Abstract

L'invention concerne un procédé et un appareil d'indication pour un réseau de données local (LADN), destinés à être utilisés pour résoudre le problème, rencontré dans l'état de la technique, relatif au gaspillage de ressources de signalisation. Le procédé consiste à : obtenir des premières informations, les premières informations comprenant un premier nom de réseau de données (DNN) et une première indication pour indiquer que le premier DNN est un DNN correspondant à un LADN, ou les premières informations comprenant un premier DNN, le premier DNN comprenant une seconde indication pour indiquer que le premier DNN est un DNN correspondant à un LADN ; et déterminer que le premier DNN est un DNN correspondant à un LADN selon les premières informations obtenues de façon à déterminer s'il faut envoyer un message de demande d'établissement/de modification/d'activation de session PDU à un premier dispositif de réseau central, le DNN correspondant à une session PDU étant le premier DNN. Les informations de LADN comprennent le DNN du LADN disponible pour un terminal dans la zone d'enregistrement actuelle et des informations de zone de service correspondant au LADN.
