摘　　要：目前GSM-R网络接口监测主要集中在Abis接口、A接口、PRI接口、Gb接口、Gi接口等,对空中接口(Um接口)的监测较少,因此在对CTCS-3无线超时和降级问题进行分析处理时无法准确定位故障。为了提高GSM-R网络维护效率,提高故障定位效率和准确率,保障高速铁路安全运营,该文采用通用软件无线电平台采集GSM-R空口数据,通过数据分析完成信令解析,实时监测信令交互过程,为故障用户的信令回溯和消息追踪提供有力的分析手段。The current interface monitoring of GSM-R network mainly focuses on Abis interface,A interface,PRI interface,Gb interface,Gi interface,etc.,and the monitoring of air interface(Um interface)is rare.Therefore,when analyzing and processing the wireless timeout and degradation of CTCS-3,it is impossible to accurately locate the fault.In order to improve the efficiency of GSM-R network maintenance,increase the efficiency and accuracy of fault location and ensure the safe operation of high-speed railway,this paper adopted the general software radio platform to collect GSM-R air interface data.Signaling analysis system was completed through data analysis,and it could monitor the signaling interaction process in real time,which provided a powerful analysis means for signaling backtracking and message tracking of fault users.
