摘要
CTCS-3列控系统使用GSM-R网络作为车载和地面之间数据承载通道。通过GSM-R网络空中接口(Um接口)监测能够分析车地之间网络信令和用户数据,能够为CTCS-3列控系统运营维护和通信故障诊断提供依据。在对3GPP协议深入分析基础上,提出一种基于GSM-R无线Um接口信令和业务数据的动态监测方案,重点阐述方案的关键技术,系统结构和实现方法,并且通过实验室测试对系统进行论证。该系统填补了目前GSM-R网络监测系统只针对有线接口进行监测的空白。
CTCS-3 train control system uses GSM-R network as the vehicle-ground data bearing channel. The air interface （Um interface） of GSM-R network is used to monitor and analyze vehicle-ground network signaling and user data, in order to provide the basis of operation, maintenance and communication fault diagnosis for the CTCS-3 train control system. Through the analysis of 3GPP protocol, the paper presents a dynamic monitoring scheme based on GSM-R Um interface signaling and operation data, including principles of the main technologies, system architecture, implementation ways and lab testing results. The system can fill the gaps in monitoring wireless interface function of GSM-R network monitoring system.
