How it Works
Revalidation time is a string of the format "date-time" as defined in OpenAPI specification. The SMF, on receiving the revalidation time in "revalidationTime" attribute and RE_TIMEOUT trigger in "policyCtrlReqTriggers" attribute, starts a timer for the difference duration (revalidationTime – currentTime – 5 seconds buffer). Once the timer expires, the SMF initiates the PCF interaction to request PCC rules.
