본 논문은 UHD 모바일 환경에서 서비스 핸드오프를 위한 관련 파라미터를 DNS 프로토콜을 적용하여 통신망을 통해 제공하기 위한 서비스 핸드오프 제공 방법에 관한 것이다. 이를 위해 본 논문에서는 DNS 기반 서비스 핸드오프 프레임워크를 기술하고, 관련 기능을 검증하기 위한 서비스 핸드오프 송신 플랫폼과 RF 간 또는 RF 와 브로드밴드 간 핸드오프를 처리하기 위한 수신 플랫폼을 소개하고자 한다. 제안한 방법을 적용할 경우 지상파 UHD 모바일 수신기에 브로드밴드 모듈이 탑재될 경우, 사용자의 이동 동선에 최적으로 서비스 핸드오프 정보를 적응적으로 제공할 수 있어 핸드오프 성능을 향상시킬 수 있다.
