For example, computer terminal 10 may also include... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.
[0023] It should be noted that the aforementioned one or more processors 102 and / or other data processing circuits are generally referred to herein as "data processing circuits". These data processing circuits may be embodied, in whole or in part, in software, hardware, firmware, or any other combination thereof.

[0027] Under the above operating environment, embodiments of this application provide a method for determining the duration of a target object's stay within a target area, such as... Figure 2 As shown, the method includes the following steps:
[0028] Step S202: Obtain the recording time sequence data of the target object within a first preset time period. The recording time sequence data is used to indicate the dwell time of the target object recorded by the base station. The recording time sequence data includes the dwell data of the target object recorded by the base station of the fringe cell in the target area and the dwell data of the target object recorded by the base station of the adjacent cell of the fringe cell.
[0029] Step S204: Divide the recorded time-series data into multiple time-series data sets in sequence, using the second preset duration as the unit;
[0030] Step S206: Determine the dwell time of the target object recorded by the base station in the target area in each time series data set;
[0031] Step S208: Add up the durations of the target object recorded by the base station in the target area in all time series data sets to obtain the target dwell time of the target object in the target area.
[0032] By following the steps described above, it is possible to determine the time when the target object is recorded by the edge cell within the target area, and divide the time recorded by the edge cell into multiple time series data sets. This allows for the accurate determination of the target object's dwell time in the edge cell and the total dwell time in the target area. This achieves the goal of accurately calculating the dwell time of the edge cell into the target area, thereby improving the technical effect of obtaining the dwell time of the target object within the target area and solving the technical problem of low accuracy in the dwell time of the target object.
[0033] It should be noted that "border cells" refer to base station cells in the border areas between different cities, where base station signals overlap and cover each other. When a user uses their mobile phone, they may occupy the base station signal of another city without leaving the city's border and this will be recorded.
[0034] It is understandable that if the duration recorded by the smog cell and the cells adjacent to the smog cell are added to the dwell time in each city, it will result in an excessively long dwell time in a certain city; if the duration recorded by the smog cell is not considered at all, it will result in an inaccurate dwell time in a certain city.
[0035] In step S202, if the signal sent by the target object is detected by the base station, it will be recorded by the base station. The target object includes terminal devices that can send signals, such as mobile phones.
[0036] In step S204, the division into multiple time-series data is based on the chronological order of the time when the time-series data is recorded.
[0037] In step S208, after determining the dwell time of the edge cell, the dwell time of the target object in the target area can be obtained by adding the recorded dwell time of other cells in the target area other than the edge cell.
[0038] Steps S202 to S208 are described below through specific embodiments.
[0039] In step S204, the recorded time-series data is divided into multiple time-series data sets in units of a second preset duration. Specifically, starting from the first time-series data, the interval duration between each recorded time-series data is detected sequentially. If the interval duration is detected to be greater than the second preset duration, all recorded time-series data before the next recorded time-series data is determined to be a time-series data set.
[0040] In practical application scenarios, if the recorded times are 10:01, 10:02, 10:04 and 10:15 respectively, and the second preset duration is 5 minutes, then the recorded times of 10:01, 10:02 and 10:04 are classified into set 1, and the recorded time of 10:15 is classified into set 2.
[0041] The frequency ratio of the number of times the target object is recorded by the fringe cell base station in the target area in each time series data set to the total number of times the target object is recorded by the fringe cell and the neighboring cell base station in each time series data set is determined; the product of the frequency ratio and the corresponding duration of each time series data set is determined as the initial duration of the target object being recorded by the fringe cell base station in the target area; the initial duration is corrected using the interval duration to obtain the duration of the target object being recorded by the fringe cell base station in the target area; the sum of the duration of the fringe cell base station in the target area and the duration of the other base station cells in the target area excluding the fringe cell is determined as the dwell time of the target object being recorded by the base station in the target area in each time series data set.
[0042] Specifically, taking the table below as an example, it contains three time-series data sets. The target area is a peripheral city A, and peripheral city B is adjacent to peripheral city A. It can be determined that the time range corresponding to set 1 is 10:01-10:05; the time range corresponding to set 2 is 10:11-10:18; and the time range corresponding to set 3 is 10:23-10:30.
[0043]
[0044] Frequency ratio of marginal city A in set 1 If the duration corresponding to set 1 is 5 minutes, then the initial duration corresponding to set 1 is 4 / 5. 5 = 1 minute.
[0045] In one optional approach, the initial duration is corrected using the interval duration to obtain the duration for which the target object is recorded by the fringe cell base station in the target area. This includes: dividing the interval duration according to preset parameters to obtain a first interval duration and a second interval duration; determining a first time series data set and a second time series data set before and after the interval duration; determining a first corrected duration by multiplying the first frequency ratio of the first time series data set by the first interval duration; determining a second corrected duration by multiplying the second frequency ratio of the second time series data set by the second interval duration; and correcting the initial duration using the first corrected duration and the second corrected duration to obtain the duration for which the target object is recorded by the fringe cell base station in the target area.
[0046] In some embodiments of this application, the step of correcting the initial duration using the first corrected duration and the second corrected duration includes: determining the sum of the initial duration of the first time series data set and the first corrected duration as the duration during which the target object is recorded by a base station in the target area within the first time series data set; and determining the sum of the initial duration of the second time series data set and the second corrected duration as the duration during which the target object is recorded by a base station in the target area within the second time series data set.
[0047] Optionally, the first interval duration and the second interval duration can be determined by: determining the ratio of the interval duration to the preset parameter as the first interval duration; and determining the difference between the interval duration and the first interval duration as the second interval duration.
[0048] Taking a preset parameter of 2 and an interval of 6 minutes between set 1 and set 2 as an example, the first interval is 3 minutes and the second interval is 3 minutes.
[0049] Taking the data in the table above as an example, the duration for which the target object in set 1 is recorded by the peripheral cell base station in the target area. =4 / 5 5+4 / 5 3=3.4; The duration for which the target object in set 2 is recorded by the peripheral cell base station in the target area. =Initial duration corresponding to set 2 + second duration interval = 1 / 3 7+1 / 3 3.
[0050] Taking the data in the table above as an example, the duration for which the target object is recorded by the fringe cell base station in the target area is equal to the dwell time of set 1 + the dwell time of set 2 + the dwell time of set 3.
[0051] The duration T(A) during which the target object is recorded by the fringe cell base station within the target area = + + =4 / 5 5 + 4 / 5 3 + 1 / 3 3 + 1 / 3 7 + 1 / 3 2.5 + 9 / 14 7 + 9 / 14 2.5 = 16.66 minutes.
[0052] After obtaining the duration of the target object in the target area, the method further includes: verifying the duration of the target object in the target area, and if the duration of the target object in the target area is greater than a preset duration threshold, determining that the duration of the target object in the target area has not passed the verification.
[0053] In practical applications, the travel trajectory of a target object can be determined by verifying the duration of its stay within the target area.
[0054] This application provides a device for determining the duration of a target object's stay within a target area, such as...
