차세대 해상통합 통신망 도입에 관한 연구

Abstract

The environment of communications network at sea has been growing rapidly along with the development of relevant technologies including information technology and radio communication technique. The growth of communication network enables people who are at work in the maritime industries to receive technical benefits widely. Regardless of their locations, anyone who is within the service area could get a way to communicate information with the other through telecommunication satellites, several kinds of radio communication stations and other wireless Internet service networks.

In the waters around the Korean Peninsula, several types of communication systems, including cellular-phone system, MF/HF/VHF transceiver and satellite's terminals, have been mainly used in order to transmit or receive information necessary for safe navigation. However, those systems have their own limitations on the range of service area, the capacity for communication and the price for using them. The cell-phone could provide high data rates and convenience for data transmission, but it could be usable only near shore or in port areas. The MF/HF/VHF transceiver has wider range than the cell-phone, however the capacity of data transmission is limited. And the satellite is covering the entire ocean surface, but it is rather expensive to use.

And because those communication systems were installed separately in the initial stage without considering the efficiency of integration, it was difficult to increase the efficiency in data transmission by exchanging necessary information with each others. And heavy cost of construction was also not evitable to install them. On the one hand, recently a new communication technology, called Next Generation Network, has been introduced and developed rapidly, so as to make communication possible regardless of types of terminal unit.

In this paper, a method was proposed for integrating maritime communication systems which help improve the current environment of communications network at sea. With the results of analyzing both current situation of communications at sea and new advanced technology mainly used in the life on land, an architecture and needed functions of the integrated maritime communication system were defined. Also how to introduce such system into the Korean maritime industries and how to provide adequate services with them were presented. The proposed communication system would be expected to help improve not only the efficiency of communication at sea, but also the navigational safety of vessels engaged in shipping and fishing industry.
