System and method for managing secure registration of a mobile communications device
View Patent ↗In one embodiment, a method is provided for managing secure registration of a mobile communications device, the method comprising registering, at a network node, the mobile communications device using a first registration process, the first registration process requiring an authentication key associated with the mobile communications device; processing a request from the mobile communications device, the request including an indication that the mobile communications device is changing to a second registration process; and clearing the authentication key associated with the mobile communications device upon expiration of a time window.
1. A method for managing secure registration of a mobile communications device, the method comprising:
registering, at a network node, the mobile communications device using a first registration process, the first registration process requiring an authentication key associated with the mobile communications device;
processing a request from the mobile communications device, the request including an indication that the mobile communications device is changing to a second registration process; and
clearing the authentication key associated with the mobile communications device upon expiration of a time window.
2. The method for managing secure registration of a mobile communications device as recited in claim 1 , wherein the network node is operable with a wireless packet data service network comprising one of a General Packet Radio Service [GPRS] network, an Enhanced Data Rates for Global System for Mobile Communications [GSM] Evolution [EDGE] network, a 3 rd Generation [3G] network, an Integrated Digital Enhanced Network [IDEN], a Code Division Multiple Access [CDMA] network and a Universal Mobile Telecommunications System [UMTS] network.
3. The method for managing secure registration of a mobile communications device as recited in claim 1 , wherein the first registration process effectuates an encryption scheme involving a request key with respect to registration requests received from the mobile communications device.
4. The method for managing secure registration of a mobile communications device as recited in claim 1 , wherein the first registration process effectuates an encryption scheme involving a response key with respect to registration responses sent to the mobile communications device.
5. The method for managing secure registration of a mobile communications device as recited in claim 1 , wherein the second registration process involves receiving unencrypted registration requests from the mobile communications device.
6. The method for managing secure registration of a mobile communications device as recited in claim 1 , wherein the second registration process involves sending unencrypted registration responses to the mobile communications device.
7. The method for managing secure registration of a mobile communications device as recited in claim 1 , wherein the time window is pre-defined.
8. The method for managing secure registration of a mobile communications device as recited in claim 1 , wherein the authentication key is mapped to a personalized indicium corresponding to the mobile communications device.
9. The method for managing secure registration of a mobile communications device as recited in claim 8 , wherein the personalized indicium comprises a Personal Information Number [PIN] that is bound to an identifier associated with the mobile communications device.
10. The method for managing secure registration of a mobile communications device as recited in claim 9 , wherein the identifier comprises at least one of an International Mobile station Equipment Identity [IMEI] parameter, an International Mobile Subscriber Identity [IMSI] parameter, an Electronic Serial Number [ESN] parameter and a Mobile Identification Number [MIN] parameter.
11. A network node, comprising:
means for registering a mobile communications device using a first registration process, the first registration process requiring an authentication key associated with the mobile communications device;
means for processing a request from the mobile communications device, the request including an indication that the mobile communications device is changing to a second registration process; and
means for clearing the authentication key associated with the mobile communications device upon expiration of a time window.
12. The network node as recited in claim 11 , wherein the first registration process effectuates an encryption scheme involving a request key with respect to registration requests received from the mobile communications device.
13. The network node as recited in claim 11 , wherein the first registration process effectuates an encryption scheme involving a response key with respect to registration responses sent to the mobile communications device.
14. The network node as recited in claim 11 , wherein the second registration process involves receiving unencrypted registration requests from the mobile communications device.
15. The network node as recited in claim 11 , wherein the second registration process involves sending unencrypted registration responses to the mobile communications device.
16. The network node as recited in claim 11 , wherein the time window is pre-defined.
17. The network node as recited in claim 11 , wherein the authentication key is mapped to a personalized indicium corresponding to the mobile communications device.
18. The network node as recited in claim 17 , wherein the personalized indicium comprises a Personal Information Number [PIN] that is bound to an identifier associated with the mobile communications device.
19. The network node as recited in claim 18 , wherein the identifier comprises at least one of an International Mobile station Equipment Identity [IMEI] parameter, an International Mobile Subscriber Identity [IMSI] parameter, an Electronic Serial Number [ESN] parameter and a Mobile Identification Number [MIN] parameter.
