Location detection apparatus and method in communication system supporting device-to-device scheme
First Claim
1. A method of a first device in a communication system supporting a device-to-device (D2D) scheme, the method comprising:
- transmitting a discovery request message requesting activation of at least one of an urgent discovery operation or a positioning operation upon detection of a presence of a second device of which location information needs to be detected;
receiving, from at least one device including the second device, a discovery response message to the discovery request message; and
transmitting, to the second device, information related to performing the positioning, operation.

Abstract
The present invention relates not only to a fourth-generation (4G) communication system, such as long-term evolution (LTE), but also to a fifth-generation (5G) or pre-5G communication system to be provided to support a higher data transfer rate. The present invention provides a method for a first device in a communication system supporting a device-to-device (D2D) scheme, the method comprising the steps of: when existence of a second D2D device, of which the location information needs to be detected, has been detected, transmitting a discovery request message which requests activation of at least one of an urgent discovery operation and a location measurement operation; receiving a discovery response message to the discovery request message from at least one device including the second device; and transmitting, to the second device, information related to execution of the location measurement operation.
