A New Call Admission Control Strategy for LTE Femtocell Networks

This paper introduces a call admission control (CAC) strategy for LTE femtocell networks supporting multimedia services with different classes of traffic and diverse bandwidth requirements. In this work, the multi-service CAC strategy composes of two parts: subscriber authentication and queuing admission control. Theoretical analysis and simulation are performed on three key principles. Comparing with the typical strategy, simulation results indicate that better probabilistic connection-level QoS parameters are achieved by using the proposed strategy.
