Section: F.6 5GS DetNet node configuration
Content: The DetNet controller triggers the procedure to provide Deterministic Networking specific parameters to 5GS. Figure F.6-1: Deterministic Networking specific parameter provisioning 1. The DetNet controller provides YANG data model configuration to the TSCTSF. The TSCTSF uses the identifier of the incoming and outgoing interfaces to determine the affected PDU Session(s) and flow direction, whether it is uplink or downlink as described in more detail in clause 5.28.5 of TS 23.501[ System architecture for the 5G System (5GS) ]  [2]. The TSCTSF also determines if the flow is UE to UE in which case two PDU Sessions will be affected for the flow and the TSCTSF breaks up the requirements to individual requirements for the PDU Sessions. 2. The TSCTSF uses the traffic requirements in the YANG configuration as described in clause 6.1.3.23b of TS 23.503[ Policy and charging control framework for the 5G System (5GS); Stage 2 ]  [20]. The TSCTSF also constructs the TSCAC for each flow description. 3. The TSCTSF provides the mapped parameters and the flow description to the PCF(s) on a per AF Session basis. 4. The PCF authorizes the request from TSCTSF. If the PCF determines that the requirements can't be authorized, it rejects the request. Once the PCF authorizes the request, the PCF updates the SMF with corresponding new PCC rule(s) with PCF initiated SM Policy Association Modification procedure as described in clause 4.16.5.2. The SMF applies the received PCC rules. This can induce creating a new QoS flow to the PDU session and triggers the resource allocation in the RAN. 5. PCF provides response to the TSCTSF. 6. The TSCTSF provides response to the DetNet controller.
