Research on Reliability Enhancement of GSM-R Digital Mobile Communication Base Station Equipment.

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.
