Abstract
A method and system for performing handoffs in radiocommunication systems using a time variable hysteresis value are described. By varying the hysteresis value in accordance with the amount of time that the mobile station has been using a current channel, problems associated with the measurement of signal strengths attributable to filter initialization can be avoided.
