建设GSM专网解决高铁用户话音感知的探讨

Research on method to improve the high-speed railway users' calling perception by constructing GSM special network

在传统宏基站覆盖模型下,高铁列车内用户话音呼叫的连续性和可靠性无法满足,根据专网特性规划建设高铁GSM专网,采用分布式基站合并小区方式组网方式,并通过单站和全网性能优化大幅度高铁用户通过可靠性和连续性,提高客户话音感知。同时,将高铁站点维护列入VIP维护级别,确保专网站点正常运行。

Under the traditional model of macro base station, continuity and reliability of the high-speed railway users calls can not be met. According to the high-speed railway network features, we desire and construct special GSM network, using combined cell technology with distributed base station .After the project is complete, we begin the single station and the whole network optimization to improve the high-speed railway users’ calling perception. Meanwhile, the high-speed rail maintenance site has been set up to the VIP level, to ensure the normal operation of specialized web sites.
