| 摘 要： | 为解决3G核心网话音业务和扩展业务过快增长带来的核心网接口监测难题,本系统通过监测A接口、Nb接口的原始信令数据并对其进行解码分析,得到网络中与话音质量相关的核心指标,在信令处理层引入预处理模块,通过对RTP数据流和对应信令过程的关联重组数据,降低了数据流量,完成了端到端的话音质量分析。本方案已应用于3G核心网话音质量监测系统中,效果良好。

| Abstract: | Through monitoring A and Nb interface’original signaling data and decoding analysis data,the system gets core index related with voice quality in the network.A feasible pre-implementation module for signaling processing layer is proposed.Through doing connection between the RTP flow and the corresponding signaling process,the system restructured data and reduced the interface data flow.The solution has implemented in 3G core network voice quality monitoring system,and has a good effect. |
