This paper introduces VTT LSA Research Laboratory (VLRL) which is a testbed for dynamic spectrum sharing developed by VTT. The VLRL is a part of VTT’s 5G test network located in Oulu Finland. Main components of the VLRL are Licensed Spectrum Access (LSA) system and Base Station Controller (BSC). LSA system controls the secondary use of the spectrum band owned by another Mobile Network Operator(MNO) and BSC is an software entity that takes care of actual base station configuration when LSA system requires channel occupation or evacuation.The VLRL has been developed over several years in several projects. This paper presents latest incarnation of the environment as it is used in the EuWireless (EuW) project, which aims to develop a platform enabling researchers to perform experiments in a realistic way by combining resources from research networks and commercial MNOs infrastructures. Dynamic spectrum sharing is a significant part of the EuW solution and the VLRL can be used to study and do experiments with the technology.

Cooperative, connected and automated mobility (CCAM) services along different countries require cross-border solutions to support seamless delivery of services in a multi-operator, multi-telco-vendor, and multi-car-manufacturer scenario. The H2020 5GCroCo project will trial 5G technologies in the European cross-border corridor along France, Germany and Luxembourg, as well as in five small-scale trial sites. 5GCroCo analyses three cross-border use cases: tele-operated driving, high-definition map generation and distribution for autonomous vehicles, and anticipated cooperative collision avoidance (ACCA). This paper presents the infrastructure, control architecture, backend software, and end-to-end service orchestration of the cross-border ACCA use case deployed in the Barcelona small-scale trial site.

As 5G standards are completed and technical development of 5G products matures, the pressure for mobile operators to launch commercial networks with advanced capabilities (e.g. network slicing) increases. Despite that, industry forecasts suggest that adoption rates of next-generation networks will be slower compared to previous evolutions. Indeed, unlike 4G, in case of 5G there is i) a novel set of customers, i.e. the verticals, which may bring innovative use cases with unprecedented KPIs, and ii) a confluence of novel technologies, developed across different layers and provided by different vendors. Building, running and operating all of these new innovations is extremely challenging because of the novelty and the lack of previous experience on integrating them altogether. 5G-VINNI project, based on the provisioning of end-to-end network slices for advanced vertical experimentation using a multi-domain 5G facility infrastructure, has born to explore these novelties. This paper addresses the problem of cross-domain slice orchestration, proposing a federated-oriented, standards-based solution to allow transparent interoperability and interworking between different domains, each using a distinct orchestration solution.

In an attempt to assess the suitability of current Infrastructure-as-a-Service (IaaS) technologies for fulfilling 5G-ready applications requirements, this paper has exploited the CNIT S2N testbed to perform a validation over a complete 5G ecosystem. The testbed supports the telecom network platform developed within the MATILDA Project, which adopts the vanilla versions of the main reference projects/software suites in the 5G field, such as OpenStack and Open-Source MANO (OSM). By including such familiar technologies in the 5G ecosystem, vertical industries would interact with a familiar environment similar to today’s scenarios, which would lower the barrier for creating 5G-ready applications.
However, results show that current solutions are blamable for around 99% of the deployment time of applications and network slices, a figure that bumps their lifecycle up to the order of magnitude of minutes proving them still not suitable to fulfill 5G requirements.

The fifth generation (5G) of mobile networks will have to accommodate different types of use cases, each of them with different and stringent requirements and key performance indicators (KPIs). To support this, apart from novel technologies such as network slicing or artificial intelligence, 5G will require a flexible and efficient monitoring system. The collected metrics serve to optimize the performance of the network, and to confirm the achievement of the KPIs. Furthermore, in the envisioned multi-site, multi-stakeholder scenarios, having a common monitoring system is even more critical for an efficient optimization and service provisioning. In this paper, we present a Monitoring architecture for the distribution and consumption of metrics and KPIs for 5G multi-site platforms, where different verticals from different stakeholders are implemented over a shared infrastructure. We also assess the performance of the implemented publish-subscribe paradigm, to confirm that it suits the requirements of these scenarios, and discuss how the architecture could be mapped to other 5G scenarios.
