Abstract

A portable communication terminal transmits a request signal that requests voice data representing an email message, to a server apparatus when the portable communication terminal receives the email that has been sent to the portable communication terminal, and the portable communication terminal transmits the voice data received from the server apparatus, to an in-vehicle equipment. A server apparatus converts an email message that has been sent to a portable communication terminal, into voice data in response to a request signal received from the portable communication terminal, and the server apparatus returns the voice data to the portable communication terminal. The in-vehicle equipment detects a position of a portable communication terminal in a cabin, and the in-vehicle equipment outputs a voice message converted only from voice data representing an email message received by the portable communication terminal located in a specific position in the cabin, inside the cabin of the vehicle.

Claims

1. A data communication system, comprising:

an in-vehicle equipment for installation in a vehicle;

a portable communication terminal configured to communicate with the in-vehicle equipment; and

a server apparatus configured to communicate with the portable communication terminal, wherein

the portable communication terminal includes;

a request unit that transmits a request signal requesting voice data representing an email message, to the server apparatus when the portable communication terminal receives an email that has been sent to the portable communication terminal; and

a transmission unit that transmits the voice data received from the server apparatus, to the in-vehicle equipment,

the server apparatus includes;

a converter that converts the email message sent to the portable communication terminal, into the voice data in response to the request signal received from the portable communication terminal; and

a return unit that returns the voice data to the portable communication terminal, and

the in-vehicle equipment includes;

a voice output unit that outputs a voice message converted from the voice data received from the portable communication terminal, inside a cabin of the vehicle;

a detector that detects a position of the portable communication terminal in the cabin; and

a permission unit that permits outputting of the voice message converted only from the voice data representing the email message received by the portable communication terminal located in a specific position in the cabin.

2. The data communication system of claim 1, wherein the specific position is one of a plurality of predetermined areas inside the cabin of the vehicle.

3. The data communication system of claim 2, wherein a user sets one of the plurality of predetermined areas to be the specific position.

4. The data communication system of claim 1, wherein the specific position is a driver'"'"'s seat area of the vehicle.

5. An in-vehicle equipment for installation in a vehicle, comprising:

an obtaining unit that obtains voice data representing an email message received by a portable communication terminal located in a cabin of the vehicle;

a voice output unit that outputs a voice message converted from the voice data, inside the cabin of the vehicle;

a detector that detects a position of the portable communication terminal in the cabin of the vehicle; and

a permission unit that permits outputting of the voice message converted only from the voice data representing the email message received by the portable communication terminal located in a specific position in the cabin.

6. The in-vehicle equipment for installation in a vehicle according to claim 5, wherein the specific position is one of a plurality of predetermined areas inside the cabin of the vehicle.

7. The in-vehicle equipment for installation in a vehicle according to claim 6, wherein a user sets one of the plurality of predetermined areas to be the specific position.

8. The in-vehicle equipment for installation in a vehicle according to claim 5, wherein the specific position is a driver'"'"'s seat area of the vehicle.

9. A data communication method used amongst an in-vehicle equipment for installation in a vehicle, a portable communication terminal configured to communicate with the in-vehicle equipment, and a server apparatus configured to communicate with the portable communication terminal, the data communication method comprising the steps of:

(a) the portable communication terminal transmitting a request signal that requests voice data representing an email message, to the server apparatus when the portable communication terminal receives an email that has been sent to the portable communication terminal;
