Automated Management of User Centric Session in NGN

Nowadays, with the rapid development of Next Generation Network (NGN), personalized applications, which can dynamically adapt to the users' mobility, requirements and preferences become more and more demanding. On the contrary of the other points of view (eg. application centric), "User Centric" approach follows no long client server architecture and becomes one of the most important challenges of Next Generation Service (NGS). Current technologies, such as Web2.0, cannot satisfy the NGS requirements. In this paper, we propose "User Centric session" based on the Virtual Private Service Network (VPSN) model. This idea allows automated management of session service according to the mobility and maintains dynamically the personalized service composition. By implementing the scenarios of both multiple sessions and User Centric session, we do a comparison to prove the feasibility and the advantage of our approach.
