TERMINAL APPARATUS, POSITION ESTIMATING METHOD, POSITION ESTIMATING SYSTEM, AND COMPUTER-READABLE STORAGE MEDIUM

A mobile terminal communicable with a plurality of base stations narrows down candidate positions of the mobile terminal estimated from signals received from the plurality of base stations, based on missing data of the signals received from a certain base station, and estimates a position of the mobile terminal from the narrowed down candidate positions, based on an observation probability of intensities of the signals received.
