Abstract:
A mobile radio communication system comprising:a plurality of base stations; anda mobile communications exchanger accommodating said plurality of base stations,wherein said plurality of base stations are coupled to said mobile communications exchanger through signal lines,wherein said plurality of base stations are installed along a road along which a mobile station moves,wherein each base station allocates a same frequency of one of a plurality of radio transmission channels to one of a plurality of mobile stations as a frequency allocated by an adjacent base station which previously dominates said one mobile station, and a same time slot on said one radio transmission channel as a time slot of said one radio transmission channel allocated by said adjacent-base station which previously dominates said one mobile station after a lapse of a fixed time period calculated from a previously assumed moving speed of said one mobile station, when said one mobile station moves at the previously assumed moving speed, andwherein each base station autonomously allocates to one of said mobile stations a different frequency of one of said radio transmission channels from a frequency allocated by an adjacent base station which previously dominates said one mobile station and a different time slot from a time slot on said one radio transmission channel allocated by said adjacent base station which previously dominates said one mobile station, when said one mobile station moves at a moving speed less than a previously assumed moving speed of said one mobile station.
