Abstract

L'invention concerne un procédé de téléavertissement et un centre de commutation mobile, le procédé comprenant les étapes suivantes : après avoir reçu une requête d'appel de service, un SC ou un VLR téléavertit un terminal dans un réseau du domaine à commutation de circuits ; déterminer, durant le processus de téléavertissement, si le terminal a été transféré vers un réseau d'évolution d'architecture système (SAE) ; si tel est le cas, un MSC ou un VLR téléavertit le terminal au moyen d'une interface SGs. Les modes de réalisation selon la présente invention permettent à un MSC/VLR d'ajouter une interface SGs durant un processus de téléavertissement du domaine à commutation de circuits, résolvant ainsi le problème d'une défaillance du téléavertissement causée par un UE se déplaçant dans différents réseaux, et augmentant le taux de succès d'un UE dans un réseau hybride du domaine à commutation de circuits et SAE.
