First Claim
Patent Images
1. A method of generating a set of Mobile IP keys, comprising:
- obtaining an International Mobile Subscriber Identity;
generating at least one Mobile IP key from authentication information associated with the International Mobile Subscriber Identity; and
registering a Mobile Node supporting Mobile IP with a Home Agent supporting Mobile IP using the at least one Mobile IP key.

Abstract
Methods and apparatus for dynamically generating a set of Mobile IP keys are disclosed. The set of Mobile IP keys is dynamically generated using an existing HLR/AuC authentication infrastructure. This is accomplished, in part, by obtaining an International Mobile Subscriber Identity (IMSI) that uniquely identifies a particular Mobile Node. Once a set of Mobile IP keys is generated from authentication information associated with the IMSI, the Mobile Node may register with its Home Agent using the set of Mobile IP keys.

4. In a Mobile Node supporting Mobile IP, a method of registering with a Home Agent supporting Mobile IP, comprising:
-
sending a bootstrap request to the Home Agent to initiate generation of at least one Mobile IP key from the authentication information associated with an International Mobile Subscriber Identity;
receiving a bootstrap reply including one or more random numbers from the Home Agent; and
generating the at least one Mobile IP key from the authentication information associated with the International Mobile Subscriber Identity and the random numbers received in the bootstrap reply. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12)

13. In a Home Agent supporting Mobile IP, a method of registering a Mobile Node supporting Mobile IP with the Home Agent, comprising:
-
receiving a bootstrap request from the Mobile Node, the bootstrap request initiating generation of at least one Mobile IP key from authentication information associated with an International Mobile Subscriber Identity;
transmitting a bootstrap reply including one or more random numbers to the Mobile Node, thereby enabling the Mobile Node to generate the at least one Mobile IP key from the authentication information associated with the International Mobile Subscriber Identity and the random numbers; and
obtaining the at least one Mobile IP key, the at least one Mobile IP key being derived from the authentication information associated with the International Mobile Subscriber Identity and the random numbers. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 22)

23. In a AAA server, a method of generating at least one Mobile IP key, comprising:
-
receiving a request message from a Home Agent, the request message including an International Mobile Subscriber Identity;
transmitting a second request message including the IMSI to a Home Location Register;
receiving a reply message from the Home Location Register, the reply message including one or more random numbers and information derived from both the authentication information associated with the International Mobile Subscriber Identity and the random numbers; and
generating the at least one Mobile IP key from the information derived from both the authentication information associated with the International Mobile Subscriber Identity and the random number. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A Home Agent supporting Mobile IP and adapted for registering a Mobile Node supporting Mobile IP with the Home Agent, comprising:
-
means for receiving a bootstrap request from the Mobile Node, the bootstrap request initiating generation of at least one Mobile IP key from authentication information associated with an International Mobile Subscriber Identity;
means for transmitting a bootstrap reply including one or more random numbers to the Mobile Node, thereby enabling the Mobile Node to generate the at least one Mobile IP key from the authentication information associated with the International Mobile Subscriber Identity and the random numbers; and
means for obtaining the at least one Mobile IP key, the at least one Mobile IP key being derived from the authentication information associated with the International Mobile Subscriber Identity and the random numbers.

37. A Home Agent supporting Mobile IP and adapted for registering a Mobile Node supporting Mobile IP with the Home Agent, comprising:
-
a processor; and
a memory, at least one of the processor and the memory being adapted for;
receiving a bootstrap request from the Mobile Node, the bootstrap request initiating generation of at least one Mobile IP key from authentication information associated with an International Mobile Subscriber Identity;
transmitting a bootstrap reply including one or more random numbers to the Mobile Node, thereby enabling the Mobile Node to generate the at least one Mobile IP key from the authentication information associated with the International Mobile Subscriber Identity and the random numbers; and
obtaining the at least one Mobile IP key, the at least one Mobile IP key being derived from the authentication information associated with the International Mobile Subscriber Identity and the random numbers.
