Claims
- 1. A method, comprising:
using credential information stored in a subscriber identity module (SIM) associated with a General Packet Radio Service (GPRS) adapter to authenticate access to a wireless local area network (WLAN), wherein communications with the SIM is carried out using extensible authentication protocol (EAP).
- 2. The method of claim 1, further comprising
issuing one or more requests via a smart card interface to get the credential information.
- 3. The method of claim 2, further comprising:
arbitrating the one or more requests to the SIM when the SIM is busy.
- 4. The method of claim 3, wherein the one or more requests are received by the SIM via a SIM reader driver.
- 5. The method of claim 4, further comprising:
receiving the credential information from the SIM after the one or more requests are processed by the SIM.
- 6. The method of claim 1, further comprising:
establishing a WLAN connection with the WLAN via a WLAN adapter.
- 7. The method of claim 6, wherein the WLAN connection is established while there is a connection to a GPRS network via the GPRS adapter.
- 8. The method of claim 7, further comprising:
issuing a location update to switch data services from the GPRS network to the WLAN; and disconnecting from the GPRS network.
- 9. A machine-readable medium including machine readable instructions that, if executed by a computer system, cause the computer system to perform a method comprising:
using credential information stored in a subscriber identity module (SIM) associated with a General Packet Radio Service (GPRS) adapter to authenticate access to a wireless local area network (WLAN), wherein communications with the SIM is carried out using extensible authentication protocol (EAP).
- 10. The machine-readable medium of claim 9, further comprising
issuing one or more requests via a smart card interface to get the credential information.
- 11. The machine-readable medium of claim 10, further comprising:
arbitrating the one or more requests to the SIM when the SIM is busy.
- 12. The machine-readable medium of claim 11, wherein the one or more requests are received by the SIM via a SIM reader driver.
- 13. The machine-readable medium of claim 12, further comprising:
receiving the credential information from the SIM after the one or more requests are processed by the SIM.
- 14. The machine-readable medium of claim 9, further comprising:
establishing a WLAN connection with the WLAN via a WLAN adapter.
- 15. The machine-readable medium of claim 14, wherein the WLAN connection is established while there is a connection to a GPRS network via the GPRS adapter.
- 16. The machine-readable medium of claim 15, further comprising:
issuing a location update to switch data services from the GPRS network to the WLAN; and disconnecting from the GPRS network.
- 17. A system, comprising:
a wireless local area network (WLAN) adapter; a general packet radio service (GPRS) adapter coupled to the WLAN adapter and including a subscriber identify module (SIM); and a mobility client to initiate requests for credential information from the SIM to authenticate access to a WLAN when the mobility recognizes an access point, wherein said requests for the credential information are communicated to the SIM using extensible authentication protocol (EAP).
- 18. The system of claim 17, wherein the requests for the credential information are communicated to the SIM via a smart card interface.
- 19. The system of claim 18, wherein the requests for the credential information are received by the SIM via a SIM reader driver.
- 20. The system of claim 19, wherein the GPRS adapter includes a SIM access module (SAM) to arbitrate the request for the credential information to the SIM.
- 21. The system of claim 20, wherein the SAM arbitrates the requests for the credential information to the SIM while there is a GPRS connection to a GPRS network via the GPRS adapter.
- 22. The system of claim 21, wherein the mobility client is further to issue a location update after the access to the WLAN is authenticated and a WLAN connection is established.
- 23. The system of claim 22, wherein the mobility client is further to drop the GPRS connection.
- 25. The system of claim 17, wherein the WLAN adapter and the GPRS adapter are installed an open platform.
- 26. The system of claim 17, wherein the WLAN adapter and the GPRS adapter are combined into one module.
- 27. A system, comprising:
means for initiating requests for credential information from a subscriber identity module (SIM) associated with a general packet radio service (GPRS) adapter; means for authenticating access to a wireless local area network (WLAN) using the credential information; and means for switching data services from a GPRS connection to a WLAN connection after the access to the WLAN is authenticated.
- 28. The system of claim 27, wherein said means for requesting the credential information from the SIM includes means for arbitrating requests to the SIM.
- 29. The system of claim 28, wherein said means for switching data services between the GPRS connection and the WLAN connection includes means for performing a location update.
- 30. The system of claim 27, further comprising:
means for interfacing with the SIM to send the request for the credential information.
