Abstract

La présente invention concerne un procédé et un appareil de configuration de trajet de transmission. Elle relève du domaine technique des communications et sert à répondre à des exigences spécifiques de différents types de services. Le procédé comprend les étapes au cours desquelles : un dispositif de réseau d'accès reçoit une demande de traitement de session envoyée par un dispositif de réseau central ; le dispositif de réseau d'accès génère des informations de configuration de trajet de transmission en fonction de la demande de traitement de session, les informations de configuration de trajet de transmission servant à indiquer un trajet de transmission permettant de transmettre un paquet de données cible entre un terminal et le dispositif de réseau d'accès ou entre deux terminaux ; et le dispositif de réseau d'accès envoie les informations de configuration de trajet de transmission au terminal. La solution technique d'après la présente invention est applicable à un processus de configuration de trajets de transmission.
