摘　　要：自我国进入2G、3G、4G、5G多网共存以来,2G/3G制式在技术指标、资源占用、运维成本等方面的不足逐渐凸显,运营商急需加快2G/3G退网进程,将有限的资源投入到主流的4G/5G的发展中去。提出一种基于VoLTE终端渗透率和VoLTE承载业务占比2个指标预测退网时间的方法,根据站址空间数据进行计算并分析2G/3G站址周边覆盖情况,精准定位补盲区域,为运营商做好退网规划,推动退网进程提供参考。Since China entered the coexistence of 2G,3G,4G,and 5G,the 2G/3G system has gradually become deficient in technical indicators,resource occupation and operation and maintenance costs.The operator urgently needs to speed up the 2G/3G shutdown process and invests limited resources into the mainstream 4G/5G development.It proposes a method to predict the shutdown time based on the two indicators of VoLTE terminal penetration rate and VoLTE voice service proportion.The method calculates the spatial data of the station site to analyze the coverage around the 2G/3G site,accurately locates the blind area,and provides reference for operator to make the shutdown planning and promote the shutdown process.

关 键 词：2G/3G退网 VoLTE终端渗透率 VoLTE承载业务占比 空间计算
