The 3rd party SCS/AS sends a PFD Management Request (SCS/AS Identifier, external Application Identifier(s) and one or more sets of PFDs and PFD operation for each Application Identifier, Allowed Delay) message to the SCEF. The external Application Identifier(s) should be provided by an 3rd party SCS/AS that is known at the SCEF, so that the 3rd party SCS/AS and the MNO has an SLA in place. PFD operation indicates that the PFD is to be created, updated or removed in the operator's network. The Allowed Delay is an optional parameter. If the Allowed Delay is included, it indicates that the list of PFDs in this request should be provisioned to all the PCEF/TDFs known in the PFDF within the time interval indicated by the Allowed Delay.
Based on operator policies, if the 3rd party SCS/AS is not authorized to perform this request (e.g. if the SLA does not allow it due to the Allowed Delay is too short or other reasons), the SCEF performs step 6 and provides a Cause value appropriately indicating the error. Otherwise, the SCEF translates each external Application Identifier to the corresponding Application Identifier known at the PFDF.
