Dear Benoit, Only one remark the correct group names are: 3GPP TSG CT WG4 or in short CT4 3GPP TSG SA WG5 or in short SA5

Lionel and I had a call. Based on that, Lionel, who is well aware of 3GPP process, reworked this liaison statement: To put the IAB LS tool and the tool will do the job for you (check with Charles) To GPP-TSGSA-SA5, GPP-TSGCT-CT4 From contact: Charles Eckel <ecke...@cisco.com><mailto:ecke...@cisco.com> To contact: Susanna Kooistra 3gppliai...@etsi.org<mailto:3gppliai...@etsi.org>, Peter Schmitt <peter.schm...@huawei.com><mailto:peter.schm...@huawei.com> Cc: Peter Schmitt, opsawg Response contact: opsawg chairs Purpose: for information Body: The IETF Operations and Management Area Working Group (OPSAWG) would like to kindly inform the 3GPP TSG SA5 WG and 3GPP TSG CT4 WG that the working group is currently working on the following Internet-Draft: “Export of GTP-U Information in IP Flow Information Export (IPFIX)” (https://datatracker.ietf.org/doc/draft-ietf-opsawg-ipfix-gtpu/). This document specifies IPFIX Information Elements (IEs) that can be used to export information contained in the GTP-U header such as Tunnel Endpoint Identifier (TEID), QoS Flow Identifier (QFI), and PDU Type from the PDU Session Container extension header. IETF OPSAWG aims to publish this Internet-Draft as Standards Track RFC in the upcoming months. IETF OPSAWG kindly ask 3GPP TSG SA5 WG and 3GPP TSG CT4 WG interested to review this document and provide comments if any. Note that the OPSAWG encourages the use of WG mailing list (https://www.ietf.org/mailman/listinfo/opsawg) as the most effective and expedient way of exchanging information, answering questions, and clarifying concerns. OPSAWG Chairs Joe Clarke & Benoît Claise Unless there is more feedback, we propose to send it beginning of next week. Many thanks Lionel. Regards, Benoit.

From the structure of the document it is not clear if you expect any kind of feedback it sounds like an information you want to provide. Means the groups receiving it will simply note it, possibly without any discussion. If you want to get feedback the document should be formatted as a document requesting feedback from the addresses groups. Means you need to ask for an action.

I agree with the points raised by Lionel. The LS should have a stated purpose of either "for information" or "for action". If for action, the action(s) and any deadline for such action should be specified. In this case, it seems the LS is intended to be for information. If OSPAWG is seeking answers to specific questions or confirmation that specific information is correct, those details should be stated here. Also, any LS to 3GPP needs to be formatted as a meeting contribution such that it can be treated at an upcoming meeting by the targeted 3GPP groups (e.g., SA5 and CT4). I can help with that.

From the LS, it is not so clear whether it is requested an informal feedback from 3GPP or if it is expected that this LS will trigger a specific work in 3GPP (e.g. adoption of IPFIX to export of GTP-U Information). For the latter, this LS will have to be supported by a 3GPP document submitted by a 3GPP member involved in the WG (likely SA5) to further discuss this aspect. These comments are just to ensure that OPSAWG will received a feedback from 3GPP. Otherwise, it is likely that this LS will just be simply “noted” by 3GPP.

Benoît and I, as chairs of opsawg, are drafting the attached liaison statement to send to 3GPP on the IPFIX/GTP-U work that is happening in opsawg. We’d like to get their additional review of that work. Since dmm is also engaged in GTP work, we wanted to send this LS here to get a review of the text and see if you would like to add anything and have the dmm chairs co-sign with Benoît and me. Thanks! Joe and Benoît
