Handover parameter optimization for self-organizing LTE networks

Self-Organizing Network (SON) mechanism comprises of three components of self-configuration, self-optimization and self-healing which can contribute to optimize the performance of the next generation broadband network such as the Long Term Evolution (LTE) networks. The aim of this study is to propose a self-organizing handover procedure based on the Self-Organizing Network (SON) concept for LTE network. The simulation of the proposed SON-based handover mechanism was conducted using the QualNet software. The two main handover parameters that have been modified are the Hysteresis (Hys) and Time-To-Trigger (TTT). The outcome of the simulation shows the network performance is better after optimizing the Hys and TTT of the handover parameters. The LTE network performance shows remarkable improvement in terms of network throughput, delay and jitter.
