摘要

In contrary with the seamless connectivity in a telecom network, successful hand over (HO) of the user from one cell to another is an important factor that affects the network performance. The two popular HO model named as Margin Based Hand over (MBH) and Quality Based Hand over were designed for the existing LTE networks. In this paper, we discuss the performance of both models in comparison with a proposed model named as OPtimum Quality and Margin Based Hand over (OPQMBH). The Hand over decision-making algorithm work on tradeoffs between the margins and quality of the signal. To validate HO simulations were done on the proposed model for Long Term Evolution (LTE) network at different UE mobility speed using the network simulator NS3. Numerical results show that proposed model outperforms in comparison with the existing model in terms of HO count, throughput and link quality. The proposed OPQMBH model reduces the signaling load and resource blocking that improves the performance of LTE network.
