PROBLEM TO BE SOLVED: To efficiently execute a call access processing with regard to a processing method of a call access request signal and with regard to a radio base station control apparatus. SOLUTION: The number of processing of the call access request signal of the radio base station with a low processing completion rate at a vergence is controlled by a step (1-1) for totaling a statistical information of the processing completion rate of each radio base station of the call access request signal (RACH) transmitted and received between a mobile machine and the radio base station, by steps (1-4 to 1-12) for gradually reducing the number of processing of the call access request signal of the radio base station each period at which the processing completion rate is a prescribed threshold value (M%) or lower and for setting a vergence control level so as to gradually increase the number of processing each period at which the processing completion rate is the prescribed threshold value (M%) or higher, and by a step (1-13) for calculating the number of processing of the call access request signal of the radio base station of a vergence control object according to the vergence control level. Also when the number of the call access request signal brought from some of the radio base stations is over a threshold value (N%) of a prescribed ratio of the number of a processable signal, the control of the processing is executed at once.
