Dynamic Session Modification between Multiple Devices in the IMS/MMD Architecture

Multi-device communication will be usual in a ubiquitous networking environment with features of heterogeneity and ubiquity. Under such circumstances, users shall be able to communicate via a method optimized based on their surroundings and preferences. This paper shows a dynamic session modification mechanism that enables users to switch their communication resources via operation from remote devices during a session. With this in mind, the session manager and presence manager are introduced as application servers (AS) in IMS/MMD infrastructures. A prototype system, including implementation on a cellular phone, and performance evaluations are also shown.
