MOBILE DEVICE, COMMUNICATION SYSTEM AND METHOD FOR CONTROLLING COMMUNICATION

PROBLEM TO BE SOLVED: To simply perform connecting operation in near-distance radio communication. SOLUTION: A terminal A transmits a bluetooth connection request to opposite terminals B, C by an e-mail through a mobile communication network (S101). Then the terminal A makes it possible to execute bluetooth communication and shifts its mode to a connection scanning mode to wait for connection requests from the terminals B, C (S102). In the case of requesting connection with the terminal A, each of the terminals B, C makes it possible to execute bluetooth communication and transmits a bluetooth connection request to the terminal A which is a requesting source (S103). Thereby the bluetooth connection request is transmitted from each of the terminals B, C to the terminal A (S104) and authentication based on bluetooth standards is executed (S105A). When the authentication result is normal, bluetooth connection between the terminals A, B or between the terminals A, C is completed (S106). Since the connection request is transmitted/received by the e-mail, a process for connecting a connectable mobile machine after retrieval can be omitted and connecting operation can be simplified.
