以下，简单说明与本申请实施例相关的小区重选测量准则和小区重选准则。
小区重选测量准则
小区测量可以包括同频测量和异频或异接入技术(Radio Access Technology，RAT)测量。
1、同频测量
具体地，UE可以通过广播消息获取同频测量相关的小区重选参数，例如同频测量启动门限，其中，同频测量启动门限包括同频参考信号接收功率(Reference Signal Receiving Power，RSRP)门限(即S intraserachP)和同频参考信号接收质量(Reference Signal Receiving Quality，RSRQ)门限(即S intraserachQ)。
UE可以根据服务小区的测量结果结合同频测量启动门限，确定是否启动同频测量。
例如，所述UE可以在服务小区的测量结果不满足同频测量启动门限时，不启动同频测量。否则，启动同频测量。
可选地，所述服务小区的测量结果不满足同频测量启动门限可以包括S rxlev＞S intraserachP，并且S qual＞S intraserachQ,否则，表示服务小区的测量结果满足同频测量启动门限。其中，S rxlev表示服务小区的RSRP相关测量结果，例如，S rxlev等于Qrxlevmeas-Qrxlevmin，其中，Qrxlevmeas表示服务小区的RSRP，Qrxlevmin例如可以为-128dBm，S qual表示服务小区的RSRQ相关测量结果，例如，S qual等于Qqualmeas-Qqualmin，其中，Qqualmeas表示服务小区的RSRQ，Qqualmin例如可以为-60。
2、异频和异RAT测量
具体地，可以通过广播消息获取异频或异RAT测量相关的小区重选参数，例如异频测量启动门限，其中，异频测量启动门限包括异频RSRP门限(即S nonintraserachP)和异频RSRQ门限(即S nonintraserachQ)。
UE可以根据服务小区的测量结果，频点的重选优先级结合异频测量启动门限，确定是否启动异频或异RAT测量。
例如，对于重选优先级高于当前频点的重选优先级的异频频点或异RAT频点，总是执行测量。
又例如，对于重选优先级低于或等于当前频点的重选优先级的异频频点或异RAT频点，按照如下规则进行测量：
若服务小区的测量结果不满足异频测量启动门限时，不启动异频或异RAT测量。否则，启动异频或异RAT测量。
可选地，所述服务小区的测量结果不满足异频测量启动门限可以包括S rxlev＞S nonintraserachP，并且S qual＞S nonintraserachQ,否则，表示所述服务小区的测量结果满足异频测量启动门限。其中，S rxlev表示服务小区的RSRP相关测量结果，例如，S rxlev等于Qrxlevmeas-Qrxlevmin，其中，Qrxlevmeas表示服务小区的RSRP，Qrxlevmin例如可以为-128dBm，S qual表示服务小区的RSRQ相关测量结果，例如，S qual等于Qqualmeas-Qqualmin，其中，Qqualmeas表示服务小区的RSRQ，Qqualmin例如可以为-60。
小区重选准则
如果高优先级小区上有多个邻小区满足条件，则选择高优先级频点上的最优小区，对于同等优先级的频点，可以根据同频小区重选的R准则进行小区重选。
例如，对于高优先级小区的小区重选，需要满足如下条件：
1、UE驻留原小区时间超过一定时间，例如，1s；
2、若广播了第一门限(例如，Thresh X，HighQ，或称高优先级重选门限)，高优先级频点的小区的S值(例如，Squal)大于第一门限(Thresh X，HighQ)；或者，若未广播Thresh X，HighQ，高优先级频点的小区的S值(例如，Srxlev)大于第二门限(Thresh X，HighP)；
3、高优先级频点上的小区的S值的持续时间超过重选时间参数(例如，Treselection RAT)。
又例如，对于低优先级频点的小区重选，需满足如下条件：
1、UE驻留服务小区的时间超过一定时间，例如1s；
2、没有高优先级(或同等优先级)频点的小区符合重选要求条件；
3、若广播了第三门限(例如，Thresh Serving,LowQ，或称服务频点低优先级重选门限)，服务小区的S值(例如，Squal)小于所述第三门限，并且低优先级频点上的小区的S值大于第四门限(例如Thresh x,LowQ，或称低优先级重选门限)；或者，若未广播Thresh Serving,LowQ，服务小区的S值(例如，Srxlev)小于第五门限(例如，Thresh Serving,LowP)，并且低优先级频率小区的S值(例如，Srxlev)大于第六门限(例如，Thresh x,LowP)。
4、低优先级频点小区的S值的持续时间超过重选时间参数(例如，Treselection RAT)。
应理解，以上示例的小区重选测量准则和小区重选准则仅为示例，随着通信技术的演进和发展，也可以对其进行修改或调整，本申请并不限于此。
由此可见，在小区重选中，主要将小区的信号质量作为判断条件，基于此重选的小区为信号质量好的小区，但是在引入网络切片之后，不同的小区可能支持不同的网络切片，终端设备传输的业务可能需要小区支持特定的网络切片，此情况下，只考虑小区的信号质量进行小区重选，可能重选到一个不支持终端需要的网络切片业务的小区，影响终端的业务传输。
