Summary:The invention relates to a base station positioning method based on probability fingerprints. Probability fingerprints and pseudo probability fingerprints are generated by the adoption of a continuous signal sampling mode and a corresponding probability statistic method, the defect that a traditional sampling and matching positioning method can be disturbed by signal intensity fluctuation easily is overcome through probability similarity matching, and the accuracy for positioning by using a plurality of base station signals is improved. According to the base station positioning method based on the probability fingerprints, the signal strength probability statistic information of a plurality of adjacent base stations is fully utilized, positioning accuracy is improved, there is no need for extra devices to be additionally arranged on terminal equipment, and therefore precise indoor positioning application can be easier achieved on general public consumption type mobile phone terminals.
