Abstract
A telematics control system includes: a telematics unit in a vehicle including a modem unit that transmits vehicle information via an external mobile communication channel; and a telematics center transmitting and receiving channel change information of the modem unit based on a message indicating a channel state of a paging mode or a quick paging mode of a channel selected according to communication environment information acquired from the telematics unit.
Claims11
A telematics control system comprising:
- a telematics unit in a vehicle including a modem unit that transmits vehicle information via an external mobile communication channel;
- and
- a telematics center transmitting and receiving channel change information of the modem unit based on a message indicating a channel state of a paging mode or a quick paging mode of a channel selected according to communication environment information acquired from the telematics unit, wherein
- the telematics center monitors information about the telematics unit and changes a channel of the modem unit, when service exchange with the telematics unit fails a predetermined amount of times or more, and
- the telematics unit receives channel change information from the telematics center, changes the channel of the modem unit to a channel belonging to a predetermined range, and transmits the changed channel information to the telematics center.

A telematics control method comprising:
- transmitting, by a telematics unit in a vehicle, electric field information of a modem unit included in the telematics unit, vehicle power state information, vehicle information and mobile communication channel information to a telematics center when the vehicle is powered on;
- determining whether a service is exchanged between the telematics unit and the telematics center in real-time;
- transmitting a channel change command of the modem unit when an electric field level of the modem unit is less than a predetermined level in response to determining that the service is not exchanged in real-time;
- changing the channel of the modem unit based on the transmitted channel change command such that the telematics unit and the telematics center are connected in real-time;
- transmitting the changed channel information of the modem unit to the telematics center;
- when service exchange with the telematics unit fails a predetermined amount of times or more, monitoring, by the telematics center, information about the telematics unit and changing, by the telematics center, a channel of the modem unit;
- receiving, by the telematics unit, channel change information from the telematics center;
- changing, by the telematics unit, the channel of the modem unit to a channel belonging to a predetermined range;
- and
- transmitting, by the telematics unit, the changed channel information to the telematics center.

A telematics control method comprising:
- determining a communication channel state between a telematics unit in a vehicle and a telematics center via a modem unit in real-time when the vehicle is powered off;
- changing the modem unit to a sleep mode in order to reduce vehicle battery power consumption;
- transmitting a remote control message from the telematics center to the telematics unit;
- transmitting a channel change message of the modem unit to a mobile terminal of a driver when a telematics service execution message is not received;
- changing a channel of the modem unit;
- transmitting state information of the modem unit to the telematics center;
- when service exchange with the telematics unit fails a predetermined amount of times or more, monitoring, by the telematics center, information about the telematics unit and changing, by the telematics center, a channel of the modem unit;
- receiving, by the telematics unit, channel change information from the telematics center;
- changing, by the telematics unit, the channel of the modem unit to a channel belonging to a predetermined range;
- and
- transmitting, by the telematics unit, the changed channel information to the telematics center.
