摘要

Inter-Frequency Handover (IFHO) is the procedure accounting for the handover of User Equipment (UE) from a serving frequency layer to another. Its proper functioning depends on a plethora of parameters' settings and it is one of the most important aspects affecting the overall UE-perceived performance. The proposed work tackles an optimization procedure for IFHO in Long Term Evolution (LTE)/5G networks. A two-step algorithm based on network Key Performance Indicators (KPIs) processing is designed and presented in detail. Performance assessment is based on the capability of the algorithm to increase network throughput while avoiding degrading behaviors such as ping-pong effects, augmented inter-Radio Access Technology (RAT) handovers, and outage conditions. The algorithm was tested on TIM's network infrastructure over the period August 2020 - January 2021 and it turned out to considerably increase performance with respect to an approach based on standard parameters setting.
