Handover Scheme in LTE-based Networks with Hybrid Access Mode

Abstract

Femtocell networks that use Home evolved NodeB (HeNB) and existing networks for backhaul connectivity can fulfill the upcoming demand for high data rates in wireless communication systems as well as extend the coverage area. We consider some parameters for handovers, including interference, velocity, RSS and quality of service (QoS) level. We propose a new handover strategy between the femtocell and the macrocell for LTE (Long Term Evolution) -based networks in hybrid access mode. This strategy can avoid unnecessary handovers and can reduce handover failure. In this paper, we analyze three scenarios for handover decision strategy procedures: hand-in for Closed Subscriber Groups, hand-in for non-Closed Subscriber Groups, and hand-out.
