VERFAHREN ZUR VERARBEITUNG DER NEUAUTORISATION AUF DER BASIS DER ABRECHNUNG DES PAKETDATENFLUSSES

摘要

The present invention discloses a method for handling re-authorization in packet data flow based charging. The method includes: TPF monitoring re-authorization triggers; and requesting re-authorization of the credit in OCS when a re-authorization trigger is detected. In accordance with the method provided by the present invention, TPF pre-configuring re-authorization triggers, or OCS provides TPF with re-authorization triggers, so that TPF is able to acquire accurately the re-authorization trigger to be monitored; TPF monitors the occurrence of the re-authorization triggers and requests OCS to re-authorize the credit when a re-authorization trigger occurs, OCS re-calculates the credit and returns to TPF the recalculated credit. In this way, as there are more approaches for providing re-authorization triggers, the re-authorization process in packet data flow based charging can be implemented more definitely.
