Estimating the term…
The hybrid mobile terminal is engaged in an existing call through a serving one of a circuit switched or packet data wireless networks. The mobile terminal places a new call through the target one of the wireless networks, the new call having a predetermined called party identifier. In response to the called party identifier, the call is converted to a loop-back call directed to the mobile terminal through the serving wireless network, establishing a call path through the target wireless network. The mobile terminal accepts the loop-back call, and directs the existing call to connect to the call path through the target wireless network. The existing call through the original network is then dropped, effecting an inter-system handoff from the serving to the target wireless network.
A method of hand off from a serving one of a packet data or circuit switched wireless network to a target one of the networks, for a hybrid mobile terminal capable of communications through both networks and engaged in an existing call through the serving wireless networks, comprising:
A method of handing off a hybrid mobile terminal, operative to communicate through both packet data and circuit switched wireless networks, from a serving one of such networks initially carrying an existing call to a target one of such networks, comprising:
A circuit switched wireless network, comprising:
A packet data wireless network, comprising:
