The subscription service costs $49.99 (£34.99) and grants users access to new content two weeks before it is made available to the public.
The game's 'Close Quarters' expansion, for example, is available to download for members today.
It also offers a stat-tracking feature and adds bonus items, weapons, vehicles and dog tags.
Users who sign up for the service will also receive the 'Back To Karkland' expansion for free.
It confirms earlier reports that the service would launch on the same day as EA's E3 press conference.
Details of Battlefield 3's upcoming expansions were also revealed. A future add-on will introduce motorbikes as an in-game vehicle.
