Multimode signal-based positioning method, system and positioning platform

Abstract

The embodiment of the invention discloses a multimode signal-based positioning method, a system and a positioning platform. The method comprises the following steps: the positioning platform receives an uplink message sent by a terminal to be positioned after the terminal to be positioned acquires multimode signals at a located position, wherein the multimode signals comprise WiFi (Wireless Fidelity) signals and mobile communication network signals, the uplink message comprises information of the multimode signals, i.e. types and parameters of the multimode signals acquired by the terminal to be positioned, the types of the multimode signals comprise the WiFi signals or the mobile communication network signals, and the corresponding parameters of the multimode signals comprise WiFi parameters and the base station parameters of a mobile communication network; and the positioning platform acquires an indoor position coordinate of a building corresponding to a standard characteristic fingerprint which is matched with the information of the multimode signals, and takes the indoor position coordinate of the building as an indoors positioned result of the terminal to be positioned. The multimode signal-based positioning method, the system and the positioning platform disclosed by the embodiment of the invention can enhance the indoors positioning accuracy and save the cost required by indoors positioning.

Description

technical field [0001] The invention relates to communication technology, in particular to a multi-mode signal-based positioning method and system, and a positioning platform. Background technique [0002] With the development of wireless communication technology and network technology, the use of mobile terminals has gradually become popular, and has become one of the necessary daily necessities carried by the public. With the increase of mobile terminal functions, people can complete more and more work through mobile terminals. For example, positioning technology can be applied to mobile terminals, and mobile terminals can be configured for enterprise personnel, such as patrol field personnel, sales field personnel, etc. To realize the location management of enterprise personnel. [0003] Mobile terminal positioning is divided into active positioning and third-party positioning. Wherein, during active positioning, when the mobile terminal user wishes to obtain his curren...

Problems solved by technology

[0006] In the process of realizing the present invention, the inventors found that the prior art indoor positioning method has at least the following problems: when the simple indoor extension of outdoor positioning is used to realize the positioning of the mobile terminal, the positioning accuracy of the indoor position is low, Usually, the positioning accuracy is much lower than outdoor positioning, and the positioning results are inaccurate; when indoor positioning is performed by deploying positioning sensors, the cost is high because of the need for special positioning sensors, especially when the positioning accuracy needs to be improved, it is necessary to deploy positioning with a higher density sensors, further increasing the cost of positioning
