Summary:Slotted-access-based channel access control protocol (SCACP) is one of the solutions proposed by 3GPP to deal with the congestion of the random access channel (RACH) resulted from mass access machine devices. This paper proposes an analytical model to investigate the performance of the SCACP for LTE-Advanced networks. An access cycle decision algorithm is then presented to set the optimal access cycle of SCACP to maximize the utilization of RACHs subject to a given quality of service (QoS) constraint of human traffic. Numerical results demonstrate the accuracy of the proposed analytical model and the effectiveness of the access cycle decision algorithm.
