Performance Analysis Of High-Speed Railway Handover Scheme With Different Network Architecture
ieee joint international information technology and artificial intelligence conference(2019)
Abstract
With the rapid development of high-speed railway technology, its velocity is getting higher. As an important part of high-speed railway wireless communication system, handover has become one of the focuses of research in the field of highspeed railway. Due to the high mobility of the high-speed railway, it brings problems such as signal instability and frequent switching to the high-speed railway handover, which often lead to intermittent interruption of communication, and result in a sharp drop in communication quality. In this paper, we analyze the handover performance under different handover conditions and handover modes in LTE and distributed antenna system. In addition, we establish a probability model to analyze the handover performance, and compare the handover performance under different conditions.
