Abstract
A mobile communication system includes a mobile station connected with a base station by radio when being in a cell formed by the base station, and configured to communicate with a counter side unit through the base station; and a relay station configured to form a limitation area. The relay station receives a downlink signal from the base station and transmits a limitation downlink signal obtained by adding information showing that it is in the limitation area to the downlink signal to the limitation area. When receiving the limitation downlink signal, the mobile station transmits an uplink signal showing a function limited state to the base station in synchronization with a downlink channel received from the base station.
