FIG. 1 is a schematic flowchart diagram of a terminal positioning method according to this embodiment. The terminal positioning method includes:

Step 101: Acquire information of the first terminal by monitoring the supported channel.

The terminal transmits its own information through the channel, for example, periodically sends a Probe-request frame through the channel, and the packet There may be any interaction type information between the terminal and other devices, for example, a frame described by IEEE (Institute of Electrical and Electronics Engineers) 802.11, which carries the signal strength information of the terminal itself, Chip information and more. In this way, the terminal locating device can monitor whether there is frame information sent by the first terminal in the supported channel, and the frame information includes signal strength information, channel information, chip information, and the like of the first terminal. Specifically, the terminal locating device may monitor whether there is frame information sent by the first terminal in the supported channel, where the frame information is periodically sent by the first terminal, that is, the frame information that the first terminal needs to periodically send according to the relevant protocol. . .

Alternatively, the terminal locating device sends a probe message in the supported channel, and the probe message may specifically be a location probe frame, such as a data frame. If the terminal locating device receives the ACK (Acknowledgement) returned by the first terminal or other types of frames defined by the protocol 802.11, the signal strength information, channel information, chip information, etc. of the first terminal may be obtained therefrom. . This method belongs to the “active inquiry” mode, that is, the terminal positioning device can actively detect the location of the terminal.

The second terminal may be pre-registered with the terminal locating device, and the terminal locating device may obtain information about the second terminal, such as signal strength information, channel information, chip information, and the like, according to the registration information. In this way, when the terminal locating device detects that the second terminal is connected to itself, it can obtain the information of the second terminal according to the information of the second terminal, and send the information of the second terminal to the positioning server, so that the positioning server can obtain the information according to the second terminal. Positioning. This case belongs to the case where the second terminal is "online", that is, the case where the second terminal is connected to the terminal locating device.

In addition, if the terminal locating device wants to know the location information of a certain registered terminal and the terminal is in an "offline" state, it may also send the probe information to the terminal to obtain real-time information of the terminal, and the terminal is The information is sent to the positioning server for positioning, so that the terminal positioning device can obtain the location information of the desired terminal in real time.

It is conceivable that when the second terminal leaves the registered terminal locating device, the information of the second terminal can be obtained by the other terminal locating device in the manner of the first embodiment, and the information of the second terminal is sent to The positioning server performs positioning, which is not described in this embodiment.

The method for locating the terminal in this embodiment not only avoids the situation that the terminal intentionally reports that its information occupies Wi-Fi traffic due to the need for positioning, reduces the burden on the terminal, and can simultaneously implement the "online" terminal and the "offline" terminal. Positioning is greatly convenient for users.
