Apparatus and method for implementing an autonomous GPS function and an emergency signal transmitting function is described. In one embodiment, the apparatus includes a switching unit for changing a connection path of a GPS signal received through an antenna when a request to transmit an emergency signal is made. The first converting unit receives the GPS signal and calculates position information based on the GPS signal. In another embodiment, the switching unit changes a connection path of the position information calculated by a GPS signal processing unit when the request to transmit the emergency signal is made. A mobile communications modem receives the position information and transmits same to a base station. The mobile communication modem also controls the changing of the connection path of the switching unit when the request to transmit the emergency signal is made. Accordingly, load on a control unit can be decreased.

A system for reducing power consumption by a telematic terminal comprises a NAD (Network Access Device) processor having a processor core, a CIU (Communication Interface Unit), and a telematic terminal controller operatively coupled between the CIU and the NAD processor on board a vehicle. The controller and the NAD processor core are configured to be turned off and driven, respectively, in a power saving mode when the vehicle ignition is turned off. The power saving mode changes into a signal reception standby state after a pre-set period of time. The NAD processor operates normally during the signal reception standby state.
