Abstract: A method and system for establishing the ISC session among one or more communication devices for a content viewing and/or a communication to enable integration of the content viewing and the communication is provided. The integration or convergence of the content viewing and the communication provides an immersive user experience to one or more ISC users in the ISC environment participating in the ISC session including a self ISC session, a one to one ISC session or a group ISC session. The method allows an initiator ISC client to append one or more first parameters in a first SIP INVITE for the content viewing and one or more second parameters in a second SIP INVITE for the communication. The common appended parameters such as an ISCConvergenceID indicate the media function and the communication function to integrate the communication with respect to the content viewing.

Abstract: A method and system for establishing an integrated group Immersive Social Center (ISC) session for a content viewing and a communication by an ISC server to deliver contents associated with a content interest is disclosed. The group ISC session is established for a pre-defined group created with members indicating interest in the group ISC session initiated by an initiator ISC client. The method allows the ISC server to receive the content interest from an initiator ISC client. Further, the members of the pre-defined group can schedule time for the integrated group ISC session. The content interest received from the initiator ISC client is selected by the ISC user of the initiator ISC client from a personalized contents list, based on static preference or on demand preference of the ISC user, sent by the ISC server or an ISC XML Document Server (XDMS).
