摘　　要：从基于无线信号的物理建模转到对信号环境与生活行为建模,提出了一种基于综合空间位置索引模型的定位技术和算法。通过基站、Wi-Fi、道路、POI构建综合位置空间索引,并根据人的日常行为分布,对道路和POI设置不同权重,最后通过综合空间位置索引模型计算移动终端位置,从而提高定位结果的合理性和精度。From the physical modeling based on wireless signals to modeling of signal environment and living behavior, a localization algorithm for spatial location index model was presented. Integrated spatial location index model was constructed based on base station,Wi-Fi, road, POI. Different weights on the road and POI according to the distribution of people's daily behavior was set. Finally,the location of the mobile terminal base on integrated spatial location index model was calculated. This method can improve the rationality and accuracy of the positioning results.
