摘要
为了解决5G语音在不同网络(2G/3G/4G/5G)切换过程中尽量保持连续的问题,介绍了5G NSA/SA不同架构下的5G语音连续性解决方案,包括NSA架构下4G到2G/3G的切换场景,SA架构下5G到4G以及5G到2G/3G的切换场景,以及切换后终端如何快速返回5G等,然后根据运营商现网的实际情况和5G的部署阶段,提出相应的5G语音及连续性方案部署和演进建议。
In order to solve the issue of maintaining the continuity of 5G voice during the handover of different networks(2G/3G/4G), this paper introduces the voice continuity solutions under different architectures of 5G NSA/SA, including the handover from 4G to 2G/3G in NSA architecture and the one from 5G to 4G, 5G to 3G in SA architecture, as well as how the terminal can quickly return to 5G after handover. Then, according to the actual situation of the operators’ current networks and the 5G deployment stage, the corresponding voice continuity solutions of 5G voice and evolution suggestions are provided.
