英文摘要 | MTC (Machine-Type Communication) applications are known as an indispensable part of the future internet and they have received considerable research attentions. In MTC, a huge amount of MTC devices try to transmit data to eNB within a very short period of time. It brings about RAN (Radio Access Network) overload issue. To tackle the issue, 3GPP specifies ACB (Access Class Barring) as an overload resolution mechanism but it is still open issue to control ACB parameters autonomously. We propose a control mechanism of ACB parameter based on the predicted traffic load. In general, prediction accompanies inevitable approximation error. Our mechanism determines ACB parameter by considering the predicted traffic load and approximation error simultaneously. Simulation results show that the proposed mechanism increases the number of successful devices, and decreases the number of failed devices and access delay. |
