Abstract

Procédé et appareil de communication par relais, ainsi que support de stockage et relais. Le procédé de communication par relais consiste à : recevoir des informations d'indication d'accès en provenance d'un équipement utilisateur (UE) à distance, les informations d'indication d'accès étant utilisées pour indiquer le besoin d'accès à un réseau ; lancer directement une requête de récupération RRC ou une requête d'établissement RRC en réponse à la réception des informations d'indication d'accès, ou s'il y a une minuterie d'interdiction d'accès qui est en marche, déterminer, en fonction du type de la minuterie qui est en marche, s'il faut lancer une requête de récupération RRC ou une requête d'établissement RRC, de manière à demander d'établir une connexion RRC pour renvoyer des données ou une signalisation de l'UE à distance. Au moyen de la solution technique selon la présente invention, le taux de réussite d'accès d'un relais pendant l'établissement ou la récupération d'une connexion RRC peut être augmenté.
