Abstract

An information processing apparatus connected to a wireless base station configured to wirelessly communicate with a plurality of terminals, the wireless base station providing a predetermined point on a map to each of the plurality of the terminals as a reference position serving as a positioning reference. The information processing apparatus includes a information acquisition processor, a position calculator, a memory, a proximity detector, and a position updater. The proximity detector determines existence of a proximity terminal within a range of a preset proximity distance based on the radio field intensity on the inter-terminal communication for each of the plurality of the terminals obtained from each of the plurality of the terminals. The position updater updates the measured positions of the relevant terminal within the range of the proximity distance stored in the memory by using the estimated position of the proximity terminal determined as existing within the range of the proximity distance by the proximity detector.
