Apparatus and method for processing signal of telematics terminal
First Claim
1. An apparatus for processing a signal of a telematics terminal, comprising:
- a global positioning system (GPS) functioning unit for providing an autonomous GPS function by calculating position information based on the signal;
a radio frequency (RF) functioning unit for calculating position information based on the signal and for transmitting the calculated position information to a base station when a request to transmit an emergency signal is received; and
a switching unit for selectively providing the signal received through the antenna to the GPS functioning unit during normal operation or to the RF functioning unit when the request to transmit the emergency signal is received.

Abstract
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.
