Embodiment 1

[0055] In the embodiment of the present invention, in order to solve the problem that the indoor positioning method for the user using RFID technology in the prior art results in high cost of indoor positioning and low positioning accuracy, the embodiment of the present invention provides an indoor The method of positioning, the implementation of this method needs to be based on the indoor communication network.

[0056] Specifically, in order to enable the internal communication network signal of a large building to cover the entire building, communication operators will deploy indoor distribution systems in the building (such as figure 1 shown), the indoor distribution system consists of signal sources, combiners, power splitters, feeders and antenna points.

[0057] Since a combiner is added to the indoor distribution system, the indoor distribution system can bear different network signals. For example, the indoor distribution system can simultaneously carry network signal...

Abstract

The embodiment of the invention provides an indoor positioning method, system and apparatus. The method comprises: determining the deviation value between the signal intensity of a first network signal, and the signal intensity of a second network signal through obtaining the signal intensity of a first network signal, and the signal intensity of a second network received by a user terminal at an antenna point; matching the obtained deviation value with fixed deviation values in a first preset list keeping corresponding relations between fixed deviation values and antenna points; and when the deviation value corresponding to the user terminal matches a deviation value in the first preset list, setting the position information of the antenna point corresponding to the matched fixed deviation value as the position information of the user terminal. Accordingly, the indoor positioning method, system and apparatus reduce the cost of positioning the user terminal indoors, and improve the accuracy of positioning the terminal indoors in a certain degree.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an indoor positioning method, system and device. Background technique [0002] The current outdoor positioning technology mainly uses satellite positioning systems, such as the Beidou positioning system, and mobile base station assisted positioning. Its positioning must rely on the time difference of arrival of multiple satellite signals or radio frequency signals of multiple base stations for positioning calculations, but outdoor positioning technology cannot play its role in indoor environments because satellite signals cannot be received. [0003] In order to achieve indoor positioning, radio frequency identification technology (English: Radio Frequency Identification for short: RFID) is introduced, that is, by deploying multiple positioning signal sources or positioning signal tags indoors, the intensity or time delay similar to outdoor positioning is used. Th...
