在前人研究的基础上提出了一种独立于应用的、适用于集中式会议的会议控制模型。系统实现的集中的会议管理平台，可以有效的管理各种会议资源，方便各种软硬件媒体资源的接入。采用了 SIP 协议作为会话控制协议。会议控制消息分为命令和通知两种。会议命令使用 XMLRPC 协议实现，会议消息采用了 SIP 事件通知机制。该会议控制模型被成功地应用于基于 SIP 的实时多媒体视频会议系统。实践表明，该会议控制模型是合理的、有效的。

This paper identifies the requirements for conference control and presents a centralized conference system model on the base of some scholar research works. The model employs SIP as singling control protocol and comprises some components such as conference configuration, user management, media control, application session management and net-work management. To implement conference control, message mechanism should be employed. This paper adopts a popular solution in which XMLRPC is used as conference command and SIP event framework as conference notification. The mod-el proposed in this paper has been successfully applied to a SIP-based real-time multimedia conference system. The confe-rence control results demonstrate that this model is applicable and effective.
