摘要 3GPP IMS与WLAN之间的互通可以将IMS核心网络业务扩展到WLAN接入环境中,同时使WLAN成为3GPP系统的一种补充接入技术。介绍了3GPPIMS的网络结构,分析了IMS中SIP协议及其扩展,重点讨论了IMS与WLAN的互通模型,以及如何支持3GPP目前定义的几种业务互通等级。 The interworking between 3GPP IMS and WEAN extends the IMS core network service to WEAN access environment, and makes WEAN become a complementary access technology of 3GPP system. This article introduces the 3GPP IMS architecture, analyzes the Session Initial Protocol and its extension in IMS. Discussions are also conducted on the interworking model and how to support different levels of service interconnection which defined in 3GPP.
