Abstract
A long term average and a short term value of the strength of a received signal is used to determine a trigger condition in a mobile communications system to perform such functions as control channel or traffic channel reselect. The long term average removes the effects of short term fades in the short term signal that otherwise may cause a premature trigger decision. The short term value offsets historical bias that may be built into long term average. The actual trigger is only realized when both the long term average and the short term value exceed predetermined thresholds in a positive or negative direction.
