摘要： A wireless communication system is provided in which a relay station relays wireless communication between a base station and a mobile station. The relay station includes an acquiring unit and a notifying unit. The acquiring unit acquires, from the base station that retains information on the mobile station used for the wireless communication, identification information on the base station. The notifying unit notifies the mobile station of the identification information acquired by the acquiring unit. Furthermore, the mobile station includes a reconnecting unit. When connection with the relay station is released, the reconnecting unit performs a reconnection request with respect to the base station that is identified by the identification information that is notified by the relay station.

摘要： When completing radio communication with a radio terminal, a transmitting unit of a base station transmits to the radio terminal a validity period of control information on radio communication which has been used to communicate with the radio terminal. When starting radio communication with the radio terminal within the validity period, a communication unit of the base station performs radio communication with the radio terminal without performing a process of exchanging control information. When completing radio communication with the base station, a receiving unit of the radio terminal receives a validity period from the base station. When starting radio communication with the base station within the validity period, a communication unit of the radio terminal performs radio communication with the radio terminal without performing a process of exchanging control information.
