PROBLEM TO BE SOLVED: To estimate, in a mobile terminal, the location of the mobile terminal itself by a fingerprint positioning technique while requiring a small storage capacity and arithmetic operation amount. ! SOLUTION: Provided is a mobile terminal for determining its own location by comparing an observation value at the mobile terminal of a wireless signal from a plurality of communication devices whose locations are fixed and a reference value that is the observation value or the prediction value of a wireless signal from each of the plurality of communication devices at each of a plurality of reference locations stored in a network including the plurality of communication devices, where the mobile terminal acquires a reference value corresponding to a geographical area including the location at which the mobile terminal is present from any of the plurality of communication devices, compares the acquired reference value corresponding to the geographical area and the observation value at the mobile |
