基于SA组网模式的语音策略研究及感知提升优化方法

Research on Voice Strategy Based on SA Networking Mode and Optimization Method of Perception Enhancement

目前5G网络已经部署VoNR,基站侧已经开通VoNR功能,但是大部分终端没有正式推出相关支持的软件版本,语音业务主要还是采用回落的方式,即EPS FB的方式承载到LTE。采用EPS FB的形式承载,EPS FB策略分为基于测量重定向的EPS FB、基于HO的EPS FB、及盲重定向的EPS FB等三种方式。以改善5G用户语音体验为导向,深度评估EPS FB执行情况,制定场景化的适配优化方案。根据SA LTE网络组网、建设进度、覆盖情况,研究EPS FB回落策略、精细化EPSFB相关参数,根据不同语音通话质量环境,制定相适应的策略保障语音回落快速。

At present,VoNR has been deployed in the 5G network,and the VoNR function has been enabled on the base station side.However,most terminals have not officially introduced the relevant supported software versions.The voice service is mainly carried to the LTE in the way of EPS FB.The EPS FB strategy is divided into three modes:measurement redirection based EPS FB,HO based EPS FB,and blind redirection EPS FB.Guided by improving the voice experience of 5G users,conduct in-depth evaluation of EPS FB implementation,and formulate a scenario based adaptation optimization scheme.According to SA LTE network networking,construction progress and coverage,study EPS FB fallback strategy and fine EPSFB related parameters,and formulate appropriate strategies to ensure rapid voice fallback according to different voice call quality environments.
