Abstract

Les éléments suivants sont rangés dans une mémoire (108): du logiciel pour exécuter une application prédéterminée; de l'information portant sur l'application active; une application de changement de mode de connexion permettant de changer le mode de connexion à un réseau; et une information d'activation automatique pour indiquer si l'application de changement de mode de connexion est ou n'est pas automatiquement activée pour chaque application prédéterminée. Quand une carte de radiocommunications est insérée pendant l'utilisation d'un réseau câblé, une logique de commande d'activation automatique (111) lit en mémoire (108) l'information d'activation automatique ainsi que l'information d'application active, puis décide s'il y a lieu ou non d'activer l'application de changement de mode de connexion. Un contrôleur (103) se conforme au résultat de cette décision pour activer l'application de changement de mode de connexion et commuter la connexion sur un réseau radio.
