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 for requesting data to synchronize transmits its head data to other party for synchronizing data through an Over-The-Air Function (OTAF) system. The party for synchronizing data compares the transmitted head data of the party requesting data to synchronize with its head data, and transmits its newest data and corresponding head data of the party for requesting data to synchronize to the party for requesting data to synchronize in accordance with the comparison result. The party for requesting data to synchronize stores the newest data from the party for requesting data, and transmits its newest data to the party 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 comprising the steps of:

transmitting, at either the mobile terminal or the computer corresponding to a party for requesting data to synchronize, its head data to other party for synchronizing data through an Over-The-Air Function (OTAF) system;

comparing, at the party for synchronizing data, the transmitted head data of the party requesting data to synchronize with its head data;

transmitting, at the party for synchronizing data, its newest data and a portion corresponding to newest data of the head data of the party for requesting data, in accordance with the comparison result, to the party for requesting data to synchronize through the OTAF;

storing the newest data of the party for synchronizing data in the party for requesting data to synchronize to transmit the newest data of the party for requesting data to synchronize to the party for synchronizing data through the OTAF; and

storing the transmitted newest data of the party for requesting data to synchronize in a memory area of the party for synchronizing data.

2. The method of

claim 1

, further comprising the step of transmitting a confirmation message to the party for requesting data to synchronize through the OTAF system after the step of storing the newest data of the party for requesting data to synchronize in the memory area of the party for synchronizing data.

3. The method of

claim 1

, wherein the party for requesting the data to synchronize is a mobile terminal, and the above steps are performed by pressing a synchronizing button of a schedule program on a key pad when a user of the mobile terminal uses a menu program of 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 by Internet network based on a TCP/IP.

5. A method for synchronizing data between a mobile terminal and a computer comprising the steps of:

transmitting, at either the mobile terminal or the computer corresponding to a party for requesting data to synchronize, its entire data to other party for synchronizing data through an OTAF system;

comparing, at the party for synchronizing data, head data of the transmitted data of the party requesting data to synchronize with its head data;

storing data having no provided in the party for synchronizing data, among the received data of the party for requesting data to synchronize in a memory area of the party for synchronizing data in accordance with the comparison result, while transmitting data of the party for synchronizing data, having no provided in the party for requesting data to synchronize, to the party for requesting data to synchronize through the OTAF system; and

storing the data transmitted from the party for synchronizing data in a memory area of the party for requesting data.

6. The method of

claim 5

, further comprising the step of transmitting a confirmation message to the party for requesting data to synchronize through the OTAF system after the step of storing the newest data of the party for requesting data to synchronize in the memory area of the party for synchronizing data.

7. The method of

claim 5

, wherein the party for requesting the data to synchronize is a mobile terminal, and the above steps are performed by pressing a synchronizing button of a schedule program on a key pad when a user of the mobile terminal uses a menu program of the mobile terminal.

8. The method of

claim 5

, 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 by Internet network based on a TCP/IP.

9. The method of

claim 5

, wherein the data which do not exist in the mobile terminal and the data which do not exist in the computer are respectively newest data of the computer and the mobile terminal.
