Abstract

This paper introduces an enhanced automatic self-optimization technique that picks up the best handover (HO) limits of long-term evolution (LTE) transceivers. The goal is to minimize the possible degradation due to HO call drop, HO failure (HOF) and Ping-Pong HO to improve HO performance indicator (HPI)of the network. The proposed algorithm tunes the hysteresis and time-to-trigger based on exponential averaging of HPI and the average of the old values of the received signal reference power (RSRP). The results show a clear improvement over weighted HPI averaging without RSRP averaging.
