Various exemplary embodiments relate to a method performed by a policy and charging rules node (PCRN) device for implementing a PCC procedure with SDF inputs, the method including: receiving a PCC request with a SDF input; determining if the PCC request is from a user equipment (UE); mapping flow direction information from the SDF input request into a unified flow-direction record stored in the PCRN; generating PCC, ADC, and/or QoS rules based upon the unified flow-direction record; determining if flow direction is defined on an output interface; mapping the unified flow-direction record into a flow-information AVP associated with the generated PCC, ADC, and/or QoS rules.
