Abstract

L'invention concerne un procédé et un système permettant le détachement d'un équipement utilisateur (UE), ledit procédé comprenant les étapes suivantes : l'UE adresse une demande de détachement à une fonction de commande d'attachement au réseau (NACF) ; la fonction NACF transfère une demande de suppression de la relation de mappage identificateur-localisation à une fonction de commande de mappage identificateur-localisation (ILMCF) à réception de la demande de détachement ; la fonction ILMCF supprime la relation de mappage identificateur-localisation sauvegardée de l'UE à réception de la demande de suppression de la relation de mappage identificateur-localisation. La solution permet la mise en œuvre fiable du détachement de l'UE lorsqu'il n'est pas nécessaire pour l'UE de maintenir l'attachement au réseau IPSPLIT
