ABSTRACT:
A wire line data transmission scheme in a mobile communication system for reducing the wire line transmission const. Radio state qualities of a plurality of radio channels between the plurality of base stations and the mobile station are measured, and a validity and a redundancy in composition of each radio channel is judged according to the corresponding measured radio state quality. Then, a transmission in the wire line transmission paths is controlled by stopping a transmission of transmission signals for those radio channels which are judged as invalid or redundant according to the obtained judgement result. All of measuring, judging, and controlling can be carried out by each base station, or by the mobile station. Also, measuring and judging can be carried out by the mobile station while controlling is carried out by each base station, or measuring can be carried out by the mobile station while judging and controlling can be carried out by each base station.
