Abstract:
A method of cell selection in a CDMA mobile communication system in which a plurality of base stations are provided in respective cells and mutually different spread codes are assigned to said plurality of base stations, the method comprising the steps of:transmitting from each base station a perch channel which is spread by using a spread. code assigned to each base station;receiving more than one perch channels transmitted from more than one base stations at a mobile station, calculating a transmission attenuation value of each received perch channel, and judging a located cell according to calculated transmission attenuation values of said more than one perch channels; andnotifying from each base station to the mobile station a perch channel transmission power information for each perch channel transmitted from each base station;wherein the mobile station calculates the transmission attenuation value of each received perch channel from a notified perch channel transmission power information for each received perch channel and a perch channel receiving level of each received perch channel.
