Session Initiation Protocol (SIP) and Web service are the de facto standards for Voice over IP applications and distributed system, respectively. Although they do not be used to define multimedia conferencing directly and completely, many proposals, drafts and papers suggest extensions and solutions to this essential service. However, as the spring up of the Web service standards and technology, some traditional communication systems should be restructured and modified, including the multimedia conference framework based on SIP and Web service. In this study, a hybrid multimedia conference framework is first propose, which consist of low latency services, primitive and composite conference services. Under this framework, a multimedia conference can be organized and controlled conveniently with the property of loosely coupling and extensibility. Then the primary components of a conference control are introduced followed by the detailed design exemplified by some typical scenarios, which is compared to other possible design approaches. Finally, a specification of orchestration implementation which realizes the synthesis of the conference control functions is introduced to illustrate the feasibility of this design.
