Abstract:
A mobile communication apparatus which selects any one of a plurality of base stations to communicate therewith, comprising:extracting means for extracting surrounding base stations of a mobile unit within a certain defined area centered at a present location of said mobile unit; and base station selecting means for carrying out an arithmetic operation for obtaining a specified weighting coefficient with respect to each of said extracted surrounding base stations on the basis of a direction of each of said extracted surrounding base stations from said present location of said mobile unit and a traveling direction of said mobile unit, for carrying out further arithmetic operation for weighting a value of said electric field strength of a signal received from each of said surrounding base stations with said weighting coefficient of a corresponding surrounding base station to provide a weighted electric field strength of each of said extracted surrounding base station, and for selecting said one base station from said extracted surrounding base stations depending on a value of said weighted electric field strength.
