中文摘要：

为了应对移动即时通讯针对网络管理和多媒体信息共享等方面出现的需求，基于可扩展的消息和出席信息协议（extensible messaging and presence protocol，XMPP）和网络管理功能模型提出了移动多媒体即时通讯服务架构和实现机制．在标准XMPP基础上扩展通信协议，支持多媒体信息共享．适时地在设计框架内加入网络管理功能，便于管理各项即时通讯服务．实验结果表明，按照该方案开发的实验系统运行稳定，能按要求提供多媒体信息共享和网络管理功能，快速处理用户即时消息，平均错误率稳定在0．05％左右．

英文摘要：

A design based on XMPP and FCAPS model was provided to meet the rapidly growing and changing mobile IM needs. The protocol extensions based on the standard XMPP had been used to support muhimedia information sharing. The design added network and systems management to manage mobile IM services. An experimental system was developed to verify the design. It was demonstrated by experiment that the system could build stable and efficient mobile IM services with important management and essential search functions. The system processes a message rapidly and the error rate is very low.
