摘要

语音一直是用户最基本、最原始的通信需求。目前有两种5G网络语音解决方案，EPS Fallback和VoNR。由于目前还处于5G网络建设的早期阶段，5G基站的覆盖率和5G终端的普及率都不高，因此EPS退调是5G语音演进道路上的过渡解决方案。随着5G SA网络的逐步演进和成熟，VoNR将成为5G语音的主要解决方案。本文介绍了5G语音业务的两种解决方案，研究了5G SA架构的语音连续性，并基于现场测试，对VoNR语音业务向VoLTe切换的场景进行了深入分析。

Research on 5G Voice Solutions and Continuity Analysis

Voice has always been the most basic and primitive communication requirement of users. There are currently two 5G network voice solutions, EPS Fallback and VoNR. Since it is still in the early stage of 5G network construction, the coverage of 5G base stations and the penetration rate of 5G terminals are not high, so EPS Fallback is a transitional solution on the road to 5G voice evolution. With the gradual evolution and maturity of 5G SA networks, VoNR will be the main solution for 5G voice. This paper introduces two solutions for 5G voice services, studies the voice continuity for 5G SA architecture, and conducts an in-depth analysis of the scenarios in which VoNR voice services are handover to VoLTe based on field tests.
