Abstract

In LTE-A, it may result in congestion when massive devices initiate almost simultaneously a random access request to the base station, and then the access delay will be increased and the quality of service will be not satisfied. By analyzing the random access model of slotted access, this paper proposed an access congestion control mechanism based on slot access cycle decision adaptively with the estimation of access load. Compared with the slotted-access-based channel access control protocol(SCACP), this paper optimized the choice of slot access cycle to counterbalance the timeslot access load for the sake of access success probability and access delay. Finally, the simulation results demonstrate the effectiveness of the access congestion control mechanism.
