A Novel Group Paging Control Method for Massive MTC Accesses in LTE Networks

Abstract The fifth-generation (5G) systems have to deal with massive deployment of machine-type-communication (MTC) devices. System overload may occur during a random access procedure under limited number preamble resources and physical uplink shared channel especially when there exist MTC devices in cell. In order resolve the system (caused by deployment), 3GPP proposed adopted group paging (GP)-based technique. But its performances dramatically decrease as increases. this paper we propose novel method, named ACB-based control method (AGO). To reduce simultaneous devices, AGO first scatters over GP interval, then automatically adjusts ACB parameters according load conditions. By doing so, achieves high-channel probability for Simulation results show that is superior Pre-backoff mechanisms terms success collision probability, average latency resource utilization rate.
