Call admission control scheme for LTE femtocell-macrocell integrated system

The femtocell technology is a quick and intelligent solution to augment the system capacity and to meet the high demand of services on broadband wireless access, the deployment of femtocells has been proposed to offload large quantity of user data traffic from the macrocellular network to the femtocell and expand the limited coverage of the macrocell in mobile networks. Switching seamlessly between the macrocell and femtocell networks is a major challenge for LTE femtocell-macrocell integrated system.
