향후 다양한 무선/이동 액세스 네트워크가 서로 연동하여 동작하는 환경에서 무선자원을 효율적으로 이용하고 사업자 및 사용자의 요구사항을 만족시킬 수 있는 이동/무선 네트워크를 위한 연동구조가 요구된다. 이에 본 고에서는 IEEEP1900.4및 IEEE 802.21에서 제시하는 표준기술을 이용하여 Smart Radio 시스템의 구조 및 Universal Access를 위한 Framework를 제안하고 동작 시나리오 및 기능 모듈간의 연동절차를 제시한다. 또, 제안된 시스템구조 및 Framework의 기능 및 성능을 분석하기 위해서 시스템수준 시뮬레이터를 설계/구현에 대해서 기술한다. 성능분석의 결과, 제안한 시스템 연동구조 및 Framework를 이용할 경우, 이동단말은 액세스 네트워크의 통신환경을 자율적으로 인지할 수 있었으며 무선자원을 효율적으로 이용할 수 있었다.
