A gateway information storage device (60) includes a gateway information storage unit (61) which stores gateway information indicating a gateway (GW) to which a mobile terminal (10) is being connected. An access device (20) includes: a gateway information acquiring unit (23) which acquires the gateway information from the gateway information storage device (60) in response to a connection request in handover that is received from the mobile terminal (10); and a connection processor unit (22) which establishes a connection between the mobile terminal (10) and a gateway (GW20B) identified by the gateway information acquired from the gateway information storage device (60).
