Abstract

La présente demande porte, selon les modes de réalisation, sur un procédé d'indication d'état de service, sur une station de base et sur un terminal. Le procédé comprend les étapes suivantes : une station de base configure une relation de liaison entre un support radio de données (DRB) de service et un support DRB de rapport, le support DRB de service étant utilisé pour transmettre des données d'un service, le support DRB de rapport étant utilisé pour transmettre des informations d'état de service du service, et les informations d'état de service étant utilisées pour indiquer l'état de service actuel du service ; la station de base envoie à un terminal des informations de liaison utilisées pour indiquer la relation de liaison ; et la station de base reçoit les informations d'état de service envoyées par le terminal sur la base du support DRB de rapport et ajuste une politique de transmission du support DRB de service. Le problème selon lequel un réseau ne peut pas obtenir les informations d'état de service à temps, provoquant un retard de transmission lorsqu'un paquet de données est transmis, de telle sorte qu'une exigence de service ne puisse pas être satisfaite ou qu'une ressource de transmission soit gaspillée, peut être résolu en utilisant les modes de réalisation de la présente demande.
