This paper takes the architecture features and functions of GSM-R Macro Site equipment in the existing network as the research object,and demonstrates,through RAMS analysis and engineering tests on the operating network,that the reliability,availability and maintainability of a single set of Base Transceiver Station(BTS)currently in use can be improved by enhancing the redundancy of key modules,so as to reduce the probability of the failures and out-of-service of base stations in the network.Reducing the impact of single-module failures of GSM-R base stations on railway services including CTCS-3,and lowering the maintenance timeliness requirements for BTS module failures along the line,both lay the foundation for the continuous,long-term and stable operation of GSM-R Macro Sites in the network,and provide a solid base for safe and stable railway operation.
