PROBLEM TO BE SOLVED: To obtain a data communication system where the communication cost is reduced and the storage capacity of a storage device of a mobile station is suppressed by interposing a base station to communication between a mobile body and an installation so as to make the communications via the base station. SOLUTION: A base station 20 that intermediates between a mobile station 10 and an information station 30 in data communication is placed in a user's hone or the like corresponding to the mobile station 10. The mobile station 10 sends a command of requesting communications with the information station 30 to the base station 20 and the base station 20 makes data communication based on the command. Then the base station 20 edits the information acquired from the information station 30 and returns required information to the mobile station 20. The mobile station 10 stores the returned information to a storage means 12 and outputs displays the information to an output means 14. |
