Om jag förstått det rätt så betyder Native IP att hela systemet är byggt med "native" eller naturlig IP. Alltså data transformeras aldrig till ett annat format än IP. Det är alltså IP hela vägen för all sorts data.

The inherent complexity of retrofitting legacy circuit-switched systems adds reliability challenges, as well as complexity in design, implementation and operations. In addition, the expansion of such a system will be more difficult and require proprietary switches and equipment.
A native IP architecture has built-in autonomy and survivability, delivering a system that is reliable, highly available and doesn't have to involve additional cost or complexity."
Det är så att säja ett "rent" IP-system (bara IP i hela mobilen).
