Method for Handling Event Triggers and Re-Authorization Triggers in Flow Based Charging

摘要

The present invention discloses a method for handling event triggers and re-authorization triggers in flow based charging. The method comprises: TPF determines whether the bearer event matches an event trigger, if the bearer event matches an event trigger, TPF requesting the charging rules from CRF, then TPF determines whether the bearer event matches a re-authorization trigger, if it matches, the TPF performing a re-authorization process, otherwise, ending the current process; if the bearer event does not match any event trigger, just determining whether the bearer event matches a re-authorization trigger, if it matches, the TPF performing a re-authorization process, otherwise ending the current process. In this way, only one interaction for re-authorization is needed between TPF and OCS, thus the re-authorization process is optimized when there is overlap between event triggers and re-authorization triggers, and the re-authorization process in flow based charging is improved.
