Abstract:
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.
