Abstract

La présente demande, qui relève du domaine technique des communications, concerne un procédé et un appareil de communication. Selon le procédé, un premier dispositif génère des informations d'indication utilisées pour indiquer la catégorie d'un flux de données et envoie les informations d'indication à un second dispositif, le flux de données étant une session PDU ou un flux de QoS dans la session PDU. Au moyen du procédé, le second dispositif peut être informé de la catégorie du flux de données de sorte que le second dispositif peut réaliser un traitement spécifique sur le flux de données selon la catégorie du flux de données, ce qui évite le problème selon lequel une transmission de données ne peut pas satisfaire des exigences de communication ou selon lequel des ressources de communication sont gaspillées.
