Radio base station device setting system and method for re-setting communication configurations for radio base station device

Abstract

When an information storage unit of a radio base station setting device includes information related to a CDMA radio base station device which has supplied discrimination information, the radio base station setting device deletes the information from the information storage unit, and estimates the location of the CDMA radio base station device. The radio base station setting device reads communication configurations for existing radio base station devices installed around the estimated location from the information storage unit. The radio base station setting device determines communication configurations for the CDMA radio base station device based on the read communication configurations for the existing radio base station devices, and the estimated location.
