Abstract

A mobile communication apparatus and method which extract surrounding base stations within a certain defined area centered at a present location of a mobile unit, carry out an arithmetic operation for obtaining a specified weighting coefficient with respect to each of the extracted surrounding base stations on the basis of a direction of each of the extracted surrounding base stations from the present location of the mobile unit and a traveling direction of the mobile unit carry out a further arithmetic operation for weighting a value of the electric field strength of a signal recieved from each of the surrounding base stations with the weighting coefficient of a corresponding surrounding base station to provide a weighted electric field strength of each of the extracted surrounding base station, and select the one base station from the extracted surrounding base stations depending on a value of the weighted electric field strength.
