Title: RE: COPS for UMTS

Bert,

 

You are right, nothing is final in 3GPP until the document is officially published.

But the current version of the document was approved in the main plenary meeting

and COPS is accepted with no dissidents as the "chosen" protocol.

 

Again, as for the details of the Go interface (based on COPS), I can't say much because it is still work in progress

and nothing is defined yet.

 

But I think the general agreement is that COPS-PR may be used for pre-provisioning of general policies

and something else is needed on a per flow basis for admission control.

 

Hope this 
clarifies,

Louis-Nicolas Hamer

I have seen that document. From that, it is not clear to me if

- Your are gonna do just COPS, which I think means no PIB

- You are also gonna do COPS-PR, which I think means a PIB

 

There is talk about using both RSVP and Diffserv for end-to-end QoS

so when I see Diffserv, then I suspect COPS-PR, but that is not clear.

 

Also... I thought that there was no final decision yet that COPS was

going to be the interface... the doc has not yet been approved, has it?

Sorry for not understanding the details of the process in 3GPP.
