AUTHENTICATING FEMTOCELL-CONNECTED MOBILE DEVICES
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.
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.
