Abstract

Methods and devices for allowing a wireless communication device (1301) initially unauthorized for communication with a network to obtain persistent soft network subscription credential information (1303) from a wireless communication device (1401) initially authorized for communication with the network are disclosed. In performing the persistent transfer of the soft network subscription credential information (1303), one of a token management module (1312), a session initiation protocol communication module (1408), or a electronic rights manager (1406) may be used to ensure that only one communication device is capable of communicating with a network at any one time.

Claims

1. A method in a wireless communication device initially unauthorized for communication with a network for obtaining persistent soft network subscription credentials from a wireless communication device initially authorized for communication with the network, the method comprising the steps of:

detecting an absence of the soft network subscription credentials in the wireless communication device initially unauthorized for communication with the network;

electronically searching for the wireless communication device initially authorized for communication with the network;

initiating a request for a persistent transfer of the soft network subscription credentials by transmitting an activation request to the wireless communication device initially authorized for communication with the network; and

upon the wireless communication device initially authorized for communication with the network deactivating its communication authorization, receiving a soft network subscription credentials from the wireless communication device initially authorized for communication with the network.

2. The method of claim 1, further comprising the step of authorizing the wireless communication device initially unauthorized for communication with the network to communicate with the network.

3. The method of claim 1, wherein the soft network subscription credentials comprise information capable of identifying a network associated with a service provider.

4. The method of claim 1, wherein the soft network subscription credentials comprise a user identification module.

5. The method of claim 4, wherein the user identification module comprises a subscriber identification module.

6. The method of claim 4, wherein the user identification module comprises an international mobile equipment identifier.

7. The method of claim 4, wherein the user identification module comprises an international mobile subscriber identification.

8. The method of claim 7, wherein at least a portion of the international mobile subscriber identification comprises a home public land mobile network identifier.

9. The method of claim 1, wherein the step of transmitting the activation request comprises transmitting a device identifier associated with the wireless communication device initially unauthorized for communication with the network.

10. The method of claim 9, wherein the device identifier comprises one if an international mobile equipment identifier or a secure electronic certificate.

11. The method of claim 1, further comprising the step of initiating an authentication process with the network.

12. The method of claim 11, wherein the authentication process comprises an authentication and key agreement process.

13. The method of claim 1, further comprising the step of receiving an acknowledgement message from the wireless communication device initially authorized for communication with the network in response to the step of transmitting the activation request.

14. The method of claim 13, further comprising the step of activating a network interface configured for electronic communication with the network.

15. The method of claim 1, further comprising the step of receiving an activation token from the wireless communication device initially authorized for communication with the network in response to the step of transmitting the activation request.

16. The method of claim 15, further comprising the step of transmitting an activation token removal confirmation request to the wireless communication device initially authorized for communication with the network.

17. The method of claim 16, further comprising the step of receiving an activation token removal confirmation in response to the step of transmitting the activation token removal confirmation request.

18. The method of claim 17, further comprising the step of activating a network interface configured to communicate with the network.

19. A method in a wireless communication device initially authorized for communication with a network for a transfer of soft network subscription credentials to a wireless communication device initially unauthorized for communication with the network, the method comprising the steps of:

receiving a request for the soft network subscription credentials, the request comprising an activation request, from the wireless communication device initially unauthorized for communication with the network;

immutably deactivating an authorization for communication with the network; and

after deactivating the authorization for communication with the network, transmitting a soft network subscription credentials

to the wireless communication device initially unauthorized for communication with the network.

20. The method of claim 19, further comprising the step of transmitting an electronic message comprising the activation request to a service provider.

21. The method of claim 20, further comprising the step of receiving an electronic rights management key from the service provider.

22. The method of claim 21, further comprising the step of transmitting an acknowledgement to the service provider upon completing the step of receiving the electronic rights management key.

23. The method of claim 19, wherein the step of transmitting the soft network subscription credentials comprises transmitting an electronic rights management key.

24. The method of claim 20, wherein the step of transmitting the electronic message comprising the activation request comprises transmitting a session initiation protocol REGISTER message having the activation request stored therein.

25. The method of claim 24, further comprising the step of receiving a session initiation protocol message from the service provider.

26. The method of claim 25, wherein the session initiation protocol message comprises a 200 OK message.

27. The method of claim 25, further comprising the step of transmitting a session initiation protocol acknowledgement to the service provider.

28. The method of claim 27, further comprising the step of transmitting an activation complete message to the wireless communication device initially unauthorized for communication with the network upon immutably deactivating the authorization for communication with the network.

29. The method of claim 19, further comprising the step of transmitting an acknowledgement to the wireless communication device initially unauthorized for communication with the network in response to receiving the request for the soft network subscription credentials.

30. The method of claim 29, further comprising the step of deactivating a network interface in the wireless communication device initially authorized to communicate with the network.

31. The method of claim 29, further comprising the step of immutably deleting a network credential activation token in the wireless communication device initially authorized to communicate with the network.

32. The method of claim 31, further comprising the step of transmitting an activation token removal confirmation to the wireless communication device initially unauthorized for communication with the network.

33. A soft network subscription credential transfer module in a wireless communication device, comprising:
