A communication duration configuring method is used in a mobile communication system including a mobile relay station for relaying a wireless communication between a base station and a mobile station. The method includes: configuring at least any of a downlink communication duration where the relay station receives a transmission signal from the base station by restricting a transmission of a signal from the relay station to the mobile station and an uplink communication duration where the relay station transmits a transmission signal to the base station by restricting a transmission of a signal from the mobile station to the relay station; and restricting a transmission of a signal with the mobile station in a first period from detection of a handover until when the communication duration is configured between the relay station and a target base station, and using a desired duration within the first period.
