The reasons may be environmental anomalies (e.g., high temperature, excessive humidity), power outages, hardware failures, intrusion or other non-disaster resistant, etc. When the service of the base station is interrupted, the reported alarms comprise, but are not limited to, a radio frequency unit maintenance link abnormal alarm, a baseband processing unit infrared interface (Building Baseband Unit Infrared Interface, abbreviated as BBU IR) interface abnormal alarm, a radio frequency unit IR interface abnormal alarm, a base station control plane transmission interruption alarm, a network element connection interruption alarm and a cell out-of-service alarm.
Interrupt compensation: it is generally referred to that after the cell service is interrupted, the service compensation is performed on the user terminal by the other base station.
Cell handover (HO for short): in the communication process, the user terminal is switched from the cell with poor signal to the cell with better signal so as to maintain the communication smooth.
Covering the cavity: areas without signal coverage. When the signals of the base station cannot cover certain areas, the areas cannot normally receive or transmit the signals, and coverage holes are formed.
Neural network model: a computational model for simulating human brain neuron interaction mode. It is formed by a large number of simple processing units (called neurons) widely interconnected, and is particularly suitable for handling imprecise and ambiguous information processing problems requiring consideration of many factors and conditions simultaneously.
An air base station: an unmanned aerial vehicle flying at a height of about 20 km from the ground is driven by solar energy and has a base station function. Such a base station may provide additional wireless communication services or address signal coverage issues for a particular area in addition to or as an alternative to a conventional base station.

Fig. 2 is a flowchart of a method for handling a base station failure according to an embodiment of the present application, as shown in fig. 2, the method includes the following steps:
step S202, acquiring state information of a fault base station, wherein the state information comprises at least one of the following: the state information of the fault base station reported by the fault base station and the state information of the fault base station reported by other base stations in the coverage area of the fault base station.
In the step S202, the status information of the faulty base station may include information such as the fault type, the fault location, and the fault time, and the nature and the scope of influence of the base station fault may be better known through the status information of the faulty base station reported by the faulty base station or the status information of the faulty base station reported by other base stations within the coverage area of the faulty base station.
In this embodiment of the present application, the network management device (network management background) is used as an execution main body, and the base station may report an alarm (for example, the base station reports an abnormal alarm of the BBU IR interface) when a fault occurs, and the network management background locates the faulty base station according to the alarm information. If the base station suddenly fails to report the alarm information, the network management background discovers a fault through the heartbeat information of the base station, tries to wake up the fault base station, and judges the fault base station as a fault base station to be processed if the wake-up fails. Meanwhile, the network management background can also comprise a monitoring system for monitoring the switching (HO) behaviors of the user terminals near the fault base station in real time, wherein the switching behaviors of a large number of user terminals possibly indicate that the nearby base station has faults or abnormal services, and the network management background can determine the fault range more quickly and process the targeted faults through timely monitoring and analysis.
Step S204, after the service of the fault base station is interrupted, determining whether a coverage hole exists in the coverage area of the fault base station.
In the step S204, the coverage hole refers to an area where the coverage of the signal is insufficient or missing, that is, an area where the signal cannot be normally received or transmitted, and by determining whether the coverage hole exists or not, the extent of the influence of the base station failure on the communication service can be further evaluated.
Step S206, when coverage holes exist in the coverage area, the downlink power of other base stations in the coverage area is increased to complement the coverage holes.
In step S206, by increasing the downlink power of the other base stations in the coverage area and increasing the strength of the signals sent by the other base stations in the coverage area to the coverage hole area, coverage holes existing in the coverage area of the failed base station can be effectively compensated, and the signal quality can be improved, so that the communication service in the coverage area of the failed base station can be recovered.
Through the steps S202 to S206, the purpose of restoring communication service in the coverage area of the fault base station by judging whether the coverage area of the fault base station has coverage holes or not and adopting corresponding coverage hole complement measures is achieved, so that the technical effects of comprehensively considering the coverage holes, base station resources and other factors to form short-time efficient interruption compensation for the fault base station and avoiding resource waste are achieved, and the technical problems that the operation time is overlong, the coverage holes are not found by default and part of resources are wasted in the base station service interruption compensation method in the related art are solved. The following is a detailed description.
In the above steps, the coverage hole of the base station may be complemented in the following form, but is not limited thereto:
and (3) base station power adjustment: and increasing the transmitting power of other base stations so that signals of the base stations can cover the cavity area. But this approach may result in increased interference from neighboring base stations.
And (3) antenna adjustment: coverage is optimized by changing the direction, downtilt or beamwidth of the antennas of the other base stations. For example, adjusting the downtilt of the antenna may result in better coverage of the signal to the ground.
The other base stations may be newly added base stations: new base stations or small base stations (e.g., micro base stations, etc.) are deployed within the coverage hole area to provide additional signal coverage.
Adopts a relay technology: and the other base stations are used as relay stations to receive signals from the base stations, and the signals are amplified and forwarded to the coverage hole area, so that the coverage range of the base stations is expanded.
In the above step, determining whether a coverage hole exists in the coverage area of the faulty base station includes: obtaining the geographic coordinates of the fault base station, and determining the coverage area of the fault base station according to the geographic coordinates; counting the geographic position information of the user terminal reported by other base stations in the coverage range in a preset time period, and determining the distribution information of the user terminal according to the geographic position information of the user terminal; determining whether coverage holes exist in the coverage area of the fault base station according to the distribution information; or obtaining the geographic position information of the user terminal accessed to the fault base station; and analyzing the geographical position information by adopting a neural network model to obtain an analysis result, wherein the analysis result is used for indicating whether coverage holes exist in the coverage area.
Wherein the neural network model comprises:
input layer: the input of the model is the geographical location of the user terminal, which may be expressed as latitude and longitude coordinates or other forms of geographical identification.
Hidden layer: depending on the complexity of the problem, one or more hidden layers may be designed. These hidden layers are responsible for extracting useful features from the input data.
Output layer: the output layer is a binary classifier, and the output value is whether coverage holes exist in the region or not. Typically, the output may be converted to a probability value using a sigmoid or softmax function.
Since the above model solves the binary classification problem, the cross entropy loss function can be selected as the optimization objective.
The training data of the model may be matrix data and corresponding output results (positions of coverage holes), for example:
train_x＝[2 2 1 1 1 1
2 1 0 0 1 1
1 1 0 0 1 1
1 1 1 1 1 2]，
train y = position of coverage hole,
wherein, train_x represents an input matrix, train_y represents an output, 0 represents a coverage hole, 1 represents a signal, and 2 represents that the signal is very strong. The values in the matrix merely represent the signal strength or strength level, and are not necessarily 1 and 2, and may be calculated according to a power attenuation formula, or obtained by sampling in the field, where each value corresponds to a respective sampling point in the area. The spacing between the individual sampling points may be 10 meters or 5 meters. If it is 10 meters, the upper surface is a 60m x 40m region.
The initial position of the matrix marks longitude and latitude and is recorded in the background; and converting the predicted result into longitude and latitude after obtaining the predicted result, thereby determining the signal intensity of each sampling point, and further determining the coverage hole according to the signal intensity.
In other embodiments, the training data may also be: geographic coordinates and power of the base station, and location of coverage holes, for example:
train_x＝[3 0 0 0 0 0
0 0 0 0 0 0
0 0 0 0 0 0
0 0 0 0 0 2]，
train y = position of coverage hole,
wherein a non-zero value (3 or 2) represents the location or power of the base station; the power value is not necessarily 3 or 2, and should be determined according to practical situations, and 0 represents the position of the cavity.
Specifically, the train_x is a matrix, where the subscript of each value represents latitude and longitude coordinates or relative coordinates of the base station, and is calculated in the following manner: start longitude and latitude value or start coordinate value + subscript sampling interval. And the background records the initial longitude and latitude or initial coordinate value of the matrix. A value of 0 indicates that there is no base station at the location, a value greater than 0 indicates that there is a base station at the location, and the transmit power of the base station is equal to the value. For example, 3 represents a base station having a transmit power of 3 at the location.
Wherein, the meaning of the "subscript of each value" mentioned above is: when encoding matrix data, an element in the matrix is typically given a subscript to identify the location of each element. The subscripts are typically indicated by two numbers, corresponding to the row and column numbers, respectively. For example, in a two-dimensional matrix, the element a [ i ] [ j ] represents an element of the ith row and the jth column, and by using the subscript, the position of each element in the matrix can be accurately specified, and matrix operation and manipulation can be performed easily.
the train_y is a vector representing the position of the coverage hole.
In this way, training data sets train_x and train_y may be used to train a model to fit a power attenuation formula. During the training process, the model will try to learn and predict the law of power decay and adjust the parameters according to the actual data to optimize the predicted performance.
In the embodiment of the application, determining whether a coverage hole exists in the coverage area of the faulty base station mainly relates to two methods, one is to determine whether the coverage hole exists in the coverage area based on the geographic coordinates of the base station and the distribution information of the user terminals, and the other is to analyze the geographic position information of the user terminals based on a neural network model to judge whether the coverage hole exists in the coverage area, and the method specifically comprises the following steps:
in the method for determining whether coverage holes exist in a coverage area based on the geographic coordinates of a base station and the distribution information of user terminals, the original coverage area (longitude and latitude) of the base station can be calculated according to the geographic coordinates of a fault base station, the geographic position information of the user terminals reported by other base stations with signals in the coverage area in a preset time period (such as the past 1 min) is obtained, and the distribution range of the user terminals is drawn according to the reported geographic position information of the user terminals, so that whether the coverage holes exist in the distribution range is determined. The other base stations with signals in the coverage area of the faulty base station may be other base stations B, C, D in the coverage area of the faulty base station a, where the user terminal may receive signals, etc.; since the coverage area of the currently used 5G small base station is 200m, the coverage area of the 4G macro station is 1.5km, and the real signal coverage area is generally larger than the two values (but the signal is not available because the level value is too low), the base station B, C, D includes other base stations near the base station a, and also includes the 4G macro station which is far away and can receive the signal.
Based on the design concept, a specific implementation process for determining the coverage hole provided in the embodiment of the present application is as follows:
step 1, determining geographic coordinates of a fault base station: first, geographical coordinate information of a faulty base station needs to be acquired, which can be generally acquired from configuration data of the base station or a network management system.
Step 2, calculating the original coverage: the original coverage area of the fault base station can be calculated by utilizing parameters such as geographic coordinates, transmitting power and the like of the fault base station and combining a propagation model or a Geographic Information System (GIS) tool, and the original coverage area is usually expressed by longitude and latitude coordinates.
Step 3, obtaining information of other base stations and user terminals with signals: information of other base stations with signals in the coverage area of the fault base station is obtained from the network, wherein the information comprises the geographic position, the transmitting power and the like. Meanwhile, the user terminal information reported by the base stations in the past 1min is obtained, wherein the user terminal information comprises the geographic position, the received signal strength and the like of the user terminal.
Step 4, drawing the distribution range of the user terminal: and drawing the distribution range of the user terminals on the map by using the acquired user terminal information. This can be achieved by marking the geographical location of the user terminal on a map and performing a visualization process based on information such as received signal strength.
Step 5, judging whether a coverage hole exists or not: by analyzing the distribution range of the user terminal, whether coverage holes exist or not can be judged. Since the coverage hole is generally represented as a region where the signal strength received by the user terminal is weak, a certain signal strength threshold may be set to determine whether the coverage hole exists, for example, the signal strength is lower than a certain threshold.
In the method for judging whether coverage holes exist in a coverage area based on the geographic position information of the user terminal analyzed by the neural network model, the input of the neural network model is the geographic position of the user terminal, and the analysis result for indicating whether the coverage holes exist in the coverage area is obtained by analyzing the geographic position of the user terminal and is used as the output of the neural network model. It should be noted that, the method assumes that no place where the unsuitable crowd resides exists within the coverage area of the base station.
In the above step, increasing the downlink power of other base stations in the coverage area includes: and increasing the downlink power of other base stations according to a preset gain, wherein the preset gain is determined according to a functional relation among the coverage radius of the fault base station, the transmitting antenna gain, the receiving antenna gain and the system loss.
In the embodiment of the application, for the case that coverage holes exist in the coverage area, the coverage holes can be effectively compensated by increasing the downlink power of other base stations in the coverage area, so as to improve the communication service quality. The downlink power of other base stations in the coverage area is determined according to the functional relation among the coverage radius of the fault base station, the gain of the transmitting antenna, the gain of the receiving antenna and the system loss, and the specific preset gain relation is as follows:
where R represents the coverage radius of the faulty base station, pt represents the power, gt represents the transmit antenna gain, gr represents the receive antenna gain, λ represents the signal wavelength, and L represents the system path loss.
In the above step, before increasing the downlink power of other base stations according to the preset gain, the method further includes: acquiring a neighbor cell table of a fault base station; and determining a base station for compensating the coverage hole from the neighbor cell table, and increasing the downlink transmitting power of the base station determined from the neighbor cell table so as to complement the coverage hole.
In the above step, before increasing the downlink power of other base stations in the coverage area, the method further includes: after increasing the downlink transmission power of the base station determined from the neighbor cell table, it is determined that the coverage hole is not complemented or that there is an overload of the base station determined from the neighbor cell table.
In the above step, after increasing the downlink transmission power of the base station determined from the neighbor cell table, the method further includes: and if the coverage hole is not completed, notifying the macro station or the air base station to complete the coverage hole.
The purpose of using the macro station to perform gain is to quickly and effectively recover the signal service of the coverage area of the fault base station by using the larger transmitting power and coverage area of the macro station. Thus, the user can still obtain stable signal coverage and communication service in the coverage hole area, and the reliability and service quality of the network are improved.
Meanwhile, the air base station performs cell outage compensation as another option. The aerial base station has the characteristics of quick deployment and flexibility, and can provide temporary signal coverage in a short time so as to further accelerate the service recovery process. By the cooperative work of the macro station gain and the air base station, the service of the coverage area of the original fault base station can be effectively recovered in the shortest time.
In the embodiment of the present application, other base stations with signals in the coverage area are increased by downlink power according to the following rule:
(1) Acquiring a neighbor cell table of a fault base station, determining a base station for compensating the coverage hole from the neighbor cell table, and performing downlink power gain on the base station for compensating the coverage hole determined from the neighbor cell table according to the preset gain so as to fill coverage holes possibly existing in the coverage range of the fault base station. The neighbor cell table of the fault base station is used, and the information of the neighbor cell base station is utilized, because the calculation mode of the neighbor cell table is that the mobile phone can receive other available base stations, only the table is needed to be read, other calculation is not needed, and the time for cell interruption compensation is saved.
(2) After performing downlink power gain operation on other base stations in the coverage area, if a coverage hole is not complemented or the base station determined in the neighbor cell table is overloaded; judging whether the coverage radius after the gain is larger than the coverage radius of the fault base station or not according to the preset gain for each base station, and judging that the coverage hole is complemented if the coverage radius after the gain is larger than or equal to the coverage radius of the fault base station; and if the coverage radius after the re-gain is smaller than the coverage radius of the fault base station, judging that the coverage hole is not complemented.
(3) In the case that the coverage hole is not yet completed, the macro station further away is used for gain or the air base station is used for cell outage compensation, so that the service of the coverage area of the fault base station is restored in the shortest time. And after the coverage hole is completed, performing uplink power gain until the service of the area is completely restored.
It should be noted that if the base station has a power saving mode (such as early morning failure), the power saving mode of the base station should be awakened.
In the above steps, further comprising: under the condition that coverage holes do not exist in the coverage area, switching the user terminal accessed to the fault base station to a neighboring base station of the fault base station; after switching to the neighbor base station of the fault base station, under the condition that the neighbor base station of the fault base station is overloaded, increasing the power of the neighbor base station, and increasing the macro station power of the fault base station, wherein the distance between the macro station power and the neighbor base station is smaller than a distance threshold; after switching to the neighbor base station of the fault base station, under the condition that the signal strength of the neighbor base station is lower than a preset threshold value, the power of other base stations is increased or the power of the neighbor base station is increased.
In the embodiment of the present application, for the case that coverage areas do not have coverage holes, since the faulty base station cannot provide normal communication service, the user terminal accessing the faulty base station can be switched to the neighboring base station of the faulty base station, and the base station connected by the user terminal is switched, so as to avoid the problem that the coverage holes cannot be connected or the signal quality is poor.
Specifically, after a user terminal in the coverage area of a fault base station is switched to a neighboring base station of the fault base station, judging whether the switched neighboring base station is overloaded, and if the neighboring base station is not overloaded, not processing; if the neighbor base station is overloaded, the power of the neighbor base station can be increased, and the macro station power which can receive the user signals in the distance near the fault base station is increased at the same time, namely, the distance of the fault base station is smaller than the macro station power of the distance threshold value, so that the signal load of the neighbor base station is balanced, and the user can be ensured to be connected with the stable signal in the coverage area of the fault base station; meanwhile, judging the signal intensity of the neighbor base station, if the signal intensity of the neighbor base station is lower than a preset threshold value, and if the service cannot be normally performed (such as the user drop rate is increased sharply), the uplink power and the downlink power of the neighbor base station and other base stations with signals in the coverage area of the neighbor base station can be properly increased, the coverage area of the base station is further optimized, and good connection can be still performed in the area with weak signals by the user service (for example, the user drop rate is ensured to be normal, and the packet loss rate is ensured to be normal).
It should be noted that if the base station has a power saving mode (such as early morning failure), the power saving mode of the base station should be awakened.
In the above steps, further comprising: under the condition that the fault base station fails to send the fault alarm, the network management equipment of the fault base station generates the fault alarm and sends the fault alarm to the maintenance terminal.
In the embodiment of the application, if the alarm report fails on the fault base station, if the fault base station suddenly fails to report alarm information, a network management background of the fault base station can generate a fault alarm and send the fault alarm to a maintenance terminal so as to remind relevant maintenance personnel to process the fault alarm; different processing strategies can be adopted according to the occurrence time of the faults, and if the faults of the base station occur in the early morning, maintenance personnel can be reminded of processing the faults in the working time of the day; if a base station failure occurs during the day, maintenance personnel will be immediately notified to go to the failed base station for maintenance.
