摘要
客运专线对GSM-R切换提出了更高要求,分析切换的基本原理,根据GSM-R无线网络线状覆盖的特点,提出利用(CI,TA)定向坐标法和TA定向法判定列车运行方向,设计新邻小区列表,得到一种适合于客运专线的快速切换算法。
Passenger special line puts higher requirements for handover in GSM-R system. Basic principles of handover are analyzed. According to the characteristics of radio linear coverage of GSM-R network along railway, a mcthod of using （CI, TA） coordinates and TA to decide the direction of moving trains is figured out. With the setting of a new neighboring cell list, a fast handover arithmetic suitable for passenger special line is devised.
