Abstract
A method of protecting voice calls in danger of being dropped from a cell of a wireless communication system due to high speed data users. The method including the steps of calculating a signal-to-noise ratio based upon a forward link of each of the plurality of traffic channels within the cell and detecting when the cell is in a overload condition. The method further determines the gain associated with each traffic channels within the cell as well as the channels associated priority level. The method then reduces the gain on the traffic channels with the lowest priority to save the voice call from being disconnected.
