Abstract:
A mobile device for operation within a service provider's wide area wireless network system comprises a wireless communication system, a circuit switched application, and an IP application. The circuit switched application receives circuit switched call signaling from the wireless service provider network. The circuit switched call signaling comprises an MSISDN identifying the origin of a circuit switched call. The IP application determines whether the origin of the circuit switched call is capable of internet protocol communications by querying a contact database (or receiving an alert from the service provider network) to determine whether the MSISDN identifying the origin of the circuit switched call is associated with a unique uniform resource identifier. If the origin of the circuit switched call is capable of internet protocol communications, initiating an internet protocol communication thereto.
