CONDITIONING REMOVAL OF AN OVERLAY CARRIER FREQUENCY FROM A CELLULAR WIRELESS COVERAGE AREA

摘要

Disclosed herein is a method to condition removal of a carrier frequency from a wireless coverage area. The method involves evaluating handoff statistics for the coverage area, and applying results of past carrier frequency removal (preferably from a morphologically similar cluster) to predict a net change in hard handoffs that will result if the carrier frequency is removed. The method then involves using the predicted net change in hard handoffs as a basis to determine whether to remove the carrier frequency. For instance, the predicted net change in hard handoffs may be converted to a corresponding predicted net change in call drops, and the carrier frequency may be removed only if the predicted net change in call drops does not exceed a threshold.
