Technical Field

[0001] The present invention relates to the field of wireless communication base station technology, and in particular to a method, apparatus, electronic device and storage medium for predicting the outage of a wireless communication base station. Background Technology

[0002] With the development of technology, the coverage of wireless communication base stations is becoming increasingly wider. Maintaining the stable operation of these base stations is becoming increasingly important, such as preventing them from going out of service. To effectively address the issue of base station outages, staff need to accurately predict the specific timing of such outages.

[0003] Currently, traditional base station outage prediction schemes typically rely on expert experience to provide the normal voltage fluctuation range of the base station, and then calculate the backup power duration of the base station based on the voltage fluctuation, thereby predicting the base station outage.

[0004] However, the normal voltage fluctuation range of base stations in traditional base station outage prediction schemes relies on expert experience, which can lead to inaccurate predictions due to inaccurate settings. Furthermore, settings based on human experience are highly subjective and cannot avoid inaccuracies. Summary of the Invention

[0036] Example 1

[0037] Figure 1 This is a flowchart illustrating a method for predicting the outage of a wireless communication base station, as provided in Embodiment 1 of the present invention. This embodiment is applicable to situations involving the prediction of wireless communication base station outages, particularly to situations where the outage time of a wireless communication base station is predicted after a power outage under the current load. This method can be executed by a wireless communication base station outage prediction device, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0038] S110. Obtain the power supply voltage of the wireless communication base station.

[0039] In this embodiment, a wireless communication base station in a mobile communication network refers to a general term for fixed network equipment responsible for establishing connections with user terminals via a wireless air interface and for allocating resources, forwarding data, and managing mobility. A wireless communication base station is the infrastructure of a wireless access network and provides the physical guarantee for communication. A wireless communication base station can consist of a tower / pole, antennas, and a server room / cabinet. The server room in a wireless communication base station houses core processing equipment, namely a baseband unit (BBU), power supply, transmission equipment, etc., responsible for processing signals and connecting to the core network. The power supply voltage can refer to the voltage that supplies power to the server room. In this embodiment, to facilitate monitoring of the BBU's operating status, the power supply voltage can be the BBU's power supply voltage.

[0040] Wireless communication base stations are typically powered by mains electricity. To delay the outage of base stations after a power outage and to provide temporary power, most base stations are equipped with temporary power batteries. Some base stations also have generators in addition to batteries. During a mains power outage, the batteries in the base station supply power. During battery power supply, the supply voltage continuously decreases. When the voltage drops to the level of the first power-off, the base station partially goes offline. At this time, the base station cannot provide network and telephone communication services to users, but it can still maintain data transmission with other base stations. This can be understood as the BBU (Baseband Unit) not working, but the transmission equipment working normally. When the supply voltage continues to drop to the level of the second power-off, the base station completely goes offline. At this time, the base station cannot provide network and telephone communication services to users, and cannot maintain data transmission with other base stations. This can be understood as both the BBU and the transmission equipment not working.

[0041] Specifically, the power supply voltage of the wireless communication base station is acquired in real time. For example, the power supply voltage of the wireless communication base station is continuously acquired from the BBU power supply records at a 15-minute granularity (i.e., acquired every 15 minutes). Based on the voltage characteristics of different voltage types, the power supply voltage is identified, thereby determining whether the wireless communication base station is powered by mains power.

[0042] For example, the mains power supply voltage and the battery power supply voltage have different characteristics. One of these differences is the difference in the voltage value. This can be understood as different types of voltage having different normal supply voltage ranges. The mains power supply voltage is higher than the battery power supply voltage. If the supply voltage is within the mains power supply range, then the wireless communication base station is determined to be powered by the mains power. If the supply voltage is within the battery power supply range, then the mains power is cut off, and the wireless communication base station is powered by the battery.

[0043] As an optional implementation of this disclosure, the method further includes: when it is detected that the voltage difference between the power supply voltage of the wireless communication base station and the mains power supply voltage meets the preset base station power outage conditions, the power supply voltage is determined to be the base station power outage voltage.

[0044] In this embodiment, the mains power supply voltage can refer to the voltage at which the mains power normally supplies the wireless communication base station. The preset base station power outage condition can refer to a pre-set condition that uses voltage differences to determine whether the wireless communication base station is powered by mains power. For example, the preset base station power outage condition can be, but is not limited to, a voltage drop that occurs when the base station BBU voltage value meets the normal range of the mains power supply voltage for the base station, thereby determining that the base station has stopped receiving mains power. The base station power outage voltage can refer to the voltage when the mains power stops supplying power to the wireless communication base station, or the power supply voltage of the wireless communication base station when the mains power is interrupted.

[0045] Specifically, the voltage difference between the power supply voltage of the wireless communication base station and the mains power supply voltage is determined. If the voltage difference is greater than a preset voltage difference threshold, the mains power supply is cut off, and the battery supplies power to the wireless communication base station, with the supplied voltage being determined as the base station's power outage voltage. If the voltage difference is less than or equal to the preset voltage difference threshold, the mains power supply is determined to be normal.

[0046] For example, the mains power supply voltage can be determined in advance as follows: Calculate the mains power supply voltage of the base station. The initial calculation uses the base station BBU voltage data from the past week or 7 days, excluding abnormal voltages. Abnormal voltages are defined as voltage fluctuations exceeding 3V. Data generated after the occurrence of abnormal voltages also needs to be excluded. Then, the average of the most recent 7 consecutive days of voltage data from the past month is used for calculation. If the condition is still not met, the calculation is repeated only after new voltage data meets the condition.

[0047] S120. When the power supply voltage is detected to be the base station power outage voltage, the reference battery voltage change curve of the wireless communication base station is obtained, and the battery power supply start voltage of the wireless communication base station is determined based on the power supply voltage and the base station power outage voltage.

[0048] In this embodiment of the disclosure, the reference battery voltage change curve may refer to a battery voltage change curve applicable to the current wireless communication base station. The battery voltage change curve may refer to a curve showing the change of battery supply voltage over time. The battery supply start voltage may refer to the voltage at which the battery begins to supply power to the wireless communication base station, replacing mains power.

[0049] Specifically, when the power supply voltage is detected to be the base station outage voltage, a preset battery voltage change function and battery power supply information from the previous mains power outage and battery power supply period marked as valid by the wireless communication base station are obtained. The battery power supply information is then substituted into the preset battery voltage change function to determine the reference battery voltage change curve for the wireless communication base station. The battery power supply information may include, but is not limited to: the battery power supply start voltage, the battery power supply start time corresponding to the battery power supply start voltage, the battery power supply time within a preset time period after the battery power supply start time, and the battery power supply voltage.

[0050] Specifically, among the continuous power supply voltages, the power supply voltage that shows a decreasing trend before the base station power outage voltage and corresponds to the earliest power supply time is determined as the battery power supply start voltage of the wireless communication base station during this mains power outage and battery power supply.

[0051] As an optional implementation of this disclosure, obtaining the reference battery voltage change curve of the wireless communication base station may specifically include: if the historical outage status of the wireless communication base station meets the preset outage status, then the historical battery voltage change curve of the wireless communication base station is obtained as the reference battery voltage change curve; if the historical outage status of the wireless communication base station does not meet the preset outage status, then the historical battery voltage change curve of other wireless communication base stations is obtained as the reference battery voltage change curve of the wireless communication base station.

[0052] In this embodiment of the disclosure, historical outage status can refer to the outage status of a wireless communication base station within a preset time period prior to the current moment. For example, historical outage status may include, but is not limited to, the number of consecutive historical outages and the type of historical outage (such as full outage or partial outage). Preset outage status can refer to a pre-set base station outage status where a historical battery voltage change curve is deemed valid. Historical battery voltage change curve can refer to the reference battery voltage change curve used by the wireless communication base station in the previous base station outage prediction.

[0053] For example, if the base station's mains power has never been interrupted within six months, then the historical battery voltage change curves of other wireless communication base stations are obtained as the reference battery voltage change curve for the wireless communication base station. If the base station's mains power is interrupted within six months, and there is at most one mains power interruption per day, then the historical battery voltage change curve of the wireless communication base station is obtained as the reference battery voltage change curve. If the base station experiences multiple mains power interruptions within a day, and the battery supply voltage does not drop to zero, then the historical battery voltage change curve of the wireless communication base station prior to that day is obtained as the reference battery voltage change curve, or the reference battery voltage change curve is recalculated, such as using the battery supply information during the first battery discharge of that day or historical battery supply information prior to that day. If a base station experiences multiple mains power interruptions within a day, and there are instances where the battery supply voltage drops to zero, then the reference battery voltage change curve is recalculated using the battery supply information corresponding to the most recent battery supply voltage drop to zero.

[0054] As an optional implementation of this disclosure, the battery power supply start voltage of the wireless communication base station is determined based on the supply voltage and the base station power outage voltage. Specifically, it may include: when the voltage difference between a number of consecutive adjacent supply voltages before the base station power outage voltage is detected meets the preset voltage drop condition of the wireless communication base station, the first supply voltage among the consecutive adjacent supply voltages is determined as the battery power supply start voltage of the wireless communication base station.

[0055] In this embodiment of the disclosure, adjacent power supply voltages can refer to continuously collected discrete power supply voltages. The preset voltage drop condition can refer to a pre-set condition for determining when the power supply head switches from AC mains power to battery power.

[0056] Specifically, after determining the base station's mains power outage through the base station's outage voltage, the system searches back in history for the time when the base station's power outage is closest to the normal voltage value (i.e., the mains power supply voltage) and the voltage shows a decreasing trend. This time is then determined as the start time of battery power supply, thereby determining the start voltage of battery power supply corresponding to the start time of battery power supply.

[0057] It should be noted that if the base station power outage is not determined by the base station power outage voltage, but instead the power supply voltage is judged directly based on the preset voltage drop condition, there may be cases where the power supply voltage fluctuates and the power supply voltage meets the preset voltage drop condition even when the mains power is not interrupted. This could lead to the incorrect determination of the battery power supply start voltage that does not exist when the mains power is not interrupted, further improving the accuracy of wireless communication base station outage prediction.

[0058] S130. Based on the reference battery voltage change curve, the battery power supply start voltage, and the wireless communication base station shutdown voltage, determine the wireless communication base station shutdown information.

[0059] In this embodiment of the disclosure, the shutdown voltage may refer to the voltage at which a base station causes a step-by-step shutdown of its service functions due to a voltage drop. The shutdown voltage may include the voltage corresponding to partial shutdown and the voltage corresponding to complete shutdown. Shutdown information may refer to the shutdown time associated with the wireless communication base station.

[0060] Specifically, the starting voltage of the battery power supply is substituted into the reference battery voltage change curve to determine the starting position of battery power supply in the curve, and this position is correlated with the starting time of battery power supply. The shutdown voltage of the wireless communication base station is then substituted into the reference battery voltage change curve to determine the shutdown position of the base station in the curve. Based on the correlation between the shutdown position of the base station in the curve and the established position-time relationship, the shutdown time of the wireless communication base station is determined.

[0061] As an optional implementation of this disclosure, the shutdown information of the wireless communication base station is determined based on the reference battery voltage change curve, the battery power supply start voltage, and the shutdown voltage of the wireless communication base station. Specifically, this may include: substituting the battery power supply start voltage and the first shutdown voltage into the reference battery voltage change curve to obtain the first shutdown duration of the wireless communication base station during the current mains power outage and battery power supply period; and substituting the battery power supply start voltage and the second shutdown voltage into the reference battery voltage change curve to obtain the second shutdown duration of the wireless communication base station during the current mains power outage and battery power supply period.

[0062] In this embodiment of the disclosure, the service outage information may further include the service outage duration. The service outage duration can be understood as the battery discharge duration. The first service outage voltage is the voltage corresponding to partial service outage. The first service outage duration may refer to the duration from the start of battery power supply to the first power-off of the base station. The second service outage voltage is the voltage corresponding to full service outage. The second service outage duration may refer to the duration from the start of battery power supply to the second power-off of the base station.

[0063] Specifically, the battery power supply start voltage and the first outage voltage are substituted into the reference battery voltage change curve to obtain the battery power supply start position and the first outage position in the curve. The time difference between the two positions is determined as the first outage duration of the wireless communication base station during this mains power outage and battery power supply period.

[0064] Substituting the battery power supply start voltage and the second shutdown voltage into the reference battery voltage change curve, we obtain the battery power supply start position and the second shutdown position in the curve. The time difference between the two positions is determined as the second shutdown duration of the wireless communication base station during this mains power outage and battery power supply period.

[0065] The technical solution of this invention obtains the power supply voltage of the wireless communication base station; when the power supply voltage is detected to be the base station power outage voltage, it obtains the reference battery voltage change curve of the wireless communication base station, and determines the battery power supply start voltage of the wireless communication base station based on the power supply voltage and the base station power outage voltage, thereby avoiding misjudgment of mains power outage due to power supply voltage fluctuations, and performing effective base station outage prediction when the mains power supply of the wireless communication base station is accurately determined; based on the reference battery voltage change curve, the battery power supply start voltage, and the wireless communication base station outage voltage, the outage information of the wireless communication base station is determined, thus eliminating the need to predict base station outage based on manual experience, and dynamic prediction of wireless communication base station outage can be achieved by using the reference battery voltage change curve and voltage, thereby improving the efficiency and accuracy of wireless communication base station outage prediction.

[0066] Example 2

[0067] Figure 2This is a flowchart of a wireless communication base station outage prediction method provided in Embodiment 2 of the present invention. Based on the above embodiments, this embodiment describes in detail the process of obtaining the reference battery voltage change curve of the wireless communication base station. Explanations of terms that are the same as or corresponding to those in the above embodiments are not repeated here. Figure 2 As shown, the method includes:

[0068] S210. Obtain the power supply voltage of the wireless communication base station.

[0069] S220. When the power supply voltage is detected to be the base station power outage voltage, obtain the preset battery voltage change function of the wireless communication base station.

[0070] In this embodiment of the disclosure, the preset battery voltage change function can refer to a pre-set battery voltage discharge function that conforms to the battery discharge law. For example, the preset battery voltage change curve shows a certain linear relationship between the battery discharge voltage value and time, such as... There are two parameters to be determined. Represents the intercept. Represents the slope.

[0071] It should be noted that after the mains power to the base station is interrupted, the battery begins to discharge. Based on the difference between the mains supply voltage and the battery supply voltage, the initial discharge voltage and time are obtained. Over time, the base station battery discharge voltage values ​​and corresponding time data are saved to a database, forming a series of voltage values ​​that change over time. The required time-series voltages are extracted from the database, fluctuating around a certain straight line at various time points; the curve plotted from these values ​​over time represents the battery discharge curve for each site. Using a function differentiation algorithm, modeling can be performed using the recorded voltage series values. Analysis of these data reveals a linear relationship between the battery discharge voltage and time.

[0072] For example, based on the difference between the mains power supply voltage and the battery power supply voltage after a mains power outage, the supply voltage during battery power supply is identified and analyzed. In the network management system, the base station main equipment supply voltage data is extracted. Based on the difference between mains power supply and battery power supply, the battery power supply time period can be distinguished. This example mainly predicts the time period when the battery supplies power alone; the data required for verification is the parameters when the battery supplies power after a mains power outage. When the base station is supplied with mains power, the voltage value is generally above 52V; when the mains power is interrupted and the battery supplies power, the initial supply voltage is around 49V (±1V), and gradually decreases over time.

[0073] S230. Based on the battery power supply information and the preset battery voltage change function during the current power outage and battery power supply of the wireless communication base station, determine the reference battery voltage change curve of the wireless communication base station.

[0074] The battery power supply information includes: the battery power supply start voltage, the battery power supply start time corresponding to the battery power supply start voltage, the battery power supply time and battery power supply voltage within a preset time after the battery power supply start time.

[0075] In this embodiment of the disclosure, the battery power supply information may also be the battery power supply information that the wireless communication base station marked as valid during the last mains power outage and battery power supply.

[0076] Specifically, for the battery power supply information obtained from recording with equal precision... Group data ( ), The value is accurate; all errors are only related to... Related. The following uses the function differentiation method to fit the recorded battery power supply information into a straight line. Based on the idea of ​​function differentiation, the formula for the sum of squared errors from the measured point to the accurate value is: According to the extremum theorem, the error equation attains an extremum where the first derivative equals zero. Therefore, we can determine the extremum for each of its approximate values. and Differentiate: Based on the derivative, solve... , The value minimizes the error function. Therefore: .

[0077] For example, in order to improve the accuracy and efficiency of the calculation, we can let: , Substituting A, B, C, and D into the above solution, we get: Therefore, based on the substituted polynomial, we can obtain... , for: .

[0078] Specifically, the n sets of voltage and time series data (i.e., battery power supply information) during the battery discharge period in the equipment room when the base station is powered off are substituted into the obtained data. This will give you the voltage count and time series data for each group. Value, and thus Find the average, that is At the same time Find the average, that is This allows us to obtain the relationship between the discharge voltage and discharge time during the corresponding battery discharge period, i.e. (This is equivalent to obtaining a reference battery voltage change curve).

[0079] For example, after a power outage at the base station, if the equipment room battery continues to supply power, the base station will undergo a primary power-down and a secondary power-down as the supply voltage decreases. By substituting the primary and secondary power-down voltage thresholds configured for each site into the reference battery voltage change curve, the battery power supply duration (i.e., service outage information) of the corresponding equipment room base station under that set of thresholds can be accurately calculated.

[0080] S240. Based on the power supply voltage and the base station power outage voltage, determine the battery power supply start voltage of the wireless communication base station.

[0081] S250. Based on the reference battery voltage change curve, the battery power supply start voltage, and the wireless communication base station shutdown voltage, determine the wireless communication base station shutdown information.

[0082] The technical solution of this invention obtains a preset battery voltage change function for a wireless communication base station. Different base stations may have different battery brands, models, service life, health status, current load (power consumption of connected devices), and ambient temperatures. This means their discharge characteristics (such as discharge curves) will also differ. A customized battery voltage change curve needs to be determined for each base station to further improve the accuracy of base station outage prediction. Based on the battery power supply information of the wireless communication base station during a mains power outage and battery power supply, and the preset battery voltage change function, a reference battery voltage change curve for the wireless communication base station is determined. This curve comprehensively considers the inherent characteristics of the base station's battery and the current actual operating conditions, resulting in a prediction accuracy far higher than using a general curve. The battery power supply information includes: the battery power supply start voltage, the battery power supply start time corresponding to the start voltage, the battery power supply time within a preset time after the start time, and the battery power supply voltage.

[0083] Optionally, embodiments of the present invention also provide two types of recorded power supply voltage data. One type is when the mains power is interrupted, the battery discharge voltage drops sequentially to the first power-off voltage, the second power-off voltage, and the voltage zero; the other type is when the mains power is interrupted, but before the battery discharge voltage drops to the voltage zero, there is generator power supply or mains power is restored.

[0084] Figure 3 An example graph showing the discharge voltage variation curve of a base station battery is provided. See also... Figure 3 The red line segment represents the reference battery voltage change curve. When the voltage difference between the wireless communication base station's supply voltage and the mains supply voltage meets the preset base station power outage conditions, it indicates that the base station is powered down, and the base station power outage time corresponding to the base station power outage voltage is determined. Figure 3(Middle orange dot). After confirming a power outage at the base station, look backwards for the moment closest to the normal voltage value and where the voltage shows a decreasing trend, i.e., the moment T1 when battery power supply begins (…). Figure 3 (Middle purple dot).

[0085] In this optional embodiment, for Figure 3 The purple line segment represents the predicted battery discharge time in the case of a mains power outage and base station outage. When the mains power to the equipment room is interrupted for a period of time, the base station goes out of service (receives a base station outage alarm). The battery discharge time T = T2 - T1 (T2 is the time when the base station's outage alarm occurred in the current time period). While calculating the battery discharge time, the station's Vn value needs to be updated, i.e., the voltage value at which the voltage dropped to its last known value (which can be understood as the most recent non-zero voltage value), as the latest Vn. This latest Vn is then synchronously updated to other base stations with normal voltage values ​​within the same range that have not experienced outages.

[0086] In this optional embodiment, for Figure 3 The blue line segment represents a situation where mains power is interrupted but service is not terminated. The battery discharge duration can be predicted by referencing the battery voltage change curve. After a period of mains power interruption, the voltage gradually returns to normal (i.e., service is not terminated). Data from the main equipment manufacturer's network management system reveals a linear relationship between battery discharge voltage and time, assumed to be: V = KT + B. The slope is calculated as: k1 = (V2 - V1) / (T2 - T1)...kn = [Vn - V(n-1)] / [Tn - T(n-1)]. The condition for voltage recovery is determined by a continuous half-hour voltage increase; that is, when kt > 0 and k(t+1) > 0 at a certain moment, it indicates mains power recovery, and subsequent k values ​​are not calculated. The K value of the fitted curve (equivalent to the reference battery voltage change curve) is calculated. Here, the K value is the average of multiple negative k values ​​within the blue line segment. The voltage value at which the base station goes out of service is determined. Following the fitted curve, the base station will go out of service when its voltage Vn drops to the set initial power-down voltage value. The set initial power-down voltage value may differ for different sites. The battery discharge time is T = (Tn - T1) = (Vn - V1) / K.

[0087] It should be noted that after calculating the base station battery discharge duration T and the reference battery voltage change curve, when the base station meets the preset base station power outage conditions again within six months, the time T1 of the base station mains power interruption is found. If the base station mains power has never been interrupted within six months, the battery discharge duration needs to be recalculated. Monitor whether the base station goes out of service within ±60 minutes of a power outage time X (i.e., whether a base station outage alarm is received). If it goes out of service, update the status of the base station to "out of service within the predicted range"; otherwise, mark it as "out of service within the predicted range".

[0088] For example, the battery discharge duration T update mechanism is as follows: First, when the base station battery discharge duration is calculated under the scenario where the battery discharge voltage drops to zero after a mains power outage and there is generator power supply or mains power restoration, then when the base station goes out of service again, the battery discharge duration needs to be updated to the battery discharge duration at the time of base station outage as the subsequent predicted duration. However, the battery discharge duration before the update also needs to be retained for traceability, but it will not be included in subsequent calculations. Second, if the base station goes out of service multiple times within six months of the first calculated battery discharge duration, the battery discharge duration T needs to be recalculated each time an outage occurs, and the difference Tx between the current outage and the previous outage needs to be calculated. If Tx is greater than or equal to 120 minutes, all T values ​​are discarded, and the discharge duration is recalculated for prediction when the conditions are met again. If Tx is less than 120 minutes, the average of the discharge duration at each outage needs to be used as the new discharge duration T (i.e., calculating the average value). Third, if the base station does not experience service outage within six months of the initial calculated discharge duration, the discharge duration needs to be recalculated. The original discharge duration is retained but not included in subsequent calculations. Fourth, if the base station experiences service outage outside the predicted range of ±60 minutes at time X for six consecutive months (i.e., the base station status remains within the predicted range without outage for six consecutive months), the battery discharge duration also needs to be recalculated.
