Abstract

Dans ses modes de réalisation, la présente invention se rapporte à un procédé d'établissement de porteuse, à une station de base, et à un équipement d'utilisateur (UE). Le procédé selon l'invention consiste : à transmettre un message mixte à une station de base, le message mixte comprenant une demande de connexion pour la gestion des ressources radioélectriques (RRC) et une demande de service ; à retransmettre le message mixte à la station de base si une horloge de résolution de conflits d'accès située au niveau de la couche de contrôle d'accès au support (MAC) expire, et si une première valeur de comptage est inférieure au nombre maximum de retransmissions du message mixte ; à transmettre un message commun à la station de base si l'horloge de résolution de conflits d'accès qui est située au niveau de la couche MAC expire, et si la première valeur de comptage est égale ou supérieure au nombre maximum de retransmissions du message mixte. Le message commun contient la demande de connexion RRC mais pas la demande de service, et la première valeur de comptage correspond au nombre de fois où le message mixte est transmis à la station de base. De cette manière, quand le mode de fonctionnement parallèle de l'UE n'est pas opérationnel, le mode de fonctionnement série peut être réactivé. La compatibilité est ainsi garantie de façon fiable entre un fonctionnement parallèle et un fonctionnement série, et le taux de réussite de l'établissement d'une porteuse augmente.
