DSCP to PPI Control Information

NOTE 1: The CP function may request the UP function to drop the packets currently buffered for the PFCP session when using extended buffering of downlink data packets, buffering is performed in the UP function and the DL Data Buffer Expiration Time is handled by the CP function. In this case, when the DL Data Buffer Expiration Time expires, the CP function shall send a PFCP Session Modification Request including the DROBU flag (to drop the downlink data packets currently buffered in the UP function) and updating the Apply Action within the FARs of this PFCP session to request the UP function to start buffering the downlink data packets with notifying the arrival of subsequent downlink data packets. See clause 5.9.3 of 3GPP TS 23.214 [2].

NOTE 2: When changing the CP F-SEID of an established PFCP Session, the CP function shall be able to handle any incoming PFCP Session related messages sent by the UP function with the previous CP F-SEID for a duration at least longer than twice the PFCP retransmission timer (N1xT1).

NOTE 3: The QAURR (Query All URRs) flag in the PFCPSMReq-Flags IE and the Query URR IE are exclusive from each other in a PFCP Session Modification Request.

NOTE 4: If the ATSSS resources have already been allocated to the PFCP session previously, e.g. during the PFCP session establishment, the UPF shall not allocate new values for such resources (e.g. UE Link-Specific IP Address).

NOTE 5: S-NSSAI for the PDU session may be updated after PDU session establishment, i.e. during EPS to 5GS handover procedure, the initial AMF may use configured S-NSSAI for interworking to create the PDU session in 5GS. For home routed PDU session, if the S-NSSAI in serving PLMN (mapped from S-NSSAI in HPLMN) is different from the configured S-NSSAI for interworking and V-SMF reselection is not needed, the AMF will update V-SMF with S-NSSAI in serving PLMN for the PDU session, as specified in clause 4.11.1.3.3 of 3GPP TS 23.502 [29]. The S-NSSAI may also be updated by SMF+PGW-C during EPS to 5GS handover in non-roaming or roaming-with-LBO case. The S-NSSAI may be used by the UP function for performance measurement.

NOTE 6: When transferring port and user plane node management information between the TSN AF or the TSCTSF and the NW-TT, since the NW-TT may support multiple ports, there may be several instances of the TSC Management Information IEs containing a Port Management Information Container together with a NW-TT Port Number, and only one instance of the TSC Management Information IE containing a User Plane Node Management Information Container that may also contain a Port Management Information Container together with a NW-TT Port Number.
