초록

고속철도시스템은 열차의 안전운행에 요구되는 각종 신호의 공급 및 정보의 교환을 위해 LTE를 기반으로 하는 LTE-R 방식의 이동통신기술을 사용하고 있다. 본 논문에서는 LTE-R 기반 고속철도통신에서 전송되는 응용트래픽의 전송성능을 분석하고, 이를 토대로 고속철도통신의 응용트래픽 운용 조건을 살펴본다. 성능 분석은 NS-2를 기반으로 하는 컴퓨터 시뮬레이션을 사용하며, VBR, CBR 등의 전송성능을 측정한다. 전송효율, 지연, 패킷손실율 등을 성능 측정 및 분석 파라미터로 사용한다.

LTE-R mobile communication technology based on LTE is used to supply various signal and exchange information required for safety operation of train on high speed railway communication system. In this paper, transmission performance of application traffic which is transferred on high speed communication based on LTE-R is analyzed. And some suggestions for application traffic transmission of high speed railway communication will be considered. Computer simulation is used to analyze performance of CBR, VBR as application traffic. Throughput, delay and packet loss rate is used as performance measurement and analysis parameters.
