Abstract

La présente invention se rapporte au domaine technique des communications et, en particulier, à une technologie d'activation de fonction de délestage de données dans un système de communication mobile. Dans un procédé d'activation de fonction de délestage de données, un appareil de commande détermine, en fonction d'un niveau de service, un nœud cible parmi au moins deux nœuds connectés à un réseau d'application local, et active une fonction de délestage de données du nœud cible pour un terminal. Par la suite, le terminal peut obtenir un service dans lequel des flux de paquets IP de liaison montante sont délestés au moyen de la fonction de délestage de données. Le réseau d'application local est généralement commandé par un opérateur ou fourni par un prestataire de services (vérifié par l'opérateur), et une distance de transmission de service entre le réseau d'application local et le terminal peut être commandée par l'opérateur ou le prestataire de services. En conséquence, il est possible de fournir un service de faible retard de haute qualité au terminal par l'intermédiaire du réseau d'application local, de façon à satisfaire les demandes de services AR, VR, UHD et autres nécessitant un retard moins important.
