Abstract

A method of administering network selections for a mobile station between a second generation/third generation wireless network and wireless local area networks includes detecting when the mobile station encounters a wireless area network, and communicating an identity of the encountered wireless area network to the second generation/third generation wireless network. The communicating prompts a query for permission to establish a session between the mobile station and the encountered wireless local area network. When permission is granted, the method includes receiving a key distributed to the mobile station. The key is used by the mobile station to establish a session between the mobile station and the encountered wireless local area network.

(b) communicating an identity of the encountered wireless area network to the second generation/third generation wireless network, said communicating prompting a query for permission to establish a session between the mobile station and the encountered wireless local area network; and

,

(c) when permission is granted, receiving a key distributed to the mobile station, said key being used by the mobile station to establish a session between the mobile station and the encountered wireless local area network.

2. The method of claim 1, wherein the communicating of step (b) is carried out over the second generation/third generation wireless network.

3. The method of claim 2, wherein the communicating of step (b) is directed to an authentication, authorization and accounting functional entity of the second generation/third generation wireless network.

4. The method of claim 3, wherein the authentication, authorization and accounting functional entity of the second generation/third generation wireless network is a home location register.

5. The method of claim 1, wherein the key is distributed over the encountered wireless local area network.

6. The method of claim 5, wherein the key is distributed from an authentication, authorization and accounting server of the encountered wireless local area network.

7. The method of claim 1, further comprising:

(d) informing the second generation/third generation wireless network when a session is established between the mobile station and the encountered wireless local area network.

8. The method of claim 1, wherein the query for permission is directed to the encountered wireless local area network from the second generation/third generation wireless network.

9. The method of claim 1, further comprising:

(e) maintaining user preferences which control the administering of network selections, said user preferences specifying at least one of;

a time, date or location restriction outside of which the mobile station is not to be handed-off to a wireless local area network;

which wireless local area networks the mobile station can be handed-off to;

which wireless local area network to favor when more than one wireless local area network is available; and

, a hand-off transparency for a wireless local area network.

10. The method of claim 1, further comprising:

(e) maintaining provider preferences which control the administering of network selections, said provider preferences specifying at least one of;

a time, date or location restriction outside of which the mobile station is not to be handed-off to a wireless local area network;

which wireless local area networks the mobile station can be handed-off to;

which wireless local area network to favor when more than one wireless local area network is available; and

, a hand-off transparency for a wireless local area network.

11. The method of claim 10, further comprising:

(f) receiving the provider preferences over the second generation/third generation wireless network from at least one of a service provider employing the second generation/third generation wireless network, and an operator of the second generation/third generation wireless network.

12. The method of claim 11, wherein provider preferences are dynamically updated to reflect changes therein.

21. The client of claim 12, further comprising:

means for administering shifted data transfers including at least one of shift-in-time data transfers and shift-in-space data transfers.

22. The client of claim 21, wherein the means for administering shifted data transfers includes means for accessing a database in which orders for shifted data transfers are maintained.

13. A client which administers network selections of a mobile communications device between a second generation/third generation wireless network and wireless local area networks, said client comprising:

means for detecting when the mobile station encounters a wireless area network;

means for communicating an identity of the encountered wireless area network to the second generation/third generation wireless network, said communicating prompting a query for permission to establish a session between the mobile station and the encountered wireless local area network; and

,

means for receiving a key distributed to the mobile station when permission is granted, said key being used by the mobile station to establish a session between the mobile station and the encountered wireless local area network.

14. The client of claim 13, wherein the client runs on the mobile communications device.

15. The client of claim 14, wherein the mobile communications device is one of a personal digital assistant, a mobile phone, or a laptop computer.

16. The client of claim 14, wherein the mobile communications device includes:

,

a second interface which selectively provides a wireless connection to the wireless local area networks.

17. The client of claim 16, wherein the first interface is a wireless modem, and the second interface is a wireless PC card.

18. The client of claim 13, further comprising:

means for maintaining user preferences which control the administering of network selections, said user preferences specifying at least one of;

a time, date or location restriction outside of which the mobile station is not to be handed-off to a wireless local area network;

which wireless local area networks the mobile station can be handed-off to;
