In a cellular mobile communication system that operates in a first state in which a mobile station has not established a connection with a base station and in a second state in which the connection has been established with any of the base stations, a cell in which criteria for the cell reselection by the mobile station and criteria for handover are not aligned is specified. The mobile station transmits cell selection history to the base station of a second cell when handing over from a first cell to the second cell in accordance with second criteria for handover in the second state, the cell selection history containing a history of cell selection performed in accordance with first criteria for cell reselection in the first state. The base station of the second cell refers to the transmitted cell selection history, and when it is determined that the mobile station has been handed over from the first cell to the second cell within a predetermined period after transition from the first state to the second state, specifies the cell in which the first criteria and the second criteria are not aligned from among the first cell and the second cell on the basis of the cell selection history. |
