<P>PROBLEM TO BE SOLVED: To provide a method for adjusting an overload control threshold. <P>SOLUTION: The method includes a step for adjusting the overload control threshold at least on the basis of one failure event metric and the overload control history. The overload control is executed on the basis of the overload control threshold. In the method, when the overload control history shows that rate reduction is not executed, the overload control threshold is left unchanged in the adjustment process. When the overload control history shows that at least one rate reduction is executed and the failure metric shows the failure event, the overload control threshold is reduced in the adjustment process, and also, when the overload control history shows that at least one rate reduction is executed and the failure metric does not show the failure event, the overload control threshold is increased in the adjustment process. A noise floor is established on the basis of the determination whether an access terminal in a serving region supports a silence interval or not. <P>COPYRIGHT: (C)2006,JPO&NCIPI
