2018年8月4日 · To reduce the burstiness of the connection requests in heavy traffic situations, access class barring (ACB) is proposed in the 3GPP standard. Using ACB, an MTC device …

2018年10月18日 · Supporting trillions of devices is the critical challenge in machine type communication (MTC) communications, which results in severe congestions in random access …

2018年9月1日 · We present a multiple data packets transmission scheme based on the Access Class Barring (ACB) and multiple granted Resource Blocks (RBs) to further reduce the MTC …

In this paper, we present a unified analytical framework to analyze the performance of the fixed ACB scheme for a simple random access procedure (i.e., one-shot transmission model) in …

Download scientific diagram | System model of MTC in LTE and activation procedure in the ACB scheme from publication: Overload control in the network domain of LTE/LTE-A based …

2016年8月17日 · ACB-based mechanisms distribute the access attempts based on the barring factor. It effectively reduces the collision probability under large transmissions at the same …

2024年10月27日 · Access Class Barring (ACB) technology is employed in overload control. When the system is overloaded, the ACB factor adjusts its size based on the number of accessed …

In this paper, we propose an annulus-based ACB (AB-ACB) scheme and combine it with TA command comparison in stationary MTCDs scenario. Aiming to exploit the devices distribution …

2019年10月11日 · The traditional ACB scheme sets a fixed barring factor during the network access process of MTCDs. A traffic-aware ACB is proposed in to relieve the access delays …

Supporting trillions of devices is the critical challenge in machine type communication (MTC) communications, which results in severe congestions in random access channels of …
