PROBLEM TO BE SOLVED: To provide a mobile radio terminal device capable of storing a call arrival history even if an unexpected situation such as battery exhaustion, battery drop or abnormal call end occurs during a call arrival or a talk. SOLUTION: When a call arrival occurs, a control unit 100 stores absence call arrival history data in an absence call arrival history storage area 60a. When an incoming call is answered, said absence call arrival history data are deleted and call arrival history data are stored in a call arrival history data storage area 60b in place of the absence call arrival history data. When a talk ends, the control unit 100 stores talk history data in a talk history storage area 60c. COPYRIGHT: (C)2007,JPO&INPIT
