GSM-R核心网改造综合技术研究与应用OA

China's railway wireless communication system adopts the GSM-R mobile communication system,which includes two parts:wireless access network and core network.The GSM-R core network is the core of the entire network system,and its reliability and security are crucial.This paper studies the core network equipment networking mode,cutover business system content,testing and protected mode in the process of core network transformation.The research improves the cutover efficiency of existing lines,reduces the impact on existing equipment during construction,and decreases traffic safety risks,so as to provide valuable experience for similar construction in the later stage.
