Abstract

Selon divers aspects, la présente invention concerne, de manière générale, une communication sans fil. Dans certains aspects, un équipement utilisateur (UE) peut déterminer, pour un premier module d'identité d'abonné (SIM) enregistré dans un mode non autonome, si une configuration de livre de codes pour une première cellule est incorrecte pour l'UE, sur la base, au moins en partie, de la transmission d'une demande d'enregistrement pour un service de données de nouvelle radio (NR) à la première cellule. L'UE peut ajouter, pour le premier SIM, la première cellule à une liste d'une ou de plusieurs cellules pour lesquelles des demandes d'enregistrement pour le service de données NR sont interdites. L'UE peut déterminer, pour un second SIM de l'UE, si la première cellule se trouve sur la liste, et transmettre, pour le second SIM, une demande d'enregistrement à une seconde cellule qui n'est pas sur la liste. L'invention concerne de nombreux autres aspects.
