[0002] In communication technology, neighbor cell handover is used to ensure the smooth transition of services for user mobile phones in the mobile network. Each sector of the base station needs to determine the neighbor cell relationships used for neighbor cell handover.

[0003] Currently, the neighbor relationships between sectors are determined solely by the distance between base stations. This results in issues such as missing effective neighbor cells and redundant neighbor cells, making the neighbor relationships inaccurate. Summary of the Invention

[0028] The corrected distance of each sector interval is weighted by the weight corresponding to the corrected angle between each sector interval to obtain the adjusted distance of each sector interval.

[0029] As an optional implementation, determining the target neighboring cell corresponding to each sector based on the adjusted distance between each sector includes:

[0030] Determine the candidate neighbor cells for each sector; the adjusted distance between the candidate neighbor cells of each sector and the distance between each sector is within the preset distance range;

Because the initial distance between each sector is adjusted based on the azimuth, scene, frequency band, and coverage type of each sector, the adjusted distance between each sector reflects the coverage direction and coverage distance between sectors, rather than just the distance between the base stations to which the sector belongs. Therefore, by determining the neighbor cell corresponding to each sector based on the adjusted distance between each sector, invalid neighbor cells can be excluded, valid neighbor cells can be included, and the target neighbor cell for each sector can be accurately determined.

[0058] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0059] The prior art involved in this application will be described in detail and analyzed below.

[0060] Currently, for each sector of a base station, neighboring sectors are added sequentially based on the distance between the sectors and the base stations, from smallest to largest. For example, sectors within 1KM, 3KM, and 5KM of the base station of a sector are added as neighboring sectors in turn. While this method can quickly determine the neighboring relationships of a sector, it has the following problems: invalid neighboring sectors within the distance range are added, while valid neighboring sectors outside the distance range are missed.

[0061] In summary, existing technologies suffer from inaccurate neighbor cell relationships.

[0062] In response to the problems in existing technologies, the inventors conducted creative research to determine more accurate neighbor cell relationships. In addition to considering the distance between base stations where sectors are located, the coverage direction of sectors also needs to be taken into account when determining neighbor cell relationships. Sectors that are far away but face the sector's coverage direction are identified as neighbor cells, while sectors that are close but face away from the sector's coverage direction are not identified as neighbor cells. This avoids redundancy and omissions in neighbor cell relationships and determines more accurate neighbor cell relationships.

[0063] Therefore, the inventors propose the technical solution of this application, which involves obtaining the azimuth, scene, frequency band, and coverage type of multiple sectors within a preset area; adjusting the initial distance between each sector based on the azimuth, scene, frequency band, and coverage type of each sector to obtain the adjusted distance between each sector; the initial distance being the distance between the base stations to which the sector belongs; and determining the target neighboring cells corresponding to each sector based on the adjusted distance between each sector. Since the initial distance between each sector is adjusted based on the azimuth, scene, frequency band, and coverage type of each sector, the adjusted distance between each sector can reflect the coverage direction and coverage distance between the sectors, rather than just the distance between the base stations to which the sectors belong. Furthermore, by determining the neighboring cells corresponding to each sector based on the adjusted distance between each sector, invalid neighboring cells can be excluded, valid neighboring cells can be included, and the target neighboring cells corresponding to each sector can be accurately determined.

[0064] The neighbor cell determination method, apparatus, device, and storage medium provided in this application aim to solve the above-mentioned technical problems of the prior art. The technical solutions of this application and how they solve the aforementioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0065] The network architecture and application scenarios of the neighbor cell determination method provided in the embodiments of this application will be described below. When the following description refers to the accompanying drawings, unless otherwise indicated, the same data in different drawings represent the same or similar elements.

[0066] Figure 1 This is a network architecture diagram corresponding to the application scenario of the neighbor cell determination method provided in the embodiments of this application. For example... Figure 1 As shown in the figure, the network architecture corresponding to an application scenario provided in this application embodiment includes: electronic device 10 and multiple base stations. Figure 1 The diagram shows a first base station 11 and a second base station 12. The first base station 11 includes a first sector 111, a second sector 112 and a third sector 113, and the second base station 12 includes a fourth sector 121, a fifth sector 122 and a sixth sector 123.

[0067] Electronic device 10 acquires the azimuth, scene, frequency band, and coverage type of each sector in the preset area 13, for example... Figure 1 As shown, the electronic device acquires the azimuth, scene, frequency band and coverage type of the first sector 111, the second sector 112, the third sector 113, the fourth sector 121, the fifth sector 122 and the sixth sector 123.

[0068] Electronic device 10 adjusts the initial distance between each sector based on the azimuth, scene, frequency band, and coverage type of each sector to obtain the adjusted distance between each sector. The initial distance is the distance between the base stations to which the sector belongs, for example... Figure 1 As shown, the initial distance between the first sector 111 and the second sector 112 is 0, and the initial distance between the first sector 111 and the fourth sector 121 is the distance between the first base station 11 and the second base station 12.

[0069] The electronic device 10 determines the target neighboring cells corresponding to each sector based on the adjusted distance between each sector. For example, the target neighboring cells corresponding to the first sector 111 are determined to include the second sector 112, the third sector 113, and the fifth sector 122.

[0071] Therefore, optionally, the aforementioned base station can be a base station (BTS) and / or base station controller in GSM or CDMA, a base station (NodeB, NB) and / or radio network controller (RNC) in WCDMA, an evolved Node B (eNB or eNodeB) in LTE, a relay station or access point, or a base station (gNB) in future 5G networks, etc., which are not limited herein.

[0072] The embodiments of this application will now be described with reference to the accompanying drawings. The embodiments described below do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0073] Example 1

[0074] Figure 2 This is a flowchart illustrating the neighbor cell determination method provided in Embodiment 1 of this application. Figure 2 As shown, the executing entity of this application is a neighbor cell determination device, which is located in an electronic device. The neighbor cell determination method provided in this embodiment includes steps 201 to 203.

[0075] Step 201: Obtain the azimuth, scene, frequency band and coverage type of multiple sectors within the preset area.

[0076] In this embodiment, the preset area can be the area where the sector whose neighbor relationship needs to be determined is located, for example, within 5KM or 10KM of the sector whose neighbor relationship needs to be determined.

[0077] Azimuth is a parameter describing the orientation of an antenna in a mobile communication network. With true north as 0 degrees, and rotating clockwise 360 ​​degrees back to true north, the azimuth of a sector refers to the angle traversed when rotating clockwise from true north to align with the plane containing that sector's antenna. For example, for a three-sector base station, the azimuths of the three sectors could be 0 degrees, 120 degrees, and 240 degrees, respectively.

[0078] The scenario is determined by the area where the base station is located and the number of users. For example, the scenario can include densely populated urban areas, general urban areas, and rural areas.

[0079] A frequency band refers to the frequency band used by a sector antenna, which can include low frequency, mid frequency, and high frequency. Low frequency bands can include, for example, the 900MHz band corresponding to 904-909MHz and 949-954MHz, while high frequency bands can include, for example, the N78 band in 5G corresponding to 3400-3500MHz and 3500-3600MHz, and the N79 band corresponding to 4800-4900MHz, etc.

[0080] Coverage type refers to the coverage type of the sector antenna, which can include outdoor stations and indoor stations.

[0081] The initial distance between sectors is the straight-line distance between the base stations to which each sector belongs.

[0082] In this embodiment, the engineering parameters of each base station can be obtained from the network management system, site verification, and daily maintenance information of each base station within a preset area. This allows for the acquisition of the azimuth, scene, frequency band, and coverage type of each sector within the preset area. The engineering parameters of the base station may include the cell name, cell number, latitude and longitude, azimuth, frequency band, scene, and coverage type of the sector. The cell number is the unique identifier of a mobile network sector.

[0083] Step 202: Adjust the initial distance between each sector according to the azimuth, scene, frequency band and coverage type of each sector to obtain the adjusted distance between each sector; the initial distance is the distance between the base stations to which the sector belongs.

[0084] In this embodiment, the offset distance of each sector can be determined based on the scene, frequency band, and coverage type. When the scene and coverage type are the same, the offset distance of high-frequency band sectors is greater than that of low-frequency band sectors. When the frequency band and coverage type are the same, the offset distance of rural scene sectors is the largest, followed by general urban scene sectors, and the offset distance of densely populated urban scene sectors is the smallest. When the scene and frequency band are the same, the offset coefficient of outdoor station sectors is greater than or equal to that of indoor station sectors.

[0085] In this embodiment, each sector can be offset along its azimuth direction by its respective offset distance, and the adjusted distance between each sector can be calculated based on the offset sectors. For example, if sector A has an azimuth of 0 degrees and an offset distance of 0.5 km, and sector B has an azimuth of 180 degrees and an offset distance of 0.3 km, then adjusting the initial distance between sector A and sector B can be done by offsetting sector A 0.5 km northward and adjusting sector B 0.3 km southward. If the initial distance between sector A and sector B is 3 km, then the adjusted distance between sector A and sector B is 3 + 0.5 + 0.3 = 3.8 km.

[0086] Step 203: Determine the target neighboring cell corresponding to each sector based on the adjusted distance between each sector.

[0087] In this embodiment, the target neighboring cells corresponding to each sector can be determined in ascending order of the adjusted distances between each sector. Here, the number of target neighboring cells corresponding to each sector can be a preset number and can be unequal.

[0088] For example, the adjusted distances between sector A and sectors B, C, D and E are 3.8 km, 3 km, 5 km and 1 km respectively, and the preset number of target neighboring sectors of sector A is 3. Then sector E, sector C and sector B can be determined as target neighboring sectors of sector A.

[0089] The neighbor cell determination method provided in this embodiment obtains the azimuth, scene, frequency band, and coverage type of multiple sectors within a preset area; adjusts the initial distance between each sector based on the azimuth, scene, frequency band, and coverage type of each sector to obtain the adjusted distance between each sector; the initial distance is the distance between the base stations to which the sector belongs; and determines the target neighbor cell corresponding to each sector based on the adjusted distance between each sector. Because the initial distance between each sector is adjusted based on the azimuth, scene, frequency band, and coverage type of each sector, the adjusted distance between each sector reflects the coverage direction and coverage distance between sectors, rather than just the distance between the base stations to which the sector belongs. Therefore, by determining the neighbor cell corresponding to each sector based on the adjusted distance between each sector, invalid neighbor cells can be excluded, valid neighbor cells can be included, and the target neighbor cell for each sector can be accurately determined.

[0090] As an optional implementation, step 202 is further refined to include steps 301 to 304.

[0091] Step 301: Obtain the initial latitude and longitude of each sector; the initial latitude and longitude are the latitude and longitude of the base station to which the sector belongs.

[0092] In this embodiment, the initial latitude and longitude of the sector includes initial longitude and initial latitude. The initial longitude is the longitude of the base station to which the sector belongs, and the initial latitude is the latitude of the base station to which the sector belongs.

[0093] Step 302: Determine the offset coefficient of each sector based on the scene, frequency band, and coverage type of each sector.

[0094] In this embodiment, different scenarios, frequency bands, and coverage types can correspond to different preset coefficients. The sector offset coefficient can be the average of the preset coefficients corresponding to the sector's scenario, frequency band, and coverage type.

[0095] For example, sector A is located in a densely populated urban area, uses a high-frequency band, and has an outdoor station coverage type. Sector B is located in a general urban area, uses a low-frequency band, and has an outdoor station coverage type.

[0096] The coefficients are as follows: 0.2 for densely populated urban areas, 0.25 for general urban areas, 0.2 for high-frequency bands, 0.1 for low-frequency bands, and 0.2 for outdoor stations. Therefore, the offset coefficient for sector A is (0.2 + 0.2 + 0.2) / 3 = 0.2, and the offset coefficient for sector B is (0.25 + 0.1 + 0.2) / 3 ≈ 0.18.

[0097] As an optional implementation, step 302 is further refined to include steps 3021 to 3022.

[0098] Step 3021: Based on the scene, frequency band, and coverage type of each sector, query the offset coefficient corresponding to each sector in the preset mapping relationship; the preset mapping relationship includes: the mapping relationship between the scene, frequency band, and coverage type of the sector and the preset coefficient.

[0099] Step 3022: The preset coefficients that have a mapping relationship with the scene, frequency band and coverage type of each sector are determined as the offset coefficients of each sector.

[0100] In this embodiment, the offset coefficient is mainly affected by the frequency band, scene, and coverage type, with the frequency band having the greatest impact, followed by the scene, and the coverage type having the least impact. The stronger the penetration capability of the frequency band, the larger the offset coefficient. For example, the preset mapping relationship can be shown in Table 1 below, but this embodiment does not limit it.

[0101] Table 1 Preset Mapping Relationships

[0102]

[0103] As shown in Table 1, when the coverage type of the sector is an outdoor station and the scenario is a dense urban area, the offset coefficient can be mapped to between 0.1 and 0.2 according to different frequency bands. Furthermore, the lower the frequency band of the sector, the smaller the offset coefficient, and the higher the frequency band, the larger the offset coefficient.

[0104] When the sector coverage type is an outdoor station and the scenario is a general urban area, the offset coefficient can be mapped to between 0.1 and 0.25 according to different frequency bands. Furthermore, the lower the frequency band of the sector, the smaller the offset coefficient, and the higher the frequency band, the larger the offset coefficient.

[0105] When the sector coverage type is an outdoor station and the scenario is rural, the offset coefficient can be mapped to between 0.15 and 0.25 according to different frequency bands. Furthermore, the lower the frequency band of the sector, the smaller the offset coefficient, and the higher the frequency band, the larger the offset coefficient.

[0106] When the coverage type of a sector is an indoor station, the offset coefficient can be mapped to between 0.1 and 0.2 according to different frequency bands, regardless of the scenario. Furthermore, the lower the frequency band of the sector, the smaller the offset coefficient, and the higher the frequency band, the larger the offset coefficient.

[0107] The neighbor cell determination method provided in this embodiment queries the offset coefficient corresponding to each sector in a preset mapping relationship based on the scene, frequency band, and coverage type of each sector. The preset mapping relationship includes the mapping relationship between the scene, frequency band, and coverage type of the sector and preset coefficients. The preset coefficients that have a mapping relationship with the scene, frequency band, and coverage type of each sector are determined as the offset coefficients of each sector. Since the offset coefficients corresponding to each sector are queried in the preset mapping relationship, the offset coefficients corresponding to each sector can be quickly determined, thereby improving the efficiency of determining the target neighbor cells of each sector.

[0108] Step 303: Based on the azimuth and offset coefficient of each sector, correct the initial latitude and longitude of each sector to obtain the corrected latitude and longitude of each sector.

[0109] As an optional implementation, step 303 is further refined to include step 3031.

[0110] Step 3031: Calculate the corrected longitude and corrected latitude of each sector using the following formula to obtain the corrected longitude and latitude of each sector:

[0111]

[0112] Where x′ is the corrected latitude, y′ is the corrected latitude, x is the initial longitude, y is the initial latitude, k is the offset coefficient, and α is the azimuth. Here, 111 is in km, and the azimuth α can be in radians (e.g., π / 3) or degrees (e.g., 120°). Therefore, the above formula can also be expressed as:

[0113]

[0114] The neighbor cell determination method provided in this embodiment uses a formula. The corrected longitude and corrected latitude of each sector can be calculated quickly.

[0115] Step 304: Determine the adjusted distance between each sector based on the corrected latitude and longitude of each sector.

[0116] As an optional implementation, step 304 can be further refined to include steps 401 to 402.

[0117] Step 401: Calculate the corrected distance between each sector based on the corrected latitude and longitude of each sector.

[0118] In this embodiment, the corrected latitude and longitude of any two sectors can be substituted into the semi-versus formula, and the calculated value can be determined as the corrected distance between the sectors.

[0119] For example, if the corrected latitude and longitude of sector A is (x1, y1) and the corrected latitude and longitude of sector B is (x2, y2), then the corrected distance Distance′(A, B) between sector A and sector B can be calculated using the following formula:

[0120]

[0121]

[0122] Among them, R EARTH The radius is the Earth's radius.

[0123] Step 402: Determine the corrected distance as the adjusted distance between each sector.

[0124] The neighbor cell determination method provided in this embodiment calculates the corrected distance between each sector based on the corrected latitude and longitude of each sector; the corrected distance is then determined as the adjusted distance between each sector. Since the corrected distance between each sector can be obtained by directly substituting the corrected latitude and longitude of each sector into the formula, and then the corrected distance is determined as the adjusted distance, the adjusted distance between each sector can be calculated quickly. Therefore, the target neighbor cell corresponding to each sector can be determined more accurately through the adjusted distance between each sector.

[0125] The neighbor cell determination method provided in this embodiment obtains the initial latitude and longitude of each sector; the initial latitude and longitude are the latitude and longitude of the base station to which the sector belongs; the offset coefficient of each sector is determined according to the scene, frequency band, and coverage type of each sector; the initial latitude and longitude of each sector is corrected according to the azimuth and offset coefficient of each sector to obtain the corrected latitude and longitude of each sector; and the adjusted distance between each sector is determined according to the corrected latitude and longitude of each sector. Since the corrected latitude and longitude of each sector is obtained by correcting the initial latitude and longitude of each sector, the adjusted distance between each sector can be determined quickly and accurately by using the corrected latitude and longitude of each sector.

[0126] Example 2

[0127] Figure 3 This is a flowchart illustrating the neighbor cell determination method provided in Embodiment 2 of this application. Figure 4A This is a schematic diagram of a distribution where the corrected included angle between the two sector intervals is 180 degrees, according to Embodiment 2 of this application. Figure 4B This is a schematic diagram illustrating another distribution scenario where the corrected included angle between the two sector intervals is 180 degrees, according to Embodiment 2 of this application. Figure 3As shown, the neighbor cell determination method provided in this embodiment is based on Embodiment 1, and step 304 is refined. Step 304 is refined to include steps 501 to 504.

[0128] Step 501: Calculate the corrected distance between each sector based on the corrected latitude and longitude of each sector.

[0129] In this embodiment, the corrected distance between each sector can be calculated using the same method as in step 401.

[0130] Step 502: Calculate the corrected angle between each sector based on the corrected latitude, longitude and azimuth of each sector.

[0131] In this embodiment, the corrected angle refers to the angle between the antennas of each sector.

[0132] For example, the corrected latitude and longitude of sector A is (x1, y1), the corrected latitude and longitude of sector B is (x2, y2), and the azimuth of sector A is... The initial angle between sector A and sector B is Then the corrected angle between sector A and sector B It can be done through formula The calculation can also be performed using the following formula:

[0133]

[0134] Where abs is the absolute value function. SIGN is the natural number judgment function, SIGN(x) equals -1 when x is negative, equals 1 when x is positive, and equals 0 when x is 0. ATAN is the arctangent function.

[0135] In this embodiment, it can be understood that the sector antenna has directivity. Directivity refers to the relationship between the relative value of the antenna radiation field and the spatial direction under the condition of the same distance r in the far field. The antenna radiation pattern is used to reflect the relationship between the relative value of the antenna radiation field and the spatial direction. The antenna radiation pattern usually has two or more lobes, of which the lobe with the largest radiation intensity is called the main lobe, and the remaining lobes are called side lobes or side lobes. The side lobe in the opposite direction to the main lobe is called the back lobe.

[0136] like Figure 4A and Figure 4B As shown, the arrow indicates the azimuth direction of the sector antenna, which is also the direction of the main lobe of the sector antenna. When the corrected angle between sector A and sector B is 180 degrees, sector A and sector B have the following... Figure 4A and Figure 4B The two distribution scenarios shown are, in Figure 4A and Figure 4BIn the two cases shown, the initial distance between sector A and sector B is equal, but the corrected distance between sector A and sector B is not equal. Figure 4A In the scenario shown, the corrected distance between sector A and sector B is less than the initial distance between sector A and sector B. Figure 4B In the scenario shown, the corrected distance between sector A and sector B is greater than the initial distance between them. Therefore, correcting the latitude and longitude and the corrected distance can eliminate the problem of inaccurate identification of target neighboring cells due to sector coverage direction, thereby improving the accuracy of the identified target neighboring cells.

[0137] Step 503: Obtain the weights corresponding to the corrected angles between each sector. When the corrected angle is [0, π], the corresponding weight is proportional to the corrected angle. When the corrected angle is [π, 2π], the corresponding weight is inversely proportional to the corrected angle. The weight corresponding to the corrected angle is greater than 1. Furthermore, when the corrected angles θ and β between the same sector and any two sector intervals satisfy (θ+β) / 2=π, the weights corresponding to θ and β are equal, where θ∈[0, π] and β∈[π, 2π].

[0138] In this embodiment, the weight k corresponding to the corrected angle ω can be determined by the following formula:

[0139] k=1, ω∈[0°, 60°]∪[300°, 360°];

[0140] k=1+μ1sinω,ω∈[60°,90°]∪[270°,300°];

[0141] k=1+μ2sinω,ω∈[90°, 270°];

[0142] Where μ1 can be 0.1 and μ2 can be 0.2.

[0143] In this embodiment, the weights corresponding to each correction angle can also be determined by other formulas, such as formulas including cosine function, step function, etc. It is only necessary to ensure that when the correction angles θ and β between the same sector and any two sectors satisfy (θ+β) / 2=π, the weights corresponding to θ and β are equal, where θ∈[0,π] and β∈[π,2π].

[0144] Step 504: Use the weights corresponding to the corrected angles of each sector interval to weight the corrected distances of the corresponding sector intervals to obtain the adjusted distances of each sector interval.

[0145] In this embodiment, the weights corresponding to the corrected angles between each sector are used to eliminate the influence of antenna sidelobes on the target neighboring cells of the determined sector. By weighting the corrected distances between sectors with different weights, the adjusted distances between each sector can prioritize the addition of neighboring cells in the main coverage direction of the sector, followed by sidelobes, and add the fewest in the back direction, thus fully simulating the antenna coverage model. This allows for a more accurate determination of the target neighboring cells of each sector.

[0146] Optionally, in addition to the method described above for determining the adjusted distance between each sector, other methods can be used to weight the corrected distance between sectors, as long as the weighted adjusted distance matches the directivity of the antenna coverage. For example, the method in this embodiment can be used so that the larger the angle between the two sector antennas, the larger the adjusted distance; other methods can also be used so that the smaller the angle between the two sector antennas, the smaller the adjusted distance. This embodiment does not limit this approach.

[0147] The neighbor cell determination method provided in this embodiment calculates the corrected distance between each sector based on the corrected latitude and longitude of each sector; calculates the corrected angle between each sector based on the corrected latitude, longitude and azimuth of each sector; obtains the weight corresponding to the corrected angle between each sector; when the corrected angle is [0, π], the corresponding weight is proportional to the corrected angle; when the corrected angle is [π, 2π], the corresponding weight is inversely proportional to the corrected angle; the weight corresponding to the corrected angle is greater than 1; and when the corrected angles θ and β between the same sector and any two sector intervals satisfy (θ+β) / 2=π, the weights corresponding to θ and β are equal, where θ∈[0, π] and β∈[π, 2π]; and uses the weight corresponding to the corrected angle between each sector interval to weight the corrected distance of the corresponding sector interval to obtain the adjusted distance of each sector interval. By weighting the corrected distances between each sector according to the corrected angle of each sector, the adjusted distances between each sector can be determined, which makes the distances between each sector match the antenna coverage direction. Therefore, the adjusted distances between each sector can be used to determine the target neighboring cells of each sector more accurately.

[0148] Example 3

[0149] Figure 5 This is a flowchart illustrating the neighbor cell determination method provided in Embodiment 3 of this application. Figure 6 This is a schematic diagram of the target neighboring cells of sector Cell1 determined according to the neighboring cell determination method provided in Embodiment 3 of this application. Figure 5 As shown, the neighbor cell determination method provided in this embodiment is based on any of the above-mentioned Embodiment 2, and the step 203 "determine the target neighbor cell corresponding to each sector according to the adjusted distance between each sector" is refined. The refined step 203 includes steps 601 to 602.

[0150] Step 601: Determine the candidate neighboring cells for each sector; the adjusted distance between the candidate neighboring cells of each sector and the other sectors is within a preset distance range.

[0151] In this embodiment, for any given sector, sectors within a preset area whose adjusted distance to that sector is within a preset distance range are identified as candidate neighboring sectors of that sector. For example, the preset distance range can be less than 4 km.

[0152] For example, the adjusted distances between sector A and sectors B, C, D, and E are 3.8 km, 3 km, 5 km, and 1 km, respectively. With a preset distance range of 0 to 4 km, the candidate neighboring sectors of sector A are sector B, sector C, and sector E.

[0153] Step 602: Select the first preset number of candidate neighboring cells from each sector, whose adjusted distances to each sector are in ascending order, as the target neighboring cells.

[0154] In this embodiment, since the scene, frequency band and coverage type of each sector are different, the number of target neighboring cells required may also be different. Therefore, for each sector, there can be a preset number of target neighboring cells. Among the candidate neighboring cells of the sector, the neighboring cells with the smaller adjusted distance to the sector are determined as the target neighboring cells of the sector first, thereby ensuring that the determined target neighboring cells do not miss any valid neighboring cells and do not have any invalid neighboring cells.

[0155] The neighbor cell determination method provided in this embodiment determines candidate neighbor cells for each sector; the adjusted distance between the candidate neighbor cells of each sector and the inter-sectoral distances is within a preset distance range; and a first preset number of candidate neighbor cells in each sector, whose adjusted distances to the inter-sectoral distances are from smallest to largest, are determined as target neighbor cells. Since candidate neighbor cells with smaller adjusted distances are determined as target neighbor cells for a sector, and the adjusted distances are adjusted according to the azimuth, scene, frequency band, and coverage type of each sector, it ensures that the determined target neighbor cells do not miss any valid neighbor cells and do not contain any invalid neighbor cells, thus determining more accurate target neighbor cells for each sector.

[0156] For example, such as Figure 6 As shown, in the preset area 14, the target neighboring cells of sector Cell-1 are determined to include: Cell-1, Cell-2, Cell-3, Cell-4, Cell-5, Cell-6, Cell-7, Cell-8, Cell-9, Cell-10, Cell-11, Cell-12, Cell-13, Cell-14, Cell-15, Cell-16, Cell-17, and Cell-18.

[0157] As an optional implementation, based on Embodiment 3, the candidate neighboring regions include: candidate neighboring regions of the same type and candidate neighboring regions of different types, and the target neighboring regions include: target neighboring regions of the same type and target neighboring regions of different types. Furthermore, steps 601 and 602 are refined, with step 601 refined to include steps 6011 to 6012, and step 602 refined to include steps 6021 to 6022.

[0158] Step 6011: The sector with the same coverage type as the candidate neighbor cell is identified as the same type of candidate neighbor cell.

[0159] Step 6012: Sectors with different coverage types from candidate neighboring cells are identified as heterogeneous candidate neighboring cells.

[0160] In this embodiment, for any sector in the preset area, among the multiple candidate neighboring sectors of the sector, the sector with the same coverage type as the sector is determined as the same type of candidate neighboring sector, and the sector with a different coverage type is determined as the different type of candidate neighboring sector.

[0161] Step 6021: Among the candidate neighboring cells of the same type, the second preset number of candidate neighboring cells of the same type with the adjusted distance between each sector from smallest to largest are determined as the target neighboring cells of the same type.

[0162] Step 6022: Among the heterogeneous candidate neighboring cells, the third preset number of heterogeneous candidate neighboring cells whose adjusted distances to each sector are from smallest to largest are determined as heterogeneous target neighboring cells.

[0163] In this embodiment, for any sector within a preset area, based on the data of target neighboring cells of various coverage types that can be added to that sector, the sector with the closest adjusted distance to that sector among the candidate neighboring cells of the same type is determined as the target neighboring cell of that sector. The number of target neighboring cells is a second preset number. For example, the number of outdoor station neighboring cells added to outdoor station neighboring cells can be between 42 and 50, the number of outdoor station neighboring cells added to indoor station neighboring cells can be between 16 and 24, and the number of indoor station neighboring cells added to indoor station neighboring cells can be between 12 and 18.

[0164] The neighbor cell determination method provided in this embodiment includes candidate neighbor cells of the same type and candidate neighbor cells of different types; target neighbor cells include target neighbor cells of the same type and target neighbor cells of different types. The method involves determining candidate neighbor cells of the same type as those of each sector, identifying them as candidate neighbor cells of the same type; identifying candidate neighbor cells of different types as candidate neighbor cells of different types; identifying a second preset number of candidate neighbor cells of the same type with each sector whose adjusted distances are from smallest to largest as target neighbor cells of the same type; and identifying a third preset number of candidate neighbor cells of different types with each sector whose adjusted distances are from smallest to largest as target neighbor cells of different types. Because it can determine target neighbor cells of the same type as each sector and neighbor cells of the same type but different types, and can control the number of neighbor relationships between sectors of different coverage types, it can meet different application scenarios.
