Abstract

La présente demande concerne un procédé de communication et un appareil associé. Le procédé comprend les étapes suivantes : un premier dispositif de réseau desservant un premier terminal envoie une première indication au premier terminal, la première indication étant utilisée pour indiquer un identifiant du premier terminal ; le premier terminal envoie la première indication au premier dispositif réseau au moyen d'une interface interne et le premier dispositif réseau envoie une demande d'établissement à un second dispositif réseau, la demande d'établissement comprenant la première indication ; et le premier dispositif réseau envoie au second dispositif réseau une réponse indiquant le succès de l'établissement. Dans ce mode de réalisation, il est possible d'établir une connexion de communication entre un dispositif réseau (c'est-à-dire le premier dispositif réseau) prévu conjointement pour le terminal et un dispositif réseau (c'est-à-dire le second dispositif réseau) desservant le terminal. En transférant la première indication, autrement dit quand le premier dispositif réseau envoie la première indication au premier terminal, le premier terminal envoie ensuite celle-ci au second dispositif réseau et le second dispositif réseau envoie ensuite celle-ci au premier dispositif réseau, la connexion de communication peut être établie entre le premier dispositif réseau et le second dispositif réseau.
