摘　　要：3GPP提出的IP多媒体子系统(IMS)技术体现了通信网和因特网技术的结合、下一代网络和3G网络技术的结合,已受到通信界和信息技术界的广泛认同,成为固定和移动网络融合的核心技术。其网络融合综合了互联网IP技术、软交换技术和蜂窝核心网技术,业务融合综合了开放式Parlay/OSA技术和Web Services技术,管理融合综合了电信网管理、IP网络管理和策略控制技术。面对互联网的严峻挑战,各个标准化组织正通力合作推进IMS的发展,统一IMS、业务代理和有管理的P2P业务是进一步研究的重要内容。IP Multimedia Subsystem （IMS） proposed by 3GPP embodies an integration of communication network with Internet technology and a fabrication of Next Generation Network （NGN） with 3G technology. IMS has been widely acknowledged in telecom industry and Information Technology （IT） as the core technology for Fixed-Mobile Convergence （FMC）. Network convergence is the integration of Internet IP, SoftSwitch and cellular core network technology. Service convergence is the synthesis of open Parlay/OSA technology and web service technology. Management convergence is the interfusion of telecom network, IP network management and policy control technology. To cope with a grim challenge from Internet, all standardization organizations are interacting to push forward the further development of IMS. A unified IMS, proxy service and managed P2P service are important subjects for further research.
