Abstract

La présente invention concerne, dans des modes de réalisation, un procédé permettant à un terminal d'accès de sélectionner une fréquence résidente. Le procédé comprend : l'envoi d'un message système ; lorsque la version du protocole acceptée par le terminal d'accès est une version qui prend en charge une liste de canaux étendue au cours de la négociation de configuration, évaluation pour savoir si le terminal d'accès doit être résident dans une fréquence de porteuse dans la liste des canaux étendue, si besoin est, puis configuration de l'attribut de négociation de configuration du terminal d'accès pour être l'attribut de la version qui accepte la liste de canaux étendue, sinon, configuration de l'attribut de négociation de configuration du terminal d'accès pour qu'il s'agisse de l'attribut de la version qui ne prend pas en charge la liste de canaux étendue. Les modes de réalisation de l'invention concernent aussi un équipement côté réseau et un équipement côté terminal permettant à un terminal d'accès de sélectionner une fréquence de porteuse résidente. Le procédé et l'équipement garantissent que la fréquence de porteuse résidente sélectionnée par l'AT selon l'attribut de version introduit au cours de la négociation de configuration et la règle de la fréquence de porteuse résidente de l'AT déployée dans le réseau peut rester cohérente, de manière à s'assurer que le schéma de la mise en réseau mixte pour deux versions différentes du protocole soit possible.
