STP在GSM-R网络中的主要作用及故障判断
Main Roles and Fault Diagnosis of STP in GSM-R Networks
摘要
Abstract
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 effective and timely emergency disposal measures.Thus,it provides reference for day-to-day maintenance,fault analysis and emergency disposal.关键词
