Abstract

In a handover control apparatus, a terminal is wirelessly connected with one of base stations to establish a wireless data communications connection. The terminal executes a handover process using a handover process section when an electric wave state becomes lower than a threshold value, which is variable. The threshold value can be adjusted according to a moving speed of the terminal. Furthermore, the threshold value is corrected according to the past electric wave state. The threshold value is corrected according to a difference of (i) a minimum electric wave state in a preceding handover process, and (ii) a lower limit. The correction is executed so as to reduce an excessive decline of an electric wave state in a succeeding handover process. Deterioration of a communications quality during a handover process can be thereby suppressed.
