Abstract

La présente invention concerne un procédé d'hébergement en réseau comprenant: la génération par le côté réseau du message d'indication qui sert à indiquer au terminal utilisateur son hébergement en réseau; la transmission par le côté réseau du message d'indication au terminal utilisateur, pour indiquer au terminal utilisateur de sélectionner le réseau correspondant pour son hébergement selon le message d'indication. Par conséquent, selon un mode de réalisation, l'invention concerne un système de réseau comportant : un dispositif côté réseau permettant la génération du message d'indication qui indique au terminal utilisateur son hébergement en réseau, la transmission du message d'indication au terminal utilisateur, indiquant au terminal utilisateur de sélectionner le réseau correspondant pour son hébergement selon le message d'indication ; le terminal d'utilisateur permettant la réception du message d'indication qui est transmis par le dispositif côté réseau, la sélection du réseau correspondant pour son hébergement selon le message d'indication. Le mode de réalisation selon l'invention concerne également un dispositif côté réseau et un terminal utilisateur correspondant. Le schéma du mode de réalisation selon l'invention peut optimiser l'hébergement de l'équipement utilisateur dans le réseau, et assurer une meilleure utilisation des ressources du réseau.
