ISDN与GSM间PRI接口通信质量监测系统分析

Discussion on PRI Interface Communication Quality Monitoring System between ISDN and GSM

随着GSM网络的建设和发展,对于通信质量提升及故障排查手段的要求越来越高。通信接口间的质量问题影响面更大,造成的损失尤其严重。可以通过对接口上呼叫的信令流程、数据传输过程及线路状态等进行完整的监测和记录,并采用综合分析和联合诊断技术、多层协议分析与解码技术、多用户实时跟踪与查询技术等手段,进行故障定位和分析、通信网络优化与维护以及干扰分析,提供GSM网络发生故障的位置。本研究重点讨论ISDN与GSM间PRI接口通道质量的监测。

With the construction of GSM in China, the requirement for improving communication quality and troubleshooting means is also increasing. Among them, the quality problems between communication interfaces have a greater impact on the area, resulting in particularly serious losses. Through monitoring and recording the signaling process, data transmission process and line status of calls on the interface, and using comprehensive analysis and joint diagnosis technology, multi-layer protocol analysis and decoding technology, multi-user real-time tracking and query technology, fault location and analysis, communication network optimization and maintenance and inter- ference analysis are carried out to provide fault location for GSM network. This paper focuses on the quality supervision of PRI interface channel between ISDN and GSM.
