Abstract

To support seamless IPTV services in IP-based wireless network, delay or interruption time must be minimized because noticeable interruption will make IPTV service users unhappy. A number of protocols have been proposed for solving mobility problem. However effective seamless handover mechanism to support mobile IPTV services yet to be solved. Mobile WiMAX offers a wireless solution in the access networks that can support IPTV services. Goal of this paper is to identify some reasons of delay time during handover process in an IPv6 capable Mobile WiMAX and to perform handover delay of some optimization scenarios given by existing standardization and proposed improvement.

IP기반의 무선 네트워크에서 원활한 IPTV 서비스를 지원하기 위해, 뚜렷한 중단이 IPTV 사용자들을 불쾌하게 만들기 때문에 지연 또는 중단시간을 최소화해야 한다. 다수의 프로토콜들이 이동성의 문제를 해결하기위해 제안되었지만 모바일 IPTV 서비스를 지원하기 위한 효과적이고 원활한 핸드오버 방법은 아직 풀어야 할 문제이다. 모바일 WIMAX는 IPTV 서비스를 지원할 수 있는 액세스 네트워크에서 무선으로 해결하는 방법을 제안한다. 본 논문의 목표는 모바일 WIMAX가 가능한 IPv6에서의 핸도오버 과정 동안 지연시간의 몇 가지 이유를 확인하는 것, 기존의 표준화에 의해 주어진 몇 가지 최적의 시나리오에 의한 핸드오버 지연을 개선방법을 제안한다.
