An analytical model is presented to investigate the performance of the EAB algorithm on the RACHs in LTE-A networks and the optimal values of paging cycle and repetition period of system information block type 14 (SIB14) can be obtained from the analytical model subject to a target quality-of-service (QoS) constraint.Abstract:
Simultaneous channel accesses from mass machine-type communications (MTC) devices may congest the random-access channels (RACHs) of LTE-A networks. Currently, 3GPP selects extended access barring (EAB) mechanism as the baseline solution to relieve the congestion of RACHs by barring low-priority devices. Different settings of EAB parameters may re-shape the arrival process of MTC traffic and thus, lead to unpredictable performance. This paper presents an analytical model to investigate the performance of the EAB algorithm on the RACHs in LTE-A networks. Computer simulations were conducted to verify the accuracy of the analysis. The optimal values of paging cycle and repetition period of system information block type 14 (SIB14) can then be obtained from the analytical model subject to a target quality-of-service (QoS) constraint.read more

Prioritized Random Access with dynamic access barring for RAN overload in 3GPP LTE-A networks
TL;DR: Simulation results show that, unlike Extended Access Barring (EAB) and the current LTE-A medium access control (MAC) scheme, the proposed PRA architecture with the DAB scheme guarantees QoS, i.e., high success rate and low access delay, even under the worst case RAN overload in LTE-B networks.
