PURPOSE: A three-way relay service method for the emergency communication of a ship, a three-way relay processing method, a three-way relay system, and a terminal system are provided so that an arbitrary merchant ship/fishing boat/leisure boat rapidly communicates with an unknown ship in case of emergency. CONSTITUTION: A three-way relay system consists of an SSB(Single Side Band) transceiver(20), a VHF transceiver(21), a phone patch(24), a three-way relay interface(22), and a three-way relay control unit(23). The SSB transceiver(20) executes interconnection with a fishing boat. The VHF transceiver(21) executes interconnection with a merchant ship. The phone patch(24), connected to a mobile network, makes a mobile telephone(24-1) in an arbitrary ship connected. The three-way relay interface(22), organically connected to the SSB transceiver(20), the VHF transceiver(21), and the phone patch(24), relays and interfaces two among three ways, SSB, VHF, and a mobile telephone. The three-way relay control unit(23), organically connected to the SSB transceiver(20), the VHF transceiver(21), the phone patch(24), and the three-way relay interface(22), detects source information and determines two among three ways for relay.
