Fig. 4 is a flowchart illustrating a positioning method according to an exemplary embodiment, where as shown in fig. 4, the interaction subjects of the method are a route forwarding device and a terminal, and the method includes the following steps:
in step 401, the route forwarding device scans an identifier and a corresponding route signal strength of at least one route forwarding device within a current WIFI scanning range.
The route forwarding device may be a router, a switch, or other devices capable of implementing the route forwarding function. In one embodiment, the route forwarding device may be a battery-powered route forwarding device that may be moved during operation. The identifier of each of the at least one route forwarding device is used to uniquely indicate the route forwarding device, and may be a factory serial number, a Media Access Control (MAC) address, and the like of the corresponding route forwarding device, which is not limited in this disclosure.
The route signal strength refers to the strength of the detected broadcast signal of the corresponding route forwarding device, and may indicate the distance between the route forwarding device and the scanned corresponding route forwarding device. Moreover, the stronger the corresponding route signal strength is, the closer the distance between the route forwarding device and the scanned corresponding route forwarding device is; the weaker the corresponding route signal strength is, the farther the distance between the route forwarding device and the scanned corresponding route forwarding device is.
In the embodiment of the disclosure, the route forwarding device may initiate WIFI scanning to acquire scanning information, that is, the identifier of at least one route forwarding device within the current WIFI scanning range and the corresponding route signal strength are sent to the terminal, so that the terminal can perform positioning.
Further, in order to reduce the power consumption and processing burden of the route forwarding device, the route forwarding device may scan the identifier of at least one route forwarding device and the corresponding route signal strength within the current WIFI scanning range at intervals of a preset duration. The preset duration may be set by default by the terminal or by a user, which is not limited in the embodiment of the present disclosure. For example, the preset duration may be 10s, that is, the route forwarding device may initiate a WIFI scan every 10s, and scan an identifier and corresponding route signal strength of at least one route forwarding device within a current WIFI scan range.
Further, it is considered that the routing forwarding device initiates the WIFI scanning to broadcast the acquired scanning information to the terminal, but when no terminal is within the broadcast range of the routing forwarding device, the scanning information acquired by the routing forwarding device will not be necessary. Therefore, in order to avoid unnecessary power consumption of the route forwarding device, the manner of initiating the WIFI scan by the route forwarding device may further include: after detecting that connection with at least one terminal is established, scanning the identification of at least one route forwarding device and the corresponding route signal strength in the current WIFI scanning range.
The route forwarding device may establish a connection with the at least one terminal through a wired network or a wireless network, for example, the connection may be made through WIFI.
When detecting that connection with at least one terminal is established, the routing forwarding device can send the acquired scanning information to the at least one terminal, and therefore the scanning information acquired by WIFI scanning can be initiated at the moment. And when the connection with any terminal is not established, WIFI scanning can not be initiated, so that the power consumption is saved.
In step 402, the route forwarding device broadcasts a data packet, where the data packet carries the identifier of the at least one route forwarding device and the corresponding route signal strength.
In practical application, the route forwarding device may broadcast the data packet in a designated frame, for example, the designated frame may be a Beacon (Beacon) frame, and certainly, the designated frame may also have other frame structures, which is not limited in this disclosure.
It should be noted that, after detecting that the connection has been established with the at least one terminal, the route forwarding device may also send the data packet only to the at least one terminal with which the connection has been established. That is, the route forwarding device may only send the data packet to the connected terminal, but not send the data packet to the unconnected terminal, so that the power consumption of the route forwarding device may be further saved, and the accuracy of sending the data packet is improved.
When sending the data packet to the at least one terminal, the route forwarding device may send the data packet through a wired network or a wireless network, which is not limited in this disclosure. For example, when the routing forwarding device is connected to the at least one terminal through WIFI, the data packet may be sent to the at least one terminal through WIFI.
In step 403, the terminal receives the data packet broadcast by the route forwarding device.
It should be noted that a terminal capable of receiving the data packet broadcast by the route forwarding device needs to be in the broadcast range of the route forwarding device, and a terminal that is not in the broadcast range of the route forwarding device cannot receive the data packet broadcast by the route forwarding device.
Further, the terminal may receive the data packet broadcast by the routing forwarding device without initiating the WIFI scan, so as to save power consumption of the terminal. In practical application, the terminal can receive the data message broadcast by the routing forwarding device under the condition that the WIFI scanning is not initiated by starting the function of prohibiting the initiation of the WIFI scanning.
And the function of forbidding the initiation of the WIFI scanning is used for forbidding the terminal to initiate the WIFI scanning. Moreover, when the function of prohibiting initiating the WIFI scanning is started, the terminal may prohibit all operations of initiating the WIFI scanning, or may prohibit only a part of operations of initiating the WIFI scanning, which is not limited in the embodiments of the present disclosure.
For example, when the function of prohibiting the WIFI scanning from being initiated is started, the terminal may prohibit only the WIFI scanning initiated by the currently installed application when the terminal location is acquired, but not prohibit the WIFI scanning initiated by other means. Therefore, when a user controls the terminal to initiate WIFI scanning through the setting interface, the terminal can still execute a scanning task according to the operation of the user, and the user experience is improved.
Further, when the terminal has started the WIFI scanning, after establishing a connection with the route forwarding device, the terminal may also be prohibited from initiating the WIFI scanning.
For example, the terminal may automatically start a function of prohibiting WIFI scanning from being initiated after detecting that a connection is established with the route forwarding device, so that the terminal may prohibit WIFI scanning from being initiated. And when the connection with the route forwarding device is not established, the function of forbidding to initiate the WIFI scanning is not started, and the WIFI scanning is still performed according to the default scanning frequency, so that the positioning is realized.
When the terminal is connected with the route forwarding equipment, the terminal can realize positioning by receiving the data message of the route forwarding equipment, so that the terminal can be prohibited from initiating WIFI scanning to reduce the electric quantity consumption of the terminal; when the connection with the route forwarding device is not established, the terminal may not be able to receive the data packet to the route forwarding device, and in order to avoid influencing positioning, the terminal may not prohibit initiating the WIFI scanning, and still perform the WIFI scanning according to the default scanning frequency.
Therefore, the terminal can be flexibly switched between the power consumption mode and the power saving mode, so that the power consumption can be saved to the maximum extent on the premise of not influencing the positioning, and the performance of WIFI scanning is protected.
Further, the terminal may further provide a scan prohibition option, where the scan prohibition option is used to prohibit the terminal from initiating the WIFI scan. For example, the terminal may start a function of prohibiting WIFI scanning from being initiated when a selection operation of a scan prohibition option is detected.
The scanning prohibition option is used for prohibiting initiating WIFI scanning, and the scanning prohibition option may be a button, a control, an icon, or an entity button. Accordingly, the operation of selecting the scan prohibition option may be an operation of clicking or pressing the scan prohibition option, and the like, which is not limited in this disclosure.
In a possible implementation manner, the terminal may further provide a function setting interface, where the function setting interface includes a scan prohibition option. When a user wants to forbid the terminal from initiating the WIFI scanning, the user can call the function setting interface, click the scanning forbidding option and trigger the selection operation of the scanning forbidding option, and then the terminal can forbid the terminal from initiating the WIFI scanning.
Therefore, the terminal can start the function of forbidding to initiate WIFI scanning according to the intention of the user, so that the accuracy of function starting is improved, and the user experience is improved.
In step 404, the terminal uses the data packet to perform positioning to obtain location information.
That is, the terminal may perform positioning by using the identifier of the at least one route forwarding device carried in the data packet and the corresponding route signal strength to obtain the location information.
The process of the terminal positioning by using the data packet to obtain the location information may include: sending a positioning request to a server, wherein the positioning request carries the identifier of the at least one routing forwarding device and the corresponding routing signal strength, and is used for requesting the server to determine the position information according to the identifier of the at least one routing forwarding device and the corresponding routing signal strength; and receiving the position information returned by the server.
The server may pre-store the identifiers of the multiple route forwarding devices and the corresponding location information, so that when the server receives a positioning request sent by the terminal, the server may search for the location information corresponding to the identifier of the at least one route forwarding device according to the identifier of the at least one route forwarding device carried in the positioning request, analyze and determine one location information in combination with the corresponding route signal strength, and return the location information to the terminal.
It should be noted that the interaction process between the routing forwarding device and the terminal may be implemented by modifying a standard WIFI protocol, so that the routing forwarding device may initiate WIFI scanning and broadcast a data packet according to the modified WIFI protocol, and the terminal may receive the data packet broadcast by the routing forwarding device for positioning.
Another point to be noted is that, positioning is performed according to the scanning information acquired by the route forwarding device, and the positioned information is usually the location information of the route forwarding device, but when the terminal can receive the data packet broadcast by the route forwarding device, the terminal is usually located near the route forwarding device, and the distance from the route forwarding device is not too far, so that the location information of the route forwarding device is determined as the location information of the terminal, and the location error is within a reasonable location error range, which can meet the location requirement of the user. That is, the terminal may receive the location information returned by the server, and determine the location information as the actual location information of the terminal.
In addition, in order to improve the positioning accuracy, the terminal can further determine the message signal strength of the data message; and determining the actual position information of the terminal by using the position information and the message signal strength.
For example, the terminal may determine the message signal strength of the data message when receiving the data message; sending a positioning request to a server, wherein the positioning request carries the identifier of the at least one routing forwarding device and the corresponding routing signal strength, and is used for requesting the server to determine the position information according to the identifier of the at least one routing forwarding device and the corresponding routing signal strength; receiving the position information returned by the server; and determining the actual position information of the terminal by using the position information and the message signal strength.
The location information is used to indicate the location of the route forwarding device, and the message signal strength of the data packet is used to indicate the distance between the terminal and the route forwarding device, so that the terminal can more accurately determine the actual location of the terminal according to the location of the route forwarding device and the distance between the terminal and the current terminal.
Further, the terminal may also receive data packets sent by a plurality of routing forwarding devices around, determine packet signal strengths of the plurality of data packets, send a positioning request to the server by using the plurality of data packets, obtain a plurality of location information, and determine actual location information of the terminal by using the plurality of location information and the signal strengths of the corresponding data packets.
The plurality of location information may indicate the locations of the plurality of route forwarding devices, respectively, the signal strength of the corresponding data packet may indicate the distance between the current terminal and the corresponding route forwarding device, and the actual location of the terminal may be determined more accurately according to the locations and the corresponding distances of the plurality of route forwarding devices.
In summary, according to the method provided by the embodiment of the present disclosure, the route forwarding device may initiate a WIFI scan, obtain an identifier of at least one route forwarding device within a current WIFI scanning range and a corresponding route signal strength, and may enable, through the broadcast data packet, the terminal that receives the data packet to perform positioning according to the identifier of the at least one route forwarding device and the corresponding route signal strength that are carried in the data packet.
