Abstract

A method and apparatus for efficient data storage and management in order to reduce battery consumption in a mobile device are disclosed. Two data stores, an unorganized store and an organized store, are provided in the mobile device. The unorganized store stores a data in as-it-arrives basis. The organized store stores data in a way that is more efficient for data search and retrieval. A controller controls the unorganized store and the organized store such that new data is stored in the unorganized store while the mobile device is battery powered and moved to the organized store while the mobile device is powered by an external power source. The data is retrieved from the organized store once the data is moved to the organized store.

Claims

1. A method for efficient data storage and management in a mobile device, the method comprising:

providing an unorganized store and an organized store;

storing data in the unorganized store when the mobile device is battery powered; and

moving the data stored in the unorganized store to the organized store during a period when the mobile device is powered by an external power source, the organized store storing the data in an efficient way for data search and retrieval, whereby battery power consumption of the mobile device is reduced.

2. The method of claim 1 wherein the data is stored in the unorganized store in an as-it-arrives basis.

3. The method of claim 1 wherein the data is stored in a compressed format in the unorganized store.

4. The method of claim 3 wherein the data is stored in a decompressed format in the organized store.

5. The method of claim 1 wherein the organized store is organized by a plurality of substores.

6. The method of claim 5 wherein the substores are user independent.

7. The method of claim 5 further comprising:

analyzing content of the data before storing the data in the organized store, whereby the data is stored in one of the substores based on the content of the data.

8. The method of claim 5 wherein a metadata is attached to the data based on the content of the data before storing the data in the organized store.

9. The method of claim 8 wherein a sharing right of the data is included in the metadata.

10. The method of claim 8 wherein a metadata format is uniform in the same substore.

11. The method of claim 8 wherein the metadata provides at least one linked list comprising pointers for linking data stored in the organized store in accordance with a key word.

12. The method of claim 8 wherein when data is deleted from the organized store, only an access flag in the metadata for the data is modified to mark the data inaccessible and pointers in the linked list are updated accordingly.

13. The method of claim 8 wherein the linked lists are formed in an alphabetical order.

14. The method of claim 1 further comprising:

receiving a query for a data;

determining whether the queried data is stored in the organized store;

retrieving the queried data from the organized store if the queried data is found in the organized store; and

retrieving the queried data from the unorganized store if the queried data is not found in the organized store.

15. The method of claim 14 further comprising:

determining a substore for the queried data;

if the substore is found in a data management registry, retrieving the queried data in the substore; and

if the substore is not found in the data management registry, retrieving the queried data from the unorganized store.

16. The method of claim 1 wherein the data is stored in the organized store without fragmentation.

17. The method of claim 1 wherein the organized store includes an encrypted folder for storing encrypted data.

18. A mobile device for efficient data storage and management, the mobile device comprising:

an unorganized store for storing data;

an organized store for storing data in a way that is more efficient for data search and data retrieval; and

a controller for controlling data storage and retrieval such that data is stored in the unorganized store while the mobile device is battery powered and the data stored in the unorganized store is moved to the organized store while the mobile device is powered by an external power source.

19. The mobile device of claim 18 wherein the data is stored in the unorganized store in an as-it-arrives basis.

20. The mobile device of claim 18 wherein the data is stored in a compressed format in the unorganized store.

21. The mobile device of claim 20 wherein the data is stored in a decompressed format in the organized store.

22. The mobile device of claim 18 wherein the organized store is organized by a plurality of substores.

23. The mobile device of claim 22 wherein the substores are user independent.

24. The mobile device of claim 22 wherein the controller analyzes content of the data before storing the data in the organized store, whereby the data is stored in one of the substores based on the content of the data.

25. The mobile device of claim 22 wherein the controller attaches a metadata to the data based on the content of the data before storing the data in the organized store.

26. The mobile device of claim 25 wherein a sharing right of the data is included in the metadata.

27. The mobile device of claim 25 wherein a metadata format is uniform in the same substore.

28. The mobile device of claim 25 wherein the metadata provides at least one linked list comprising pointers for linking data stored in the organized store in accordance with a key word.

29. The mobile device of claim 28 wherein the linked lists are formed in an alphabetical order.

30. The mobile device of claim 28 wherein the controller provides a soft hyperlink based on the linked list.

31. The mobile device of claim 25 wherein when data is deleted from the organized store, the controller modifies an access flag in the metadata for the data to mark the data inaccessible and updates pointers in the linked list accordingly.

32. The mobile device of claim 18 wherein the controller retrieves queried data from the organized store if the queried data is found in the organized store and retrieves the queried data from the unorganized store if the queried data is not found in the organized store.

33. The mobile device of claim 32 wherein the controller retrieves the queried data in the substore if a substore for the queried data is found in a data management registry and retrieves the queried data from the unorganized store if the substore for the queried data is not found in the data management registry.

34. The mobile device of claim 18 wherein the data is stored in the organized store without fragmentation.

35. The mobile device of claim 18 wherein the organized store includes an encrypted folder for storing encrypted data.

36. The mobile device of claim 18 wherein the controller provides an abstraction function to make the stores transparent to an application.
