摘要
解决地铁乘客的高质量移动通信问题,是现代地铁的重要研究课题之一。地铁系统是一个封闭环境,地铁无线通信系统中信号较为强烈,但由于地铁处于运动之中,数据的切换和链接成为影响用户通信质量的关键技术。从数据通信设备STA在地铁无线通信系统中移动与切换的适用性和局限性出发,研究切换数据损耗、响应时间、资源分配与消耗、移动和漫游协议等,分析各个模块功能,并对其进行比较分析,以选择一个适应地铁系统的最佳设计方案。
Solving the problem of high-quality mobile communications of subway passengers,it is one of the important re- search topics of modern subway. Subway system is a closed environment, it has strong signal in subway wireless communi- cation system, but the subway is in motion, data switching and link is the the key technologies to impact the quality of communication. From the mobility of data communication device STA in the subway wireless communications system, re- search the switched data loss, response time, resource allocation and consumption, mobile and roaming agreements, ana- lyzes and compares the functions of each module, to select the best design scheme which adapts subway system.
