Abstract

La présente invention concerne un procédé, un système et un appareil destinés à supporter une connectivité de données organisées dans une zone visitée qui accède à des scénarios itinérants. Ledit procédé comprend les étapes suivantes : selon les documents de connectivité de données organisées d'un réseau visité, la V-PCRF (fonction de politique visitée et règles de facturation) autorise la connectivité de données organisées fournie par l'AF (fonction d'application), qui est visitée par un utilisateur itinérant, se localisant au niveau du réseau visité ou ayant une relation d'abonnement avec le réseau visité, à réaliser une visite dudit utilisateur itinérant à ladite connectivité de données organisées.
