Today users are getting used to have many heterogeneous devices available in their surroundings. This opens great opportunities to build pervasive communication environments. Pervasive communications are usually user-centric in nature, as they should target sessions to users rather than their specific devices. Mobility is a key issue in such context: users often move and that implies different devices and networks to become available to them dynamically. As a matter of fact, terminal handovers and session migrations could negatively impact the enjoyment of multimedia content in such scenarios. In this paper, we propose a user-centric mobility framework for multimedia interactive applications. To this aim, we implement the concept of Personal Address, that is a network identifier assigned to users. Our mobility framework exploits this concept to accounts for all aspects of mobility. Moreover, we describe our deployment for Voice-over-IP sessions; finally, we report the results from our experimental testbed.
