Abstract

The present invention provides a method involving a femtocell in communication with a secure network. The method includes determining whether the femtocell is authorized to provide wireless connectivity to a mobile unit based on information stored in a secure entity in the secure network. The information has been confirmed by a user of the mobile unit.

Claims

1. A method involving a femtocell in communication with a secure network, comprising:

determining whether the femtocell is authorized to provide wireless connectivity to a mobile unit based on information stored in a secure entity in the secure network, said information having been confirmed by a user of the mobile unit.

2. The method of claim 1, wherein determining whether the femtocell is authorized to provide wireless connectivity to the mobile unit comprises determining whether the femtocell is authorized to provide wireless connectivity to the mobile unit based on a list of mobile units associated with the femtocell.

3. The method of claim 2, comprising modifying the list of mobile units associated with the femtocell to add or remove the mobile unit if the user of the mobile unit confirms the additional or removal.

4. The method of claim 3, comprising receiving a confirmation of the addition or removal from the user of the mobile unit via at least one of the mobile unit, the femtocell, or an interface provided by the secure entity.

5. The method of claim 4 comprising providing, to the user of the mobile unit, information indicating an attempt to add or remove the mobile unit from the list of mobile units associated with the femtocell, and wherein receiving the confirmation provided by the user of the mobile unit comprises receiving the confirmation in response to providing the information indicating the attempt to add or remove the mobile unit from the list of mobile units associated with the femtocell.

6. The method of claim 4, wherein receiving the confirmation of the addition or removal from the user of the mobile unit comprises receiving secret information known only to the user and the security entity.

7. The method of claim 1, further comprising:

receiving a request from the femtocell to modify the information stored in the secure entity to add or remove the mobile unit, the request including a femtocell identifier; and

validating the identifier associated with the femtocell.

8. The method of claim 7, further comprising granting the request and modifying the information stored in the secure entity when the identifier is validated.

9. The method of claim 8, wherein further comprising denying the request and not modifying the information stored in the secure entity when the identifier is not validated.

10. A method of operating a femtocell in communication with a secure network, comprising:

providing, from the femtocell to a secure entity in the secure network, a request to provide wireless connectivity to a mobile unit; and

receiving permission to provide wireless connectivity to the mobile unit when information stored in the secure entity in the secure network indicates that a user of the mobile unit has confirmed that the femtocell is authorized to provide wireless connectivity to the mobile unit.

11. The method of claim 10, wherein providing the request to provide wireless connectivity to the mobile unit comprises providing a request to modify a list of mobile units associated with the femtocell to add or remove the mobile unit such that the list is modified if the user of the mobile unit confirms the additional or removal.

12. The method of claim 11, wherein providing the request to provide wireless connectivity to the mobile unit comprises providing a femtocell identifier, and wherein receiving permission to provide wireless connectivity to the mobile unit comprises receiving permission in response to the secure entity validating the femtocell identifier.

13. The method of claim 11, wherein providing the request to provide wireless connectivity to the mobile unit comprises:

providing, to the mobile unit, a request to add the mobile unit to the list of mobile units associated with the femtocell;

receiving, from the mobile unit, information indicating whether the mobile unit confirms addition to the list of mobile units associated with the femtocell; and

providing, to the secure entity, the information indicating whether the mobile unit confirms addition to the list of mobile units associated with the femtocell.

14. The method of claim 13, wherein receiving permission to provide wireless connectivity to the mobile unit comprises receiving permission to provide wireless connectivity to the mobile unit when the provided information indicates that the mobile unit confirms addition to the list of mobile units associated with the femtocell.

15. The method of claim 13, wherein receiving information indicating whether the mobile unit confirms addition to the list of mobile units comprises receiving secret information known only to the user of the mobile unit and the secure entity.

16. A method of operating a mobile unit, the method involving a femtocell in communication with a secure network, comprising:

providing, from the mobile unit to a secure entity in the secure network, information indicating whether the femtocell is authorized to provide wireless connectivity to the mobile unit.

17. The method of claim 16, comprising receiving, at the mobile unit, information indicating an attempt to add or remove the mobile unit from a list of mobile units associated with the femtocell.

18. The method of claim 17, wherein providing the information indicating whether the femtocell is authorized to provide wireless connectivity to the mobile unit comprises providing the information in response to receiving the information indicating the attempt to add or remove the mobile unit from the list of mobile units associated with the femtocell.

19. The method of claim 18, wherein providing the information indicating whether the femtocell is authorized to provide wireless connectivity to the mobile unit comprises providing secret information known only to the user and the secure entity.
