A radio terminal (100) according to a present invention stores a handover threshold in association with an application being executed, when the communication quality of the application is degraded, the handover threshold being based on a piece of radio state information equivalent to that at a time when the communication quality is determined to be degraded. The radio terminal (100) stores the amount of variation of the radio state information in association with the radio communication system. The radio terminal (100) executes handover to a different radio communication system on the basis of the radio state information, the stored handover threshold and the stored amount of the variation.
