Referring to fig. 4, a flowchart of an information processing method according to another exemplary embodiment of the present application is shown. The present embodiment is exemplified by applying the information processing method to the terminal shown in fig. 1. The information processing method includes:
step 401, determining a target location where the terminal is located.
The implementation process of this step may refer to the above description of step 201, and is not described herein again.
Step 402, acquiring BSSID files corresponding to the target location, where the BSSID files include BSSIDs of one or more WiFi networks around the target location.
The implementation process of this step can refer to the above description of step 202, and is not described herein again.
Step 403, when it is detected that the target object enters the target location, acquiring first WiFi environment information, where the first WiFi environment information includes BSSIDs of multiple WiFi networks around the terminal.
When the terminal detects that the target object enters the target place, first WiFi environment information is collected, and the first WiFi environment information comprises BSSIDs (basic service set identifiers) of a plurality of WiFi networks on the periphery of the terminal.
The first WiFi environment information may further include at least one of a signal strength, an acquisition time, and an encryption type. The signal strength is the network signal strength of the WiFi network. The acquisition time is the time when the terminal acquires the WiFi network.
In step 404, when one or more common BSSIDs exist in the first WiFi environment information and BSSID file, a target BSSID is determined among the one or more common BSSIDs.
When one or more common BSSIDs exist in the first WiFi environment information and BSSID file, a target BSSID is determined among the one or more common BSSIDs, including but not limited to the following several possible implementations.
In one possible implementation, when there is a common BSSID in the first WiFi environment information and BSSID file, the common BSSID is determined as the target BSSID.
In another possible implementation, when a plurality of common BSSIDs exist in the first WiFi environment information and BSSID file, one common BSSID is selected from the first WiFi environment information and the BSSID file according to a selection policy to determine as the target BSSID.
The selection strategy includes selecting the common BSSID with the greatest signal strength, or selecting the first scanned common BSSID, or receiving a user-selected common BSSID. The present embodiment does not limit the setting of the selection policy.
Illustratively, when the first WiFi environment information further includes signal strengths of a plurality of WiFi networks on the terminal side, the terminal determines a target BSSID among one or more common BSSIDs, which may include: when one or more common BSSIDs exist in the first WiFi environment information and BSSID file, the common BSSID with the largest signal strength is determined as the target BSSID.
Illustratively, when the first WiFi environment information further includes the acquisition time of a plurality of WiFi networks around the terminal, the terminal determines a target BSSID in one or more common BSSIDs, which may include: and when one or more common BSSIDs exist in the first WiFi environment information and BSSID file, determining the common BSSID with the earliest acquisition time as the target BSSID.
In another possible implementation manner, when detecting that the target object enters the target location, the terminal sends the location identifier of the target location to the server, and correspondingly, the server receives the location identifier and acquires the target BSSID corresponding to the location identifier according to the preset corresponding relationship. And the server sends the target BSSID to the terminal, and the terminal receives and stores the target BSSID correspondingly.
The preset corresponding relation comprises the relation between the place identification and the target BSSID.
For example, when one or more common BSSIDs exist in the first WiFi environment information and BSSID file, the terminal determines that the target BSSID is "EC: 26: CA:7E:38: 38" among the one or more common BSSIDs to store.
Step 405, acquiring the signal strength of the target WiFi network corresponding to the target BSSID at predetermined time intervals.
Optionally, when it is detected that the target object enters the target location, the terminal acquires WiFi information of a plurality of WiFi networks around the terminal at predetermined time intervals. Wherein the WiFi information includes BSSID and signal strength.
Optionally, when the target BSSID of the target WiFi network exists in the BSSIDs of the WiFi networks, the terminal acquires the signal strength corresponding to the target BSSID.
In step 406, determining a plurality of signal strengths of the target WiFi network acquired within a preset time period as a plurality of historical signal strengths.
When the target object is detected to enter the target place, the terminal determines a plurality of signal strengths of the target WiFi network acquired within a preset time period as a plurality of historical signal strengths every preset time period.
Wherein the preset time period is greater than the preset time interval.
For example, the predetermined time interval is 10 seconds, and the preset time period is 60 seconds, that is, the terminal determines 6 signal strengths of the target WiFi network acquired within 60 seconds as 6 historical signal strengths.
In step 407, it is determined whether the variation trend indicated by the plurality of historical signal intensities is a downward trend.
Optionally, the decreasing trend is a trend that the plurality of historical signal intensities decrease as a whole, that is, the plurality of historical signal intensities have at most k abrupt values, but the plurality of historical signal intensities decrease as a whole, and k is a positive integer.
Optionally, the descending trend is a trend in which the plurality of historical signal strengths decrease, that is, the plurality of historical signal strengths are in a negative correlation with the time parameter, and the plurality of historical signal strengths decrease with an increase in the time parameter.
The terminal determines whether the variation trend indicated by the plurality of historical signal strengths is a descending trend, and if the variation trend indicated by the plurality of historical signal strengths is a descending trend, step 408 is executed; and if the change trend indicated by the plurality of historical signal strengths is not a descending trend, determining that the target object still resides in the target place.
And step 408, when the change trend indicated by the plurality of historical signal strengths is a descending trend, determining that the target object leaves the target place.
Optionally, before the terminal determines whether the change trend indicated by the plurality of historical signal strengths is a descending trend, the terminal determines whether the similarity between the first WiFi fingerprint information and the second WiFi fingerprint information is smaller than a similarity threshold, and if the similarity is smaller than the similarity threshold, the step of determining that the target object leaves the target location is performed when the change trend indicated by the plurality of historical signal strengths is a descending trend.
And when the change trend indicated by the plurality of historical signal strengths is a descending trend, indicating that the target object is farther away from the target place, and determining that the target object is away from the target place.
In order to more accurately identify whether the target object leaves the target site, when the trend of change indicated by the plurality of historical signal strengths is a downward trend, determining that the target object leaves the target site includes, but is not limited to, the following two possible implementations.
In one possible implementation manner, when the variation trend indicated by the plurality of historical signal strengths is a descending trend and the signal strength of the target WiFi network acquired last time is less than the strength threshold value, it is determined that the target object leaves the target place.
Optionally, when the terminal determines whether the variation trend indicated by the plurality of historical signal strengths is a descending trend, the terminal determines whether the signal strength of the target WiFi network acquired last time is less than a strength threshold. And when the change trend indicated by the plurality of historical signal strengths is a descending trend and the signal strength of the target WiFi network acquired last time is smaller than the strength threshold value, determining that the target object leaves the target place.
Optionally, when the signal strength of the target WiFi network is greater than or equal to the strength threshold, the distance indicating that the target object is located at the target location corresponding to the target WiFi network is less than the first distance threshold.
The intensity threshold may be set by default at the terminal or may be user-defined. This embodiment is not limited thereto.
In another possible implementation manner, when it is detected that the target object enters the target place, motion data of the target object is acquired at predetermined time intervals, and the motion data is used for indicating the moving speed of the target object within the predetermined time intervals. When the change trend indicated by the plurality of historical signal strengths is a downward trend and the motion data satisfies the specified distant condition, it is determined that the target object leaves the target place.
It should be noted that, the above two possible implementation manners may also be implemented in combination, and when the two possible implementation manners are combined, the determining, by the terminal, that the target object leaves the target location includes: and when the change trend indicated by the plurality of historical signal strengths is a descending trend, the signal strength of the target WiFi network acquired last time is smaller than the strength threshold value, and the motion data meet the specified far-away condition, determining that the target object leaves the target place.
It should be noted that, for the process of determining that the target object leaves the target location when the three conditions are simultaneously satisfied, reference may be made to relevant details of the two possible implementation manners, and details are not described here again.
Optionally, the motion data includes at least one of a moving step number, a moving speed, and an acceleration of the target object within a predetermined time interval. Illustratively, the moving speed is an average speed, a maximum speed, or a minimum speed within a predetermined time interval, and the acceleration is an average acceleration, a maximum acceleration, or a minimum acceleration within a predetermined time interval.
Optionally, the terminal includes at least one sensor of a pedometer, a gravity sensor, a vibration sensor, a pressure sensor, and a gyroscope, and the terminal obtains the motion data of the target object through the at least one sensor.
For example, the terminal collects the number of moving steps of the target object within a predetermined time interval through a pedometer.
Optionally, the specified far condition comprises a condition for indicating that the distance of the target object from the target location is greater than a second distance threshold.
In one possible implementation, when the motion data is a number of moving steps counted within a predetermined time interval, the away condition is specified as the number of moving steps being greater than a step number threshold.
In another possible implementation, when the motion data is a moving speed counted within a predetermined time interval, the moving-away condition is specified as the moving speed being greater than a speed threshold.
In another possible implementation, when the motion data is an acceleration counted over a predetermined time interval, the distancing condition is specified as the acceleration being greater than an acceleration threshold.
The step number threshold, the speed threshold, and the acceleration threshold may be set by default in the terminal, or may be set by a user in a self-defined manner, which is not limited in this embodiment.
In the embodiments of the present application, the motion data and the specified distance condition are not limited, and the motion data is only used as the moving step number of the target object obtained by the pedometer, and the specified distance condition is used as an example when the moving step number is greater than the step number threshold.
Optionally, the terminal acquires the moving step number of the target object through the pedometer while acquiring the first WiFi environment information at predetermined time intervals.
Illustratively, the terminal acquires the number of moving steps of the user through a pedometer while acquiring the first WiFi environment information every 10 seconds.
Optionally, when it is detected that the target object enters the target location, the terminal obtains the number of moving steps of the target object through the pedometer at predetermined time intervals. When the terminal judges whether the change trend indicated by the historical signal strengths is a descending trend, the terminal judges whether the moving step number of the target object obtained by the pedometer in the last time is larger than the step number threshold value. When the change trend indicated by the plurality of historical signal strengths is a descending trend and the moving step number is greater than the step number threshold value, the terminal determines that the target object leaves the target place.
The step number threshold value can be set by the terminal in a default mode or can be set by a user in a self-defined mode. This embodiment is not limited thereto. Illustratively, when the predetermined time interval is 10 seconds, the step count threshold is 15 steps.
In an illustrative example, after the terminal detects that a user using the terminal enters a shop, the terminal acquires the signal strength of the target WiFi network every 10 seconds, and the terminal acquires 6 historical signal strengths of the target WiFi network within some 60 seconds, and when the 6 historical signal strengths are "-35 dbm", "-38 dbm", "-45 dbm", "-50 dbm", "-55 dbm", "-60 dbm" in chronological order. When the terminal judges that the variation trend indicated by the 6 historical signal strengths is a descending trend, the terminal determines that the user leaves the shop.
Optionally, before the terminal determines whether the change trend indicated by the plurality of historical signal strengths is a descending trend, the terminal determines whether the similarity between the first WiFi fingerprint information and the second WiFi fingerprint information is smaller than a similarity threshold, and if the similarity is smaller than the similarity threshold, the step of determining that the target object leaves the target location is performed when the change trend indicated by the plurality of historical signal strengths is a descending trend.
Optionally, when the terminal detects that the target object enters the target place, first WiFi fingerprint information is acquired, where the first WiFi fingerprint information includes WiFi information of a plurality of WiFi networks around the terminal; acquiring second WiFi fingerprint information of the terminal at preset time intervals; calculating the similarity between the first WiFi fingerprint information and the second WiFi fingerprint information; when the similarity is less than the similarity threshold, the step of determining that the target object leaves the target place when the trend of change indicated by the plurality of historical signal strengths is a downward trend and the motion data satisfies the specified distant condition is performed.
The first WiFi fingerprint information is acquired when the terminal detects that the target object enters the target place, and the WiFi information of the plurality of WiFi networks on the periphery of the terminal is acquired. The second WiFi fingerprint information is WiFi information of a plurality of WiFi networks around the terminal that are collected at predetermined time intervals after the terminal detects that the target object enters the target location.
In one possible implementation manner, the terminal obtains a first quantity of the common WiFi information between the first WiFi fingerprint information and the second WiFi fingerprint information and a second quantity of the WiFi information in the second WiFi fingerprint information, and determines a ratio of the first quantity to the second quantity as a similarity of the first WiFi fingerprint information and the second WiFi fingerprint information.
When the ratio of the first quantity to the second quantity is smaller than the similarity threshold, the terminal determines that the similarity of the first WiFi fingerprint information and the second WiFi fingerprint information is low, and continues to execute the subsequent step of judging whether the target object leaves the target place; when the ratio of the first number to the second number is greater than or equal to the similarity threshold, the terminal determines that the similarity between the first WiFi environment information and the second WiFi environment information is high, and determines that the target object still resides in the target place.
For example, when the terminal detects that the user enters a shop, the obtained first WiFi fingerprint information includes the WiFi information A, WiFi information B and the WiFi information C, the terminal collects the WiFi fingerprint information once every 10 seconds, and when the collected WiFi fingerprint information includes the WiFi information A, WiFi information D, WiFi information E, since a ratio of a first number (i.e., 1) of the common WiFi information (WiFi information a) to a second number (i.e., 3) of the WiFi information in the second WiFi fingerprint information is 1/3, which is less than 50% of the similarity threshold, the terminal continues to perform the subsequent step of determining whether the target object leaves the target location.
Since the exit of the target location is usually located in a fixed direction, before the terminal determines whether the variation trend indicated by the plurality of historical signal strengths is a downward trend, the terminal may first determine whether the moving direction of the target object belongs to a specified direction range, and if the moving direction of the target object belongs to the specified direction range, perform the step of determining that the target object leaves the target location when the variation trend indicated by the plurality of historical signal strengths is a downward trend.
Optionally, the terminal acquires the moving direction of the target object at predetermined time intervals. And when the absolute value of the difference value between the moving direction and the designated direction is smaller than the direction threshold, executing the step of determining that the target object leaves the target place when the change trend indicated by the plurality of historical signal strengths is a descending trend and the motion data meets the designated far-away condition.
Illustratively, the direction (including the movement direction, the specified direction, and the direction threshold described above) is represented by a direction angle.
Wherein, the designated direction is the direction corresponding to the exit of the target place. The designated direction may be a direction corresponding to a target location previously stored by the terminal, or may be a direction statistically obtained by the terminal from at least two historical departure directions corresponding to the target location. Wherein the at least two historical departure directions are directions in the history when the at least two objects depart from the target site.
Optionally, the terminal obtains historical directions of at least two objects leaving the target location from the server, and determines the designated direction according to the at least two directions. Illustratively, the terminal determines an average value of direction angles corresponding to at least two directions as a direction angle of the designated direction.
The direction threshold is set by the default of the terminal or is set by the user in a self-defining way. For example, the direction threshold is 60 degrees.
For example, the terminal acquires the current corresponding moving direction of the user through the direction locator while acquiring the first WiFi environment information every 10 seconds. For example, the direction locator is a magnetometer.
In one illustrative example, where the exit of the target site is located in a true south direction, the designated direction for the target site is the true south direction and the direction threshold is 60 degrees. When the terminal acquires that the moving direction of the user is 45 degrees south-east, the terminal determines that the absolute value of the difference value '45 degrees' between the moving direction '45 degrees south-east' and the designated direction 'south-direction' is less than the direction threshold '60 degrees', and then the subsequent step of judging whether the target object leaves the target place is continuously executed.
Optionally, when the change trend indicated by the plurality of historical signal strengths is a downward trend, before the target object is determined to leave the target location, the terminal acquires the recommendation information of the target location, and displays the recommendation information of the target location on a negative screen of the terminal.
The terminal acquires the recommendation information of the target place, and the method includes but is not limited to the following two possible implementation manners.

Illustratively, when the target place is a tourist scene area, the recommendation information of the target place is determined to be tourist strategy information.
In another possible implementation manner, the terminal sends a query request carrying the location identifier of the target location to the server, where the query request is used to instruct the server to obtain recommendation information corresponding to the location identifier according to the second correspondence, and feeds the recommendation information back to the terminal. Correspondingly, the terminal receives recommendation information fed back by the server. The second correspondence includes a correspondence between the place identification and the recommendation information.
Optionally, the terminal sends a query request to the background server, where the query request carries a location identifier of the target location, and correspondingly, the background server receives the location identifier of the target location, forwards the location identifier to the third-party server, and the third-party server obtains recommendation information corresponding to the location identifier according to the second correspondence, and feeds back the recommendation information to the terminal through the acquired server. And the terminal receives the fed back recommendation information.
In an illustrative example, as shown in fig. 5, the approach service application in the terminal includes a data collection module and a recommendation information management module. After the terminal detects that a user using the terminal enters a shop, the terminal acquires the signal intensity of the target WiFi network every 10 seconds through the data acquisition module, and when the 6 historical signal intensities of the target WiFi network acquired within 60 seconds are not in a descending trend, the user is determined to be still resident in a target place.
