Abstract
The invention provides a telecommunication system that allows communication between a circuit-based wireless telephony network and a packet-based Internet telephony network without requiring access to the Public Switched Telephone Network. The system includes a circuit-based wireless telephony network providing wireless access to the system, a packet-based Internet telephony network providing Internet telephony access to the system, and a base station gateway controller for providing an interface between the wireless telephony network and the Internet telephony network. The invention further provides methods for facilitating communication between a first device, the first device being a packet-based Internet telephony network based device, and a second device, the second device being a circuit-based wireless telephony network based device, by facilitating connection of a call from the first device to the second device, without requiring access to the public switched telephone network.

22. A method for facilitating communication between a first device, the first device being a packet-based Internet telephony network based device, and a second device, the second device being a circuit-based wireless telephony network based device, by facilitating connection of a call from the first device to the second device, the method comprising:
-
receiving, at a home Session Initiation Protocol proxy server associated with the first device, an invite to connect the call;
the home Session Initiation Protocol proxy server determining a Mobile Station ISDN associated with the second device;
utilizing a Home Location Register to map the mobile station ISDN to a Mobile Station Routing Number associated with the second device;
utilizing an Enum database to map the Mobile Station Routing Number to a Session Initiation Protocol address associated with a serving mobile switching center associated with the second device; and
utilizing the Session Initiation Protocol address in connecting the call. - View Dependent Claims (23, 24, 25, 26, 28, 29, 30, 31, 32)
