1. A data relay method enabling a terminal to relay data between a base station (BS) and at least one external terminal located outside of a service area of the BS, the method comprising:
- receiving a relay request from the BS;
when the relay request is accepted, relaying data between the BS and the at least one external terminal;
requesting handover with respect to the relay request from the BS; and
handing over the relay role to a relay terminal newly selected by the BS.

14. A data relay method enabling a relay terminal to relay data between a plurality of terminals, the method comprising:
-
determining relaying between a first terminal among the plurality of terminals, and other remaining terminals excluding the first terminal among the plurality of terminals; relaying data between the first terminal and the other remaining terminals; after a new terminal establishes a direct link with the first terminal, receiving, by the first terminal, a handover instruction with respect to relay transmitted from the first terminal; and handing over the relay role to the new terminal. - View Dependent Claims (15, 16, 17)
