Abstract

La présente invention porte sur un procédé et un appareil de commutation de personnalité. Le procédé consiste à : recevoir un message de requête de mise à jour de routage envoyé par un terminal, le message de requête véhiculant une première intensité de tonalité pilote d'une première branche courante et une seconde intensité de tonalité pilote d'une seconde branche, la première branche étant une branche courante utilisée par le terminal, et la seconde branche étant une branche dont l'ajout est demandé par le terminal ; déterminer qu'un système correspondant à la première branche est un premier système de réseau conformément à la première intensité de tonalité pilote ; déterminer qu'un système correspondant à la seconde branche est un second système de réseau conformément à la seconde intensité de tonalité pilote ; et si le premier système de réseau est différent du second système de réseau et la seconde branche satisfait une condition de déclenchement de commutation, commuter le terminal d'une personnalité correspondant au premier système de réseau à une personnalité correspondant au second système de réseau. Selon la présente invention, une commutation de personnalités correspondantes est exécutée selon si la branche à ajouter satisfait ou non une condition de déclenchement de commutation.
