Abstract: Session switching or session transfer across devices has become a common feature in today's telecommunication world, given that a single user could easily own more than one device. However, most of the systems in the literature are designed for homogeneous network, i.e. switching session within a common network such as across only IP devices. In this paper, we design a prototype to support session switching across devices in different network, which is from IP to Public Switch Telephone Network (PSTN) and vice versa. Our prototype is built on top of an IP Multimedia Subsystem (IMS) to leverage on its standard convergence interface with media gateway. Experimental results shown that our session transfer took an extra of 0.31 second more than the IP-to-IP session switching. © 2012 IEEE.
