Abstract

This paper proposes a location-based inter-beam handover event considering terminal mobility to enhance the service quality for terminals in satellite networks. The terminal continuously measures the distance between the serving cell and neighboring cell centers, and checks whether the handover event condition is satisfied, taking into account the terminal's velocity. Performance analysis results demonstrate that the proposed location-based handover event reduces the frequency of unnecessary handover event triggering compared to the conventional received signal strength-based handover event, thereby improving the service continuity of the terminal.

본 논문은 위성 네트워크에서 단말의 서비스 품질을 향상시키기 위하여 단말의 이동성을 고려한 위치 정보 기반 빔 간 핸드오버 이벤트를 제안한다. 단말은 서빙 셀과 이웃 셀 중심 사이의 거리를 실시간으로 측정하고 단말의 이동 속도를 고려하여 핸드오버 이벤트 조건을 만족하는지 확인한다. 성능 분석 결과 기존의 수신 신호 세기 기반 핸드오버 이벤트보다 제안하는 위치 정보 기반 핸드오버 이벤트가 불필요한 핸드오버 트리거 이벤트 발생 빈도를 감소시켜 단말의 서비스 지속성을 향상하는 것을 확인하였다.
