Patent ID: 8583050

Claim:
A building influence estimation apparatus for estimating influence of a building on a mobile communication terminal, comprising: reception information acquiring unit which acquires reception information indicative of a measured reception intensity of a radio wave received by the mobile communication terminal from at least one radio wave transmitter and indicative of the transmitter; location information acquiring unit which acquires location information indicative of a location where the mobile communication terminal received the radio wave; reception intensity estimating unit which performs an estimation and generates an estimated reception intensity of a radio wave from the transmitter indicated by the reception information received by the reception information acquiring unit, according to the location indicated by the location information acquired by the location information acquiring unit; comparing unit which makes a comparison between the estimated reception intensity estimated by the reception intensity estimating unit and the measured reception intensity of the radio wave indicated by the reception information acquired by the reception information acquiring unit; building influence estimating unit which estimates an influence of the building on the mobile communication terminal, based on a result of the comparison by the comparing unit; and outputting unit which outputs information indicative of the influence of the building estimated by the building influence estimating unit, wherein the reception intensity estimating unit generates estimated reception intensities of radio waves from the transmitter for a plurality of locations in a predetermined range based on the location indicated by the location information, and generates the estimated reception intensity of the radio wave according to the location indicated by the location information, from the estimated reception intensities for the plurality of locations, wherein the reception intensity estimating unit calculates statistical values for respective transmitters from measured reception intensities of radio waves from the transmitters at the plurality of locations and defines the statistical values as estimated reception intensities of the radio waves according to the location indicated by the location information, and wherein the comparing unit makes a comparison between each of the estimated reception intensities of the respective transmitters estimated by the reception intensity estimating unit and the measured reception intensity of the radio wave indicated by the information received by the reception information acquiring unit.
