A conference control model between a web server and a telecom application server

The paper proposes a conference control model between a web server and a telecom application server, referred to as the Conference Directed Graph (CDG), and describes an asynchronous communication mechanism between them. The Corba Interface Definition Language (IDL) interfaces are defined, and a message sequence chart is illustrated. This web conference control model provides conference users with a new approach to manage and control a conference and the participants. The performance of the system prototype is analyzed and verified in the 863 project named "The Multimedia and Mobile Services Enabled Soft-switch System".
