(FR) MODÈLE ET ARCHITECTURE DE SYSTÈME POUR ACCÈS INTÉGRÉ MOBILE ET LIAISON TERRESTRE DANS DES RÉSEAUX AVANCÉS
Abstract
(EN)
Facilitating operation and support of mobile relays based on an integrated access and backhaul concept for advanced networks (e.g., 4G, 5G, 6G, and beyond) is provided. An embodiment relates to a communication network architecture that can comprise a control plane architecture of a relay node device. The control plane architecture can comprise a star-type architecture. Further, the communication network architecture can comprise a user plane architecture of the relay node device. The user plane architecture can be separated from (or independent of) the control plane architecture. Further, the user plane architecture can comprise a multi-hop architecture. The relay node device can be configured to operate according to a fifth generation wireless network communication protocol, or other advanced communication protocols.

La présente invention a pour objet de faciliter un fonctionnement et une prise en charge de relais mobiles sur la base d’un concept d’accès intégré et de liaison terrestre pour des réseaux avancés (par exemple, 4G, 5G, 6G et au-delà). Un mode de réalisation concerne une architecture de réseau de communication qui peut comprendre une architecture de plan de commande d’un dispositif de nœud relais. L’architecture de plan de commande peut comprendre une architecture de type en étoile. Par ailleurs, l’architecture de réseau de communication peut comprendre une architecture de plan d’utilisateur du dispositif de nœud relais. L’architecture de plan d’utilisateur peut être séparée (ou indépendante) de l’architecture de plan de commande. Par ailleurs, l’architecture de plan d’utilisateur peut comprendre une architecture à multiples sauts. Le dispositif de nœud relais peut être configuré pour fonctionner selon un protocole de communication de réseau sans fil de cinquième génération ou selon d'autres protocoles de communication avancés.
