Abstract
Bursty random access attempts from a huge number of Internet of Things (IoT) devices are potential to cause severe random access collisions and degrade the successful probability of network connection establishment. The 3GPP has provided access class barring (ACB) method for contention resolution. In this paper, we design an implementable contention detection method so that we can activate and deactivate the LTE ACB scheme accordingly. Simulation results show that by applying the proposed scheme, RACH throughput can be significantly improved.
