本文根据目前3GPP和IETF以及OMA对IMS中会议、群组、Presence以及消息类业务的研究,提出了在IMS环境下组合类多媒体会议(融合消息,群组、电子白板和应用共享)的设计实现方案,并描述了几个具体的业务场景流程。该方案相对于现有的复杂的基于H.323的会议系统更加简单实用。
According to the current research on IMS conference, group, Presence and messaging services by 3GPP, IETF and OMA,a design scheme for combined multi-media conference which combined message, group, whiteboard and application sharing in IMS environment was presented. And a flow chart for several service scenarios was described in this paper. It is more practical than the current complicated conference system based on H.323.
