Abstract

This paper describes the overview of spectrum requirement estimation recommended in ITU-R Rec. M.1390 and [IMT.METH] and its difference for the IMT mobile service, and a (IMT.METH) methodology is applied to the spectrum estimation of the recent IMT service. The traffic model and traffic calculation algorithm is briefly described for the carried traffic which is determined in terms of the offered traffic, system rapacity, and the criteria of quality of service. And the spectrum requirement demand which is required from year 2010 to year 2015 is calculated as an example for the IMT service which is recently operated and deployed in the current Korean market after obtaining the reasonable market data and the ITU market prediction data.

본 논문은 IMT 이동통신 서비스에 있어서 ITU-R의 권고안 ITU-R M.1390, ITU-R (IMT.METH)에 권고한 주파수 소요량 산출의 개요와 그 차이점을 기술하고, ITU-R (IMT.METH) 방법론을 최근의 IMT 서비스에 대한 주파수 소요량을 산출하는데 적용하였다. 발생 호량(offered traffic)과 시스템 용량, 서비스 품질(quality of service) 기준에 의하여 결정되는 운반 호량(carried traffic)에 대한 모델과 알고리즘을 기술하고 산출예로서 최근에 서비스가 개시되고 있는 IMT의 배치에 따른 2010년부터 2015년까지 국내에서 운용되고 있는 IMT 서비스에 대하여 여러 가지 시장 자료와 ITU의 예측 자료를 통하여 얻은 후 주파수 소요량을 산출하였다.
