Abstract

A method for synchronizing data between a mobile terminal and a computer is provided, in which schedule data can be synchronized between the mobile terminal and the computer using a radio network and Internet network. In this method, either a mobile terminal or a computer corresponding to a party requesting data to synchronize transmits its head data to another party for synchronizing data through an Over-The-Air Function (OTAF) system. The party synchronizing data compares the transmitted head data with its head data, and transmits its newest data and corresponding head data in accordance with the comparison result. The requesting party stores the newest data, and transmits its newest data to the parry for synchronizing data through the OTAF system. Then, the party for synchronizing data stores the newest data of the party for requesting data to synchronize in its memory area.

Claims

1. A method for synchronizing data between a mobile terminal and a computer, each of the mobile terminal and the computer alternately a first party and a second party, the method comprising:

(a) transmitting a call message from the first party to an Over-The-Air Function (OTAF) system;

(b) transmitting a request message from the OTAF system to the first party;

(c) transmitting a first response message including head data from the first party to the OTAF system;

(d) transmitting the first response message from the OTAF system to the second party;

(e) comparing, by the second party, the transmitted head data of the first party with head data of the second party;

(f) transmitting request data including newest data and a portion corresponding to newest data of the head data of the second party, in accordance with a result of said comparing, to the OTAF system;

(g) transmitting the request data from the OTAF system to the first party;

(h) storing the newest data of the second party in a memory of the first party;

(i) transmitting a second response message including the newest data of the first party to the OTAF system;

(j) transmitting the second response message from the OTAF system to the second party; and

(k) storing the transmitted newest data of the first party in a memory of the second party.

2. The method of claim 1, further comprising transmitting a confirmation message to the first party through the OTAF system.

3. The method of claim 1, wherein the first party is a mobile terminal, and the step (a) is performed by pressing a synchronizing button on the mobile terminal.

4. The method of claim 1, wherein the mobile terminal and the OTAF system are connected with each other through a radio network, and the OTAF system and the computer are connected with each other via the Internet.

16. The method of claim 1, wherein transmissions of data between the mobile terminal and the OTAF system comprise an over-the-air service provisioning (OTASP) message.

5. A method for synchronizing data between a mobile terminal and a computer, each of the mobile terminal and the computer selectively a first party and a second party, the method comprising:

(a) transmitting a call message from the first party to an over-the-air-function (OTAF) system;

(b) transmitting a request message from the OTAF system to the first party;

(c) transmitting a response message from the first party to the OTAF system, wherein the response message includes substantially an entire data of the first party;

(d) transmitting the response message from the OTAF system to the second party;

(e) comparing, at the second party, head data from the first party with head data of the second party;

(f) storing data not previously existing in the second party according to the comparison;

(g) transmitting request data including data of the second party not previously existing in the transmitted substantially entire data, from the second party to the the OTAF system;

(h) transmitting the request data from the OTAF system to the first party; and

(i) storing the data transmitted from the second party in a memory of the first party.

6. The method of claim 5, further comprising transmitting a confirmation message to the first party through the OTAF system.

7. The method of claim 5, wherein the first party is a mobile terminal, and the step (a) is performed by pressing a synchronizing button on the mobile terminal.

8. The method of claim 5, wherein the mobile terminal and the OTAF system are connected via a radio network, and the OTAF system and the computer are connected with each other via the Internet.

9. The method of claim 5, wherein the data not previously existing in the mobile terminal and the data not previously existing in the computer are respectively newest data of the computer and the mobile terminal.

17. The method of claim 5, wherein at least one transmission between the mobile terminal and the OTAF system includes an over-the-air service provisioning (OTASP) message.

10. A system for synchronizing data comprising:

a mobile terminal;

a computer; and

an OTAF provider which allows communication between the mobile terminal via radio and to the computer by a network connection for synchronizing data between said mobile terminal and said computer, wherein each of the mobile terminal and the computer are configured to initiate a synchronization request, and wherein each of the mobile terminal and the OTAF provider are adapted to send and receive an over-the-air service provisioning (OTASP) message, wherein the mobile terminal and the computer, being selectively a first party and a second party, with the OTAF provider are configured to transmit a call message from the first party to the OTAF provider, transmit a request message from the OTAF provider to the first party, transmit a first response message including head data from the first party to the OTAF provider, transmit the first response message from the OTAF provider to the second party, compare, by the second party, the transmitted head data of the first party with head data of the second party, transmit request data including newest data and a portion corresponding to newest data of the head data of the second party, in accordance with a result of said compare to the OTAF provider, transmit the request data from the OTAF provider to the first party, store the newest data of the second party in a memory of the first party, transmit a second response message including the newest data of the first party to the OTAF provider, transmit the second response message from the OTAF provider to the second party, and store the transmitted newest data of the first party in a memory of the second party.

11. The system of claim 10, wherein the mobile terminal is equipped to perform data synchronization with the computer by transmitting a request, head data and data to the OTAF.

12. The system of claim 10, wherein the OTAF is equipped to transmit a request, head data from the mobile terminal, and data to be synchronized to the computer via the network connection.

13. The system of claim 10, wherein the OTAF is equipped to transmit a request, head data from the computer, and data to be synchronized to the mobile terminal via radio.

14. The system of claim 10, wherein the mobile terminal further comprises a button which issues a request for synchronization to the OTAF.

15. The system of claim 10, wherein the OTAF further comprises means for issuing a confirmation code to the mobile terminal after successful synchronization.
