Abstract

An electronic device according to various embodiments may include a communication circuit, including a reception circuit and a transmission circuit, and a processor. The processor may be configured to: receive at least one piece of identification information corresponding to at least one external electronic device for providing a traffic-related signal to at least one vehicle outside the electronic device, via the reception circuit, identify the position of the electronic device, based at least on the at least one piece of identification information, and activate the transmission circuit to transmit movement-related information of the electronic device to the at least one vehicle or the at least one external electronic device, based at least on the position.

Claims

1. An electronic device, comprising:

a communication circuit comprising a reception circuit and a transmission circuit; and

a processor, wherein the processor is configured to;

receive, from at least one external electronic device via the reception circuit, at least one piece of identification information corresponding to the at least one external electronic device which is broadcasted by the at least one external electronic device;

in response to identifying that the at least one external electronic device includes a roadside unit for providing a traffic-related signal to at least one vehicle outside the electronic device based at least on the at least one piece of identification information, activate the transmission circuit to transmit movement-related information of the electronic device.

2. The electronic device of claim 1, wherein the processor is configured to:

determine a distance between the electronic device and the at least one external electronic device; and

adjust an interval of the reception, based at least on the determined distance.

3. The electronic device of claim 1, wherein the processor is configured to include Personal Safety Message (PSM) data as at least a part of the movement-related information.

4. The electronic device of claim 1, further comprising a position measurement module comprising position measurement circuitry,

wherein the processor is configured to:

determine, via the position measurement module, whether a signal associated with position information is received;

activate the reception circuit in response to identifying that the signal is received.

5. An electronic device, comprising:

a communication circuit comprising a transmission circuit and a reception circuit; and

at least one processor, wherein the at least one processor is configured to;

activate the reception circuit in a state in which the transmission circuit is inactivated, to receive, from at least one external electronic device via the reception circuit, at least one of first identification information corresponding to the at least one external electronic device and broadcasted by the at least one external electronic device for providing a traffic-related signal to a vehicle outside the electronic device or second identification information corresponding to the vehicle and broadcasted by the vehicle; and

activate the transmission circuit in response to receiving at least one of the first identification information or the second identification information and transmit a communication signal including at least one of information on position of the electronic device or information on movement of the electronic device.

6. The electronic device of claim 5, further comprising:

at least one sensor module comprising at least one sensor configured to sense the information on movement of the electronic device; and

a position measurement module comprising position measurement circuitry configured to sense the information on position of the electronic device,

wherein the at least one processor comprises;

a first processor; and

a second processor that is connected to at least one of the at least one sensor module or the position measurement module, wherein the second processor is configured to process at least one of the information on movement of the electronic device or the information on position of the electronic device.

7. The electronic device of claim 6, wherein the electronic device is configured such that:

when the first processor is in a sleep state, the second processor is configured to activate the transmission circuit in response to receiving at least one of the first identification information or the second identification information via the reception circuit; and

when the first processor is in a wake-up state, the first processor is configured to activate the transmission circuit in response to receiving at least one of the first identification or the second identification via the reception circuit.

8. The electronic device of claim 7, wherein the second processor is configured to wake up the first processor when at least one of the information on position of the electronic device or the information on movement of the electronic device satisfies a designated condition.

9. The electronic device of claim 7, wherein the electronic device is configured such that:

when the first processor is in the sleep state, the second is configured to transmit a first communication signal including first information via the transmission circuit; and

when the first processor is in a wake-up state, the first processor is configured to transmit a second communication signal including second information, which is different from the first information, via the transmission circuit.

10. The electronic device of claim 9, wherein the first information includes information on a first data field of a plurality of data fields of a Personal Safety Message (PSM), and the second information includes information on a second data field of the plurality of data fields of the PSM;

or

the first information includes first data corresponding to a third data field of the plurality of data fields of the PSM, and the second information includes second data corresponding to the third data field of the plurality of data fields of the PSM.

11. The electronic device of claim 5, wherein the at least one processor is configured to:

identify a distance between the electronic device and the external electronic device, or a distance between the electronic device and the vehicle; and

determine at least one of;

whether to transmit the communication signal, a transmission strength of the communication signal, or a transmission interval of the communication signal, based at least on the distance between the electronic device and the external electronic device or the distance between the electronic device and the vehicle.
