    Abstract: Disclosed is a unified speech and audio coding (USAC) audio signal encoding/decoding apparatus and method for digital radio services. An audio signal encoding method may include receiving an audio signal, determining a coding method for the received audio signal, encoding the audio signal based on the determined coding method, and configuring, as an audio superframe of a fixed size, an audio stream generated as a result of encoding the audio signal, wherein the coding method may include a first coding method associated with extended high-efficiency advanced audio coding (xHE-AAC) and a second coding method associated with existing advanced audio coding (AAC).

    Abstract: Disclosed is a method of receiving, by a terminal, an additional network service provided through a temporary base station disposed temporarily or locally in order to transfer disaster information, including: receiving information on the additional network through an existing network service provided by a base station; verifying whether the terminal is handed over to the additional network based on the information on the additional network; and receiving the additional network service through the additional network. According to the present invention, even when a communication service disability occurs due to a flood of telephone traffic in an area where a disaster situation or an event occurs, a communication service can be provided through the additional network in terms of the communication service and a broadcasting channel that provides information specific to the disaster situation or event can be temporarily or locally additionally provided.
