Abstract: Disclosed is an advertising service method using D2D communication for efficiently using limited radio resources and control channel resources. The advertising service method includes setting a D2D common bearer with a network, receiving advertising terminal information from at least one other advertising terminal through the D2D common bearer, registering the advertising terminal in the network, transmitting advertising information to the at least one other advertising terminal and a user terminal through the D2D common bearer, and setting a user terminal and a D2D dedicated bearer on the basis of information received from the network. Accordingly, an advertisement can be easily transmitted to a plurality of user terminals which were not previously connected, and a collision between advertising terminals which are located in plurality in a specific area and transmit advertisements can be avoided.

Abstract: A method for setting synchronization between terminals performing device-to-device (D2D) communication based on a cellular communication system is disclosed. The method for setting synchronization between terminals includes receiving a message instructing synchronization setting with an opposite terminal from a base station, selecting a first preamble transmitted for a synchronization setting with the opposite terminal based on the message instructing synchronization setting, transmitting the selected first preamble to the opposite terminal, receiving a second preamble from the opposite terminal, and setting the synchronization with the opposite terminal using a reception timing of the second preamble when the second preamble is a preamble designated in the message instructing synchronization setting. Thus, when the present invention is used, synchronization between two terminals performing direct communication may be set using a physical layer random access channel resource which has been used in an existing mobile communication system.
