IEEE 802.21 워킹그룹은 이종 망간 핸드오버인 매체독립 핸드오버뿐만 아니라 라디오 자원 관리 등의 다양한 이종 망 연동이슈를 해결하고자 매체독립 서비스 프레임워크 표준과 이 프레임워크를 기반으로 한 활용사례들에 대한 표준으로 분리하여 표준화를 추진하고 있다. 본 고에서는 IEEE 802.21 워킹그룹의 표준화 동향 및 매체독립 서비스 기술에 대해 알아본다.

It is necessary for maritime multi-band networks, which provide ships with diverse and seamless multimedia services, to perform vertical handover. As IEEE 802.21 WG has standardized vertical handover technologies for terrestrial wireless networks that do not consider VHF, HF, satellite networks, they cannot be directly applied to maritime multi-band networks. In this paper, the vertical handover framework for use in maritime mutlti-band networks is proposed, which includes the logical architecture, the communication reference model, re-defined handover primitives, and the handover process. The proposed vertical handover for maritime multi-band network can be applied in the ocean alone, as well as to the heterogeneous wireless networks which embrace both terrestrial and maritime networks.
