Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
The present embodiment provides a terminal positioning method, which is suitable for various architectures including a positioning server, such as a networking architecture composed of wired devices such as an AC (Access Controller) and a convergence switch, a GSM (Global System for Mobile Communications ), a CDMA (Code Division Multiple Access), a WCDMA (Wideband Code Division Multiple Access), a GPRS (General Packet Radio Service), an LTE (Long Term Evolution, Long Term Evolution-enhanced) System, an LTE-a (Long Term Evolution-advanced, Long Term Evolution), a UMTS (Universal Mobile Telecommunications System), and the like. The terminal can be a mobile phone, an IPAD and other mobile devices. The execution main body of the embodiment is a terminal positioning device, which may be independently configured or integrated in a positioning server, and the positioning server is configured to position a terminal according to information of the terminal.
Fig. 1 is a schematic flow chart of a terminal positioning method according to this embodiment. The terminal positioning method comprises the following steps:
The terminal may send its own information through the channel, for example, periodically send a Probe-request frame through the channel, which contains any interaction information that may exist between the terminal and other devices, for example, a frame described in protocol IEEE (Institute of electrical and Electronics Engineers) 802.11, and the Probe-request frame carries its own signal strength information, chip information, and so on. In this way, the terminal location device may monitor whether there is frame information sent by the first terminal in the supported channels, where the frame information includes signal strength information, channel information, chip information, and the like of the first terminal. Specifically, the terminal positioning apparatus 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 must periodically send according to the relevant protocol. .
Alternatively, the terminal location means transmits a probe message in the supported channel, which may specifically be a location probe frame, e.g. a data frame. If the terminal location device receives ACK (Acknowledgement) or other type frame defined by the protocol 802.11 returned by the first terminal according to the probe message, the signal strength information, channel information, chip information, etc. of the first terminal can be obtained from the ACK or other type frame. This approach is an "active interrogation" approach, i.e. the terminal location device can actively detect the location of the terminal.
And 102, sending the information of the first terminal to a positioning server so that the positioning server positions 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 the positioning server can obtain the first terminal for positioning through a positioning algorithm after receiving the information of the first terminal. After the position information of the first terminal is acquired, the positioning server can return the position information to the first terminal through the terminal positioning device. The positioning algorithm may specifically be a positioning algorithm based on RSSI (Received Signal Strength Indicator) ranging, and certainly, other positioning algorithms in the prior art may also be adopted according to actual needs, which is not limited in this embodiment.
The above-mentioned mode belongs to an "off-line" mode, i.e. the first terminal does not need to be connected to the terminal positioning device, and the positioning process can be completed.
In the terminal positioning method of this embodiment, the information of the first terminal is obtained by obtaining the information sent by the first terminal in the channel, so that the positioning server positions the first terminal according to the information of the first terminal itself, which can avoid the situation that the Wi-Fi traffic is occupied by the first terminal when the first terminal specially reports the information of the first terminal because the first terminal needs to perform positioning as much as possible, reduce the burden of the first terminal, and the terminal positioning device obtains the real-time information of the first terminal, so that the positioning of the first terminal can be more accurate. In addition, the first terminal can perform positioning without installing positioning software, and the burden of the first terminal is further reduced.
Optionally, there may be a plurality of terminal positioning devices, each terminal positioning device may be registered in the positioning server, the positioning server may generate a network topology map according to registration information of the plurality of terminal positioning devices and a pre-acquired physical space map, the network topology map may describe physical distribution of actual spaces of the terminal positioning devices, the positioning server may position the terminal according to the network topology map, and the network topology map facilitates subsequent service expansion.
Specifically, the position of each terminal positioning device may be planned in advance, so that when the terminal positioning device registers in the positioning server, the terminal positioning device may carry its own position information in the registration information, so that the positioning server learns the position information of each terminal positioning device, and generates a network topology map by combining the physical space map.
Example two
The embodiment provides a terminal positioning method based on the embodiment one.
Optionally, the terminal positioning method of this embodiment further includes:
and when the connection of the second terminal is detected, sending the pre-acquired information of the second terminal to the positioning server so that the positioning server positions the second terminal according to the information of the second terminal.
The second terminal and the first terminal of this embodiment may be the same terminal or different terminals.
The second terminal may be pre-registered with the terminal positioning device, and the terminal positioning device may obtain information of the second terminal to be detected, such as signal strength information, channel information, chip information, and the like, according to the registration information. Therefore, when the terminal positioning device detects that the second terminal is connected to the terminal positioning device, the terminal positioning device can acquire the information of the second terminal and send the information of the second terminal to the positioning server, so that the positioning server can perform positioning according to the information of the second terminal. This situation belongs to the second terminal "on-line" situation, i.e. the situation where the second terminal is connected to the terminal positioning device.
In addition, if the terminal positioning device wants to know the position information of a certain registered terminal and the terminal is in an off-line state, the terminal positioning device can also send detection information to the terminal to acquire the real-time information of the terminal and send the information of the terminal to the positioning server for positioning, so that the terminal positioning device can acquire the position information of the desired terminal in real time.
It can be imagined that when the second terminal leaves the registered terminal positioning device, the other terminal positioning devices may acquire the information of the second terminal by using the method of the first embodiment, and send the information of the second terminal to the positioning server for positioning, which is not described in this embodiment again.
The terminal positioning method of the embodiment not only avoids the situation that the terminal occupies Wi-Fi flow due to the fact that the terminal needs to be positioned and reports the information of the terminal, reduces the burden of the terminal, but also can realize the positioning of an 'online' terminal and an 'offline' terminal at the same time, and is greatly convenient for users.

Step 202, the positioning server generates a network topology map according to the registration information of each terminal positioning device and the pre-acquired physical space map.
The specific obtaining method is the same as that of the first embodiment or the second embodiment, and is not described herein again.
And step 204, the terminal positioning device sends the acquired information of the terminal to be positioned to the positioning server.
Step 205, after receiving the information of the terminal to be positioned, the positioning server positions the terminal.
For example, the positioning server may determine information of the terminal positioning device according to the network topology map, so as to determine the position of the terminal to be positioned. How to position the terminal by the specific positioning server belongs to the prior art, and details are not described in this embodiment.
Step 206, the positioning server sends the positioning information of the terminal to the terminal through the terminal positioning device.
