Abstract

Current disaster alert broadcasting based on mobile communication systems targets personal mobile terminals such as smartphones. However, smart cities require IoT-based services such as smart homes and offices. Therefore, when severe disasters such as earthquakes occur, smart cities must quickly perform appropriate control and respond to buildings and factories. For this, a disaster warning broadcasting technique for IoT terminals for smart cities is required. In this paper, we propose a disaster alert transmission method based on 4G/5G mobile communication for IoT terminals for smart cities. The proposed method effectively utilizes the image display method for CBS, a cell-based broadcasting service, and shows the superiority of the proposed approach through simulation.

이동통신 시스템 기반의 현 재난경보 방송1)은 스마트폰 등 개인 휴대 단말기를 대상으로 한다. 그러나 스마트 시티는 스마트 홈, 스마트 오피스 등 IoT 기반의 서비스를 필수로 한다. 따라서 지진 등 심각한 재난이 발생하면 스마트 시티는 건물, 공장 등에 적절한 제어 및 대응을 신속히 수행할 필요가 있다. 이를 위해 스마트 시티 용 IoT 단말기를 위한 재난경보 방송 기법이 필요하다. 본 논문에서는 스마트 시티 용 IoT 단말기를 위한 4G/5G 이동통신 기반의 재난경보 전송기법을 제안한다. 제안된 기법은 셀 기반 방송 서비스인 CBS를 위한 이미지 표출방식을 효과적으로 활용하며 모의실험을 통해 제안된 기법의 우수성을 보여준다.
