【摘要】 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。模型包括会议配置、用户管理、Floor control、应用会话管理和网络管理各组件,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SOAP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。更多还原

【Abstract】 This paper identifies the requirements for conference control and presents a centralized conference control model on the base of some scholars research works. The model employs SIP as singling control protocol and comprises some components such as conference configuration, user management, Floor control, application session management and network management. To implement conference control, message mechanism should be employed. This paper adopts a popular solution in which SOAP is used as conference command and SIP event framework as conference notification. The model proposed in this paper has been successfully applied to a SIP-based real-time multimedia conference system. The conference control results demonstrate that this model is applicable and effective.更多还原
