双卡双待是指一个终端设备可以同时拥有两张用户身份识别模块(subscriber identification module，SIM)卡，两个SIM卡都可以正常工作的技术。其中，上述两个SIM卡可以属于同一运营商或者不同运营商。例如，SIM卡1和SIM卡2可同时属于中国移动运营商，或者，SIM卡1可属于中国移动运营商，SIM卡2可属于中国联通运营商。上述两个SIM卡还可以属于同一通信制式，或不同的通信制式。例如，SIM卡1和SIM卡2可同时属于新无线接入技术(new RAT，radio access technology，NR)，或者，SIM卡1可属于长期演进(long term evolution，LTE)，SIM卡2可属于NR等。
四、寻呼时机(paging occasion，PO)
为了节省电量，终端设备可进入空态(idle)态和非活跃(inactive)态，进行休眠。终端设备可按照一定的周期，在设定的时间单元唤醒自己，监听网络设备是否寻呼自己。如果监听到网络设备寻呼自己，则终端设备切换到活跃态，否则，继续保持当前状态。上述终端设备监听寻呼的时间单元可称为寻呼时机(paging occasion，PO)。
五、终端设备标识
终端设备标识可为网络设备为终端设备分配的标识。对于单卡单待的终端设备，例如单卡单待终端设备可以被配置使用SIM卡1，则终端设备的标识可为对应SIM卡1的标识。对于双卡双待的终端设备，例如双卡双待终端设备可以被配置使用SIM卡1和SIM卡2，则终端设备的标识可指对应于SIM卡1的标识，或者，对应于SIM卡2的标识。本申请实施例中的SIM卡，可为实体SIM卡，或虚拟SIM卡等，不作限定。

在本申请实施例中，终端设备可根据第一初始标识，可确定第一PO，或者，还可描述为，第一初始标识对应于第一PO。根据第二初始标识，可确定第二PO，或者，还可描述为，第二初始标识对应于第二PO。关于如何根据初始标识，确定PO，将在以下实施例中具体介绍。

需要说明的是，图2流程所示的方法，可应用于双卡双待的场景中，或者可应用于其他场景中，并不作限定。例如，图2流程所示的方法，还可应用于：针对一个终端设备，网络侧为该终端设备仅分配一个UE-ID的场景，即单卡单待的场景等。
示例的，当图2流程所示的方法，应用于双卡双待的场景时，所述终端设备可为双卡双待模式，所述终端设备可以被配置使用第一SIM卡和第二SIM卡，所述SIM卡可为虚拟SIM卡或实体SIM卡。网络设备可为终端设备分配两个UE-ID，分别为对应于第一SIM卡的UE-ID和对应于第二SIM卡的UE-ID。所述对应于第一SIM卡的UE-ID，可具体为网络设备为第一SIM卡分配的UE-ID。所述对应于第二SIM卡的UE-ID，可具体为网络设备为第二SIM卡分配的UE-ID等。在本申请实施例中，可调整对应于第一SIM卡的UE-ID或调整对应于第二SIM卡的UE-ID。当采用图2所示流程中的方法，用于调整对应于第一SIM卡的UE-ID时，上述图2所示流程中的终端设备的第一初始标识可为调整前对应于第一SIM卡的UE-ID，所述终端设备的第一更新标识可为调整后对应于第一SIM卡的UE-ID。当采用图2所示流程中的方法，用于调整对应于第二SIM卡的UE-ID时，上述图2所示流程中的终端设备的第一初始标识可为调整前对应于第二SIM卡的UE-ID，所述终端设备的第一更新标识可为调整后对应于第二SIM卡的UE-ID。

示例一
在本申请实施例中，当终端设备的模式为单发单收，且第一PO的时域位置与第二PO的时域位置部分重叠或完全重叠时，终端设备可确定需要调整第一PO的时域位置。通过上述图2所示流程的调整，可使第一PO与第二PO的时域位置完全不重叠。
示例的，在本申请实施例中，第一PO可对应于第一通信网络，第二PO可对应于第二通信网络，第一通信网络与第二通信网络的通信制式相同或不同。所述通信网络可采用3G、LTE、NR、或者甚至未来的6G等制式。所述第一通信网络与第二通信网络相同，可指两者采用的通信制式相同且运营商相同。所述第一通信网络与第二通信网络不同，可指两者采用的通信制式不同或者运营商不同等。
示例的，以终端设备采用双卡双待模式，且终端设备侧被配置使用第一SIM卡和第二SIM卡为例，详细说明上述过程。
通常，针对双卡双待终端设备，根据终端设备的收发能力不同，可将终端设备分为以下三类：双收双发(dual Rx/Tx，transport/receive)终端、双收单发(dual Rx/single Tx)和单收单发(single Rx/single Tx)终端。
其中，双收双发终端：指终端设备可同时接收和发送上述两个SIM卡的数据。双收单发终端：指终端设备可同时接收上述两个SIM卡中的数据，但在一个特定时间单元，终端设备仅能发送一个SIM卡中的数据。单收单发终端：指在一个特定时间单元，终端设备只能收/发上述两个SIM卡中一个SIM卡的数据。
同时，为了节省电量，终端设备可进入空态(idle)态和非活跃(inactive)态，进行休眠。终端设备可按照一定的周期，在设定的时域位置唤醒自己，监听网络设备是否寻呼自己。如果监听到网络设备的寻呼，则终端设备切换到活跃态，否则，继续保持当前状态。上述终端设备唤醒自己的时域位置可称为寻呼时机(paging occasion，PO)。
通过上述分析可知，对于上述单收单发模式的终端，在一个特定时域位置，终端设备仅能接收对应一个SIM卡中的数据。如果两个SIM卡的PO位置相重叠，那么终端设备在PO位置所对应的时间单元，仅能监听一个SIM卡对应的网络设备是否寻呼自己，可能会导致另一个SIM卡的信息被漏听。因此，在本申请实施例中，对于单发单收的终端，当第一PO位置和第二PO位置完全重叠或部分重叠时，需要调整第一PO的时域位置。
比如，如图3所示，一个寻呼帧(paging frame，PF)包括10个子帧，索引依次为0至9。第一SIM卡采用NR通信制式，第二SIM卡采用LTE通信制式，且第一SIM卡与第二SIM卡间存在三个子帧的时间偏移(timing offset)。第一SIM卡所对应的第一PO的时域位置为第一PF中索引为7的子帧，第二SIM卡所对应的第二PO的时域位置为第二个PF中索引为0的子帧。通过图3可以看出，第一PO的时域位置和第二PO的时域位置完全重叠。此时，可对第二SIM卡所对应的第二PO的时域位置进行调整，比如，可将第二SIM卡所对应的第二PO的时域位置调整至第三PF中索引为5的子帧。采用上述方式，对于单收单发终端，可在第一个PF中索引为7的子帧上，监听SIM卡1的寻呼消息，在第三PF中索引为5的子帧上，监听SIM卡2的寻呼消息，避免漏听SIM卡的信息。
可以理解的是，在图3所示的示例中，是以第一PO的时域位置和第二PO的时域位置，完全重叠为例进行说明的。第一PO的时域位置和第二PO的时域位置部分重叠，调节的过程与上述过程相类似，不再举例说明。
示例二
在本申请实施例中，当终端设备的模式为双发双收，且第一PO的时域位置与第二PO的时域位置部分重叠或者完全不重叠时，终端设备可确定需要调整第一PO的时域位置。采用上述图2所示流程中的方法，可使得第一PO的时域位置与第二PO的时域位置完全重叠。
在本申请实施例中，以终端设备被配置使用第一SIM卡和第二SIM卡，且终端设备采用双收双发模式为例，说明上述过程。
示例的，对于上述双收双发终端，当两个SIM卡为同一运营商且同一制式时，上述两个SIM卡很可能驻留在同一个小区。如果网络设备的PO位置不重叠，网络设备需要在多个PO位置监听网络设备的寻呼消息，导致电量浪费。因此，在本申请实施例中，对于双发双收模式的终端设备，在两个PO位置部分重叠或完全不重叠时，需要将两个PO位置调整为完全重叠，从而降低终端设备的监听功耗。比如，在本申请实施例中，第一SIM卡的网络设备为网络设备1，对应于第一SIM卡的PO位置为位置1，第二SIM卡的网络设备为网络设备2，对应于第二SIM卡的PO位置为位置2。在一示例中，终端设备可按照一定的周期在PO位置1，唤醒自己，监听网络设备1是否寻呼自己。终端设备按照一定的周期在PO位置2，唤醒自己，监听网络设备2是否寻呼自己。但当两个SIM卡驻留在同一个小区时，两个SIM卡所对应的网络设备是相同的，即上述网络设备1与网络设备2是同一个网络设备。终端设备再按照上述方式，唤醒自己是没有必要的，浪费电量。本申请实施例的改进之处在于，当终端设备的两个SIM卡驻留在同一个小区时，可将对应于SIM卡1的PO位置与对应于SIM卡2的PO位置调整为完全重叠，节省电量。
如图4所示，第一SIM卡和第二SIM卡接入同一小区(access to same cell)，对应于第一SIM卡的第一PO位置为第一个PF中索引为7的子帧，对应于第二SIM卡的第二PO位置为第三个PF中索引为5的子帧。可以看出，对应于第一SIM卡的第一PO位置和对应于第二SIM卡的第二PO位置完全不重叠。示例性的，如图4所示，可将对应于第一SIM的第一PO位置，调整至第一PF中的子帧7，对应于第一SIM卡的第一PO位置与对应于第二SIM卡的第二PO位置完全重叠，从而终端设备在第一个PF中索引为7的子帧上，同时监听第一SIM卡和第二SIM卡的寻呼消息，节省电量。
需要说明的是，上述示例一和示例二仅为示例性说明，并不作为对本申请的限定，比如，本申请实施例提供的方案，还可应用于除上述示例一和示例二外，其它需要调整PO位置的场景中。
如图5所示，本申请实施例还提供一种通信方法的流程，在该流程中，终端设备被配置使用第一SIM卡和第二SIM卡。利用图5所示的流程可对上述示例一和示例二所述场景中的终端设备标识进行调整。该流程可包括：
S501.终端设备确定对应于第一SIM卡的PO时域位置和对应于第二SIM卡的PO时域位置是否存在冲突。如果存在冲突，则执行S502，否则结束流程。
在本申请实施例中，终端设备可获取对应于第一SIM卡的初始UE-ID和对应于第二SIM卡的初始UE-ID，所述初始UE-ID还可称为调整前UE-ID；根据对应于第一SIM卡的初始UE-ID，确定对应于第一SIM卡的PO时域位置；根据对应于第二SIM卡的初始UE-ID，确定对应于第二SIM卡的PO时域位置。其中，在上述示例一的场景中，对应于所述第一SIM卡的PO时域位置和对应于第二SIM卡的PO时域位置冲突，可指对应于第一SIM卡 的PO时域位置和对应于第二SIM卡的PO时域位置完全重叠或部分重叠。在上述示例二的场景中，所述对应于第一SIM卡的PO时域位置和对应于第二SIM卡的PO时域位置冲突，可指对应于第一SIM卡的PO时域位置和对应于第二SIM卡的PO时域位置部分重叠或完全不重叠。
S502.终端设备向核心网设备发送第一消息，所述第一消息中包括第一偏移，或，所述第一消息中包括对应于第二SIM卡的更新UE-ID，第一偏移可指对应于第二SIM卡的初始UE-ID与对应于第二SIM卡的更新UE-ID两者之间的偏移。示例的，所述核心网设备可为接入和移动性管理功能(access and mobility management function，AMF)实体。
需要说明的是，在本申请实施例中，第一SIM卡对应的接入网设备和第二SIM卡对应的接入网设备可相同或不同，第一SIM卡对应的核心网设备和第二SIM卡对应的核心网设备可相同或不同。在上述S502中，终端设备可向第一SIM卡对应的核心网设备发送第一消息。相应的，下述S503中，第一SIM卡对应的核心网设备向终端设备发送第一回复消息。或者，在上述S502中，终端设备可向第二SIM卡对应的核心网设备发送第一消息。相应的，下述S503中，第一SIM卡对应的核心网设备向终端设备发送第一回复消息。第一SIM卡对应的核心网设备与第二SIM卡对应的核心网设备可为同一网络设备，或者可为不同的网络设备，不作限定。
S503.核心网设备向终端设备发送第一回复消息，所述第一回复消息可用于指示核心网设备同意/接受终端设备的所述第一偏移或对应于第二SIM卡的更新UE-ID的申请，即核心网设备同意终端设备的申请。或者，核心网设备可不同意终端设备的申请，为第二SIM卡重新分配一标识，该重新分配的标识可称为对应于第二SIM卡的建议UE-ID，对应于所述第二SIM卡的建议UE-ID可携带在第一回复消息中。
示例的，在本申请实施例中，第一消息可为第二SIM卡的注册消息，第一回复消息可为第二SIM卡的注册响应消息。或者，第一消息可为跟踪区更新(tracking area update，TAU)消息，第一回复消息可为TAU响应消息等。
S504.终端设备根据第一回复消息，重新计算对应于第二SIM卡的PO位置。
在本申请实施例中，若第一回复消息用于指示核心网设备接受终端设备的申请，则终端设备可根据上述第一消息中携带的第一偏移或对应于第二SIM卡的更新UE-ID，重新计算对应于第二SIM卡的PO位置。若第一回复消息中携带有对应于第二SIM卡的建议UE-ID，则终端设备根据所述第一回复消息中携带的对应于第二SIM卡的建议UE-ID，重新计算对应于第二SIM卡的PO位置。
其中，重新计算后的对应于第二SIM卡的PO位置与对应于第一SIM卡的PO位置不冲突。即在上述示例一的场景中，对应于第一SIM卡的PO位置与重新计算后对应于第二SIM卡的PO位置完全不重叠。在上述示例二的场景中，对应于第一SIM卡的PO位置与重新计算后对应于第二SIM卡的PO位置完全重叠。
在本申请实施例中，终端设备根据对应于第二SIM卡的更新UE-ID，或建议UE-ID，重新计算对应于第二SIM卡PO位置的过程，可参见下述公式1.1和公式1.2中的记载。关于终端设备根据第一偏移，重新计算对应于第二SIM卡PO位置的过程，可如下：
第一种情况，终端设备可根据第一偏移和对应于第二SIM卡的初始UE-ID，确定对应于第二SIM卡的更新UE-ID；终端设备可根据对应于第二SIM卡的更新UE-ID，重新计算对应于第二SIM卡的PO位置。
示例的，终端设备可根据下述公式1.1和公式1.2，重新计算对应于第二SIM卡的PO位置。比如，在下述公式1.1和公式1.2中的“UE-ID”参数采用“第一偏移+对应于第二SIM卡的初始UE-ID”的形式，也可以采用“对应于第二SIM卡的更新UE-ID”的形式。
第二种情况，终端设备可利用第二SIM卡的初始UE-ID，初步计算第二SIM卡的PO位置。然后利用第一偏移，对初步得到的第二SIM卡PO位置进行调整，得到最终的第二SIM卡PO位置。
示例的，终端设备可根据下述公式1.1和公式1.2，初步计算对应于第二SIM卡的PO位置。比如，在下述公式1.1和公式1.2中的“UE-ID”参数采用对应于第二SIM卡的初始UE-ID。
第三种情况，终端设备可同时利用对应于第二SIM卡的初始UE-ID和第一偏移，重新计算对应于第二SIM卡的PO位置。
示例的，终端设备可利用第一偏移，对下述公式1.1和1.2中，除UE-ID外的其它参数进行调整，得到对应于第二SIM卡的PO位置。比如，在下述公式1.1和公式1.2中的“UE-ID”参数采用对应于第二SIM卡的初始UE-ID，所述第一偏值可对下述公式1.1和公式1.2中，除“UE-ID”外的其它参数进行调整。例如，所述其它参数可为PF_offset和SFN等。
可选的，在图5所示的流程中，还可包括：S505.核心网设备向接入网设备发送第一指示，所述第一指示中包括上述第一偏移、上述对应于第二SIM卡的更新UE-ID或上述对应于第二SIM卡的建议UE-ID等。
示例的，在本申请实施例中，对终端设备的寻呼可分为两类：由核心网设备发起的对终端设备的寻呼，比如，对空闲(idle)态终端设备的寻呼等，以及，由接入网设备发起的对终端设备的寻呼，比如，对非活跃(inactive)态终端设备的寻呼等。在本申请实施例中，针对对应于第二SIM卡的寻呼，若该寻呼由核心网设备发起，则寻呼消息中包括对应于第二SIM卡的更新UE-ID或上述对应于第二SIM卡的建议UE-ID。若该寻呼由接入网设备发起，则寻呼消息中也需包括对应于第二SIM卡的更新UE-ID或上述对应于第二SIM卡的建议UE-ID。因此，在本申请实施例中，在上述S505的步骤中，核心网设备需要把上述第一偏移、对应于第二SIM卡的更新UE-ID或上述对应于第二SIM卡的建议UE-ID，通知接入网设备，且在由所述接入网设备发起对终端设备的寻呼时，所述接入网设备需要将上述第一偏移、对应于第二SIM卡的更新UE-ID或上述对应于第二SIM卡的建议UE-ID通知给一定区域内的其他接入网设备。
由上可见，在本申请实施例中，通过调整对应于第二SIM卡的UE-ID，可灵活调整对应于第二SIM卡的PO位置，避免对应于第一SIM卡的PO位置与对应于第二SIM卡的PO位置冲突，漏听对应于某一SIM卡的寻呼消息。
示例的，在本申请实施例，终端设备根据对应于第一SIM卡的UE-ID，或对应于第二SIM卡的UE-ID，计算PO位置的过程，可包括：
1、通过以下公式1.1，计算PO位置所对应的寻呼帧PF。
(SFN+PF_offset)mod T＝(T div N)*(UE_ID mod N)；公式1.1
其中，SFN表示寻呼帧PF的帧号，PF_offest表示寻呼帧PF的偏移量，T表示终端设备的寻呼周期，T的单位可为帧，N表示一个寻呼周期内PF的个数，UE-ID为终端设备的S-TMSI或IMSI模1024后的取值，所述PF_offset以及N的值均来自当前小区的广播。可 以理解的是，当上述公式1.1用于计算对应于第一SIM卡的PO位置时，上述公式1.1中的UE-ID具体为对应于第一SIM卡的S-TMSI或IMSI模1024后的取值。当上述公式1.1用于计算对应于第二SIM卡的PO位置时，上述公式1.1中的UE-ID具体为对应于第二SIM卡的S-TMSI或IMSI模1024后的取值等。
2、在确定寻呼帧PF之后，确定PO的位置；
通过以下公式1.2，计算PO的编号；根据PO的编号找到PO的位置，在获取PO的位置后，根据当前小区的寻呼的搜索空间的配置，即可找到UE的PO的配置。
i_s＝floor(UE_ID/N)mod Ns；公式1.2
其中，i_s表示PO的编号，Ns表示一个寻呼帧PF内PO的个数，Ns的值可来自于当前小区的广播。
通过上述记载可知，决定UE的PO位置的参数除了UE-ID外，其它参数均来自于当前小区，即其它参数是当前小区下所有UE所共有的参数。UE-ID的不同可导至不同UE的PO位置不同。
如图6所示，本申请实施例还提供一种通信方法的流程，在该流程中终端设备被配置使用第一SIM卡和第二SIM卡。利用图6所示的流程，可对上述示例二所述场景中，终端设备的初始标识进行调整。该流程可包括：
