The connection to Game Center is not "lost" immediately, I am unsure of the actual timeout period, and would not count on it being any particular period if it is not specified in the docs somewhere. You can always test it for a particular release/version using two connected players.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
