摘要

VoLTE是LTE网络语音解决终极方案

而分组丢失率又是VoLTE的关键指标之一。分组丢失率高会导致语音卡顿、吞字、断续和单通等

严重影响用户的感知体验。本文从上行信噪比与VoLTE分组丢失率之间关系进行分析研究

分场景提出优化方案并展示优化效果。

Abstract

VoLTE is the ultimate voice solution for LTE network

and packet loss rate is one of the key indicators of VoLTE. High packet loss rate will lead to voice carton

swallowing words

intermittent

single-pass and so on

seriously affecting the user’s perception and experience. In this paper

the relationship between uplink SNR and VoLTE packet loss rate is analyzed

and the optimization scheme is proposed in different scenarios and the optimization effect is demonstrated.
