Mobile body position detection method

Abstract

Abstract PURPOSE:To detect the position of a mobile body with high accuracy more than in the unit of radio zone without requiring large installation investment by collating a reception electric field level in a mobile station of a base station transmission wave with the level in an electric field strength map so as to detect the position of the mobile station in existence in an area. CONSTITUTION:A mobile station 10 identifies and detects the reception electric field level of a base station transmission wave of a mobile body communication system for each of base stations 21-23, and the mobile station or a communication party to the mobile station 10 collates the level of an electric field strength map 90 whose position is made correspondent with the reception electric field level with the received electric field level to be detected for each of the base stations 21-23. Thus, the position of the mobile station 10 is detected more accurately than that in the radio unit zone of the mobile body communication system and the equipment required for the detention is simplified.
