摘要
基于多个重点城市的路测数据,系统分析了中国联通GSM网络语音编码模式、载波频段、语音质量、载干比、切换等多个因素对语音业务MOS质量的影响,并且对WCDMA网络语音业务MOS质量和信干比,以及HSDPA下载速率和CQI的关系分别做了统计分析,最后,针对统计分析中所发现的问题给出了网络优化的相关建议。
Based on driving test data from several key cities, the influence on MOS of GSM voice services by voice codec mode, carrier frequency, RxQual, C/I and handover is analyzed. The relationships between MOS of WCDMA voice services and Ec/lo, the HSDPA download speed and CQI are also provided. Finally, suggestions on network optimization are given in view of the problems arising from statistical analysis.
