Abstract

A system is disclosed in which a data processing device is completely synchronized with a messaging service. One embodiment of the system comprises a wireless data processing device; a messaging service to maintain messages and other information on behalf of a user; and synchronization logic for maintaining synchronization of the messages and other information between the wireless device and the messaging service.

Claims

1. A system comprising:

a messaging service to maintain a plurality of electronic mail (e-mail) messages on behalf of a user;

an interface to initiate wireless synchronization by transmitting one or more message updates upon the modification of one or more of the plurality of e-mail messages at the messaging service, and to assign an identification code to each of the e-mail messages upon generation; and

a wireless device, communicatively coupled to the interface, to initiate first synchronization with the messaging service by automatically transmitting a first message update to the messaging service via the interface as a modification occurs to a first e-mail message, to initiate second synchronization with the messaging service by automatically transmitting a second message update to the messaging service via the interface as a modification occurs to a second e-mail message, and to assign an identification code for the first and second e-mail messages upon generation, wherein each identification code is distinct from every other generated identification code.

2. The system of claim 1 wherein a new e-mail message generated at the messaging service application is assigned an identification code from within the first code range.

3. The system of claim 2 wherein the new e-mail message generated at the wireless device is assigned an identification code from within the second code range.

4. The system of claim 3 wherein all negative identification codes are assigned to the wireless device and all positive identification codes are assigned to the messaging service application.

5. The system of claim 3 wherein all negative identification codes are assigned to the messaging service application and all positive identification codes are assigned to the wireless device.

6. The system of claim 1 wherein each of the data transactions generated at the messaging service application is assigned a synchronization identification code (synch ID) upon generation indicating the sequence in which the data transactions were generated at the messaging service application.

7. The system of claim 6 wherein each of the data transactions generated at the wireless device are assigned a synch ID upon generation indicating the sequence in which the data transactions were generated at the wireless device.

8. The system of claim 7 wherein the server comprises mapping logic coupled to the messaging service application to map e-mail message identification codes to synch IDs.

9. The system of claim 1 wherein the server further comprises:

conflict detection logic, coupled to the messaging service application, to detect a conflict between a first version of an e-mail message stored at the messaging service application and a second version of the e-mail message received from the wireless device; and

conflict resolution logic, coupled to the conflict detection logic, to resolve the conflict between the first and second versions of the e-mail message.

10. The system of claim 1 wherein the wireless device comprises:

conflict detection logic to detect a conflict between the first version of the e-mail message stored at the wireless device and the second version of the e-mail message received from the messaging service application, and

conflict resolution logic, coupled to the conflict detection logic, to resolve the conflict between the first and second versions of the e-mail message.

11. A wireless device comprising:

logic to maintain a plurality of electronic messages (e-mails) and to first initiate synchronization with a server by automatically transmitting a first message update to the server as a modification occurs to a first e-mail message, to initiate second synchronization with the server by automatically transmitting a second message update to the server as a modification occurs to a second e-mail message, and to assign a distinct identification code for the first and second e-mails upon generation at the wireless device, wherein each identification code is distinct from every other generated identification code; and

conflict detection logic to detect conflicts between versions of e-mails stored at the wireless device and the second version of the e-mail message received from the server.

12. The wireless device of claim 11 wherein the interface further comprises conflict resolution logic, coupled to the conflict detection logic, to resolve the conflict between the versions of the e-mail message.

13. The wireless device of claim 11 wherein the range of e-mail identification codes generated at the server and the wireless device are divided in a manner that the server has a first code range and the wireless device has a second code range.

14. The wireless device of claim 13 wherein a new e-mail generated at the server is assigned an identification code from within the first code range and a new e-mail generated at the wireless device is assigned an identification code from within the second code range.

15. The wireless device of claim 14 wherein all negative identification codes are assigned to the wireless device and all positive identification codes are assigned to the server.

16. The wireless device of claim 14 wherein all negative identification codes are assigned to the server and all positive identification codes are assigned to the wireless device.

17. A system comprising:

a messaging service to maintain a plurality of electronic mail (e-mail) messages on behalf of a user;

an interface to initiate wireless synchronization by transmitting one or more message updates upon the modification of one or more of the plurality of e-mail messages at the messaging service, and to assign an identification code to each of the e-mail messages upon generation;

a data network coupled to the interface;

a data center communicatively coupled to the data network;

a wireless service provider network communicatively coupled to the data center; and

a wireless device to initiate first synchronization with the messaging service by automatically transmitting a first message update to the messaging service as a modification occurs to a first e-mail message, to initiate second synchronization with the messaging service by automatically transmitting a second message update to the messaging service via the interface as a modification occurs to a second e-mail message, and to assign an identification code for the first and second e-mail messages upon generation, wherein each identification code is distinct from every other generated identification code.

18. The system of claim 17 wherein a new e-mail message generated at the messaging service application is assigned an identification code from within the first code range.

19. The system of claim 17 wherein each of the data transactions generated at the messaging service application is assigned a synchronization identification code (synch ID) upon generation indicating the sequence in which the data transactions were generated at the messaging service application.

20. The system of claim 19 wherein each of the data transactions generated at the wireless device are assigned a synch ID upon generation indicating the sequence in which the data transactions were generated at the wireless device.

21. The system of claim 20 wherein the server comprises mapping logic coupled to the messaging service application to map e-mail message identification codes to synch IDs.
