GSM-R与无线列调共存区域列车无线通信方案研究

Research on Radio Communication Scheme in Co-existence Section of GSM-R and RTDCS

随着铁路建设的推进,传统的450MHz列车无线调度通信系统(无线列调)和900MHz的数字移动通信系统(GSM-R)两种无线列车通信制式并存的区段越来越多。通过简单介绍这两种列车无线通信系统主要业务的实现方式,分析两种无线制式并存和衔接区段列车无线通信可能的方式和方案设计需要考虑的因素,并结合多个典型案例阐述各方案的设计要点和存在的问题。

With the advance of railway construction,co-existence sections of the traditional 450 MHz radio train dispatching communication system（RTDCS） and 900 MHz GSM-R digital mobile communication system become more popular.The paper introduces briefly service-implementation manners of the two main train radio communication systems,analyzes possible manners and factors to be considered during scheme design of the two systems in co-existence sections,and describes the design features and problems based on multiple typical cases.The measures and schemes are presented as references for train radio communication engineering design,construction and application.
