摘要:

5G网络语音解决方案目前有两种,分别为演进分组系统回落(evolution packet system falls back,EPS Fallback)和新空口承载语音(voice over new radio,VoNR)。在5G网络建设初期,5G基站覆盖和5G终端渗透率均不高,EPS Fallback作为5G语音过渡方案,目前随着2.6 GHz和700 MHz网络的部署,独立组网(standalone,SA)模式逐步实现独立组网,VoNR将作为5G语音的主要方案。为了积极应对VoNR的部署,多维度对比分析VoNR的优势,深入研究了VoNR特性功能、参数以及应用场景,制定了VoNR无线策略,针对上行弱场、干扰、大话务等各类场景下的特性功能部署和优化提供建议和方案,为 VoNR 正式商用做好准备。

Abstract:

There are two 5G voice solutions, EPS Fallback and VoNR.In the early stage of 5G network construction, 5G base station coverage rate and terminal penetration rate were not high, so EPS Fallback was used as a 5G voice transition solution.At present, with the deployment of 2.6 GHz and 700 MHz networks, the SA network achieves independent networking, and VoNR will be the main solution for 5G voice.In order to actively respond to the deployment of VoNR and analyze the advantages of VoNR from multiple dimensions, an in-depth research on VoNR features, parameters, and application scenarios were conducted, VoNR wireless strategy deployment was formulated, for uplink weak field, interference, large traffic characteristics of all kinds of scenarios functions such as deployment and optimization to provide suggestion and scheme, and prepares for VoNR’s official commercial use.

Key words: VoNR, 5G voice solution, interoperability strategy, 5G wireless network
