Hi, Ed and All:

In fact, I have the same idea like Ed when I explained yesterday that "home" administrative domain does not mean much unless home/visiting/target/visited GK/zone/network address (network point of attachment) information is there.

I guess that, like AT&T, Motorola has also contributions in supporting this concept.

I also sent email yesterday in response to Steve's email explaining the benefits. I also sent email to Jaakko explaining the things again in response.

I hope that these terms will be accepted and will be shown as Paul Guram explained in his mail by the editor.

Best regards, Radhika R. Roy AT&T

Hi All,

Administrative Domain I think is a Service provider's system. The word HOME should be left out because the Administrative Domain can apply anywhere. Therefore, one could say the "Administrative Domain" of the Serving (network or zone or GK), or the "Administrative Domain" of the Visited (network or zone or GK), or the "Administrative Domain" of the Transit (network or zone or GK), etc,. The Administrative Domain has no functions it can apply for fixed or mobile networks, nor does it need any protocol to support it.

On the other Hand!!!

As Paul pointed out the VLF,HLF and AuF are boxes with specific functions. In this case we can define the Home functions, Authorization functions Visited functions for each box. We can also have Home or Visited GK boxes with specific functions.

From Paul's meeting notes:

"The editor, will also consider to add some text to explain the boxes VLF,HLF and AuF, if these are also included in the new version of Annex H."

Hi Radhika & Laurent,

See my comments embedded...

...

The contributions and explanations have been provided why "Home" is needed in the same context of "Home" domain.

The Home Administrative Domain came about because it seemed a good idea

to

...

bind the subscription of a User to some administrative entity (such as

an

...

operator). At the same time we have defined the HLF as the only place in which location information about the user can always be found (albeit clearer definitions about this information are still needed). Thus the domain containing the HLF of the user was in effect defined as the Home Administrative Domain of the user.

...

If we do not accept the "home" for GK, zone and home network address, we have serious problems to accept the word "home" in any place of mobility whether it is "home" Adm domain.

I do not follow your reasoning above at all. Concidering a home GK or

zone,

...

I can understand that they may be needed if the service execution is

done in

...

the "home" of the user, i.e. all calls for a user would be controlled by

the

...

same GK, namely the home GK of the user. For service execution in the Visited Administrative Domain, I do not see any reason, why the concept

of a

...

home GK would be needed. Furthermore, if a concept is not definitely

needed,

...

I will not want to define it. I also feel we need to examine and define

the

...

"service execution in the home environment" or "virtual home

environment"

...

model better, so that everyone understands, what it is all about. As for the need for a home Network Point of Attachment, I am waiting for your contribution that clarifies, why we would need it.

...

I have very a serious objection with your idea that the word home should not be used. If it is so, let us NOT use "home" anywhere in the document.

The point is that so far, if I understand Laurent correctly, neither he

or I

...

have accepted the concepts of home GK or home Network Point of

Attachment.

...

Those are the terms that we would not like to see in the picture.

...

It is an OPTION to use "home". If anyone does NOT like it, they may NOT use it. Time and again, it has been shown why it is needed.

It will be very difficult to make any meaningful progress unless we are in consistent in defining term terms.

I like to see contributions explaining why "Home" should NOT be used.

I do not want to see contributions telling what terms SHOULD NOT be

defined,

...

I want to see contributions telling why some terms SHOULD be defined. So

far

...

I haven't seen such contributions on home NPoA and I'm still not sure

about

...

the home GK either.
