Hello,
I support the WG adoption of the draft (as a co-author and also from a tier-1 MNO). BR, -Tianji ==== FYI: Here I want to share one more case from 3GPP that would potentially benefit from the ANUP-like work in the future. The FS_5GSAT_Ph3 is a Phase-3 Satellite SID (i.e. project) of the 3GPP SA2 Release 19. Thanks to the flexible yet complicated 5GC, the SID has one architectural assumption to limit the working scope of the transport links (i.e., so-called inter-satellite link or ISL) in order to handle the challenges with both gNB and 5GC on-board satellite. When both gNB and 5GC are onboard satellite(s), it implies the criticalness of the effective communication between them. The connectivity between both could take place on either a satellite or multi-satellites with ISL in between. While this is a very challenging issue, the FS_5GSAT_Ph3 has put the assumption in that the connectivity as provided by ISL (and Feeder link) is a transport-layer problem and 3GPP will not touch it. Further, this SID/project also studies the UE-Satellite-UE communication between 2 or more UEs under the coverage of the same or different satellites. Evidently, the current gNB+5GC architecture does face challenges given the ever-dynamic changing of the underlay (satellite-based) constellation network. Fortunately, ANUP-like work could better serve the purpose (from both the control-plane and the user-plane perspectives). In summary, 3GPP does have projects that face challenges and might be ultimately & optimally addressed by IETF; 3GPP puts off addressing the issue thanks to the lack of (IETF) tools; Later (e.g., the 3GPP Rel-20 for 6G in about 12 months), 3GPP will for sure revisit the problem. By that moment, if the ANUP-like work has matured sufficiently, then it would be a potentially promising option for 3GPP’s consideration. Thus, the ANUP-like work is indeed a viable architecture for some hot demands right now and for the future.
