Abstract

Advances in mobile communication and digital video technology enable to commercialize converged multimedia services such as VoD in the mobile networks. Media convergence is evolving into U-Cloud and mobile IP-TV services constituted by high-speed mobile multimedia networks and integrated personal devices. This paper proposes a resource allocation scheme to guarantee QoS of converged mobile multimedia services, and simultaneously maximize legacy services in heterogeneous wireless networks. Performances are analyzed by the simulation.

이동통신과 디지털 영상처리 기술의 발전에 의해 음성통신, WWW, e-mail, FTP 등 전통적 서비스 이외에 VoD 등 융합형서비스가 이동통신망에서도 상용화되고 있다. 이러한 융합형 서비스는 LTE-Advanced 네트워크 등 초고속 이동 통신망과 통합형 휴대 단말기를 바탕으로 U-cloud 서비스, 모바일 IP-TV 등으로 진화될 것 이다. 본 연구에서는 이종 융합 무선망에서 음성통신, VoD, 영상통화 등 실시간 서비스의 품질을 허용 가능한 수준으로 보장하면서도 무선자원의 활용도를 높여 WWW 등 기존의 비실시간 인터넷 서비스를 최대한 수용하기 위한 방안을 제안한다.
