Design and implementation of SIP-based ad hoc conferencing system

Abstract

The Session Initiation Protocol (SIP) is an IETF (Internet Engineering Task Force) standardized signaling protocol that can establish, modify, and terminate multimedia sessions or calls over the Internet. Combining SIP and agent technologies, a SIP-based ad-hoc meeting management system is proposed in the thesis. Using a precisely defined procedure, the system architecture and scenarios are designed to solve problems such as, (1) How to start and manage an ad-hoc conference? (2) How do users indicate their private constraints for private services? (3) How do users initiate and manage a sidebar association in an on-going conference? (4) How do conferencing participants identify other conference members and be notified of the changes made in an on-going conference? The proposed SIP-based ad hoc meeting management system is capable of creating and managing conference sessions in an ad hoc environment, where participants are nomadic users. With several features, the SIP-based ad hoc meeting management system supports various services to users and provides mechanism to realize them. (Abstract shortened by UMI.)
