Le procédé selon l'invention comprend les étapes suivantes : un dispositif de service de réseau personnel convergent (CPNS, Converged Personal Network Service) détecte une tentative d'accès de la part d'un dispositif non CPNS et le dispositif CPNS initie alors le mode proxy; le mode proxy signifie que le dispositif non CPNS est autorisé à accéder au réseau via le dispositif CPNS; dans le mode proxy, le dispositif CPNS transfère les données interactives entre le dispositif non CPNS et le réseau. La solution technique de la présente invention permet de résoudre le problème lié au fait que le dispositif non CPNS ne peut pas accéder au réseau via le dispositif proxy. De cette manière, le réseau CPNS est étendu et les possibilités, pour les dispositifs CPNS et les dispositifs non CPNS, d'utiliser des services au sein du réseau sont augmentées.
