[Teas] Responses for LS on "Realization of Network Slices for 5G Networks Using Current IP/MPLS Technologies"

[Vishnu Pavan Beeram <[e-mail]>]

WG,



We sent a liaison statement [1] in June to multiple 3GPP groups seeking
feedback on our WG draft that discusses “Realization of Network Slices for
5G Networks Using Current IP/MPLS Technologies” [2].

We have received replies from 3GPP-TSGSA-SA2 [3], 3GPP-TSG-SA-WG5 [4] and
O3GPPTSGRAN3 [5]. We request the WG to review the feedback and chime in
with your thoughts/opinions.



The following is our (chairs’) interpretation of the feedback that was
received.



   - 3GPP-TSGSA-SA2:
      - Remove Appendices B.1 and B.2 and just have a reference to TS-23.501
      - No endorsement of the “Hand-off” options discussed in Section 4 and
      the QoS Mapping Realization Models in Section 5
         - This need not warrant any changes to Sections 4 and 5. We need
         to ensure that the language used in these two sections
doesn’t imply any
         endorsement by 3GPP.
      - 3GPP-TSG-SA-WG5:
      - Fix the reference to 3GPP TS 28.530
   - O3GPPTSGRAN3:
      - Inaccuracies exist in Appendix B.3. Suggest adding references to
      TS-38.300 and TS-38.401
         - In other words, this is a recommendation to remove Appendix B.3.



Based on the above, our recommendation is to remove Appendix B (including
the Transport Network specific sub-section) and add the suggested
references in the Introduction. The authors have published a new revision
(rev 10) with Appendix B removed. Please review the latest changes and let
us know if there are any comments/concerns.



Regards,

-Pavan and Oscar
