Abstract
A method, apparatus and computer program product are provided to facilitate the establishment of device-to-device communications, such as non-cellular communications or cellular communications in a licensed exempt band. A method and apparatus receive cellular signals including one or more beacon transmission parameters, such as a beacon transmission interval and an identifier, and a beacon transmission status flag. The method and apparatus may also determine that the beacon transmission status flag is set to authorize beacon transmissions and then cause non-cellular beacon signals to be repeatedly transmitted in accordance with the one or more beacon transmission parameters. The method and apparatus may also cause a device-to-device connection to be established following transmission of the beacon signals. The device-to-device connection may be either a non-cellular device-to-device connection or a cellular device-to-device connection.
