Abstract: An apparatus and method for merging acoustic object information to provide an Augmented Reality (AR) service in which real images are merged with sounds. The acoustic object information merging apparatus includes an acoustic objectization unit, an acoustic object information creator and a merging unit. The method classifies sounds received in a microphone array to identify an object corresponding to the received sound. If there is a failure to identify an object for each sound, then a band-pass filter is applied to secondarily classify the received sounds. Acoustic object information is created and merged with a captured image or recorded sound. The acoustic object information may include additional information about the object identified as corresponding to the received sound.

Abstract: A power control method for a mobile communication system includes determining a signal quality of a backward channel between a base station and mobile terminal and then transmitting a power control signal to a terminal to temporarily suspend backward power control of the terminal if the signal quality is stable. When the signal quality is maintained at a stable level, subsequent power control signals including information and/or data are transmitted to the terminal. As a result, transmission efficiency is improved and unnecessary backward power controlling is prevented.
