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%。
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%.
