Abstract

A method of automatically backing up and restoring PIMS data stored in a mobile communication terminal is disclosed which allows the users of mobile communication terminals to conveniently restore previously maintained PIMS data in new mobile communication terminals without any loss of the data even when damage, loss or replacement of the mobile communication terminal occurs. To accomplish the above object, the invention encodes update-related information and user authentication information, transmits them to a PMIS data backup/restoration server while the user is not engaging in wireless communication, and stores them when the PIMS data of a user is updated in a mobile communication terminal.

Claims

1. A method of automatically backing up and restoring Personal Information Management System (PIMS) data of a mobile communication terminal, comprising the steps of:

providing a mobile communication terminal comprising an automatic PIMS data backup/restoration processor, a PIMS data backup/restoration protocol encoder/decoder, and a PIMS data transmission/reception unit, and a backup/restoration server of a service provider, comprising a PIMS data transmission/reception unit, a PIMS data backup/restoration protocol encoder/decoder, an automatic PIMS data backup/restoration processor and a PIMS data storage unit;

when user PIMS data is updated in the mobile communication terminal, encoding update-related data and user authentication information, transmitting them to the backup/restoration server while the user is not engaging in wireless communication, thereby storing them in the backup/restoration server; and

when a user request is made, encoding user authentication information, transmitting it to the backup/restoration server, receiving PIMS data of a corresponding user from the backup/restoration server after user authentication, and restoring and storing the PIMS data in the mobile communication terminal.

2. The method as set forth in claim 1, further comprising the steps of receiving and decoding the encoded information of the user, then determining whether the user is an authentic user based on the received authentication information, updating PIMS data of a corresponding user with corresponding data if the user request is a request for backup of PIMS data from a rightful user, and encoding PIMS data of the corresponding user and transmitting it to the corresponding user if the user request is a request for restoration of PIMS data from a rightful user.

3. The method as set forth in claim 1, wherein the backup and restoration of the PIMS data in the mobile communication terminal of a user comprises the steps of determining whether the PIMS data of the user has been updated;

automatically backing up the PIMS data if the PIMS data of the user has been updated;

determining whether a restoration request for the PIMS data has been made; and

restoring the PIMS data when the restoration request has been made.

4. The method as set forth in claim 1, wherein the backup of the PIMS data in the mobile communication terminal of a user comprises the steps of determining whether the user is currently carrying out data communication;

connecting the mobile communication terminal to the backup/restoration server when the user is not carring out data communication;

determining whether the connection is successful;

encoding the updated PIMS data and user authentication information and transmitting them to the backup/restoration server if the connection is successful; and

determining whether the transmission is successful.

5. The method as set forth in claim 1, wherein the restoration of the PIMS data in the mobile communication terminal of a user comprises the steps of acquiring user authentication information;

connecting the mobile communication terminal to the backup/restoration server and then encoding and transmitting the user authentication information;

receiving the restored data of the user; and

decoding the restored data and restoring PIMS data.

6. The method as set forth in claim 1, wherein the backup and restoration of the PIMS data in the backup/restoration server of a service provider comprises the steps of determining whether there has been a user request for backup or restoration of PIMS data;

receiving encoded user request data and decoding it if there has been the user request;

determining whether the user is an authentic user;

determining whether the user request is a request for restoration of PIMS data if the user is an authentic user;

acquiring user PIMS data from a database if the user request is a request for restoration of PIMS data;

encoding the acquired PIMS data and transmitting it to the user;

determining whether the user request is a request for backup of PIMS data; and

updating user PIMS data if the user request is a request for backup of PIMS data.
