Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
A base station is an interface device for a mobile device to access the internet. One base station may correspond to one or more sectors, and each sector corresponds to a fixed signal radiation direction.
In a possible application scenario, when the number of communication network users in a certain cell increases, the corresponding communication activity increases, which may cause the base station corresponding to the cell to work in an overload state in some time periods. The base station in overload operation may be referred to as a hotspot base station, and the cell in overload operation may be referred to as a hotspot cell. The influence of a single hot cell on the communication network is controllable, but when a plurality of cells with strong relevance are hot cells, a large number of network drop and call drop problems occur, so that the communication quality is reduced.
In the related art, in order to solve the problem of communication quality degradation, it is necessary to determine a hot spot range where a network drop and a call drop occur, and perform maintenance processing on a base station in the hot spot range to recover the communication quality. However, the above method for determining the hot spot range has no uniform strict regulation on the division of the hot spot range, and different workers may have different division results on the hot spot range, so that the accuracy of determining the hot spot range is low.
The embodiment of the application provides a hotspot range positioning method and device, computer equipment and a storage medium. The positioning accuracy of the hot spot range can be improved. The hot spot range positioning method comprises the steps of obtaining signal coverage ranges of a plurality of hot spot cells, and obtaining an overlapping area corresponding to each hot spot cell, wherein the overlapping area is an area which is overlapped with the signal coverage ranges of other hot spot cells in the signal coverage ranges of the hot spot cells. And determining a hot spot range according to the obtained multiple overlapping areas. Therefore, in the embodiment of the application, the hot spot range is determined by acquiring the signal coverage range of the hot spot cells, determining the desired overlapping area between the hot spot cells according to the signal coverage range of the hot spot cells, and determining the hot spot cells according to the overlapping area.
In the following, a brief description will be given of an implementation environment related to the hotspot range positioning method provided in the embodiment of the present application.
Referring to fig. 1, the hotspot range locating method provided by the present application may be applied to a computer device as shown in fig. 1, where the computer device may be a server, and its internal structure diagram may be as shown in fig. 1, and the computer device includes a processor, a memory and a network interface connected through a system bus. Wherein the processor of the computer device is configured to provide computing and control capabilities. The memory of the computer device comprises a nonvolatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and a computer program. The internal memory provides an environment for the operation of an operating system and computer programs in the non-volatile storage medium. The network interface of the computer device is used for communicating with an external terminal through a network connection. The computer program is executed by a processor to implement a hotspot range locating method.
The configuration shown in fig. 1 is a block diagram of only a portion of the configuration associated with the present application, and does not constitute a limitation on the computer device to which the present application is applied, and a specific computer device may include more or less components than those shown in fig. 1, or combine some components, or have a different arrangement of components.
Referring to fig. 2, a flowchart of a hot spot range positioning method provided in an embodiment of the present application is shown, where the hot spot range positioning method may be applied in the implementation environment shown in fig. 1, and as shown in fig. 2, the hot spot range positioning method may include the following steps:
In the embodiment of the present application, before the server obtains the signal coverage of multiple hotspot cells, it needs to first determine which cells are hotspot cells.
In an optional implementation manner, the process of the server determining which cells are hotspot cells may be:
the server obtains the operation parameters of a plurality of base stations, wherein the operation parameters of the base stations comprise the maximum number of users and the wireless rate of each cell corresponding to the base station.
The server can obtain the maximum number of users and the wireless rate of each cell according to the operation parameters of the base station.
The server may set a user number threshold and a rate threshold in advance for each cell, where the user number threshold may be used to indicate the maximum number of users that can be served by the cell, and the rate threshold is the maximum wireless rate at which the cell normally operates. It should be noted that the threshold of the number of users in each cell may be the same or different, and the threshold of the rate in each cell may be the same or different.
For each cell, the server may determine whether the cell is a hotspot cell according to the user number threshold and the rate threshold corresponding to the cell, and the maximum user number and the wireless rate of the cell.
Optionally, for each cell, when any one of the maximum number of users in the cell and the wireless rate of the cell exceeds a corresponding threshold, it is determined that the cell is a hotspot cell. That is, when the maximum number of users in a cell exceeds the user number threshold and/or the wireless rate of the cell exceeds the rate threshold, the cell is determined to be a hotspot cell. For example, the threshold of the number of users is 800, the threshold of the rate is 10, and when the maximum number of users in a cell exceeds 800 and the wireless rate is higher than 10, the cell is a hotspot cell.
Correspondingly, when the maximum number of users in the cell and the wireless rate of the cell do not exceed the corresponding threshold values, the cell is determined to be a non-hotspot cell.
In an alternative implementation manner, the signal coverage of the cell is determined by the signal radiation direction and the signal radiation distance of the base station sector corresponding to the cell. In this embodiment of the application, as shown in fig. 3, the process of acquiring the signal coverage of the hotspot cell by the server may include steps 301 to 302:
Optionally, as shown in fig. 4, the process of acquiring the signal radiation distance and the signal radiation direction of each hotspot cell by the server may include:
The server may obtain a plurality of base station operating parameters, where the operating parameters of the base station include an azimuth angle of each cell corresponding to the base station, and the azimuth angle is a signal radiation angle of a sector corresponding to the cell, that is, a signal radiation direction of the cell.
In this embodiment, the server may obtain the signal radiation directions of the cells of each base station according to the operation parameters of each base station, and form a signal radiation direction set from the signal radiation directions of each cell of each base station.
The server can obtain the positions of a plurality of base stations and determine the signal radiation distance of each cell of the base stations according to the positions of the base stations.
For convenience of description, in the present embodiment, a target base station is taken as an example, and the target base station is any one of a plurality of base stations.
The server can determine the number of other base stations within a certain distance range around the target base station according to the position of the target base station and the positions of the other base stations, and determine the classification of the target base station according to the number of the other base stations within the certain distance range around the target base station.
Alternatively, a plurality of distance thresholds may be set, and the plurality of distance thresholds may be used to define the radius of a circular area formed around the target base station.
Optionally, the plurality of distance thresholds may include a first distance threshold, a second distance threshold, and a third distance threshold, where the first distance threshold may be 250m, the second distance threshold may be 500m, and the third distance threshold may be 1000 m.
And establishing a first circular area by taking the target base station as a circle center and the first distance threshold as a radius.
And determining other base stations in the first circular area according to the position of the target base station and the positions of the other base stations. For example, in the first circular area, other base stations exist in all of the four angular intervals [0 °,90 ° ], [90 °,180 ° ], [180 °,270 ° ], [270 °,360 ° ] of the target base station, and the number of the other base stations is greater than 5, and the target base station is a base station in a dense base station area.
The server may obtain a signal radiation direction of each cell of the target base station, for example, as shown in fig. 5, a circle indicates a base station, a triangle indicates a cell, and an arrow indicates a signal radiation direction of the cell, in this embodiment, the description is given by taking one cell a1 of the target base station a shown in fig. 5 as an example.
The server may obtain the signal radiation directions of the respective cells of other base stations within the first circular area, as shown by the base station B shown in fig. 5, and the signal radiation direction of each cell of the base station B may be as shown by an arrow.
As can be seen from fig. 5, the cell a1 of the target base station a is opposite to the cell B1 of the base station B, so that the server can obtain the distance d between the target base station a and the base station B and determine the signal radiation distance r of the cell a1 to be d/2.
Based on the same principle, the signal radiation distance of each cell of the target base station a can be obtained, and accordingly, the signal radiation distance of each cell of each base station can be obtained. In the embodiment of the application, the signal radiation distances of each cell of each base station are combined to obtain a signal radiation distance set.
It should be noted that, since the position of the base station and the signal radiation direction of each cell of the base station are generally not changed, the signal radiation distance set may be obtained in advance.
Optionally, when the target base station is in the first circular area, no other base station exists, or the number of the existing other base stations is small, a second circular area may be established with the target base station as a center of a circle and the second distance threshold as a radius.
And determining other base stations between the first circular area and the second circular area according to the position of the target base station and the positions of the other base stations.
The server may acquire a signal radiation direction of each cell of the target base station.
The server may also acquire signal radiation directions of respective cells of other base stations located between the first circular area and the second circular area.
The base station of the cell opposite to the signal radiation direction of each cell of the target base station is determined, a distance D between the base station of the cell opposite to the signal radiation direction of the cell of the target base station and the target base station is obtained according to the position of the target base station and the position of the base station of the cell opposite to the signal radiation direction of the cell of the target base station, and the server may determine that the signal radiation distance of the cell of the target base station is R ═ D/2.
Based on the same principle, when no other base station exists between the first circular area and the second circular area or the number of the existing other base stations is small, a third circular area can be established by taking the target base station as the center of a circle and taking the third distance threshold as the radius. And determining other base stations between the second circular area and the third circular area according to the position of the target base station and the positions of the other base stations. The process of determining the signal radiation distance of the cell of the target base station is the same as the above-disclosed process, and is not described herein again.
And 403, acquiring the signal radiation distance and the signal radiation direction of each hotspot cell from the signal radiation direction set and the signal radiation distance set.
In this embodiment of the present application, after determining whether each cell of the base station is a hotspot cell, the signal radiation direction of each hotspot cell may be obtained from the signal radiation direction set, and the signal radiation distance of each hotspot cell may be obtained from the signal radiation distance set.
Optionally, in this embodiment of the present application, a signal coverage area of the hotspot cell is a sector area.
Optionally, in this embodiment of the present application, the process of determining, by the server, the signal coverage area of each hotspot cell according to the signal radiation distance and the signal radiation direction of each hotspot cell may include the following steps:
s1: and establishing a sector area with the base station corresponding to the hot cell as the center of a circle for each hot cell.
S2: and for each hotspot cell, determining a sector area corresponding to the hotspot cell as the signal coverage of the hotspot cell.
The direction of the sector area relative to the base station is the same as the signal radiation direction of the hotspot cell, the radius of the sector area is the same as the signal radiation distance of the hotspot cell, and the included angle of the sector area is a preset included angle.
Optionally, in this embodiment of the application, the preset included angle may be a 60-degree included angle.
Optionally, that the direction of the sector area relative to the base station is the same as the signal radiation direction of the hotspot cell may mean that the direction extending outward from the bisector of the included angle of the sector area is the same as the signal radiation direction of the hotspot cell.
Optionally, the radius of the sector area is the same as the signal radiation distance of the hotspot cell, which may mean that the sector area takes the signal radiation distance of the hotspot cell as the radius.
The overlapping area is an area which overlaps with the signal coverage areas of other hotspot cells in the signal coverage area of the hotspot cell.
In an optional implementation manner, the process of the server acquiring the overlapping area corresponding to the hotspot cell may be: the server may obtain a nationwide base station profile or a base station profile for a portion of a particular area, the base station profile including the relative locations of the base stations. In the embodiment of the present application, the signal coverage of each hotspot cell may be drawn on the base station distribution diagram. Moreover, as shown in fig. 6, the server may determine the overlapping area of the signal coverage of each hotspot cell according to the area position of the signal coverage of each hotspot cell in the base station distribution diagram. Wherein, the overlapped state includes both the overlapped and the non-overlapped condition. The relevance of the hot spot cells with overlapped signal coverage is stronger, and the relevance of the hot spot cells without overlapped signal coverage is weaker.
In an optional implementation manner, the obtaining, by the server, an overlapping area corresponding to the hotspot cell refers to an overlapping area where all of the hotspot cells are overlapped with each other.
For example, a hotspot cell a, a hotspot cell B, a hotspot cell C, a hotspot cell D, and a hotspot cell E exist, where a signal coverage of the hotspot cell a, a signal coverage of the hotspot cell B, a signal coverage of the hotspot cell C, and a signal coverage of the hotspot cell E overlap each other, and meanwhile, a signal coverage of the hotspot cell D overlaps a signal coverage of the hotspot cell B, but does not overlap the signal coverage of the hotspot cell a, so that an overlapping region where the hotspot cell a, the hotspot cell B, the hotspot cell C, and the hotspot cell E overlap together is obtained.
In another optional implementation manner, the obtaining, by the server, an overlapping area corresponding to the hotspot cell refers to an overlapping area in which a plurality of hotspot cells are sequentially overlapped.
For example, there are a hotspot cell a, a hotspot cell B, a hotspot cell C, a hotspot cell D, a hotspot cell E, and a hotspot cell F, where a signal coverage of the hotspot cell a overlaps with a signal coverage of the hotspot cell B, a signal coverage of the hotspot cell B overlaps with a signal coverage of the hotspot cell C, and a signal coverage of the hotspot cell a overlaps with a signal coverage of the hotspot cell D, then an overlapping region corresponding to the hotspot cell a and the hotspot cell B is obtained, an overlapping region corresponding to the hotspot cell B and the hotspot cell C is obtained, and an overlapping region corresponding to the hotspot cell a and the hotspot cell D is obtained.
As shown in fig. 7, when the signal coverage of the hotspot cell a overlaps with the signal coverage of the hotspot cell B, an overlapping area M is obtained. And when the signal coverage range of the hotspot cell B is overlapped with the signal coverage range of the hotspot cell C, acquiring an overlapping area N.
In an alternative implementation manner, as shown in fig. 8, the process of determining, by the server, the hot spot range according to the obtained multiple overlapping areas may include the following steps:
The circular area is established by taking a target point in the overlapping area as a circle center and taking a preset length as a radius. The resulting circular area of each overlap area may be as shown in fig. 9.
Alternatively, the target point of the overlap area may be any point within the overlap area, or may be a center point of gravity of the overlap area, or may be a center point of the overlap area.
Alternatively, the radius length of the circular region can be calculated by formula (1), where formula (1) is as follows:
r ═ δ max (d) formula (1).
Where δ is a length coefficient, and optionally, δ is 1/4. max (d) is the longest radius among the radii of the reference ranges corresponding to the hot spot cells corresponding to the overlapping area when overlapping.
For example, reference ranges of a hotspot cell a, a hotspot cell B, and a hotspot cell C are overlapped to obtain an overlapped area O, where a radius of the reference range corresponding to the overlapped area O obtained by overlapping the hotspot cell a with the hotspot cells B and C is L1, a radius of the reference range corresponding to the overlapped area O obtained by overlapping the hotspot cell B with the hotspot cells a and C is L2, and a radius of the reference range corresponding to the overlapped area O obtained by overlapping the hotspot cell C with the hotspot cells a and B is L3, where L2> L3> L1, then corresponding max (d) in equation (1) is L2.
Optionally, in this embodiment of the present application, when the signal coverage of one or some hotspot cells does not overlap with the signal coverage of any other hotspot cell, for convenience of description, the hotspot cell is referred to as an independent hotspot cell. Since the independent hotspot cell does not have an overlapping area with other cells, the embodiment of the present application provides that the process of determining the circular area of the independent hotspot cell by the server may be:
and acquiring the signal radiation range of the independent hotspot cell.
And forming a circular area by taking the central point on the bisector of the included angle of the fan-shaped area corresponding to the signal radiation range of the independent hotspot cell as the center of a circle and the preset length as the radius. The preset length may be calculated according to formula (1) to obtain r ═ δ max (d), and max (d) is the signal radiation distance of the individual hotspot cell.
Optionally, in this embodiment of the present application, the signal coverage of the non-hotspot cell is determined by the signal radiation direction and the signal radiation distance of the non-hotspot cell. Optionally, in this embodiment of the application, the server may obtain the signal radiation direction of each non-hotspot cell from the signal radiation direction set, and the server may obtain the signal radiation distance of each non-hotspot cell from the signal radiation distance set.
Alternatively, the server may determine the signal coverage of each non-hotspot cell based on the schemes disclosed in step 201 and steps 301-302.
It should be noted that, in the embodiment of the present application, each circular area may obtain one hot spot range, that is, each overlapping area separately forms one hot spot range.
In this embodiment of the present application, the process of the server correcting the circular area according to the signal coverage of each non-hotspot cell may be:
for each circular area, the server may draw the signal coverage of each non-hotspot cell in the base station distribution diagram, and determine the overlapping state of each non-hotspot cell and the circular area according to the area position of the signal coverage of each non-hotspot cell in the base station distribution diagram.
When the signal coverage range of one or more non-hotspot cells is overlapped with the circular area, acquiring the overlapped area, removing the overlapped area from the circular area, and determining the circular area from which the overlapped area is removed as the hotspot range corresponding to the circular area.
It is noted that non-hotspot cells that do not overlap with a circular area can be ignored.
The embodiment of the application provides a hotspot range positioning method which can improve the positioning accuracy of a hotspot range. The hot spot range positioning method comprises the steps of obtaining signal coverage ranges of a plurality of hot spot cells, and obtaining an overlapping area corresponding to each hot spot cell, wherein the overlapping area is an area which is overlapped with the signal coverage ranges of other hot spot cells in the signal coverage ranges of the hot spot cells. And determining a hot spot range according to the obtained multiple overlapping areas. Therefore, in the embodiment of the application, the hot spot range is determined by acquiring the signal coverage range of the hot spot cells, determining the desired overlapping area between the hot spot cells according to the signal coverage range of the hot spot cells, and determining the hot spot cells according to the overlapping area.
In an optional implementation manner, in this embodiment of the application, as shown in fig. 10, a process of the server acquiring the overlapping area corresponding to the hotspot cell may further be:
The increment of the radius of the hot spot cell is the length of increase of the radius of the reference range from the radius of the last acquired reference range when the reference range is acquired each time.
Optionally, the process of the server obtaining the radius increment of the hotspot cell may be:
and equally dividing the signal radiation distance of the hotspot cell to obtain the radius increment of the hotspot cell.
Optionally, the process of acquiring the radius increment of the hotspot cell by the server may further include the following steps:
h1, acquiring the hotspot grade of the hotspot cell.
The hot spot grade of the hot spot cell is used for representing the network drop and call drop degree of the hot spot cell.
As can be seen from the disclosure of step 201, the operation parameters of the base station include the maximum number of users and the radio rate of each cell corresponding to the base station. The server can evaluate the severity of the network drop and call drop problem in the hotspot cell according to the maximum number of users in the hotspot cell and the wireless speed.
Optionally, the server may obtain a hot spot evaluation value of the hot spot cell through a weighting operation according to the maximum number of users and the wireless rate of the hot spot cell, where the hot spot evaluation value may be used to characterize a severity of a network drop and a call drop problem in the hot spot cell. Optionally, the hot spot evaluation value of the hot spot cell is positively correlated with the severity of the network drop and call drop problem existing in the hot spot cell.
In the embodiment of the application, the server may preset a plurality of hotspot levels, different hotspot levels correspond to different hotspot evaluation value ranges, and the server may determine the hotspot level of each hotspot cell according to the hotspot evaluation value range in which the hotspot evaluation value of each hotspot cell is located.
Optionally, in this embodiment of the present application, the higher the hotspot level of the hotspot cell is, the more serious the network drop and call drop problem existing in the hotspot cell is.
Optionally, in the embodiment of the present application, the hotspot cells may be classified into five levels according to the hotspot evaluation values.

Optionally, the radius increment of the hotspot cell is the reciprocal of the hotspot level of the hotspot cell.
Optionally, the hotspot level is inversely related to the increment of the radius of the hotspot cell.
In an optional implementation manner, optionally, the process of the server obtaining the radius increment of the hotspot cell according to the hotspot class of the hotspot cell may be:
presetting a calculation formula of radius increment, as shown in formula (2):
wherein b represents the radius increment, L represents the hotspot grade of the hotspot cell, wherein, L is more than 0 and less than or equal to N, N represents the grade number of the hotspot grade, and d represents the signal radiation distance of the hotspot cell.
According to the formula (2), the signal radiation distance of the hotspot cell and the hotspot grade of the hotspot cell are input into the formula (2) to calculate the radius increment of the hotspot cell.
When the reference range is obtained from the signal coverage range of the hotspot cell for the first time, the server may form a sector area in the signal coverage range of the hotspot cell by using the base station corresponding to the hotspot cell as a center of a circle and using the radius increment as a radius, where an included angle of the sector area is equal to an included angle corresponding to the signal coverage range of the hotspot cell.
When the reference range is acquired from the signal coverage range of the hotspot cell for the second time, the server may expand the radius of the reference range acquired for the first time to 2 times of the radius increment.
By analogy, when the reference range is acquired from the signal coverage range of the hotspot cell at the nth time, the server can expand the radius of the reference range acquired at the nth time to n times of radius increment.
It should be noted that, when the reference ranges of the hotspot cell a and the hotspot cell B overlap, it may happen that, as the reference range of the hotspot cell is enlarged, the overlapping area of the hotspot cell a and the hotspot cell B is also enlarged, in this case, in this embodiment of the present application, only the overlapping area of the reference range of the hotspot cell a and the reference range of the hotspot cell B when the reference ranges of the hotspot cell a and the hotspot cell B overlap for the first time is obtained.
For example, as shown in fig. 7, when the first acquired reference range of hotspot cell a overlaps with the first acquired reference range of hotspot cell B, the overlapping area M is acquired.
When the reference range acquired by the hotspot cell a for the second time overlaps with the reference range of the hotspot cell B again, as shown by a dotted line in fig. 7, the overlapping area M when the hotspot cell a overlaps with the hotspot cell B for the first time is still used as the overlapping area of the hotspot cell a and the hotspot cell B.
Continuing as shown in fig. 7, when the reference range acquired by the hotspot cell B for the third time overlaps with the reference range of the hotspot cell C, the overlapping area N of the hotspot cell B and the hotspot cell C is acquired.
In the embodiment of the application, the reference range of the hotspot cell can be gradually increased based on the radius increment until the reference range of the hotspot cell is the same as the signal coverage range of the hotspot cell.
It should be noted that, in the embodiment of the present application, because there is a difference in the radius of the reference range of the corresponding hotspot cell when different hotspot cells are first overlapped, in the embodiment of the present application, the overlap area is obtained by gradually increasing the radius of the reference range.
In an optional implementation manner, after determining the hot spot ranges according to the obtained multiple overlapping areas, the server may determine, according to the base station distribution map, multiple base stations included in each hot spot range. In the embodiment of the application, for each hotspot range, a base station which needs hotspot maintenance needs to be selected from a plurality of base stations in the hotspot range. As shown in fig. 11, the process of the server selecting the base station requiring the hot spot maintenance may be:
The process of the server acquiring the hotspot parameters of the multiple base stations in the hotspot range may be:
and for each base station in the hotspot range, acquiring the last hotspot maintenance result of the base station.
And acquiring the hot spot rating and the grade weight of the base station according to the last hot spot maintenance result of the base station.
And taking the hot spot rating and the grade weight of the base station as hot spot parameters of the base station.
The hotspot rating is used for representing the probability that the base station is a base station needing hotspot maintenance, and the grade weight is a weight corresponding to the hotspot rating.
And the grade weight is preset for each hotspot grade.
Taking the base station a as an example, the base station a is determined as a base station that needs hotspot maintenance for the last time, and after the hotspot maintenance is performed on the base station a, the problem of network drop and call drop within a hotspot range is effectively improved, so that the last hotspot maintenance result of the base station a is a good effect, and a hotspot rating corresponding to the good effect is obtained.
If the base station A is determined as the base station needing the hot spot maintenance last time, and after the hot spot maintenance is carried out on the base station A, the problem of network drop and call drop in the hot spot range is not effectively improved, the last hot spot maintenance result of the base station A is poor in effect, and the corresponding hot spot rating with the poor effect is obtained.
And taking the hotspot rating and the grade weight corresponding to the last hotspot maintenance result of the base station A as the current hotspot parameter of the base station A.
The hotspot score is used for representing the probability of the hotspot problem of the base station.
Optionally, in this embodiment of the application, the hotspot parameters of each base station may further include historical overload time points, historical duration, hotspot times, activity types, base station combinations, and radius increments, and the hotspot score is obtained by performing weighted summation according to the hotspot parameters of each base station.
