Description

Technical Field

[0001] The present invention relates to the field of wireless communication technology, and in particular to a method and device for acquiring co-coverage sectors. Background Art

[0002] As users' demands for the network increase, the network load problem becomes more and more serious. In high-load areas, high-load optimization is analyzed in the sector dimension, and the co-covered cells are analyzed and adjusted as the priority sectors. If a cell has too many people covered, it is impossible to determine the balancing solution for the high-load cell without clear co-coverage. Therefore, the identification and acquisition of co-covered cells becomes an important basis for high-load balancing.

[0003] There are two methods for obtaining co-coverage sectors in the prior art. One is to perform co-coverage judgment based on the relationship between the main cell and the neighboring cell based on the measurement report (MR) sampling data. The calculation accuracy is relatively high, but the disadvantage is that there are relatively few neighboring cell data of the sampling points in the actual production environment, and the calculation efficiency is low. The other is to perform envelope calculation on the MDT sampling point data based on the Minimization Drive Test (MDT) sampling point through the geographic information system. The advantage is that the verification accuracy is higher and the recognition result is more accurate. The disadvantage is that the operation cost of the entire set of geographic information system engines needs to be built. Summary of the invention

[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Figure 1 FIG. 1 is a flow chart of a method for acquiring a co-covered sector provided in an embodiment of the present invention. Figure 1 As shown, the present invention provides a method for acquiring a co-coverage sector, the method comprising:

[0038] Step 101, divide the cell area according to the preset distance to obtain the co-site cells.

[0039] Specifically, a preset distance is set, and the inter-base station distance between two base stations is less than the preset distance as a co-station cell identification standard. The cell area is divided according to the preset distance, and the cells within the preset distance are co-station cells.

[0040] Optionally, the preset distance is 50m.

[0041] Step 102: within each co-sited cell, a first co-coverage sector is acquired based on the azimuth angle of the cell and a preset co-coverage angle.

[0042] Specifically, within the scope of each co-sited cell, with the azimuth of the cell as the center, the cell and other cells within a preset co-coverage angle range of half of each side of the azimuth of the cell are regarded as co-coverage sectors.

[0043] There are one or more co-covered sectors in a co-site cell. Record the main cell azimuth, total cell number and sector angle of each co-covered sector.

[0044] Optionally, the preset total coverage angle is 30°.

[0045] Figure 2 FIG. 1 is one of the schematic diagrams of the co-coverage sector division provided by the embodiment of the present invention, such as Figure 2 As shown, there are four cells, namely, cell A, cell B, cell C and cell D. Cell A is the main cell. The common coverage area is 15° extended to both sides with the azimuth of cell A as the center. Within the common coverage area, there are cell A and cell B, so cell A and cell B are a common coverage sector.

[0046] Step 103: Screen the first co-covered sectors to obtain second co-covered sectors.

[0047] Specifically, among the acquired co-coverage sectors, there is a case where one cell belongs to multiple co-coverage sectors at the same time. In order to ensure that one cell belongs to only one co-coverage sector, it is necessary to screen the acquired co-coverage sectors to obtain the optimal co-coverage sector.

[0048] The method for acquiring co-coverage sectors provided in an embodiment of the present invention first divides the co-station cells, and then divides the co-coverage sectors according to the azimuth and preset co-coverage angles on the basis of the co-station cells. Finally, the divided co-coverage sectors are screened to achieve efficient acquisition of co-coverage sectors without relying on a geographic information system, thus saving the cost of acquiring co-coverage sectors.

[0049] Optionally, dividing the cell area according to the preset distance to obtain the co-site cell includes:

[0050] Divide the cell area into grids according to the preset distance to obtain grid coverage cells;

[0051] Co-station cells are divided based on the grid coverage cells and the preset distance to obtain co-station cells.

[0052] Specifically, Figure 2 Schematic diagram of grid division of a cell area provided by an embodiment of the present invention, such as Figure 2 As shown, the cell area is divided into grids, each grid has a side length of a preset distance of 50m, and the surrounding grids can be obtained by the X-axis and Y-axis in a step length of 50m. The area covered by each grid is regarded as a grid coverage cell.

[0053] The coordinate GRID_X expression of each grid on the X-axis is as follows:

[0054] GRID_X=Math.Floor(Longitude*100000 / 50.0)

[0055] In the formula, GRID_X represents the coordinate of the grid on the X-axis, and Longitude represents the longitude of the cell.

[0056] The GRID_Y expression of each grid coordinate on the Y axis is as follows:

[0057] GRID_Y=Math.Floor(Latitude*100000 / 50.0)

[0058] In the formula, GRID_Y represents the coordinate of the grid on the Y axis, and Latitude represents the latitude of the cell.

[0059] The expression for the grid number of each grid is as follows:

[0060] GRID_ID=(GRID_X,GRID_Y)

[0061] Where GRID_ID represents the grid number, GRID_X represents the grid coordinate on the X-axis, and GRID_Y represents the grid coordinate on the Y-axis.

[0062] like Figure 2 As shown, (1,1) represents a grid with a coordinate of 1 on the X-axis and a coordinate of 1 on the Y-axis. The grid number is used as a co-station identifier.

[0063] After obtaining the grid coverage cells, based on the grid coverage cells, the cells within the preset distance are obtained by precise distance calculation, and the cells within the preset distance are used as co-station cells, and the average coordinates of the cells in the co-station cells are used as the co-station material coordinates.

[0064] The method for acquiring co-covered sectors provided in an embodiment of the present invention first divides the cell area into a grid with a preset distance as the side length, and then performs accurate preset distance division based on the grid coverage cell, thereby minimizing the number of distance calculations, thereby reducing the time of the distance calculation cycle.

[0065] Optionally, the acquiring, within the range of each co-sited cell, a first co-coverage sector based on the azimuth angle of the cell and a preset co-coverage angle includes:

[0066] Within the scope of each co-sited cell, the azimuth angles of the cells are arranged in numerical order;

[0067] Starting from the smallest azimuth angle and taking the azimuth angle of the cell as the center, the cell within the coverage area corresponding to the preset common coverage angle is divided into common coverage sectors to obtain a first common coverage sector.

[0068] Specifically, within the scope of each co-sited cell, the azimuth angles of the cells are arranged in numerical order, such as from small to large, or from large to small.

[0069] Figure 4 is a schematic diagram of the common coverage provided by an embodiment of the present invention, such as Figure 4 As shown, the azimuth angles of the cells are arranged in ascending order of numerical value, namely 0°, 10°, 20°, 25° and 30°.

[0070] The co-coverage sectors are analyzed sequentially starting from the smallest azimuth angle, with the azimuth angle of the cell as the center, and the coverage range of the preset co-coverage angle half on both sides of the azimuth angle of the cell is taken as the co-coverage range.

[0071] like Figure 4 As shown, taking a cell with an azimuth angle of 20° as an example, with the azimuth angle of 20° as the center and extending 15° outward on both sides, the total coverage range is [5°~35°].

[0072] After analysis, it can be seen that within the coverage range of [5°~35°], there are cells with azimuth angles of 10°, 20°, 25° and 30°. Figure 5FIG. 2 is a second schematic diagram of the division of co-coverage sectors provided in an embodiment of the present invention. Figure 5 As shown, cells with azimuth angles of 10°, 20°, 25° and 30° are divided into a common coverage sector. The angle of the common coverage sector is the difference in azimuth angles of edge cells in the common coverage sector.

[0073] The method for acquiring co-coverage sectors provided by the embodiment of the present invention sorts the azimuth angles in the co-coverage sectors and analyzes the co-coverage sectors starting from the smallest azimuth angle, which is conducive to efficiently acquiring the co-coverage sectors.

[0074] Optionally, screening the first co-covered sector to obtain the second co-covered sector includes:

[0075] The first co-covered sectors are screened in sequence according to the principle that the number of all cells in the co-covered sector is the largest, the sector angle of the co-covered sectors is the smallest, and the azimuth angle of the main cell in the co-covered sectors is the smallest to obtain the second co-covered sector.

[0076] Specifically, the first round of screening is performed on the first co-covered cell based on the principle of the largest number of cells in the co-covered sector; then the second round of screening is performed on the first co-covered cell based on the principle of the smallest sector angle of the co-covered sectors; finally, the third round of screening is performed on the first co-covered cell based on the principle of the smallest azimuth angle of the main cell in the co-covered sector. The co-covered sectors remaining after three rounds of screening are the second co-covered sectors.

[0077] Taking the co-covered sectors with five different main cell azimuth angles of 0°, 10°, 20°, 25° and 30° as an example, Table 1 is a co-covered sector information table, which contains information on the coverage range, main cell azimuth angle, total number of cells and sector angle of each co-covered sector.

[0078] Table 1 Total coverage sector information table

[0079] Total sectors covered Coverage Main cell azimuth Total number of cells Sector Angle Total coverage sector 1 [0°～10]° 0° 2 10° Total coverage sector 2 [0°～25°] 10° 4 25° Total coverage of sectors 3 [10°～30°] 20° 4 20° Total coverage of sectors 4 [10°～30°] 25° 4 20° Total coverage of sectors 5 [20°～30°] 30° 3 10°

[0080] In the first step, according to the principle of having the largest number of cells in the co-covered sector, co-covered sector 2, co-covered sector 3 and co-covered sector 4 among the five co-covered sectors meet the requirements.

[0081] In the second step, the same cell cannot exist in multiple co-coverage sectors. The co-coverage sectors need to be screened based on the principle of the smallest sector angle. Among co-coverage sectors 2, co-coverage sectors 3 and co-coverage sectors 4, co-coverage sectors 3 and co-coverage sectors 4 meet the requirements.

[0082] In the third step, according to the principle that the azimuth angle of the primary cell in the co-covered sector is the smallest, among the co-covered sectors 3 and 4, only the co-covered sector 3 meets the requirement.

[0083] Therefore, the total coverage sector 3 is the screened total coverage sector.

[0084] The method for acquiring co-covered sectors provided in an embodiment of the present invention sequentially screens sectors based on the principles of the largest number of total cells in the co-covered sectors, the smallest sector angle of the co-covered sectors, and the smallest azimuth angle of the main cell in the co-covered sectors, which is beneficial to improving the accuracy of co-covered sectors.

[0085] Optionally, after acquiring the second co-coverage sector, the method further includes:

[0086] When the sector angle of the second co-coverage sector is smaller than a preset co-coverage angle, cell supplementation is performed on the second co-coverage sector.

[0087] Specifically, in order to avoid the problem that the cells under the co-sited cell do not exist in any co-covered sector, when the sector angle of the second co-covered sector is less than the preset co-covered angle, it is necessary to supplement the second co-covered sector to expand the sector angle of the second co-covered sector. The cell supplementation of the second co-covered sector is performed on the principle of minimizing the supplementary angle.

[0088] For example, the sector angle of 20° of the co-coverage sector 3 is smaller than the preset co-coverage angle of 30°, and the co-coverage sector 3 needs to be supplemented with a cell. The angle of supplementation of the co-coverage sector 3 is 10°, which is the difference between the preset co-coverage angle of 30° and the sector angle of 20°.

[0089] A cell search is performed on both cell sides of the sector of the co-covered sector 3, with a search range of [0°~10°] and [30°~40°]. After searching, only the cell with an azimuth angle of 0° is found to meet the requirements. Therefore, the cell with an azimuth angle of 0° is added to the co-covered sector 3. The co-covered sector 3 consists of five cells with azimuth angles of 0°, 10°, 20°, 25° and 30°, and the sector angle is 30°.

[0090] If it is found through searching that there is a cell with an azimuth angle of 0° in the range of [0°~10°], and there is a cell with an azimuth angle of 35° in the range of [30°~40°]. It can be seen that if a cell with an azimuth angle of 35° is supplemented, the supplementary angle is 5°; if a cell with an azimuth angle of 0° is supplemented, the supplementary angle is 10°. Based on the principle of minimum supplementary angle, the cell with an azimuth angle of 35° is supplemented to the co-covered sector 3. After cell supplementation, the sector angle of the co-covered sector 3 is 25°, and the co-covered sector 3 can be supplemented by 5°. No cell that meets the requirements is found in the search range of [5°~10°] and [35°~40°]. Finally, the co-covered sector 3 is composed of five cells with azimuth angles of 10°, 20°, 25°, 30° and 35°, and the sector angle is 25°.

[0091] The method for acquiring co-coverage sectors provided in the embodiment of the present invention avoids cell omission by supplementing co-coverage sectors whose sector angle is smaller than a preset co-coverage angle, which is beneficial to improving the accuracy of co-coverage sectors.

[0096] The third acquisition module 603 is used to screen the first co-covered sectors to acquire second co-covered sectors.

[0097] Optionally, the third acquisition module 603 is specifically used to: screen the first co-covered sectors in sequence according to the principle of the largest number of total cells in the co-covered sectors, the smallest sector angle of the co-covered sectors, and the smallest azimuth angle of the main cell in the co-covered sectors, to obtain the second co-covered sectors.
