A method and system for determining handoff priority based on relative change of measured signal intensity

摘要

A handoff control system which can decrease the probability of forced termination of communication by considering the time allowed for handoff processing for each mobile terminal is provided. A handoff control system for performing a handoff processing for a mobile terminal, that moves across cells of a plurality of base stations while performing mobile communication, comprises the mobile terminal which periodically measures a reception signal intensity of a radio signal used for a current communication, calculates a relative change value of reception signal intensity at measurement time intervals, and periodically reports the measured reception signal intensity and the calculated relative change value of reception signal intensity; and the base station which periodically receives and stores the reception signal intensity and the relative change value of reception signal intensity respectively reported from the mobile terminal, and performs a handoff processing by giving a higher priority to a handoff request of a mobile terminal for which the stored relative change value of reception signal intensity is larger and the stored reception signal intensity is weaker.
