Fig. 1A is a schematic diagram of a system architecture to which a positioning method or apparatus according to an embodiment of the present invention can be applied. As shown in fig. 1A, the system architecture 100 may include a terminal device 101, networks 102, 104, a server 103, and a location tracker 105. The network 102 or 104 is the medium used to provide the communication link between the terminal device 101, the server 103 and the location tracker 105. Networks 102 or 104 may include various types of connections, such as wire, wireless communication links, or fiber optic cables, to name a few. It should be understood that the number of terminal devices, networks, and servers in FIG. 1A are merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation. For example, the server 102 may be a server cluster composed of a plurality of servers, and the like.
The terminal device 101 receives the positioning information of the positioning tracker 105 through the server 103. The terminal device 101 may be various electronic devices having a display screen, including but not limited to a smart phone, a tablet computer, a portable computer, a desktop computer, and the like.

Referring to fig. 2, fig. 2 is a schematic flowchart of a positioning method according to an embodiment of the present invention, where the method includes:
s201, the terminal acquires the position information of the positioning tracker through a cellular data network.
The positioning method provided by the embodiment of the invention is applied to the terminal. The terminal sends a location acquisition request to a location server through a cellular data network. And the terminal receives a position acquisition response sent by the positioning server in response to the position acquisition request. Wherein the location acquisition response carries location information of the location tracker. Specifically, the terminal sends a location acquisition request to the location server through the cellular data network, wherein the location acquisition request includes an identifier of the terminal and an identifier of the location tracker. The server can judge whether the terminal has the corresponding position request authority or not based on the identifier of the terminal and the identifier of the positioning tracker contained in the request. And if the terminal has the corresponding position request authority, the server forwards the position acquisition request to the corresponding positioning tracker. The positioning tracker forwards the position information of the positioning tracker to the server. The server sends a location acquisition response to the terminal. And if the terminal does not have the corresponding position request authority, the server returns prompt information to the terminal.
The terminal may also send a location acquisition request directly to the location tracker over the cellular data network. The positioning tracker can verify the authority of the terminal and send the position acquisition response carrying the position information of the positioning tracker to the terminal with the access authority.
The location information may be represented in longitude and latitude coordinates. A known position may be used as a reference point, and the position information may be expressed by a distance from the reference point and a position at the reference point, for example: the position information may be expressed in 100 meters and true west with a flagpole on a certain playground as a reference point. The position information indicates a position of the position exactly 100 meters west from the reference point. Those skilled in the art may also use other ways to represent location information and the application is not so limited.
S202, the terminal determines the distance between the positioning tracker and the terminal according to the position information of the positioning tracker and the position information of the terminal.
The terminal can obtain the position information of the terminal through a positioning device of the terminal. The terminal can also obtain the position information of the terminal through some positioning software, such as Beidou navigation and the like. Those skilled in the art may also adopt other manners as long as the position information of the terminal can be obtained, which is not described herein again.
The distance between the positioning tracker and the terminal can be directly calculated according to the position information of the positioning tracker and the position information of the terminal. The distance between the positioning tracker and the terminal can also be determined by software such as an electronic map. In short, the distance between the location tracker and the terminal may be determined according to the location information of the location tracker and the location information of the terminal, and the present application is not limited to this.
S203, when the distance is smaller than the preset distance, the terminal sends a Bluetooth connection establishment request to the positioning tracker.
The preset distance may be set according to bluetooth performance characteristics of the terminal and bluetooth performance characteristics of the location tracker. For example, in the case where the terminal and the location tracker both support bluetooth 5.0 communication, the terminal can perform high-quality communication within a range of 500 meters by using bluetooth 5.0 communication. The positioning tracker can communicate with high quality in a communication mode of Bluetooth 5.0 within the range of 300 meters. Then, the preset distance may be set to 300 meters to ensure that the terminal and the location tracker may communicate with each other in a bluetooth manner with higher quality within the preset distance range.
Optionally, the terminal sends a bluetooth connection establishment request to the location tracker at a predetermined time period. The terminal sends a bluetooth connection request only once and may not be able to successfully establish a bluetooth connection with the location tracker. And the terminal sends a Bluetooth connection establishment request to the positioning tracker in a period of preset time, so that the probability of successfully establishing the Bluetooth connection between the terminal and the positioning tracker can be increased.
S204, after the terminal is successfully connected with the positioning tracker through Bluetooth, the cellular data network is disconnected, a position acquisition request for acquiring the position information of the positioning tracker is sent to the positioning tracker through the Bluetooth connection, and the position information of the positioning tracker is acquired through the Bluetooth connection.
Optionally, after step S204, the method further includes:
and when detecting that the communication quality parameters of the Bluetooth connection do not meet the preset conditions, disconnecting the Bluetooth connection.
Obtaining location information for the location tracker over the cellular data network.
Optionally, the communication quality parameter includes one or more of a time delay and a packet loss rate.
The preset conditions can be set according to actual requirements. If the communication quality parameter of the Bluetooth connection does not meet the preset condition, the communication quality between the terminal and the positioning tracker is poor. If the two continue to communicate in a bluetooth connection, there is a risk of data loss or poor communication quality. Thus, the bluetooth connection is disconnected. Obtaining location information for the location tracker over the cellular data network. To ensure a higher quality of communication between the terminal and the position tracker.
According to the positioning method provided by the embodiment of the invention, when the distance between the terminal equipment and the positioning tracker is smaller than the preset distance, the terminal equipment acquires the position information of the positioning tracker through Bluetooth connection. The prior art location tracker has been sending data over the cellular data network. When the positioning tracker transmits data through the cellular data network, the positioning tracker consumes a relatively high power and is relatively power-consuming. Therefore, the invention can solve the problems of higher use power and shorter endurance time of the positioning tracker in the prior art.

The positioning method provided by the embodiment of the invention can still keep a high-quality communication state between the terminal and the positioning tracker when the distance between the terminal and the positioning tracker changes or the Bluetooth connection is not successfully established.
Referring to fig. 4, fig. 4 is a schematic flowchart of another positioning method provided in an embodiment of the present invention, where the method includes:
s401, receiving a Bluetooth connection request from a terminal.
The positioning method provided by the embodiment of the invention is applied to a positioning tracker end.
Optionally, the bluetooth connection request carries a device identifier of the terminal.

and judging whether the equipment identifier is the same as a pre-stored equipment identifier.
If so, verifying that the Bluetooth connection request passes.
If not, verifying that the Bluetooth connection request does not pass.

According to the positioning method provided by the embodiment of the invention, when the distance between the terminal equipment and the positioning tracker is smaller than the preset distance, the positioning tracker is obtained and the position information of the positioning tracker is sent to the terminal equipment through Bluetooth connection. The prior art location tracker has been sending data over the cellular data network. When the positioning tracker transmits data through the cellular data network, the positioning tracker consumes a relatively high power and is relatively power-consuming. Therefore, the invention can effectively reduce the use power of the positioning tracker and prolong the endurance time of the positioning tracker.
