Abstract:
1. A method for changing wireless channels used in a communication between a base station and a mobile station, comprising the steps of: a) measuring an amount of information transferred between the base station and the mobile station; b) comparing the measured amount of information with first and second threshold values corresponding to a transmission capability for a current wireless channel being used between the base station and the mobile station; and c) changing the current wireless channel to the wireless channel with a higher transmission capability than that of the current wireless channel when the measured amount of information is above the first threshold value and changing the current wireless channel to the wireless channel with a lower transmission capability than that of the current wireless channel when the measured amount of information is below the second threshold value, wherein an amount of information yet to be transmitted is measured as said amount of information to be compared with the first threshold value, and wherein an amount of information currently being transmitted is measured as said amount of information to be compared with the second threshold value.
