Location detection apparatus and method in communication system supporting device-to-device scheme

A first device in a communication system supporting a device-to-device (D2D) scheme, the first device comprising:

• a controller configured to detect a presence of a second device of which location information needs to be detected;
• a transmitter configured to transmit a discovery request message requesting activation of at least one of an urgent discovery operation or a positioning operation;
• and
• a receiver, from at least one device including the second device, configured to receive a discovery response message to the discovery request message,
• wherein the transmitter is configured to transmit, to the second device, information related to performing of the positioning operation.

A first device in a communication system supporting a device-to-device (D2D) scheme, the first device comprising:

• a receiver configured to receive a discovery request message including an application code for activating a positioning operation, and an identifier (ID) of a corresponding device;
• a controller configured to determine the corresponding device to be a second device of which location information needs to be detected;
• and
• a transmitter configured to transmit a discovery response message including a predetermined specific ID,
• wherein the receiver is configured to receive, from the second device, information related to performing the positioning operation by the second device.

A second device in a communication system supporting a device-to-device (D2D) scheme, the second device comprising:

• a receiver configured to receive, from a first device, a discovery request message requesting activation of at least one of an urgent discovery operation or a positioning operation;
• and
• a transmitter configured to transmit, to the first device, a discovery response message to the discovery request message,
• wherein the receiver is configured to receive, from the first device, information related to performing the positioning operation, and
• wherein the second device is a device of which location information needs to be detected.

A second device in a communication system supporting a device-to-device (D2D) scheme, the second device comprising:

• a transmitter configured to transmit a discovery request message including an application code for activating a positioning operation, and an identifier (ID) of a corresponding device;
• and
• a receiver configured to receive a discovery response message including a predetermined specific ID from the first device,
• wherein the transmitter is configured to transmit, to the first device, information related to performing the positioning operation by the second device, and
• wherein the second device is a device of which location information needs to be detected.
