Abstract

최근 이동통신 시스템은 WCDMA(wideband code division multiple access)를 기반으로 다양한 멀티미디어 서비스를 지원하고 있다. 2013년 11월 통계에 따르면 국내 이동통신 가입자 수는 피처폰과 스마트폰 사용자를 모두 합하여, 5451만4397명으로 분석되었다. 따라서 이동통신 서비스 이용자는 이미 전체 인구수를 400만 명이상을 추월했다. 이동통신 가입자의 급격한 증가로 인해 이동통신 서비스 망의 운용과 분석은 무엇보다 중요하며, 그에 따른 서비스 품질도 다양하게 연구되고 있다. 본 논문에서는 CDMA(code division multiple access)를 기반으로 하는 피처폰과 WCDMA를 기반으로 하는 스마트폰의 안정적인 서비스 지원을 위하여 이동통신망의 채널용량을 산출할 수 있는 시뮬레이터를 구현하고, 시뮬레이터를 이용하여 이동통신 서비스 환경에 따른 다양한 채널용량 특성을 분석하였다. Recently mobile communication systems have supported various multimedia services based on wideband code division multiple access (WCDMA). In November 2013, the statistics reported that the domestic subscriber number of mobile communication systems was totally 54 million 514 thousand 397 in using feature phones and smart phones. Therefore, the user number of mobile communication services has surpassed over 4 million rather than the whole number of population. The sharp increase of the mobile user number has made the network management and analysis for mobile communication services more important than before. Besides, the service quality has been studied in various ways. This paper has implemented the simulator calculating the channel capacity of mobile communication systems to support secure and stable services for both feature phones on CDMA and smart phones on WCDMA. By using the simulator, this paper has analyzed the characteristics of the various channel capacity in mobile communication environments.
