Method and system for providing vehicle security service

A vehicle security service provision method in a vehicle telematics unit linked with a vehicle gateway through a communication network in a vehicle, the method comprising steps of:

• receiving an external device connection-informing message from the vehicle gateway;
• transferring the external device connection-informing message to a designated user terminal through a wireless network;
• receiving an external appliance connection acceptance message from the user terminal through the wireless network;
• and
• transferring the received external device connection acceptance message to the vehicle gateway.

A vehicle gateway for providing a vehicle security service in connection with a vehicle telematics unit, the vehicle gateway comprising:

• a unit for checking whether or not an external device has been connected;
• a unit for transmitting an external device connection-informing message to the vehicle telematics unit through communication in a vehicle upon determination that the external device has been connected;
• a unit for receiving an external device connection acceptance message from the vehicle telematics unit;
• and
• a unit for processing a diagnosis request message received from the external device in response to the received external device connection acceptance message.

A vehicle telematics unit for providing a vehicle security service in connection with a vehicle gateway through a communication network in a vehicle, the vehicle telematics comprising:

• a unit for receiving an external device connection-informing message from the vehicle gateway;
• a unit for transferring the external device connection-informing message to a designated user terminal through a wireless network;
• a unit for receiving an external appliance connection acceptance message from the user terminal through the wireless network;
• and
• a unit for transferring the received external device connection acceptance message to the vehicle gateway.

A system for providing a vehicle security service in connection with a wireless network, the system comprising:

• a vehicle gateway for sensing whether or not an external device has been connected via an on-board diagnosis (OBD) connector and creating an external device connection-informing message;
• and
• a vehicle telematics unit for transferring the external device connection-informing message to a designated user terminal through the wireless network upon receiving the external device connection-informing message from the vehicle gateway, receiving, from the user terminal, a message representing whether or not connection of the external device has been accepted, and transferring the received message to the vehicle gateway,
• wherein the vehicle gateway determines whether or not a diagnosis request message received via the OBD connector should be processed, based on the message representing whether or not connection of the external device has been accepted.
