高速移动列车无线组网方案

为满足快速增长的旅客运输需求，国家“十一五”规划了“四纵四横”铁路快速客运通道以及3个城际快速客运系统，时速高达380 km/h。随着列车时速的不断加快，车厢内手机用户通信时发生切换混乱、接通率低和掉话等现象，无线网络覆盖面临挑战。文章立足于高铁专网设计总体目标，基于高速移动通信性能影响因素，采用分布式基站和一体化基站，提出一种高速铁路组网方案。

Solution for High-Speed Railway Construction

In order to meet growing passenger needs for public transportation,a four vertical and four horizontal railway passenger system ,as well as a three fast trains inter-city express system (with top speeds of 380km/h) has been proposed in the Eleventh Five-Year plan. However,with the increased top speeds of these modern trains ,wireless coverage within them faces particular challenges. These include soft switching confusion of mobile phone users ,low throughput rate ,and call dropout. This paper presents some ...
