Abstract

A method for performing discovery at a terminal in a communication system is provided. The method includes generating a discovery request message including discovery target information, transmitting the discovery request message to a Proximity Service (ProSe) server that is located in a core network of the communication system and that manages communication of the terminal, and receiving a result of a discovery operation from another entity that performs the discovery operation of the terminal using discovery identification information about the terminal. The other entity is selected based on the discovery target information by the ProSe server.

Description

technical field [0001] This disclosure relates to schemes for discovery. More specifically, the present disclosure relates to remote discovery methods and apparatus in communication networks. Background technique [0002] Recently presented Device-to-Device (D2D) communication refers to communication between devices via a direct link without the intervention of a network entity such as a base station (BS). [0003] A D2D service supporting device (eg, a D2D device) acquires synchronization with a neighboring D2D device, detects or discovers the neighboring D2D device in a predetermined resource at a predetermined time, and acquires device information on the discovered neighboring D2D device. [0004] The device information may include identification information on neighboring D2D devices, interest information, and application information. If the D2D device interacts with the BS, the D2D device discovers neighboring D2D devices at a time set by the BS in resources pre-alloc...
