第二偏移量、接口间无线帧偏差以及第一终端的标识，确定寻呼周期中寻呼帧的SFN；再根据单个寻呼周期中寻呼帧的数量、单个寻呼周期中的寻呼次数、以及第一终端的标识，确定寻呼周期中第一次寻呼对应的SFN，进而确定寻呼周期中每次寻呼的时机。其中，可选的，根据寻呼周期、单个寻呼周期中寻呼帧的数量、第一偏移量、第二偏移量、接口间无线帧偏差以及第一终端的标识，确定寻呼周期中寻呼帧的SFN的公式，表示为：(SFN+DFN_SFN_offset+SLPF_offset+PF_offset)mod T＝(T div N)*(UE_ID mod N)。
其中，DFN_SFN_offset表示接口间无线帧偏差。
在一些实施例中，第一寻呼参数中第一偏移量、接口间无线帧偏差、和/或侧链寻呼时机是否与第二偏移量有关的配置方式，包括如下至少一种方式：
方式一：第一终端与第二终端建立侧行链路的连接时或者连接后，第二终端通过直接通信接口向第一终端发送配置消息，指示第一终端进行配置；
方式二：在第一终端的预配置信息中对第一偏移量的取值、接口间无线帧偏差的取值、和/或侧链寻呼时机是否与第二偏移量有关进行配置；
方式三：在通信协议的默认参数中配置第一偏移量的取值、接口间无线帧偏差的取值、和/或侧链寻呼时机是否与第二偏移量有关；
方式四：在通信协议中规定第一偏移量的取值、接口间无线帧偏差的取值、和/或侧链寻呼时机是否与第二偏移量有关。
基于该方式一，图6为本申请的另一实施例提供的寻呼方法的流程示意图。如图6所示，该方法包括：
S601、第一终端与第二终端建立侧行链路的连接。
S602、第二终端向第一终端发送第一消息，第一消息包括第一寻呼参数。
本步骤中，在第一终端与第二终端建立侧行链路的连接时或者之后，第二终端向第一终端发送第一消息，第一消息包括第一寻呼参数。其中，由于第一终端已知自身的标识，因此第一消息中的第一寻呼参数不包括第一终端的标识，第一寻呼参数中的剩余内容可参照前述实施例的相关内容。
其中，第一消息的消息形式例如为直接通信接口-直接通信链路层(简称PC5-S)的信令消息、直接通信接口-无线资源控制层(简称PC5-RRC)的信令消息、媒体接入控制层 (Media Access Control，MAC)中控制单元(Control Element，CE)的信令消息、或者下行控制链路(Downlink Control Information，DCI)的信令消息。
一示例中，第一消息还可用于指示侧链寻呼时机是否与第二偏移量是否有关。此时，第二终端可在网络设备针对空中接口配置的第二寻呼参数的基础上，增加第一偏移量、以及侧链寻呼时机是否与第二偏移量是否有关的指示。可选地，还可以增加接口间无线帧偏移。
具体的，若第一消息指示侧链寻呼时机与第二偏移量有关，则第二终端配置的第一寻呼参数包括第二偏移量；若第一消息指示侧链寻呼时机与第二偏移量无关，则第二终端配置的第一寻呼参数不包括第二偏移量，或者，第二终端配置的第一寻呼参数包括第二偏移量、但在第一寻呼参数中第二偏移量的取值为零。
又一示例中，第二终端可直接确定侧链寻呼时机与第二偏移量无关，通过第一消息发送给第一终端的第一寻呼参数中不包括第二偏移量，此时，无需通过第一消息向第一终端指示侧链寻呼时机是否与第二偏移量是否有关。
S603、第一终端根据第一寻呼参数，确定侧链寻呼时机，并按照侧链寻呼时机，在直接通信接口监听寻呼消息。
本步骤中，第一终端接收到第一消息后，根据第一消息中的第一寻呼参数，若第一消息中有侧链寻呼时机是否与第二偏移量是否有关的指示，还可根据该指示结合第一寻呼参数，确定侧链寻呼时机。并按照侧链寻呼时机，在直接通信接口监听寻呼消息。
其中，侧链寻呼时机的确定可参照前述实施例，不再赘述。
S604、第二终端确定空口寻呼时机，并按照空口寻呼时机，在空中接口监听网络设备寻呼第一终端的寻呼消息。
本步骤中，第二终端确定空口寻呼时机，也即确定对网络设备寻呼第一终端的寻呼消息进行监听的时机，并按照空口寻呼时机，在空中接口监听网络设备寻呼第一终端的寻呼消息。
一示例中，第二终端可根据第二寻呼参数，确定空口寻呼时机。其中。根据第二寻呼参数，确定空口寻呼时机，可参照前述实施例，不再赘述。
又一示例中，第二终端在确定空口寻呼时机之前，可接收第一终端发送的第二消息，第二消息包括空口寻呼时机和/或第一终端的标识。若第二消息包括空口寻呼时机，则第二终端可从第二消息中直接获得空口寻呼时机，而无需进行根据第二寻呼参数，确定空口寻呼时机。若第二消息包括第一终端的标识，则第二终端可以结合第一终端的标识和网络设备对空中接口配置的寻呼周期、寻呼周期中寻呼帧的数量、寻呼周期中的寻呼次数、第二偏移量，得到第二寻呼参数，进而根据第二寻呼参数，确定空口寻呼时机。
S605、第二终端接收到网络设备寻呼第一终端的寻呼消息。
本步骤中，第二终端按照确定的空口寻呼时机在进行网络设备寻呼第一终端的寻呼消息的监听的过程中，接收到网络设备寻呼第一终端的寻呼消息。
S606、第二终端根据第一寻呼参数，确定第一终端的侧链寻呼时机。
S607、第二终端按照侧链寻呼时机，将寻呼消息发送给第一终端。
本步骤中，第二终端根据第一寻呼参数，确定侧链寻呼时机的过程可参照前述实施例的描述，不再赘述。第二终端在接收到网络设备寻呼第一终端的寻呼消息之后，按照侧链 寻呼时机，将寻呼消息通过直接通信接口的一个或多个子信道发送给第一终端。
一示例中，若第二终端接收到第一终端发送的第二消息，第二消息包括空口寻呼时机和/或第一终端的标识，则第二终端可以根据空口寻呼时机和/或第一终端的标识，确定侧链寻呼时机。
其中，若第二消息包括空口寻呼时机，则第二终端可从第二消息中获得空口寻呼时机，并在空口寻呼时机的基础上增加第一偏移量，还可以增加接口间无线帧偏移，得到侧链寻呼时机。
其中，若第二消息包括第一终端的标识，则第二终端可以结合第一终端的标识和预先对直接通信接口配置的寻呼周期、寻呼周期中寻呼帧的数量、寻呼周期中的寻呼次数、第一偏移量等参数，得到第一寻呼参数，进而根据第一寻呼参数，确定侧链寻呼时机。
在一些实施例中，第二终端在接收到网络设备寻呼第一终端的寻呼消息之后，按照侧链寻呼时机，将寻呼消息通过直接通信接口中配置的一个或多个寻呼子信道发送给第一终端。因此，通过指定直接通信接口的部分子信道作为寻呼子信道，达到节约信道资源的目的，而且第一终端无需监听直接通信接口的所有子信道、第二终端也无需通过直接通信接口的所有子信道向第一终端发送寻呼消息，减小了终端的功耗。
在一些实施例中，第一消息还用于指示直接通信接口的多个子信道中的一个或多个寻呼子信道。其中，寻呼子信道用于传输寻呼消息。通过指定直接通信接口的部分子信道作为寻呼子信道，达到节约信道资源的目的，而且第一终端无需监听直接通信接口的所有子信道、第二终端也无需通过直接通信接口的所有子信道向第一终端发送寻呼消息，减小了终端的功耗。
具体的，第一终端在接收到第一消息后，可按照确定的侧链寻呼时机在直接通信接口的一个或多个寻呼子信道进行寻呼消息的监听。第二终端在接收到网络设备寻呼第一终端的寻呼消息后，可按照确定的侧链寻呼时机通过直接通信接口的一个或多个寻呼子信道发送寻呼消息。
在一些实施例中，第二终端通过直接通信接口发送给第一终端的寻呼消息中包括第一终端的标识，以便第一终端根据寻呼消息中终端的标识确定该寻呼消息是否为网络设备对第一终端的寻呼。
