Enriched conference

With the increasing proliferation of mobile devices with advanced capabilities and coupled with increasing deployments of IMS networks that combine interactive multiparty communications with quality of service features, multimedia conferencing is a service that many end-users will now be able to enjoy. In this paper we propose new techniques to be adapted while initiating a conference in order to have enriched user experience and also optimized utilization of network resources during conference setup. Specifically we propose two methods, presence based instant conference and ordered invite, for initiating conference which the conferencing server applies before initiating the conference.
