Abstract

La présente invention se rapporte aux technologies de communication. L'invention concerne une méthode et un dispositif pour le rapport et l'obtention d'informations de redirection. Après la réception d'une commande de réacheminement, un UE enregistre des informations associées à un évènement de réacheminement et envoie le rapport des informations enregistrées associées à l'évènement de réacheminement à un côté réseau, de façon qu'un dispositif côté réseau puisse obtenir des informations de redirection de l'UE et qu'une station de base initialisant le transfert ou le réacheminement puisse effectuer des opérations d'optimisation ultérieures selon les informations de redirection.
