A handover control method comprises: a step in which a mobile station measures radio qualities in a plurality of different frequency cells at predetermined measurement intervals; and a step in which the mobile station, when determining that the radio quality in a specific frequency cell satisfies a report condition, starts up a timer for measuring the time during which the radio quality in the specific frequency cell continues to satisfy the report condition and, when the timer has expired, transmits to a radio base station a measurement report including the radio quality in the specific frequency cell. The mobile station, after determining that the radio quality in a second frequency cell satisfies the report condition and starting up a second timer, stops the second timer and starts up a first timer when determining that the radio quality in a first frequency cell having a higher priority than that of the second frequency cell satisfies the report condition.
