Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a base station energy-saving shutdown method, device, and storage medium. Background Art

[0002] In mobile communication networks, the proportion of energy consumption of wireless networks is gradually increasing. Among the energy consumption structures of wireless networks, the energy consumption of base station equipment accounts for the highest proportion. Therefore, base station energy saving is the basis of energy saving in wireless networks.

[0003] In order to achieve energy saving of base stations, many energy-saving methods have been proposed in the existing technology. The basic principle of these methods is to monitor the business load of the base station, determine the network idle time of the base station, and shut down some hardware resources of the base station when the network is idle, such as symbol shutdown, channel shutdown and cell shutdown.

[0004] Because different energy-saving methods shut down different hardware resources at the base station, the energy-saving benefits achieved are also different, and the corresponding service performance is also different. For example, in the symbol-off state, the base station's transmission delay will increase, and the impact on terminal service performance is limited to the potential inability to meet low-latency service requirements, but the base station's energy-saving benefits are the lowest; in the channel-off state, the energy-saving benefits are higher than those of symbol-off, but the base station's maximum transmission rate and coverage radius will be reduced, and it may not meet service rate requirements; in the cell-off state, the base station's energy-saving benefits are the highest, but the terminal will not be able to access the network normally and will need to reconnect to other adjacent cells that are not shut down. Due to differences in cell capabilities, the terminal's service performance is difficult to maintain consistency. Therefore, the existing energy-saving method that determines the base station's hardware resource shutdown based on service load cannot save energy while ensuring terminal service performance. Summary of the Invention

For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0091] The exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0092] First, the relevant concepts or terms involved in this application are explained:

[0093] Symbol shutdown: refers to the use of the absence of data in some frames as a trigger condition to shut down the power amplifier in these frame periods. That is, all RF channels of the base station are shut down during the idle symbol time when there is no business data transmission, and all RF channels are turned on during the symbol time when there is business data transmission.

[0094] Channel shutdown: refers to the use of business volume in the cell as a trigger condition. If a certain threshold is met, the cell base station will be switched from multiple-input and multiple-output to single-input and multiple-output. When the base station business load is low, some of the base station's RF channels will be shut down to save base station energy consumption. In layman's terms, if there were originally 64 channels, they may become 32 channels or 16 channels according to the business volume, but 64 antennas will still be used for transmission. This will reduce the data throughput of the base station and reduce the configuration at the same time, because turning off the power amplifier of one or more channels will lead to a decrease in output signal energy.

[0095] Cell shutdown: refers to judging the business volume of each base station in the configuration area, using the base station with lower business load as an energy-saving base station, and shutting down all radio frequency channels to achieve the purpose of energy saving. It is mainly used in scenarios where multiple base stations are configured at the same time in the same area. One base station is used as a configuration layer base station, and the other base stations are planned as capacity layer base stations. There is a same configuration relationship between the base stations in the area. In order to avoid the impact of cell shutdown on the business in the configuration area, it is necessary to configure a compensation base station for the energy-saving base station to be shut down. Before the cell is shut down, the users under the base station to be shut down are migrated to the compensation base station through switching to keep the business connection uninterrupted.

[0096] Physical Resource Block (PRB): refers to the resources of 12 consecutive carriers in the frequency domain.

[0097] Radio Resource Control (RRC) protocol: It manages, controls, and schedules radio resources through specific strategies and methods. It aims to maximize the use of limited radio network resources while meeting quality of service requirements, ensuring that services reach the planned configuration area and maximizing service capacity and resource utilization.

[0098] Recurrent Neural Network (RNN): refers to a type of recursive neural network that takes sequence data as input, performs recursion in the direction of sequence evolution, and all nodes (recurrent units) are connected in a chain.

[0099] The ARIMA (Autoregressive Integrated Moving Average) model, also known as the ARIMA (Autoregressive Integrated Moving Average) model (moving can also be called sliding), is one of the time series forecasting and analysis methods.

[0100] The Long-Short Term Memory (LSTM) model is a special RNN model designed to address the gradient dispersion problem in RNN models. In traditional RNNs, when time is long, the residual error that needs to be propagated decreases exponentially, resulting in slow updates of network weights and an inability to reflect the long-term memory effect of the RNN. Therefore, a storage unit is required to store the memory.

[0101] Prophet model: refers to a time series forecasting program that is good at processing large-scale commercial time series data with seasonal characteristics.

[0102] Network slicing: This refers to an on-demand networking method. In 5G scenarios, it can be divided into three types of slicing: eMBB slicing, uRLLC slicing, and mMTC slicing. eMBB slicing primarily includes cloud gaming sub-slices, virtual reality sub-slices, and smartphone sub-slices, which enhance mobile broadband communications. uRLLC slicing includes autonomous driving sub-slices, industrial control sub-slices, and video surveillance sub-slices, which can be considered high-reliability, low-latency communications. mMTC slicing is a type of massive machine-type communication, covering smart parking sub-slices, automatic meter reading sub-slices, and smart agriculture sub-slices.

[0103] Reference Signal Received Power (RSRP): A key parameter in the network that represents wireless signal strength and a physical layer measurement requirement. It represents the signal strength measurement value of a cell and is the average of the received signal power across all resource elements (REs) carrying the reference signal within a symbol.

[0104] In the energy consumption structure of wireless networks, the energy consumption of base station equipment accounts for the highest proportion. Therefore, base station energy saving is the basis of wireless network energy saving. Existing base station energy-saving technologies mainly include symbol shutdown, channel shutdown and cell shutdown. However, when determining the energy-saving shutdown method, the existing technology only considers the business load size of the base station, and does not consider the terminals and business needs within the base station configuration area, and cannot guarantee the business performance of the terminal while saving energy. The base station energy-saving shutdown method provided in this application determines the energy-saving shutdown method by obtaining the first business volume prediction value, the second business volume prediction value, the target terminal number prediction value and the target compensation cell corresponding to the target base station, that is, the energy-saving shutdown method of the base station is determined according to the terminal demand and business demand, while reducing the energy consumption of the base station, meeting the business performance requirements of the terminal, and is intended to solve the above technical problems of the prior art.

[0105] Figure 1 Schematic diagram of the application scenario of the base station energy-saving shutdown method provided in the embodiment of this application. Figure 1 As shown, for the target base station 101 that needs energy saving, the cell configured by the target base station 101 is the target service cell 102, and the terminal connected to the target base station 101 in the edge area of ​​the target service cell 102 is the target terminal 103, that is, the target terminal 103 is a terminal that may be connected to or disconnected from the target base station 101 at any time, and the cells configured by the adjacent base stations around the target service cell 102 are adjacent cells 104, and among the adjacent cells 104, the adjacent cell 104 that may replace the target service cell 102 at any time to connect to the target terminal 103 is the target compensation cell 105.

[0106] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0108] S201. At a target time, obtain a first traffic volume prediction value, a second traffic volume prediction value, a target terminal number prediction value, and a target compensation cell corresponding to a target base station.

[0109] Among them, the first business volume prediction value is used to represent the demand prediction value of low-latency business in the target service cell configured by the target base station; the second business volume prediction value is used to represent the demand prediction value of high-speed business in the target service cell; the target terminal number prediction value is used to represent the predicted value of the number of target terminals in the coverage edge area of ​​the target service cell; the target compensation cell is used to represent the adjacent cell that matches the cell capability parameters of the target service cell; the preset period is multiple periods divided by historical time periods.

[0110] Specifically, the target time is a time when the traffic load is relatively low.

[0111] Furthermore, when judging whether the selected target base station needs to save energy, it is first necessary to obtain the current service performance of the target base station, that is, whether the service of the current base station is busy. There are two main parameter values ​​in the service performance, namely, the demand for low-latency services and high-speed services of terminals in the target service cell corresponding to the target base station; among them, the demand for low-latency services and high-speed services can be determined based on the number of connections of the terminal to the corresponding service.

[0112] Secondly, it is also necessary to obtain the connection status of terminals in the edge area of ​​the target service cell, that is, whether there are many terminals in the edge area. Therefore, it is necessary to take the terminals in the edge area as target terminals and count the number of target terminals.

[0113] Thirdly, in order to ensure that the terminal can still enjoy the service after the target base station is shut down, it is necessary to confirm in advance before shutting down whether the adjacent cells where the surrounding base stations are located can serve as the target compensation cells for the terminal.

[0114] Since the service usage of terminals in the target service cell configured by the target base station is usually relatively stable, by performing segmented statistics on the service usage in the historical period according to the preset period, the service demand pattern of the terminals in the target service cell in the historical period can be obtained. According to the service demand pattern in the historical period, the possible demand of the terminals in the future period can be predicted, that is, the first service volume prediction value, the second service volume prediction value, and the target terminal number prediction value, and then before the energy-saving event occurs, the energy-saving operation mode of the base station can be pre-selected.

[0115] S202: Determine whether to control the target base station to perform a symbol-off operation according to the first traffic volume prediction value and a first threshold.

[0116] Specifically, at the target time, the first traffic volume prediction value is the predicted demand for low-latency services at the target time. When the first traffic volume prediction value is less than a first threshold, it indicates that low-latency services are relatively low. Since symbol shutdown increases the transmission delay of the target base station but does not affect services other than low-latency services, the target base station is determined to perform symbol shutdown at this time to save energy.

[0117] Preferably, the judgment process is performed at the first target moment, which is the moment when the service load of the target service cell is less than the preset first shutdown threshold. The service load level at this time is relatively high, and the service load includes the average PRB utilization rate of the target base station in the historical period before the target moment, the average number of RRC connected users and / or the average service traffic volume.

[0118] S203: Determine whether to control the target base station to perform a channel shutoff operation according to the second traffic volume prediction value and the second threshold, the target terminal number prediction value and the third threshold.

[0119] Specifically, at the target time, the second traffic volume prediction value is the predicted demand for high-rate traffic at the target time. When the second traffic volume prediction value is less than the second threshold value and the target terminal number prediction value is less than the third threshold value, this indicates that there is less high-rate traffic and fewer terminals in the target service cell edge area. Since the maximum transmission rate of the target base station will decrease and the configured cell range will also decrease after the channel is shut down, compared to the symbol shutdown operation, the channel shutdown method deactivates more resources and is more energy-efficient. Therefore, when there is less high-rate traffic and fewer terminals in the target service cell edge area, confirming that the target base station performs the channel shutdown operation can achieve greater energy-saving benefits without affecting the service performance of most terminals.

[0120] Preferably, the judgment process is performed at the second target moment, the second target moment is the moment when the business load of the target service cell is less than the preset second shutdown threshold, the preset second shutdown threshold is greater than the preset first shutdown threshold, and the business load level at this time is in the middle.

[0121] S204: Determine whether to control the target base station to perform a cell shutdown operation based on the first traffic volume prediction value and the first threshold, the second traffic volume prediction value and the second threshold, the target terminal number prediction value and the third threshold, and the target compensation cell.

[0122] Specifically, at the target moment, when the first business volume prediction value is less than the first threshold, and the second business volume prediction value is less than the second threshold, and the target terminal number prediction value is less than the third threshold, and there is a target compensation cell, it indicates that the number of low-latency services, high-speed services and edge terminals under the target service cell is relatively small, and there is a target compensation cell that matches the target terminal requirements. Then, the cell shutdown state can be entered, and the terminals within the target service cell can be migrated to the target compensation cell. In this way, the terminal service performance requirements can be met by migrating the terminal under the target service cell to the target compensation cell, and the energy saving effect of the target base station can be maximized by cell shutdown, thereby obtaining more energy saving benefits compared to symbol shutdown or channel shutdown.

[0123] Preferably, the judgment process is performed at the third target moment, which is the moment when the business load of the target service cell is less than the preset third shutdown threshold, and the preset third shutdown threshold is greater than the preset second shutdown threshold. At this time, the business load level is relatively low.

[0124] The method provided in this embodiment obtains, at a target time, a first traffic volume prediction value, a second traffic volume prediction value, a target terminal number prediction value, and a target compensation cell corresponding to a target base station; determines, based on the first traffic volume prediction value and a first threshold, whether to control the target base station to perform a symbol shutdown operation; determines, based on the second traffic volume prediction value and a second threshold, the target terminal number prediction value and a third threshold, whether to control the target base station to perform a channel shutdown operation; determines, based on the first traffic volume prediction value and the first threshold, the second traffic volume prediction value and the second threshold, the target terminal number prediction value and the third threshold, and the target compensation cell, whether to control the target base station to perform a cell shutdown operation, and determines different base station energy-saving shutdown modes according to different terminal requirements and service requirements, thereby reducing base station energy consumption while meeting terminal service performance requirements.

[0125] The base station energy-saving shutdown method of the present application is described in detail below with reference to a specific embodiment.

[0126] Figure 3 Schematic diagram of the base station energy-saving shutdown method provided in the embodiment of the present application Figure 2 .like Figure 3 As shown, the method includes:

[0127] S301. At a target moment, obtain a first service volume, a second service volume, and the number of target terminals corresponding to the target base station in each preset period within a historical period.

[0128] Among them, the first business volume is used to represent the demand for low-latency services in the target service cell; the second business volume is used to represent the demand for high-speed services in the target service cell; and the target terminal number is used to represent the number of target terminals in the edge area covered by the target service cell.

[0129] Specifically, the historical business data and historical terminal data of the target base station before the target time are obtained. In order to facilitate the prediction of the business rules of the target base station, the obtained historical business data and historical terminal data are divided according to preset periods. Multiple groups of data arranged in chronological order within the same preset period can be obtained, that is, the first business volume, second business volume and number of target terminals corresponding to the target base station in each preset period.

[0130] S302: The target base station sends a cell capability parameter request message to the base station where its corresponding adjacent cell is located at the target time.

[0131] Among them, the cell capability parameter request message carries the target service cell identifier and corresponding cell capability parameters configured by the target base station. The cell capability parameters include the network standard, frequency band, slice type and service type supported by the cell.

[0132] S303: Obtain a cell capability parameter indication message fed back by the base station where the neighboring cell is located based on the cell capability parameter request message, and execute S304 or S306 or S308.

[0133] The cell capability parameter indication message carries the neighboring cell identifier and the corresponding cell capability parameter.

[0134] Specifically, base stations between adjacent cells can exchange information. If the target base station wants to perform cell shutdown, it must first ensure that the base stations of the adjacent cells can meet the current terminal service needs of the target base station. Therefore, it is necessary to obtain the cell capability parameters of the base stations where the adjacent cells are located through information exchange.

[0135] S304: Determine a predicted value of the first traffic volume corresponding to the target base station at the first target moment using a preset first prediction model according to the first traffic volume corresponding to the target base station in each preset period within the historical period.

[0136] The first target time is used to indicate the time when the service load of the target serving cell is less than a preset first shutdown threshold.

[0137] Specifically, the first prediction model is a time series model that reflects the corresponding relationship between each preset period and the first traffic volume, such as a PROPHET, ARIMA, LSTM, or neural network model. The first prediction model is trained based on the first traffic volume data for each preset period in the historical time period. This improves the first prediction model and further predicts the first traffic volume forecast value for the target base station in the future period after the first target time.

[0138] S305: If the first traffic volume prediction value is less than the first threshold, control the target base station to perform a symbol-off operation. End.

[0139] Specifically, when the service load of the target service cell reaches the preset first shutdown threshold, it indicates that the service demand has decreased. At this time, the first service volume prediction value obtained is the target base station's demand for low-latency services at future times. When it is less than the first threshold, it means that the terminal's demand for low-latency services has also decreased. At this time, performing the symbol shutdown operation can save energy without affecting terminal demand.

[0140] S306. According to the second traffic volume corresponding to the target base station in each preset period within the historical period, a preset second prediction model is used to determine a second traffic volume prediction value and a target terminal number prediction value corresponding to the target base station at a second target moment.

[0141] The second target time is used to indicate the time when the service load of the target serving cell is less than a preset second shutdown threshold, and the preset second shutdown threshold is less than the preset first shutdown threshold.

[0142] Specifically, the second prediction model is a time series model that reflects the corresponding relationship between each preset period, the second traffic volume, and the target number of terminals, such as a PROPHET, ARIMA, LSTM, or neural network model. The second prediction model is trained based on data from the second traffic volume and target number of terminals within each preset period of the historical time period. This improves the second prediction model and enables prediction of the second traffic volume and target number of terminals for the target base station in future time periods after the second target moment.

[0143] S307: If the second traffic volume prediction value is less than the second threshold value, and the target terminal number prediction value is less than the third threshold value, control the target base station to perform a channel shutoff operation. End.

[0144] Specifically, when the service load of the target service cell reaches the preset second shutdown threshold, since the preset second shutdown threshold is less than the preset first shutdown threshold, it indicates that the service demand has further decreased. At this time, the obtained second service volume forecast value and target terminal number forecast value are the target base station's demand for high-speed services at future times and the terminal number forecast value within the cell range. When the second service volume forecast value is less than the second threshold and the target terminal number forecast value is less than the third threshold, it indicates that the high-speed service demand and edge terminal access demand have further decreased. At this time, performing the channel shutdown operation can further save energy consumption without affecting terminal demand.

[0145] S308. Based on the number of target terminals corresponding to the target base station in each preset period within the historical period, a preset third prediction model is used to determine the first traffic volume prediction value, the second traffic volume prediction value, and the target terminal number prediction value corresponding to the target base station at the third target moment.

[0146] Among them, the third target moment is used to indicate the moment when the service load of the target service cell is less than the preset third shutdown threshold; the preset second shutdown threshold is greater than the preset third shutdown threshold; the service load includes the average value of physical resource utilization, the average value of the number of wireless resource control protocol connected users and / or the average value of service traffic in the historical period before the target moment; the historical period is the period before the target moment.

[0147] Specifically, the third prediction model is a time series model that reflects the corresponding relationship between each preset period and the first traffic volume, the second traffic volume, and the target terminal count, such as a PROPHET, ARIMA, LSTM, or neural network model. The third prediction model is trained based on the data of the first traffic volume, the second traffic volume, and the target terminal count within each preset period of the historical period. This improves the third prediction model and enables prediction of the first traffic volume, the second traffic volume, and the target terminal count for the target base station in future periods after the third target time.

[0148] S309. Determine the target compensation cell of the target base station at the target time according to the network standard, frequency band, slice type, and service type supported by the cell in the cell capability parameters.

[0149] Specifically, if the network standard and frequency band supported by the adjacent cell are the same as those supported by the target base station, and the slice type and service type supported by the adjacent cell at the target time include the slice type and service type supported by the target service cell at the target time, then the adjacent cell is determined as the target compensation cell of the target base station at the target time, so that the terminal under the target service cell can still obtain service performance guarantee after migrating to the target compensation cell, thereby meeting the service performance requirements of the terminal.

[0150] Preferably, the slice type supported by the target base station at the target time is the slice type supported by the largest number of terminals in all target service cells during the historical period, and the service type supported by the target base station at the target time is the service type corresponding to the largest number of services of terminals in all target service cells during the historical period.

[0151] For example, the number of terminals in the target service cell is 10, and the corresponding service types are 8. Among them, the slice type supported by 9 target terminals is eMBB slice, the slice type supported by 1 target terminal is uRLLC slice, 7 service types are data services, and 1 service type is voice service. Then it is confirmed that the slice type of the target base station is Embb slice and the service type is data service.

[0152] S310: If the first traffic volume prediction value is less than the first threshold, the second traffic volume prediction value is less than the second threshold, the target terminal number prediction value is less than the third threshold, and the target serving cell has a corresponding target compensation cell, control the target base station to perform a cell shutdown operation. End.

[0153] Specifically, when the service load of the target service cell reaches the preset third shutdown threshold, since the preset third shutdown threshold is less than the preset second shutdown threshold, it indicates that the service demand is further reduced. At this time, the first service volume forecast value, the second service volume forecast value, and the target terminal number forecast value corresponding to the target base station are obtained. When the first service volume forecast value is less than the first threshold, and the second service volume forecast value is less than the second threshold, and the target terminal number forecast value is less than the third threshold, and there is a corresponding target compensation cell, it means that the terminal demand is further reduced and the terminal migration conditions are met. At this time, performing channel cell operations can save energy consumption to the greatest extent without affecting terminal demand.

[0154] It should be noted that at the second target time, the target serving cell can be in both the symbol-off and channel-off states. At the third target time, when the target serving cell enters the cell-off state, it can be considered to be in both the symbol-off and channel-off states. Because different target times correspond to different service load levels, triggering different energy-saving shutdown states, the lower the service load, the higher the degree of hardware resource shutdown in the corresponding energy-saving shutdown state, and the better the energy-saving effect. Conversely, the greater the service load, the lower the degree of hardware resource shutdown in the corresponding energy-saving shutdown state, and the smaller the impact on network configuration, transmission rate, and transmission latency. This allows the terminal's service performance requirements to be met while achieving energy savings.

[0155] The method provided in this embodiment obtains, at the target moment, the first traffic volume, the second traffic volume and the number of target terminals corresponding to the target base station in each preset period within the historical time period; based on the first traffic volume corresponding to the target base station in each preset period within the historical time period, a preset first prediction model is used to determine the first traffic volume prediction value corresponding to the target base station at the first target moment; if the first traffic volume prediction value is less than the first threshold value, the target base station is controlled to perform a symbol shutdown operation, thereby determining the symbol shutdown timing that does not affect the terminal performance when the traffic volume is high.

[0156] On the basis of the above method, the second traffic volume corresponding to the target base station in each preset period within the historical period is used, and a preset second prediction model is used to determine the second traffic volume prediction value and the target terminal number prediction value corresponding to the target base station at the second target moment; if the second traffic volume prediction value is less than the second threshold, and the target terminal number prediction value is less than the third threshold, the target base station is controlled to perform a channel shutoff operation, so as to achieve the determination of the channel shutoff timing that does not affect the terminal performance when the traffic volume is moderate.

[0157] Based on the above method, the target base station sends a cell capability parameter request message to the base station where its corresponding adjacent cell is located at the target time; obtains the cell capability parameter indication message fed back by the base station where the adjacent cell is located based on the cell capability parameter request message; according to the target number of terminals corresponding to the target base station in each preset period within the historical period, a preset third prediction model is used to determine the first business volume prediction value, the second business volume prediction value, and the target terminal number prediction value corresponding to the target base station at the third target time; according to the network standard, frequency band, slice type and business type supported by the cell in the cell capability parameters, the target compensation cell of the target base station at the target time is determined; if the first business volume prediction value is less than the first threshold, and the second business volume prediction value is less than the second threshold, and the target terminal number prediction value is less than the third threshold, and there is a corresponding target compensation cell in the target service cell, then the target base station is controlled to perform a cell shutdown operation to achieve the determination of the cell shutdown timing that does not affect the terminal performance when the business volume is low.

[0158] Figure 4 Schematic diagram of the target terminal confirmation method provided in the embodiment of the present application. Figure 4 As shown, based on the above embodiment, this embodiment describes the confirmation operation of the target terminal in detail, and the method includes:

[0159] S401. Obtain a signal strength measurement report periodically reported by a terminal in a target serving cell, the terminal's location information, and the target base station's location information, wherein the signal strength measurement report carries a terminal identifier and a target serving cell signal strength measurement value carried in the terminal's signal strength measurement report, and execute S402 or S405.

[0160] Specifically, the target terminal is a terminal whose signal connection with the target base station is unstable, that is, a terminal that is far away from the target base station. Therefore, the prerequisite for obtaining the target terminal is to first obtain the terminal located in the edge area of ​​the target service cell. There are two methods to confirm the edge area terminal. One is to use the signal strength measurement report to regard the terminal with weak signal strength as the edge area terminal. The other is to use the distance to regard the terminal far away from the target base station as the edge area terminal.

[0161] S402: If the target serving cell signal strength measurement value carried in the signal strength measurement report of the terminal is less than a preset signal strength threshold, mark the signal strength measurement report as a target measurement report, and execute S403 or S404.

[0162] S403: Obtain the number of signal strength measurement reports corresponding to the terminal and the total number of signal strength measurement reports corresponding to all terminals within a preset period. If the ratio of the target number of measurement reports corresponding to the terminal to the total number of signal strength measurement reports corresponding to the terminal within the preset period is greater than a preset ratio, determine the terminal as a target terminal. End.

[0163] Specifically, because the weaker the signal, the higher the reporting frequency, and the more measurement reports are sent, the more measurement reports are sent. Therefore, the number of measurement reports can be used to determine the corresponding target terminal.

[0164] S404: Obtain an average signal strength measurement value of the target serving cell corresponding to the terminal within a preset period, and if the average signal strength measurement value of the target serving cell corresponding to the terminal is less than a preset signal strength threshold, determine the terminal as a target terminal. End.

[0165] Specifically, since each terminal has multiple signal strength measurement values, after calculating the average value of the signal strength measurements, the terminal with the smallest average value is selected as the target terminal.

[0166] S405: Determine the distance between the terminal and the target base station based on the location information of the terminal and the target base station, and if the distance between the terminal and the target base station is greater than a preset distance threshold, identify the terminal as the target terminal. End.

[0167] Specifically, the terminal's location information, such as longitude and latitude coordinates, is determined based on the positioning technology of the Global Positioning System (GPS) on the terminal side, or the terminal's location information is obtained based on the base station positioning technology of the target base station. Then, based on the terminal location information and the target base station's location information, the distance between the two is determined, and the terminal whose distance is greater than a preset distance threshold is determined as a target terminal with relatively weak signal strength.

[0168] The method provided in this embodiment obtains a signal strength measurement report periodically reported by a terminal in a target serving cell, the terminal's location information, and the location information of a target base station. The signal strength measurement report carries a terminal identifier and a target serving cell signal strength measurement value carried in the terminal's signal strength measurement report. If the target serving cell signal strength measurement value carried in the terminal's signal strength measurement report is less than a preset signal strength threshold, the signal strength measurement report is marked as a target measurement report. The signal strength measurement value in the signal strength measurement report is used to determine that the terminal with weak signal strength is in an edge area.

[0169] By obtaining the number of signal strength measurement reports corresponding to the terminal and the total number of signal strength measurement reports corresponding to all terminals within a preset period, if the ratio of the target measurement report number corresponding to the terminal to the total number of signal strength measurement reports corresponding to the terminal within the preset period is greater than the preset ratio, the terminal is determined as a target terminal, and the terminal with an unstable connection state is confirmed as a target terminal.

[0170] By obtaining the average signal strength measurement value of the target serving cell corresponding to the terminal within a preset period, if the average signal strength measurement value of the target serving cell corresponding to the terminal is less than a preset signal strength threshold, the terminal is determined as the target terminal.

[0171] By determining the distance between the terminal and the target base station based on the location information of the terminal and the target base station, if the distance between the terminal and the target base station is greater than a preset distance threshold, the terminal is confirmed as the target terminal, and the location information is used to confirm that the terminal at a long distance is the target terminal.

[0172] In an embodiment of the present invention, the electronic device or main control device can be divided into functional modules according to the above method example. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing unit. The above-mentioned integrated unit can be implemented in the form of hardware or in the form of software functional modules. It should be noted that the division of modules in the embodiment of the present invention is schematic and is only a logical functional division. In actual implementation, there may be other division methods.
