Abstract
La présente invention concerne des systèmes, des appareils et des procédés destinés à une procédure de transfert dans des réseaux hétérogènes. La présente invention porte en particulier sur un transfert intermédiaire (IHO). Certains aspects de l'invention portent sur un procédé exécuté au niveau d'une station de base de service d'un réseau de communications sans fil, la station de base de service desservant un équipement utilisateur (UE). Le procédé comprend la réception d'un indicateur de qualité de signal descendant (DL) en provenance de l'UE ; et la détermination, à partir de l'indicateur de qualité de signal, de la satisfaction ou non d'une condition pour un état de transfert intermédiaire (IHO). Si la condition pour l'état de transfert intermédiaire est satisfaite, la station de base de service peut initier l'état de transfert intermédiaire.
