Patent ID: 8223794

Claim:
A method for routing a call to a dual mode wireless device, the method comprising: receiving the call at a network node; receiving dual mode wireless device status information comprising a location of the dual mode wireless device, a strength of a signal received by the dual mode wireless device, and a cost associated with the call on a packet switched network and a circuit switched network; receiving network information for the packet switched network and the circuit switched network, the network information comprising a capacity and a coverage of the packet switched network and the circuit switched network in a particular area; selecting one of the packet switched network and the circuit switched network for use in connecting the call to the dual mode wireless device, the selecting designating a selected network and a non-selected network; routing the call to the dual mode wireless device via the selected network; and handing-off the call to the dual mode wireless device via the non-selected network during the call, the handing-off based on: a cost analysis including a comparison of a cost associated with the call on the non-selected network relative to a cost associated with the call on the selected network; the location of the dual mode wireless device; a data security preference; a coverage of each of the packet switched network and the circuit switched network; and a capacity of each of the packet switched network and the circuit switched network, the capacity based on information in a database and communication between the network node and the packet switched network and the circuit switched network.
