摘　　要：随着我国高速铁路网的大规模扩张,原有的铁路无线接入技术在数据传输速率方面已经不适应新的通信业务需求,因此在铁路通信系统的无线接入专网中引入宽带无线通信技术已经成为必然趋势。结合高速铁路的通信业务需要,根据CTCS列控数据传输标准对铁路通信系统的QoS保障要求,分析比较了当前宽带无线通信协议中的几种接入网架构,并设计了高铁宽带无线通信接入网架构。With large-scale expansion of China＇s high-speed rail network,original railway wireless access technology can no longer to meet the demands of communication services in data transfer rate.Therefore it is an inevitable trend to introduce broadband wireless communication technologies into the wireless access private network of the railway communication system.Combining the demands of communication services in high-speed rail and according to QoS assurance requirement of railway communication system by CTCS trains control data transmission standard,we have analysed and compared a couple of access network architectures of current broadband wireless communication protocols,and design the access network architecture of broadband wireless communication system for high-speed rail.
