Abstract

A system, method and computer program product are provided for efficiently updating a scanning subsystem of a mobile communication device. Initially received is a first portion of an update adapted for updating a scanning subsystem of a mobile communication device. Further, more portions of the update are received in addition to the receipt of the first portion of the update. The update is then installed with the scanning subsystem.

Claims

1. A method for efficiently updating a scanning subsystem of a mobile communication device, comprising:

receiving a first portion of an update adapted for updating a scanning subsystem of a mobile communication device;

receiving additional portions of the update in addition to the receipt of the first portion of the update; and

installing the update with the scanning subsystem.

2. The method of claim 1, and further comprising determining an integrity of the update.

3. The method of claim 2, wherein the update is installed with the scanning subsystem, if the integrity of the update is verified.

4. The method of claim 2, wherein the integrity of the update is determined utilizing a signature.

5. The method of claim 4, wherein the signature is received with one of the portions of the update.

6. The method of claim 4, wherein the signature is compared against another signature generated utilizing each of the portions of the update.

7. The method of claim 4, wherein the signature is received only with a last one of the additional portions of the update.

8. The method of claim 1, wherein a size of the portions of the update is minimized.

9. The method of claim 1, wherein the portions of the update are compressed.

10. The method of claim 1, and further comprising determining whether the first portion is empty.

11. The method of claim 10, wherein the additional portions of the update are conditionally received based on whether it is determined that the first portion is empty.

12. The method of claim 1, and further comprising pausing scanning utilizing the scanning subsystem.

13. The method of claim 12, and further comprising resuming the scanning utilizing the scanning subsystem upon the update being installed with the scanning subsystem.

14. The method of claim 1, wherein the update is requested by the mobile communication device.

15. The method of claim 14, wherein the update is requested by the mobile communication device utilizing a request data structure.

16. The method of claim 15, wherein the request data structure includes variables selected from the group consisting of a uniform resource locator (URL) variable, a mobile communication identifier variable, an application program interface version variable, a detection logic variable, a signature version variable, and a portion number variable.

17. The method of claim 15, wherein the request data structure includes variables selected from the group including a uniform resource locator (URL) variable, a mobile communication identifier variable, an application program interface version variable, a detection logic variable, a signature version variable, and a portion number variable.

18. The method of claim 1, wherein each portion of the update includes a header.

19. The method of claim 18, wherein the header indicates an identifier of the associated portion of the update.

20. The method of claim 18, wherein the header indicates a length of the associated portion of the update.

21. The method of claim 1, wherein the mobile communication device includes a cellular telephone.

22. A computer program product for efficiently updating a scanning subsystem of a mobile communication device, comprising:

computer code for receiving a first portion of an update adapted for updating a scanning subsystem of a mobile communication device;

computer code for receiving additional portions of the update in addition to the receipt of the first portion of the update; and

computer code for installing the update with the scanning subsystem.

23. A system for efficiently updating a scanning subsystem of a mobile communication device, comprising:

a backend server; and

a mobile communication device in wireless communication with the backend server for receiving therefrom a first portion of an update adapted for updating a scanning subsystem of the mobile communication device, receiving additional portions of the update in addition to the receipt of the first portion of the update, and installing the update with the scanning subsystem.

24. A method for efficiently updating a scanning subsystem of a mobile communication device utilizing a backend server, comprising:

sending a first portion of an update adapted for updating a scanning subsystem of a mobile communication device; and

sending additional portions of the update in addition to the first portion of the update;

wherein the update is installed with the scanning subsystem of the mobile communication device.

25. A method for updating a scanning subsystem of a mobile communication device, comprising:

sending a request for an update adapted for updating a scanning subsystem of a mobile communication device;

receiving a first portion of the update in response to the request;

determining whether the first portion is empty;

if it is determined that the first portion is not empty, receiving additional portions of the update in addition to the receipt of the first portion of the update;

verifying a signature associated with the update;

pausing scanning utilizing the scanning subsystem;

installing the update with the scanning subsystem, if the signature is verified; and

resuming the scanning utilizing the scanning subsystem upon the update being installed with the scanning subsystem.
