Artificial Intelligence (AI) is widely applied in telecommunications to enable zero-touch automation in network operation and service management. Due to the high complexity, deploying advanced AI mechanisms is not always feasible inside the operator’s network domains. Instead, via service exposures, it becomes possible for vertical customers to integrate their external AI solutions with the network and service management system to form a closed loop (CL) and contribute to the automation process. In this paper, we propose an exposed CL model based on service exposure and apply it to automate service assurance tasks like autoscaling in a network function virtualization (NFV) system orchestrated by ETSI Open Source MANO (OSM). A testbed is built to validate the model. It collects monitoring data from the OSM monitoring module and external monitoring tools. Vertical customers drive and customize their AI solutions to aggregate these data sets and run analytics to detect and predict anomalies prepared for scaling. Preliminary analysis demonstrates the added values of customer-driven monitoring and analysis via the exposed CL.

5G networks provide novel features that have generated huge expectations for industry and society. Therefore, its implementation and validation become crucial. In this context, one of the most important parameters that need to be designed, implemented and tested is security. This paper takes advantage of the real 5G implementation made under the EU-Horizon 2020 5G-VINNI project, and specifically presents the security policies in the operational 5G-VINNI Norway facility. This paper uses as reference the CIA Triad model for the development of security policies, in order to present the concepts in an organized and structured way. In short, the main point of this paper is to present how the 5G-VINNI Norway facility offers availability, confidentiality and integrity to the services provided to 5G-verticals.


Evaluation of Live Video Streaming Performance for Low Latency Use Cases in 5G

This paper introduces the practical evaluation setup of the low latency video streaming system for extensive performance measurements using 5G test network. The results gathered with the latest 5G new radio indoor equipment enriched with the optimized streaming solutions and accurate measurement system reveal the bottlenecks in the mobile transmission path especially in uplink channel, and help to identify the places of improvement. These places of optimization are essential in the live low latency streaming scenarios of the different industries moving to wireless technologies in vehicle-based connectivity, such as streaming vital information from an ambulance to a receiving hospital, transmitting highly prioritized traffic or road information to other drivers, or streaming through congested mobile network in need of rapid adaptation. Furthermore, the experimental knowledge gained during the extensive measurements in real 5G test environment have demonstrated the application-based processing delay to have substantial effect on the total end-to-end latency. The ongoing 5G standardization and its actualization by the operators already enables eMBB and URLLC for extreme high throughput and low latency streaming, but practical field research and evaluation is needed especially for sending time critical data to uplink direction from moving vehicles in the harsh signal environment. For better understanding of the requirements in low latency video streaming and planning the actual vehicle to network scenarios over 5G, it is essential to identify the current performance and possible restrictions before shifting to more complex system development.


VITAL-5G: Innovative Network Applications (NetApps) Support over 5G Connectivity for the Transport & Logistics Vertical

As 5G networks are being deployed across the world, more and more vertical industries are discovering the benefits of 5G connectivity and the novel business and innovation models that it has to offer. The Transport & Logistics (T&L) industry is expected to be one of the key adopters of 5G technology, where the 5G enterprise market for T&L is estimated to reach $2.9 trillion (€2.7 trillion) by 2026 and grow at a CAGR of 47.5% [1]. However, the adoption and penetration of 5G-based solutions in T&L may be hindered by the knowledge/expertise gap between the vertical industry, the telecommunication experts and the application developers. 5G based Network Applications (NetApps) represent a key enabler for the adoption of 5G solutions, as they can abstract the complexity of the underlying 5G infrastructure for T&L application developers, and significantly reduce the service creation and deployment times, as well as optimize the utilization of 5G resources. The European Innovation Action project VITAL-5G has the vision to advance the offered T&L services by showcasing the benefits of 5G-based NetApps via real-life trials over state of the art vertical (T&L) facilities (warehouse, hubs, ports) and advanced European 5G-testbeds. To support both internal and 3rd-party experimentation, VITAL-5G will create an elaborate experimentation service portal and online repository which will facilitate the creation, deployment, monitoring and (re)configuration of NetApps in the vertical environment.
