摘　　要：由于GSM-R无线网络采用不同厂家的设备,设备硬件构成、冗余方式不同,当GPRS核心网与无线网的调测出现问题时,需要通过接口信令的捕捉,对照协议规范分析。为此简要介绍Gb接口协议栈及主要的协议消息,探讨Gb接口规划、调测方法及各消息的作用,并就诺西设备接入核心网的故障排除进行分析。Due to the diversity of equipment composition with its equipment from different manufacturers, it is requi according to the protocol when problems is encountered in and redundancy of GSM-R wireless network red to capture the interface signal for analysis the testing of the GPRS core network and the wireless network. Therefore, the Gb interface protocol stacks and the main protocol messages is briefly introduced and the Gb interfaces planning and test methods as well as the role of each messag are explored, and the troubleshooting of NSN devices connected to the core network is also analyzed.
