Abstract

Selon la présente invention, un procédé de gestion de ressources de support radio de terminal comprend les étapes, suivant lesquelles RRC du terminal initialise chaque type de tableaux de ressources de support avec les tableaux en série à traiter et les tableaux en série établis de chaque type de tableaux, le terminal établit la connexion de contrôle de ressources radio et, après réception du message de configuration de support provenant du côté réseau, RRC décode le message et vérifie la validité. Une fois la vérification accomplie avec succès, RRC stocke chaque paramètre du message dans le tableau en série de ressources de support correspondant à traiter en fonction du type et du mode de fonctionnement de IE dans le message, il envoie la demande de configuration à chacune des entités de support et transfère les paramètres associés, chaque entité traitant la demande de configuration et retournant la réponse à RRC. Si la configuration est réussie, RRC modifie les éléments du tableau en série de chaque tableau de ressources de support dans le tableau en série établi et transmet la réponse liée à la réussite au côté réseau dans la nouvelle configuration. Le procédé de cette invention permet également de réaliser le partage de ressources de support du terminal et le contrôle d'optimisation des ressources de support radio et il intègre les processus.
