Abstract
Each base station measures the field intensity of downlink rediowaves from other base stations, then analyzes the received rediowaves above a predetermined field intensity value and decides whether they are rediowaves used in the same mobile radio communication system. The base station creates peripheral base station information based on information about the rediowaves decided as being used in the same mobile radio communication system.
