Bian Xuegong · Jisuanji gongcheng · 2005
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.
