Living in a world surrounded by multiple devices such as smart phone, laptop, desktop PC and even tablet, it is important for the user to seamlessly transfer his/her session across these devices in a ubiquitous manner according to user preferences. While most of the systems either rely on realtime location tracking of the target device, or require users to remember the contact or IP address of the target device for the transfer, we propose in this paper an automated session transfer mechanism leveraging on the registration information which are readily found in the IP Multimedia Subsystem (IMS) core. We explain in this paper the system architecture and signaling flow of our prototype implementation. Results showed that our proposed mechanism for session transfer over both wired and wireless access network took 202ms and 388ms respectively, which stays within the ITU-T recommendation of 150ms to 400ms overall delay.
