Abstract

Des modes de réalisation de la présente invention concernent un procédé et un appareil permettant de transmettre des informations d'établissement de liaison. Le procédé consiste à : acquérir, dans une couche PDCP d'un terminal, des informations d'établissement de liaison d'un service dans une période de silence ; selon une première table prédéterminée de correspondance de services, délivrer un message de notification de la couche PDCP du terminal à une couche MAC du terminal, le message de notification comportant des informations binaires d'un bitmap correspondant au service dans la période de silence ; et dans la couche MAC du terminal, envoyer, selon une adresse IP correspondant au service dans la période de silence, une signalisation de commande à un côté réseau d'accès radio (RAN), la signalisation de commande comportant les informations binaires du bitmap correspondant au service dans la période de silence, de sorte que le côté RAN reconstruise les informations d'établissement de liaison selon les informations binaires du bitmap correspondant au service dans la période de silence. Grâce aux modes de réalisation de la présente invention, une couche L2 maintient la connexion entre le service dans la période de silence et un terminal de destination sans ajouter un en-tête de protocole aux informations d'établissement de liaison, économisant de cette façon les ressources d'interface radio.
