摘　　要：从信号传播的物理建模转变为对信号环境与用户行为的建模,提出了一种基于i Beacon和Wi-Fi的位置空间模型定位技术和算法。通过i Beacon、空间位置及POI构建位置空间模型索引,并根据用户的常态行为特征,对空间位置和POI分别设置不同权重,最后通过位置空间模型索引计算终端的具体位置,显著提高了定位的合理性和精度。Firstly,the physical modeling of signal propagation was transited into the modeling of signal environment and user behavior in this paper.Then,a space model positioning technique and algorithm based on iBeacon and Wi-Fi were presented.The space model index is built by means of iBeacon,space location and POI.Different weights of space location and POI were configured according to user＇s normal behavior characteristics.Finally,the exact location of terminal was calculated according to location space index.The proposed method can effectively improve the feasibility and accuracy of positioning.
