Abstract

A communication system having a first base station commmunicating with a mobile terminal by a first signal having a first pathloss. A second base station communicates with the mobile terminal by a second signal having a second pathloss. A memory stores a first hysteresis associated with a first range of pathloss and a second hysteresis associated with a second range of pathloss. A processor selects a handoff hysteresis between the first hysteresis and the second hysteresis based on one of the first pathloss and the second pathloss. A controller switches primary communication of the mobile terminal from one of the first and second signals to the other of the first and second signals when the pathloss determined for one of the first and second signals is greater than the pathloss for the other of the first and second signals by an amount at least equal to the selected handoff hysteresis.
