EPC signaling load impact over S1 and X2 handover on LTE-Advanced system

A small cell is one of key factors in a Long Term Evolution (LTE) and LTE-Advanced (LTE-A) system. its handover signaling load impact on the evolved packet core (EPC) network is a big issue when considering a benefit and efficiency of S1 and X2 handover (HO) in diverse handover scenarios due to tons of small cells. Therefore, the performance of the inbound handover signaling load on the control plane in EPC network with deployed home eNB (HeNB) has been analyzed and compared in this paper.
