국내 이동전화 시장은 1990년대 후반 이후 가입자와 매출 측면에서 급성장을 한 이래, 성숙기 진입과 새로운 세대로의 전환기를 맞이하고 있다. 특히, 가입자의 완만한 증가와 이동전화 무선인터넷의 급성장, 번호이동성과 통합 식별번호 이후 가입자의 사업자 전환 증가가 대세적 추세로 나타나고 있으며 2006년 후반기 이후 HSDPA의 3.5세대 영상 이동전화 시대로의 진입이 시작되었다. 이러한 변화와 도약기에서 이동전화 이용자의 특성과 이용 행태를 분석하고 신규 서비스에 대한 수용도를 파악하는 것은 그 의미가 지대할 것이다. 이에 본 고에서는 시장조사 결과를 바탕으로 이동전화와 이동전화 무선인터넷, 번호 이동성과 통합 식별번호에 대한 이용 현황을 파악하고 이용 촉진과 장애요인을 분석하였으며 차세대 이동통신 서비스인 HSDPA에 대한 수요 및 이용의향과 관련된 수용도를 전망하였다.
