Abstract

L'invention concerne des systèmes et des procédés de transfert d'informations pour des systèmes de relais. Un premier composant d'un noeud de réseau d'un système de communication WAB (backhaul et accès sans fil) peut recevoir des informations d'état d'autorisation en provenance d'une fonction de gestion de l'accès et de la mobilité (AMF). Un second composant du noeud de réseau peut envoyer des informations d'identité et/ou une indication associée aux informations d'état d'autorisation à l'AMF.
