Classification: CPC H  G | IPC G  H

Claim 10:
11. A method for operating a first electronic device comprising a communication circuitry, the method comprising:
receiving, from a second electronic device operating as a relay node, a signal for indicating to transmit a test signal via a device-to-device (D2D) communication path between the first electronic device and a third electronic device to the third electronic device, the signal is transmitted from the second electronic device to the first electronic device in response to they second electronic device detecting that a communication path between the second electronic device and the third electronic device is disconnected;
in response to the reception of the signal transmitting the test signal via the D2D communication path to the third electronic device;
in response to the reception of the signal, activating a timer for monitoring whether a response signal regarding the test signal is received or not;
based on identifying that the response signal is received from the third electronic device before the activated timer is expired, transmitting, to the second electronic device, a first message for indicating that a vehicle comprising the third electronic device is not in an emergency situation; and
based on identifying that the response signal is not received from the third electronic device until the activated timer is expired, transmitting, to the second electronic device, a second message for indicating that the vehicle comprising the third electronic device is in the emergency situation.
