摘要：

随着LTE数据业务量的持续增长和VoLTE用户数的逐步增加，用户对业务的感知需求也越来越高，高铁专网优化面临诸多挑战。中国移动通信集团山东有限公司（以下简称山东移动）从高铁双层网部署、高铁VoLTE优化、公专网交界协同优化、新功能发掘部署4个维度，探索出一套契合高铁现网需求、可落地执行的解决方案。方案实施后，高铁专网测试VoLTE覆盖率从87.95%提升至91.66%,MOS值由3.6提升到4,MOS大于3.0的占比由89.61%提升到96.70%。

关键词: 高铁, LTE, VoLTE, 用户感知

Abstract:

With the development of LTE data and VoLTE services,subscribers pay more and more attention to network experience.LTE optimization faces many challenges.Therefore,China Mobile Shandong Corporation made a complete and feasibility solution,which met the requirement of high-speed scene optimization.There were four dimensions in this solution: double layers network deployment,VoLTE optimization of high-speed rail,coordinating optimization in the boundary of high-speed network and normal LTE network,and the exploration and deployment of new functions.After the implementation of the solution,VoLTE coverage rate increases from 87.95% to 91.66%,MOS value upgrades from 3.6 to 4,the ratio of MOS value greater than 3.0 rised from 89.61% to 96.70%.

Key words: high-speed rail, LTE, VoLTE, user perception
