Abstract: A method is provided of transferring a call connection with a mobile terminal from a first network to a second network. The first network is capable of handling both circuit-switched and packet-switched modes of connection. The second network is capable of handling one of the packet-switched or circuit-switched modes of connection but not both. The terminal is capable of both packet-switched and circuit-switched call modes of connection. The method comprises the first network: identifying the location of the mobile terminal with respect to at least one of the networks, identifying the mobile terminal as being in a mode of connection not usable in the second network, instructing the mobile terminal to transfer the call connection to the other mode of connection, and transferring the call connection to the second network.

Abstract: The present invention provides methods involving at least one mobile unit configured to receive wireless connectivity using first and second wireless communication systems that operate according to first and second radio interface technologies, respectively. The first and second radio interface technologies are different. The method may include determining, in response to the mobile unit handing off from the first to the second wireless communication system, session establishment information for the second wireless communication system based on session establishment information associated with the first wireless communication system.

Abstract: The present invention provides a method of operating an idle mobile unit that is capable of communicating with first and second wireless communication systems. One embodiment of the method includes providing a location update message in response to the idle mobile unit transitioning from a first tracking area associated with the second wireless communication system to a second tracking area associated with the second wireless communication system. The first and second wireless communication systems are capable of paging the idle mobile unit following the location update message.
