Abstract

The invention discloses a fingerprint locating method and server. A located coverage area is previously divided into a plurality of sub areas according to an architectural pattern, and fingerprint databases are established according to fingerprint information of known reference points of the sub areas on the situation of various visitor flow rates. In an actual locating process, the matched fingerprint database is firstly determined, current fingerprint information is compared with the fingerprint information in the determined fingerprint database, a plurality of reference points with the most similar fingerprint information are chosen, the positions of the chosen reference points are weighted and averaged to serve as the current position of a terminal, and location is finished. The rich fingerprint databases are established according to the architectural pattern and the visitor flow rates, and the matched fingerprint database is chosen in a targeted mode to be compared, so that the effects of buildings and the visitor flow density are eliminated. Thus, the accuracy of the fingerprint location is improved, and the environmental adaptability is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication positioning, in particular to a fingerprint positioning method and a server. Background technique [0002] With the development of communication technology, as a part of mobile communication and personal communication service, location service becomes more and more important. [0003] Fingerprint positioning technology is a commonly used technology in indoor location services. The traditional fingerprint positioning technology calculates the position of the terminal according to the power of the received signal. [0004] In the process of research and practice, it is found that due to changes in crowds and obstacles, the power of the signal will be greatly affected, and it is difficult to guarantee the accuracy of the positioning results obtained by positioning based on the power. Contents of the invention [0005] Based on the above situation, the present invention proposes a fing...
