Abstract

La présente invention a trait à un procédé et un terminal de transmission de requête d'accès de liaison montante par un utilisateur dans un groupe à ressources partagées. Des priorités sont préétablies pour des utilisateurs du même groupe à ressources partagées et stockées chez les utilisateurs. Le procédé comprend les étapes suivantes: lorsqu'un utilisateur qui a transmis une requête d'accès de liaison montante reçoit l'information transmise par le côté réseau indiquant que la voie de liaison montante est occupée, l'utilisateur décide si la priorité préétablie de l'utilisateur est supérieure à celle d'un utilisateur occupant actuellement la voie de liaison montante selon l'information reçue de la priorité de l'utilisateur occupant actuellement la voie de liaison montante transmise par le côté réseau du système à ressources partagées, si tel est le cas, l'utilisateur transmet une nouvelle fois la requête d'accès de liaison montante, et autrement, l'utilisateur détermine que l'accès à la liaison montante pour cette période à échoué.
