摘要： Disclosed herein are an apparatus and method for providing communication services. The apparatus includes a location information acquisition unit, a radio station information acquisition unit, and an offloading unit. The location information acquisition unit acquires information about the current location of the user terminal by sending a location information request message to the user terminal. The radio station information acquisition unit requests information about a white space radio station from which the user terminal can receive the communication services by sending the information about the current location of the user terminal to a white space server, and acquires, from the white space server, information about an available white space radio station. The offloading unit sends the information about the available white space radio station to the user terminal, and also sends information about the user terminal to the available white space radio station.
