Deliverable D2.3 Technical requirements of the use cases, economic and deployment implication

5G-TOURS responds to the 5G PPP ICT-19-2019 Advanced 5G validation trials across multiple vertical industries call, whose main goal is to achieve the European 5G Vision of 5G empowering vertical industries closer to deployment. The project is implementing a set of use cases with the objective of improving the quality of life in a city, as well as the experience of the tourists visiting that city. Grouped in 3 different themes, 5G-TOURS has deployed end-to-end trials in real environments, each theme in a different trial site: 1) Turin, the touristic city; 2) Rennes, the safe city; and 3) Athens; the mobility-efficient city. In concrete, thirteen different use cases are being addressed, each of them with a specific purpose, different stakeholders and users, a variety of technologies, etc. This document provides a standard framework for presenting the various aspects of these diverse use cases, including a complete description of each of the use cases, not only from a functional point of view, but also from technical, deployment and economical perspectives. For each of the use cases, it provides: • A final description of the functionality of the use case. This description is the result of the refinement and continuous analysis of the use cases during the project lifetime. • Updated sequence diagrams that enrich such descriptions by defining the flow of events and interactions of the key actors with the 5G-TOURS infrastructure. • Final use case specific user and network requirements. This deliverable includes a reviewed version of the initial requirements provided by the verticals and that were presented in deliverable D2.2 as well as their analysis. The same methodology has been used, but with a better knowledge and understanding from the teams, acquired as the developments and the first implementations of the use cases evolved. • GSMA Network slice Types (NEST), a novelty introduced by the GSMA and used in this deliverable that provides a standard technical formulation of how verticals should explain their requirements to network operators. Although the definition of the user and network requirements, the methodology and templates used in the project for their collection, normalization and analysis were explained in the previous deliverable D2.2, the approach followed is summarized again in this deliverable for the benefit of the reader. The relationship of these requirements with the KPIs being used in the project to evaluate the use cases and the 5G PPP KPIs is also explained. 5G-TOURS uses and extends the 5G-EVE platform in order to support its use cases. Therefore, additionally to the user and network requirements, the use cases also introduced some system requirements that helped to identify how the 5G-EVE infrastructure has to be enhanced for the successful deployment of these use cases. The enhanced functionality developed by the project is also briefly introduced in this deliverable, as well as an analysis of the dependences, deployment implications and interactions. Before presenting the different use cases, we describe the specific site into which the use cases are being deployed, describing its main functionalities and peculiarities with respect to the other two, and analysing the particular deployment implications. Finally, the economic drivers for the commercial deployment of 5G-TOURS use cases are analysed. For that, we first introduce the framework for understanding economic and commercial potential of the 5G-TOURS use cases and then the evaluation cases used for assessing benefits and commercial exploitation. Finally, the approach and results for our assessment of the economic benefits of different specific settings are presented, including the key findings from benefits analysis across evaluation cases.
