Handover criterion for macro and microcellular systems

In order to realize fast handover in both microcells and macrocells, the relationship between averaging, the received signal level comparison method, and handover detection delay was analyzed. The analytical results were verified by handover simulations performed using experimental propagation data. As the criterion for accurate and stable handover in both the macrocell and the microcell, a combined handover decision is suggested which consists of long-term averaging with a small hysteresis margin and short-term averaging with a large hysteresis margin.<<ETX>>
