Abstract

La présente invention concerne, dans des modes de réalisation, un procédé et un dispositif servant à vérifier des ressources de bande passante, destinés à être utilisés pour la vérification de ressources de bande passante avant qu'un élément de réseau du plan de commande n'établisse des porteuses dédiées, le tout concernant le domaine des communications. Le procédé comprend les étapes suivantes : un élément de réseau du plan de commande envoie un message de demande de bande passante à des éléments de réseau du plan utilisateur afin de demander une ressource de bande passante correspondant à chacun des n objets statistiques ayant différentes granularités correspondant à des porteuses dédiées à établir et détermine ensuite, en fonction des messages de résultat de demande de bande passante, s'il faut établir des porteuses dédiées ; ou l'élément de réseau du plan de commande envoie aux éléments de réseau du plan utilisateur un message de création de porteuse dédiée qui comprend des identifiants de n objets statistiques ayant différentes granularités correspondant à des porteuses dédiées à établir et les ressources de bande passante devant être occupées par les porteuses dédiées, de manière à déterminer, en fonction des messages de réponse de porteuses dédiées, s'il faut établir des porteuses dédiées. Grâce aux modes de réalisation de la présente invention, le problème suivant peut être résolu : une passerelle du plan de commande (CGW) n'est pas apte à décider s'il faut lancer la création de porteuses dédiées selon un état d'occupation de ressources de bande passante d'une porteuse dédiée sur une passerelle distribuée (DGW).
