<p>A system and method for charging based on packet data flow makes the charging rule function (CRF) and the online charging system (OCS) together to constituent a logic function (CRF-OCS). The said CRF-OCS connects to the traffic plane function (TPF) via the interface including the function of Gx datum point and Gy datum point. So the event trigger can be made with the re-authorisation triggers together to implement. The event report mechanism of TPF is unified. The present invention describes a plurality of process of OCS configuration based on the CRF function implemented, and includes: the process of interacting provision charging rules and user credit between TPF and CRF-OCS, the interactive process of between CRF-OCS and TPF based on the charging trigger, the process of interacting relative information between CRF-OCS and AF, and the process of interacting user credit using situation between TPF and CRF-OCS. It makes the process clearer between TPF and OCS or between TPF and CRF.</p> |
