How is Tony Stark getting its suit to pick him up while he is in a battle?

Right now you have seen on the Movies on almost all Iron Man shit that basically the Tony Stark himself when he is being threatened by his enemies....There are all types of suits deployed in the movies. Now they are being programmed with his intellegent programmed AI System that is Holographic  displayed inside its brain and so when he picks up his phone and says "JARVIS" He responds with a male voice(YES,SIR COMING NOW!). He goes to the place where Tony finds a method to get up with distract him while he is running then he is actually going out to the hidden place and suits up himself and then so afterwards he goes into the battle.
