多卡终端的一个特点是可以在多个网络同时驻留，但是不同多卡终端的实现方式不同，有的多卡终端可以在多个网络同时发送和接收互不影响。而有的多卡终端可以在多个网络同时驻留但是可能采用时分的方式在两个网络驻留，也就是一段时间在网络A驻留听网络A的paging，一段时间在网络B驻留听网络B的paging；或者一段时间在网络A处于连接态收发数据，而一段时间要到网络B接收paging；或者一段时间在网络A收发数据，而一段时间要到网络B上建立连接进行数据的收发。
多卡终端在网络A处于连接态，可能会离开网络A切换到网络B执行某些业务。当多卡终端准备从网络A切换到网络B时，可向网络A发送离开通知，使得网络A收到多卡终端发送的离开通知后，可以避免在这段时间内调度或寻呼多卡终端，从而节省网络资源。
目前，多卡终端返回网络时如何通知网络尚不明确，这样可能会使得UE无法通知网络侧UE已返回网络，从而导致UE一直无法接收或发送数据，或者在某些条件下UE发送不必要的通知，浪费网络资源。

一些实施例中，判断是否向网络发送返回通知，包括：
在满足预设条件时，判断向所述网络发送所述返回通知，所述预设条件包括以下至少一项：
第一预设条件：所述终端返回所述网络时没有待发送的上行数据和/或信令；
其中，所述第一预设条件为基于以下至少一项确定：
所述终端的MAC层的指示、所述终端的无线资源控制(Radio Resource Control，RRC)层的指示、所述终端的服务数据适配协议(Service Data  Adaptation Protocol，SDAP)层的指示、所述终端的(Packet Data Convergence Protocol，PDCP)层的指示、所述终端的物理层(Physical，PHY)的指示。可以理解的是，所述终端的不同协议层之间还可以存在请求和响应过程。例如，所述终端的RRC层请求所述终端的MAC层指示所述终端当前是否有待发送的上行数据或信令(例如，缓存中有数据)。在有上行数据或信令要发送的情况下，所述终端的MAC层向RRC层发送指示信息。一种实施方式中，所述终端返回网络时，恢复或者重启所述终端的SDAP、PDCP、RRC、MAC、PHY中至少之一，在恢复或重启后，产生了新的上行数据。
第二预设条件：所述终端返回所述网络时没有缓存状态报告(Buffer Status Report，BSR)被触发；

其中，发送所述上行数据的资源包括配置授权(configured grant)或动态的授权(dynamic grant)。例如，UE离开网络前触发过BSR，网络可以基于BSR为UE分配一定的传输资源，之后由于UE离开网络，网络决定将所配置的传输资源暂时挂起，即UE无法使用这些资源进行传输，当UE返回网络后，这些资源仍处于挂起状态，而UE此时可能因为不满足BSR的触发条件而无法触发BSR，从而无法恢复被挂起的传输资源，在这种情况下，UE应该向网络侧发送返回通知。
第五预设条件：所述网络配置所述终端发送返回通知；
第六预设条件：所述终端返回所述网络前，根据所述网络的第一指示信息离开所述网络：一种实施方式为，所述终端离开网络前，向网络侧发送离开请求，网络侧收到后发送第一指示信息，第一指示信息可以用于响应所述 离开请求、或配置终端在返回网络时所需的资源。
第七预设条件：所述终端自主离开所述网络。
