Abstract

L'invention concerne un procédé permettant à un terminal d'accéder à une passerelle, ledit procédé comportant les étapes suivantes: une station de base (BS) transmet un message de diffusion à un terminal, ce message indiquant l'état de réseau de la BS (101); la BS acquiert les données de capacité du terminal (102); la BS sélectionne une passerelle pour le terminal selon les données de capacité du terminal et l'état de réseau de celui-ci (103). Les formes de réalisation de l'invention concernent aussi un dispositif permettant au terminal d'accéder à une passerelle, le procédé et le dispositif décrits dans les modes et formes de réalisation de l'invention permettant au terminal d'accéder à une passerelle, parmi de multiples passerelles.
