When the frame rate changes from eighth rate to full rate, the power control process increases the .sup.E.sub.b /.sub.N.sub..sub.o target by .DELTA..sub.1. If the frame rate changes from full rate to eighth rate, the power control process decreases the .sup.E.sub.b /.sub.N.sub..sub.o target by .DELT

When the frame rate changes from eighth rate to full rate, the power control process increases the .sup.E.sub.b /.sub.N.sub..sub.o target by .DELTA..sub.1. If the frame rate changes from full rate to eighth rate, the power control process decreases the .sup.E.sub.b /.sub.N.sub..sub.o target by .DELTA..sub.2. In both cases, a decision threshold for a Frame Quality Metric is determined. If the Frame Quality Metric is less than the threshold, normal power control is resumed. If the Frame Quality Metric is greater than or equal to the threshold, the newly set target .sup.E.sub.b /.sub.N.sub..sub.o is decreased by A.sub.3. The target .sup.E.sub.b /.sub.N.sub..sub.o is continually decreased by A until the frame rate changes or the target reaches the required .sup.E.sub.b /.sub.N.sub..sub.o , indicated by a bad frame or lower frame quality metric (i.e., lower than the frame quality threshold).

[ We claim:] [1.] A method for updating a target system performance metric in a digital radiotelephone system comprising base stations and a radiotelephone, frames of data are communicated between the radiotelephone and the base stations, each frame communicated at one of a plurality of frame rates, the method comprising the steps of:determining if the frame rate has changed;if the frame rate changed from a lower frame rate to a higher frame rate, increasing the target system performance metric by a first predetermined delta to create an updated target metric;if the frame rate changed from the higher frame rate to the lower frame rate, decreasing the target system performance metric by a second predetermined delta to create the updated target metric;determining a frame quality threshold;determining a frame quality metric for the communicated frames; andif the frame quality metric is greater than the frame quality threshold, subtracting a third predetermined delta from the updated target metric.
