Radio Admission Control (RAC) is a key function of the Radio Resource Management (RRM) at layer 3 of an eNodeB; however, the 3GPP standard does not specify the RAC and is left as an eNodeB vendor specific. Most admission control schemes proposed to date do not ensure differentiation among the users at different priority levels. Also, they do not provide fairness among the users with the same priority. This paper proposes a novel RAC scheme for Long Term Evolution (LTE-Advanced) networks based on the combined idea of complete sharing and virtual partitioning. It introduces a step wise degradation scheme, to prioritize the high priority traffic in state of resource limitations.
A detailed and comprehensive simulation is performed in Opnet to show the efficiency of the proposed RAC scheme. The simulation results demonstrate that the proposed RAC scheme minimizes the call blocking probability and adheres extremely well to the bandwidth constraints of different traffic types.
