Enabling Session Mobility in Full Mesh Conferencing Model

Enabling service continuity from one user´s device to another one while maintaining communication is a real need to maximize end-user service experience and to benefit from the capacities of each available device in the user environment. This service ubiquity can be realized by session mobility between devices. Many session transfer use-cases can be supported to enable different service modes and options within a two-party communication context. Otherwise, enabling session mobility in a multiparty conferencing, like the full mesh communication model, can be more complex. This work describes a solution to support session mobility options in the full mesh conferencing by extending existing abstract message protocol and to map them using Session Initiation Protocol (SIP). Introducing session mobility in full-mesh conferencing causes different extra message traffic depending on the used mode (Mobile Node Control Mode or Session Handoff Mode). At the end, we propose a comparative study to determine the message traffic for each mode depending on the number of participants and the events included in conferencing scenarios.
