An access gateway device is disclosed that is used in a mobile communication system and that is capable of storing an identifier of a tracking area in which a mobile station in communication is located. The access gateway device includes a table unit storing a table having a corresponding relationships between a tracking area and a base station managing a cell included in the tracking area; a tracking area identifier comparison unit referring to the table at a predetermined timing, detecting the identifier of the tracking area in which the mobile station is located, and comparing the detected identifier of the tracking area with the stored identifier; and a tracking area identifier notification unit notifying the mobile station of the detected identifier of the tracking area when the detected identifier of the tracking area is different from the stored identifier based on a result of the comparison.

A relay node RN according to the present invention includes an MBSFN subframe setting information acquisition unit 11 configured to acquire setting information from a radio base station DeNB in an RRC connection setting process with the radio base station DeNB, a reception unit 14 configured to receive an uplink signal from the mobile station UE in a first period, and to receive a downlink signal from the radio base station DeNB in an MBSFN subframe based on the acquired setting information, and a transmission unit 13 configured to transmit a downlink signal to the mobile station UE in a second period, wherein the transmission unit 13 and the reception unit 14 are configured such that the first period and the second period are alternately switched to be a half of RTT of synchronous HARQ control.
摘要:
Provided is a radio base station eNB including a transmission timing decision unit and a system information transmission unit. The transmission timing decision unit decides a transmission radio frame according to an offset Xk from a transmission timing of a first system information SI-1 and a transmission cycle Tk for other system information k and decides a transmission sub-frame in a decided transmission radio frame according to scheduling information contained in the first system information SI-1. The system information transmission unit transmits other system information k in the decided transmission sub-frame. The offset Xk is defined so as to be different for each transmission cycle Tk.
