MVC falls under architectural pattern and is primarily concerned with UI and interaction logic separation. The other layers of the 3 tier will still be applicable.
The most common MVC frameworks usually follow a Front Controller pattern. i.e. rather than request getting landed to a specific page, the request is routed to a common front controller, whose sole responsibility is to invoke the specific requested controller
based on information passed in the querystring or as part of the request.
Ideally the controller should be as thin as possible and its sole responsibility should be to infer the request and call appropriate business or data access service. There shouldn't be any business specific logic in the controller.
My recommendation is to look at the ASP.NET MVC implementation for more information as this is built on the industry adopted best practices...
