数字集群通信系统的特点及在新建铁路上的应用

集群通信系统是基于数字时分多址(TDMA)技术的移动通信系统,可实现多业务、高质量、高速率的移动通信。集群系统由集群交换机、集群基站、终端设备、网管工作站、铁塔和天线、调度系统等组成,多种呼叫优先级、故障弱化功能、虚拟网功能等特点适应了铁路无线通信的需求。

The digital clustered communication system is of the mobile communication system based on Time Division Multiple Access (TDMA) technology, which can realize the mobile communication with multi-business, high quality and high-speed transmission. The digital clustered communication system is composed of switching equipment, base station, terminal equipment, administration of network, iron tower and antenna, dispatching system etc. The system, with characteristics of multi-priority level for calling, fallback function, VPN function etc. is suitable to the demand of railway wireless communication.
