The embodiment of the application provides an interference evaluation method applied to a communication network. In the following, the interference evaluation method will be described in detail by taking the communication network as an LTE network as an example. The interference assessment method may be performed by any computer device. As shown in fig. 1, the method includes S101-S106:
s101, acquiring the work parameter information and the measurement report MR of the communication network.
Wherein the communication network is an LTE network. The work parameter information comprises: a cell name, a cell number (CI), a Location Area Code (LAC), a cell longitude and latitude, and a direction angle. The MR comprises: cell number, Cell name, frequency point, Physical Cell Identifier (PCI), RSRP.
S102, determining the position of the main service cell and the position of the adjacent cell according to the work parameter information.
The primary serving cell is a cell in the communication network, which needs to be subjected to interference evaluation. The neighboring cell is a cell within the coverage of the main serving cell in the communication network.
Specifically, the work parameter information includes a cell name, CI, LAC, a cell longitude and latitude, and a direction angle of each cell. And determining the geographical position of each cell according to the longitude and latitude of each cell in the work parameter information.
S103, determining the interference ratio between the main service cell and each adjacent cell according to the MR.
Wherein the interference ratio is a ratio of the signal received power of the main serving cell and the signal received power of the neighboring cell.
Specifically, the reference signal received power RSRPsc of the main serving cell and the reference signal received power RSRPnc of the neighboring cell are obtained from the MR.
And if the RSRPnc minus the RSRPnc is larger than a first threshold value, ignoring the interference ratio between the main service cell and the adjacent cell.
If the RSRPnc subtracted from the RSRPsc is larger than a second threshold and smaller than or equal to a first threshold, the interference ratio between the main serving cell and the neighbor cell is as follows:
if the RSRPsc is less than or equal to the RSRPnc, the interference ratio between the main service cell and the adjacent cell is as follows:
illustratively, the first threshold is 6db and the second threshold is 0 db.
In the current LTE network, when RSRPsc > RSRPnc, the larger the interference ratio between cells, the larger the interference of the neighboring cell received by the main serving cell. Generally, when the inter-cell interference ratio is greater than 16.7%, the interference of the neighboring cell received by the main serving cell is considered to be large; and performing important interference monitoring or adjustment on the adjacent cell. If the inter-cell interference ratio is greater than 33.3%, the interference of the neighboring cell on the main serving cell is considered to be serious, and the main serving cell or the neighboring cell needs to be optimized as fast as possible to reduce the interference of the neighboring cell on the main serving cell. If the RSRPsc is less than or equal to the RSRPnc; it is indicated that there is a cell with signal strength higher than that of the main serving cell in the neighboring cells, but no handover occurs, and it is necessary to detect whether there is a neighbor cell missing or a neighbor cell access difficulty, etc.
S104, dividing the coverage area of the main service cell into a plurality of areas according to a preset rule, and determining the area of each adjacent cell.
Specifically, the method for establishing the 360-degree coverage interference model comprises the following steps: and dividing the coverage area of the main service cell into a plurality of partitions according to a preset angle by taking the main service cell as a center. Dividing the coverage area of the main service cell into n layers; for each partition, dividing an area which is a first preset distance away from the main service cell into a first layer; dividing an area with a distance from the main service cell greater than a first preset distance and less than a second preset distance into a second layer; until dividing the area with the distance from the main service cell larger than the n-1 preset distance and smaller than the n preset distance into the n layer. And determining the area of each neighboring cell according to the position of each neighboring cell.
Illustratively, as shown in fig. 2, a 360-degree coverage partition model is established for the primary serving cell. The coverage area of the primary serving cell is first partitioned, for example, the coverage area is uniformly divided into 12 partitions with the median line of the cell antenna azimuth as a starting point (i.e., 0 degree) and with 30 degree intervals. Each partition is numbered, for example, the partition is divided by the coverage of the main lobe, the side lobe and the rear lobe of the antenna. The areas covered by the main lobe of the antenna (the area between 0-60 degrees and the area between 300-360 degrees) are labeled as the first, second, eleventh and twelfth sectors. The areas covered by the antenna side lobe areas (the area between 60 degrees-120 degrees and the area between 240 degrees-300 degrees) are labeled as a third partition, a fourth partition, a ninth partition and a tenth partition. The antenna back lobe area coverage area (the area between 120-240 degrees) is labeled as fifth, sixth, seventh and eighth zone. Then, the coverage area of the primary serving cell is layered, for example, the neighboring cells of the same station are divided into layer 0, and generally, a site includes three cells, and the three cells together complete signal coverage on the coverage area, and the three cells can be regarded as non-interfering. The area with the main serving cell as the center and the distance r as the radius is determined as the first layer (the distance r can be different according to the coverage scenes such as dense urban areas, general urban areas, suburban areas, rural areas and the like, for example, the distance r is generally 100 meters in the dense urban areas and 200 meters in the general urban areas). The area between r and 2r centered on the primary serving cell is the second layer. The area other than the area with the radius of 2r around the main serving cell is the third layer.
And S105, determining an interference coefficient generated by each region to the main service cell according to the interference ratio between the main service cell and each adjacent cell.
Specifically, the interference ratio of each neighboring cell in a first partition is summed to determine an interference coefficient of the first partition to the primary serving cell; the first partition is any area within the coverage area of the primary serving cell.
Illustratively, in a specific interference evaluation process, after a 360-degree coverage partition model is established for the primary serving cell numbered 410689_1, the interference in the first partition is evaluated. The determination of the area of each neighboring cell by the common reference information is shown in table 1:
| primary serving cell _ ID | Neighbor _ ID | Partitioning | Layering |
| 410689_1 | 411538_3 | 1 | 1 |
| 410689_1 | 411538_1 | 1 | 1 |
| 410689_1 | 411538_2 | 1 | 1 |
| 410689_1 | 410859_1 | 1 | 2 |
| 410689_1 | 410859_2 | 1 | 2 |
| 410689_1 | 410877_1 | 1 | ≥3 |
| 410689_1 | 410880_3 | 1 | ≥3 |
TABLE 1
The interference ratio between each neighboring cell and the main serving cell obtained by obtaining the MR measurement report of the main serving cell is, for example, as shown in table 2:
| primary serving cell _ ID | Neighbor _ ID | Partitioning | Layering | Inter-cell interference ratio |
| 410689_1 | 410859_1 | 1 | 2 | 16.76％ |
| 410689_1 | 410859_2 | 1 | 2 | 26.46％ |
| 410689_1 | 410877_1 | 1 | ≥3 | 26.76％ |
| 410689_1 | 410880_3 | 1 | ≥3 | 17.72％ |
TABLE 2
And summing the inter-cell interference ratios in the table 2, and regarding the area of the layer 0 and the first layer as a reasonable overlapping coverage area, wherein the interference generated by the adjacent cell in the area to the main service cell is not counted in the interference coefficient statistics. The interference coefficient generated by the first partition to the primary serving cell is determined as shown in table 3:
TABLE 3
And S106, evaluating the interference degree of each region to the main service cell according to the interference coefficient generated by each region to the main service cell.
Wherein the interference degree can be divided into a plurality of interference levels.
Specifically, if the number of the neighboring cells in the first partition is greater than a first threshold, the interference coefficient generated by the first partition to the primary serving cell is determined. And dividing the interference degree of the first partition on the main service cell into a first interference level to an nth interference level. The interference coefficient of each region is divided into a first section to an nth section. If the interference coefficient generated by the first partition to the main service cell is located in the mth interval, the interference level of the first partition to the main service cell is the mth interference level; wherein m is more than or equal to 1 and less than or equal to n.
Illustratively, the interference coefficient is divided into four intervals. Wherein the first interval is (0, 33.3%); the second interval was (33.3%, 50%); the third interval is (50%, 100%); the fourth interval is (100%, ∞). The interference level is divided into 4 interference levels, the first interference level representing interference mild interference. The second interference level represents medium interference and the third interference level is stronger interference; the fourth interference level is strong interference. The interference coefficient interval corresponds to the interference grade. Optionally, if the number of the adjacent cells in the first partition is less than two, it is determined that the interference condition is normal. And if the number of the adjacent cells in the first partition is more than or equal to two, judging the interference level according to the scheme.
