PURPOSE: A TRS(Trunked Radio System) mobile relay base station system is provided to improve user convenience by enabling a user to separate a TSC(TETRA Site Controller) from a base radio. CONSTITUTION: A first network interface unit(130) provides a standard clock to a base radio. The first network interface unit provides an interface which connects to an external communication network. A system control unit(150) wirelessly connects to the external communication network. The system control unit controls the base radio, an RF(Radio Frequency) distribution unit, and the first network interface unit. A power distribution unit(140) provides power to the base radio, the RF distribution unit, the first network interface unit, and the system control unit.
