Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method, device and electronic equipment for grouping cells within a base station coverage area. Background Art

[0002] Currently, with the continuous development of communication technology, the number of cells within the coverage area of ​​the same base station has also increased. Since the network loads of different cells within the coverage area of ​​the same base station are different, and the base station allocates the same network resources to each cell, the signal quality of communication signals in different cells within the coverage area of ​​the base station varies greatly.

[0003] Therefore, in order to balance the signal quality of communication signals of various cells within the coverage area of ​​the same base station, it is necessary to allocate network resources to each cell according to the network load of different cells within the coverage area of ​​the base station so as to optimize the network resource allocation plan of the network resources of the base station.

[0004] In the related technology, for each base station, relevant staff can group the above cells in pairs according to the geographical location, number or communication signal frequency band used by each cell in the coverage area of ​​the base station, and calculate the load difference between the two cells in each group of cells. Then, based on the above load difference, adjust the network resources allocated to each cell.

[0005] However, in the above-mentioned related technologies, for each base station, the cells located in the coverage area of ​​the base station are grouped in pairs manually, which makes it difficult to ensure the rationality of the grouping. Furthermore, the network resource allocation scheme finally adopted may be less effective, resulting in large differences in the signal quality of communication signals of different cells located in the coverage area of ​​the base station.

[0093] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0094] In the related technology, for each base station, relevant staff can group the above cells in pairs according to the geographical location, number or communication signal frequency band used by each cell within the coverage area of ​​the base station, and calculate the load difference between the two cells in each group of cells. Then, based on the above load difference, adjust the network resources allocated to each cell.

[0095] However, in the above-mentioned related technologies, for each base station, each cell within the coverage area of ​​the base station is grouped into pairs manually, which makes it difficult to ensure the rationality of the grouping. Furthermore, the network resource allocation scheme ultimately adopted may be less effective, resulting in large differences in the signal quality of communication signals in different cells within the coverage area of ​​the base station.

[0096] In order to solve the above technical problem, an embodiment of the present invention provides a method for grouping cells within a base station coverage area.

[0097] This method can be applied to various application scenarios that require grouping of cells within the base station coverage area. For example, the cells within the existing base station coverage area can be grouped to reallocate network resources; the cells within the coverage area of ​​a newly built base station can also be grouped to determine a network resource allocation plan.

[0098] Among them, the technical solution provided by the embodiment of the present invention can be applied to various types of base stations, for example, the base station can be a 5G base station or a 4G base station; and the cells in the base station coverage area can be residential areas, shopping malls and other types of cells that comply with the cell division rules in the field of communication technology. At the same time, the method can be applied to various electronic devices and electronic device clusters that can obtain relevant information about base stations and cells in the base station coverage area, such as servers that provide services for base stations, communication system management servers, and data processing devices independent of base stations and communication systems, hereinafter referred to as electronic devices.

[0099] A method for grouping cells within a base station coverage area provided by an embodiment of the present invention may include the following steps:

[0100] Selecting a target frequency band from communication signal frequency bands used by various cells within a target coverage area of ​​a target base station;

[0101] Based on the azimuth and preset angle of each target cell, determine the range of the sector based on the azimuth of the target cell as the sector range of the target cell; wherein the straight line corresponding to the azimuth of each target cell is the angle bisector of the central angle corresponding to the sector range of the target cell; the target cell is: a cell among the cells that uses the target frequency band;

[0102] For each target cell, candidate cells whose azimuths are within the sector range of the target cell and the target cell are grouped together to obtain various cell combinations; wherein the candidate cells are cells other than the target cell among the various cells.

[0103] As can be seen from the above, by applying the solution provided by the embodiment of the present invention, when grouping cells within the base station coverage area, the target frequency band is first selected from the communication signal frequency bands used by the cells within the target coverage area of ​​the target base station. Next, the cells within the coverage area of ​​the target base station that use the target frequency band are determined as target cells, and the cells within the coverage area of ​​the target base station other than the target cells are determined as candidate cells. Furthermore, based on the azimuth and preset angle of each target cell, the range of the sector based on the azimuth of the target cell is determined as the sector range of the target cell. Afterwards, for each target cell, the candidate cells whose azimuth is within the sector range of the target cell and the target cell are divided into a group to obtain various cell combinations.

[0104] Based on this, the scheme provided by the embodiment of the present invention is applied, and for each cell within the target coverage area of ​​each target base station, each cell is grouped according to the communication signal frequency band used by each cell and the azimuth of each cell. In this way, in the above-mentioned cell grouping process, the usage of the communication signal frequency band of each cell and the positional relationship between each cell are fully considered, so that when the network load state is determined by grouping the cells within the target coverage area of ​​the target base station and the network resource allocation scheme of the network resources of the target base station is optimized, the rationality of the cell grouping can be improved, and then, the effect of the network resource allocation scheme finally adopted is improved, and the difference in signal quality of communication signals of different cells within the target coverage area of ​​the target base station is reduced.

[0105] A method for grouping cells within a base station coverage area provided in an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0106] Figure 1 A schematic diagram of a flow chart of a method for grouping cells within a base station coverage area provided in an embodiment of the present invention, such as Figure 1 As shown, the method may include the following steps S101-S103.

[0107] S101: Selecting a target frequency band from communication signal frequency bands used by various cells within a target coverage area of ​​a target base station;

[0108] When grouping cells within the base station coverage area, the target base station is first determined. Then, based on the location information of the target base station, the target coverage area of ​​the target base station can be determined. Thus, each cell located within the target coverage area can be determined. The determined cells are the cells to be grouped.

[0109] The above-determined cells may be all cells within the target coverage area of ​​the target base station, or may be part of the cells within the target coverage area of ​​the target base station.

[0110] Furthermore, the communication signal frequency bands used by each cell within the target coverage area of ​​the target base station may be determined, and one frequency band may be selected from the determined communication signal frequency bands as the target frequency band.

[0111] Among them, the embodiment of the present invention does not specifically limit the method for selecting the above-mentioned target frequency band. Any method that can select the target frequency band from the communication signal frequency bands used by each cell within the target coverage area of ​​the target base station falls within the protection scope of the embodiment of the present invention.

[0112] Optionally, in a specific implementation, the above step S101 may include the following steps 11-12:

[0113] Step 11: Determine the communication signal frequency band used by each cell within the target coverage area of ​​the target base station;

[0114] Step 12: Based on the determined opening time of each communication signal frequency band, determine the target frequency band from the determined communication signal frequency bands.

[0115] In this specific implementation, after determining the communication signal frequency bands used by each cell within the target coverage area of ​​the target base station, the target frequency band can be determined from the determined communication signal frequency bands according to the order of engineering construction.

[0116] Optionally, among the communication signal frequency bands used by various cells within the target coverage area of ​​the target base station, the communication signal frequency band with the earliest opening time is used as the target frequency band;

[0117] Optionally, among the communication signal frequency bands used by various cells within the target coverage area of ​​the target base station, the communication signal frequency band with the latest opening time is used as the target frequency band;

[0118] For example, the communication signal frequency bands used by each cell within the target coverage area of ​​the target base station include LTE (Long Term Evolution, long-term evolution of general mobile communication technology) 800M, LTE1.8G, LTE2.1G and 5GNR (5G New Radio, 5G mobile network) 3.5G. Among the communication signal frequency bands used by the above-mentioned cells, the communication signal frequency band with the earliest opening time is taken as the target frequency band, and the determined target frequency band is LTE1.8G; among the communication signal frequency bands used by the above-mentioned cells, the communication signal frequency band with the latest opening time is taken as the target frequency band, and the determined target frequency band is 5GNR3.5G.

[0119] Optionally, in a specific implementation, the above step S101 may include the following steps 21-23:

[0120] Step 21: Determine the communication signal frequency band used by each cell within the target coverage area of ​​the target base station;

[0121] Step 22: Counting the number of cells using each determined communication signal frequency band;

[0122] Step 23: Determine the target frequency band based on the various numbers obtained by counting.

[0123] In this specific implementation method, after determining the communication signal frequency band used by each cell within the target coverage area of ​​the target base station, the number of cells using each determined communication signal frequency band within the above-mentioned cells can be counted. In this way, based on the statistically obtained numbers, a frequency band can be selected from the communication signal frequency bands determined above as the target frequency band.

[0124] Optionally, a communication signal frequency band corresponding to a maximum value among the statistically obtained quantities is determined as a target frequency band;

[0125] After obtaining by counting the number of cells using each communication signal frequency band determined above in each cell within the coverage area of ​​the target base station, the maximum value among the obtained numbers can be determined, and there is only one maximum value. It can be determined that among the cells within the coverage area of ​​the target base station, the number of cells using the communication signal frequency band corresponding to the maximum value is the largest. Therefore, the communication signal frequency band corresponding to the maximum value can be determined as the target frequency band.

[0126] For example, the communication signal frequency bands used by each cell within the target coverage area of ​​the target base station include LTE800M, LTE1.8G, LTE2.1G and 5GNR3.5G, and among the cells within the target coverage area of ​​the target base station, the number of cells using LTE800M is 3, the number of cells using LTE1.8G is 4, the number of cells using LTE2.1G is 1, and the number of cells using 5GNR3.5G is 2, then LTE1.8G can be determined as the target frequency band.

[0127] Optionally, based on the activation time, a target frequency band is determined from a plurality of communication signal frequency bands corresponding to a plurality of maximum values ​​among the respective numbers obtained by counting.

[0128] After obtaining by statistics the number of cells using each communication signal frequency band determined above in each cell within the coverage area of ​​the target base station, the maximum value among the obtained numbers can be determined. If there are multiple maximum values, it can be determined that the number of cells using the communication signal frequency band corresponding to each maximum value in each cell within the coverage area of ​​the target base station is the same. Thus, the communication signal frequency band corresponding to each of the above maximum values ​​can be determined, and a frequency band can be selected from the multiple communication signal frequency bands determined based on the activation time as the target frequency band.

[0129] For example, the communication signal frequency bands used by each cell within the target coverage area of ​​the target base station include LTE800M, LTE1.8G, LTE2.1G and 5GNR3.5G, and among the cells within the target coverage area of ​​the target base station, there are 3 cells using LTE800M, 3 cells using LTE1.8G, 1 cell using LTE2.1G, and 2 cells using 5GNR3.5G. According to the activation time, the earliest activated LTE1.8G can be determined as the target frequency band, or the latest activated 5GNR3.5G can be determined as the target frequency band.

[0130] Optionally, the communication signal frequency bands used by each cell within the target coverage area of ​​the target base station are determined, and a frequency band is selected from the determined communication signal frequency bands in a user-defined order as the target frequency band.

[0131] S102: Based on the azimuth angle of each target cell and a preset angle, determine a sector range based on the azimuth angle of the target cell as the sector range of the target cell;

[0132] The straight line corresponding to the azimuth angle of each target cell is the angle bisector of the central angle corresponding to the sector range of the target cell; the target cell is: a cell using the target frequency band among the cells.

[0133] The azimuth of the cell refers to the angle of the cell relative to the true north direction when the true north direction is 0 degrees and the clockwise direction is the positive direction.

[0134] After the target frequency band is determined, each cell located in the target coverage area of ​​the target base station and each cell using the target frequency band may be used as a target cell.

[0135] Since the positions of the various cells within the target coverage area of ​​the target base station are determined, the azimuth of each target cell can be determined.

[0136] Furthermore, for each target cell, based on the azimuth angle and preset angle of the target cell, the straight line corresponding to the azimuth angle of the target cell is used as the angular bisector of the central angle corresponding to the sector range of the target cell, and the preset angles are added in the clockwise and counterclockwise directions of the azimuth angle of the target cell respectively, so that the sector range of the target cell can be determined.

[0137] The preset angle may be set according to actual requirements in practical applications, for example, 10 degrees, 25 degrees, etc., which is not specifically limited in the embodiments of the present invention.

[0138] Optionally, the preset angle is greater than 0 degrees and not greater than 32.5 degrees, that is, the preset angle is not zero degrees and does not exceed half of the half-power angle of the base station antenna.

[0139] S103: for each target cell, grouping candidate cells whose azimuth angles are within the sector range of the target cell and the target cell into a group to obtain cell combinations;

[0140] The candidate cells are cells other than the target cell among all the cells.

[0141] The cells other than the target cell in the target coverage area of ​​the target base station are selected as candidate cells, that is, the cells in the target coverage area of ​​the target base station that use communication signal frequency bands other than the target frequency band are selected as candidate cells. At the same time, the geographical location of each candidate cell is determined, that is, the azimuth of each candidate cell is also determined.

[0142] For each target cell, candidate cells whose azimuths are within the sector range of the target cell and the target cell are grouped together, so that a cell combination corresponding to the target cell can be obtained, and further each cell combination can be obtained.

[0143] Optionally, for each target cell, the angle difference between the azimuth of the target cell and the azimuth of each candidate cell is calculated respectively, and the angle difference is compared with the preset angle. Thus, if the angle difference is not greater than the preset angle, the candidate cell edge can be grouped together with the target cell.

[0144] That is, for each target cell, if there is no candidate cell whose azimuth angle difference with the azimuth angle of the target cell is not greater than the preset angle, the target cell can be regarded as a cell combination.

[0145] Different target cells belong to different cell combinations, and each candidate cell may belong to one cell combination or to multiple cell combinations.

[0146] In this way, for each target cell, a cell combination including the target cell can be obtained, and each cell combination may include at least one candidate cell or may not include a candidate cell.

[0147] That is, for each target cell, if there is no candidate cell whose azimuth angle is within the sector range of the target cell, the target cell can be regarded as a cell combination.

[0148] As can be seen from the above, by applying the solution provided by the embodiment of the present invention, for each cell within the target coverage area of ​​each target base station, each cell is grouped according to the communication signal frequency band used by each cell and the azimuth of each cell. In this way, in the above cell grouping process, the usage of the communication signal frequency band of each cell and the positional relationship between each cell are fully considered, so that when the network load state is determined by grouping the cells within the target coverage area of ​​the target base station and the network resource allocation scheme of the network resources of the target base station is optimized, the rationality of the cell grouping can be improved, and then, the effect of the network resource allocation scheme finally adopted can be improved, and the difference in signal quality of communication signals of different cells within the target coverage area of ​​the target base station can be reduced.

[0149] For example, in order to facilitate understanding of the specific implementation of the above S103, the following is combined with Figure 2 Provide specific instructions.

[0150] Among them, Figure 2 As shown, B is the target cell, A and C are candidate cells, AZ is a preset angle, and OB is used to represent the azimuth of the target cell B.

[0151] Furthermore, by increasing the azimuth angle of the target cell B by a preset angle AZ in the clockwise direction and a preset angle AZ in the counterclockwise direction, a sector-shaped area OPT can be obtained. The azimuth angle range corresponding to the central angle of the sector-shaped area OPT is the sector range of the target cell B.

[0152] Furthermore, since the azimuth of candidate cell A is located within the sector area OPT, while the azimuth of candidate cell C is not within the sector area OPT, it can be explained that the azimuth of candidate cell A is located within the sector range of target cell B, while the azimuth of candidate cell B is not within the sector range of target cell B. Therefore, candidate cell A and target cell B can be grouped together to obtain a cell combination including candidate cell A and target cell B.

[0153] Optionally, in a specific implementation, such as Figure 3 As shown, the above step S102, the step of determining the sector range of each target cell based on the azimuth angle and the preset angle of each target cell, may include the following steps S1021-S1023:

[0154] S1021: For each target cell, determine the azimuth of the target cell;

[0155] S1022: For each target cell, determine a first azimuth angle obtained by increasing the azimuth angle of the target cell by a preset angle in a clockwise direction, and a second azimuth angle obtained by decreasing the azimuth angle of the target cell by a preset angle in a counterclockwise direction;

[0156] S1023: For each target cell, an angle range including the azimuth of the target cell, which is formed by the determined first azimuth and the second azimuth, is determined as a sector range based on the azimuth of the target cell.

[0157] In this specific implementation, for each target cell, the azimuth of the target cell may be first determined. Then, the azimuth of the target cell may be increased by a preset angle in a clockwise direction, and the azimuth obtained after the increase is used as a first azimuth; and the azimuth of the target cell may be increased by a preset angle in a counterclockwise direction, and the azimuth obtained after the increase is used as a second azimuth.

[0158] In this way, the angle range consisting of the first azimuth angle and the second azimuth angle and including the azimuth angle of the target cell can be determined as the sector range of the target cell.

[0159] Among them, for each target cell, the specific value of the sector range of the target cell may be different according to the different numerical relationships among the azimuth angle, the preset angle and 360 degrees of the target cell. Thus, the sector range of each target cell may be one of the following situations.

[0160] Case 1: For each target cell, the azimuth angle a of the target cell is not less than the preset angle b, and the sum of the azimuth angle a of the target cell and the preset angle b is not greater than 360 degrees.

[0161] Then the first azimuth angle is: a+b, and the second azimuth angle is: ab, so the sector range of the target cell is [ab, a+b];

[0162] Case 2: For each target cell, the azimuth angle a of the target cell is not less than the preset angle b, and the sum of the azimuth angle a of the target cell and the preset angle b is greater than 360 degrees;

[0163] Then the first azimuth angle is: a+b-360 degrees, and the second azimuth angle is: ab. Thus, the sector range of the target cell is: the union of [ab, 360] and [0, a+b-360 degrees].

[0164] Case 3: For each target cell, the azimuth angle a of the target cell is smaller than the preset angle b, and the sum of the azimuth angle a of the target cell and the preset angle b is not greater than 360 degrees.

[0165] Then the first azimuth angle is: a+b, and the second azimuth angle is: a-b+360 degrees. Thus, the sector range of the target cell is: the union of [a-b+360, 360] and [0, a+b].

[0166] Case 4: For each target cell, the azimuth angle a of the target cell is smaller than the preset angle b, and the sum of the azimuth angle a of the target cell and the preset angle b is greater than 360 degrees.

[0167] Then the first azimuth angle is: a+b-360 degrees, and the second azimuth angle is: a-b+360 degrees. Therefore, the sector range of the target cell is: the union of [a-b+360 degrees, 360] and [0, a+b-360].

[0168] Optionally, in a specific implementation, such as Figure 4 As shown, a method for grouping cells within a base station coverage area provided in an embodiment of the present invention may further include the following steps S104-S106:

[0169] S104: for each cell combination, determine whether there is a same communication signal frequency band among the communication signal frequency bands used by the cells in the cell combination; if yes, execute S105; otherwise, execute S106;

[0170] S105: outputting designated information for prompting the existence of co-channel interference;

[0171] S106: Determine the network load status of each cell in the cell combination, and perform a response operation that matches the network load status of each cell in the cell combination.

[0172] In this specific implementation, after obtaining the above-mentioned cell combinations, for each cell combination, the communication signal frequency bands used by the cells in the cell combination can be determined, and then, it is determined whether there are the same communication signal frequency bands among the determined communication signal frequency bands. In other words, it is determined whether there are multiple cells in the cell combination using the same communication signal frequency band.

[0173] Among them, if the above-mentioned determination result is existence, that is, there are multiple cells in the cell combination using the same communication signal frequency band, then it can be explained that co-channel interference will occur in the cell combination, and thus, it can be explained that there is an error in the distribution planning of the communication signal frequency band of the cell combination, and thus, designated information for prompting the existence of co-channel interference can be output; wherein, the designated information can be various types of information such as text information and voice information.

[0174] If the above determination result is non-existent, that is, there are no multiple cells in the cell combination using the same communication signal frequency band, then the network load status of each cell in the cell combination can be further determined, thereby performing a response operation that matches the network load status of each cell in the cell combination.

[0175] Optionally, in a specific implementation, in the above step S106, executing a response operation matching the network load status of each cell in the cell group may include the following steps 31-39:

[0176] Step 31: If the network load states of the cells in the cell combination are the same and are all in the first category state or the second category state, outputting the first prompt information;

[0177] The first prompt information is used to prompt that there are idle network resources in the sector occupied by the cell combination in the target coverage area, the first state indicates that the network load of the cell meets the first condition, the second state indicates that the network load of the cell meets the second condition, and the second condition is not lower than the first condition;

[0178] Step 32: If the network load states of the cells in the cell combination are the same and are all in the third category state, determine whether the designated frequency band includes all used frequency bands; if so, execute step 33; otherwise, execute step 34;

[0179] The designated frequency band is: the communication signal frequency band used by each cell in the cell combination, the used frequency band is: the communication signal frequency band used by each cell within the target coverage area, and the third type of status indicates that the network load of the cell meets the third type of condition, and the third type of condition is greater than the second type of condition;

[0180] Step 33: outputting second prompt information; wherein the second prompt information is used to prompt to increase the network resources of each cell in the cell combination;

[0181] Step 34: determine whether the angle difference between the azimuth of the designated cell and the target cell is less than the designated angle; if so, execute step 35; otherwise, output a third prompt message; wherein the third prompt message is used to prompt the missing frequency band in the cell combination to be expanded;

[0182] The designated cell is a cell whose communication signal frequency band is a missing frequency band, the missing frequency band is a used frequency band not included in the designated frequency band, and the designated angle is greater than the preset angle;

[0183] Step 35: adding a preset angle, and returning to the above step S102, determining the sector range of each target cell based on the azimuth angle and the preset angle of each target cell;

[0184] Step 36: if the network load states of the cells in the cell combination are different, and there are third-category cells whose network load states are the third-category states and first-category cells whose network load states are the first-category states, output fourth prompt information;

[0185] The fourth prompt information is used to prompt that the network resources of each cell in the cell combination are evenly distributed;

[0186] Step 37: if the network load states of the cells in the cell combination are different, and there are third-category cells whose network load states are the third-category states and second-category cells whose network load states are the second-category states, then output the fourth prompt information;

[0187] Step 38: If the network load states of the cells in the cell combination are different, and there are third-category cells with a network load state of the third category, first-category cells, and second-category cells with a network load state of the second category, then output the fourth prompt information;

[0188] Step 39: if the network load states of the cells in the cell combination are different, and there are fourth-category cells and first-category cells whose network load states are the fourth-category states, output the fourth prompt information;

[0189] Among them, the fourth type of cells are cells that do not meet the first type of conditions, the second type of conditions, and the third type of conditions.

[0190] According to the above steps 31-39, in this specific implementation method, the network load state of each cell can be determined as the first state, the second state, the third state and the fourth state according to the relationship between the network load of each cell and the first condition, the second condition and the third condition, and each cell combination can be divided into six combinations according to the network load state of each cell within the cell combination.

[0191] Among them, the third type of conditions is greater than the second type of conditions, and the second type of conditions is not less than the first type of conditions. In addition, the first type of conditions, the second type of conditions, and the third type of conditions can be set according to actual needs.

[0192] Thus, for each cell, there are four situations as follows:

[0193] Case 1: If the network load of a cell meets the above first-category conditions, the network load state of the cell can be considered to be a first-category state, and such cells are called first-category cells;

[0194] The second case: if the network load of the cell meets the above second condition, the network load state of the cell can be considered as the second state, and such cells are called second-class cells;

[0195] The third case: If the network load of the cell meets the third condition, the network load state of the cell can be considered as the third state, and such cells are called third-class cells;

[0196] Fourth case: If the network load of the cell does not meet the above first, second and third conditions, the network load state of the cell can be considered as the fourth state, and such cells are called fourth-class cells;

[0197] Furthermore, for each cell combination, there are the following six states:

[0198] State 1: The network load states of the cells in the cell group are the same and are all in the first or second state;

[0199] State 2: If the network load states of the cells in the cell combination are the same and are all in the third category state;

[0200] State 3: If the network load states of the cells in the cell combination are different, and there are third-category cells with a network load state of the third category and first-category cells with a network load state of the first category,

[0201] State 4: If the network load states of the cells in the cell combination are different, and there are third-category cells whose network load states are the third-category state and second-category cells whose network load states are the second-category state,

[0202] State 5: If the network load states of the cells in the cell combination are different, and there are third-category cells with a network load state of the third category, first-category cells, and second-category cells with a network load state of the second category,

[0203] State six: if the network load states of the cells in the cell combination are different, and there are fourth-category cells whose network load states are the fourth-category states and first-category cells.

[0204] For each cell combination, when it is determined that the network load state of each cell in the cell combination belongs to any of the above situations, a corresponding response operation can be performed. There are also six response operations corresponding to the above six states:

[0205] Response operation one: if the network load state of each cell in the cell combination is the above state one, output first prompt information for prompting that there are idle network resources in the sector occupied by the cell combination in the target coverage area;

[0206] Response operation 2: if the network load state of each cell in the cell combination is the above state 2, determine whether the communication signal frequency bands used by each cell in the cell combination include all the communication signal frequency bands used by each cell in the target coverage area;

[0207] If yes, output second prompt information for prompting to increase network resources of each cell in the cell combination; illustratively, add a base station around the cells in the cell combination.

[0208] Otherwise, determine whether the angle difference between the azimuth angles of the designated cell and the target cell is less than the designated angle; wherein the designated cell is: a cell whose communication signal frequency band used is a missing frequency band; the missing frequency band is: a used frequency band not included in the designated frequency band; the designated frequency band is: the communication signal frequency band used by each cell in the cell combination; the designated angle is greater than the preset angle and can be set according to actual needs.

[0209] When the above-mentioned angle is less than the specified angle, the above-mentioned preset angle is increased, and the sector range of each target cell is re-determined, that is, returning to the above-mentioned step S102, based on the azimuth angle and the preset angle of each target cell, the sector range of each target cell is determined; at this time, the preset angle used is the increased preset angle.

[0210] When the angle is not less than the specified angle, outputting third prompt information for prompting to expand the missing frequency band in the cell combination;

[0211] Response operation three: if the network load state of each cell in the cell combination is the above state three, output fourth prompt information for prompting to evenly allocate network resources of each cell in the cell combination;

[0212] Response operation four: if the network load state of each cell in the cell combination is the above state four, output fourth prompt information for prompting to evenly allocate network resources of each cell in the cell combination;

[0213] Response operation five: if the network load state of each cell in the cell combination is the above state five, output fourth prompt information for prompting to evenly allocate network resources of each cell in the cell combination;

[0214] Response operation six: if the network load status of each cell in the cell combination is the above-mentioned status six, output fourth prompt information for prompting to evenly distribute the network resources of each cell in the cell combination.

[0215] For example, in order to facilitate understanding of the specific implementation of the above-mentioned response operation based on the network load status of each cell combination, the following is combined with Figure 5 Provide specific instructions.

[0216] like Figure 5 As shown in the figure, F represents the frequency band, L represents the network load; the zero state represents the first type of state, the idle state represents the second type of state, the busy state represents the third type of state, and the normal state represents the fourth type of state.

[0217] “Same-frequency interference exists in cells within the sector group and needs to be checked” means: when the same frequency band exists in the communication signal frequency bands used by the cells within the cell group, a prompt message is output to prompt that there is same-frequency interference;

[0218] “The load in the sector is low, and it is recommended to activate resources” means: when the network load status of each cell in the cell combination is the above status, the prompt information output is used to prompt that there are idle network resources in the sector occupied by the cell combination in the target coverage area; wherein, the so-called resource activation means: the network resources of the idle cells and the zero cells in the cell combination are allocated to the busy cells in other cell combinations, so as to make full use of the above idle network resources;

[0219] "Insufficient sector frequency resources" means that the communication signal frequency bands used by the cells in the cell combination do not include all the communication signal frequency bands used by the cells in the target coverage area;

[0220] “Missing frequency cell expansion plan” is prompt information outputted to prompt capacity expansion of missing frequency band cells in the cell combination when the network load status of each cell in the cell combination is the above-mentioned status 2;

[0221] "Load balancing optimization suggestion for network resources A to B" is a prompt information output when the network load status of each cell in the cell combination is the above-mentioned state three, state four, state five and state six, which is used to prompt the balanced distribution of network resources of each cell in the cell combination.

[0222] When the cell combination is a combination of cell A and cell B, based on the network load status of cell A and cell B, the process of performing a response operation on the cell combination is as follows:

[0223] First, determine whether the communication signal frequency band FA used by cell A and the communication signal frequency band FB used by cell B are the same; if FA is the same as FB, output a prompt message for prompting "there is co-frequency interference in the cells within the sector group and needs to be checked";

[0224] If FA is different from FB, determine whether the network load state LA of cell A and the network load state LB of cell B are the same;

[0225] If LA is the same as LB, traverse all cells in the cell group. When the network load of each cell is idle or zero, output a prompt message for prompting "the load in the sector is low, it is recommended to activate resources"; when the network load of each cell is busy and the sector frequency resources are not full, it is prompted to check whether the azimuth of the cell outside the sector group is reasonable, and output a prompt message for prompting "missing frequency cell expansion plan";

[0226] If FA and FB are different, when LA is busy and LB is idle or zero, or when LA is normal and LB is zero, a prompt message for "load balancing optimization suggestion for network resource A to B" is output;

[0227] When LA and LB are outside the above situations, the network load in the cell combination is normal.

[0228] Optionally, in a specific implementation, the network load includes: traffic and PRB (Physical Resource Block) utilization, and the above-mentioned determination of the network load state of each cell in the cell combination may include the following steps 41-44:

[0229] Step 41: for each cell in the cell group, if the network load state of the cell meets the first condition, determining that the network load state of the cell is the first state;

[0230] The first type of conditions include: the traffic volume in a specified period is not higher than a first traffic volume threshold, and the PRB utilization rate is not higher than a first utilization rate threshold;

[0231] Step 42: for each cell in the cell group, if the network load state of the cell satisfies the second condition, determining that the network load state of the cell is the second condition;

[0232] Among them, the second type of conditions include: in each time period divided according to the specified time granularity included in each time range within the specified period, there is a time period in which the traffic is lower than the second traffic threshold and not lower than the first traffic threshold, and the PRB utilization is lower than the second utilization threshold and not lower than the first utilization threshold; the second traffic threshold is greater than the first traffic threshold, and the second utilization threshold is greater than the first utilization threshold;

[0233] Step 43: for each cell in the cell group, if the network load state of the cell satisfies the third type condition, determining that the network load state of the cell is the third type state;

[0234] Among them, the third type of conditions include: in each time period divided according to the specified time granularity included in the preset number of time ranges within the specified period, there is a time period in which the traffic is higher than the third traffic threshold and the PRB utilization is higher than the third utilization threshold; the third traffic threshold is not less than the second traffic threshold, and the third utilization threshold is not less than the second utilization threshold;

[0235] Step 44: For each cell in the cell combination, if the network load state of the cell does not meet the first condition, the second condition and the third condition, then determine that the network load state of the cell is the fourth condition.

[0236] In this specific implementation, the network load status of each cell can be divided into four categories based on the traffic and PRB utilization of the cell within a preset period, namely, the first category, the second category, the third category and the fourth category.

[0237] The first type of conditions include: within a specified period, the total flow is not higher than the first flow threshold L1, and the PRB utilization is not higher than the first utilization threshold P1;

[0238] Optionally, the first traffic threshold L1 may be zero, and correspondingly, the first type of conditions may include: within a specified period, the total traffic is zero and the PRB utilization is also zero.

[0239] The second type of conditions includes: within each time range within the specified period and divided according to the specified time granularity, there is a time period, during which the traffic is lower than the second traffic threshold L2 and not lower than the first traffic threshold L1, and the PRB utilization is lower than the second utilization threshold P2 and not lower than the first utilization threshold P1, that is, Formula 1 and Formula 2 are satisfied.

[0240] Among them, formula 1 is:

[0241] L1≤L <L2

[0242] Among them, formula 2 is:

[0243] P1≤P <P2

[0244] The third type of conditions includes: within each time period divided according to the specified time granularity and included in a preset number of time ranges within the specified period, there is a time period in which the traffic is higher than the third traffic threshold L3 and the PRB utilization is higher than the third utilization threshold P3, that is, Formula 3 and Formula 4 are satisfied.

[0245] Among them, formula three is:

[0246] L3 <L

[0247] Among them, formula 4 is:

[0248] P3 <P

[0249] The above-mentioned specified period, preset number of time ranges and specified time granularity can be set according to actual needs. For example, the specified period can be set to 7 days, the preset number of time ranges can be set to 5 days, and the specified time granularity can be set to 1 hour.

[0250] Among them, the numerical relationship among the first flow threshold L1, the second flow threshold L2 and the third flow threshold L3 satisfies Formula 5.

[0251] Among them, formula five is:

[0252] L1 <L2≤L3

[0253] The numerical relationship among the first utilization threshold value P1, the second utilization threshold value P2 and the third utilization threshold value P3 satisfies Formula 6.

[0254] Among them, formula six is:

[0255] P1 <P2≤P3

[0256] For example, in order to facilitate understanding of the above network load status classification method, the following is an explanation in conjunction with the specific embodiment shown in Table 1 below.

[0257] Table 1

[0258]

[0259] As shown in Table 1, the coverage of the target base station range includes 10 cells, and the communication signal frequency bands used by each cell include: LTE1.8G, LTE2.1G, LTE800M and 5GNR3.5G. At the same time, the number of cells using LTE1.8G is 3, the number of cells using LTE2.1G is 3, the number of cells using LTE800M is 1, and the number of cells using 5GNR3.5G is 3. When determining the target frequency band, since there are 3 cells used for LTE1.8G, LTE2.1G and 5GNR, the earliest opened frequency band is determined as the target frequency band, that is, LTE1.8G is used as the target frequency band. Furthermore, Figure 6 As shown, the cells 2, 6 and 10 using LTE 1.8G are used as target cells, and the other cells are used as candidate cells, and the cells are grouped. The preset angle is 30 degrees.

[0260] The azimuth angles of the target cell 2 are 0 degrees, and the sector angle range corresponding to the target cell 2 is the union of [330, 360] and [0, 30]. Then, a cell combination including the cell 1 and the cell 2 is determined as the first combination;

[0261] The azimuth angles of the target cell 6 are 120 degrees, and the sector angle range corresponding to the target cell 6 is [90, 150]. Then, a cell combination including the cell 5 and the cell 6 is determined as the second combination;

[0262] The azimuth angles of the target cells 10 are 240 degrees, and the sector angle range corresponding to the target cells 10 is [210, 270]. Further, a cell combination including the cells 8, 9 and 10 is determined as the third combination.

[0263] In Table 1, threshold B is a time period in which the flow rate is higher than the third flow rate threshold L3 and the PRB utilization rate is higher than the third utilization rate threshold P3 in each time period divided according to the specified time granularity included in the preset number of time ranges within the specified period; threshold F is a time period in which the flow rate is lower than the second flow rate threshold L2 and the PRB utilization rate is lower than the second utilization rate threshold P2 in each time period divided according to the specified time granularity included in each time range within the specified period. The above-mentioned specified period is set to 7 days, the above-mentioned preset number of time ranges is set to 4 days, and the above-mentioned specified time granularity is set to 1 hour.

[0264] Based on threshold B and threshold F, the network load status of the cell is classified.

[0265] like Figure 7 As shown, the first condition is the load zero state, represented by "zero"; the second condition is the load idle state, represented by "idle"; the third condition is the load busy state, represented by "busy", and the fourth condition is the load normal state, represented by "normal".

[0266] And, if Figure 7 As shown, the LTE800M frequency band (band5) is represented as "5"; the LTE1.8G frequency band (band3) is represented as "3"; the LTE2.1G frequency band (band1) is represented as "1"; and the 5GNR 3.5G frequency band (n78) is represented as "N".

[0267] Therefore, in combination with the frequency band used by each cell and the network load status, the FL (FREQ and LOAD) value of each cell can be determined, as shown in Table 1. And based on the FL value of each cell, corresponding operations are performed for each determined cell combination.

[0268] Both cells in the first cell combination are busy. It is necessary to check whether the azimuth angle of cell 3 is reasonable and whether the sector range needs to be adjusted. Then, a load balancing analysis can be performed to output a reasonable capacity expansion plan.

[0269] The two cells in the second cell combination can be load balanced and optimized, and the balance optimization of busy and idle cells is required.

[0270] The load resources of the three cells in the third cell combination are normal, and no optimization operation is performed.
