Abstract

In shipyard site, a ship is constructed by integrating lots of modules that are made in several sites with different capabilities and specifications. Recently, it needs to make a shipyard to be smart communicating various multimedia information with wired and wireless broadband networks between hierarchical shipyards. In this paper, we propose an additional function of an LTE femtocell local gateway at a remote shipyard, an information exchange method between hierarchical shipyards, and an offload method to separate the general traffic. To reduce traffic of duplicated requests in shipyard, we apply a D2D communication scheme for supporting communication between shipyard equipments without IP service network. Hence, it is expected to increase the productivity of shipyard industry with mobile communications, D2D and broadband Internet technologies.

조선소는 다양한 용량 및 규격을 여러 사이트에서 제작하여 최종통합하기까지 여러 단계를 거치게 되며 이들 사이의 정보공유가 필수적이다. 최근 유무선통신망을 활용하여 조선소의 선박 건조 과정에서 다양한 멀티미디어 정보를 공유하는 조선 산업의 스마트화가 이루어지고 있다. 본 논문에서는 원격에 위치한 조선소에 적용할 수 있는 LTE 기반의 펨토셀 로컬 게이트웨이를 통해 상위 조선소와 중요정보를 주고받는 트래픽과 일반 트래픽을 분리하는 오프로드 방식을 제안하였다. 또한 조선소 내의 중복 요청되는 데이터에 대한 트래픽을 줄이기 위해 D2D 통신 기술을 적용하여 통신사업자의 IP 서비스 네트워크를 경유하지 않고 조선소 내의 기기간 통신을 지원하는 방안을 제안하였다. 이를 통해 이동통신망과 D2D, 광대역 인터넷 활용 기술을 조선 산업에 적용하여 조선소 산업 생산성 향상을 고려하였다.
