Problems solved by technology

However, this method is also difficult to implement in practice, because the channels of non-associated terminals are not fixed, and the time in one channel may be relatively short, and the above-mentioned server scheduling process will take a long time, for example, the server cannot respond in time, and waits for server instructions When arriving at the AP, the terminal may have left the AP, causing the AP to fail to perform positioning measurement
This lack of support for non-associated terminal positioning cannot meet the market's demand for non-associated terminal positioning

Embodiment Construction

[0019] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present application as recited in the appended claims.

[0020] The present application provides a terminal positioning measurement method, which is used for positioning non-associated terminals by using an RTT-based positioning measurement manner. Such as figure 1 As shown, the scenario of terminal positioning is exemplified, and multiple APs (Access Points, wireless access devices) may be included in the RTT positioning network, for example...

Abstract

The application provides a terminal positioning and measurement method and a wireless access device. The method comprises: when an inquiring request message sent by a terminal is received, whether the terminal is a non-associated terminal is determined according to terminal state information stored into an access controller AC; and if so, RTT positioning and measurement are carried out on the terminal and a measurement result is sent to a server, so that the server can localize the terminal based on the measurement result. Therefore, positioning of a non-associated terminal based on RTT is realized.

Description

technical field [0001] The present application relates to communication technology, in particular to a terminal positioning measurement method and wireless access equipment. Background technique [0002] With the application of mobile Internet and big data, WLAN-based positioning technology has broad application prospects in many industries. One of the WLAN positioning technologies includes: an RTT (Round Trip Time, round-trip time) measurement and positioning method. However, the current RTT positioning uses an active measurement method, that is, the AP actively sends a measurement request message to the terminal to be positioned, receives the measurement response fed back by the terminal, and calculates the round-trip time. This active measurement method only supports the positioning of associated terminals. For non-associated terminals, the RTT method is difficult to support the positioning of non-associated terminals because the working channel of non-associated termina...
