Signalling flow for TS 23.502 General Register - old AMF to (V-)PCF: AMF-Initiated Policy Association Termination


Step 20, verbatim
[Conditional] old AMF to (V-)PCF: AMF-Initiated Policy Association Termination.
If the old AMF previously initiated a UE Policy Association to the PCF, and the old AMF did not transfer the PCF ID(s) to the new AMF (e.g. new AMF is in different PLMN), the old AMF performs an AMF-initiated UE Policy Association Termination procedure, as defined in clause 4.16.13.1, to delete the association with the PCF. In addition, if the old AMF transferred the PCF ID(s) in the UE context but the new AMF informed in step 10 that the UE Policy Association information in the UE context will not be used then the old AMF performs an AMF-initiated UE Policy Association Termination procedure, as defined in clause 4.16.13.1, to delete the association with the PCF.
