RE: on NAT-PT

[<juha.wiljakka@nokia.com>]

 Hello!

What comes to 3GPP specifications, Mobile IPv6 is *not* a mandatory part of 3GPP architecture in Release 99, Release 4 and Release 5. Mobility is handled by Layer 2 mechanisms: GPRS Tunneling Protocol (GTP) handles the global (macro) mobility and the UE can be attached to the same GGSN all the time. But it is possible to use MIPv6 starting from Release 99, i.e. nothing prevents you.

What comes to 3GPP Release 6 (that is currently being specified), Mobile IPv6 is discussed there. A good use case for Mobile IPv6 would be handling GPRS / WLAN mobility.

However, one thing that is needed is frozen MIPv6 specification (=RFC)... let's hope that we get it finalized soon!  :-)

Best Regards,
