Hi Ralph, Thanks for your comments! Please see inline.
Minor issues: > I had some difficulty unraveling the relationship among the text in section > 3.3.2, 3.3.3, 4 and RFC 7315. Section 3.3.2 specifies the > inclusion of the NPLI option in the P-Access-Network-Info header field. > Section 4 does not include text about the NPLI option in the > updates to RFC 7315, and I can't find any reference to the NPLI option in RFC > 7315.

Sections 3.3.2 and 3.3.3 describe the 3GPP use-cases which justify the changes to RFC 7315. Section 4 defines those changes. Section 4 then defines the changes to RFC 7315, in order to support those use-cases. RFC 7315 (Annex A) does talk about the possibility for network provided location information, and the ABNF supports it, but the details of the network provided location information (and the other types of location information) are defined in the 3GPP specification. > Section 3.3.3 specifies the inclusion of the IOI option in the > P-Charging-Vector header field. In this case, I am not sure if this > specification represents a change to existing text in RFC 7315 or new > behavior. Section 3.3.3 (and 3.3.2) does not update RFC 7315. Section 3.3.3 only provides the use-case/justification for the update. The update to RFC 7315 is specified in section 4. > I would be happy to hear that I am completely confused; otherwise, I suggest > some text be added to clarify that sections 3.3.2 and 3.3.3 also specify some > behaviors in addition to explaining the text in section 4. Does my clarification above clarify? Nits/editorial comments: > In section 3.2, it would reduce potential confusion to consistently name the > header field referenced in each bullet; e.g.: > > OLD: > > o P-Called-Party-ID: Delete statement that the header field can > appear in SIP responses.

Add statement that > the P-Called-Party-ID header field can appear in the SIP REFER method. I’ll fix as suggested. >Section 3.3.1: > >OLD: > >This following sections describe, for individual P- header fields, > the 3GPP use-cases that are base for the updates. > >NEW: > > The following sections describe, for individual P- header fields, > the 3GPP use-cases that are the basis for the updates. I’ll fix as suggested. > Section 3.3.2: uniformly capitalize "Network Provided Location Information". I’ll fix as suggested. > Section 3.3.2: 3GPP TS 23.228 needs a citation of the referenced document. I’ll add the reference. Thanks! Regards, Christer
