成灌线GSM-R系统互联及测试研究

Interconnecting and Testing of GSM-R System for Chengdu-Dujiangyan Railway Line

成灌线GSM-R系统的互联实现了国内诺西、华为和北电3个GSM-R网络设备商设备的互联,成灌线成都节点是我国第一个应用于现网的基于软交换平台的GSM-R网络,具有重要的历史意义。阐述了成灌线GSM-R系统互联的方案及实施过程,并分析了互联测试及故障解决方案。

The GSM-R system of Chengdu-Dujiangyan railway line has realized interconnection of GSM-R network equipment from different suppliers（Nokia-Siemens,Huawei and Nortel）.As the GSM-R network based on soft-switch platform,Chengdu node of Chengdu-Dujiangyan railway line is firstly applied to the existing network in China,which has an important historical meaning.The paper elaborates the interconnection scheme and implementation process of the GSM-R system for Chengdu-Dujiangyan railway line,and analyzes the interconnecting test and the solution of troubleshooting.
