Hello Janos

There is a 3rd reference that I expect you want to replace too.

The new text would be:

   In addition, several enhancements have been done on system architecture level
   which are reflected in System architecture for the 5G System (5GS)
   [TS23501]. These enhancements include multiple features in
   support of Time-Sensitive Communications (TSC) by Release 16 and Release 17.
   Further improvements will be considered in the 3GPP Release 18 time frame,
   e.g., support for DetNet [TR2370046].

Also I expanded TSCTSF on first use as:
Time Sensitive Communication and Time Synchronization Function (TSCTSF)

This is save in github as

Unless objections are raised, this will be part of the next publication.

Subject: [Raw] updating the RAW technologies draft

Hi,

As we discussed at IETF 115, the LS https://datatracker.ietf.org/liaison/1800/ explains that 3GPP SA2 has concluded their DetNet Study Item.

I think it would be good to bring the RAW technologies draft up-to-date on that.

This could be done by replacing

   [SP211633] 3GPP, "New SID: Extensions to the TSC Framework to support
              DetNet", 3GPP SP-211633, December 2021,
              <https://www.3gpp.org/ftp/tsg_sa/TSG_SA/
              TSGS_94E_Electronic_2021_12/Docs/SP-211633.zip>.

with

[TR2370046] 3GPP, "Study on 5GS DetNet interworking", 3GPP TR23.700-46, August 2022, < https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=3994>.

and updating the corresponding text in 6.4.5, e.g.:

OLD:

   IETF Deterministic Networking (DetNet) is the technology to support
   time-sensitive communications at the IP layer. 3GPP Release 18
   includes a study [SP211633] on whether and how to enable 3GPP support
   for DetNet such that a mapping is provided between DetNet and 5G.
   The support for DetNet is considered to be added via the TSC
   framework introduced for Release 17.  The study includes what
   information needs to be exposed by the 5G System and the translation
   of DetNet flow specification to 5G QoS parameters.  Note that TSN is
   the primary subnetwork technology for DetNet.  Thus, the DetNet over
   TSN work, e.g., [RFC9023], can be leveraged via the TSN support built
   in 5G.  As the standards are ready for such an approach, it is out of
   scope for the 3GPP Release 18 study item [SP211633].

NEW:

   IETF Deterministic Networking (DetNet) is the technology to support
   time-sensitive communications at the IP layer. 3GPP Release 18
   includes a study [TR2370046] on interworking between 5G and DetNet.
   Along the TSC framework introduced for Release 17, the 5GS acts as
   a DetNet node for the support of DetNet, see Figure 7.1-1 in
   [TR2370046].  The study provides details on how the 5GS is exposed
   by the TSCTSF to the DetNet controller as a router on a per UPF
   granularity (similarly to the per UPF Virtual TSN Bridge granularity
   shown in Figure 11). In particular, it is listed what parameters are
   provided by the TSCTSF to the DetNet controller. The study also
   includes how the TSCTSF maps DetNet flow parameters to 5G QoS
   parameters. Note that TSN is the primary subnetwork technology for
   DetNet. Thus, the DetNet over TSN work, e.g., [RFC9023], can be
  leveraged via the TSN support built in 5G. As the standards are ready
   for such an approach, it is out of scope for the 3GPP Release 18
   study item [TR2370046].
