1. A method for a mobile communication system that supports a device-to-device (D2D) communication that is direct inter-terminal communication, comprising:transmitting location information indicating geographical locations of user terminals located in a cell of a base station, from the user terminals to the base station;
allocating, at the base station, radio resources to the user terminals based on the location information, wherein the radio resources are used by the user terminals to transmit a signal for the D2D communication;
notifying the allocated radio resources to each of the user terminals by a unicast manner;
receiving, at each of the user terminals, a unicast signal indicating the radio resources allocated by using the location information, from the base station; and
using the allocated radio resources to transmit the signal for the D2D communication.
