Abstract :
The femtocell networks that use Home eNodeB (HeNB) and existing networks as backhaul connectivity can fulfill the upcoming demand of high data rate for wireless communication system as well as can extend the coverage area. Hence the modified handover procedure for existing network is needed to support the macrocell/femtocell integrated network. Frequent and unnecessary handover is another problem for hierarchical network environment that must be optimized to improve the performance of macrocell/femtocell integrated network. In this paper, we propose a modified handover procedure between macrocell and femtocell. An asymmetric handover scheme using Double Threshold Algorithm (DTA) and Call Access Control (CAC) is proposed to reduce the unnecessary handovers.
