Abstract
The disclosure is directed to a mobile communication device that is capable of accessing different types of networks such as a circuit-switched network and a packet-switched network. When supplementary services are invoked involving the device, a protocol is used that signals between the device and a central server that maintains the state information for the supplementary services. In this way, hand-over between the two different types of networks may occur without interrupting supplementary services.
