Impact of HandOver parameters on mobility performance in LTE HetNets

In this paper, we analyze the role of HandOver (HO) parameters in improving the mobility robustness in an Heterogeneous Network (HetNet). First, we illustrate the role of offsets in improving the offload of users from macro cell to small cell, while ensuring that overall HO performance is not adversely impacted. Second, we investigate the impact of Time To Trigger (TTT) on the mobility performance in HetNet. We analyze the performance using the HetNet mobility simulator that we have developed as per the guidelines specified in the Release 12 of the Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) standard.
