In the context of machine type communications (MTC), the control of the Radio Access Network (RAN) is becoming a topic of major concern. In fact, a massive number of MTC devices simultaneously perform random access (RA), causing severe overload in the Random Access Channels (RACH), which significantly reduces RA success probability. To control the RAN overload and alleviate the access network congestion, 3GPP developed the Access Class Barring (ACB) procedure ...
