If Push Notification is disabled and Push Messages are sent, when are they get recived?

In my Android App I have used UrbanAirship to receive Push Notification. My web application sends me the notifications, which works great.

Now if my Push is disabled in my Android apps Push Preference, I am not getting any push messages - which works as expected. Now I made my Push Enable, Quick Question - when will my app receives those notification sent by my web app when my App was in disable mode.

Thanks, Panache
