摘　　要：STP作为全路GSM-R网络的心脏,提供各端局MSC至HLR、各端局SGSN至HLR、各端局MSC至SCP、SCP至HLR、MSC间跨局呼叫时的信令转接功能。结合GSM-R网络组网架构及铁路行车通信业务运用,对全网信令路由及信令消息的转接进行详细研究和分析,并针对可能发生的设备隐性故障,判断故障点及影响范围,进而实施有效、及时的应急处置,为日常维护、故障分析、应急处置等提供参考。As the“heart”of GSM-R networks across China’s railway network,STP(Signaling Transfer Point)provides the function of signaling transfer from local MSC to HLR,from local SGSN to HLR,from local MSC to SCP,from SCP to HLR,and during inter-local calls between MSCs.Based on the networking architecture of GSM-R networks and the application situation of GSM-R networks for communication services in railway train operation,this paper conducts detailed research and analysis on the signaling routing and signaling message switching across China’s railway network,and judges the fault point and impact scope of the potential hidden equipment faults,to take eff ective and timely emergency disposal measures.Thus,it provides reference for day-to-day maintenance,fault analysis and emergency disposal.
