Fandyllic is correct. The term you should be using is "interwiki link".

In the case of Wikipedia, the URL of the mobile and non-mobile pages are the same except for the "m". For example:

http://en.wikipedia.com/wiki/Wikia

http://en.m.wikipedia.com/wiki/Wikia

You then create the interwiki link, wp:Wikia, which will bring you to the non-mobile page. However, if Wikipedia detects that you are using a mobile device, it will automatically redirect you to the mobile page. This feature is common amongst sites which have both mobile and non-mobile layouts. In fact, Wikia does the same. Although there is no required relation between the mobile and non-mobile URLs, it is typically easier for everyone if the distinction in made in the domain (similar to hosting various languages). To this end, most websites simply tack on the "m".
