摘　　要：介绍CTCS-3+ATO模式列控系统的运行方式和GPRS的相关参数。通过分析国内首条使用CTCS-3+ATO模式高铁线路运行1年多以来的监测数据,可见高速铁路ATO业务在功能和性能方面完全满足国铁集团制定的规范要求,并对原CTCS-3业务没有任何影响,证明使用分组域GPRS网络承载列控类业务的可行性。为增强GPRS分组域通道的可用性,保证ATO业务的正常运行,针对BSC资源利用、小区重选和ATO设备保护功能等方面提出合理建议。This paper introduces the operation mode of CTCS-3+ATO train control system and the relevant parameters of GPRS.By analyzing the monitoring data of the first domestic high-speed railway line using CTCS-3+ATO mode for more than one year,the high-speed railway ATO service fully meets the requirements of the specifications formulated by China Railway Group in terms of function and performance,and has no impact on the original CTCS-3 service,which proves the feasibility of using packet domain GPRS network to carry train control services.In order to enhance the availability of GPRS grouped domain channels and ensure the normal operation of ATO,this paper puts forward reasonable suggestions on BSC resource utilization,cell reset and ATO device protection.
