Abstract:
A system for detecting a position of a radio mobile station in a wireless radiocommunication system for radiocommunications between said mobile station and a plurality of base stations, said detection system comprising:a radio strength data storage section for retaining radio strength data including positional information of a plurality of measuring points expressible with a continuous value and reception radio strength levels from said plurality of base stations at said plurality of measuring points; a position detection section for comparing said radio strength data in said radio strength data storage section with radio strength levels at a position detecting point; and an error radio strength data storage section for retaining a plurality of radio strength data involving small errors of errors serving as comparison references in said position detection section, and further for retaining the corresponding position information at that time, wherein said position detection section estimates and detects a position of said mobile station on the basis of said plurality of radio strength data stored in said error radio strength data storage section so that the detected position is not limited to said measuring points but is within a range smaller than an interval of said measuring points.
