本申请涉及通信领域,尤其涉及用于建立连接的方法、网络设备和终端设备。
在5G部署初期,网络可能不能支持新空口语音承载(Voice over New Radio,VoNR),或者在网络拥塞的情况下,5G网络需要触发5G->4G的回落(Handover)流程,让4G网络执行长期演进语音承载(Voice over Long-Term Evolution,VoLTE),从而完成用户设备(User Equipment,UE)对语音建立的请求。对于5G->4G的Handover流程,通常包括两种:一种为5G的核心网不变,在UE需要执行语音时触发无线接入技术(Radio Access Technologies,RAT)回落,RAT接入从新无线(New Radio,NR)变为长期演进(Long Term Evolution,LTE),然后执行VoLTE操作;另一种为5G核心网切换到4G核心网,同时RAT也将由NR变为LTE,然后执行VoLTE操作。
但是在完成VoLTE语音后,对于专门为了建立语音而进行5G->4G回落的UE,目前还没有能够触发其执行快速返回5G网络的机制。
