The invention discloses a random access method, a relay system includes a relay node RN judgment random access has been triggered; if random access is triggered, the use of non RN backhaul subframe for random access. In the invention, if random access in the state of base station of RN is triggered, then the RN can carry out random access sub frame part or all of the non use of resources of the backhaul link, random access subframe RN can use the Uu interface, the method can carry out the random access delay decreased as the base station work RN and improve the user experience.
