PURPOSE: A base station relay device using a beacon signal is provided to prevent that call disconnection is generated when a user moves from a 2.5G(Generation) system to a 2G system by outputting the beacon signal to the 2G system without passing a time corrector. CONSTITUTION: A beacon transceiver(100) generates a beacon signal to be used in a 2.5G system and a 2G system, and transmits and receives the beacon signal. A 2:1 divider(110) receives the beacon signal transmitted from the beacon transceiver(100), and divides the received beacon signal into the first and second beacon signals. A 2.5 relay processing device including a transmission signal combiner(120) and the first coupler(130) processes the first beacon signal divided by the 2:1 divider(110), and transmits the processed first beacon signal to a repeater. A 2G transmission processing device including a time corrector(140), the second coupler(150), and an LNA(Low Noise Amplifier)(160) processes the second beacon signal divided by the 2:1 divider(110), and transmits the processed second beacon signal to the 2G system.
