中国铁路综合数字移动通信网络与GSM-R的应用

CR Integrated Digital Mobile Communication Network and the Application of GSM-R

目前,中国铁路既有无线通信系统包括无线列车调度电话、站场无线通信、集群移动通信等系统。这些通信系统已不适应中国铁路信息化、调度指挥和安全生产,以及青藏铁路、高速铁路和客运专线等技术的发展需要。在分析中国铁路运输特点的基础上,提出了中国铁路综合数字移动通信网络的网络模型和业务模型,及二次开发的重点。

The existing CR radio communication system includes train dispatching telephone, yard communication, and trunkmobile communication systems. The existing system cannot meet the demand of the CR informationization, dispatching commandand safe production and Qingzang railway, high-speed railway as well as the dedicated passenger transport. Based on the analy-sis of the characteristics of the CR transportation, it puts forward CR Integrated digital mobile communication network model andservice model as well as the focuses for secondary development.
