摘要
结合对SIP(Session Initiation Protocol)协议的深入分析,采用正则表达式匹配方式进行消息解码,着重分析SIP呼叫合成的算法,使用Hash技术有效解决了CDR合成效率低下等关键难题。该方案在已商用的软交换集中监测系统中进行了测试和验证,效果良好。
According to the analysis of SIP（ Session Initiation Protocol）, the regular expression matching method is used to decode message. The principle and algorithm of CDR（Calling Detail Record） synthesis am presented and a Hash method is adopted to solve the problem of low efficiency in getting SIP CDR. The test results from practical application of soft-switching centralized monitoring system have shown the good perfomkance of the scheme.
