摘　　要：针对目前CSD链路(Corporate Synergy Development,电路交换数据业务)异常导致CTCS-3(Chinese Train Control System-3,三级中国列车运行控制系统)发生无线通信超时故障时,现有三接口监测手段无法对故障原因进行准确定位的问题。提出新的接口监测技术,在BSC(Base Station Controller,基站控制器)和TRAU(Transcoding and Rate Adaptation Unit,码型转换和速率适配单元)之间增加Asub接口监测设备,对其进行整体的系统设计和功能研究,通过Asub接口监测数据,成功实现CSD链路异常故障精准定位,为无线网络优化及减少无线通信超时提供有效的帮助。When CCTS-3 Wireless Communication Timeout fault occurs due to CSD Link Exception,the existing three-interface monitoring method cannot accurately locate the fault cause.A new interface monitoring technology is proposed,and Asub Interface monitoring equipment is added between BSC and TRAU,and the overall system design and function research are carried out on it.Through the monitoring data of Asub Interface,CSD Link Exception is accurately located successfully,providing effective assistance for wireless network optimization and reducing Wireless Communication Timeout.
