  • Information processing device
    Patent number: 11432111
    Abstract: A server performs: acquiring measurement data of a mobile terminal; extracting fixed AP measurement data of a specific fixed AP; extracting measurement data including a measurement time of which a difference from the measurement time in the fixed AP measurement data is equal to or less than a threshold value, position information of which a difference from a position of the specific fixed AP is equal to or less than a threshold value, and a reception intensity of which a difference from the reception intensity in the fixed AP measurement data is equal to or less than a threshold value as target measurement data and to set the radio access point corresponding to the target measurement data as a target AP; and determining whether the target AP corresponds to a fixed AP on the basis of the measurement data corresponding to the target AP and the fixed AP measurement data.
