基于Gb接口信令分析的深圳站进路预告故障处理

进路预告信息通过GPRS网络传递,是CTC与CIR之间传输的重要业务之一,是保障铁路运输安全的重要手段。围绕广深线深圳站进路预告接收异常问题,进行故障定位,判断为因CIR发生小区重选导致短暂脱网丢包,从而影响到深圳站进路预告接收,为此提出调整天线倾角及重选参数的优化方案,为相关铁路单位运维工作提供参考。

Handling of Advance Information Fault Occurring at Shenzhen Station by Analyzing Gb Interface Signaling

The advance information is transmitted via GPRS network as one of key services transmitted between the CTC and the CIR and an important means to ensure the safety of railway transportation.For the abnormalities in receiving advance information at Shenzhen station in Guangzhou-Shenzhen line,the fault is pinpointed by analyzing the cause and it is found that transient off-network and packet loss was caused due to the CIR’s cell re-election,thus affecting the reception of advance information at Shenzhen station.So,it is proposed that the antenna inclination should be adjusted and re-election parameters be optimized,offering reference for railway operation and maintenance personals.
