Let me tip my hand a little.
I can't reveal which GPS Locate system I was involved with but we used a variety of ways to trigger a GPS Locate (google that if you don't know the lingo) and for the answer we used IP over cellular packets.
Yes there were 2 web servers in the system so I'm unsure exactly what you want to know. Well I can guess you want the deep technical how this Samsung system works but as you know most companies consider such to be the secret sauce and won't tell all.
If you feel that's wrong, don't buy the product.
Have your ever heard of "Plan B" for Android?
