摘要
高速铁路建成后,运营商为了解决由于CRH车体密封性好、损耗高,列车速度快等原因,车厢内通信质量明显下降而进行了高铁专网覆盖。为保障高速铁路通信网G S M-R系统的稳定,研究GSM-R系统与GSM系统兼容性测试的办法。
High-speed railways should be covered with private networks to increase the communicationquality inside cars due to CRH high-speed trains with well sealed car body, high signal loss and high speed.In order to ensure the stability of GSM-R systems of high-speed railway communication networks, thispaper studies a test method of system compatibility between GSM-R system and GSM system.
