Description

A power control method and a power control device

Technical Field

The present application relates to the field of communication technology, and in particular to a power control method and a power control device.

Background Art

With the development of wireless communication technology, a site can deploy multiple communication devices of different communication standards to provide a variety of wireless network services. The electromagnetic radiation intensity generated by such a site has the risk of exceeding the electromagnetic radiation standard. With the deployment of 5G equipment, how to control the electromagnetic radiation of the site within the electromagnetic radiation standard has become a concern.

Currently, there is a method for controlling the intensity of electromagnetic radiation, which is roughly as follows: calculate the current electromagnetic radiation intensity of a site based on the working power of non-5G equipment at a site, calculate the allowable working power of the 5G device based on the difference between the electromagnetic radiation standard and the current electromagnetic radiation intensity, and control the power of the 5G device according to the allowable working power.

As the services on non-5G devices migrate to 5G devices, the working power of non-5G devices will decrease. This will cause the working power allocated to non-5G devices to be too high and the working power allocated to 5G devices to be too low, that is, the problem of unreasonable power allocation. Therefore, the above method of controlling the intensity of electromagnetic radiation is difficult to apply to 5G application scenarios.

Summary of the invention

In view of this, the present application provides a power control method and a power control device, which can automatically adjust the power of each communication unit in a site, so as to more effectively utilize the power of the communication unit.

A first aspect provides a power control method, in which a first electric field strength value is obtained; when the first electric field strength value is greater than or equal to a preset electric field strength, a power reduction simulation is performed on the data transmission power of multiple communication units in a target time period, and a second electric field strength value is calculated based on the reduced data transmission power; when the second electric field strength value is less than the preset electric field strength, a command is output; and a power reduction operation is performed within the target time period according to the command.

Among them, the multiple communication units include communication units of different communication formats. Each communication unit is configured with an independent preset data transmission power. Data transmission power refers to the average power of transmitting business data in a time period. The duration of the time period can be set according to actual conditions, and this application does not limit it. Electric field strength is also called electromagnetic radiation intensity. The first electric field strength value is the electric field strength value measured at the measurement point for the site when the multiple communication units of the site are configured with a preset data transmission power. The second electric field strength value is the electric field strength value measured at the measurement point for the site when the multiple communication units of the site are configured according to the reduced data transmission power.

According to this implementation, when the data transmission power of the site is too large, the data transmission power of multiple communication units in the target time period is reduced for simulation, and the data transmission power of the site can be the arithmetic sum or weighted sum of the data transmission power of all communication units. If the electric field strength of the site does not exceed the preset electric field strength under the simulation condition, then after configuration according to the reduced data transmission power, the communication unit can perform data transmission according to the reduced data transmission power during the target time period. In this way, the power of each communication unit can be automatically adjusted and the electric field strength of the site does not exceed the preset electric field strength, thereby ensuring that its electromagnetic radiation intensity is within a safe range.

In another possible implementation, the load of each communication unit in the target period is predicted according to the historical load of the communication unit; the priority of each communication unit is determined according to the prediction result, and the prediction result of each communication unit in the target period is negatively correlated with the priority of the communication unit; and the data transmission power of each communication unit in the target period is simulated by power reduction according to the priority order from high to low. Specifically, the time before the target period can be divided into multiple periods, and the duration of each period is equal to the duration of the target period. The unit of the target period can be but not limited to minutes or hours, which can be set according to actual conditions, and the present application is not limited thereto. Then, a prediction model is trained according to the historical load of each period, and the prediction model is used to predict the load of the target period. The training method can be but not limited to a gradient descent algorithm or a neural network algorithm. The priority of each communication unit is determined according to the load of each communication unit, that is, the lower the load, the higher the priority of the communication unit, and the higher the load, the lower the priority of the communication unit. Prioritize the power reduction simulation for the communication unit with low load, so that the communication unit with high load can use more power, so that the power of the communication unit is allocated according to the load, thereby making full use of the power of each communication unit. Moreover, the method has little or no impact on the service transmission of the site, so that the user experience is not significantly affected or even does not affect the user experience. It should be noted that the order of power reduction simulation for multiple communication units is not limited to from high to low, but can also be from low to high, random order or other order, which is not limited in this application.

In another possible implementation, the data transmission power of each communication unit in the target time period is simulated to be reduced in power, including: under the condition that the communication unit is configured with multiple working frequency bands and each working frequency band includes multiple sub-frequency bands, one working frequency band is selected from the multiple working frequency bands in turn as the target working frequency band, and the load of each sub-frequency band in the target working frequency band in the target time period is predicted according to the historical load of the sub-frequency band; the sub-frequency band with the smallest predicted load is used as the target sub-frequency band; all business loads of the target sub-frequency band in the target time period are transferred to other sub-frequency bands, and the target sub-frequency band and the other sub-frequency bands belong to the same working frequency band; when the target sub-frequency band meets the shutdown condition, the target sub-frequency band is simulated to be shut down during the target time period.

Among them, predicting the load of each sub-band in the target working frequency band within the target time period according to the historical load of the sub-band can be based on a prediction model. The training method of the prediction model can be but is not limited to a gradient descent algorithm and a neural network algorithm. According to this implementation, the load of the target sub-band with the minimum load can be migrated to other sub-bands for transmission, and then the target sub-band is turned off, thereby realizing power reduction simulation. This can have little or no impact on the service transmission of the communication unit. It should be noted that in addition to turning off the sub-band with the minimum load, one or more other sub-bands with smaller loads can also be selected to be turned off.

In another possible implementation, before the target sub-frequency band is simulated and the carrier is turned off during the target period, the power control method also includes: the target sub-frequency band is simulated and the carrier is turned off during the target period; the service quality index of the target working frequency band is obtained; when the service quality index of the target working frequency band meets the preset service quality requirement, it is determined that the target sub-frequency band meets the turn-off condition; when the service quality index of the target working frequency band does not meet the preset service quality requirement, it is determined that the target sub-frequency band does not meet the turn-off condition. In this way, the sub-frequency bands that can be turned off and the sub-frequency bands that cannot be turned off in each communication unit can be identified through simulation, thereby ensuring the service quality of the business when reducing power.

In another possible implementation, the power reduction simulation of the data transmission power of each communication unit in the target time period includes: when the communication unit is configured with multiple beams for data transmission, selecting one beam from the multiple beams in turn as the target beam, and reducing the data transmission power of the target beam in the target time period from a preset first power to a second power; obtaining the service quality index of the target beam; when the service quality index of the target beam meets the preset service quality requirement, configuring the data transmission power of the target beam in the target time period according to the second power. The power control of the beams can be independent of each other. This can reduce the power of one or more beams and ensure the quality of business service.

In another possible implementation, the power reduction simulation of the data transmission power of each communication unit in the target time period includes: reducing the average power of the power amplifier of the communication unit in the target time period from the preset third power to the fourth power; obtaining the service quality index of all working frequency bands of the communication unit; when the service quality index of all working frequency bands of the communication unit meets the preset service quality requirements, configuring the power of the power amplifier of the communication unit in the target time period according to the fourth power. In this way, the power of the power amplifier of the communication unit can be reduced, and the service quality of the business can be guaranteed.

In another possible implementation, the power reduction simulation of the data transmission power of each communication unit in the target time period includes: when the communication unit is configured with multiple working frequency bands, each working frequency band includes multiple sub-frequency bands and the communication unit is configured with multiple beams, one working frequency band is selected from the multiple working frequency bands in turn as the target working frequency band, and the load of each sub-frequency band in the target working frequency band in the target time period is predicted according to the historical load of the sub-frequency band; the sub-frequency band with the smallest predicted load is used as the target sub-frequency band; all business loads of the target sub-frequency band in the target time period are transferred to other sub-frequency bands, and the target sub-frequency band and the other sub-frequency bands belong to the same working frequency band; when the target sub-frequency band meets the shutdown condition, the target sub-frequency band is shut down in the target time period. Simulate carrier shutdown; select one beam from multiple beams in turn as the target beam, and reduce the data transmission power of the target beam in the target time period from the preset first power to the second power; obtain the service quality index of the target beam; when the service quality index of the target beam meets the preset service quality requirements, configure the data transmission power of the target beam in the target time period according to the second power; reduce the average power of the power amplifier of the communication unit in the target time period from the preset third power to the fourth power; obtain the service quality index of all working frequency bands of the communication unit; when the service quality index of all working frequency bands of the communication unit meets the preset service quality requirements, configure the power of the power amplifier of the communication unit in the target time period according to the fourth power. According to this implementation, the carrier shutdown simulation has the least impact on the service quality, the reduction of beam power has the second greatest impact on the service quality, and the power reduction simulation of the power amplifier of the communication unit has the greatest impact on the service quality. According to the above order of implementation, the impact of the power reduction process on the service quality can be minimized.

DETAILED DESCRIPTION

The power control method of the present application can be applied to a site of a wireless communication system. The site may include a processing unit and a communication unit. The processing unit and the communication unit are connected by wire or wirelessly. When the site includes multiple communication units, the multiple communication units may include communication units of different communication formats, such as a remote radio unit (RRU) of a 2G network, an RRU of a 3G network, an RRU of a 4G network, or an active antenna unit (AAU) of a 5G network. The number of processing units may be one or more, and the number of communication units of each communication format may be one or more. It is understandable that each communication unit may also include an antenna unit, and the antenna unit may include one or more antennas.

Referring to Fig. 1, a site may include a processing unit 10, a communication unit 20, and a communication unit 30. The processing unit 10 may be a computing device or a processor in a computing device. The communication unit 20 may be an RRU of a 4G network, and the communication unit 30 may be an AAU of a 5G network.

Hereinafter, the data transmission power of the communication unit 20 is recorded as P ₁ , and the data transmission power of the communication unit 30 is recorded as P ₂ . The data transmission power may be the antenna transmission power.

Optionally, the power density S ₁ of the communication unit 20 is calculated according to the first formula.

The first formula is: S ₁ =P ₁ ×G ₁ /4πR ₁ ² ;

Wherein, _G1 is the power gain of the communication unit 20, in dBi. _R1 is the distance from the measurement point to the antenna of the communication unit 20.

Optionally, the power density S ₂ of the communication unit 30 is calculated according to the second formula.

The second formula is: S ₂ =P ₂ ×G ₂ /4πR ₂ ²

Wherein, _G2 is the power gain of the communication unit 30, in dBi. _R2 is the distance from the measurement point to the antenna of the communication unit 30. The antenna of the communication unit 20 and the antenna of the communication unit 30 can be deployed on the same antenna tower or at a close location, in which case _R1 is similar to or equal to _R2 .

Optionally, the power density S′ of the site is calculated according to the third formula.

The third formula is: S′=S ₁ +S ₂ .

Optionally, the power density S and the electric field strength E satisfy the fourth formula:

The fourth formula is: S=E ² /377.

According to the above formula, after obtaining the distance from the measurement point to the antenna, the power gain, and the antenna transmission power, the electric field strength value of each communication unit can be calculated. According to the above formula and the electromagnetic radiation standard, the maximum allowable power of the site can also be calculated, and the power of each communication unit can be allocated on this basis.

The current power allocation method has the problem of unreasonable power allocation and difficulty in fully utilizing the power of each communication device. The present application discloses a power control method, which can automatically adjust the power of each communication unit in a site, so as to more effectively utilize the power of the communication unit. The following is a detailed description. Referring to FIG. 2, an embodiment of the power control method in the present application includes:

Step 201: Obtain a first electric field strength value.

In this embodiment, the first electric field strength value is the electric field strength value measured at the site at the measurement point when the multiple communication units of the site are configured with a preset data transmission power. The multiple communication units include communication units of different communication standards. For example, the site may include one or more RRUs of a 2G network, one or more RRUs of a 3G network, one or more RRUs of a 4G network, and one or more AAUs of a 5G network, and may also include communication units after 5G.

Each communication unit is configured with an independent preset data transmission power. For example, the preset data transmission power of the RRU of the 4G network is different from the preset data transmission power of the AAU of the 5G network. The data transmission power refers to the average power of transmitting service data in a period of time. The duration of the period can be set according to actual conditions and is not limited in this application.

Step 202: When the first electric field strength value is greater than or equal to the preset electric field strength, a power reduction simulation is performed on the data transmission power of the plurality of communication units in the target time period.

When the first electric field strength value is greater than or equal to the preset electric field strength, it indicates that the electric field strength value of the site is greater than the electromagnetic field radiation standard, and also indicates that the data transmission power of the site is too large, and the data transmission power of the communication unit needs to be reduced. When the first electric field strength value is less than the preset electric field strength, it indicates that the electric field strength value of the site is less than the electromagnetic field radiation standard.

The data transmission power of the site may be the arithmetic sum of the data transmission powers of all communication units, or the data transmission power of the site may be the weighted sum of the data transmission powers of all communication units. The weight of the data transmission power of each communication unit may be set according to actual conditions, and this application does not limit this.

Step 203: Calculate a second electric field strength value according to the reduced data transmission power.

The second electric field strength value is an electric field strength value measured at the site at the measurement point when multiple communication units of the site are configured according to the reduced data transmission power.

Optionally, after the data transmission power of multiple communication units is reduced, the electric field strength value of each communication unit is calculated according to the reduced data transmission power of each communication unit, and then the second electric field strength value is calculated according to the electric field strength value of each communication unit. Alternatively, after the data transmission power of multiple communication units is reduced, the data transmission power of the site is calculated according to the reduced data transmission power of each communication unit, and then the second electric field strength value is calculated according to the data transmission power of the site.

Step 204: Output a command when the second electric field strength value is less than or equal to the preset electric field strength.

The command may be a man-machine language (MML) command. When the second electric field strength value is greater than the preset electric field strength, it indicates that the electric field strength of the site is too large and the power reduction simulation cannot be performed according to the current data transmission power. Specifically, the data transmission power may be further reduced until the electric field strength value calculated according to the reduced data transmission power is less than or equal to the preset electric field strength, and then the command is output.

Step 205: Perform a power reduction operation within the target time period according to the command.

The communication unit performs a power reduction operation within the target period according to the command, and performs data transmission according to the reduced data transmission power. The command is used to make the power reduction operation consistent with the power reduction simulation process.

In this embodiment, when the data transmission power of a site is too large, the data transmission power of multiple communication units in the target time period is reduced for simulation. If the electric field strength of the site does not exceed the preset electric field strength under the simulation condition, then after configuration according to the reduced data transmission power, data transmission can be ensured according to the reduced data transmission power during the target time period. In this way, the power of each communication unit can be automatically adjusted and the electric field strength of the site does not exceed the preset electric field strength, thereby ensuring that its electromagnetic radiation intensity is within a safe range.

In an optional embodiment, performing power reduction simulation on the data transmission power of the plurality of communication units in the target time period includes:

The load of each communication unit in the target period is predicted according to the historical load of the communication unit; the priority of each communication unit is determined according to the prediction result; and the data transmission power of each communication unit in the target period is reduced for simulation in descending order of priority.

In this embodiment, the time before the target period can be divided into multiple periods, and then the prediction model is trained according to the historical load of each period, and the prediction model is used to predict the load of the target period. The duration of each period is equal to the duration of the target period, and the unit of the target period can be minutes or hours, which can be set according to actual conditions and is not limited in this application. The training method can be a gradient descent algorithm, a neural network algorithm, etc.

The prediction result of each communication unit in the target time period is negatively correlated with the priority of the communication unit, that is, the lower the load, the higher the priority of the communication unit, and the higher the load, the lower the priority of the communication unit. Prioritize the power reduction simulation for the communication unit with low load, so that the communication unit with high load can use more power, so as to realize the power allocation of the communication unit according to the load, so as to make full use of the power of each communication unit. In addition, this method has little or no impact on the service transmission of the site, so it has no obvious impact on the user experience or even no impact on the user experience.

It should be noted that the order of performing power reduction simulation on multiple communication units is not limited to from high to low, and can also be from low to high or in a random order, and this application does not limit this.

In the embodiment of the present application, the power reduction simulation of the data transmission power of each communication unit in the target period can be implemented by various methods:

The first method is to shut down the carrier, which can be specifically referred to in the following embodiments:

In an optional embodiment, under the condition that the communication unit is configured with multiple working frequency bands and each working frequency band includes multiple sub-frequency bands, one working frequency band is selected from the multiple working frequency bands in turn as the target working frequency band, and the load of each sub-frequency band in the target working frequency band within the target time period is predicted according to the historical load of the sub-frequency band; the sub-frequency band with the smallest predicted load is used as the target sub-frequency band; all business loads of the target sub-frequency band in the target time period are transferred to other sub-frequency bands; when the target sub-frequency band meets the shutdown condition, the target sub-frequency band is subjected to simulated carrier shutdown during the target time period.

The sub-band is also called a subcarrier. The target sub-band and other sub-bands belong to the same working band. In the process of migrating the service load of the target sub-band, a load threshold can be set for each sub-band. When the load of the sub-band is lower than the load threshold, the service load can be migrated to the sub-band. When the load of the sub-band reaches or exceeds the load threshold, the migration of the service load to the sub-band is stopped.

Optionally, the migration sub-band can be set in order from low to high load, and the migration sub-band is the sub-band to which the service load is migrated. For example, a working frequency band includes 5 sub-bands, and the 5 sub-bands are f1, f2, f3, f4, and f5. The load amounts of the sub-bands are D1, D2, D3, D4, and D5, and D1<D2<D3<D4<D5. According to the method of this embodiment, f1 can be determined as the target sub-band, and the service load of f1 can be migrated to other sub-bands, and the migration order is f2, f3, f4, and f5. Before migrating the service to the next sub-band, it is necessary to make the service load of the previous sub-band reach or exceed the load threshold. If all service loads are migrated to f2 and the load amount of f2 does not exceed the load threshold, then f1 will not migrate the service load to f3, f4, and f5. If the service load needs to be migrated to f3, the service load must first be migrated to f2 so that the load of f2 reaches or exceeds the load threshold.

In this way, for each working frequency band, the data transmission power of the communication unit can be reduced by migrating the service load and shutting down the sub-frequency band, thereby having little or no impact on the service transmission of the communication unit.

In another optional embodiment, before the target sub-frequency band is shut down for simulated carrier during the target time period, the power control method also includes: shutting down the target sub-frequency band for simulated carrier during the target time period; obtaining a service quality indicator of the target working frequency band; when the service quality indicator of the target working frequency band meets the preset service quality requirement, determining that the target sub-frequency band meets the shutdown condition; when the service quality indicator of the target working frequency band does not meet the preset service quality requirement, determining that the target sub-frequency band does not meet the shutdown condition.

The service quality indicator may include one or more of throughput, transmission delay and packet loss rate. When the service quality indicator includes throughput, transmission delay and packet loss rate, it is necessary to simultaneously meet multiple conditions such as throughput greater than or equal to the preset throughput, transmission delay less than or equal to the preset delay or packet loss rate less than or equal to the preset packet loss rate, to indicate that the service quality indicator of the target working frequency band meets the preset service quality requirement, otherwise the service quality indicator of the target working frequency band does not meet the preset service quality requirement.

In this embodiment, the sub-frequency bands that can be turned off and the sub-frequency bands that cannot be turned off in each communication unit can be identified through simulation, thereby ensuring the service quality when reducing power.

The second method is beam power control, which can be specifically referred to in the following embodiments:

In another optional embodiment, when the communication unit is configured with multiple beams for data transmission, one beam is selected from the multiple beams in turn as the target beam, and the data transmission power of the target beam in the target time period is reduced from a preset first power to a second power; the service quality indicator of the target beam is obtained; when the service quality indicator of the target beam meets the preset service quality requirement, the data transmission power of the target beam in the target time period is configured according to the second power.

The second power is less than the first power. The specific values of the first power and the second power can be set according to actual conditions, and this application does not limit them.

In this embodiment, the data transmission power of a beam can be reduced individually, thereby achieving fine-grained power control. By reducing the power of one or more beams, the electric field strength of the site can meet safety standards and ensure the quality of service.

The third method is to reduce the power of the power amplifier, which can be specifically referred to in the following embodiments:

In another optional embodiment, the average power of the power amplifier of the communication unit during the target time period is reduced from a preset third power to a fourth power; the service quality indicators of all working frequency bands of the communication unit are obtained; when the service quality indicators of all working frequency bands of the communication unit meet the preset service quality requirements, the power of the power amplifier of the communication unit during the target time period is configured according to the fourth power.

The fourth power is less than the third power. The specific values of the third power and the fourth power can be set according to actual conditions, and this application does not limit them.

In this embodiment, the power of the power amplifier of the communication unit can be reduced, thereby achieving coarse-grained power control, which can make the electric field strength of the site meet the safety standards and ensure the service quality of the business.

In addition, the data transmission power of each communication unit in the target time period can be reduced by simulating the power reduction, and two or three of the above power reduction simulation methods can be performed in sequence. For example, for a 3G communication unit, the first method can be performed first and then the third method; or, the third method can be performed first and then the first method. For a 4G communication unit or a 5G communication unit, the first method can be performed first and then the second method; or, the first method can be performed first and then the third method; or, the first method can be performed first, then the second method, and then the third method.

It should be noted that the execution order of the multiple power reduction simulation methods is not limited to the above examples, and can also be executed in other orders, which is not limited in this application.

The process of performing power reduction simulation in the order of the first method, the second method, and the third method is described in detail below with an embodiment:

In an optional embodiment, performing power reduction simulation on the data transmission power of each communication unit in the target time period includes:

In the case where the communication unit is configured with multiple working frequency bands, each working frequency band includes multiple sub-frequency bands and the communication unit is configured with multiple beams, one working frequency band is selected from the multiple working frequency bands in turn as the target working frequency band, and the load of each sub-frequency band in the target working frequency band in the target time period is predicted according to the historical load of the sub-frequency band; the sub-frequency band with the smallest predicted load is used as the target sub-frequency band; all business loads of the target sub-frequency band in the target time period are transferred to other sub-frequency bands, and the target sub-frequency band and the other sub-frequency bands belong to the same working frequency band; when the target sub-frequency band meets the shutdown condition, the target sub-frequency band is subjected to simulated carrier shutdown in the target time period;

In this embodiment, for each working frequency band, after the service load of the sub-frequency band with the lowest load is migrated to other sub-frequency bands, the sub-frequency band with the lowest load is then subjected to carrier shutdown simulation. After the sub-frequency band with the lowest load in some or all working frequency bands is shut down, the data transmission power of some or all beams is simulated to be reduced, and then the power amplifier of the communication unit is simulated to be reduced. In this way, the service quality of the communication equipment transmission service can be guaranteed while reducing the power.
