In order to achieve handover to a femtocell without remodeling user equipment, a gateway (50) relays traffic between core networks (60, 70) and a plurality of base stations (20_1 to 20_4) which are respectively incorporated to the core networks (60, 70) through public networks. When the gateway (50) receives a notification from the core networks (60, 70) to handover a mobile station (10) to any one of the plurality of base stations (20_1 to 20_4), the gateway (50) generates an RRC connection release message which prompts the establishment of a new RRC connection. Then, the gateway (50) causes the core networks (60, 70) to instruct a control device (40) which establishes the RRC connection to the mobile station (10), to transfer the RRC connection release message to the mobile station (10). |
