How to manage communication among controllers in Meteor?

I’m new to Meteor framework and found one issue with communication among different controllers.
I’m using AngularJS on client side and I know that AngularJS provides methods such as: $broadcase, $emit, $on etc. to handle communication among peer controllers.
Just wondering, what’s the right way in Meteor to handle communication among controllers? (e.g., I would like to call an event handler or function belonging to another controller, what should I do?)
