摘要
针对现有算法不能准确估计中、高速UE的移动状态的问题,提出一种优化的移动状态估计算法。该算法考虑了UE穿越小区的方式,并赋予相应的权重,同时提出一种判决门限设定方法。仿真结果表明,相对于现有的算法,该算法对中、高速UE移动状态估计的准确率分别提高了16%和20%,能够较好地解决中、高速UE移动状态估计不准确的问题;门限设定方法简单有效,通用性好,可应用于实际系统中。
Focusing on the problem of existing solution that the mobility state of user equipment（UE） in medium and high speed cannot be accurately estimated,an optimised algorithm for mobility state estimation is proposed,which takes into account the manners of UE in crossing the cells and endows corresponding counting weights.And a new method for threshold setting is presented as well.Simulation results show that the estimation accuracy of mobility state of UE in medium and high speed can be improved by 16% and 20% compared with existing solution respectively,which is able to well resolve the problem of inaccurate estimation of mobility state of UE with medium and high speed,and the threshold setting method is simple and effective with good universality,it is available for application in practical system.
