Munster were humbled 18-9 at Thomond Park on Saturday by the Heineken Cup holders and Ryan admits it's a good learning curve ahead of their quarter-final tie against the Ravenhill outfit.
Ryan missed that clash after failing to recover from a bang on the shoulder but coach Tony McGahan is expected to welcome the 28-year-old back into the fold.
And Ryan believes that home advantage can prove the difference in this tie and a possible semi-final against either Edinburgh or Toulouse.
"To get a home quarter-final for the fans of Munster is brilliant," said Ryan. "It's going to be a massive task for us but hopefully we'll be up for the challenge.
"Ulster have had a good run of games and a massive victory over Aironi last week and we'll have to match them up front.
"Tom Court, Rory Best, Stephen Ferris, Chris Henry they're all internationals, we're in for a battle but hopefully we can come out on the right side and to do that we have to focus on ourselves.
"It's a massive game for us, when we started here against Northampton it was touch and go whether we'd actually come out of the group so it's a great achievement for us.
"Leinster are the team to beat in Europe, we were quite disappointed with the way the result went from our point of view last weekend, but we learnt a lot from that game.
"The intensity was there, but it was just a case of being sharper in a few areas and that's what we have been trying to do this week."
