The provision of high data rate services to mobile users combined with improved quality of experience (i.e., zero latency multimedia content) drives technological evolution towards the design and implementation of fifth generation (5G) broadband wireless networks. To this end, a dynamic network design approach is adopted whereby network topology is configured according to service demands. In parallel, many private companies are interested in developing their own 5G networks, also referred to as non-public networks (NPNs), since this deployment is expected to leverage holistic production monitoring and support critical applications. In this context, this paper introduces a 5G NPN architectural approach, supporting among others various key enabling technologies, such as cell densification, disaggregated RAN with open interfaces, edge computing, and AI/ML-based network optimization. In the same framework, potential applications of our proposed approach in real world scenarios (e.g., support of mission critical services and computer vision analytics for emergencies) are described. Finally, scalability issues are also highlighted since a deployment framework of our architectural design in an additional real-world scenario related to Industry 4.0 (smart manufacturing) is also analyzed.

Ongoing evolutions in the Network Function Virtualization (NFV) area show that software will play an increasingly important role within the telecommunication industry. It enables telco providers to faster introduce telecom services, combined with new possibilities to optimize and fine-tune operational performance. New virtualization and softwarization methods support fine-grained scaling of resources and highly-customizable configuration settings. Additionally, multi-datacenter topologies are available to deploy the Virtual Network Functions (VNFs) a service consists of. In this context, specialized tools are needed for debugging and validating the deployment, placement, chaining, configuration and scaling of network services, before the operator deploys the service in production. This demo showcases an opensource Software Development Kit (SDK), built to support NFVbased services throughout their whole lifecycle. During the demo, several example VNFs will be loaded into the SDK environment to demonstrate the features a service developer is envisioned to use, while either creating or updating NFV-based telecom services.

Nowadays, we are ready to have precommercial Cooperative Intelligent Transport Systems (C-ITS), nevertheless there exist challenging functional and security aspects that need to be addressed. One of them is the fact that, in every era, there will be several radio technologies which will be used by vehicles that need to be connected between them, therefore, the systems needs to provide interoperability services. The other critical issue is to reinforce security against attacks on localization receivers or in vehicles equipment. Most of these functions are based in a large amount of computation power, to this end, this paper presents the approach taken by H2020 CARAMEL project, using a Multi-access Edge Computing (MEC) that could provide the necessary performance assets.
