Abstract

A communication system included in a telematics unit is provided. A GPIO communication port connects a plurality of communication modules included in the telematics unit, and thus enables each of the communication modules to transmit/receive data depending on the data transmission/reception state of the other communication module. Accordingly, provided are a telematics communication system and method that prevents a data transmission/reception speed from being reduced due to frequency interference between the plurality of communication modules.

Claims

1. A telematics communication system, comprising:

a plurality of communication modules transmitting and receiving data over different frequency bands; and

a communication port connecting the communication modules, the communication port being controlled depending on a data transmission and reception state of a first communication module of the connected communication modules, and the communication port supplying information on the data transmission and reception state of the first communication module to a second communication module of the communication modules,

wherein the second communication module checks the data transmission and reception state of the first communication module through the communication port, and when the first communication module is transmitting and receiving data, the second communication module does not transmit data.

2. The telematics communication system of claim 1, wherein,

when the first communication module is receiving data, the second communication module does not transmit data, and

when the first communication module does not receive data, the second communication module transmits data.

3. The telematics communication system of claim 1, wherein,

when the first communication module is receiving data, the communication port maintains a high state, and

when the first communication module does not receive data, the communication port maintains a low state.

4. The telematics communication system of claim 3, wherein,

when the communication port maintains the high state, the second communication module does not transmit data, and

when the communication port maintains the low state, the second communication module transmits data.

5. The telematics communication system of claim 4, wherein the first communication module is a WiBro communication module, and the second communication module is a Wi-Fi communication module.

6. The telematics communication system of claim 4, wherein the first communication module is a Wi-Fi communication module, and the second communication module is a WiBro communication module.

7. The telematics communication system of claim 1, wherein the communication port is a GPIO communication port.

8. A telematics communication method, comprising:

checking whether a first communication module transmits and receives data;

setting a communication port connected to the first communication module to a high state when the first communication module is receiving data and, when the first communication module does not receive data, setting the communication port to a low state;

checking, by a second communication module, a state of the communication port; and

transmitting data depending on the state of the communication port, wherein the second communication module connected to the communication port does not transmit data when the communication port is in the high state and, when the communication port is in the low state, the second communication module transmits data.
