Abstract

La présente demande, qui relève du domaine technique des communications, concerne un procédé et un appareil de configuration de paramètres, un dispositif, et un support de stockage. Le procédé comprend : l'envoi, par un dispositif de terminal distant, d'informations de configuration de paramètres à un dispositif de terminal de relais, les informations de configuration de paramètres comprenant un premier filtre de paquet de données et des premiers paramètres de description de données de trafic correspondant au premier filtre de paquet de données. Les solutions techniques fournies par des modes de réalisation de la présente demande résolvent le problème technique selon lequel le dispositif de terminal de relais ne peut pas obtenir, d'une couche supérieure de celui-ci, des paramètres de description de données de trafic d'un service. Puisque le dispositif de terminal de relais peut obtenir des paramètres de description de données de trafic d'un service au moyen des informations de configuration de paramètres, le dispositif de terminal de relais peut en outre configurer correctement des paramètres de session PDU sur la base des paramètres de description de données de trafic du service de façon à déterminer une session PDU sur la base des paramètres de session PDU, ce qui permet au dispositif de terminal distant de transmettre des données de trafic à un réseau.
