초록

이동통신 사업자들은 자신의 망 총소유비용을 줄이면서 데이터 폭증에 대처하기 위한 다양한 기술적인 대책 들을 강구하고 있다. 이 논문에서는 그러한 기술적인 대책의 하나로써 클라우드 기지국이란 새로운 기지국 구조에서 조정 다중점 송수신 운용에 따른 시스템 용량 및 이동성 성능에 관련된 모의실험 결과를 도출한다. 그 결과는 조정 다중점 송수신이 적용되는 클라우드 기지국의 규모 및 적용 영역에 따라 시스템 용량 및 이동성 성능도 개선될 수 있다는 것을 관찰할 수 있었으며 이러한 상호 인과 관계들은 실제 이동통신 사업자의 망 운용에 있어서 하나의 실용적 지침을 제공할 수 있다.

Mobile operators are considering a variety of technical measures to cope with the explosion of data while reducing TCO(Total Cost of Ownership) of their networks. In this paper, to investigate the possibility about one of such technical measures, system level simulation to evaluate the performance of the capacity and mobility was performed in cloud base station structure to apply coordinated multi-point transmission and reception. As a result, we find out that system capacity and mobility performance may be improved according to the scale and application area of cloud base station with the operation of coordinated multi-point transmission and reception, and these mutual causality can provide practical guidelines to mobile network's operation.
