Abstract

La présente invention concerne, dans certains modes de réalisation, un procédé de contrôle d'accès, un dispositif, et un support de stockage informatique. Le procédé peut comprendre les étapes suivantes : un équipement utilisateur (UE) et un dispositif côté réseau établissent une relation de mappage entre un identifiant de tranche court (SSI) et des informations d'assistance de sélection de tranche de réseau (NSSAI), le SSI et les NSSAI ayant la relation de mappage indiquant une même tranche de réseau, et la longueur du SSI est plus courte que celle des NSSAI ; l'UE transporte, sur la base de la relation de mappage, le SSI d'une tranche de réseau cible dans une signalisation de liaison montante ; l'UE envoie la signalisation de liaison montante transportant le SSI de la tranche de réseau cible, la signalisation de liaison montante étant utilisée pour que le dispositif côté réseau effectue une commande d'accès sur la tranche de réseau cible sur la base du SSI. La présente invention non seulement réduit la consommation de ressources de signalisation et évite le gaspillage de ressources de signalisation entre un UE et un côté réseau, mais elle réduit également le retard pour la commande d'accès sur une tranche de réseau.
