Abstract

Cette invention concerne un procédé d'enregistrement de service par accès IP comprenant les opérations suivantes: (a)le terminal utilisateur actuel envoie la demande d'enregistrement IP au port IP; (b) le port IP qui a reçu la demande d'enregistrement de service du terminal utilisateur actuel stocke l'information d'enregistrement de l'utilisateur, puis adresse une réponse au terminal utilisateur actuel. Ce procédé permet à l'unité de stockage d'informations utilisateur de connaître l'information d'adresse fournie par le port IP et enregistrée par le terminal actuel, de transmettre cette information à d'autres entités pour que le terminal utilisateur effectue l'enregistrement service par le port IP, et de transmettre à l'unité de stockage d'informations utilisateur l'information du port IP à temps pour que la totalité du flux de service puisse être assurée.
