A call admission priority control determination device is intended for determining, when a terminal is present in a femtocell and the terminal is to be admitted for call connection, whether it is to be connected to the femtocell or to a macro-cell. The number of remaining connections and a remaining rate in the femtocell if a new call is admitted are figured out. For a specified terminal so registered as to be given priority in connection to the femtocell, the call is admitted if the number of remaining connections and the remaining rate are equal to or greater than 0, but for other terminals than the specified ones in the pertinent femtocell, the call is not admitted if the number of remaining connections and the remaining rate are below certain thresholds.
