It should be understood that the described embodiments are merely some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The terminology used in the embodiments of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

Fig. 1 is a flowchart of a beam scanning error determining method according to an embodiment of the present application. As shown in fig. 1, the beam scanning error determining method may include:
step 101, determining the coverage area information of each wave beam in the cell according to the position information of the cell and the number of wave beams contained in the cell.
In the embodiment of the application, the cell information can be acquired according to the preset time interval. The acquired cell information may include: location information of a cell, cell azimuth, and the number of beams contained in the cell. The location information of the cell may be latitude and longitude information of a base station where the cell is located. The preset time interval can be set according to the actual situation, for example, 7 days. The set of cell information may be expressed as:
where k is the number of cells. j (j) 1 Longitude, j, of the first cell k Is the longitude of the kth cell. w (w) 1 Is the latitude of the first cell, w k Is the latitude of the kth cell. Alpha 1 For azimuth angle under first cell, α k Is the azimuth under the kth cell. N (N) 1 For the number of beams of the first cell, N k The number of beams for the kth cell.
After the cell information is acquired, coverage area information for each beam in the cell may be further determined.
First, a preset sector area in the azimuth direction of a cell is determined as a cell coverage area according to cell position coordinates. The central angle and the radius of the preset fan-shaped area can be set according to the actual situation.
Then, rootThe number of beams N contained in the cell divides the cell coverage area into N sub-areas. The N sub-areas are respectively determined as coverage areas of corresponding beams. The coverage area of each beam in a cell may be represented by a latitude and longitude range. The set of coverage areas for the individual beams in the cell can be denoted as s= { S 1 ，S 2 ，S 3 …S N }。
Step 102, determining the users in the coverage area of each wave beam according to the position information of the users in the cell and the coverage area information of each wave beam.
In the embodiment of the application, the report information of the user in the preset time period is received and counted. The report information of the user comprises: location information of the user and access beam of the user. The location information of the user may be latitude and longitude information of the location where the user is located. The preset time period can be set according to actual needs. For example, a day may be set.

The set of users within the coverage area of each beam can be expressed as: su= { S 1U ，S 2U ，S 3U …S NU }。
Step 103, determining access beam information of users in each beam coverage area.
In the embodiment of the application, since the reported information of the user includes the access beam of the user, after the user in each beam coverage area is determined, the access beam information of the user in each beam coverage area can be further determined. The set of access beam information for users within each beam coverage area can be expressed as: s is S UL ＝{S 1UL ，S 2UL ，S 3UL …S NUL }。
Step 104, determining the misconnection rate of each wave beam according to the access wave beam information of the users in the wave beam coverage area.
In the embodiment of the application, the misconnection rate of each wave beam in the cell can be determined by adopting the same method. A method for determining the beam error rate will be described herein by taking the first beam included in the cell as an example.
First, misaccess data of a first beam is determined according to access beam information of users in a coverage area of the first beam.
Because the first beam may have beam scanning errors, the access beam of users within the coverage area of the first beam may not be the first beam, but other beams contained in the cell. In the embodiment of the application, the data of which the access beam in the coverage area of the first beam is not the first beam is used as the misconnection data. The method of determining misconnection data for the first beam is as follows.
And determining the number of users in the first beam coverage area, of which the access beam is not the first beam, according to the access beam information of the users in the first beam coverage area in a preset time period.
And determining the total times of the access beams of the users in the first beam coverage area and the times of the access beams of the users in the first beam coverage area not being the first beam according to the access beam information of the users in the first beam coverage area in a preset time period.
Then, the misconnection rate of the first beam is determined according to the misconnection data of the first beam.
In the embodiment of the application, the misconnection rate of the first beam can be calculated according to the following formula:
P OUT ＝{a×N OUT +b×M OUT }/{N+M}
wherein P is OUT Is the misconnection rate. N (N) OUT The number of users within the coverage area of the first beam that access the beam that is not the first beam. M is M OUT Accessing the number of times the beam is not the first beam for the user within the coverage area of the first beam. N is the number of users located within the beam coverage area of the first beam. M is the total number of times a user accesses a beam within the coverage area of the first beam. a is a first weight and b is a second weight.
Wherein the first weight a and the second weight b are used for representing N OUT And M OUT The degree of influence on the misconnection rate can enable the calculation result of the misconnection rate to be more accurate. Since in actual case N OUT The degree of impact on the misconnection rate is typically greater than M OUT Thus, the first weight a is greater than the second weight b. The magnitudes of the first weight and the second weight can be determined according to the actual situation. For example, the first weight may be set to 0.7, the second weight to 0.3, and the sum of the first weight and the second weight to 1.
For example. If the access beam in the coverage area of the first beam is not the number N of users of the first beam OUT For 3 times M that the user access beam is not the first beam within the coverage area of the first beam OUT The number of users N located in the coverage area of the first beam is 10, and the total number of times M of access of the users to the beam in the coverage area of the first beam is 20. The first weight a is 0.7 and the second weight b is 0.3. At this time, the misconnection rate P of the first beam OUT ＝{0.7×3+0.3×6}/{10+20}＝13％。
Step 105, if the misconnection rate P of the beam OUT Greater than a preset threshold value P gap Then the corresponding beam scanning error is determined.
In the embodiment of the application, a threshold value P is preset gap The size of (2) can be set according to the actual situation. For example, 30% may be set. I.e. when the misconnection rate of the beam is greater than 30%, the beam scanning error is determined. The above examples are still presented. The misconnection rate P of the first wave beam OUT 13% less than a preset threshold value P gap 30%, therefore, no scanning error occurs in the first beam.
In the embodiment of the application, firstly, the coverage area information of each wave beam in the cell is determined according to the position information of the cell and the number of wave beams contained in the cell. Then determining the users in the coverage area of each wave beam according to the position information of the users in the cell and the coverage area information of each wave beam; and determining access beam information for users within each beam coverage area. And finally, determining the misconnection rate of each wave beam according to the access wave beam information of the users in the wave beam coverage area. If the misconnection rate of the beam is greater than a preset threshold, determining that the corresponding beam scans wrong. Thereby realizing effective determination of the scanning error of the whole network beam.

In the embodiment of the present application, a specific method for determining coverage area information of each beam in a cell may be: as shown in fig. 2, a preset sector area in the azimuth direction of the cell is determined as a cell coverage area by taking the coordinate o of the location of the cell as the center of a circle. As shown in fig. 2, the central angle of the preset sector area may be equal to the horizontal lobe width. The radius L of the preset sector area can be determined according to the actual situation.
