Abstract

A server for integrating an unlicensed wireless communication system and a licensed wireless communication system includes a network interface card, a licensed wireless network interface card, and a processor connected to the network interface card and the licensed wireless network interface card. A memory is connected to the processor. The memory stores instructions to identify when a subscriber device is entering a service region of a selected unlicensed wireless communication base station. Additional instructions coordinate the routing of a current communication session on a licensed wireless communication system to the selected unlicensed wireless communication base station.

Claims

1. A server for integrating an unlicensed wireless communication system and a licensed wireless communication system, comprising:

a network interface card;

a licensed wireless network interface card;

a processor connected to said network interface card and said licensed wireless network interface card; and

a memory connected to said processor, said memory storing

instructions to identify when a subscriber device is entering or leaving a service region of a selected unlicensed wireless communication base station, and

instructions to transfer the routing of a current communication session between a licensed wireless communication system and said selected unlicensed wireless communication base station.

2. The server of claim 1 wherein said memory stores instructions to process a licensed wireless authentication request from said selected unlicensed wireless communication base station.

3. The server of claim 2 wherein said memory stores instructions to route said licensed wireless authentication request to a home location register.

4. The server of claim 3 wherein said memory stores instructions to pass licensed wireless communication system security information from said home location register to said unlicensed wireless communication base station.

5. The server of claim 4 wherein said memory stores instructions to compare an authentication result produced by a subscriber device associated with said unlicensed wireless communication base station to an authentication value received from an adjacent mobile switch center.

6. The server of claim 5 wherein said memory stores instructions to produce an authentication command when said authentication result matches said authentication value, thereby allowing the transition of said current communication session between said licensed wireless communication system and said selected unlicensed wireless communication base station.

7. The server of claim 1 wherein said memory includes instructions to receive a service profile from a provisioning server.

8. The server of claim 7 wherein said memory includes instructions to compare said service profile with information received from said unlicensed wireless communication base station to selectively complete the provisioning of said unlicensed wireless communication base station.

9. The server of claim 8 wherein said memory includes instructions to deliver information about a subscriber device associated with said unlicensed wireless communication base station to a home location register for said subscriber device.

10. The server of claim 1, wherein said memory stores instructions to emulate a mobile switching center to facilitate said transfer.

11. A network node, comprising:

a network interface card configured to receive subscriber device location information from a network connected to an unlicensed wireless service region;

a licensed wireless network interface card configured to communicate with a licensed wireless network; and

a processor connected to said network interface card and said licensed wireless network interface card, said processor utilizing said subscriber device location information to generate control signals for said licensed wireless network interface card, said control signals initiating the transition of a wireless communication session from a first wireless system to a second wireless system, wherein said first wireless system is selected from the group including a licensed wireless system and an unlicensed wireless system, and said second wireless system is the unselected system from said group including a licensed wireless system and an unlicensed wireless system.

12. The network node of claim 11 further comprising a memory connected to said processor, said memory storing instructions to process a licensed wireless authentication request from a selected unlicensed wireless communication base station of said unlicensed wireless service region.

13. The network node of claim 12 wherein said memory stores instructions to route said licensed wireless authentication request to a home location register.

14. The network node of claim 13 wherein said memory stores instructions to pass licensed wireless communication system security information from said home location register to said unlicensed wireless communication base station.

15. The network node of claim 14 wherein said memory stores instructions to compare an authentication result produced by a subscriber device associated with said unlicensed wireless communication base station to an authentication value received from an adjacent mobile switch center.

16. The network node of claim 15 wherein said memory stores instructions to produce an authentication command when said authentication result matches said authentication value, thereby allowing said transition.

17. The network node of claim 11 further comprising a memory connected to said processor, wherein said memory includes instructions to receive a service profile from a provisioning server.

18. The network node of claim 17 wherein said memory includes instructions to compare said service profile with information received from an unlicensed wireless communication base station to selectively complete the provisioning of said unlicensed wireless communication base station.

19. The network node of claim 18 wherein said memory includes instructions to deliver information about a subscriber device associated with said unlicensed wireless communication base station to a home location register for said subscriber device.

20. The network node of claim 11 further comprising a memory connected to said processor, said memory storing instructions to emulate a mobile switching center to facilitate said transition.

21. A method of integrating an unlicensed wireless communication system and a licensed wireless communication system, comprising:

identifying when a subscriber device is entering or leaving a service region of a selected unlicensed wireless communication base station; and

transferring the routing of a current communication session between a licensed wireless communication system and said selected unlicensed wireless communication base station.

22. The method of claim 21 further comprising processing a licensed wireless authentication request from said selected unlicensed wireless communication base station.

23. The method of claim 22 further comprising routing said licensed wireless authentication request to a home location register.

24. The method of claim 23 further comprising passing licensed wireless communication system security information from said home location register to said unlicensed wireless communication base station.

25. The method of claim 24 further comprising comparing an authentication result produced by a subscriber device associated with said unlicensed wireless communication base station to an authentication value received from an adjacent mobile switch center.

26. The method of claim 25 further comprising producing an authentication command when said authentication result matches said authentication value, thereby allowing the transition of said current communication session between said licensed wireless communication system and said selected unlicensed wireless communication base station.

27. The method of claim 21 further comprising receiving a service profile from a provisioning server.

28. The method of claim 27 further comprising comparing said service profile with information received from said unlicensed wireless communication base station to selectively complete the provisioning of said unlicensed wireless communication base station.

29. The method of claim 28 further comprising delivering information about a subscriber device associated with said unlicensed wireless communication base station to a home location register for said subscriber device.
