본 논문에서는 스마트폰 미들웨어 및 기본 응용 프로그램으로 구성된 임베디드 리눅스 기반의 스마트폰 에디션의 구현에 대해 기술한다. 기존의 스마트폰 플랫폼들은 상용화 시 로열티를 지불해야 하고, 소스 코드가 공개되어 있지 않아 기능 확장의 문제점이 있었다. 임베디드 리눅스 기반의 GPE는 상용화 시 로열티 문제점은 해결하지만, PDA 급 장치들을 목표로 개발되어 스마트폰과 같은 작은 LCD 크기 및 키 입력만으로 응용 프로그램을 수행할 수 없는 문제점이 있었다. 구현된 Qplus-P스마트폰 에디션에서는 임베디드 리눅스 기반으로 개발되어 로열티가 없으며, 사용자가 키 입력 만으로 폴더 이동 및 특정 응용 프로그램을 수행할 수 있는 키 네비게이션 기능을 제공한다. 그리고, 기존의 셀룰러폰과 유사한 화면 구조 및 인디케이터를 제공함으로써 사용자가 보다 편리하게 스마트폰 에디션을 사용할 수 있는 환경을 제공한다.
