A femto GW (12) provides a network connection to an MS (2) that is radio-accommodated in a femto BS (7). Upon reception of a position registration confirmation for the MS (2), if the MS (2) has been radio-accommodated in a BS (3) or the femto BS (7) within a specific calling area including a calling area for the femto BS (7) immediately before reception of the position registration confirmation, and the MS (2) 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 (2) is sent to the femto BS (7). |
