The current cell identification method can only identify and obtain the resident base station cell of the user, and when one base station comprises a plurality of physical cells, the physical cell where the user actually lives cannot be accurately positioned, which brings inconvenience to the stationing point marketing of operators. In view of the foregoing problems, an embodiment of the present invention provides a method for identifying a resident physical cell. Fig. 1 is a flowchart illustrating a resident physical cell identification method according to an embodiment of the present invention, as shown in fig. 1, the method includes:
and 110, acquiring the user resident base station based on the user signaling data.
Here, the user signaling data is signaling data of a user who needs to perform resident physical cell identification, and the signaling data may be from a smart phone or from a communication tool such as a smart watch. The user signaling data may be obtained by extracting signaling data of the mobile core network and the wireless side, for example, the user signaling data is obtained through an a (abis) interface and an S1-MME (Mobility management entity) interface. The user resident base station is a resident base station of a user acquired based on user signaling data, and here, there are various methods for acquiring the user resident base station based on the user signaling data, for example, the user resident base station is acquired by a spatial clustering method, and for example, the resident cell information of the user activity is counted based on a preset rule, so as to identify the user resident base station.
120, acquiring a preset number of adjacent base stations based on the user resident base station; the nearby base station is the base station closest to the user's resident base station based on the user signaling data acquisition.
Specifically, after the user resident base station is obtained, a preset number of base stations closest to each other are selected from each base station as neighboring base stations based on the distance between the user resident base station and each base station around the user resident base station appearing in user signaling data. Here, the preset number is a preset number of neighboring base stations, for example, the preset number is 3, and the first three base stations closest to the user resident base station are selected from each base station appearing in the user signaling data as the neighboring base stations.
130, selecting a resident physical cell from each physical cell based on the distance between each physical cell corresponding to the user resident base station and each adjacent base station and the all-day resident data of each adjacent base station; the all-day camping data of the adjacent base station is acquired based on the user signaling data.
Specifically, the all-day camping data of the neighboring base station is data acquired based on the user signaling and appearing in the neighboring base station all day by the user within a preset period. The physical cell corresponding to the user resident base station refers to a physical cell within the coverage range of the user resident base station cell, and whether any physical cell is the physical cell corresponding to the user resident base station or not can be judged by calculating the distance between the user resident base station and the central point of the physical cell and comparing the distance with the coverage radius of the user resident base station. There may be more than one physical cell corresponding to the user's resident base station.
And after the physical cell and the adjacent base station corresponding to the user resident base station are obtained, calculating the distance between each physical cell and the adjacent base station. And then, based on the distance between the physical cell and the adjacent base station and the all-day resident data of the adjacent base station, selecting one physical cell from all the physical cells corresponding to the user resident base station as a resident physical cell. For example, the distance between the physical cell and the neighboring base station and the all-day residence data of the neighboring base station are input into a pre-trained model, the resident physical cell output by the model is obtained, the score of each physical cell is calculated according to the distance between the physical cell and the neighboring base station and the all-day residence data of the neighboring base station, and the resident physical cell is selected according to the score.

The night stay duration is duration that a user appears in the base station at night within a preset time, and the night stay is here the number of times that the user appears in the base station at night within the preset time. For example, the preset time period is every odd days in one month, the night is set to 00:00 to 06:00, and one day is divided into 24 time periods, so that the night residence time of any base station is the accumulated time length of residence of every odd days 00:00 to 06:00 users in the base station in one month, and the night residence time of any base station is the accumulated hours of residence of every odd days 00:00 to 06:00 users in the base station in one month.

Based on any of the above embodiments, step 130 further includes: acquiring all-day resident data of each adjacent base station in a preset date based on user signaling data; the all-day residence data comprises all-day residence time and/or all-day residence times.
Specifically, the all-day camping data is data acquired based on user signaling and appearing in the base station by the user all day within a preset period. The all-day residence time is the time length of the user appearing in the base station all day in the preset time, and the all-day residence is the times of the user appearing in the base station all day in the preset time. For example, the preset period is every odd-numbered day in one month, and one day is divided into 24 time periods, so that the all-day residence time length of any adjacent base station is the accumulated time length of each odd-numbered day user residing in the base station in one month, and the all-day residence times of any adjacent base station is the accumulated hours of each odd-numbered day user residing in the base station in one month.
The whole-day residence time and the whole-day residence times of any adjacent base station are as follows:
in the formula, thi' and tdi' the total resident time length and the total resident times, th of the ith adjacent base stationijk' is the residence time of the ith adjacent base station in the jth time period on the kth day, tdijk' is the residence time of the ith adjacent base station in the jth time period on the kth day, j is the whole day time period, and k is the preset time period.
Based on any of the above embodiments, step 130 specifically includes:
and 131, aiming at any physical cell, acquiring an influence factor of the physical cell based on the distance between the physical cell and each adjacent base station and the all-day resident data of each adjacent base station.

Further, step 131 specifically includes: normalizing the all-day residence time of each adjacent base station to obtain the all-day normalized time of each adjacent base station; normalizing the all-day residence times of each adjacent base station to obtain the all-day normalized times of each adjacent base station; normalizing the distance between each physical cell and each adjacent base station to obtain the normalized distance between each physical cell and each adjacent base station; and acquiring the influence factor of the physical cell based on the normalized distance between any physical cell and each adjacent base station, the all-day normalized time length and the all-day normalized times of each adjacent base station.
Specifically, the normalized time length of any adjacent base station in the whole day is obtained according to the following formula:
in the formula (I), the compound is shown in the specification,
normalized time length, th, of the ith neighbor base stationi' is the whole day residence time length, max (th) of the ith neighbor base stationi') and min (th)i') are the maximum and minimum values, respectively, of the all-day dwell time period for each neighboring base station.

is the normalized distance, len, between the mth physical cell and the nth neighboring base stationmnIs normalized between the mth physical cell and the nth adjacent base stationDistance, max (len)mn) And min (len)mn) Respectively the maximum and minimum of the distance between each physical cell and each neighbouring base station.
After the all-day normalized time length and the all-day normalized times of each adjacent base station and the normalized distance between each physical cell and each adjacent cell are obtained, for any physical cell, the influence factor of the physical cell is obtained based on the normalized distance between the physical cell and each adjacent base station and the all-day normalized time length and the all-day normalized times of each adjacent base station.
Further, the impact factor of the physical cell is obtained by the following formula:
in the formula, affnFor the impact factor of the nth physical cell,
and
respectively the all-day normalized time length and the all-day normalized times of the mth adjacent base station,
is the normalized distance, w, between the nth physical cell and the mth neighboring base stationth、wtdAnd wlenRespectively, time length weight, frequency weight and distance weight, and l is the number of adjacent base stations.
Here, the time length weight, the order weight, and the distance weight in the above equation are set in advance. For example, the weights may be adjusted according to sample data obtained by sampling based on a logistic regression algorithm to obtain an approximation optimal for the influence factors, and further determine the final duration weight, the frequency weight, and the distance weight.
Based on any of the above embodiments, a resident physical cell identification method includes the following steps:
first, based on the user signaling data obtained by the interface a and the interface S1-MME, the time length th for the base station to appear in each time period (each day is divided into 24 time periods) is obtainedijkAnd number of times tdijkWherein i is the base station number, i is 1,2, …, n is the total number of base stations; j is a time period, j is 0,1,2, …, 23; k is a preset date for indicating a specific date.

In order to reflect the generality, 5 days are selected in the upper, middle and lower ten days, 15 days are used as sampling points, and the night is set to be 00:00 to 06:00, then:
