Abstract

A method and apparatus for traffic safety are provided using vehicle driving-related information obtained on the basis of a transmission/reception beam pair of a road side unit (RSU) and a vehicle on-board unit (OBU), thereby reducing a probability that vehicle collisions occur where visual fields may be obscured. The method includes setting a path from a current location of the electronic device to a destination, and transmitting a message indicating an emergency situation to other devices located on the path while moving to the destination. The method further includes determining a transmission/reception beam pair of the electronic device and a road apparatus, using a reference signal received from the road apparatus, transmitting a signal including information for the transmission/reception beam pair to the road apparatus, and receiving, from the road apparatus, a message warning that the electronic device and another neighboring electronic device are approaching each other.

First claim

What is claimed is:

1 . A method of an electronic device, the method comprising:
setting a path from a current location of an electronic device to a destination; and transmitting a message indicating an emergency situation to at least one other device located on the path while moving to the destination.

2 . The method of claim 1 , wherein the transmitting of the message indicating the emergency situation to the at least one other device located on the path comprises:
acquiring information for the at least one other device located on the path; and requesting a traffic signal control from the at least one other device on the basis of the information while moving to the destination, wherein the information for the at least one other device comprises at least one of a location of the at least one other device, identification information of the at least one other device, and an authentication key for the at least one other device.

3 . The method of claim 2 , wherein the message indicating the emergency situation comprises at least one of:
speed information of the electronic device, current location information of the electronic device, path information from a current location of the electronic device to a destination, service type information for the emergency situation, identification information of the at least one other device, and authentication information of the at least one other device.

4 . The method of claim 2 , wherein the transmitting of the message indicating the emergency situation to the at least one other device located on the path comprises:
transmitting the message indicating the emergency situation to the at least one other device on the basis of a distance between the electronic device and the at least one other device.

5 . A method of a traffic signal apparatus, the method comprising:
receiving a message indicating an emergency situation from an electronic device; and controlling a traffic signal of the traffic signal apparatus in response to the message indicating the emergency situation.

6 . The method of claim 5 , wherein the controlling of the traffic signal of the traffic signal apparatus in response to the message indicating the emergency situation comprises:
acquiring speed information of the electronic device and current location information of the electronic device from the message indicating the emergency situation; determining a control time of the traffic signal on the basis of at least one of the speed information of the electronic device and the current location information of the electronic device; and providing a predetermined traffic signal during the control time.

7 . The method of claim 5 , further comprising:
acquiring authentication information from the message indicating the emergency situation; and identifying a traffic signal control right of the electronic device on the basis of the authentication information and an authentication key.

8 . A method of a traffic server, the method comprising:
receiving, from an electronic device, current location information and destination information of the electronic device; setting a path of the electronic device on the basis of the current location information and the destination information; acquiring information on at least one traffic signal control apparatus located on the path; and transmitting, to the electronic device, information on the path and the at least one traffic signal control apparatus, wherein the information on the traffic signal control apparatus comprises at least one of:
a location of the at least one traffic signal control apparatus,
identification information of the at least one traffic signal control apparatus, and
an authentication key of the at least one traffic signal control apparatus.

9 . A method of an electronic device, the method comprising:
determining a transmission/reception beam pair of an electronic device and a road apparatus, using a reference signal received from the road apparatus; transmitting a signal including information for the transmission/reception beam pair, to the road apparatus; and receiving a message, from the road apparatus, warning that the electronic device and another electronic device are on paths to collide with each other.

10 . The method of claim 9 , further comprising:
detecting whether the road apparatus transmitting the reference signal exists on a path of the electronic device; activating a receiver of the electronic device when the road apparatus transmitting the reference signal exists on the path of the electronic device; and receiving the reference signal from the road apparatus while changing a reception beam direction of the electronic device.

11 . A method of a road apparatus, the method comprising:
receiving, from an electronic device, a first message including identification information of the electronic device and information for a transmission/reception beam pair; determining whether the electronic device approaches a road position on the basis of the identification information of the electronic device and the information for the transmission/reception beam pair; and transmitting a message to at least one other electronic device notifying of the approaching electronic device when the electronic device is approaching the road position.

12 . The method of claim 11 , wherein the transmitting of the message to the at least one other electronic device comprises:
identifying whether there is another electronic device other than the electronic device approaching the road position; and transmitting the message notifying of the approaching electronic device to the other electronic device which is approaching the road position.

13 . The method of claim 12 , further comprising transmitting the message notifying of the other electronic device approaching the road position to the electronic device.

14 . The method of claim 11 , further comprising:
receiving a second message including identification information of the electronic device and the information for the transmission/reception beam pair, from the electronic device; and determining that the electronic device exits from the road position, when the information for the transmission/reception beam pair received from the electronic device in the second message is changed relative to the information for the transmission/reception beam pair received from the electronic device in the first message.

15 . An electronic device comprising:
a controller configured to:
set a path from a current location of the electronic device to a destination; and
transmit a message indicating an emergency situation to at least one other device located on the configured path while moving to the destination; and
a transmission/reception unit configured to transmit the message indicating the emergency situation to the at least one other device.

16 . The electronic device of claim 15 , wherein the controller is further configured to:
acquire information for the at least one other device located on the configured path; and request a traffic signal control from the at least one other apparatus on the basis of the acquired information while moving to the destination, wherein the information for the at least one other device comprises at least one of a location of the at least one other device, identification information of the at least one other device, and an authentication key for the at least one other device.

17 . The electronic device of claim 16 , wherein the message indicating the emergency situati
