Patent ID: 8744342

Claim:
A method, implemented on a communication system, for identifying at least one terminal for which signals transferred between the at least one terminal and a base station of a wireless cellular telecommunication network have to be relayed by a relay device, the base station providing a random access channel enabling a terminal to notify to the base station the presence of the terminal by transferring a random access signal to the base station, the method comprising: transferring, by the relay device, a random access signal to the base station over the random access channel to notify the base station of the presence of the relay device, wherein the relay device is initially considered by the base station to be a new terminal in an area managed by the base station after receiving the random access signal; informing, by the relay device, the base station, after a response to the transferred random access signal is received, that the relay device is a relay that is configured to relay signals between the base station and at least one terminal, for authentication as the relay that is configured to relay signals between the base station and at least one terminal by a core network device; relaying, by the relay device, signals between at least one terminal and the base station.
