This report provides the final update out of four planned for the 5G-TOURS project presenting work performed in WP3 "Network architecture and deployment". The scope of this deliverable is to report on the overall progress made in the 5G-TOURS network and system architecture and innovative technologies for the 5G network deployment in three trial sites (Turin, Rennes, and Athens). This report focuses on the following aspects: • Finalization of the baseline network architecture which encompasses 5G EVE platform, relevant standards components and 5G-TOURS innovations, as well as architecture instantiation per trial site and interactions with vertical players. • The technology evolutions conceived in the 5G-TOURS project, their implementation results, Service Layer components and theirs SDK descriptions. • The final set of the network infrastructure deployments on each trial site. In particular, several important outcomes from the architectural work, network innovations and trial deployments can be highlighted. Firstly, a comprehensive architectural setup was designed to suit vertical actors’ needs, facing 5G-TOURS Service Layer (which integrates useful network exposure functions for the service “closed loop” e.g. KPI monitoring), incorporating 5G EVE interworking gear (for service onboarding through 5G EVE portal) and/or direct connection to local MANO functions (where exposure of specific functionalities is needed directly towards the Service layer). Then, specific 5G-TOURS network innovations were devised, such as Artificial Intelligence functions for network resource forecasting, dynamic slicing and orchestration support (showcased through successful Proof-of-Concept demos prepared by several partners), some others directly integrated within a selection use cases, e.g. state-of-the-art solution for the 5G broadcast support (in Turin site), Enhanced MANO extensions (largely deployed in Athens trial). Also, open-source initiatives were developed for the Service Layer to support some of these technologies, with SDK and API documentation, and release of full open-source software solutions and largely publicized, e.g., AI Agents for OSM. Finally, thorough design and deployment of complex network setup was achieved in three trial sites, integrating equipment, system solutions and application software from different suppliers towards in-the-field realization of a set of distinct use cases which improve citizen lives: media and touristic applications in a world heritage protected environment (Turin site), novel 5G mmWave radio solution and eHealth appliances' integration within restricted hospital environment (in Rennes site, one of the first experimental eHealth deployments in Europe), mobilityefficient city applications with full integration of diagnostic / network measurement extensions to achieve "closed loop" between Service layer and networking (in Athens site).
