AI Technical Summary

Problems solved by technology

When the terminal is connected to the WiFi network, the terminal will stop sending Probe Request. At this time, the surrounding APs will not be able to measure the signal of the terminal, thus losing the ability to locate the user terminal.

Embodiment Construction

[0025] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.

[0026] Considering that under the iOS7 platform, because Apple shields the API for the application program to obtain the surrounding WiFi network scanning results on the iOS7 platform, the positioning terminal application based on the surrounding WiFi signal measurement on the iphone terminal is invalid. Based on this, the embodiment of the present invention A method, device and system for positioning a user terminal are provided.

[0027] see figure 1 The flow chart of the method for locating a user terminal based on the description on the user side is shown. This method can be applied to various user terminal devices of Apple Inc., such as Iphone4 / 5 / 5S and other mobile phones. It includes the following steps:

[0028] Step S102, after the user terminal accesses the WiFi network through an access point (ie AP), ...

Abstract

The invention provides a method, device and system for positioning a user terminal. The method comprises the steps that the user terminal establishes connection with a WiFi positioning server after making access to a WiFi network through access points, the user terminal sends positioning request messages carrying positioning identifiers to the access points to enable the access points to carry out logout operation on the user terminal, the user terminal sends detection request messages in all channels after logout to enable surrounding access points to collect the positioning information of the user terminal for the WiFi positioning server to carry out positioning on the user terminal, and the user terminal makes access to the WiFi network again to obtain the position of the user terminal from the WiFi positioning server. The method, device and system for positioning the user terminal solve the problem that when the terminal makes access to the WiFi network, due to the fact that the terminal stops sending the detection request messages, the access points cannot carry out signal measurement on the terminal, and the terminal cannot be positioned.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method, device and system 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 advertisement push, navigation, etc. At present, technologies mainly used for positioning include: satellite positioning technology, cellular technology, RFID (Radio Frequency Identification, radio frequency identification) technology and WiFi technology; among them, RFID and WiFi (Wireless Fidelity, wireless fidelity) technology are mainly used indoors. [0003] In the related art, there is a WiFi positioning technology based on RSSI (Received Signal Strength Indication, received signal strength indication). This technolo...
