Abstract

Current cellular systems rely on a CBS protocol for emergency alert broadcast services. However, the CBS protocol just specifies the delivery of a limited text message. Therefore, foreigners, who are unfamiliar with local characters, may have some difficulties in understanding the received CBS text message. The CBS protocol also reveals a distinct restriction in delivering abundant information because of a limited number of text characters. In order to overcome the weak points of the current CBS protocol, we propose a display method of image information and URL on the screens of mobile terminals for the received CBS text message in this paper. The presented approach effectively utilizes the message structure of CBS for 5G cellular systems.

현 이동통신 시스템은 재난경보 방송을 위하여 CBS 프로토콜을 이용한다. 그러나 CBS 프로토콜 표준은 제한된 텍스트 문자의 전송만을 규정하고 있다. 따라서 국내 문자에 익숙하지 않은 외국인 등은 수신된 메시지를 충분히 이해하기 어려운 단점이 있다. 또한, 현 CBS는 메시지의 글자수 제한으로 자세한 정보를 전송하기 어려운 한계를 가진다. 이러한 어려움을 극복하기 위하여 본 논문에서는 CBS 재난문자 전송시 단말기에서 이미지 정보 와 URL을 표출하는 기법을 제안한다. 이 기법은 5G 이동통신을 위한 CBS의 메시지 구조를 이용한다. 이 메시지 구조를 이용할 경우 CBS 프로토콜은 문자 코딩방식에 관계없이 단말기에서 이미지 정보와 URL을 표출할 수 있음을 보인다.
