Hysteresis Margin and Load Balancing for Handover in Heterogeneous Network

Ranada Prasad Ray and Lun Tang
Abstract—Long term evolution (LTE) heterogeneous network can represent improvement of cell coverage and network capacity by adopting advanced physical layer techniques. In heterogeneous network, one of the major challenges is the handover decision between different eNBs. The utilization of the picocells results to use more network resources and handover procedure. In this paper, we investigate the hysteresis margin and load balancing problem in a 3GPP LTE heterogeneous network. Firstly, we consider A3 event, Hysteresis Margin (HM) and Cell Individual Offset (CIO) objectives are not fixed for every cells. Then we analyze the complexity of the problem and propose a practical algorithm which calculate adaptive hysteresis margin and load balancing in heterogeneous network. The results show that our algorithm can lead to significantly better performances, such as redundant handovers reduction and improvement of the network performance.

Index Terms—LTE heterogeneous network, hysteresis margin, cell individual offset, load balancing.
