Abstract

A wireless local area network (WLAN) communication system that includes an access point in communication with a mobile station and at least one Authentication, Authorization, and Accounting (AAA) server provides an authentication process whereby a user of the mobile station may select a WLAN service provider from among one or more WLAN service providers and/or one or more 3GPP service providers before being authenticated and further to make a decision to subscribe to the services of the selected service provider based on network service information, other than or in addition to an Service Set Identifier (SSID), associated with the selected service provider.

Claims

1. A method for providing network service information to a user of a mobile station accessing a wireless local area network comprising:

receiving a request to authenticate the mobile station; and

in response to receiving the request, conveying network identification and service information with respect to each service provider of a plurality of service providers to the mobile station.

2. The method of claim 1, wherein the request to authenticate the mobile station and the network identification and service information are each conveyed in a medium access control layer message.

3. The method of claim 2, wherein the request to authenticate the mobile station comprises an Extensible Application Protocol Over Lan-Start message and the network service information is conveyed in an Extensible Application Protocol Over Lan-Extensible Application Protocol-Request/Information message.

4. The method of claim 1, further comprising:

requesting authentication information; and

receiving the requested authentication information from the mobile station.

5. The method of claim 4, wherein receiving the requested authentication information comprises receiving a selection of a service provider from among the plurality of service providers.

6. The method of claim 4, wherein medium access control layer messages are used to request the authentication information and to receive the requested authentication information.

7. The method of claim 6, wherein the authentication information is requested in an Extensible Application Protocol Over Lan-Extensible Application Protocol-Request/Identity message and the requested authentication information is received in an Extensible Application Protocol Over Lan-Extensible Application Protocol-Response/Identity message.

8. The method of claim 4, further comprising requesting authorization of the mobile station.

9. The method of claim 4, further comprising:

determining an Authentication, Authorization, and Accounting server based on the received authentication information; and

requesting authorization of the mobile station by the determined Authentication, Authorization, and Accounting server.

10. A method for accessing a wireless local area network comprising:

conveying a request to authenticate a mobile station;

receiving network identification and service information with respect to a service provider; and

determining whether to access the wireless local area network based on the received network identification and service information.

11. The method of claim 10, further comprising:

displaying at least a portion of the received network identification and service information to the user of the mobile station; and

in response to displaying the at least a portion of the received network identification and service information, receiving an indication of a desire to access the wireless local area network.

12. The method of claim 10, wherein determining comprises determining whether to access the wireless local area network based on the received network identification and service information and further based on stored preferences.

13. The method of claim 10, wherein the request to authenticate the mobile station and the network identification and service information are each conveyed in a medium access control layer message.

14. The method of claim 13, wherein the request to authenticate the mobile station comprises an Extensible Application Protocol Over Lan-Start message and the network service information is conveyed in an Extensible Application Protocol Over Lan-Extensible Application Protocol-Request/Information message.

15. The method of claim 10, further comprising:

receiving a request for authentication information; and

conveying the requested authentication information.

16. The method of claim 15, wherein receiving network identification and service information with respect to a service provider comprises receiving network identification and service information with respect to each service provider of a plurality of service providers and wherein conveying the requested authentication information comprises conveying a selection of a service provider from among the plurality of service providers.

17. The method of claim 15, wherein medium access control layer messages are used to request the authentication information and to convey the requested authentication information.

18. The method of claim 17, wherein the authentication information is requested in an Extensible Application Protocol Over Lan-Extensible Application Protocol-Request/Identity message and the requested authentication information is conveyed in an Extensible Application Protocol Over Lan-Extensible Application Protocol-Response/Identity message.

19. The method of claim 15, further comprising receiving authorization to convey data traffic to the wireless local area network.

20. An Access Point in a wireless local area network comprising:

a memory that stores an identifier and network service information in association with each service provider of a plurality of service providers; and

a processor coupled to the memory that assembles one or more messages comprising the service provider identifier and the network service information associated with each service provider of a plurality of service providers and conveys the one or more messages to a mobile station.

21. The Access Point of claim 20, wherein the one or more messages comprise medium access layer messages.

22. The Access Point of claim 20, wherein the processor receives a request to authenticate the mobile station and, in response to receiving the request, assembles the one or more messages.

23. The Access Point of claim 22, wherein the one or more messages comprises a first one or more messages and wherein the processor further assembles a second message comprising a request for authentication information and conveys the second message to the mobile station.

24. The Access Point of claim 23, wherein the processor further, in response to conveying the request for authentication information, receives the requested authentication information and, in response to receiving the requested authentication information, assembles a third message requesting authorization of the mobile station and conveys the third message to a server.

25. The Access Point of claim 24, wherein the memory further stores, in association with the server, a service provider identifier, wherein the received authentication information comprises the service provider identifier, and wherein the processor determines the server based on the received service provider identifier.
