“…The approaches to resolve the RA overload problems can be categorized into PA collision mitigation [4], PUSCH resource collision avoidance [5], PUSCH resource reuse mechanism [6], [7], and access class barring (ACB) [8], [9]. Various RA schemes for access prioritization were proposed based on pricing-based load control [10] and PA allocation [11].…”

Abstract-In this paper, we propose a preamble (PA) collision resolution (PACR) scheme based on multiple timing advance (TA) values captured via tagged PAs. In the proposed PACR scheme, tags are embedded in random access (RA) PAs and multiple TA values are captured for a single detected PA during a tag detection procedure. The proposed PACR scheme significantly improves RA success probability for stationary machine nodes since the nodes using collided PAs can successfully complete the corresponding RAs using exclusive data resource blocks.

“…(c) Collision reduction in the RACH: Access Class Barring (ACB) and Enhanced Access Barring (EAB) schemes [7]- [10], [19], [25] decrease the collisions in the RACH at the expense of higher access delay, by placing devices in different classes with different connection priorities, controlled by different access probabilities (APs). Network access is then controlled by adapting the APs.…”

Abstract-Machine Type Communications (MTC) collectively refers to the exchange of data among devices that operate without human intervention. A significant number of such devices are currently served by cellular networks, and that number is expected to grow in the near future. However, cellular networks, including current fourth generation LTE networks, face several challenges when it comes to handling MTC traffic as they were primarily designed for Human Type Communications (HTC) which have very different traffic patterns. In this paper we focus on periodic MTC devices, such as sensors and meters, which cause significant signaling load and increased collisions over standard LTE networks. We propose ASPIS, a holistic mechanism designed to overcome these problems. ASPIS reduces the signaling load by partly preserving a device's connection to the network in conjunction with a new Random Access process and efficient support for short message transmissions. In addition, it uses a proactive preamble split scheme to alleviate collisions. ASPIS is easy to implement without requiring hardware changes while at the same time maintains security and can be incrementally deployed alongside legacy devices/infrastructure. We showcase the practicality of ASPIS by implementing it on the OpenAirInterface platform. Further, we demonstrate its effectiveness through extensive evaluations via a combination of small-scale experimental evaluation and large-scale, realistic simulations.

“…In [6], [7], the load of RAN is predicted so that the access barring parameter can be determined by the network. The authors preallocated random access resource for different MTC classes to prevent devices from accessing network at the same time [8]. In [9], the authors used Access Class Barring and timing advance information to relieve the random access load.…”

Abstract-Collecting data from a tremendous amount of Internet-of-Things (IoT) devices for next generation networks is a big challenge. A large number of devices may lead to severe congestion in Radio Access Network (RAN) and Core Network (CN). 3GPP has specified several mechanisms to handle the congestion caused by massive amounts of devices. However, detailed settings and strategies of them are not defined in the standards and are left for operators. In this paper, we propose two congestion control algorithms which efficiently reduce the congestion. Simulation results demonstrate that the proposed algorithms can achieve 20∼40% improvement regarding accept ratio, overload degree and waiting time compared with those in LTE-A.
