Patent ID: 7149486

Claim:
A mobile communication system comprising: a plurality of base stations; and a plurality of mobile communication terminals each of which transmits a communication request to one of the plurality of base stations and communicates with the base station, each of the plurality of base stations comprising: means for calculating an evaluation function value of each of a plurality of mobile communication terminals which have transmitted the communication requests, on the basis of at least communication quality between the base station and mobile communication terminal; means for selecting a mobile communication terminal as a communication destination on the basis of the calculated evaluation function value of each mobile communication terminal, and communicating with the selected mobile communication terminal; means for calculating an evaluation function threshold value representing a selection standard, on the basis of an evaluation function value of a mobile communication terminal selected in a past predetermined period; and means for transmitting the calculated evaluation function threshold value to the plurality of mobile communication terminals, and each of the plurality of mobile communication terminals comprising: means for receiving an evaluation function threshold value of each base station transmitted from the base station; means for calculating an evaluation function value of each of the plurality of base stations on the basis of communication quality between the mobile communication terminal and base station; means for comparing the calculated evaluation function value of each base station with the received evaluation function threshold value, and, on the basis of the comparison result, selecting a base station which is highly likely to select the own mobile communication terminal; and means for transmitting the communication request to the selected base station.
