US 2014/0194115 A1 · METHOD FOR DISCOVERY IN DEVICE-TO-DEVICE COMMUNICATIONS AND APPARATUS FOR THE SAME

Abstract

A method for discovery in device-to-device communications and an apparatus for the same are disclosed. The method performed in a device-to-device server supporting device-to-device discovery between a discovery terminal and a discoverable terminal may include receiving a device-to-device discovery participation message from the discoverable terminal, requesting a gateway to measure a proximity between the discovery terminal and the discoverable terminal, receiving a proximity measurement result from the gateway, and requesting the discovery terminal and the discoverable terminal to initiate a procedure of device-to-device discovery when the proximity measurement result satisfies a predetermined threshold. Thus, the procedure of device-to-device discovery may be performed efficiently.
