Abstract

La présente invention porte sur un procédé et un système permettant à une passerelle d'accès local d'obtenir des informations d'appel d'un terminal. Le procédé comprend les opérations suivantes : une unité de gestion de mobilité envoie les informations d'appel d'un terminal utilisées pour un appel local à un élément de réseau côté sans fil; l'élément de réseau côté sans fil envoie les informations d'appel reçues du terminal à une passerelle d'accès local. La présente invention peut assurer que la passerelle d'accès local peut mettre en œuvre une optimisation d'appel lorsque le terminal est en veille et reçoit les données de liaison descendante de connexion locale.
