Abstract: A position information acquisition system has a terminal and a position information acquisition server for acquiring position information for the terminal. The terminal has a radio wave intensity measurement unit for receiving first radio wave intensities of radio waves received by a plurality of access points and associating the received first radio wave intensities with access point identifiers, and a moving/stationary determination unit for determining whether the terminal is moving or stationary. The position information acquisition server has a position information table in which second radio wave intensities of radio waves received from the plurality of access points are associated with position information, and a radio-wave-intensity/position conversion unit for retrieving second radio wave intensities corresponding to the received first radio wave intensities, and acquiring position information corresponding to the retrieved second radio wave intensities.
