A mobile station (100) includes: a cell selector unit (106) configured to perform a cell reselection procedure for a predetermined period after a failure of a detection of a radio link with a first radio base station which manages a first cell; a connection re-establishment request signal transmitter unit (102) configured to transmit a connection re-establishment request signal to a second radio base station managing a selected second cell, when it is determined that the second cell is a cell using the same radio access scheme as that of the first cell; and a connection recovery procedure starter unit (116) configured to start a connection recovery procedure for a mobile exchange station managing the second radio base station, when it is determined that a response signal received from a second radio base station in response to the connection re-establishment request signal is a signal indicating rejection of connection re-establishment, or when it is determined that the second cell is a cell using a different radio access scheme from that of the first cell.
