浅析列车进路预告失败问题的分析方法

Analysis Approach of Failure to Advance Notice of Train Route

列车进路预告信息传送是GSM-R网络中GPRS系统的一项重要业务,发生列车进路预告失败问题时,分析并查找出故障点,涉及CTC系统、GPRS系统设备、GPRS终端及数据通信网等诸多环节,是GSM-R系统维护管理中的一个难题。本文结合一个典型案例的分析,探讨了列车进路预告失败问题的分析方法。

Transmitting advance notice of train route is one key service of the GPRS of a GSM-R network. When advance notice of train route is failed, it is difficult to analyze and seek out the fault point because the problem might involve CTC system, GPRS system equipment, GPRS ter- minal, and data communication network, which remains as a crux in the maintenance and man- agement of GSM-R system. Combined with the analysis of a typical case, it is explored how to analyze the failure of advance notice of train route.
