Actually this case was thought already in the early stages of GPRS standardization. The idea could be also that the GGSN would be connected to a company intranet (directly), and the intranet would like to authenticate the user instead of the subscription to the mobile network, which is done by SIM authentication. Actually, it is possible to authenticate the user with PPP even without using the PDP Type PPP. In this case, there is a PPP connection between e.g. the laptop and the mobile phone, but PPP does not go across the air interface. The needed information for performing the authentication is transferred in the PDP Context Activation messages in the protocol configuration options to the GGSN. Then a protocol can be used to give the credentials to the network authenticated to, e.g. Radius. I cannot remember from the top of my head in which document this is, but I can look it up. However, I would not see this as an issue to our document but to 3GPP. 3GPP has to see itself if they are compliant with individual regulatory requirements. I would not think this as a task of the IPv6 WG. => this is a typical example of how some 3GPP people don't want to understand that most of us just like to use the 3GPP stuff in order to transport the traffic only... But I am not afraid, regulation bodies will explain again the meaning of the word "open" and will get what we'd like one day (:-).
I think I am somehow missing your point in this later extraction of your mail. As you say these options are available in the standards. => exactly.
