Abstract

Les modes de réalisation de la présente invention concernent un procédé et un terminal de gestion de session. Le procédé comprend les étapes suivantes : un terminal reçoit un premier message, envoyé par une entité à fonction de gestion d'accès et de mobilité (AMF), ledit premier message contenant, ou non, des informations d'un réseau local de données (LADN)) ; d'après le premier message, le terminal détermine qu'un changement s'est produit dans l'état de disponibilité du LADN ; le terminal modifie ou libère la session PDU. Les modes de réalisation de la présente invention réduisent la perte de données provoquée par la modification d'un réseau ou la libération d'une session PDU lorsqu'un terminal est dans un état inactif, et réduisent également le gaspillage de signalisation provoqué par un dispositif de réseau qui recherche un terminal lorsque des données de liaison descendante sont arrivées pour la session PDU du LADN auquel l'accès a été établi.
