Abstract: A method in which a base station manages information for D2D communication, which is direct communication between terminals, is provided. The base station receives a first message that requests a configuration of a first open discovery service that searches for a first terminal and at least one terminal to perform D2D communication. The base station determines whether a resource to allocate to the first terminal exists. The base station stores first information for providing the first open discovery service based on the determination result.
