A radio unit and other units communicate with a base station apparatus. The radio unit and other units are capable of performing multiple types of communications. An acquisition unit acquires communication quality and moving speed. A determination unit determines the execution of a handover based on acquired quality and moving speed. The determination unit specifies, from among acquired quality and moving speed, a parameter used to determine the execution of a handover, based on the type of performed communication. An instruction unit instructs the radio unit and other units to perform a handover.
