In specific implementation, the technical scheme provided by the embodiment of the application can be flexibly applied according to actual needs.

For convenience of understanding, a method for processing wireless network cell coverage area information provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings:

fig. 1 is a view of an application scenario of a method for processing coverage information of a wireless network cell in this embodiment. The figure includes: network 10, server 20, memory 30. The server 20 obtains information of a plurality of base stations of the target cell through the network, including a main lobe direction, a positioning position, and the like, and obtains access times of the mobile device of the target cell through the network.

It should be noted that the underlying concepts of the example embodiments of the present application may not be altered if additional modules are added or removed from the illustrated environments. In addition, although fig. 1 shows a bidirectional arrow from the memory 30 to the server 20 for convenience of explanation, it will be understood by those skilled in the art that the above-described data transmission and reception also need to be implemented through the network 10.

It should be noted that the storage in the embodiment of the present application may be, for example, a cache system, or a hard disk storage, a memory storage, and the like. In addition, the method for processing the coverage area information of the wireless network cell provided by the present application is not only suitable for the application scenario shown in fig. 1, but also can be used for other possible application scenarios, and the embodiments of the present application are not limited.

Based on the above description, the method for processing the coverage area information of the wireless network cell provided in the embodiment of the present application may include the following steps:

as shown in fig. 2, first, determining a first signal coverage distance may be implemented as:

first, determine the first signal coverage distance

In step 201, the directional angle of the lobe direction of the target cell of the target base station is acquired.

In step 202, the coverage area of the target cell is divided into a plurality of preset ranges based on the direction angle.

In step 203, searching a neighbor base station closest to the target base station in each preset range, and determining a first signal coverage distance of the target cell based on a sector distribution condition of the neighbor base station in each preset range.

It should be noted that the first signal coverage distance is a theoretical coverage distance of the target cell.

As shown in fig. 3, when calculating the theoretical coverage distance of a cell, the related art divides a plane into four regions according to 90 °, and falls each station into 4 different regions based on an angle between a connection line between each station and an O base station and a due north direction line with the "O base station" as a center of a circle. And finding out the shortest distance station in each area as an effective station, wherein the distance between the shortest distance station and the effective station is the station spacing. The density and distance of nearby base stations in the main lobe direction range of a base station cell are not considered in the related technology, so that the theoretical coverage distance of the cell is not accurate enough.

Therefore, in the technical solution provided in the present application, when determining the theoretical coverage distance (inter-site distance) of a cell, the influence of distribution factors of nearby base stations in the main lobe direction is considered, and a related calculation method is proposed, as shown in fig. 4, assuming that a target cell is an a base station, and there are a B base station, a C base station, and a D base station around the target cell, in order to determine the theoretical coverage distance of the cell where the a base station is located, a direction angle of a lobe direction of the cell where the a base station is located is first obtained, as the a base station in the figure is composed of three sectors, each sector represents a lobe direction, and the direction angle may be different directions corresponding to different sectors.

Then, the coverage area of the cell where the a base station is located is divided into a plurality of preset ranges based on the direction angle, the preset ranges include a first range, a second range and a third range, the first range is a ± L1 °, the second range is a range from a-L1 ° to a- β °, the third range is a range from a + L1 ° to a + β °, wherein a is the direction angle of the lobe direction of the target cell, i.e., the direction angle in fig. 4, L1 ° is a first preset angle, β ° is a second preset angle, and β ° is greater than L1 °.

As shown in fig. 4, if the first predetermined angle L1 ° is 15 °, and the second predetermined angle β ° is 30 °, the entire coverage area of the cell in which the a base station is located is set to a ± 30 °, which is the entire range of 60 ° in fig. 4. Wherein the first range corresponds to a ± 15 °, which is the range of 30 ° in fig. 4, the second range corresponds to the range of a-15 ° to a-30 °, and the third range corresponds to the range of a +15 ° to a +30 °.

In some embodiments, after the preset ranges are defined, a neighbor base station closest to the target base station is searched in each preset range, and the first signal coverage distance of the target cell is determined based on the sector distribution of the neighbor base station in each preset range, and the specific process may be implemented as shown in fig. 5:

in step 501, a first base station closest to the target base station is searched in the first range, and a first candidate distance corresponding to the first range is determined based on the number of sectors of the first base station and the overlapping rate of the target cell and the cell of the first base station. As shown in fig. 4, the nearest D base station is searched within a ± 15 °, where the sector number N of the D base station is 3, and N > is 2, the distance R3 between the a base station and the two cells where the D base station is located is obtained, if N is 2, the first candidate distance R3 is R3, otherwise, the first candidate distance R3 is R3 0.8.

It should be noted that, considering that the coverage of the a base station needs to intersect with the coverage of the D base station in the vicinity, in order to ensure smooth handover of services, the coverage of the a base station needs to overlap with the coverage of the D base station in the vicinity by 30%. When the nearby D base station has 3 or more than 3 sectors, the coverage of the D base station is relatively sufficient, so the first candidate distance R3 is R3 × 0.8, and when the nearby D base station is only 2 sectors, the coverage of the nearby D base station is insufficient, so it is necessary to consider the distance between the a base station and the nearby D base station as the coverage of the cell where a30 ° is located, that is, to make the first candidate distance R3 equal to R3, to ensure that the coverage of the two can overlap, and ensure that the traffic can be switched smoothly.

In step 502, a second base station closest to the target base station is searched in the second range, and a second candidate distance corresponding to the second range is determined based on the number of sectors of the first base station and the overlapping rate of the target cell and the cell of the first base station. As shown in fig. 4, a nearest B base station is searched in a range from a-15 ° to a-30 °, where the sector number N of the B base station is 3, so that N > is 2, and the distance between the a base station and two cells where the B base station is located is R1; if N is 2, the second candidate distance R1 is R1, otherwise the second candidate distance R1 is R1 is 0.8.

It should be noted that, considering that the coverage of the a base station needs to intersect with the coverage of the neighboring B base station to ensure smooth handover of the service, the coverage of the a base station needs to overlap with the coverage of the neighboring B base station by 30%. When the nearby B bss have 3 or more than 3 sectors, the coverage of the B bss is sufficient, so that R1 is R1 × 0.8. When the neighboring B base station is only 2 sectors, the coverage area of the neighboring B base station is insufficient, so that it is necessary to consider the distance between the a base station and the neighboring B base station as the coverage area of the cell where the a base station is located, that is, to make R1 equal to R1, so as to ensure that the coverage areas of the two overlap and ensure smooth handover of services.

In step 503, a third base station closest to the target base station is searched in the third range, and a third candidate distance corresponding to the third range is determined based on the number of sectors of the first base station and the overlapping rate of the target cell and the cell of the first base station. As shown in fig. 4, a nearest C base station is searched in a range from a +15 ° to a +30 °, the sector number N of the C base station is 3, and N > -2, and the distance between the a base station and two cells in which the C base station is located is R3; if N is 2, the third candidate distance R2 is R2, otherwise the third candidate distance R2 is R2 is 0.8.

For the same reason, considering that the coverage of the a base station needs to intersect with the coverage of the nearby C base station to ensure smooth handover of the traffic, the coverage of the a base station needs to overlap with the coverage of the nearby C base station by 30%. When the nearby C base station has 3 or more than 3 sectors, the coverage of the C base station is sufficient, so let R2 be R2 × 0.8. When the neighboring C base station is only 2 sectors, the coverage area of the neighboring C base station is insufficient, so that the distance between the a base station and the neighboring C base station is directly taken as the coverage area of the cell where the a base station is located, that is, R2 is R2, so as to ensure that the coverage areas of the two overlap and ensure smooth handover of services.

In step 504, a mean of the second candidate distance and the third candidate distance is determined.

In step 505, the minimum of the first candidate distance and the mean is obtained as the first signal coverage distance.

As shown in fig. 4, the theoretical coverage distance r of the cell in which the a base station is located is calculated as min (r3, (r1+ r2)/2), that is, the minimum value of r3, (r1+ r2)/2 is taken as the first signal coverage distance.

It should be noted that, because the electromagnetic lobe of a base station is 60 degrees, and the intensity and the directivity in the range of 30 degrees are the strongest, the minimum value of the two is selected in consideration of the electromagnetic lobe characteristics of the base station, and the theoretical coverage distance of the cell is more consistent with the actual requirement.

It should be noted that, as shown in fig. 6(a), the coverage range of the D base station signal within 30 ° of the main lobe of the a base station is 360 °, and when r3< (r1+ r2)/2, as shown in fig. 3, it is illustrated that the B base station and the C base station are located above the D base station and there is no signal overlap with the a base station, so the a base station only needs to intersect with the D base station coverage, but does not need to intersect with the B base station and the C base station coverage, so the coverage distance of the a base station is preferably selected as r 3.

When (R1+ R2)/2< R3, as shown in fig. 6(B), the B base station and the C base station are located on both sides of the main lobe of the a base station by 60 °, and the D base station is located above the B base station and the C base station, and there is no signal overlap with the a base station.

Since the B base station and the C base station are positioned on two sides of the main lobe of the A base station by 60 degrees, and the coverage range of the B base station and the C base station is 360 degrees, the A base station only needs to be intersected with the coverage of the B base station and the C base station, but does not need to be intersected with the coverage of the D base station, and the coverage distance of the A base station is preferably selected to be (r1+ r 2)/2.

After the first signal coverage distance is determined, a second signal coverage distance is determined, and the second signal coverage distance is the actual coverage distance of the target cell.

Secondly, determining the coverage distance of the second signal

In step 204, a second signal coverage distance of the target cell is obtained, where the second coverage distance is a current signal coverage distance of the target cell.

In the related technology, the actual coverage distance of the cell is calculated, and the 32.45 free space loss, the loss of the area environment (loss caused by atmosphere, obstruction, multipath and the like), the carrier frequency and the like and the distance of the signal intensity received by the mobile phone in the range of the cell opposite to the direction at the position of-95 dBm are comprehensively considered mainly according to a link loss formula. The actual coverage distance algorithm is obtained by comprehensively evaluating the position information reported by daily ordinary mobile phone users, the data volume of the information reaches the million level, and the statistical significance is good. Fig. 7 shows a flowchart of a specific actual coverage distance determination method, which may be implemented as:

in step 701, acquiring statistical data of the time advance of the target cell; the statistical data comprises N partitions, and each partition comprises the access times of the time advance value in the range of the partition. As shown in fig. 8, statistical data of TA measured by PRS (position reference signal) in a week about RA is obtained, where the statistical data of TA is time advance, the statistical data includes 12 partitions, each partition TA (X) includes the number of accesses of a TA value in a partition range where the TA value is located, and X may be 0 to 11, for example, the number of accesses of a TA value in a 0 range is 1, 402, 15, and the like when a user randomly accesses in fig. 8, and may be understood as the number of accesses of a TA (0) interval is 1, 402, 15, and the like.

In step 702, the access times included in each partition are accumulated until the ratio of the accumulated value to the total access times of all the partitions is equal to or greater than the preset ratio. And accumulating all the access times in the same row in fig. 8 to obtain total data SUM _ NUM, and according to the two-eight law, taking 80% of SUM _ NUM as a cell MR sampling point scale, wherein the preset ratio is 80%.

It should be noted that, in the present application, according to the balanops law (i.e., the twenty-eight law), the problem of path increase caused by refraction and reflection of the wireless signal is considered, so that the problem of actual coverage distance increase caused by refraction and reflection of the wireless signal can be well reduced by taking 80% of the user distance information as the blueprint, and the misjudgment rate can be reduced.

In step 703, a second signal coverage distance of the target cell is determined based on the last partition involved in the accumulation calculation. The number of inputs obtained by each time of the accumulation calculation is denoted as COUNT _ NUM, and the ta (x) interval that satisfies the condition (COUNT _ NUM >: SUM _ NUM × 80%) at the earliest is taken as the actual coverage distance of the cell. If the last partition participating in the accumulation calculation is the last partition in all the partitions, that is, COUNT _ NUM is SUM _ NUM, the average value of the distances corresponding to the last partition is used as the second signal coverage distance; if the partition which is last involved in the accumulation calculation is not the last partition in all the partitions, namely COUNT _ NUM < SUM _ NUM, the maximum value of the distances corresponding to the partition which is last involved in the accumulation calculation is used as the second signal coverage distance.

It should be noted that ta (x) represents a distance interval (e.g. from 300 m to 2000 m); if COUNT _ NUM < SUM _ NUM, indicating that some users are farther away than the maximum value of the TA (X) interval value, the maximum value of the TA (X) interval is selected. If COUNT _ NUM is SUM _ NUM, it means that the distances from the user to the base station are all within the interval of ta (x), and the user distribution within the interval is generally estimated by using a normal distribution or uniform random distribution model, so the probability of taking the median of the interval values of ta (x) is the highest, and the error probability is the lowest.

It is added that since the signal instruction flow includes up and down, it needs to be divided by 2 when determining the final actual coverage distance. As shown in fig. 9, the distance corresponding to the number of random accesses of the user can be obtained by conversion according to the TA value, and if the duration of one TA is 0.52 μ sec, the corresponding access distance is:

0.52×10^-6×3×10⁸156 m

After dividing by 2, the resulting distance is 78. M2000 between the UE and the base station corresponding to one TA has 12 indexes in total to represent the TA value range for random access of the user, and thus, the correspondence relationship between the TA value and the access distance is shown in fig. 9.

After determining the first signal coverage distance and the second signal coverage distance, in step 205, an adjustment angle of a downtilt angle of an antenna of the target cell is determined based on the first signal coverage distance and the second signal coverage distance.

Thirdly, determining the adjustment angle

In some embodiments, the present network downtilt angle of the target cell antenna is first obtained, and then the adjustment angle of the target cell antenna is determined based on the adjustment angle determination formula (1):

where b is a constant, typically taken as 1, D represents the first signal coverage distance, D represents the second signal coverage distance, α represents the net roll angle, and θ represents the adjustment angle.

It should be added that, in order to analyze the relationship between the theoretical coverage distance of the target cell and the actual coverage distance of the target cell, a value "cell coverage adjustment factor λ" is defined in the present application to evaluate whether the coverage distance of the cell is reasonable, and the calculation formula (2) of the cell coverage adjustment factor λ is as follows:

wherein, the cell coverage adjustment factor λ generally takes two digits after the decimal point.

If lambda is more than 1 and the MR coverage rate is less than 90%, the cell has over-coverage; if λ < 0.5 and MR coverage < 90%, there is insufficient coverage for the cell.

Finally, in step 206, the antenna of the target cell is adjusted based on the adjustment angle.

According to the steps, under the current technical conditions, through the first signal coverage distance (inter-station distance) algorithm provided by the method, the influence of the distribution factors of the nearby base stations in the main lobe direction is considered, the influence of the number of sectors of the nearby base stations is also considered, the more accurate theoretical coverage distance can be calculated, the coverage network of the cell can be reasonably optimized, and the network quality is improved. In addition, the first signal coverage distance does not need to be determined manually, manual materials can be simplified, a large amount of time and resources are saved, and the method has higher efficiency.
