Abstract

Users with several devices need a convenient mechanism to transfer running service sessions from one device to another device. This paper proposes a framework that allows session mobility without modifications on the communication partner's system from application layer down to network layer. That means we can transfer ongoing sessions with minor interruptions of the communication and thus call it complete session mobility. Due to the framework's flexibility we support a multitude of technologies across all layers. The architecture has been verified by a prototype that has been implemented on a Linux system.
