Architecture landscape

The network architecture evolution journey will carry on in the years ahead, driving a large scale adoption of 5th Generation (5G) and 5G-Advanced use cases with significantly decreased deployment and operational costs, and enabling new and innovative use-case-driven solutions towards 6th Generation (6G) with higher economic and societal values. The goal of this chapter, thus, is to present the envisioned societal impact, use cases and the End-to-End (E2E) 6G architecture. The E2E 6G architecture includes summarization of the various technical enablers as well as the system and functional views of the architecture

An adaptive and distributed network selection mechanism for 5G networks

5G networks aim to support a vast amount of data exchange, through network densification, including the integration of multiple radio access technologies (RATs) under a unified radio access and core network. This integration creates a heterogeneous environment where end devices dynamically select the most suitable RAT for consuming a service via a new or even an ongoing communication session. This paper proposes a distributed and adaptive network selection mechanism to address this challenge. The proposed mechanism comprises two co-operating algorithms, one located at the user equipment (UE), and the other at the core network. Its main objective is to satisfy user preferences regarding monetary cost, quality of service, security, energy consumption etc., while safeguarding an operator's traffic engineering policy to avoid congestion. A key feature of the mechanism is the use of a dynamic threshold used to find the sweet spot between a well-balanced access network and maximizing the number of user sessions placed into their most preferred RAT. This threshold is adjusted in real time according to the experienced network conditions. Extensive network performance and quality of experience simulations show that the proposed mechanism accomplishes its objectives and can be used to provide efficient traffic steering decisions. © 2021 Elsevier B.V

Experimentation and 5G KPI measurements in the 5GENESIS platforms

The adoption of 5G has recently picked up pace and across the globe commercial deployments are more and more numerous. In addition to better performance, 5G brings, among others, management and operation flexibility, thus allowing industry verticals to exploit features of the telecommunication networks that go far beyondthe new mobile access capabilities. As with any new technology, the integration, testing and validation of new vertical applications pose great challenges at both management and operational levels. In this context, there is an evident need for 5G infrastructure facilities that offer testing and validation capabilities through aflexible experimentation framework. This paper presents the 5GENESIS EU-funded research project Experimentation Facility and the results of the validation campaigns conducted in its five experimentation platforms. The tests and obtained results were facilitated by the 5GENESIS Suite, an open-source framework providing testautomation and result analytics
