[0155] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the accompanying drawings in the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0156] Neighboring cell planning refers to the process of determining the neighboring cells of a cell. Reasonable neighboring cell planning is of great significance in the processes of cell handover and cell reselection.

[0157] Currently, neighboring cell planning is mainly achieved by combining factors such as the distance and azimuth angle between the target cell and neighboring cells. For specific examples, reference can be made to Figure 1 the examples.

[0158] Figure 1 is a schematic diagram for determining neighboring cells, such as Figure 1As shown, two sites are exemplified, namely Site A and Site B.

[0159] For each site, the site includes multiple cells (each sector in Figure 1 corresponds to one cell). In Figure 1 the azimuth angles of Cell 1 under Site A and Cell 2 under Site B are exemplified respectively. In the embodiments of the present application, the azimuth angle of a cell is used to indicate the orientation of the cell antenna. The direction where the azimuth angle of the cell is located is the orientation of the cell antenna, that is, the direction of the center line of the cell coverage area. The azimuth angle of the cell is determined when planning the cell and belongs to a part of the engineering parameter information of the cell.

[0160] Connect the positions of Cell 1 and Cell 2. The angle between this connection line and the direction where the azimuth angle of Cell 1 is located is the Cell 1 angle, and the angle between this connection line and the direction where the azimuth angle of Cell 2 is located is the Cell 2 angle.

[0161] The types of sites include micro-sites and macro-sites, and the cell coverage types under the sites include micro-cells and macro-cells. For example, if Site A is a micro-site, the cell coverage type of Cell 1 under Site A is the micro-cell type; if Site B is a macro-site, the cell coverage type of Cell 2 under Site B is the macro-cell type.

[0162] After determining the cell coverage types of Cell 1 and Cell 2, combining the corresponding distance threshold and cell angle threshold, it is possible to plan whether Cell 1 and Cell 2 are neighboring cells to each other.

[0163] A possible distance threshold and cell angle threshold can be exemplified as shown in Table 1 below:

[0164] Table 1

[0165]

[0166]

[0167] In Table 1, different distance thresholds and cell angle thresholds are exemplified for various different situations of the cell coverage type of the current cell and the neighboring cell coverage type. Taking Figure 1 the cell coverage types of Cell 1 and Cell 2 in as both being macro-cells as an example, it corresponds to rows 1 - 5 in Table 1. Taking Cell 1 as the current cell, the meaning represented by the first row is that cells with a distance less than or equal to 200m from Cell 1 are all regarded as neighboring cells of Cell 1. The meaning represented by the second row is that cells with a distance greater than 200m but less than or equal to 400m from Cell 1 and with a cell angle less than or equal to 60 degrees are regarded as neighboring cells of Cell 1. The same applies to other rows. If Cell 2 meets the corresponding conditions, Cell 2 can be regarded as a neighboring cell of Cell 1.

[0168] According to the cell coverage types of two cells, determine the corresponding distance threshold and angle threshold in Table 1, and then the neighboring cells of the cell can be determined.

[0169] However, for the above method for determining neighboring cells, the same set of threshold parameters is used for all cells to be planned, with low flexibility, unable to meet the actual needs of cells in different coverage scenarios, and unable to adapt well to the coverage scenarios. For scenarios with dense sites, there are more redundant neighboring cells planned, and for scenarios with sparse sites, there is a phenomenon of missed planning of neighboring cells.

[0170] Based on this, the embodiments of the present application provide a method for determining neighboring cells, adaptively determining corresponding neighboring cells for each cell, thereby improving the flexibility of neighboring cell planning to meet the actual needs of cells in different coverage scenarios. The solutions of the embodiments of the present application will be introduced below with reference to the accompanying drawings.

[0171] Figure 2 is a flowchart of the method for determining neighboring cells provided by the embodiments of the present application. As Figure 2 shown, the method includes:

[0172] S21, based on the engineering parameter information of the target cell, determine the reference coverage distance and candidate search area of the target cell.

[0173] The reference coverage distance of the target cell refers to the theoretical coverage distance of the target cell, indicating the coverage area of the target cell. And the candidate search area of the target cell is the area used for subsequent searching of neighboring cells. Based on the engineering parameter information of the target cell, the reference coverage distance and candidate search area of the target cell can be determined.

[0174] S22, based on the reference coverage distance, determine the search distance of the candidate search area.

[0175] After determining the reference coverage distance, the search distance of the candidate search area can be determined based on the reference coverage distance. The search distance is used to limit the search range in the candidate search area. Among them, there is a positive correlation between the search distance and the reference coverage distance. The larger the reference coverage distance, the larger the search distance, and the smaller the reference coverage distance, the smaller the search distance.

[0176] S23, based on the search distance, determine the neighboring cells of the target cell from the candidate search area.

[0177] After determining the search distance, the corresponding search range can be determined in the candidate search area based on the search distance, and cell search can be performed, so as to determine the neighboring cells of the target cell from the candidate search area.

[0178] In a possible implementation, the engineering parameter information of the target cell includes the downtilt angle of the target cell, the height of the site to which the target cell belongs, the center frequency of the target cell, and the azimuth angle of the target cell. Based on the above engineering parameter information, the reference coverage distance and the candidate search area of the target cell can be determined. The following will combine Figure 3 to introduce this process.

[0179] Figure 3 is the flowchart for determining the reference coverage distance and the candidate search area provided by the embodiment of the present application. As Figure 3 shown, it includes:

[0180] S31. Determine the first reference coverage distance of the target cell based on the downtilt angle of the target cell and the height of the site to which the target cell belongs.

[0181] The downtilt angle of the target cell is used to indicate the coverage direction of the target cell, and the height of the site to which the target cell belongs is the height of the site to which the target cell belongs. For specific examples, please refer to Figure 4 the examples.

[0182] Figure 4 is the schematic diagram for determining the first reference coverage distance provided by the embodiment of the present application. As Figure 4 shown, where point O is the location of the site to which the target cell belongs, point C is the projection of point O on the ground, and the length H of line segment CO is the height of the site to which the target cell belongs. Line segment OD represents the coverage direction of the target cell, and angle EOD represents the downtilt angle α of the target cell.

[0183] After obtaining the downtilt angle of the target cell and the height of the site to which the target cell belongs, the first reference coverage distance of the target cell can be determined. The specific calculation method can be referred to the following formula (1):

[0184]

[0185] Among them, Cover1 represents the first reference coverage distance, H represents the height of the site to which the target cell belongs, α represents the downtilt angle of the target cell, and tan is the tangent function.

[0186] S32. Determine the second reference coverage distance of the target cell based on the center frequency of the target cell.

[0187] From the dimension of the loss of radio waves propagating in free space, the second reference coverage distance of the target cell can be calculated. Among them, the free space loss formula of radio waves propagating in free space can be referred to the following formula (2):

[0188] Loss=20lg(F)+20lg(Cover2)+32.4 (2)

[0189] Among them, Loss is the loss value of radio waves propagating in free space, with the unit of dB, F represents the center frequency of the target cell, with the unit of MHz, and Cover2 represents the second reference coverage distance of the target cell, with the unit of km.

[0190] Generally, Loss can take the empirical value of 120 (which can be adjusted according to the situation). Substituting it into Equation (2), the second reference coverage distance Cover2 of the target cell can be obtained.

[0191] S33. Based on the first reference coverage distance and the second reference coverage distance, determine the reference coverage distance.

[0192] After obtaining the first reference coverage distance Cover1 and the second reference coverage distance Cover2, the reference coverage distance can be determined. Specifically, refer to the following Equation (3):

[0193] Cover = min(Cover1, Cover2) (3)

[0194] Among them, Cover represents the reference coverage distance, and min(Cover1, Cover2) represents taking the minimum value between the first reference coverage distance Cover1 and the second reference coverage distance Cover2.

[0195] S34. Based on the azimuth angle of the target cell, determine the candidate search area.

[0196] The candidate search area is the area for subsequent neighboring cell search, that is, the neighboring cells of the target cell are determined in the candidate search area subsequently.

[0197] In a possible implementation manner, after obtaining the azimuth angle of the target cell, first, based on the azimuth angle of the target cell, divide the coverage direction interval of the target cell to obtain the first coverage direction interval and the second coverage direction interval. Among them, the first coverage direction interval is the interval that does not include the direction where the azimuth angle of the target cell is located, and the second coverage direction interval is the interval that includes the direction where the azimuth angle of the target cell is located.

[0198] After obtaining the first coverage direction interval and the second coverage direction interval, based on the position of the target cell and the first coverage direction interval, determine the first candidate search area, and based on the position of the target cell and the second coverage direction interval, determine the second candidate search area. The candidate search area includes the first candidate search area and / or the second candidate search area.

[0199] The following combines Figure 5 Introduce the specific implementation process of the coverage direction interval division.

[0200] Figure 5 This is a schematic diagram for determining the candidate search area provided by the embodiment of the present application. AsFigure 5 As shown, the coverage direction interval of the target cell is an angle β formed centered on the azimuth angle of the target cell, and β = 125°.

[0201] The angle β is divided to obtain angle β1, angle β2, and angle β3. Among them, angle β1 is the left side lobe of 30°, and the angular range relative to the azimuth angle of the target cell is -62.5° to -32.5°; angle β2 is the forward 65°, and the angular range relative to the azimuth angle of the target cell is -32.5° to +32.5°; angle β3 is the right side lobe of 30°, and the angular range relative to the azimuth angle of the target cell is +32.5° to +62.5°.

[0202] Among them, the intervals of angle β1 and angle β3 do not include the direction interval where the azimuth angle of the target cell is located, so they belong to the first coverage direction interval; the interval of angle β2 includes the direction interval where the azimuth angle of the target cell is located, so it belongs to the second coverage direction interval.

[0203] For angle β1, taking the position of the target cell as the center of the circle, the sector area obtained with angle β1 as the central angle is the candidate search area corresponding to angle β1 (hereinafter referred to as quadrant 1); for angle β2, taking the position of the target cell as the center of the circle, the sector area obtained with angle β2 as the central angle is the candidate search area corresponding to angle β2 (hereinafter referred to as quadrant 2); for angle β3, taking the position of the target cell as the center of the circle, the sector area obtained with angle β3 as the central angle is the candidate search area corresponding to angle β3 (hereinafter referred to as quadrant 3). Among them, quadrant 1 and quadrant 3 belong to the first candidate search area, and quadrant 2 belongs to the second candidate search area.

[0204] In the above embodiment, in combination with Figures 3 to 5 introduced the implementation scheme for determining the reference coverage distance of the target cell and the candidate search area. Next, in combination with Figure 6 introduced the implementation scheme for determining the search distance of the candidate search area based on the reference coverage distance.

[0205] Figure 6 The flowchart for determining the search distance of the candidate search area based on the reference coverage distance provided by the embodiment of the present application is as Figure 6 shown, including:

[0206] S61, based on the reference coverage distance, determine a sub-candidate search area from the candidate search area.

[0207] In an embodiment of the present application, the sub-candidate search area is a sub-area of the candidate search area, and the sub-candidate search area can be determined from the candidate search area based on the reference coverage distance Cover. It should be satisfied that the distance between any position in the sub-candidate search area and the position of the target cell is less than or equal to the reference coverage distance Cover.

[0208] Taking the candidate search area Figure 5 as the first quadrant 1 of the candidate search area as an example, the corresponding sub-candidate search area is a sector area with the position O of the target cell as the center, the angle β1 as the central angle, and the reference coverage distance Cover as the radius.

[0209] Taking the candidate search area Figure 5 as the second quadrant 2 of the candidate search area as an example, the corresponding sub-candidate search area is a sector area with the position O of the target cell as the center, the angle β2 as the central angle, and the reference coverage distance Cover as the radius.

[0210] Taking the candidate search area Figure 5 as the third quadrant 3 of the candidate search area as an example, the corresponding sub-candidate search area is a sector area with the position O of the target cell as the center, the angle β3 as the central angle, and the reference coverage distance Cover as the radius.

[0211] S62, determine whether there is a target macro station in the sub-candidate search area that has the same frequency as the target cell.

[0212] After determining the sub-candidate search area, a search can be performed in the sub-candidate search area to search for whether there is a target macro station in the sub-candidate search area that has the same frequency as the target cell.

[0213] S63, determine the search distance based on whether there is a target macro station in the sub-candidate search area.

[0214] Specifically, first, based on whether there is a target macro station in the sub-candidate search area, determine the candidate search distance d, and then based on the candidate search distance, the reference coverage distance, and the preset radius coefficient, determine the search distance of the candidate search area.

[0215] Searching for whether there is a target macro station in the sub-candidate search area may have two results. The first result is that there is no target macro station in the sub-candidate search area that has the same frequency as the target cell, and the second result is that there is a target macro station in the sub-candidate search area that has the same frequency as the target cell. The following combines Figure 7 to introduce the implementation scheme for determining the candidate search distance for the above two different results.

[0216] Figure 7 is a schematic diagram for determining the candidate search distance provided by an embodiment of the present application, asFigure 7 As shown, three sub-candidate search areas of sector AOB, sector BOC, and sector COD are respectively exemplified, and O is the location of the target cell.

[0217] In the case where there is no target macro station in the sub-candidate search area, the reference coverage distance is determined as the candidate search distance, that is, d = Cover.

[0218] For the sub-candidate search area of sector COD, if no target macro station with the same frequency as the target cell is found in this area, the reference coverage distance is determined as the candidate search distance corresponding to the sub-candidate search area of sector COD, that is, Figure 7 d3 exemplified in

[0219] In the case where there is a target macro station in the sub-candidate search area, the distance between the target cell and the target macro station is determined as the candidate search distance.

[0220] For the sub-candidate search area of sector AOB, if a target macro station 71 with the same frequency as the target cell is found in this area, the distance between the target macro station 71 and the location of the target cell is determined as the candidate search distance corresponding to the sub-candidate search area of sector AOB, that is, Figure 7 d1 exemplified in

[0221] If there are multiple target macro stations, the target macro station with the shortest distance to the target cell is determined among the multiple target macro stations, and the distance between it and the target cell is determined as the candidate search distance.

[0222] For the sub-candidate search area of sector BOC, if target macro stations 72 and 73 with the same frequency as the target cell are found in this area, and the distance from target macro station 72 to the target cell is greater than the distance from target macro station 73 to the target cell, the distance between target macro station 73 and the location of the target cell is determined as the candidate search distance corresponding to the sub-candidate search area of sector BOC, that is, Figure 7 d2 exemplified in

[0223] After obtaining the candidate search distance, based on the candidate search distance, the reference coverage distance, and the preset radius coefficient, the search distance of the candidate search area can be determined.

[0224] Specifically, first determine the product of the candidate search distance and the preset radius coefficient, then compare this product with the reference coverage distance, and determine the search distance of the candidate search area based on the comparison result.

[0225] In the case where the product is less than or equal to the reference coverage distance, the product is determined as the search distance; in the case where the product is greater than the reference coverage distance, the reference coverage distance is determined as the search distance, that is:

[0226]

[0227] Wherein, R is the search distance, d is the candidate search distance, k is a preset radius coefficient, for example, it can be taken as or other suitable values, d*k is the product between the candidate search distance and the preset radius coefficient, and Cover is the reference coverage distance.

[0228] After determining the search distance of the candidate search area, the neighboring cells of the target cell can be determined from the candidate search area based on this search distance. The following combines Figure 8 to introduce this process.

[0229] Figure 8 is the flowchart for determining the neighboring cells of the target cell provided by the embodiment of the present application. As Figure 8 shown, it includes:

[0230] S81, based on the search distance, determine the target search area from the candidate search area.

[0231] In the embodiment of the present application, the target search area includes an inter-frequency target search area, an inter-system target search area, and a same-frequency target search area. Among them, the inter-frequency target search area is used to search for cells with different frequencies from the target cell as the neighboring cells of the target cell; the inter-system target search area is used to search for cells with different systems from the target cell as the neighboring cells of the target cell; the same-frequency target search area is used to search for cells with the same frequency as the target cell as the neighboring cells of the target cell.

[0232] In the embodiment of the present application, a cell with a different system from the target cell refers to a cell with a different communication system from the target cell. For example, if the communication system of the target cell is 5G, then a cell with a communication system of 4G belongs to a cell with a different system from the target cell. A cell with a different system from the target cell usually also has a different center frequency from the target cell. A cell with a different frequency from the target cell refers to a cell with a different center frequency from the target cell. A cell with the same frequency as the target cell refers to a cell with the same center frequency as the target cell. If a certain cell has the same frequency as the target cell, then the communication system of this cell is the same as that of the target cell.

[0233] Specifically, for the inter-frequency target search area, based on the search distance, the inter-frequency target search area can be determined from the candidate search area. Among them, the distance between any position in the inter-frequency target search area and the position of the target cell is less than or equal to the search distance.

[0234] For the heterogeneous system target search area, based on the search distance, the heterogeneous system target search area can be determined from the candidate search areas. Among them, the distance between any position in the heterogeneous system target search area and the position of the target cell is less than or equal to the search distance. The inter-frequency target search area and the heterogeneous system target search area can be the same or different.

[0235] Please refer to Figure 7 , for the candidate search area of quadrant 1, let the search distance be R1, then both the inter-frequency target search area and the heterogeneous system target search area can be a sector area with the position O of the target cell as the center, the angle β1 as the central angle, and R1 as the radius; for the candidate search area of quadrant 2, let the search distance be R2, then both the inter-frequency target search area and the heterogeneous system target search area can be a sector area with the position O of the target cell as the center, the angle β2 as the central angle, and R2 as the radius; for the candidate search area of quadrant 3, let the search distance be R3, then both the inter-frequency target search area and the heterogeneous system target search area can be a sector area with the position O of the target cell as the center, the angle β3 as the central angle, and R3 as the radius.

[0236] For the co-frequency target search area, the co-frequency target search area can be determined from the candidate search areas based on the search distance, or the co-frequency target search area can be determined from the candidate search areas based on the search distance and the reference coverage distance.

[0237] Specifically, the implementation method of determining the co-frequency target search area from the candidate search areas based on the search distance includes: when the candidate search area includes the first candidate search area, based on the search distance, determine the first co-frequency target search area from the first candidate search area, and the co-frequency target search area includes the first co-frequency target search area. Among them, the distance between any position in the first co-frequency target search area and the position of the target cell is less than or equal to the search distance.

[0238] Please refer to Figure 7 , the first candidate search area includes quadrant 1 and quadrant 3. For quadrant 1, let the search distance be R1, then the first co-frequency target search area can be a sector area with the position O of the target cell as the center, the angle β1 as the central angle, and R1 as the radius; for quadrant 3, let the search distance be R3, then the first co-frequency target search area can be a sector area with the position O of the target cell as the center, the angle β3 as the central angle, and R3 as the radius.

[0239] The implementation method of determining the co-frequency target search area from the candidate search areas based on the search distance and the reference coverage distance includes:

[0240] When the candidate search area includes a second candidate search area, a second same-frequency target search area is determined from the second candidate search area based on the search distance;

[0241] A third same-frequency target search area is determined from the second candidate search area based on the search distance and the reference coverage distance. The same-frequency target search area includes the second same-frequency target search area and the third same-frequency target search area.

[0242] For the second same-frequency target search area, the distance between any position in the second same-frequency target search area and the position of the target cell is less than or equal to the search distance. Please refer to Figure 7 , the second candidate search area includes quadrant 2. For quadrant 2, let the search distance be R2, then the second same-frequency target search area can be a sector area with the position O of the target cell as the center, the angle β2 as the central angle, and R2 as the radius.

[0243] For the third same-frequency target search area, after obtaining the search distance, the product of the search distance and a preset parameter is determined as the updated search distance. Then, the smaller value of the updated search distance and the reference coverage distance is determined as the target search distance. Furthermore, based on the target search distance, a third same-frequency target search area is determined from the second candidate search area. Among them, the distance between any position in the third same-frequency target search area and the position of the target cell is less than or equal to the target search distance.

[0244] The calculation formula for the target search distance can be referred to the following formula (5):

[0245] R’=min(k0*R,Cover) (5)

[0246] Wherein, R’ represents the target search distance; k0 represents a preset parameter, for example, it can take values of 2, 3 or other appropriate values; R represents the search distance; Cover represents the reference coverage distance; min(k0*R,Cover) represents taking the smaller value of k0*R and Cover.

[0247] Please refer to Figure 7 , the second candidate search area includes quadrant 2. For quadrant 2, taking k0 = 2 as an example, the corresponding target search distance is min(2*R2,Cover), then the third same-frequency target search area can be a sector area with the position O of the target cell as the center, the angle β2 as the central angle, and min(2*R2,Cover) as the radius.

[0248] S82. In the target search area, multiple candidate cells of a preset type are determined. The preset type includes in-building distribution cells, co-site cells of the target cell, or counter cells of the target cell.

[0249] After determining the target search area, the cells in the target search area can be searched, and among the cells in the target search area, multiple candidate cells of a preset type are determined.

[0250] The preset type includes in-building distribution cells, co-site cells of the target cell, or counter cells of the target cell. Among them, whether a cell belongs to an in-building distribution cell is determined by the attributes of the cell itself.

[0251] Whether a cell belongs to a co-site cell of the target cell is determined by the relationship between the longitude and latitude of the cell and the longitude and latitude of the target cell. A co-site cell refers to a cell sharing the same site, that is, a cell under the same base station. For any cell, if the longitude and latitude of the cell are the same as those of the target cell, then the cell belongs to the co-site cell of the target cell.

[0252] Whether a cell belongs to a counter cell of the target cell is determined by the relationship between the azimuth angle of the cell and the azimuth angle of the target cell.

[0253] For any cell, let the included angle between the direction where the azimuth angle of the cell is located and the direction where the azimuth angle of the target cell is located be γ. Then, under the condition that γ satisfies the following formula (6), it is determined that the cell belongs to the counter cell of the target cell; under the condition that γ does not satisfy the following formula (6), it is determined that the cell does not belong to the counter cell of the target cell:

[0254] 180° - γ0 ≤ |γ| ≤ 180° + γ0 (6)

[0255] Among them, γ0 is the azimuth angle deviation factor, and its value can be preset in advance. For example, it can be set to 65° or other appropriate values.

[0256] S83. Determine the neighboring cells of the target cell from multiple candidate cells.

[0257] Since the target search area includes an inter-frequency target search area, an inter-system target search area, and a same-frequency target search area, the above-mentioned multiple candidate cells include candidate cells that are in the inter-frequency target search area and have a different frequency from the target cell, candidate cells that are in the inter-system target search area and have a different system from the target cell, and candidate cells that are in the same-frequency target search area and have the same frequency as the target cell.

[0258] For the inter-frequency target search area, if the candidate search area corresponding to the inter-frequency target search area is the first candidate search area, then among the candidate cells included in the first candidate search area, the cells that are the counter cells and in-building distribution cells of the target cell are determined as the neighboring cells of the target cell; if the candidate search area corresponding to the inter-frequency target search area is the second candidate search area, then among the candidate cells included in the first candidate search area, the cells that are the co-site cells and in-building distribution cells of the target cell are determined as the neighboring cells of the target cell.

[0259] For the inter-system target search area, if the candidate search area corresponding to the inter-system target search area is the first candidate search area, then among the candidate cells included in the first candidate search area, the cells that are the counter cells and in-building distribution cells of the target cell are determined as the neighboring cells of the target cell; if the candidate search area corresponding to the inter-system target search area is the second candidate search area, then among the candidate cells included in the first candidate search area, the cells that are the co-site cells and in-building distribution cells of the target cell are determined as the neighboring cells of the target cell.

[0260] For the same-frequency target search area, if the same-frequency target search area includes the first same-frequency target search area, then among the candidate cells included in the first same-frequency target search area, the cells that are the counter cells and in-building distribution cells of the target cell are determined as the neighboring cells of the target cell; if the same-frequency target search area includes the second same-frequency target search area and the third same-frequency target search area, then among the candidate cells included in the second same-frequency target search area, the cells that are the co-site cells and in-building distribution cells of the target cell are determined as the neighboring cells of the target cell, and among the candidate cells included in the third same-frequency target search area, the cells that are the counter cells of the target cell are determined as the neighboring cells of the target cell.

[0261] The following Figure 9 is an example of this process.

[0262] Figure 9 is a schematic diagram for determining the neighboring cells of the target cell provided by the embodiment of the present application. As Figure 9 shown, it includes three candidate search areas: quadrant 1, quadrant 2, and quadrant 3. Among them, quadrant 1 and quadrant 3 are the first candidate search areas, and quadrant 2 is the second candidate search area.

[0263] As Figure 9 shown, for quadrant 1, the corresponding inter-frequency target search area and inter-system target search area are both fan-shaped areas with the position O of the target cell as the center, the angle β1 as the central angle, and the radius R1. Therefore, the cells within this area that are different in frequency or system from the target cell and belong to the counter cells or in-building distribution cells of the target cell are determined as the neighboring cells of the target cell.

[0264] For quadrant 2, the corresponding inter-frequency target search area and inter-system target search area are both sector areas centered at the location O of the target cell, with a central angle of β2 and a radius of R2. Therefore, the cells that are inter-frequency or inter-system with the target cell and belong to the co-site cells or in-building distribution cells of the target cell within this area are determined as the neighboring cells of the target cell.

[0265] For quadrant 3, the corresponding inter-frequency target search area and inter-system target search area are both sector areas centered at the location O of the target cell, with a central angle of β3 and a radius of R3. Therefore, the cells that are inter-frequency or inter-system with the target cell and belong to the opposite cells or in-building distribution cells of the target cell within this area are determined as the neighboring cells of the target cell.

[0266] For quadrant 1, the corresponding co-frequency target search area is a sector area centered at the location O of the target cell, with a central angle of β1 and a radius of R1. The cells that are co-frequency with the target cell and belong to the opposite cells or in-building distribution cells of the target cell within this area are determined as the neighboring cells of the target cell.

[0267] For quadrant 2, the corresponding co-frequency target search area includes the second co-frequency target search area and the third co-frequency target search area. The second co-frequency target search area is a sector area centered at the location O of the target cell, with a central angle of β2 and a radius of R2. The third co-frequency target search area is a sector area centered at the location O of the target cell, with a central angle of β2 and a radius of min(2*R2, Cover). Then, the cells that are co-frequency with the target cell and belong to the co-site cells or in-building distribution cells of the target cell within the second co-frequency target search area are determined as the neighboring cells of the target cell. The cells that are co-frequency with the target cell and belong to the opposite cells of the target cell within the third co-frequency target search area are determined as the neighboring cells of the target cell.

[0268] For quadrant 3, the corresponding co-frequency target search area is a sector area centered at the location O of the target cell, with a central angle of β3 and a radius of R3. The cells that are co-frequency with the target cell and belong to the opposite cells or in-building distribution cells of the target cell within this area are determined as the neighboring cells of the target cell.

[0269] After determining the neighboring cells of the target cell, the unidirectional neighboring cell relationship is updated to a bidirectional neighboring cell relationship. For example, if the target cell is cell 1 and the neighboring cell of the target cell is cell 2, after determining that the neighboring cell of cell 1 is cell 2, it is also necessary to determine cell 1 as the neighboring cell of cell 2.

[0270] In a possible implementation, there may be multiple neighboring cells of the target cell. Based on the distances between the target cell and each neighboring cell, the priorities of each neighboring cell are determined. Among them, the shorter the distance between the target cell and a neighboring cell, the higher the priority of the neighboring cell.

[0271] When the number of neighboring cells of the target cell is limited, some cells can be deleted from multiple neighboring cells based on the priorities of the neighboring cells, and the deleted cells are not used as neighboring cells of the target cell.

[0272] The method for determining neighboring cells provided in the embodiments of the present application first determines the reference coverage distance and the candidate search area of the target cell based on the engineering parameter information of the target cell, and determines the search distance of the candidate search area based on the reference coverage distance. Then, based on this search distance, neighboring cells of the target cell are determined from the candidate search area. In the solution of the embodiments of the present application, since the corresponding reference coverage distance and candidate search area are determined based on the engineering parameter information of the target cell, both the reference coverage distance and the candidate search area are related to the engineering parameter information of the target cell. Therefore, the neighboring cells finally determined in the candidate search area are also related to the engineering parameter information of the target cell. If the engineering parameter information of the target cell is different, the determined neighboring cells are also correspondingly different. Compared with the implementation method of determining neighboring cells of the target cell by presetting threshold parameters, it has higher flexibility and can meet the actual needs of cells in different coverage scenarios.

[0273] Figure 10 The following is a schematic structural diagram of an electronic device provided in the embodiments of the present application. As Figure 10 shown, the electronic device includes a memory 1020, a transceiver 1000, and a processor 1010, where:

The bus architecture can also link together various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art, so they will not be further described herein. The bus interface provides an interface. The transceiver 1000 can be multiple components, that is, including a transmitter and a receiver, and provides a unit for communicating with various other devices on the transmission medium, and these transmission mediums include wireless channels, wired channels, optical fiber cables, and other transmission mediums. The processor 1010 is responsible for managing the bus architecture and general processing, and the memory 1020 can store the data used by the processor 1010 when executing operations.

[0280] Optionally, the processor 1010 can be a central processing unit (CPU), an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or a complex programmable logic device (CPLD), and the processor can also adopt a multi-core architecture.

[0281] The processor is used to execute any method provided by the embodiments of the present application according to the obtained executable instructions by calling the computer program stored in the memory. The processor and the memory can also be physically separated.

[0282] In a possible implementation manner, the engineering parameter information includes the down-tilt angle of the target cell, the height of the site to which the target cell belongs, the center frequency of the target cell, and the azimuth angle of the target cell.
