摘　　要：全 IP网络技术是当今移动通信领域的研究热点之一 .3GPP与 3GPP2除了独立研究全 IP网络技术外 ,还将其作为 WCDMA和 CDMA2 0 0 0核心网融合的技术基础 .软交换是 WCDMAR4 / R5核心网络的重要技术特征 .文中对 3GPP和 3GPP2的全 IP网络的网络参考模型进行了较为详细的描述 ,同时对全 IP网络研究的一些问题进行了探讨 .借助软交换 (Softswitch)技术对WCDMA R5核心网的技术构成进行了分析 .介绍 WCDMA R5版本中基于 IP的 RAN及 HSDPA技术 .All IP network is a hotspot today in the field of mobile telecommunication and basic technique for the confluence of core networks WCDMA and CDMA 2000; while softswitch is the important technical characteristic of core network WCDMA R4/R5. Both of these technologies are formulated respectively by 3GPP and 3GPP2 as the third generation partnership projects and standardization organizations. The present work includes 3 parts. Firstly, the reference models of all IP network formulating respectively by 3GPP and 3GPP2 are described in detail, and moreover, some problems on all IP network are discussed. Secondly, the technical constitution of the core network WCDMA R5 is analysed by drawing support from softswitch technology. Finally, the IP based technology of RAN and HSDPA in WCDMA R5 edition is presented.
