사용자 단말(UT)과 저궤도(LEO) 위성 사이의 속도 차이가 크기 때문에 이동하는 위성 빔 가장자리에서 UT가 자주 핸드오버되는 문제를 해결해야 합니다. 게다가 LEO 위성통신의 발달로 별자리의 규모와 UT의 수가 엄청나게 증가하고 있다. 따라서 본 논문에서는 UT와 위성의 핸드오버 성능을 향상시키기 위한 위성 핸드오버 전략을 제안한다. 우리는 UT의 경험 품질, 위성의 처리량 및 네트워크의 로드 밸런싱을 공동으로 고려하여 핸드오버의 유틸리티 기능을 정의합니다. 다음으로 UT와 위성의 조합을 표현하기 위한 코딩 방법을 제안한다. 계산 비용을 줄이기 위해 최적의 핸드오버 결과를 찾기 위한 휴리스틱 알고리즘 기반의 접속 및 핸드오버 전략을 제안한다. 마지막으로 시뮬레이션은 제안된 전략의 효율성과 우월성을 보여줍니다.

Abstract: Due to the significant difference in speed between the user terminals (UTs) and the low earth orbit (LEO) satellites, it is necessary to solve the frequent handover of UTs at the edge of the moving satellite beams. Besides, as the development of LEO satellite communications, the scale of constellations and the number of UTs undergoing massive increase. Thus, in this paper, a satellite handover strategy is proposed to improve the handover performances of UTs and satellites. We define the utility function of handover jointly by considering the quality of experience of UTs, the throughput of satellites and the load balancing of network. Then, a coding method is proposed to represent the combinations of UTs and satellites. To reduce the calculational cost, an access and handover strategy based on a heuristic algorithm is proposed to search the optimal handover result. Finally, simulations show the effectiveness and superiority of the proposed strategy.
