摘　　要：Vo LTE语音质量优化是当前优化工作的重点内容,但分析优化手段相对较为欠缺,问题定位精度也较低,无法满足当前优化工作所需。通过对"基站拟合MOS评分"和Vo LTE用户"呼叫记录"两项新技术的研究和应用,探索发现了一种新的语音质量问题的定位分析方法。该方法以"基站拟合MOS评分"为问题发现手段,以呼叫记录为问题定位基础,同时结合MR、话统、基站工程参数、基站性能参数、告警和操作记录等数据,通过多维数据分析,实现了语音质量准通话级的问题定位,定位全面性、实时性和精准度相对传统优化手段都有较大的提升。VoLTE voice quality optimization is the important content optimization,but relatively lack.Because the problem analysis and optimization methods positioning precision is low and cannot meet the required by the current optimization.We explored a new method to position the problem of voice quality by fi tting“basestation MOS scores”and VoLTE“Call history Information”.This method which based on MOS scores,realized the problem of voice quality quasi-call level.This method is based on the call logs which combined with the MR,traffi c statistics,and base station engineering parameters,the performance of the base station parameters,alarms,and operation records data,for problem location and data analysis.It has a greate improvement compared with the traditional way of optimization in positioning comprehensive,real-time and precision.
