Abstract

A wireless communication device adapted for transmitting and receiving information in a wireless access in vehicular environment (WAVE) is proposed. The wireless communication device includes a WAVE module. The WAVE module broadcasts a WAVE announcement frame as a beacon, where the beacon includes a WAVE service information element (WSIE), and the WSIE includes at least record information such as a vehicle number of a vehicle, in which the wireless communication device is located. Another wireless communication device is proposed, which exchanges respective record information with the neighboring vehicle(s) via a connection established between the wireless communication device and the neighboring vehicle(s) after at least a WAVE announcement frame of the neighboring vehicle(s) is received.

Claims

1. A wireless communication device, adapted for transmitting and receiving information in a wireless access in vehicular environment (WAVE), the wireless communication device comprising:

a WAVE module, configured for broadcasting a WAVE announcement frame, wherein the WAVE announcement frame is a beacon, the beacon comprises a WAVE service information element (WSIE), and the WSIE comprises at least record information.

2. The wireless communication device as claimed in claim 1, wherein the at least record information comprises at least a vehicle number of a vehicle, in which the wireless communication device is located.

3. The wireless communication device as claimed in claim 1, further comprising:

an in-vehicle device connection module, connected to the WAVE module, configured for connecting the WAVE module to at least a device of the vehicle, in which the wireless communication device is located;

a record module, connected to the WAVE module, configured for recording the at least record information and a vehicle number of the vehicle; and

a global positioning system (GPS) module, connected to the WAVE module and the record module, configured for obtaining current GPS position information of the vehicle.

4. The wireless communication device as claimed in claim 3, further comprising:

a speed meter, connected to the WAVE module and the record module through the in-vehicle device connection module, configured for providing current speed information of the vehicle to the WAVE module, wherein the record module records the current speed information of the vehicle.

5. The wireless communication device as claimed in claim 3, further comprising:

a collision detection device, connected to the WAVE module through the in-vehicle device connection module, configured for providing a warning message to the WAVE module when a collision event of the vehicle occurs, wherein the WAVE module sends the WAVE announcement frame to at least a neighboring vehicle to notify the collision event.

6. A wireless communication device, adapted for transmitting and receiving information in a wireless access in vehicular environment (WAVE), the wireless communication device comprising:

a WAVE module, configured for broadcasting a first WAVE announcement frame, and continually receiving at least a second WAVE announcement frame broadcasted by at least a neighboring vehicle, wherein the first WAVE announcement frame and the at least a second WAVE announcement frame are beacons, each one of the beacons comprises a WAVE service information element (WSIE), and the WSIE comprises at least record information.

7. The wireless communication device as claimed in claim 6, wherein the at least record information comprises at least a vehicle number of a vehicle, in which the wireless communication device is located.

8. The wireless communication device as claimed in claim 6, wherein, after the WAVE module receives the at least a second WAVE announcement frame, the WAVE module establishes one or a plurality of WAVE connections with the at least a neighboring vehicle.

9. The wireless communication device as claimed in claim 8, wherein, after the WAVE connection or the WAVE connections are established, the WAVE module and the at least a neighboring vehicle exchange the at least record information, wherein the WAVE module encrypts first record information sent to the at least a neighboring vehicle and decrypts second record information sent from the at least a neighboring vehicle.

10. The wireless communication device as claimed in claim 9, further comprising:

an in-vehicle device connection module, connected to the WAVE module, configured for connecting the WAVE module to at least a device of the vehicle, in which the wireless communication device is located;

a record module, connected to the WAVE module, configured for recording the at least record information and a vehicle number of the vehicle; and

a global positioning system (GPS) module, connected to the WAVE module and the record module, configured for obtaining current GPS position information of the vehicle.

11. The wireless communication device as claimed in claim 10, further comprising:

a speed meter, connected to the WAVE module and the record module through the in-vehicle device connection module, configured for providing current speed information of the vehicle to the WAVE module, wherein the record module records the current speed information of the vehicle.

12. The wireless communication device as claimed in claim 11, further comprising:

a collision detection device, connected to the WAVE module through the in-vehicle device connection module, configured for providing a warning message to the WAVE module when the vehicle catches a collision event, wherein the WAVE module sends the WAVE announcement frame to the at least a neighboring vehicle to notify the collision event.
