Abstract

Disclosed is a user equipment that supports device-to-device communication. A user equipment according to an embodiment of the present invention comprises: a communication unit for broadcasting a discovery message for informing another user equipment of the user equipment itself, and receiving a discovery message broadcasted from another user equipment; and a control unit for, when at least one discovery message is received, extracting an ID of at least one other user equipment from the at least one received discovery message, selecting at least one ID out of the extracted ID on the basis of status information indicating an importance of the at least one other user equipment, and broadcasting a discovery message including the selected ID.

Description

technical field [0001] Apparatuses and methods consistent with the disclosure herein relate to user equipment and communication methods of user equipment, and more particularly, to user equipment that relays discovery messages of user equipment that support direct communication between devices, and for central The communication method of the subsequent user equipment. Background technique [0002] Recently, much effort is being devoted to the technology of proximity-based services (ProSe) to facilitate direct communication between user equipments by using traditional communication methods of mobile systems without allowing user equipments (UEs) Level entities access the communication network. [0003] Despite the many possibilities utilizing ProSe technology, device-to-device communication between user equipments makes it difficult to ensure the mobility of user equipments unless no network is provided with respect to upper nodes, so that there is a limitation on the possib...
