Patent

CA 2684500

There is described a method for enabling session mobility in a multi-participant IP-based multi-media communication network in full-mesh conference model, the method comprising: mapping a full-mesh communication protocol to a Session Initiation Protocol (SIP); defining an extended message protocol including new message mechanisms to support session mobility options; mapping the extended message protocol to the Session Initiation Protocol; and adding headers to mapped messages from the extended message protocol and from the full-mesh communication protocol to comply with full-mesh message signalization protocol mechanisms.

Le procédé décrit permet une mobilité de session dans un réseau de communication multimédia basé sur IP à participants multiples dans un modèle de conférence de maillage intégral, le procédé comprenant : le mappage d'un protocole de communication de maillage intégral sur un protocole d'ouverture de session (SIP); la définition d'un protocole de message étendu comprenant de nouveaux mécanismes de message pour supporter des options de mobilité de session; le mappage du protocole de message étendu sur le protocole d'ouverture de session; et l'ajout d'en-têtes aux messages mappés à partir du protocole de message étendu et à partir du protocole de communication de maillage intégral pour se conformer aux mécanismes du protocole de signalisation de message de maillage intégral.
