摘要
首先简要介绍了软交换的定义和功能,接着阐明了软交换设备的组网结构、实现软交换设备互通的两种协议,即:SIP-T和BICC,并对其进行了分析和比较,然后给出了用SIP-T实现软交换设备间互通的典型流程以及ISUP和SIP在消息级和参数级的映射和转化方法。
Firstly,this paper introduces the definition and function of softswitch briefly.Then,it interprets the structure of MGC in softswitch system,two kinds of protocols of interworking between MGC and MGC,and compares the protocols.Following,the paper gives the typical call flows in according to SIP-T protocol,and the methods of mapping and translation in message level and parameter level between ISUP and SIP.
