“…In addition, several studies show that the GSM radio access network faces serious capacity issues in the presence of the synchronized access of a massive number of MTDs [12][13][14]. As a consequence, there has been an effort in 3GPP to further enhance the GSM related standards to facilitate the support of MTC.…”

The next generation of communication systems, which is commonly referred to as 5G, is expected to support, besides the traditional voice and data services, new communication paradigms, such as Internet of Things (IoT) and Machine-to-Machine (M2M) services, which involve communication between Machine-Type Devices (MTDs) in a fully automated fashion, thus, without or with minimal human intervention. Although the general requirements of 5G systems are progressively taking shape, the technological issues raised by such a vision are still partially unclear. Nonetheless, general consensus has been reached upon some specific challenges, such as the need for 5G wireless access networks to support massive access by MTDs, as a consequence of the proliferation of M2M services. In this paper, we describe the main challenges raised by the M2M vision, focusing in particular on the problems related to the support of massive MTD access in current cellular communication systems. Then we analyze the most common approaches proposed in the literature to enable the coexistence of conventional and M2M services in the current and next generation of cellular wireless systems. We finally conclude by pointing out the research challenges that require further investigation in order to provide full support to the M2M paradigm.

“…LTE-A systems with MTC devices may receive nonsynchronized (uncorrelated) requests or requests that are highly synchronized (correlated), e.g., when a large number of machines try to simultaneously connect in a burst, e.g., after a power outage, or when many sensors respond to a common event [33]- [36]. We have conducted evaluations for a Poisson arrival process modeling uncorrelated requests and Bernoulli process and Markov-modulated Poisson process (MMPP) arrivals modeling correlated arrivals.…”

The connection establishment in Long-Term Evolution Advanced (LTE-A) is often executed for distributed user equipment (UE) nodes with frequent small data sets for transmission to the central enhanced Node B. LTE-A connection establishment consists mainly of an access barring check (ABC) followed by preamble transmission (contention). Previous studies of connection establishment have often assumed Poisson characteristics (without verifying the Poisson assumption). In this paper, we introduce a simple equilibrium analysis framework for comprehensively evaluating the LTE-A connection establishment, including both access barring and preamble contention. We conduct a detailed analysis of the backlog arising from the uniform backoff over up to T max o slots by UE requests that failed the barring check or collided in the preamble contention. We verify that the process representing the numbers of backlogged UE requests rejoining the connection establishment tends to Poisson process characteristics for high barring probability and long maximum timeout T max o . We present numerical comparisons of our equilibrium model with simulations for practical parameter settings. The comparisons illustrate the effects of the parameter settings on the convergence of the LTE-A connection establishment dynamics to Poisson characteristics for nonsynchronized and synchronized request arrivals.

“…The focus of the further text is on the limitations present in AGCH and DATA stages and the methods how to overcome them by MAC protocol reengineering. 2 A typical configuration foresees that 7 out of 11 blocks of the signaling PDCH are dedicated to AGCH, providing capacity to send approximately 30 AGCH messages per second [8]. However, as shown in Section VI, this configuration is inadequate for the referent scenario with a high density of low-rate devices, as a single cell cannot deliver enough AGCH messages within the time required to grant all resource requests.…”

GSM is a synonym for a major success in wireless technology, achieving widespread use and high technology maturity. However, its future is questionable, as many stakeholders indicate that the GSM spectrum should be re-farmed for LTE. On the other hand, the advent of smart grid and the ubiquity of smart meters will require reliable, long-lived wide area connections. This motivates to investigate the potential of GSM to be evolved into a dedicated network for smart metering. We introduce simple mechanisms to reengineer the access control in GSM. The result is a system that offers excellent support for smart metering, as well as the other massive machine-to-machine traffic patterns that are envisioned in 3GPP.
