Abstract

La présente invention concerne un procédé de réglage de largeur de bande. Le procédé consiste à : (101) recevoir, pour un service courant, des informations de type de service envoyées par un dispositif de passerelle ; et (102) régler la largeur de bande couramment utilisée par le service courant selon les informations de type de service afin d'assurer la qualité de service (QoS) du service courant, la largeur de bande couramment utilisée par le service courant étant la largeur de bande indiquée par un paramètre de largeur de bande configuré pour l'utilisateur courant selon un paramètre de largeur de bande obtenu de l'utilisateur courant. La présente invention permet de limiter la largeur de bande et d'assurer la QoS pour différents utilisateurs et différents services.
