미래전의 전투 양상 변화에 따라 우리군은 다계층‧다차원의 통신체계 구축을 추진하고 있으며, 특히 공중계층을 통해 무선전송 중계를 지원하는 릴레이망 확보를 위해 노력하고 있다. 본 논문에서는 공중 릴레이 구조 및 각 구성 요소들을 설명하고, 릴레이 구조에 따른 중계기 특징을 살펴보았다. 또한 공중 릴레이 망의 최신 연구사례를 단일, 다중, 다체계, 게이트웨이의 4가지로 사례로 분류/분석하고, 공중 릴레이 망에서 발생할 수 있는 통신기술 이슈를 OSI 계층별로 나누어 정리하였다. 배포된 공중 릴레이망의 운영간 발생 가능한 시스템 운영 이슈를 통합관리와 서비스 측면에서 분석하고, 분석 내용을 바탕으로 최근 연구가 활발히 논의 되고 있는 6G 기술 발전 방향과 더불어 공중 릴레이망 진화방향과 도전과제를 정리하였다.
Abstract
The Korean military is promoting the establishment of a multi-layer and multi-tier communication system to meet the changes in combat patterns of future warfare, and in particular, is striving to achieve a relay network that supports wireless transmission and broadcasting through airwaves. In this paper, we explained the structure of the airborne relay and its components. The characteristics of the relay nodes according to the relay structure are examined. In addition, the latest research cases of airborne relay networks are classified into four cases: single, multiple, multi-system, and gateway, and communication technology issues that may occur in airborne relay networks are classified by OSI layer. The possible system operation issues between the operations of the deployed airborne relay network were analyzed in terms of integrated management and service. Based on the analysis, the direction of development of 6G technology, which has been actively discussed recently, and the direction of evolution and challenges of the airborne relay network were summarized.
