Noel CRESPI<\/strong>, Directeur de recherche, T\u00e9l\u00e9com SudParis, FRANCE – Directeur de these R\u00e9sum\u00e9 :<\/strong><\/p>\n\n\n\n Alors que la 5G est encore en cours de d\u00e9ploiement, l\u2019attention se tourne vers les technologies Beyond-5G (B5G) et 6G, marqu\u00e9es par une tendance croissante aux r\u00e9seaux locaux et aux solutions de connectivit\u00e9 sur mesure, comme la 5G priv\u00e9e. Ces \u00e9volutions transforment les technologies r\u00e9seau, les r\u00f4les des acteurs (e.g., h\u00f4tes neutres, micro-op\u00e9rateurs) et les mod\u00e8les d\u2019affaires (e.g., mutualisation des ressources, services \u00e0 la demande). Cette th\u00e8se explore les limites de l\u2019architecture standardis\u00e9e de la 5G face aux besoins de d\u00e9ploiements localis\u00e9s et propose une nouvelle architecture pour les r\u00e9seaux B5G\/6G. Elle r\u00e9pond \u00e0 trois axes principaux : 1. Une architecture locale l\u00e9g\u00e8re : adapt\u00e9e \u00e0 des cas d\u2019usage sp\u00e9cifiques (ports, entreprises, campus), int\u00e9grant des fonctions r\u00e9seau compactes et une interconnexion fluide entre les segments radio et c\u0153ur de r\u00e9seau. 2. Une couche de f\u00e9d\u00e9ration bas\u00e9e sur la blockchain : reliant des r\u00e9seaux locaux \u00e0 un r\u00e9seau national via un orchestrateur de services nouvelle g\u00e9n\u00e9ration (SMO), qui g\u00e8re la mobilit\u00e9 et la supervision des services. 3. Un march\u00e9 d\u00e9centralis\u00e9 bas\u00e9 sur les DLT : connectant fournisseurs d\u2019actifs r\u00e9seau et clients \u00e0 la recherche de r\u00e9seaux locaux sous forme de service. L\u2019architecture est impl\u00e9ment\u00e9e avec des technologies open source comme OpenAirInterface et Open5GS pour les fonctions r\u00e9seau, et Ethereum pour la gestion des couches de f\u00e9d\u00e9ration et du march\u00e9 via des contrats intelligents. Les tests en environnement cloud-native montrent que cette approche simplifie les processus et am\u00e9liore l\u2019efficacit\u00e9, la rendant id\u00e9ale pour des d\u00e9ploiements localis\u00e9s et sp\u00e9cialis\u00e9s. Cette \u00e9tude offre ainsi une vision novatrice des r\u00e9seaux B5G\/6G, align\u00e9e avec les \u00e9volutions technologiques et \u00e9cosyst\u00e9miques, r\u00e9pondant \u00e0 la demande croissante pour des solutions de connectivit\u00e9 flexibles et adapt\u00e9es \u00e0 des besoins sp\u00e9cifiques. As 5G continues its rollout, attention is shifting to Beyond-5G (B5G) and 6G technologies, emphasizing local networks and customized connectivity solutions such as private 5G. These trends are reshaping network technologies, actor roles (e.g., neutral hosts, micro-operators), and business models (e.g., resource sharing, on-demand services). This thesis explores the limitations of the current 5G architecture for localized deployments and proposes a new framework for B5G\/6G networks based on three key components: 1. A lightweight local architecture, designed for specific use cases (e.g., ports, enterprises, campuses), with compact network functions and seamless integration between radio and core network segments. 2. A blockchain-based federation layer to interconnect local networks into a broader national network, using a next-generation Service Management Orchestrator (SMO) to handle mobility and service management. 3. A decentralized marketplace, leveraging Distributed Ledger Technology (DLT) to connect network asset providers with clients seeking local networks as a service. The proposed architecture is implemented with open-source tools, including OpenAirInterface and Open5GS for network functions, and Ethereum for federation and marketplace management through smart contracts. Testing in a cloud-native environment demonstrates improved efficiency and simplified processes, making this approach ideal for specialized, localized deployments. This work presents a forward-looking vision for B5G\/6G networks, addressing the growing demand for flexible, tailored connectivity while aligning with technological and ecosystemic advancements.<\/p>\n","protected":false},"excerpt":{"rendered":" L’Ecole doctorale : Ecole Doctorale de l’Institut Polytechnique de Paris et le Laboratoire de recherche SAMOVAR – Services
