A femto gateway, comprising: an adjacent-base-station information storage means configured to hold adjacent-base-station information, the adjacent-base-station information being information on a base station (10, 20) adjacent to a femto cell base station; a control unit configured to cause the femto gateway to: communicate with a core node, communicate with a femto cell base station, detect a failure of communication with the core node, transmit a service suspension notification to the femto cell base station when the communication failure has been detected, and transmit the adjacent-base-station information to the femto cell base station when the failure of communication with the core node is detected, wherein the adjacent-base-station information includes information about macro cell base stations (10a, 10b, 10c), wherein the adjacent-base-station information comprises a plurality of pieces of adjacent-base-station information, and wherein to the plurality of adj acent-base-station information an order of priority based on easiness of connection from a terminal located within a communication range of the femto cell base station is set, and wherein the service suspension notification transmitted to the femto cell base station causes the femto cell base station to transmit the adjacent-base-station information to a terminal connected with the femto cell base station and to release the connection with the terminal. an adjacent-base-station information storage means configured to hold adjacent-base-station information, the adjacent-base-station information being information on a base station (10, 20) adjacent to a femto cell base station; a control unit configured to cause the femto gateway to: communicate with a core node, communicate with a femto cell base station, detect a failure of communication with the core node, transmit a service suspension notification to the femto cell base station when the communication failure has been detected, and transmit the adjacent-base-station information to the femto cell base station when the failure of communication with the core node is detected, communicate with a core node, communicate with a femto cell base station, detect a failure of communication with the core node, transmit a service suspension notification to the femto cell base station when the communication failure has been detected, and transmit the adjacent-base-station information to the femto cell base station when the failure of communication with the core node is detected, wherein the adjacent-base-station information includes information about macro cell base stations (10a, 10b, 10c), wherein the adjacent-base-station information comprises a plurality of pieces of adjacent-base-station information, and wherein to the plurality of adj acent-base-station information an order of priority based on easiness of connection from a terminal located within a communication range of the femto cell base station is set, and wherein the service suspension notification transmitted to the femto cell base station causes the femto cell base station to transmit the adjacent-base-station information to a terminal connected with the femto cell base station and to release the connection with the terminal.
