Abstract
A data relay method includes receiving a relay request from a BS, and when the relay request is accepted, relaying data between the BS and at least one external terminal, or the data relay method includes determining relaying between a first terminal among a plurality of terminals, and other remaining terminals excluding the first terminal among the plurality of terminals, and relaying data between the first terminal and the other remaining terminals.
Claims17
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.
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.
