Vehicle information providing terminal, portable terminal, and operating method thereof

A callable terminal including a microphone and positioned in a vehicle, the terminal comprising:

• a wireless communication unit communicating through a short range communication module with a first mobile terminal providing a vehicle interface to a vehicle information providing terminal of the vehicle;
• a terminal information providing unit providing terminal information to the first mobile terminal when a request for retrieving the callable terminal is received from the first mobile terminal;
• an output unit outputting a remote call request message when a remote call request signal is received from the first terminal through the wireless communication unit;
• and
• a user input unit receiving whether the remote call request message is accepted,
• wherein the wireless communication unit receives a voice signal transmitted from the first mobile terminal and transmits a voice signal input through the microphone to the first mobile terminal when the remote call request is accepted, and
• wherein a wireless communication unit of the first mobile terminal comprises a short range communication module and a mobile communication module,
• wherein a call voice relay unit of the first mobile terminal relays a voice signal of the remote call between the callable terminal and the base station,
• wherein the call voice relay unit of the first mobile terminal transmits through the short range communication module a voice signal received from the base station through the mobile communication module and transmits a voice signal received through the short range communication module from the callable terminal to the base station through the mobile communication module, while the remote call is being provided by the callable mobile terminal's accepting the remote call.

A vehicle information providing terminal comprising:

• an interface unit connected with a first mobile terminal providing a vehicle interface;
• an output unit receiving and outputting the vehicle interface provided to the interface unit and providing a selection list through the vehicle interface when a call signal is received by the first mobile terminal;
• and
• a user input unit receiving a selection input for selecting a callable second mobile terminal from the selection list,
• wherein the interface unit transfers the selection input to the first mobile terminal receiving the call signal for a remote call between the first mobile terminal receiving the call signal and the second mobile terminal, and
• wherein the first mobile terminal further comprises:
• a wireless communication unit comprises a short range communication module and a mobile communication module and receives a call signal transmitted from a base station through the mobile communication module, and
• a call voice relay unit relays a voice signal of a remote call between the second mobile terminal, and
• wherein the call voice relay unit transmits through the short range communication module a voice signal received from the base station through the mobile communication module and transmits a voice signal received through the short range communication module from the second mobile terminal to the base station through the mobile communication module, while the remote call is being provided by the second mobile terminal's accepting the remote call.
