Abstract

L'invention concerne des systèmes, des appareils et des procédés destinés à une procédure de transfert dans des réseaux hétérogènes. En particulier, un transfert intermédiaire (IHO) est introduit. Certains aspects de l'invention concernent un procédé mis en uvre au niveau d'une première station de base d'un réseau de communications sans fil. Une indication, selon laquelle un équipement d'utilisateur (UE) reçoit un signal de couverture provenant d'une deuxième station de base, peut être reçue. Un paquet de données destiné à l'UE peut être envoyé à la deuxième station de base. Une liaison de communications avec l'UE peut être maintenue après l'envoi du paquet de données à la deuxième station de base.
