Abstract

South Korea decided to use the public safety long term evolution (PS-LTE) method to build a wireless communications network for national disaster. The move will allow all disaster management agencies, including police, firefighters and the military to use multimedia information, including videos, in addition to voice to carry out rescue operations from 2017. The Ministry of Science, ICT and Future Planning said Thursday that it adopted PS-LTE as the technology method for national disaster management system following a national policy coordination meeting last month. PS-LTE is a method integrating group communication, direction communication between terminals and independent base station function with existing LTE technology. Until now, disaster management agencies used technology that only allowed voice communication. However, transmission of multimedia information is possible using PS-LTE.

국가재난안전통신망 구축사업 기술방식으로 공공안전 롱텀에볼루션(PS-LTE) 방식이 선정됐다. 이를 통해 2017년부터 경찰, 소방, 군 등 모든 재난안전 책임기관이 음성뿐 아니라 동영상 등 멀티미디어 정보를 활용해 구조활동을 벌일 수 있게 됐다. PS-LTE는 기존 LTE 기술에 그룹통화, 단말기 간 직접통신, 단독 기지국 기능 등이 추가된 방식이다. 지금까지 각 재난안전기관이 사용하던 통신기술은 음성만 전달할 수 있었다. PS-LTE 기술을 이용하면 멀티미디어 전송이 가능해진다. 본 논문에서는 해외 주요국에서 추진 중에 있는 광대역 공공안전통신정책 기술동향을 분석하고, 이를 통해 국내 광대역 공공안전통신 도입 시 고려해야 할 사항을 알아보았다.
