THE PERFORMANCE OF HANDOVER SCENARIO FOR MACROCELL AND FEMTOCELL IN LTE HETEROGENEOUS NETWORK

Seamless handover process between macrocell and femtocell base stations is a major challenge of LTE femtocell-macrocell integrated system because the need of an efficient handover which can transfer User Equipment (UE) between femtocell and macrocell. The challenge facing today and future is to provide seamless handover initiation scheme and better signal strength to users because of the different LTE heterogeneous network. So, the deployment of femtocells can offload traffic from the LTE macro cellular to be managed by the femto cellular network. This research presents the handover performance when the femtocells are deployed on the macrocell heterogeneous network and also LTE femtocell-macrocell integrated network scheme for hand-in and hand-out handover process. The simulation results show a significant reduction in number of handover calls rate with the proposed scheme which can manage overloaded traffic in the LTE heterogeneous network.
