Abstract

The present disclosure includes a method and system for authenticating femtocell-connected mobile devices. In some implementations, a method includes receiving information associated with an authentication request transmitted by a cellular core network. The information is internetworked between a cellular radio technology and Session Initiation Protocol (SIP) for authenticating a cellular device in a femtocell.

Claims

1. A method, comprising:

receiving information associated with an authentication request transmitted by a cellular core network; and

internetworking the information between a cellular radio technology and Session Initiation Protocol (SIP) for authenticating a cellular device in a femtocell.

2. The method of claim 1, wherein the information comprises the authentication request.

3. The method of claim 2, wherein internetworking the information comprises mapping the authentication request to a SIP message for transmission through an Internet Protocol (IP) network.

4. The method of claim 3, wherein the SIP message comprises a SIP 40x message.

5. The method of claim 1, the information comprising a random number (RAND).

6. The method of claim 1, wherein the information comprises a signature response (SRES).

7. The method of claim 1, wherein receiving information associated with an authentication request comprises wirelessly receiving an authentication response from the cellular device the femtocell.

8. The method of claim 7, wherein internetworking the information comprises generating a SIP message based, at least in part, on the authentication response.

9. The method of claim 8, the SIP message comprising one of a SIP INVITE, a SIP SUBSCRIBE, a SIP NOTIFY, or a SIP REGISTER.

10. The method of claim 1, wherein the cellular radio technology comprises one of GSM, UMTS, WIMAX, WCDMA, EVDO, HSDPA, or CDMA.

11. The method of claim 1, wherein internetworking the information comprises encapsulating at least a portion of the information in a SIP message.

12. The method of claim 11, wherein the at least a portion is encapsulated in a MIME body.

13. A device, comprising:

a receiver configured to receive information associated with an authentication request transmitted by a cellular core network; and

a mapping module configured to internetwork the information between a cellular radio technology and Session Initiation Protocol (SIP) for authenticating a cellular device in a femtocell.

14. The device of claim 13, wherein the information comprises the authentication request.

15. The device of claim 14, wherein the mapping module configured to internetwork the information comprises the mapping module configured to map the authentication request to a SIP message for transmission through an Internet Protocol (IP) network.

16. The device of claim 15, wherein the SIP message comprises a SIP 40x message.

17. The device of claim 13, wherein the information comprises a random number (RAND).

18. The device of claim 13, wherein the information comprises a signature response (SRES).

19. The device of claim 13, wherein the receiver configured to receive information associated with an authentication request comprises the receiver configured to wirelessly receive an authentication response from the cellular device the femtocell.

20. The device of claim 19, wherein the mapping module configured to internetwork the information comprises the mapping module configured to generate a SIP message based, at least in part, on the authentication response.

21. The device of claim 20, wherein the SIP message comprises one of a SIP INVITE, a SIP SUBSCRIBE, a SIP NOTIFY, or a SIP REGISTER.

22. The device of claim 13, wherein the cellular radio technology comprises one of GSM, UMTS, WIMAX, WCDMA, EVDO, HSDPA, or CDMA.

23. The device of claim 13, wherein internetworking the information comprises encapsulating at least a portion of the information in a SIP message.

24. The device of claim 23, wherein the at least a portion is encapsulated in a MIME body.
