Dear Hesham, This what is in current 3GPP specifications, is not necessarily the "right thing".
Recommendation shall include the right network topology and IPv6 mechanism, not deal with system, which is only "half" right. Andrew D.

There are people that want to roll out systems with IPv6 support today, R&D will no doubt improve things, but in this draft we need to deal with the current specs.
