Abstract

This paper presents the results of research on developing marine unified communications to provide VoIP service based on marine satellites. With the recent popularity of smart-phones and other mobile devices, the demand for Internet-based wired and wireless unified technology has been growing in marine environments, and increasing interest is being directed to VoIP products and service models with high price competitiveness and the ability to deliver a variety of services. In this regard, this research designed three instruments, developed their unit modules, and verified their performances. These three instruments included the following: (1) a marine VoIP module equipped with an analogue gateway that can be linked to the existing devices used in vessels, which is more than 80% smaller than that of a land system; (2) a text/voice/video engine for marine satellite communications that runs on technology that minimizes communication data usage, which is a core technology for a marine VoIP service; and (3) a unified communication service that can support multilateral cloud-based message conversations, telephone number-based call functions, and voice/video calling between a private space in a ship and shore.

본 논문에서는 해사위성기반의 VoIP 서비스를 위한 해상용 통합 커뮤니케이션 기술 개발에 관한 연구를 수행하였다. 최근 스마트폰과 모바일기기가 대중화되면서 해상에서도 인터넷기반 유무선 통합기술의 수요가 증가하고 있으며, 특히 가격 경쟁력이 높고 다양한 서비스를 제공할 수 있는 VoIP 제품과 서비스 모델에 대한 관심이 높아지고 있다. 따라서 본 논문에서는 첫째, 아날로그 게이트웨이 모듈을 장착하여 기존 선박용 장비와 연동이 가능하며 육상용 시스템 대비 80%이상 소형화 된 해상 VoIP 모듈을 개발하고 둘째, 해상용 VoIP 서비스 핵심요소기술인 통신 데이터 사용량 최소화 기술이 적용된 해상위성통신용 텍스트/음성/영상 엔진을 개발한다. 마지막으로 다자간 메시지 및 클라우드 방식의 메시지 대화지원, 전화번호 기반의 통화기능 지원과 개인 공간에서 육상과 음성 및 영상통화 지원이 가능한 해상용 통합 커뮤니케이션을 설계하고 단위 모듈을 개발하여 성능을 검증하였다.
