Abstract

La présente invention concerne un procédé et un dispositif de traitement d'un signal vocal, et un support de stockage. Le procédé comprend les étapes suivantes : après qu'un équipement utilisateur commute d'un premier réseau à un second réseau, une entité de gestion de mobilité (MME) effectue une mise à jour d'emplacement d'un domaine à commutation de circuits; la MME rejette une demande d'établissement de support pour initier un service vocal.
