Abstract
A femto GW provides a network connection to an MS that is radio-accommodated in a femto BS. Upon reception of a position registration confirmation for the MS, if the MS has been radio-accommodated in a BS or the femto BS within a specific calling area including a calling area for the femto BS immediately before reception of the position registration confirmation, and the MS that has been radio-accommodated in the specific calling area is withdrawing itself from the calling area, a transmission stop command for stopping radio transmission to the MS is sent to the femto BS.

A gateway device, comprising:
- a network connection providing unit that provides network connection to a mobile subscriber radio-accommodated in a specific base station among base stations each radio-accommodating mobile subscribers in a corresponding calling area;
- a receiving unit that receives a message related to movement or position registration of the mobile subscriber;
- a first subscriber existence determining unit that determines whether the mobile subscriber radio-accommodated in the base station in a specific calling area including a calling area of the specific base station withdraws, when the message is received in the receiving unit;
- and
- a command control unit that transmits a transmission stop command that instructs to stop radio transmission to the mobile subscriber, to the specific base station, when it is determined by the first subscriber existence determining unit that the mobile subscriber radio-accommodated in the base station in the specific calling area withdraws.
