PURPOSE: A call/alarm system using a Bluetooth and a method therefor are provided to perform functions for calling a vehicle driver, preventing a vehicle burglar, starting a vehicle by a mobile terminal, and transmitting fingerprint data by wireless by performing an intercommunication between a Bluetooth module installed in the vehicle and a Bluetooth module installed in the mobile terminal. CONSTITUTION: If an analog signal is sensed in a vibration sensor(190) by an external vibration(impact), a vibration sensing device(180) receives the analog signal, operates a Bluetooth network, and transmits a call signal to a vehicle driver located in a long distance. If fingerprint data are inputted through an image sensor(170), a fingerprint recognizing device(160) compares the inputted fingerprint data with previously registered user fingerprint data and transmits a vehicle starting control signal and an alarm control signal. A DSP(Digital Signal Processor)(200) transmits a vehicle driver call control signal and a vehicle starting control signal according to the output signals of the vibration sensing device(180) and the fingerprint recognizing device(160), and controls the transmission and receipt of an RF(Radio Frequency) signal and data between a Bluetooth module of a vehicle and a mobile terminal(140). A vehicle starting device and alarm lamp control device(150) controls the vehicle stating or an alarm lamp of the vehicle according the control signal transmitted from the DSP(200), and controls a remote starting of the vehicle by the signal received from the mobile terminal(140). A Bluetooth chip(110) interworks with the DSP(200), transmits and receives wireless data, controls and outputs the wireless data, and processes the wireless data. An RF transmitting/receiving module(120) performs a wireless communication of the wireless data generated in the Bluetooth chip(110) within a uniform range, and transmits and receives the wireless data with the mobile terminal(140) through an RF input/output module(130).
