Abstract

L'invention porte sur un procédé de transfert de système sans interface système, et sur un dispositif et un support de stockage, le procédé comprenant les étapes suivantes : un terminal dans un mode SR détermine qu'une condition pour un transfert de système est satisfaite, et dans un mode DR, lance un transfert vers un second côté réseau ; après que le second côté réseau a établi pour le terminal une seconde conversation de réseau qui correspond à une première conversation de réseau dans un premier réseau, et a achevé le transfert de la première conversation de réseau à la seconde conversation de réseau, le terminal libère la connexion avec le premier réseau et retourne au mode SR. Par application de la solution de la présente invention, des retards peuvent être réduits.
