- W1981266406 abstract "최근 국내의 3G 서비스가 본격적인 성장 단계로 들어섬에 따라 트래픽 증가율에 따른 주파수 소요량 변화가 매우 커지고 있다. 따라서 이동 통신 주파수의 재분배가 활발히 검토되고 있는데 우선적으로 정확한 주파수 소요량 산출 방법이 요구된다. 그러나 기존 산출 방법은 현재의 실질적인 데이터 분석보다 미래의 서비스 예측에 의존하고 있다. 본 논문에서는 실질적인 데이터 분석에 의한 보다 정확한 주파수 소요량 산출 방법을 제시하기 위해 국내 3G 이동 통신 서비스의 실제 트래픽 특성 및 3G 이동 통신 서비스용 주파수 소요량 산출에 알맞은 알고리즘을 분석하고, 주파수 소요량 산출에 필요한 파라미터를 구하였다. 2007년말 실제 트래픽 파라미터에 근거하여 향후 4년간 데이터 트래픽이 각각 매년 44 % 및 매년 21 %씩 증가하는 경우에 따른 주파수 소요량을 산출하였다. 주파수 소요량 산출 결과는 2011년말까지 매년 44 % 증가하는 경우 약 90 MHz, 매년 21 % 증가하는 경우 약 60 MHz로 나타났다. Recently, as the 3G services of Korea have stepped into the developing stage and the traffic has been rapidly increasing, the spectrum requirements have been getting very large. Therefore spectrum reforming is considered actively and firstly exact methodology of spectrum requirement estimation is needed. But existing methodology depends on the future's service forecast than the present substantial data. This paper proposed the exact methodology of spectrum requirement estimation is based on the real data. So this paper analyzed the characteristics of Korean mobile communication traffic based on the real data and the algorithm suitable for estimation of spectrum requirements for 3G mobile communications, and calculated the parameters needed to estimate the spectrum requirements. Based on the traffic parameters of December 2007, simulations to Bet the estimation of annual spectrum requirements were implemented for the two different cases: one of which is 44 % annual increase in the data traffic and the other is 21 % annual increase. The simulation results show 90 MHz for the first case and 60 MHz for the second case in December 2011." @default.
