Abstract

La présente invention se rapporte à un procédé d'accès à un réseau, à un dispositif sur le côté réseau, et à un terminal. Le procédé selon l'invention consiste à recevoir une demande d'accès envoyée par un terminal, la demande d'accès contenant des informations d'indication qui indiquent si le terminal doit exécuter une transmission de données, ou non. Le procédé consiste d'autre part à déterminer, sur la base de la demande d'accès, s'il faut, ou non, allouer au terminal une ressource pour la transmission de données. Selon le procédé d'accès à un réseau, le dispositif sur le côté réseau, et le terminal de la présente invention, le message d'indication qui est utilisé pour indiquer si le terminal doit exécuter une transmission de données, ou non, est ajouté à la demande d'accès qui est envoyée par le terminal. De cette manière, le dispositif sur le côté réseau sait, à l'avance, s'il faut, ou non, allouer au terminal la ressource correspondante en vue de la transmission des données. D'autre part, comme le dispositif sur le côté réseau ne doit pas allouer de ressource à un terminal qui n'exécute pas une transmission de données, les ressources peuvent être économisées et le fonctionnement de services normaux peut être garanti.
