Abstract

Profile information of mobile terminal devices of users is synchronized by transmitting profile information of a user of a mobile terminal device along with a group identification information to a profile information synchronization server, registering by the server received profile information in correspondence with received group identification information, based upon the transmitting, extracting by the server one or more of the profile information managed based upon the received group identification information of the group to which the user of the terminal device belongs including new profile information that the terminal device has not recorded and transmitting the extracted profile information to the terminal device. The terminal device obtains the profile information of the group to which the user of the terminal device belongs including the new profile information that the terminal device itself has not recorded, from the server based upon the group identification information.

Claims

1. A profile information synchronization system, comprising:

a plurality of mobile terminal devices; and

a profile information synchronization server in communication with the plurality of mobile terminal devices and comprising;

a profile information storage unit storing profile information of a user registered by the mobile terminal device for each group identification information identifying a group of users exchanging the profile information between the mobile terminal devices, and

a controller

storing in the profile information storage unit profile information of the user received from the mobile terminal device in correspondence to the group identification information,

extracting, based upon the group identification information, one or more of the profile information of the group to which the user of the mobile terminal device belongs including new profile information that the mobile terminal device has not recorded, from the profile information storage unit, and

transmitting the extracted profile information to the mobile terminal device,

wherein the mobile terminal devices comprises a controller

transmitting the profile information of the user of the mobile terminal device along with the group identification information to the profile information synchronization server;

obtaining from the profile information synchronization server the extracted profile information of the group to which the user of the mobile terminal device belongs including the new profile information that the mobile terminal device itself has not recorded, based upon the group identification information; and

recording the obtained profile information.

2. The profile information synchronization system according to claim 1, wherein the obtaining of the profile information by the mobile terminal device comprises automatically accessing the profile information synchronization server at intervals of a predetermined time and obtaining the profile information of the group to which the user belongs including the new profile information, based upon the group identification information.

3. A method synchronizing profile information of mobile terminal devices of users, comprising:

transmitting profile information of a user of a mobile terminal device along with a group identification information to a profile information synchronization server;

registering by the profile information synchronization server received profile information in correspondence with received group identification information, based upon the transmitting;

extracting by the profile information synchronization server one or more of the profile information managed based upon the received group identification information of the group to which the user of the mobile terminal device belongs including new profile information that the mobile terminal device has not recorded and transmitting the extracted profile information to the mobile terminal device; and

obtaining by the mobile terminal device the profile information of the group to which the user of the mobile terminal device belongs including the new profile information that the mobile terminal device itself has not recorded, from the profile information synchronization server based upon the group identification information.

4. The profile information synchronization method according to claim 3, wherein the obtaining of the profile information by the mobile terminal device comprises automatically accessing the profile information synchronization server at intervals of a predetermined time and obtaining the profile information of the group to which the user belongs including the new profile information, based upon the group identification information.

8. The method according to claim 3, further comprising prompting, by the mobile terminal device, user input of the group identification information.

5. A mobile terminal device in communication with a profile information synchronization server having a profile information storage device storing profile information of a user registered by the mobile terminal device according to group identification information identifying a group of users exchanging the profile information between mobile terminal devices, comprising:

a management unit transmitting the profile information of the user of the mobile terminal device to the profile information synchronization server along with the group identification information for registration by the profile information synchronization server storing the profile information of the user of the mobile terminal device received with the group identification information in correspondence with the group identification information for management;

an obtaining unit receiving the profile information of the group to which the user of the mobile terminal device belongs from the profile information synchronization server including new profile information that the mobile terminal device itself has not recorded; and

a storage unit storing the obtained profile information.

6. The mobile terminal device according to claim 5, wherein the obtaining unit obtaining the profile information of the mobile terminal device automatically accesses the profile information synchronization server at intervals of a predetermined time and obtains the profile information of the group to which the user belongs including the new profile information that the mobile terminal device itself has not recorded, from the profile information managed by the profile information synchronization server based upon the group identification information.

7. A profile information synchronization server in communication with a plurality of mobile terminal devices having a storage unit storing profile information, comprising:

a profile information storage device storing profile information of a user registered by a mobile terminal device according to group identification information identifying a group of users exchanging the profile information between the mobile terminal devices,

a management unit receiving the profile information of the user with the group identification information from the mobile terminal device, and storing the received profile information in the profile information storage device in correspondence to the group identification information;

a transmitting unit extracting, from the profile information storage device, one or more of the profile information managed based upon the group identification information of the group to which the user of the mobile terminal device belongs including new profile information that the mobile terminal device has not recorded, and transmitting the extracted profile information to the mobile terminal device.
