The Research And Applications Of The Interface For GSM-R Network Monitoring System In High Speed Railway

With the great development of railway construction in recent years,the GSM-R network is massively applied in every line.GSM-R interface monitoring technology is data monitoring of each interface circuit of GSM-R network which is on the run.It's able to save signaling and business data which is transmitted through GSM-R network in the real time,and can extract and reproduce communication timeout,call failure and other faults,assists maintainer to analyze the cause of the problem,and so on.In order to monitor GSM-R network better,find and predict fault easily,deal with failure and avoid failure,this paper puts forward the whole interface monitoring technology.This technology is a supplement and perfection of traditional three interfaces monitoring technology.The current three interfaces monitoring implementation mainly realizes the real-time monitoring,data storage and analysis function to A and Abis interface signaling and PRI interface signaling and data of electric classification.And,it can also monitor the running status of equipment itself but for Gb,Gn,Gi,or Um interface.In order to further strengthen the comprehensive handling for GSM-R equipment using quality,more accurately locate the cause of the problem,and improve the efficiency of fault handling and network maintenance,it is necessary to conduct A comprehensive monitoring for Gb,Gn,Gi,Um Abis interface,and Abis isn't on the C3 line,A and Gn interfaces,etc.Especially the monitoring aims at signaling data and business data in packet domain,can effectively solve the railway scheduling command communication,train number issued and route forecast.The highlight of this paper is to analyze the construction and application of the Gb,Gn,Gi,and Um interface in engineering.Among them,Gb,Gn,and Gi interface monitoring provide powerful means to solve the problem caused by the failure when GSM-R/GPRS sends forecast scheduling command,and train route;besides,it's also important tool of GPRS network optimization;Um interface monitoring is to address air interface monitoring down the Abis interface.The interfaces for all networks,from the perspective of the actual implementation of the project and description of site maintenance in mind.Optimize workflow GPRS wireless network with the GSM wireless network optimization process is similar,but the means of the specific configuration of data involved,performance concerns,analysis and processing there is a big difference.Statistical data network configuration data is the most basic data,the correct network configuration,direct influence on the network performance is good or bad.It should be collected before specific optimization configuration data,and periodic verification of configuration data,to understand the structure of the network,is set for the correct analysis,locating network problems and develop optimization strategies to provide a guarantee.Configuration data including BSS and PCU two parts: GPRS system for the first time in the mobile network packet technology,introduces the concept of IP,and its business model and optimizing maintenance ideas and GSM compared to produce significant changes.GPRS is based on GSM wireless network optimization network optimization based on a new,complex and difficult systems engineering,this paper work experience in the field troubleshooting for GPRS wireless network optimization are discussed and summarized and analyzed to give a full interface to monitor than triple interface monitoring conclusions so comprehensive and effective monitoring of GSM-R network,to ensure the safety of train travel purposes.
