BF4 how do i invite a friend to a multiplayer lobby

[blacklight77]

At least in the ps3 u can join the server your friends are in the friends tab. In the ps4 ? Play alone even though i always have friends online. Sad.....

ghosts may not be as large as bat 4 but still at least you can succesfully lobby up before you join a game, unlike bat 4.
