“…In [62], the authors develop a machine learning workflow based on the O-RAN specification and open-source software implementation (O-RAN SC, Acumos, ONAP). The authors of [63] and [64] discuss a possible path for future 5G network slicing integration with multi-access edge computing (MEC). In [65], a new approach based on automatic neighbour relation (ANR) is proposed for minimization of handover failures in an O-RAN based on open interfaces.…”

Open RAN—Radio Access Network Evolution, Benefits and Market Trends

Open RAN (radio access network) movement is perceived as a game changer, having robust potential to introduce shifts in mobile radio access networks towards tailor-made solutions based on the architecture decomposition. It is widely assumed that those changes will affect the approach to network deployments and supply chains of network elements and their further integration and maintenance. First deployments of O-RAN-based networks have already delivered broadband services to end users. In parallel, many proof-of-concept feature evaluations and theoretical studies are being conducted by academia and the industry. In this review, the authors describe the RAN evolution towards open models and make an attempt to indicate potential open RAN benefits and market trends.

“…In addition to the architectural disaggregation and openness (in the sense of interoperability), the aspects of cloudification and virtualisation [1], network slicing [2], [3] and machine learning [4] also play an important role in the Open RAN context. Yet, it is important to emphasize that except for disaggregation and openness, the other aspects such as virtualization and machine learning are not an inherent part of the Open RAN concept.…”

The Open RAN architecture is a promising and future-oriented architecture. It is intended to open up the radio access network (RAN) and enable more innovation and competition in the market. This will lead to RANs for current 5G networks, but especially for future 6G networks, evolving from the current highly integrated, vendor-specific RAN architecture towards disaggregated architectures with open interfaces that will enable to better tailor RAN solutions to the requirements of 5G and 6G applications. However, the introduction of such an open architecture substantially broadens the attack possibilities when compared to conventional RANs. In the past, this has often led to negative headlines that in summary have associated Open RAN with faulty or inadequate security. In this paper, we analyze what components are involved in an Open RAN deployment, how to assess the current state of security, and what measures need to be taken to ensure secure operation.

“…With the arrival of the network softwarization concept, different functionalities in the network adopted a software‐driven approach. Among the most important examples, we can list the Service Based Architecture (SBA) in the network core, 14 and the xApps defined in the O‐RAN controller hierarchy 15 . However, the flexible interaction guaranteed by the open interfaces devised by these approaches are traditionally confined into one specific domain (eg, network functions), while the software landscape in the context of mobile networks is much broader, as discussed next (Figure 2).…”

The ongoing quest for the tight integration of network operation and the network service provisioning initiated with the introduction of 5G often clashes with the capacity of current network architectures to provide means for such integration. Owing to the traditional design of mobile networks, which barely required a tight interaction, network elements offer capabilities for their continuous optimization just within their domain (e.g., access, or core), allowing for a "silo-style" automation that falls short when aiming at closed-loop automation that embraces all the actors involved in the network, from network functions up to the service-provider network functions. To this end, in this paper we make the case for the network-wide capability exposure framework for closed-loop automation by ( ) defining the different entities that shall expose capabilities, and ( ) discussing why the state of the art solutions are not enough to support this vision. Our proposed architecture, which relies on registration and discovery, and exposure functions, allows for enhanced use cases that are currently not possible with state of the art solution. We prove the feasibility of our solution by implementing it in a real-world testbed, employing Artificial Intelligence algorithms to close the loop for the management of the radio access network.
