Abstract

A method for compensating for capacity overload in a communication system by first determining the received signal power level at a base site (62) is described. The power level is compared with a threshold power level (63). If the received power level is greater than the threshold, the signal-to-noise ratio for the system is reduced (65). With the acceptable signal-to-noise ratio reduced, the subscriber power will be reduced. The received signal power level at the base site will then return to the threshold level.
Alternatively, a signal-to-noise ratio of a pilot signal can be determined (62) at the base. The signal-to-noise ratio is compared to a threshold signal-to-noise ratio (63). If the signal-to-noise ratio of the pilot is less than the threshold, the threshold level is reduced (65). With the acceptable signal-to-noise ratio reduced, the subscribers are directed to reduce their power.
