Handover parameter optimization in self-organizing network

This paper presents a self-optimizing algorithm that adjusts the handover parameters between IMT-Advanced base stations in order to improve the overall network performance and diminish negative effects (call drops, handover failures). The proposed algorithm picks the best hysteresis and time-to-trigger combination for the current network status. The effects of this self-optimizing algorithm are examined through simulation and the results show an improvement from the static value settings.
