Wireless channel changeover method and mobile communication system

摘要

A mobile communication system includes a plurality of base stations (111) and a mobile station (112) communicating with the base station (111) through a wireless channel. The system comprises a part (16; 16') which measures an amount of information transferred between the base station (111) and the mobile station (112) and a comparator (16; 16') which compares the measured amount of information with first and second threshold values corresponding to a currently used wireless channel. A wireless channel changeover part (17; 17') changes the current wireless channel to a wireless channel with a transmission capability higher or lower than that of the current wireless channel when the measured amount of information is above the first threshold value or below the second threshold value, respectively.
