Wireless network gateway
First Claim
1. A network gateway, comprising:
- an identification database including one or more mobile unit entries, where each mobile unit entry indicates a subscriber information database storing subscriber information for the mobile unit corresponding to the mobile unit entry;
a subscriber information database including one or more subscriber entries, where each subscriber entry indicates for a corresponding mobile unit a location, a status, and any services subscribed to by the corresponding mobile unit;
an identifier table including an identifier entry for each subscriber entry in the subscriber information database, where each identifier entry indicates a correspondence between a first identifier and a second identifier;
a primary network connection connected to a first wireless network, where the first wireless network is a packet switched network; and
a secondary network connection connected to second wireless network.

Abstract
Methods and apparatus for implementing a network gateway that links two or more wireless networks, such as a packet switched network and a circuit switched network. In one implementation, a network gateway includes: an identification database including one or more mobile unit entries, where each mobile unit entry indicates a subscriber information database storing subscriber information for the mobile unit corresponding to the mobile unit entry; a subscriber information database including one or more subscriber entries, where each subscriber entry indicates for a corresponding mobile unit a location, a status, and any services subscribed to by the corresponding mobile unit; an identifier table including an identifier entry for each subscriber entry in the subscriber information database, where each identifier entry indicates a correspondence between a first identifier and a second identifier; a primary network connection connected to a first wireless network, where the first wireless network is a packet switched network; and a secondary network connection connected to second wireless network.

10. A method of providing subscriber information for a mobile unit subscribed to a primary network roaming in a secondary network, comprising:
-
receiving a request at a gateway in a primary network for subscriber information for a mobile unit from a secondary network, where the request includes a first identifier indicating the mobile unit;
converting the first identifier to a second identifier;
retrieving subscriber information using the second identifier; and
providing a response from the gateway to the secondary network, where the response includes the retrieved subscriber information and the first identifier. - View Dependent Claims (11, 12, 13, 14)

15. A method of sending data from a mobile unit through a wireless circuit switched network, comprising:
-
receiving data from a mobile unit at a base station in a wireless circuit switched network, where the data indicates a destination for the data, a requested data transmission service, and an identifier corresponding to the mobile unit, and where the mobile unit is a subscriber in a wireless packet switched network;
sending the data from the base station to a mobile switching center;
retrieving subscriber information corresponding to the identifier from a subscriber information database in the wireless packet switched network, where the subscriber information indicates permitted services for the mobile unit;
comparing the destination and requested data transmission service with the subscriber information;
if the destination is accessible through an external packet switched network connected to the wireless packet switched network, sending the data to the external packet switched network through a router; and
if the destination is accessible through an external circuit switched network connected to the wireless packet switched network, sending the data to the external circuit switched network through an exchange switch. - View Dependent Claims (16, 17, 18, 19, 20)

21. A method of sending data to a mobile unit through a wireless packet switched network and a wireless circuit switched network, comprising:
-
receiving data from an external network in a wireless packet switched network, where the data includes an identifier corresponding to a mobile unit;
retrieving status information corresponding to the identifier from a subscriber information database, where the status information indicates the mobile unit is registered in a wireless circuit switched network;
requesting a temporary local directory number from the wireless circuit switched network;
sending the data and the temporary local directory number to an exchange switch; and
sending the data from the exchange switch to the wireless circuit switched network using the temporary local directory number. - View Dependent Claims (22, 23, 24, 25, 26, 27)

28. A system for providing subscriber information for a mobile unit subscribed to a primary network roaming in a secondary network, comprising:
-
means for receiving a request at a gateway in a primary network for subscriber information for a mobile unit from a secondary network, where the request includes a first identifier indicating the mobile unit;
means for converting the first identifier to a second identifier;
means for retrieving subscriber information using the second identifier; and
means for providing a response from the gateway to the secondary network, where the response includes the retrieved subscriber information and the first identifier.
