铁路大提速后,原有的无线网络覆盖已经不能满足提速后车厢内用户的覆盖需求,立足于高铁专网设计总体目标,重点解决铁路提速后车厢内手机用户通信时发生的切换混乱、接通率低和掉话等现象,提出了高速铁路组网方案,为基站位置和天线放置位置的正确选择提供了依据;同时通过建立行驶列车中乘客的话务模型和数据业务模型,提出了各专网小区的载频配置原则。
After the railway speeding up, the original wireless network coverage can not meet the coverage needs of users within the speed-raised trunk. Based on the overall goal of designing the high-speed rail private network, the focus is to solve the problem of chaos in handover when the mobile phone users within the speed-raising railway are communicating, Low rate and dropped calls and other phenomena, proposed high-speed railway network program for the base station location and antenna placement provides the basis for the correct choice; at the same time by establishing the train traffic in the passenger traffic model and data service model, put forward the various Network cell carrier frequency configuration principle.
