摘　　要：随着网络技术及通信技术的快速发展,传统电信网络与下一代网络之间的互通成为一个很热门的话题。网络互通的主要问题之一是承载协议的相互转换,网关提供了一种信令转换的桥梁。从此问题出发分析了PSTN网与IMS网间的互通,并对两网络中的相关协议(SS7和SIP)展开讨论,提出了一种互通模型,提供了一套在实际项目中证明可行的实现方案。With the rapid development of the network technology and communication technology, the interoperability between traditional telecommunications networks and next-generation network becomes a very popular topic of conversation. One of the main issues about network interoperability is transformation of protocols. And signaling gateway provides a conversion bridge. This paper started from the interoperability problem of PSTN network and the IMS network, analyzed the relevant protocols （ SS7 and SIP） in the two networks, put forward an intercommunication model, and provided a set of feasible implementation in an actual project.
