The proposed thesis work tackles an optimization procedure for inter-frequency handover in LTE networks. In order to do that, a two steps algorithm based on local KPIs observation was designed and is therefore presented in detail. The algorithm consists of a two step procedure, comprising a numerical processing of the observed KPIs and a monitoring phase in order to balance and limit possible negative effects such as ping-pong handovers, outage conditions or reduced end-user throughput. The algorithm was validated with a tests campaign performed on a real network infrastructure over the months of August and September. The final objective of this optimization procedure, in the end, can be measured in terms of increased end-user throughput. For this purpose, all conducted tests are thoroughly analyzed and the obtained results are commented. In the final sections and appendixes some foreseen evolutions and enhancements of the model are discussed.
