Abstract

L'invention concerne un procédé de changement d'état. Selon ledit procédé : après qu'un équipement utilisateur (UE) est passé d'un état de canal de radiomessagerie de zone d'enregistrement de réseau d'accès radio terrestre de système universel de télécommunications mobiles (URA_PCH) à un état de canal d'accès aller de cellule (CELL_FACH), une station de base reçoit des premières données de liaison montante envoyées par cet UE, les premières données de liaison montante contenant un identificateur de niveau non cellulaire de l'UE ; et des secondes données de liaison montante sont envoyées à un contrôleur de réseau radio (RNC), les secondes données de liaison montante contenant l'identificateur de niveau non cellulaire de l'UE, de sorte que le RNC détermine l'UE conformément à son identificateur de niveau non cellulaire. Au moyen du procédé de migration de données proposé par les modes de réalisation de la présente invention, après qu'un UE est passé d'un état URA_PCH à un état CELL_FACH, un RNC détermine l'UE dont proviennent les données et réalise une réception et une émission de données normales avec l'UE.
