摘　　要：针对5G网络优化工作中出现的新空口承载语音(Voice over New Radio,VoNR)用户感知差的问题,探讨平均意见评分(Mean Opinion Score,MOS)值影响因素与分析流程,对后续出现的此类问题提供分析思路及具体解决方案。通过对网络现有参数和物理参数的核查,修改网络异常参数,以射频优化为基础、以参数优化为辅助,达到快速提升5G VoNR语音用户使用感知的目的。通过采用相应的网络优化手段,有效提升5G网络VoNR接通率,降低5G网络VoNR掉话率。Aiming at the problem of poor user perception of Voice over New Radio(VoNR)in the optimization of 5G network,this paper discusses the influencing factors and analysis process of Mean Opinion Score(MOS)value,and provides analysis ideas and specific solutions for such problems in the future.By checking the existing parameters and physical parameters of the network,the abnormal parameters of the network are modified.Based on radio frequency optimization and assisted by parameter optimization,the purpose of rapidly improving the usage perception of 5G VoNR voice users is achieved.By adopting the corresponding network optimization means,the VoNR connection rate of the 5G network is effectively improved,and the VoNR dropped call rate of the 5G network is reduced.
