Abstract

A mobile device (10) and a corresponding method including a control module (10a) and a data store (10b) of digital rights in respect to optional capabilities, the data store (10b) having for each optional capability an enabled/disabled attribute indicating whether the optional capability is enabled in the device. The control module (10a) receives digital rights structure messages from an entity authorized to configure (or reconfigure) the device by changing the enabled/disabled attribute or by changing the information sufficient for the device to execute an optional capability. The data store (10b) also includes an on/off attribute for use by the owner of the device (10) for temporarily turning off an enabled optional capability, using a password.

Claims

1. A device (10) including at least one optional capability, the device (10) characterized by:

a control module (10a), responsive to a message providing an indicated change to a data store (10b) holding information on file indicating digital rights in respect to the at least one optional capability, for providing an update to the information on file corresponding to the indicated change provided by the message but only if the message is verified, the control module (10a) further responsive to a request from an application (10d) for access to the at least one optional capability, and for providing such access but only if such access is authorized by the information on file indicating digital rights in respect to the at least one optional capability; and

the data store (10b), for maintaining on file the information concerning the at least one optional capability, and for making available the information on file.

2. The device of claim 1, further characterized in that the information on file also includes an enabled/disabled attribute indicating whether the at least one optional capability is enabled or disabled, and in that the update to the information on file is a change to the enabled/disabled attribute of the at least one optional capability.

3. The device of claim 2, further characterized in that the enabled/disabled attribute has an associated parameter indicating a time period during which either the at least one optional capability is enabled or the at least one optional capability is disabled, or has an associated parameter indicating a remaining allowed number of uses of the at least one optional capability.

4. The device of claim 1, further characterized in that the information on file also includes an on/off attribute for controlling whether the at least one optional capability is temporarily unavailable, and in that the control module (10a) is further responsive to a message, accompanied by a password, indicating a change to the on/off attribute of the at least one optional capability, and also in that the update to the information on file is the change to the on/off attribute of the at least one optional capability.

5. The device of claim 4, further characterized in that the on/off attribute has an associated parameter indicating a time period during which either the at least one optional capability is on or the at least one optional capability is off, or has an associated parameter indicating a remaining allowed number of uses of the at least one optional capability.

6. The device of claim 1, further characterized in that the information on file includes code implementing the at least one optional capability or a pointer to code implementing the at least one optional capability, and the message includes a patch for patching the code implementing the at least one optional capability.

7. A system, including a device (10) as in claim 1 and a configuring module (12) for providing the message.

8. The system as in claim 7, further characterized in that the configuring module (12) communicates the message to the device (10) via a wireline (12a).

9. The system as in claim 7, further characterized in that the configuring module (12) communicates the message to the device (10) via wireless communication.

10. A system as in claim 9, also including a radio access network and further characterized in that the message is provided wirelessly via the radio access network.

11. A method (41) by which a device (10) is configured to disable or enable an optional capability provided with the device, the method characterized by:

a step (41a) of providing the device so as to include in a data store (10b) the optional capability, and an enabled/disabled attribute indicating whether the optional capability is enabled or disabled; and

a step (41d 41h) of updating the data store (10b), in response to a message, so as to change the attribute from disabled to enabled but only if the message is verified.

12. The method of claim 11, further characterized in that the enabled/disabled attribute has an associated parameter indicating a time period during which either the at least one optional capability is enabled or the at least one optional capability is disabled, or has an associated parameter indicating a remaining allowed number of uses of the at least one optional capability.

13. A method as in claim 11, further characterized by:

a step (41a) of providing the device so as to also include an on/off attribute and associated password for making available or making unavailable the optional capability provided that the optional capability is enabled, and so that the device executes the optional capability only if the on/off attribute is on; and

a step (41e) of changing the on/off attribute to off in response to a message to turn off the optional capability accompanied by a password, but only if the password accompanying the message agrees with the password associated with the on/off attribute provided with the device.

14. The method of claim 13, further characterized in that the on/off attribute has an associated parameter indicating a time period during which either the at least one optional capability is on or the at least one optional capability is off, or has an associated parameter indicating a remaining allowed number of uses of the at least one optional capability.
