Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

Embodiment one

Figure 1 is a flow chart of the method for determining the positioning mode provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where the positioning mode is selected before positioning. This method can be implemented by the device for determining the positioning mode provided by the embodiment of the present invention. For execution, the device may be implemented in the form of software and/or hardware, and the device may be integrated into a terminal with a positioning function, such as a smart phone, a tablet computer, or a smart wearable device. The method specifically includes the following steps:

S110. Obtain positioning information of other terminals within a preset range from the current terminal location, where the positioning information includes a positioning mode.

Wherein, the preset range refers to the range set in the current terminal, and the numerical range can be customized by the user. For example, an editing interface or setting options are provided in the device for determining the positioning mode provided in the embodiment of the present invention, and are input or selected by the user. Preset range, for example, 500 meters or 300 meters, etc. Since the environments of other terminals within the preset range are generally not much different from the current terminal, positioning information suitable for the current terminal can be obtained by acquiring the positioning information of all other terminals within the preset range.

Wherein, the positioning information refers to relevant information of other terminals during positioning, including but not limited to positioning mode, positioning coordinates, positioning time, distance from the current terminal, and terminal moving distance after positioning. Exemplarily, the way for the current terminal to obtain the positioning information of other terminals may be: receiving the positioning information broadcast by other terminals within the preset range through Bluetooth, or downloading the positioning information shared by the terminals within the preset range from the sharing server, or Actively send request messages to terminals within the preset range to obtain location information. It should be noted that, when the positioning information is obtained through Bluetooth broadcasting, the preset range is generally set to the transmission range of Bluetooth, for example, it may be 10m.

Wherein, the positioning mode refers to a positioning mode applied when the terminal is positioned. The optional positioning mode may be any one of the following: WiFi positioning, GPS (Global Positioning System, Global Positioning System) positioning and base station positioning.

Among them, WiFi positioning is a positioning mode that uses existing wireless networks to cooperate with WiFi hotspot information and positioning algorithms to determine the location of end users. The working principle of WiFi positioning is that the terminal opens WiFi, scans the WiFi hotspot information within the range of the terminal, sends the scanning result to the positioning server and sends a WiFi positioning request; the positioning server uses the unique MAC (Media Access Control) address of the terminal WiFi, through positioning Algorithms determine location information. It should be noted that WiFi positioning needs to consume the data traffic of the terminal, and can locate indoor and outdoor locations.

GPS positioning is a positioning mode that determines location information through the Global Positioning System. Its working principle is that the GPS receiver in the terminal obtains the current location and time stamp of different satellites, and the location information of the terminal can be obtained through calculation. It should be noted that GPS positioning consumes a lot of power for terminals and has high positioning accuracy. It can only locate outdoor locations, but not indoor locations.

Base station positioning is a positioning mode that obtains the location information of the terminal user through the operator's communication network. Its working principle is that the terminal obtains the arrival time or arrival time of the downlink pilot signals of different base stations by measuring the downlink pilot signals of different base stations. The time difference, combined with the coordinates of the base station, can be used to obtain the location information of the terminal through calculation. It should be noted that the positioning accuracy of the base station is relatively low, and the indoor and outdoor positions can be positioned.

In this embodiment, by acquiring the positioning information of other terminals, the positioning mode applied by other terminals is acquired.

S120. Determine the positioning mode of the current terminal according to the positioning information.

When there is only one other terminal within the preset range, there is only one positioning information acquired, and only one positioning mode is included in it, and this positioning mode is used as the positioning mode of the current terminal. When there are multiple other terminals within the preset range, there are multiple positioning information to be obtained, and there may be only one positioning mode corresponding to the multiple positioning information, or there may be multiple positioning modes. When there is only one positioning mode, the positioning mode As the positioning mode of the current terminal. When there are multiple positioning modes, one positioning mode may be selected as the positioning mode of the current terminal according to preset rules. In an achievable manner, when multiple positioning modes are included, the number of terminals using each positioning mode within a preset range may be counted, and the positioning mode that uses the largest number is used as the positioning mode of the current terminal.

In this embodiment, since different positioning modes have different advantages and are applicable to different environments, the power consumption of the terminal is also different. The positioning mode of the current terminal can be determined by acquiring the positioning modes included in the positioning information of other terminals within the preset range, so that the positioning mode suitable for the current terminal can be selected more quickly, and the power consumption of the terminal can be reduced.

In the technical solution of this embodiment, the positioning mode of the current terminal is determined by obtaining the positioning mode contained in the positioning information of other terminals, which solves the technical problems that the user selects the positioning mode subjectively, cannot quickly and accurately locate, and increases the power consumption of the smart terminal. Fast and precise positioning, the technical effect of reducing terminal power consumption.

On the basis of the above embodiments, after determining the positioning mode of the current terminal according to the positioning information, it may further include:

automatically enable the positioning mode of the current terminal;

Or, the user is prompted to enable the positioning mode of the current terminal.

Exemplarily, after the current terminal determines the positioning mode of the current terminal according to the positioning mode in the positioning information of other terminals, for example, the positioning mode can be base station positioning, the current terminal can automatically turn on the base station positioning mode to perform positioning and display the positioning result; or Currently, the terminal reminds the user of the positioning mode by voice or displaying the words "Please turn on the base station positioning mode" on the screen.

By directly enabling the determined positioning mode, or prompting the user to enable it, the problem of wasting time and increasing terminal power consumption by the user's subjective selection of the positioning mode is avoided, and fast positioning is realized.

Embodiment two

Fig. 2 is a flow chart of the method for determining the positioning mode provided by Embodiment 2 of the present invention. On the basis of the above-mentioned Embodiment 1, this embodiment further optimizes the determination of the positioning mode of the current terminal according to the positioning information to: when the acquired positioning mode When there are multiple positioning modes, multiple positioning modes are used as candidate positioning modes; positioning data of terminals using the candidate positioning modes for positioning are obtained respectively; and an optimal positioning mode is determined according to the positioning data as the positioning mode of the current terminal. Accordingly, the method specifically includes:

S210. Obtain positioning information of other terminals within a preset range from the current terminal location, where the positioning information includes a positioning mode.

S220. When there are multiple positioning modes acquired, use the multiple positioning modes as candidate positioning modes.

Wherein, for example, when the positioning modes included in the positioning information of more than one other terminal are different from each other, for example, the positioning mode obtained from one other terminal may be base station positioning, and the positioning mode obtained from two other terminals may be GPS positioning, the different positioning modes are determined as candidate positioning modes.

S230. Respectively acquire positioning data of terminals that use the candidate positioning modes for positioning.

Wherein, the positioning data refers to data related to the positioning mode of the terminal. Specifically, the positioning data may include at least one item of information data such as positioning time, positioning accuracy, or a motion trajectory of the terminal after positioning. The positioning time refers to the time point when the terminal turns on the positioning mode for positioning; the positioning accuracy refers to the proximity of positioning information such as positioning coordinates to the user's actual position; Movement trajectory, according to the movement trajectory, the user's actual movement trajectory and movement distance can be identified. Obtaining positioning data for each candidate positioning mode facilitates comparative analysis.

S240. Determine the optimal positioning mode as the positioning mode of the current terminal according to the positioning data.

Wherein, the optimal positioning mode refers to the most preferred and most suitable positioning mode.

In this embodiment, the candidate positioning mode is determined according to the positioning mode in the acquired positioning information, and after analyzing and comparing the positioning data of each positioning mode, the most preferred positioning mode is selected as the positioning mode of the current terminal among the candidate positioning modes , to avoid the user's subjective and tentative selection of the positioning mode.

Optionally, the positioning mode corresponding to the positioning data that meets at least one of the following conditions is used as the optimal positioning mode: the time difference between the positioning time and the positioning time of the current terminal is less than the preset time, the positioning accuracy is higher than the preset accuracy, and the post-positioning forecast It is assumed that there is no movement exceeding the preset distance within the time period.

Wherein, the time difference between the positioning time and the positioning time of the current terminal is less than the preset time means that the positioning time in the positioning data acquired by the current terminal and the positioning time of the current terminal may be, for example, the time interval between the current time is within the preset time range For example, when the preset time is 30 minutes and the current time is 8:30 am, the positioning time of the positioning mode that meets the requirements should be between 8:00 am and 8:30 am, and the positioning time of other terminals The closer the positioning time is to the current terminal, the higher the selection accuracy of the positioning mode is.

The positioning accuracy is higher than the preset accuracy means that when the current terminal determines the optimal positioning mode in the candidate positioning mode, a preset accuracy can be set. When the positioning accuracy in the positioning data of the candidate positioning mode is higher than the preset accuracy, The candidate positioning mode can be continued as the candidate positioning mode, otherwise, the candidate positioning mode is discarded.

No movement exceeding a preset distance within a preset period of time after positioning refers to identifying motion trajectory data in the positioning data acquired by the current terminal, and judging the moving distance of other terminal users after positioning. Exemplarily, when other terminal users move beyond the preset distance after positioning, for example, the preset distance can be 100m or 200m, etc., the positioning mode may not be applicable to the current terminal, for example, in the mall If the positioning data obtained by the current terminal in the positioning mode of other terminals shows that the movement trajectory of other terminal users after positioning is from outdoors to indoors, then this positioning mode is not applicable to the current terminal.

In the technical solution of this embodiment, the candidate positioning mode is determined according to the positioning mode in the acquired positioning information, and after analyzing and comparing the positioning data of each positioning mode, the most preferred positioning mode is selected as the current positioning mode among the candidate positioning modes. The positioning mode avoids the user's subjective and tentative selection of the positioning mode, realizes fast positioning, and reduces the power consumption of the terminal.

Embodiment three

Accordingly, the method specifically includes:

S310. Obtain positioning information of other terminals within a preset range from the current terminal location, where the positioning information includes a positioning mode and positioning data related to the positioning mode.

Exemplarily, after each terminal is positioned, it can share the positioning information of the terminal through Bluetooth broadcasting or information sharing, so that other terminals can obtain the positioning information. The current terminal may acquire other positioning data shared by other terminals while acquiring the positioning mode in the positioning information.

It should be noted that if other terminals are authorized terminals, the shared positioning information may contain corresponding positioning data, such as positioning coordinates, etc.; when the current terminal is also an authorized terminal, the positioning data of other terminals may be directly used to determine the positioning mode .

For example, when the terminal is authorized, it can add positioning data to the broadcast information. When the current terminal searches the broadcast and finds that the positioning time in the broadcast information is short, the accuracy is small, and there is no long-distance movement track, it can directly use the broadcast information. The positioning data in the broadcast determines the positioning mode of the current terminal, which can reduce the positioning frequency of the terminal to a certain extent.

S320. Determine an optimal positioning mode according to the positioning data, and use the optimal positioning mode as a positioning mode of the current terminal.

In this embodiment, an optimal positioning mode is determined according to the positioning mode and positioning data simultaneously acquired in the positioning information, and the optimal positioning mode is used as the positioning mode of the current terminal.

Optionally, the positioning mode corresponding to the positioning data that meets at least one of the following conditions is used as the optimal positioning mode: the time difference between the positioning time and the positioning time of the current terminal is less than the preset time, the positioning accuracy is higher than the preset accuracy, and the post-positioning forecast It is assumed that there is no movement exceeding the preset distance within the time period.

In the technical solution of this embodiment, the optimal positioning mode is determined according to the positioning mode and positioning data obtained simultaneously in the positioning information, and the optimal positioning mode is used as the positioning mode of the current terminal, which avoids the subjective selection of positioning by the user. Mode, waste time and increase terminal power consumption, to achieve fast positioning.
