摘要:

我国现有的铁路移动通信系统已不能满足铁路信息化建设的要求,需要开展下一代高速铁路通信系统关键技术研究。越区切换是高速铁路宽带无线通信系统的关键技术,对保障列车的行车安全和通信可靠性具有重要意义。针对目前高速铁路通信系统中越区切换技术的研究现状和成果进行总结,分析存在的问题,并进一步探讨未来越区切换技术的发展方向。

关键词: 高速铁路, 越区切换, 无线通信

Abstract:

The existing railway mobile communication system can’t meet the requirements of railway information construction.Therefore,the key technology research of next generation of high-speed railway (HSR) communication system needs to be carried out.Handover is a key technology of HSR broadband wireless communication system,which has great significance to ensure the train safety and communication reliability.The research results of the handover in HSR communication system were summarized and the existing problems were investigated.Furthermore,the development directions of handover in the future were explored.

Key words: high-speed railway, handover, wireless communication
