The invention discloses a mobile relay and an X2 interface proxy enhancing and processing method and overcomes the defect that currently under some circumstances, X2proxy may not be able to act between MR or HeNB and the like and adjacent base stations. The X2 interface proxy enhancing method includes: triggering the X2proxy to redirect from a first node to a second node or triggering to build an X2 interface between a third node and the second node; using the second node as the X2proxy of the third node and the adjacent base stations of the third node. By the method, interface proxy functions between nodes are enhanced.
