Abstract

L'invention concerne un procédé de communication, un terminal, une station de base, et un équipement de gestion de la mobilité. Le procédé de communication comprend les étapes suivantes : un terminal transmet à une station de base un message d'indication de capacité indicatif du terminal supportant un service vocal dans un premier réseau et un service de données dans un second réseau; le terminal reçoit de la station de base un message d'indication d'établissement de service vocal ordonnant au terminal d'effectuer un service vocal dans le premier réseau, et maintenir un état de service courant dans le second réseau; le terminal maintient l'état de service courant dans le second réseau et exécute le service vocal dans le premier réseau, sur la base du message d'indication d'établissement de service vocal. L'invention permet d'améliorer la qualité d'un service vocal tout en garantissant l'efficacité de transmission d'un service de données.
