Abstract

The invention is suitable for the technical field of communication and discloses an indoor positioning method, device and system for a terminal. The method comprises the following steps of: enabling a near-end machine of an indoor distribution system to issue a pseudo-carrier to a polled far-end machine according to a polling routing table which is established in advance so as to enable the far-end machine to issue the pseudo-carrier to the terminal; receiving a measurement report of the terminal, which is returned by the far-end machine; and determining the position of the terminal according to the measurement report. Information of the pseudo-carrier is contained in the measurement report of the terminal, and the position of the terminal can be determined by judging the far-end machine where the terminal is located. Correspondingly, the invention provides the corresponding indoor positioning device and system. According to the technical scheme provided by the invention, the problems of high cost and complex scheme in the existing positioning technology can be solved, the cost can be reduced, and the simpler indoor precise positioning can be realized.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to an indoor positioning method, device and system. Background technique [0002] Currently, terminal (for example, wireless terminals, such as mobile phones, etc.) positioning technologies continue to develop. Wireless terminal positioning refers to obtaining the location information (latitude and longitude coordinates) of mobile phones or terminal users through specific positioning technology, and marking the position of the positioned object on the electronic map. [0003] Currently, there are generally two positioning technologies, one is positioning based on a Global Positioning System (GPS, Global Positioning System), and the other is positioning based on a base station (BS, Base Station) in a mobile communication network. In the mobile communication network, the positioning based on the base station includes: the positioning technology based on the cell ide...
