Hello,

I don't object to the adoption of this work, but the focus of the draft should be changed to address details of realizing "ANUP".
That would be necessary for a useful RFC down the line, and not what 3GPP should (or should not) do.


The current draft focus is on advocating why 3GPP should do something:

(i.e., "If the ideas in this document are deemed reasonable, feasible and desired among these  parties, they can then be brought to 3GPP for further discussions.".)

This goal is perhaps better accomplished with a discussion paper in 3GPP SA2/SA1, rather than an IETF RFC that says what is better to do in 3GPP.



On the other hand, more information on realizing ANUP in "wireline"/IP and mobility aspects should be provided.

For example, aspects on addressing, mobility, performance, measurement, manageability of entities and services, scalability, etc.

I would note that 3GPP only defines AN and UPF functions, while this draft can add value by describing how to realize an N x M AN and UPF instances behaving as a single manageable "ANUP" entity.

(and assuming/based on already defined 3GPP CP session and mobility functionality)

Regards,
John
