上行信噪比对VoLTE分组丢失影响及分场景优化
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.
