Abstract
In this paper we propose a new horizontal handover
oscillation control algorithm for Long Term Evolution (LTE)
Self-Optimizing based Networks (SON). Based on a preestablished
policy, this algorithm automatically adjusts the
Hysteresis and Time-To-Trigger (TTT) based on Ping-Pong
Handover Performance Indicator (HPI). Additionally, the User
Equipment (UE) type of traffic and speed is taken into account
for a more accurate handover decision. Results show clear
improvements when compared with other proposals, namely the
fixed parameter scenario.
