Abstract
최근 이동성 기술이 발달함에 따라 사용자들은 언제, 어디서나 어떠한 단말에서도 멀티 서비스를 제공받기 원한다. 사용자들의 욕구를 충족시키기 위해 단기간에 네트워크의 전체를 재설계 하거나, 서비스 망 영역을 확대하는 것에는 비용부담이 발생한다. 이에 IEEE, IETF에서는 이기종 망간의 핸드오버를 활용하는 기술방안을 제안하고 있다. 본 논문은 IEEE 802.21 의 MIH 정보서버를 네트워크의 기반으로 하고, 단말에 FMIPv6의 장점을 이용하여 L3계층의 핸드오버과정을 최적화하는 개선된 핸드오버 방안을 제안하고, 시뮬레이션을 통해 다른 핸드오버 알고리즘과 비교하였다. As the recent development of mobile technology, users want to multi-service in anytime, anywhere, any terminal. To meet the needs of users, it causes a lot of expense that redesign of the entire network or expand the network of services areas. Therefore, IEEE, IETF is offering Handover technology between heterogeneous network. In this paper, the IEEE 802.21 MIH information server is based on the network. It proposes an improved handover that L3 layer to optimize the handover process use of FMIPv6 and executes simulation.
