Abstract: The present invention discloses a method for handling event triggers and re-authorization triggers in packet data flow based charging. The method comprises: TPF estimating whether the bearer event currently occurred matches an event trigger, if the bearer event matches an event trigger, TPF performing a charging rule request process, then TPF estimating whether needs to trigger a re-authorization process, if it does, performing a re-authorization process, otherwise, ending the current process; if the bearer event does not match any event trigger, just estimating whether needs to trigger a re-authorization process, if it does, 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 packet data flow based charging is improved.
