摘要：This paper presents a novel Handover mechanism to minimize target Femto Access Points (FAPs) listduring macro-to-femto and femto-to-femto handover in LTE based Macro-Femto Heterogeneous Networks.HandOver is the procedure that transfers an ongoing call from one cell to another as the users movethrough the coverage area of cellular system. The femtocell has a limited coverage area (15 meters to 30meters), and subsequently, HandOver is decided based on mobile User Equipment (UE) speed for handoverbetween macrocell-to-femtocell and femtocell-to-femtocell. In the existing networks, for handoverprocedure, serving Base Station will decide the cell selection based on mostly the signal strength of theneighbouring femtocells. This information is provided by the Measurement Reports sent by thecorresponding UE. In this paper, we present a novel handover management scheme which considers boththe Received Signal Strength and Cell Load of the target Femtocells for making the Handover decision.This proposed scheme for macro-femto heterogeneous network reduces the number of target FAPs to avoidhandover to overloaded femtocells and also reduce the number of handovers.
