In Battlefield 3 there is a queue to join a server. You can jump this queue if you have a reserved slot! (VIP slot)
What happens if the server is full, but a player wants to join a server without a reserved slot?
The player joins a queue. Each player in the queue is shown their current position in the queue. Thus, they can choose whether they would prefer to wait or move to a different server. The server processes this queue as soon as a slot becomes available on the server. Then a player from the queue joins the server.

Players with VIP slots are at the front of the queue.
Players who have bought a Premium are next in line.
After that are the "normal" players.
