Hi John, thank you for the update. As you mentioned, I reviewed section 3.3 in terms of both the prior to PDU session establishment, and during PDU session establishment.
In section 3.3 para 2, the draft says below: > 3GPP user plane nodes (gNB, UPF) are provisioned with GTP transport > interface information parameters in [TS.28.541-3GPP] for an S-NSSAI. > But I couldn't find exact IOC or attribute defined in TS28.541 to bind GTP transport interface info parameters for an S-NSSAI. Can you please indicate where the IOC and/or the attribute defined in TS28.541? Also in section 3.3 para 3, the draft says below: > During PDU session setup, the 5G control plane configures parameters > to setup the user plane for the PDU session across F1-U, N3 and N9 > interfaces. They include the S-NSSAI and corresponding EP_Transport > information which contains the IP address interface of the GTP-U > destination and the connectionPointID with attachment circuit > information. The 3GPP user plane node can now associate the > provisioned slice and EP_transport to that signaled for the PDU > session. > I suppose that the above text implies N2, or N4 interface procedures since it describes PDU session establishment. But I couldn't find neither EP_Transport nor connectionPointID parameters in both the N2 (TS38.413) and N4 (TS29.244). So can you please indicate where those parameters are included in the N2 and N4? In addition, the Fig.3 in the draft depicts EP_Transport info model which includes some attributes of the connectionPointIDType, and the connectionPointID. But I couldn't find those attributes in EP_Transport IOC in TS28.541. So can you please indicate where those attributes are defined in EP_Transport IOC?
