Lockring Wrench
You need a lockring tool. This is a good one.
The tool grabs the little notches in the raised ring closest to the camera. Unscrew that.
With the lockring off you should be able to remove the cup and the spindle, like someone else described.
My favorite lock-ring tool:

You can make a chain whip by drilling three holes in a strip of 1/8" thick strip of steel and tap the chain pins back through the holes:

You can add handles and shaping as above, but just filing or sanding off and sharp edges and wrapping it with some old bar tape or inner tube will work just fine. There was a good thread on chain whips a while back...
The one that /u/singlejeff linked to is definitely a lot better than Park Tool's old lockring wrench. This one is much better for those headset notched nuts: https://www.amazon.com/Hozan-Bicycle-Bottom-Bracket-Wrench/dp/B0017SE6ZY
