Abstract

A system for synchronizing information comprises a plurality of mobile communication devices storing individually incomplete user information, and at least one mobile service interface adapted to receive and transmit the stored user information for processing. The information synchronization system also comprises at least one processor adapted to arrange the transmitted user information to allow each mobile communication device to complete its user information without data duplication. The processor transmits the arranged user information to each mobile communication device via the mobile service interface for storage therein.

Claims

1. An information synchronization system, comprising:

a plurality of mobile terminals, each of the mobile terminals adapted to store telephone number data organized in a group and to transmit the group to a mobile service interface, wherein the group in at least one of the mobile terminals is missing telephone number data that is in the group of at least one of the other mobile terminals;

at least one mobile service interface adapted to receive the telephone number data groups from each of the mobile terminals, to combine the telephone number data and to transmit the combined telephone number data for processing; and

at least one processor adapted to receive the combined telephone number data, to arrange the combined telephone number data for each of the mobile terminals to include only the telephone number data that is missing from the group for each of the respective mobile terminals, and to transmit the arranged telephone number data to each of the mobile terminals by way of said at least one mobile service interface,

wherein, each of the mobile terminals is adapted to store the arranged telephone number data in the group,

when the arranged telephone number data is stored in the group of each of the mobile terminals, the group in all of the mobile terminals is synchronized without duplication of telephone number data in the group in any of the mobile terminals,

each of said plurality of mobile terminals and said at least one processor are capable of long message service (LMS) messaging with said at least one mobile service interface, and

said at least one mobile service interface is a long message service center (LMSC).

2. The information synchronization system of claim 1, wherein said at least one processor is a web server.

3. A method for synchronizing information, comprising:

providing a plurality of mobile terminals, each of the mobile terminals adapted to store telephone number data organized in a group, wherein the group in at least one of the mobile terminals is missing telephone number data that is in the group of at least one of the other mobile terminals;

providing at least one mobile service interface;

transmitting the telephone number data group from each of the mobile terminals to the at least one mobile service interface;

combining the telephone number data in the at least one mobile service interface;

providing at least one processor;

transmitting the combined telephone number data from the at least one mobile service interface to the at least one processor;

arranging the combined telephone number data for each of the mobile terminals using the at least one processor to include only the telephone number data that is missing from the group for each of the respective mobile terminals;

transmitting the arranged telephone number data for each of the mobile terminals from the at least one processor to the at least one mobile service interface;

transmitting the respective arranged telephone number data from the at least one mobile service interface to each of the mobile terminals; and

storing the respective arranged telephone number data in each of the mobile terminals,

wherein, when the arranged telephone number data is stored in each of the mobile terminals, the telephone number data group is synchronized between all of the mobile terminals without duplication of telephone number data in the group in any of the mobile terminals,

each of said plurality of mobile terminals and said at least one processor are capable of long message service (LMS) messaging with said at least one mobile service interface, and

said at least one mobile service interface is a long message service center (LMSC).

4. The information synchronization method of claim 3, wherein said at least one processor is a web server.
