Abstract
A method and system for handing off an on-going communication from a serving cell to a neighboring cell of a cellular communication system having mobile units with a scanning capability. A dynamic threshold is calculated for effecting the handoff under certain operating criteria. The minimum attenuation level of the mobile unit and the minimum level permitted by a neighboring cell is used in selecting the dynamic threshold.
