Embodiment one

This embodiment provides a terminal positioning method, which is applicable to various architectures including a positioning server, such as a network architecture composed of AC (Access Controller, Access Controller) and wired devices such as convergence switches, GSM (Global System for Mobile Communications, Global System for Mobile Communications), CDMA (Code Division Multiple Access, Code Division Multiple Access), WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access)), GPRS (General Packet Radio Service, General Packet Radio Service ), LTE (Long Term Evolution, long-term evolution-enhanced) system, LTE-A (Long Term Evolution-Advance, long-term evolution), UMTS (Universal Mobile Telecommunications System, universal mobile communication system), etc. The terminal can be a mobile device such as a mobile phone or an IPAD. The execution subject of this embodiment is a terminal positioning device, which can be set independently or integrated in a positioning server, and the positioning server is used to locate the terminal according to the information of the terminal.

As shown in FIG. 1 , it is a schematic flowchart of a terminal positioning method according to this embodiment. The terminal positioning method includes:

Step 101, acquire information of a first terminal by monitoring supported channels.

The terminal will send its own information through the channel, such as periodically sending Probe-request frames through the channel, including any interaction information that may exist between the terminal and other devices, such as the protocol IEEE (Institute of Electrical and Electronics Engineers, Institute of Electrical and Electronics Engineers) The frame described in 802.11, the Probe-request frame carries the terminal's own signal strength information, chip information, and so on. In this way, the terminal positioning 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, etc. of the first terminal. Specifically, the terminal positioning device can monitor whether there is frame information sent by the first terminal in the supported channel, and the frame information is sent periodically by the first terminal, that is, the frame information that the first terminal must periodically send according to the relevant protocol . .

Alternatively, the terminal positioning device sends a detection message in a supported channel, and the detection message may specifically be a positioning detection frame, such as a data frame. If the terminal positioning device receives the ACK (Acknowledgment, confirmation character) returned by the first terminal according to the detection message or other types of frames defined by the protocol 802.11, it can obtain the signal strength information, channel information, chip information, etc. of the first terminal from it . This method belongs to the "active inquiry" method, that is, the terminal positioning device can actively detect the location of the terminal.

Step 102, sending the information of the first terminal to the positioning server, so that the positioning server can locate the first terminal according to the information of the first terminal.

The terminal positioning device sends the monitored information of the first terminal to the positioning server, and after receiving the information of the first terminal, the positioning server can use a positioning algorithm to locate the first terminal. After acquiring the location information of the first terminal, the positioning server may return the location information to the first terminal through the terminal positioning device. Specifically, the positioning algorithm may be a positioning algorithm based on RSSI (Received Signal Strength Indicator, received signal strength display), and of course other positioning algorithms in the prior art may also be used according to actual needs, which are not limited in this embodiment.

The above method belongs to the "offline" method, that is, the first terminal can complete the positioning process without being connected to the terminal positioning device.

Specifically, the location of each terminal positioning device can be pre-planned. In this way, when the terminal positioning device registers with the positioning server, it can carry its own position information in the registration information, so that the positioning server can know the location information of each terminal positioning device. The location information of the network is combined with the physical space map to generate a network topology map.

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 positioning device detects that the second terminal is connected to itself, it can obtain the information of the second terminal and send the information of the second terminal to the positioning server, so that the positioning server can use the information of the second terminal to locate. This situation belongs to the situation that the second terminal is "online", that is, the situation that the second terminal is connected to the terminal positioning device.

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

It is conceivable that when the second terminal leaves the registered terminal locating device, other terminal locating devices can obtain the information of the second terminal in the manner of Embodiment 1, and send the information of the second terminal to The positioning server performs positioning, which will not be described in detail in this embodiment.

The terminal positioning method of this embodiment not only avoids the situation that the terminal deliberately reports its own information to occupy Wi-Fi traffic due to the need for positioning, reduces the burden on the terminal, but also realizes the "online" terminal and "offline" terminal at the same time. Positioning greatly facilitates users.
