Adaptive handoff method using location information

This paper presents an inter-cell (hard) handoff algorithm that calculates adaptive handoff hysteresis values based on mobile location information and cell RF propagation statistics. The analysis is focused on the probability of handoff and the probability of dropped calls in the system. Simulation results show that the probability of unnecessary handoff is reduced using the adaptive handoff algorithm with only a minor increase in the dropped-call probability. This improvement is significant if the propagation signal varies rapidly in the cell.
