Abstract :
In this paper, we investigate issues related to the estimation of user´s mobility state in the Long Term Evolution (LTE) heterogeneous cellular network. We discuss the need of such estimation and further, we propose an enhancement to the existing Mobility State Estimation (MSE) procedure which results in reduced HandOver failures. We also analyze the role of thresholds in mobility state estimation and their impact on the mobility performance. We analyze the performance using the Heterogeneous Network (HetNet) mobility simulator that we have developed as per the guidelines specified in the Release 12 of the Third Generation Partnership Project (3GPP) LTE standard.
