On Radio Admission Control for LTE Systems

Free registration required

Executive Summary

Admission Control (AC) is an important feature in a wireless network by which radio resource usage is optimized whilst maintaining the Quality of Service (QoS) of existing users. In this paper, a novel admission control mechanism is proposed for the Long-Term Evolution (LTE) cellular networks. Simulation results show that the proposed AC can provide a more flexible trade-off between network and user performances compared to simpler approaches based on resource utilisation. It is also shown that a predictive approach provides a significant overall network performance gain at the expense of cell-edge blocking.
