MOBILE COMMUNICATION TERMINAL, AND CONTROL METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a mobile communication terminal which can effectively execute multi-mode communication corresponding to a battery voltage without causing an unanticipated situation for a user, and to provide a control method thereof. SOLUTION: The mobile communication terminal includes: first radio communication means 102 corresponding to a first radio communication system; an interface 107 which can detachably connect an external device 200; decision means 111 which judges whether or not the external device 200 connected to the interface 107 is second radio communication means 202 which corresponds to a second radio communication system and consumes less power than the first radio communication means 102; battery voltage detection means 104 which detects the battery voltage of a power source unit 103 including a battery; and control means 111 which sets the first radio communication means 102 to a use-stop state if the first radio communication means 102 is being communicating and the battery voltage detected by the battery voltage detection means 104 is not greater than a prescribed value when the decision means 111 judges a connection of the second radio communication means 202.
