Problems solved by technology

Indoor positioning technology is difficult to penetrate walls due to satellite signals, complex indoor wireless environment, and serious multipath fading of wireless signals. As a result, traditional GPS technology and positioning technology based on cellular networks are not applicable, and the development has been relatively slow.

Abstract

The embodiment of the invention discloses an indoor positioning method and device. The indoor positioning method comprises the following steps: acquiring communication data reported by a terminal; andperforming indoor positioning on the terminal according to the grids of the building, the first corresponding relationship between the main neighbor cell combination and the fingerprint information and the communication data. According to the embodiment of the invention, indoor positioning is performed on the terminal based on the communication data and the first corresponding relationship, and indoor positioning of the terminal is realized based on the communication data.

Description

technical field [0001] Embodiments of the present invention relate to but are not limited to the field of location services, especially an indoor positioning method and device. Background technique [0002] At present, operators have developed wireless networks with wide coverage. How to use the data generated by the existing network to provide guidance for network development, to help operators mine greater value from big data, and to maximize network value is crucial for operators. important work. [0003] Operators began to collect various data in the communication network, established a big data analysis platform, and expanded the application of data in new fields. The data in the mobile communication network has a wide range of uses in advertising, public security, personal finance, etc., and the location information of the communication data is the core basis of the upper application scenarios and services. Therefore, accurate location service based on communication ...
