Abstract

L'invention concerne la technique de la communication sans fil. L'invention concerne un procédé, un système et un dispositif de libération de ressources dans l'interopérabilité mondiale pour un réseau d'accès micro-ondes permettant à l'authentificateur d'ancrage de libérer les ressources associées à temps lorsqu'une station mobile quitte le réseau. Le PC/LR d'ancrage gère les stations mobiles et s'il détecte qu'une station mobile quitte le réseau, il informe l'authentificateur d'ancrage à l'aide d'un message comportant un ou plusieurs identificateurs de la station mobile qui quitte le réseau, et l'authentificateur d'ancrage efface les informations sécurisées de la station mobile correspondante en fonction des identificateurs. L'invention permet de libérer des ressources du système à temps et augmenter l'efficacité d'utilisation des ressources du système par effacement des informations sécurisées. Lorsque le PC/LR d'ancrage informe l'authentificateur d'ancrage que la station mobile quitte le réseau, le PC/LR d'ancrage peut utiliser un nouveau message ajouté ou un message existant qui est développé.
