Abstract

A resource efficient content management and delivery system includes a pack manager (120) and one or more loadable packs (114). The pack manager (120) provides the control for the loading and unloading of packs from memory, such as flash memory (112) or any other nonvolatile memory. The pack manager (120) also keeps a master pointer table (304) which is used to access the different packs (114) loaded into radio (100). The content download method using the pack method of the present invention provides much needed flexibility and a potential reduction of memory requirements, since data can be downloaded into the radio (100) very easily and the technique can Execute in Place (XIP) which is not supported by prior art FDI file techniques. The data provided by packs (114) does not require the radio (100) to be powered off and on in order to use the data, making the content download system very useful for numerous applications.

Claims

1. A method for registering at least one pack comprising an image file in a radio communication device having a pack manager, comprising the steps of:

initializing the pack manager;

determining if the radio communication device has a pack loaded that comprises an image file; and

if a pack is loaded, using an error checker in the pack manager to determine if the pack is valid or invalid.

2. A method as defined in claim 1, wherein if at least one valid pack is loaded in the radio communication device, the method further comprises:

registering the at least one pack with the pack manager, the pack manager having a master pointer table that points to a location of the at least one pack in a memory of the device.

3. A method as defined in claim 2, further comprising the step of:

updating the master pointer table when a new pack is loaded into the radio communication device.

4. A method as defined in claim 3, further comprising the step of:

flagging the at least one pack loaded into the radio communication device by the pack manager as ready for runtime access if it is determined to be valid.

5. A method as defined in claim 1, wherein the pack manager includes a pack loader, a master pointer table and an error checker.

6. A method as defined in claim 1, wherein the at least one pack is loaded into nonvolatile memory located in the radio communication device.

7. A method as defined in claim 6, wherein the at least one pack can be loaded and read without power recycling the radio communication device.

8. A method as defined in claim 1, further comprising the step of:

determining a type of pack that may be loaded in the radio communication device by the pack manger reading a unique identifier located in the pack.
