降低上行丢包率提升VoLTE语音质量的研究

Research on Reducing Uplink Packet Loss Rate and Improving the Quality of VoLTE Speech

随着VoLTE用户数和业务量进入快速增长期,更好地提升VoLTE用户感知,更加准确地定位全网VoLTE语音感知差点显得尤为重要。论文通过阐述上行增强技术,对提升高丢包指标的相关参数进行分析研究,提出通过差异化设置上行语音目标BLER参数,找出满足网络需求的参数设置,优化降低VoLTE上行高丢包率,提出一种能改善上行丢包率及语音质量的有效方法。

With the rapid growth of VoLTE users and business volume, it is particularly important to better improve VoLTE user perception and more accurately locate VoLTE voice perception in the whole network. This paper describes uplinking enhancement technology, analyzes and studies the relevant parameters to improve the index of high packet loss, and puts forward an effective method to improve the uplinking packet loss rate and speech quality by setting the uplinking speech target BLER parameters by differentiation, to find out the parameter settings that meet the network requirements, and to optimize and reduce the high packet loss rate of VoLTE uplinking.
