Le procédé d'accès en liaison montante consiste à : régler des ressources de réservation et envoyer des informations de notification de ressource de réservation à au moins un terminal ; recevoir des signaux de réservation envoyés par au moins un terminal par l'intermédiaire des ressources de réservation séparément ; et envoyer un message d'attribution de ressource d'accès en liaison montante à l'au moins un terminal conformément aux signaux de réservation séparément, de manière que l'au moins un terminal effectue un accès en liaison montante au moyen de ressources d'accès en liaison montante correspondant au message d'attribution de ressource d'accès. Selon le procédé, le dispositif et le système d'accès en liaison montante des modes de réalisation de la présente invention, un dispositif de tête de réseau attribue les ressources de réservation en premier lieu et attribue ensuite les ressources d'accès en liaison montante au terminal seulement après avoir reçu les signaux de réservation envoyés par le terminal, ce qui permet de prévenir un gaspillage de ressource non nécessaire qui peut être causé par le fait que de nombreuses ressources d'accès en liaison montante sont toujours conservées pour une détection de liaison montante.
