To provide a portable terminal position estimation method, a portable terminal position estimation device and a portable terminal position estimation system, with which it is possible to reduce a computation load by a simple structure.SOLUTION: A method includes: an acquisition step in which a plurality of communication instruments communicate with a portable terminal and acquires distance information between the communication instruments and the portable terminal and the intensity information of a radio wave; a communication allowability determination step in which it is determined that communication is allowed when the distance information is smaller than or equal to a first prescribed value and the intensity information is greater than or equal to a second prescribed value; an area determination step in which, on the basis of the determination result of the communication allowability determination step and a communication map in which the communicable ranges of respective communication instruments are mapped, a plurality of communication maps are superimposed one on top of another and an area where a portable terminal exists is determined; and an estimation step in which the position of the portable terminal is estimated on the basis of the determination result of the area determination step.SELECTED DRAWING: Figure 3

    【課題】簡便な構成で演算負荷を低減することが可能な携帯端末位置推定方法、携帯端末位置推定装置及び携帯端末位置推定システムを提供する。【解決手段】複数の通信機が携帯端末と通信して通信機及び携帯端末の間の距離情報と電波の強度情報とを取得する取得ステップと、距離情報が第一所定値以下であり、且つ、強度情報が第二所定値以上である場合に通信可であると判定する通信可否判定ステップと、通信可否判定ステップの判定結果と、夫々の通信機の通信可能範囲をマップ化した通信マップとに基づき、複数の通信マップを重ね合わせることにより携帯端末が存在するエリアを判定するエリア判定ステップと、エリア判定ステップの判定結果に基づいて、携帯端末の位置を推定する推定ステップと、を含んでいる。【選択図】図3
