Abstract

Femtocells enable in-home cell phone (:overage and provide acc,ess to high speed wireless broadband services. The Femtocell network architecture is very different from the existing based on the UMTS macrocell network architecture. Hence, a modified handover procedure for existing networks is needed to support macrocelllfemtocell integrated networks. Voice call services are an essential part of mobile communications and studies of mobile usage show that more than 50 per1cent of all voice calls are placed indoors. Frequent and unnecessary handovers are another problem of heterogeneolls network environments. In this paper" we propose a modified lI:tandover procedure for voice call service between 3GPP UMTS-based macrocell and femtocell networks. And Call Admisision Control (CAC) to reduce the unnecessary handover in the hybrid access mode is proposed.
