摘要
本文介绍了NGN测试仪中,SIP监测系统的总体设计的思想和功能。在分析基于RFC3261的SIP协议消息结构的基础上,研究了SIP的解码方案、CDR合成技术和多项统计方法,通过现场实测保证了SIP监测系统的稳定性和相关理论算法的可行性。
Introduced an overall framework and functions of SIP monitoring system using for the NGN communication test instrument. According to the structure of SIP protocol based on the core specification RFC3261, elaborated the scenarios of SIP decoding, obtaining CDR and several strategies for SIP statistic respectively. Finally, the implement result from real-time dynamic data confirmed that the SIP module is reliable and at the relative theories is feasible.
