SOLUTION: In a mobile communication system, a base station 18 to transmit and receive radio between itself and a radiocommunication system 14 is installed. This radiocommunication terminal 14 is equipped with a transmitter- receiver for mobile communication for transmission and reception between itself and the base station 18, and a bluetooth unit 15 for short-distance radio data communication by relatively week waves in addition to this. When the radiocommunication terminal 14 is at a distance where it can communicate with a fixed station 16 for the bluetooth, it can acquire the positional data of this radiocommunication terminal 14 and the shop information, etc., relevant to this positional data from this fixed station 16.</p> |
