摘要： A wireless base station apparatus includes a reporting unit which reports information on a first transmission area that allows transmission of a random access signal. Accordingly, the first transmission area is wholly reported to mobile station apparatuses within an area of the wireless base station apparatus. That is, both a mobile station apparatus in a non-handover state and a mobile station apparatus in a handover state receive the first transmission area information (report information) and use the first transmission area as a transmission area for transmitting a random access signal to the wireless base station apparatus. The wireless base station apparatus also has a notifying unit which notifies a second transmission area to a mobile station apparatus in a handover state, the second transmission area being different from the first transmission area reported by the reporting unit of the handover-destination wireless base station apparatus.

摘要： A radio communication system includes a relay station, a first radio base station, second radio base stations, and a mobile station. The relay station is connected by radio to the first radio base station and communicates with the second radio base stations via the first radio base station. When the relay station communicates with the second radio base stations, the relay station requests the first radio base station to communicate with the second radio base stations for the relay station. The requested first radio base station communicates with the second radio base stations for the relay station and transmits a communication result to the relay station.

摘要： In an intermittent communication system where an intermittent communication can be made between a base station and a mobile station, a transmitting unit of the mobile station transmits a request to start a normal communication after stopping an intermittent communication at timing different from the intermittent communication if a handover is determined to be required. A transiting unit transits from the intermittent communication to the normal communication after the transmitting unit transmits the request. A handover performing unit performs a handover upon completion of transition to the normal communication by the transiting unit.
