The uncontrolled distribution and usage of unmanned aerial vehicles (UAVs) in the world, in combination with the risks associated with aircraft, other property, people’s lives, privacy, violation of secure territories, and overall security, require the creation of a UAV registration and monitoring system. This work aimed to analyze the current state of the UAV registry in Ukraine, to identify the main weak points, and to develop an architecture for the UAV registration and monitoring system. The following tasks were solved to achieve the goal: analysis of the current state of the UAV registry in Ukraine; identifying the main weaknesses of UAV registration and monitoring in Ukraine and determining the directions for their solutions; development of a UAV registration and monitoring method; development of a model for the registration and monitoring of UAVs using 5G cellular networks; development of software for UAVs’ registration and monitoring. As a result of the work, a system was developed that allows registering UAVs when they are turned on and monitoring the current coordinates of the UAVs which are using this system.
The current level of development of the cellular services market, qualitative changes in the means and methods of providing services, and the increased volume and diversity of information circulating in cellular networks have evoked the need for service quality assessment system improvement. To maintain competitiveness, the main efforts of operators are aimed at improving quality and increasing the service life of subscribers in the network by ensuring the required level of customer satisfaction in high-quality services through a system of organizational–technical and socioeconomic measures to bring the achieved level of quality-of-service (QoS) provision in accordance with the existing, emerging, or projected needs of subscribers. To achieve improved QoS provision, a functional relationship between network parameters has been established: The impact of key performance indicators on a key quality indicator through the use of cubic Hermitian splines (CHS) has been determined. The use of splines, as a signal model, can significantly improve the quality of signal processing due to the continuity of values and partial derivatives in the joints of spline gluing. CHS are characterized by calculation simplicity, as they provide high-speed computing, which, in turn, is important for real-time work when processing large data sets. Experimentally, it was shown that the use of splines allows for the ability to calculate statistical estimates of the required parameters of spline approximations, but also their confidence intervals, which increases the accuracy and probability of further calculations and is a distinct advantage of this approach. Also, the methods of service quality management through machine learning have been improved, which are effective tools for modeling integrated indicators of communication services quality control, monitoring their condition in terms of final copies of services, determining the causes of degradation, and reporting. It monitors the service performance provided by the cellular operator. Finally, the method checks the readiness and availability of services, detects network nodes through which quality degradation occurs, collects various quality metrics, and compares them with pre-installed quality indicators.

Welcome to the second edition of the 5G-TOURS newsletter, in which recent milestones and trials will be discussed. Midway through the project, we are swiftly moving from the architecture definition to the implementation of the use cases with some very exciting early demonstrations. Recently, we had our mid-term review where we presented the progress so far and shared the plan for the second half of the project. The first half of the project focused on the definition of the use cases and their technical requirements, the overall architecture that incorporates many components such as 5G-EVE, legacy projects (5G-Monarch and 5G-Xcast) as well as 5G-TOURS specific innovations. The second half of the project will focus on the finalisation of the infrastructure and verticals implementation and subsequently on the use cases validation where the original requirements will be compared with project outcomes. We are also accelerating our dissemination activities by providing videos and webinars on specific use cases while we continue the organisation of workshops and contributions to standards such as 3GPP and specific verticals. This second edition focuses on 8 innovative use cases. Remember to visit our website and our YouTube channel for the latest videos! Enjoy the reading!

With network slicing, operators can acquire and manage virtual instances of a mobile network, tailored to a given service, in this way maximizing flexibility while increasing the overall resource utilization. However, the currently used tunnelling protocol, i.e., GTP, might not be the most appropriate choice for the envisioned scenarios, given its unawareness of the underlay network. In this paper, we analyse the use of an alternative tunnelling protocol to transport user data, namely, Segment Routing IPv6 (SRv6). More specifically, we discuss its qualitative advantages, present a prototype implementation, and carry out an experimental comparison vs. GTP, confirming that it constitutes a valid alternative as tunnelling protocol.
Document Sections I. Introduction II. Evolution of Cloud and Mobile Networking III. Serverless Mobile Architectures IV. Challenges To Address V. Summary Authors Figures References Keywords Metrics Abstract: The softwarization of communication networks provides notable benefits, such as flexibility, improved resource efficiency, and commoditization. In exchange, softwarization requires an increased management overhead and the need to re-design network operation. While the mobile networking ecosystem is currently adapting this new paradigm with other network-related aspects (e.g., network slicing), cloud computing already addressed such problems with the introduction of serverless architectures, also known as Function as a Service (FaaS). With this approach, the software is decomposed into its minimum building blocks, i.e., functions, maximizing scalability, resource efficiency, and flexibility. In this paper, we analyze the potential adoption of the FaaS paradigm by the mobile networking ecosystem, discussing the implicit advantages, the challenges to address, and some solutions to overcome them.

The provision of terrestrial broadcast services using 3GPP technologies was enabled for the first time in LTE Advanced Pro Release (Rel‐) 14, in which the evolved Multimedia Broadcast Multicast Service (eMBMS) technology was enhanced to fulfill a wide set of requirements input by the broadcast industry. During the Enhancements for Television (EnTV) work item in Rel‐14, several modifications were realized affecting system architecture, core, and radio access, which include, an interface to grant control to broadcasters to establish audiovisual services, an application programming interface for developers to simplify access to eMBMS procedures, or a transparent delivery mode with native content formats, among others. At the radio layer, dedicated carriers with 100% broadcast content allocation, and also new OFDM numerologies to support larger intersite distances in Single Frequency Networks (SFNs), were enabled. The most significant change was the so‐called receive‐only mode which enables devices receiving broadcast content without the need for uplink capabilities, SIM cards, or network subscriptions, i.e. free‐to‐air reception. In Rel‐16, 3GPP carried out a study item to evaluate EnTV Rel‐14 against the terrestrial broadcast requirements for 5G defined in 3GPP TR 38.913. Two requirements were detected as not met: the ability to support SFNs with cell radii of up to 100 km and mobile reception with speeds up to 250 km h⁻¹. A Rel‐16 work item standardized further improvements while taking into account practical considerations such as implementation complexity and performance. The improved system is known as LTE‐based 5G Terrestrial Broadcast, and also with the popular name 5G Broadcast.

Network slicing is a key capability for next generation mobile networks. It enables one to cost effectively customize logical networks over a shared infrastructure. A critical component of network slicing is resource allocation, which needs to ensure that slices receive the resources needed to support their mobiles/services while optimizing network efficiency. In this paper, we propose a novel approach to slice-based resource allocation named Guaranteed seRvice Efficient nETwork slicing (GREET). The underlying concept is to set up a constrained resource allocation game, where (i) slices unilaterally optimize their allocations to best meet their (dynamic) customer loads, while (ii) constraints are imposed to guarantee that, if they wish so, slices receive a pre-agreed share of the network resources. The resulting game is a variation of the well-known Fisher market, where slices are provided a budget to contend for network resources (as in a traditional Fisher market), but (unlike a Fisher market) prices are constrained for some resources to provide the desired guarantees. In this way, GREET combines the advantages of a share-based approach (high efficiency by flexible sharing) and reservation-based ones (which provide guarantees by assigning a fixed amount of resources). We characterize the Nash equilibrium, best response dynamics, and propose a practical slice strategy with provable convergence properties. Extensive simulations exhibit substantial improvements over network slicing state-of-the-art benchmarks.

QoE is almost the most important parameter, estimating which it is possible to determine user experience and compare it with users' expectations. Respective method based on the principles of machine learning has been developed to assess and optimize the state of the network in order to improve the quality of service provision to users by cellular operators using the model of service quality control system. Proposed method is a very effective instrument for request formation from users, network status monitoring, service providing quality control integral marks modelling and their optimization, search of degradation reasons and reporting ranging.

5G mobile networks are designed to fulfill very stringent requirements and support new vertical use cases. This transition to a vertical oriented delivery model will have a strong impact in the touristic sector. In this context, the "touristic city node" of 5G-TOURS, built in the city of Turin, aims at exploiting the potential of the media vertical. The objective is to develop an innovative tourism concept based on complementary and linked trials for five specific use cases. The trials will promote an overall integrated indoor/outdoor immersive experience to the visitors using any possible device, enhancing the accessibility to the technology, especially for disadvantaged and disabled people. They will also utilize 5G to drive "remote tourism" based on augmented/virtual reality (AR/VR) experiences and bridge the gap between the physical and virtual worlds for tourism. This paper provides an overview of the 5G technology deployed in the touristic node, explaining the different services to be provided and discussing the need of 5G technology to support this vision. This work also assesses the business potential of each of the considered use cases, corroborating their potential in the context of future network services.

Broadcast is a mechanism created for the delivery of the same content to many users simultaneously. This technology has been considered in 3GPP as part of 4G and recently 5G. One of the key solutions to enhance coverage when using 5G broadcast is the use of Single Frequency Networks (SFN), where all transmitters deliver the same content at the same frequency in a synchronized manner. This paper is derived from the 5G-ROSE project, which works towards the transmission of 5G broadcast services over SFN virtualized networks, using open-source software. The work is divided into three topics. The first part is the development and testing of the first virtualized Multimedia Broadcast Multicast Service over Single Frequency Network (MBSFN) transmission. The second part consists of the introduction of 5G physical layer Release (Rel)-16 specific components. The third part is about the combination of both unicast and broadcast transmissions by means of network slicing. This paper describes in detail the implemented technologies, the testbed facility where these are integrated, as well as the implementation and setup to carry out the experiment.
The fifth generation (5G) of mobile radio technologies has been defined as a new delivery model where services are tailored to specific vertical industries. 5G supports three types of services with different and heterogeneous requirements, i.e. enhanced Mobile Broadband (eMBB), Ultra-Reliable Low- Latency Communications (URLLC) and massive Machine-Type Communications (mMTC). These services are directly related to exemplary verticals such as media, vehicular communications or the Industry 4.0. This work provides a detailed analysis and performance evaluation of 5G New Radio (NR) against a set of Key Performance Indicators (KPI), as defined in the International Mobile Telecommunications 2020 (IMT-2020) guidelines, and provides an overview about the fulfillment of their associated requirements. The objective of this work is to provide an independent evaluation, complementing the Third Generation Partnership Project (3GPP) contribution. From the original group of sixteen KPIs, eleven of them have been carefully selected to cover the three usage scenarios, paying special attention to eMBB services. Results show that 5G NR achieves all considered requirements, therefore fulfilling the specific market’s needs for years to come.

The telecom industry is moving from a "horizontal" service delivery model, where services are defined independent of their consumers, toward a "vertical" delivery model, where the provided services are tailored to specific industry sectors and verticals. In order to enable this transition, an end-to-end comprehensive 5G architecture is needed, with capabilities to support the use cases of the different vertical industries. A key feature of this architecture is the implementation of network slicing over a single infrastructure to provision highly heterogeneous vertical services, as well as a network slicing management system capable of handling simultaneous slices. On top of the network slicing technology, functionality needs to be devised to deploy the slices required by the different vertical players and provide them with a suitable interface to manage their slice. In this article, we design a 5G mobile network architecture to support vertical industries. The proposed architecture builds on ongoing standardization efforts at 3GPP and ETSI, and incorporates additional modules to provide enhanced MANO and control functionality as well as artificial-intelligence-based data analytics. On top of these modules, a service layer is provided to offer vertical players an easyto- use interface to manage their services.
