摘要
In this paper we analyze the performance of a self optimizing algorithm for handover parameter control which adjusts the settings depending on the oscillations experienced between different cell pairs. We compare the algorithm performance with two different reference cases. The first one allowing the system to trigger handover as soon as the best perceived cell changes, with the users connected always to the best server. The second one protecting the system against oscillations by setting default values for time to trigger (TTT) and handover margin (HOM). We observe that introducing the handover parameters reduces the oscillations but has a strong negative effect on the performance. With the self-optimizing algorithm the system performance is better while the oscillations are mitigated at similar levels.
