郑西客运专线GSM-R高速网络优化的经验

Experiences of GSM-R High-speed Network Optimization of Zhengzhou-Xi’an DPL

随着郑西、武广等客运专线的相继开通,我国高速客运专线建设进入了一个高速发展的时期,GSM-R网络作为承载CTCS-3级列控安全数据传输的平台,其系统优化和稳定工作对于列车高效安全运行至关重要。本文主要从工程角度探讨和总结郑西客运专线GSM-R网络在高速条件下的优化方法,着重从网络覆盖优化、越区切换优化和网络服务质量测试优化等方面进行阐述。

Along with the Zhengzhou-Xi’an, Wuhan-Guangzhou DPLs were put into operation, China high- speed DPL construction entered a period of rapid development. GSM-R network, as the carrying foundation of CTCS-3 train control secure data transmission, it’s system optimization and stabling work is very important for effi cient and safe operation of train. The paper explores mainly optimization mode of GSM-R network under the high-speed condition from the point of engineering design, the focus is on the network coverage optimization, handover optimization and test optimization of network QoS, etc.
