Abstract

TETRA system has been developed focusing on the supporting high-speed and high-capacity data transfer and improving the wireless technology. Hence, TETRA over IP technology became the important basis for supporting compability with various network wireless technologies and high-speed data transfer technologies. For advancing the current TETRA system based on IPv4 network, introduction of IPv6 protocol is necessary. In this paper, we propose an optimized scheme to support IP mobility to IPv6 node when IPv6 protocol is applied to the enviroment ingreated WLAN and TETRA networks. We proposed two scheme using MIPv6 protocol and HMIPv6 protocol respectively. Then, we evaluate performance of the proposed schemes and anlayze the results in order to derive the optimized scheme for the environment integrated WLAN and TETRA networks.

TETRA 시스템은 현재 고속 데이터 전송, 대용량 데이터 전송 지원, 무선 기술 향상에 초점을 맞추어 연구 및 개발되고 있다. 이에 따라 부각된 IP 네트워크 기반 TETRA 시스템은 다양한 네트워크 무선 기술들과의 상호 호환성 제공 및 초고속 무선 데이터 전송 기술 지원에 중요한 발판이 되었다. 현재의 IPv4를 기반으로 한 TETRA 시스템의 향상을 위해서는 IPv6의 도입이 필수적이다. 본 논문에서는 WLAN과 TETRA 네트워크의 통합 환경에서 IPv6를 도입하였을 때 단말에 IP 이동성을 제공하기 위한 최적의 방안을 제안한다. MIPv6를 적용할 방안과 HMIPv6를 적용한 방안을 제안하였고, 제안한 방안들의 시그널링 비용과 랜드오버 지연을 측정하고 비교하여 최적화된 방안을 도출하였다.
