Abstract

A mobile device configured to communicate with one or more various enterprise services and Internet services. Such services include such features as e-mail, calendar, and personal information management (PIM). The mobile device is configured to maintain a distinction between each of these services by having a number of databases, each database dedicated to a specific service. To facilitate this distinction, a service identifier is generated with respect to each database. When a service is removed, the mobile device no longer has access to the service. In such an instance, the mobile device is configured to maintain the associated database and the service identifier. Should a removed service become reactivated for the mobile device, the maintained database will become re-associated with the proper service by using the service identifier. By distinguishing between databases using the service identifiers, the mobile device may prevent “cross-pollination” between its databases when synchronizing with different services.

Claims

1. A method of managing data items within a mobile communication device, the data items being organized into a plurality of data collections stored in a storage of the mobile communication device, the mobile communication device being in communication with a remote service of a server over a wireless network, one collection in the plurality of collections being in association with the remote service, the method comprising:

receiving service information relating to the remote service from the server;

storing the received service information in the storage;

generating an identifier representing the association using the received service information;

removing the remote service from the mobile communication device including deleting the service information from the storage; and

maintaining the collection and the identifier within the storage when the remote service is removed.

2. A method as claimed in claim 1, further including the step of removing access to the collection from applications operating on the mobile communication device.

3. A method as claimed in claim 1, further comprising:

reactivating the remote service to the mobile communication device; and

re-associating the collection with the remote service using the identifier.

4. A method as claimed in claim 3, further comprising, after re-associating, synchronizing at least some of the data items in the maintained collection with the server associated with the remote service.

5. A method as claimed in claim 1, wherein the storage includes a second collection in the plurality of collections being in association with a second remote service of a second server.

6. A method as claimed in claim 5, wherein data items include categorization within categories of information, and wherein the remote services include applications having common functions as between the remote services and wherein such applications access data items within common categories of information.

7. A method as claimed in claim 6, wherein data items are organized into the plurality of collections based on association with one of the remote services independent of the particular category of information.

8. A method as claimed in claim 7, wherein the categories of information include information relating to personal information.

9. A method as claimed in claim 1, wherein the service information includes service records, and the step of generating includes extracting specified information from the service records.

10. A method as claimed in claim 1, wherein the storage is a persistent memory and the collection stored therein is a data persistent database.

11. A method as claimed in claim 1, wherein the identifier is generated from hashing at least one of an identifier of a user, an identifier of a data source, and an identifier of the remote service.

23. A method as claimed in claim 5, further comprising displaying, when the remote service is removed, a combined view of data from the maintained collection and data from the second collection of the plurality of data collections.

12. A mobile communication device, comprising:

a controller for controlling the operation of the device;

a communication subsystem connected to the controller configured for data communication with a remote service of a server over a wireless network;

a storage for storage of data items, the data items being organized into a plurality of data collections stored in the storage, one collection in the plurality of collections being in association with the remote service;

the controller being configured for receiving service information relating to the remote service from the server, storing the received service information in the storage, generating an identifier representing the association using the received service information, removing the remote service from the mobile communication device including deleting the service information from the storage, and maintaining the collection and the identifier within the storage when the remote service is removed.

13. A mobile communication device as claimed in claim 12, wherein the controller is further configured for removing access to the collection from applications operating on the mobile communication device.

14. A mobile communication device as claimed in claim 12, wherein the controller is further configured for:

reactivating the remote service to the mobile communication device; and

re-associating the collection with the service using the identifier.

15. A mobile communication device as claimed in claim 14, wherein the controller is further configured for, after re-associating, synchronizing at least some of the data items in the maintained collection with the server associated with the remote service.

16. A mobile communication device as claimed in claim 12, wherein data items include categorization within categories of information, and wherein the remote services include applications having common functions as between the remote services and wherein such applications access data items within common categories of information.

17. A mobile communication device as claimed in claim 12, wherein the storage includes a second collection in the plurality of collections being in association with a second remote service of a second server.

18. A mobile communication device as claimed in claim 17, wherein data items are organized into the plurality of collections based on association with one of the services independent of the particular category of information.

19. A mobile communication device as claimed in claim 18, wherein the categories of information include information relating to personal information.

20. A mobile communication device as claimed in claim 12, wherein the storage is a persistent memory and the collection stored therein is a data persistent database.

21. A mobile communication device as claimed in claim 12, wherein the identifier is generated from hashing at least one of an identifier of a user, an identifier of a data source, and an identifier of the remote service.

22. A mobile communication device as claimed in claim 12, wherein the mobile communication device is a handheld device.
