Description

配置频率优先级的方法、终端设备、基站和核心网设备 技术领域
本申请涉及通信领域，并且更具体地，涉及一种配置频率优先级的方法、终端设备、基站和核心网设备。
背景技术
长期演进(Long Term Evolution，LTE)通信系统可以支持终端在不同频率的小区之间进行小区重选，以实现将终端分布到不同频点上驻留的功能，这样做的好处是使得各个频率的小区无线资源都能得到合理的利用。特别地，处于连接态的终端可以在释放连接前从网络获取频率优先级配置信息来支持进入空闲态之后的异频小区重选。
在5G新无线(New Radio，NR)通信系统中，引入了网络切片技术，不同的切片可能工作在不同的频率上。终端如果能够驻留在其所注册的并且最可能进行业务传输的切片所在的频率上，将能够避免终端在进入连接态后进行异频切换。同时，在5G系统中，终端设备可以处在连接态、空闲态(idle)和非激活态(inactive)，因此，异频的小区重选可能发生在空闲态或者非激活态的终端上。因此，对于异频小区重选来说，频率优先级配置不仅要考虑终端所注册的切片以及最可能发起业务连接的切片，同时也需要考虑非激活态的终端，因此，现有的LTE系统中支持异频的小区重选的频率优先级配置无法满足5G系统的需求。
