Problems solved by technology

[0003] In practical applications, the above positioning technologies have certain limitations: GPS positioning and GSM positioning are only suitable for outdoors; Bluetooth positioning and RFID detection range are small; ultrasonic and infrared methods are easily blocked by media
[0004] In the related art, there is a WiFi collaborative indoor positioning technology. The disadvantage of this technology is that the signal is interfered by factors such as refraction, reflection, and diffraction during propagation, resulting in a large positioning error (the error can usually reach tens of meters), which is difficult to locate. Meet the user's requirements for positioning accuracy

Embodiment Construction

[0018] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.

[0019] Considering the problem of relatively large positioning errors in the WiFi collaborative indoor positioning technology, based on this, embodiments of the present invention provide a method and device for positioning a user terminal.

[0020] In order to realize the present invention, this embodiment arranges positioning devices (location points) that assume different roles (roles) indoors, including single point positioning devices, area positioning devices and auxiliary positioning devices. Among them, single-point positioning devices are widely arranged indoors, and the position of each single-point positioning device is represented by coordinates; regional positioning devices are arranged in different areas (such as floors, partitions), and the coordinates of regional positioning devices represent this are...

Abstract

The invention provides a method and device for positioning a user terminal. The method includes the steps that the position value of one set of single-point positioning equipment within a preset distance is obtained through the user terminal, or the position values of multiple sets of single-point positioning equipment beyond the preset distance are obtained through the user terminal; the user terminal is positioned by itself according to the obtained position value of the single-point positioning equipment. The device comprises an obtaining module and a positioning module. The obtaining module is used for obtaining the position value of one set of single-point positioning equipment within the preset distance or the position values of the sets of single-point positioning equipment beyond the preset distance. The positioning module is used for positioning the user terminal according to the position values of the single-point positioning equipment. The problem that a WiFi cooperative positioning technology is large in positioning error is solved, the requirement for positioning precision of a user is met, and the user terminal is accurately positioned.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for positioning a user terminal. Background technique [0002] At present, LBS (Location-Based Service, based on geographic location service) has become a hot spot in the market, and various service providers have successively launched more optimized and appropriate services based on user location information, including fixed-point advertising push, navigation, etc. At present, the technologies mainly used for positioning include: satellite positioning technology (GPS positioning), cellular technology (GSM positioning), RFID (Radio Frequency Identification, radio frequency identification) technology, WiFi technology, infrared positioning technology, ultrasonic positioning technology and Bluetooth positioning technology. Among them, RFID and WiFi (Wireless Fidelity, wireless fidelity) technologies are mainly applied indoors. [0003] In practical applicatio...
