Abstract

A processor (304) of a wireless communication device (102, 216) scans (806) a patch for any difference commands indicating that data submitted in this command has been differenced by a file-level difference based on a file extension. Memory (306) contains data representing a device management tree (DMT). The processor (304) updates data of the device management tree to provide dynamic update of the DMT to facilitate software updates based on the patch.

Claims

1. A wireless communication device comprising:

a transceiver configured to receive a first patch from a remote device;

a processor configured to scan the patch for any difference commands indicating that data submitted in this command has been differenced by a file-level difference based on a file extension; and

memory containing data representing a device management tree (DMT), the processor operative to update data representing a structure of the device management tree in response to receiving a DMT repair script to provide dynamic update of a DMT in response to software updates based on the first patch.

2. The wireless communication device of claim 1 wherein the first patch is delivered as part of an OSGi bundle and contains a directory referenced by a special entry in a bundle descriptor.

3. The wireless communication device of claim 1, wherein the processor resolves a difference command with a file-level process.

4. The wireless communication device of claim 3, wherein the processor converts the resolved difference commands to resolved change commands indicating a changed file.

5. The wireless communication device of claim 4, wherein the processor applies the first patch to a component of the device.

6. The wireless communication device of claim 5, wherein the processor searches for any same commands indicating an unchanged file, moves all unchanged files to a file system, adjusts data block pointers in a directory.

7. The wireless communication device of claim 6, wherein the processor moves data from the change commands to a target source, and adjusts the data block pointers in the directory.

8. The wireless communication device of claim 1 wherein the first patch contains a link to another source containing a second patch.

9. The wireless communication device of claim 8 wherein the processor obtains the second patch based on a uniform resource locator associated with the first patch.

10. A method for a wireless communication device comprising:

receiving a patch from a remote device; and

scanning the patch for any difference commands indicating that data submitted in this command has been differenced by a file-level difference based on a file extension;

updating data representing a structure of the device management tree in response to receiving a DMT repair script to provide dynamic update of a DMT in response to software updates based on the patch.

11. The method of claim 10, further comprising resolving a difference command with a file-level process.

12. The method of claim 11, further comprising converting the resolved difference commands to resolved change commands indicating a changed file.

13. The method of claim 12, further comprising applying the patch to a component of the wireless communication device.

14. The method of claim 13, further comprising:

searching for any same commands indicating an unchanged file;

moving all unchanged files to a file system; and

adjusting data block pointers in a directory.

15. The method of claim 14, further comprising:

moving data from the change commands to a target source; and

adjusting the data block pointers in the directory.

16. A wireless communication device comprising:

a transceiver configured to receive an OSGi bundle containing a first patch from a remote device;

memory containing a Linux operating system and containing data representing a device management tree (DMT);

a processor, operatively coupled to the memory and the transceiver, configured to use the Linux operating system and also scan the first patch for any difference commands indicating that data submitted in this command has been differenced by a file-level difference based on a file extension, the processor operative update data representing a structure of the device management tree in response to receiving a DMT repair script to provide dynamic update of a DMT in response to software updates based on the first patch.

17. The wireless communication device of claim 16 wherein the first patch contains a directory referenced by a special entry in a bundle descriptor.

18. The wireless communication device of claim 16, wherein the processor resolves a difference command with a file-level process.

19. The wireless communication device of claim 18, wherein the first patch contains a link to another source containing a second patch.

20. The wireless communication device of claim 19 wherein the processor obtains the second patch based on a uniform resource locator associated with the first patch.
