First Claim
1. A wireless communication terminal synchronization method in which data stored in a memory in each of plural wireless communication terminals is synchronized with each other, when a user selectively utilizes the plural wireless communication terminals by using a single subscriber information card, at least communicating operation in each of the wireless communication terminals being enabled by mounting thereon the subscriber information card that records subscriber information, the method comprising the steps of:
- uploading from a first wireless communication terminal with the subscriber information card being mounted, to a server via a communication network, updated part of data which is stored in a memory in the first wireless communication terminal, in accordance with a user'"'"'s request or automatically, said uploading being performed with only data updated after the subscriber information card was mounted on the first wireless communication terminal, while leaving the uploaded data in the memory in the first wireless communication terminal even when the subscriber information card is dismounted from the first wireless communication terminal, wherein said uploading is allowed to be executed at least under conditions that the user is confirmed to be an authenticated user of said subscriber information card and an authenticated user of the first wireless communication terminal;
updating contents in a user'"'"'s data storage area with the data being uploaded, in the server;
downloading the data to a second wireless communication terminal via the communication network from the server, the data being confirmed in accordance with a user'"'"'s request or automatically, as data to be downloaded to the second wireless communication terminal from the server, after the subscriber information card having been demounted is mounted on the second wireless communication terminal, said downloading being performed with only data which is present in the storage area of the server and which is not present in the memory of the second wireless communication terminal, wherein said downloading is allowed to be executed at least under conditions that the user is confirmed to be an authenticated user of said subscriber information card and an authenticated user of the second wireless communication terminal; and
updating the contents of the memory in the second wireless communication terminal, said uploading being performed with only data updated after the subscriber information card was mounted on the second wireless communication terminal, while leaving the uploaded data in the memory in the second wireless communication terminal, wherein said uploading is allowed to be executed at least under conditions that the user is confirmed to be an authenticated user of said subscriber information card and an authenticated user of the second wireless communication terminal.

Abstract
In the case where a single user selectively uses plural wireless communication terminals by mounting and demounting a subscriber identification card thereon and therefrom, user convenience in such selective use of the plural terminals can be enhanced by synchronizing user data among those plural terminals. For this purpose, at least updated portion of the data stored in the memory in terminal is uploaded from the first terminal 10a on which SIM card (subscriber information card) 12 is mounted, to a server 50 via a communication network 20, according to a user'"'"'s request or automatically. After the SIM card 12 demounted from the first terminal is mounted on the second terminal 10b or 10c, data to be downloaded to the second terminal from the server 50 is determined according to the user'"'"'s request or automatically, and the data is downloaded to the second terminal from the server 50. In the second terminal, thus downloaded data is used to update the contents in the memory.

6. A wireless communication system comprising plural wireless communication terminals at least communication operation of which is enabled by mounting a subscriber information card recording subscriber information, and a server that is connected with the wireless communication terminals via a communication network, said server comprising:
-
a communication interface which performs data communication with said wireless communication terminals via the communication network; a storage unit which includes a storage area to store a copy of the data stored in said plural wireless communication terminals; and a server side synchronization engine which synchronizes the data of a user stored in the wireless communication terminals and the data stored in the storage unit according to a request from any one of said wireless communication terminals; each of the wireless communication terminals comprising; a card reader which detachably mounts a subscriber information card; a wireless communication interface which is operable when said subscriber information card is mounted; a memory which stores user data; and a terminal side synchronization engine which requests execution of synchronization to said server after said subscriber information card is mounted, uploading or downloading of data being executed with said server as required, said uploading being performed with only data updated after the subscriber information card was mounted on the wireless communication terminal, leaving the uploaded data in the memory even when the subscriber information card is dismounted from the wireless communication terminal, and said downloading being performed with only data which is present in the storage unit of the server and which is not present in the memory of the wireless communication terminal; and at least either one of said server and each of said wireless communication terminals further comprising; an authentication engine which allows only plural wireless communication terminals possessed by an identical user, to perform synchronization as to the user data of the user in the storage unit of said server; said authentication engine being adapted to allow synchronization to be executed at least under conditions that the user who requested the synchronization is confirmed to be an authenticated user of said subscriber information card and an authenticated user of the terminal. - View Dependent Claims (7, 8, 9, 10, 11, 12)
