RE: [Sipping-tispan] Requirements -02g

["Hans Erik van Elburg (RY/ETM)" <[e-mail]>]

Hi,

Since the calling parties category is not suitable nor ment for the case in which override of ACR is needed. And it was  said that we would come back to this requirement once it is time to discuss Calling Party's Category.

There is currently no TISPAN service that requires calling parties category, but it has been added for interworking reasons (basic call) and to allow services to (as a network option) act on this.  Follows that there is no relation with ACR whatsoever.

We propose to unhide the requirement that allows certain calls to bypass the ACR service. I think the last formulation of that requirement read:

	REQ-ACR-3: The originating network shall be able to indicate to the 
	terminating network that the caller of an anonymous communication is 
	authorized to bypass the ACR service at the callee's network.

Which was somewhere around
http://www1.ietf.org/mail-archive/web/sipping-tispan/current/msg00070.html
in the mailing list.

Best Regards,

/Hans Erik

Subject: [Sipping-tispan] Requirements -02g


Hi:

I have this working copy of the requirements, version -02g:

http://people.nokia.net/~miguel/drafts/pre/draft-jesske-sipping-tispan-requirements-02g.txt
http://people.nokia.net/~miguel/drafts/pre/draft-jesske-sipping-tispan-requirements-02g.html

And a diff version with respect -02f:

http://people.nokia.net/~miguel/drafts/pre/draft-jesske-sipping-tispan-requirements-02f-to-g.html

The changes in this version are:
- Grouping of the CCBS/CCNR requirements for better understing
- A few clarifications to the CDIV requirements
- Addition of the Calling Party Category requirements.

Now, I have a few questions.

- The Calling Party Category requirements do not constitute a service by 
  itself. In my opinion, they should be General requirements listed a 
REQ-GEN-4 and REQ-GEN-5. Does anyone oppose to move them to the General 
section?

- We had a pending action point to revisit the ACR requirements once we 
have drafted the Calling Party Category requirements. Now we have 
achieved this state, and my opinion is that we don't need to add any 
extra wording to ACR, since the Calling Party Category requirements 
cover the use case we have been discussing (police anonymously call a 
user with ACR activated).

Last, but not least, WE ARE ALMOST DONE with the requirements. So please 
take a look at this draft and comment on any pending issue. I would like 
to solve issues as soon as possible and submit the draft for publication.

Regards,

         Miguel
