PROBLEM TO BE SOLVED: To share data among information terminals without centralizedly managing position information of all the information terminals, when information terminals located close to each other are linked and perform information processing.SOLUTION: Each base device 1 for controlling data transfer operation with an information terminal 11 causes a terminal connection determination unit 28 to determine whether or not a connection state to the information terminal 11 measured by a terminal connection state measurement unit 29 satisfies connection permission conditions registered in a determination condition storage unit 27. The base device connects the information terminal 11 that satisfies the connection permission conditions, and stores terminal information thereof in a connection terminal information storage unit 24. A terminal notification unit 25 notifies the connected information terminal 11 of an inquiry relating to a copy of common data. As a result, when a terminal-base data transfer unit 22 receives the common data from the information terminal 11, the base device stores the common data in the data storage unit 21, such that other information terminals 11 located nearby and connected to the same base device 1 can refer thereto. |
