Handover delay and hysteresis margin in microcells and macrocells

Abstract

Handover performance is examined in terms of reductions in unnecessary handovers and delay time. An analytical method is described to determine the optimum hysteresis level and signal averaging time for both micro- and macro-cells. Results demonstrate the possible compromise between handover parameters, i.e. signal averaging time and hysteresis level, under the influence of shadow fading. These results could be used in setting the parameters of the handover algorithm to achieve less delay in handover decision making and less unnecessary handovers.
