Abstract

L'invention concerne un procédé de traitement d'un processus d'accès aléatoire, ainsi qu'un dispositif terminal et un dispositif réseau. Le procédé de traitement d'un processus d'accès aléatoire est appliqué au dispositif terminal. Le procédé consiste à : dans un état non connecté, au cours d'un processus d'accès aléatoire, envoyer une séquence de préambule d'accès aléatoire cible pour demander à un côté réseau d'attribuer, au dispositif terminal, une ressource de liaison montante qui n'est pas inférieure à une première valeur prédéfinie, la ressource de liaison montante étant utilisée pour rapporter des informations de liaison montante dans le processus d'accès aléatoire.
