摘　　要：为了对基于软硬采信令的高铁LTE模拟路测应用进行研究,首先分析了高铁路线及高铁用户快速发展给运营商通信保障带来的挑战,重点阐述了基于覆盖、质量、干扰、切换、容量的高铁五维分析体系,随后通过搭建软硬采信令平台实现高铁的模拟路测算法,创新高铁小区识别过滤方法、高铁用户识别过滤方法、高铁用户位置定位和切点位置的判断方法,制定高铁LTE模拟路测及优化策略,快速发现天线方位角不准确、切换掉话、干扰等复杂的无线侧隐患问题,并可以有效减少人工路测的成本,具有一定的应用价值。In order to investigate the application of the high-speed railway LTE simulation road test based on soft and hard signaling, challenges brought by the rapid development of high-speed railway lines and users to the operators＇ communication quality assurance were analyzed firstly. The the five-dimensional analysis system based on the coverage, quality, interference, switching and capacity was expounded. Then, the high-speed railway simulation road test algorithm was implemented by means of a soft-hard signaling platform. The cell and user recognition filtering methods, the user positioning and handover point location determination methods were optimized in tile scenario of high-speed railway. The high-speed railway LTE simulation road test and optimization strategy based on soft and hard mining signaling application are developed. Problems of antenna azimuth angle inaccuracy, switching loss, interference and other complicated wireless problems could be found quickly. It effectively reduces the cost of manual road test annd has a very high application value.
