next and previous link in custom post type in the same taxonomy term

Question

I have a custom post type name->('portfolio'), with a taxonomy name ('portfolio_category'). what i want is to put next and previous link on its single page file which is single-portfolio.php. when i click either of the links it should redirect to the next or previous post in the same post type and in the same taxonomy term.

i used next_post_link() and previous_post_link() but it seems that it only works in single post but not in single custom post type..

please.. any idea guys.. any help will greatly appreciated..
