Abstract

L'invention concerne un procédé, une entité fonctionnelle et un système réseau d'annonce d'une information concernant des utilisateurs se rapportant au domaine de la technologie de communication en réseau. À cet effet, la première entité fonctionnelle du réseau, où l'utilisateur se trouve couramment, obtient l'information concernant l'utilisateur. Cette première entité fonctionnelle détermine que le réseau où se trouve l'utilisateur est couramment le réseau visité d'après l'information concernant l'utilisateur. La première entité du réseau visité annonce l'information concernant l'utilisateur ou l'information concernant l'index, obtenue au moyen de l'information concernant l'utilisateur, à la première entité fonctionnelle du réseau domestique. Ainsi, le réseau domestique peut obtenir à l'information concernant l'utilisateur après que celui-ci passe en itinérance sur le réseau visité.
