Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a power control method and a power control apparatus.
Background
With the development of wireless communication technology, a station can deploy a plurality of communication devices with different communication systems to provide a plurality of wireless network services. The intensity of the electromagnetic radiation generated by such a station risks exceeding the electromagnetic radiation standards. With the deployment of 5G devices, how to control the electromagnetic radiation of a station within the electromagnetic radiation standard becomes a concern.
One current method of controlling the intensity of electromagnetic radiation is generally as follows: the method comprises the steps of calculating the current electromagnetic radiation intensity of a station according to the working power of non-5G equipment of the station, calculating the allowable working power of the 5G equipment according to the difference value between the electromagnetic radiation standard and the current electromagnetic radiation intensity, and carrying out power control on the 5G equipment according to the allowable working power.
As the service on the non-5G device migrates to the 5G device, the operating power of the non-5G device may be reduced, which may cause the problem that the operating power allocated to the non-5G device is too high and the operating power allocated to the 5G device is too low, i.e. the power allocation is not reasonable, so that the above method for controlling the electromagnetic radiation intensity is difficult to be applied to the 5G application scenario.
Disclosure of Invention
In view of the above, the present application provides a power control method and a power control apparatus, which can automatically adjust the power of each communication unit in a site, thereby more effectively utilizing the power of the communication unit.
A first aspect provides a power control method in which a first electric field strength value is acquired; when the first electric field strength value is larger than or equal to the preset electric field strength value, performing power reduction simulation on the data transmission power of the plurality of communication units in the target time period, and calculating a second electric field strength value according to the reduced data transmission power; outputting a command when the second electric field strength value is smaller than the preset electric field strength; and performing power-down operation within the target time period according to the command.
The plurality of communication units comprise communication units of different communication systems. Each communication unit is configured with an independent preset data transmission power. The data transmission power refers to an average power of transmission service data in a time period, and a duration of the time period may be set according to an actual situation, which is not limited in the present application. The electric field strength is also referred to as the electromagnetic radiation strength. The first electric field strength value is an electric field strength value measured at the station at the measurement point when the plurality of communication units of the station configure a preset data transmission power. The second electric field strength value is an electric field strength value measured at the measurement point to the station when the plurality of communication units of the station are configured in accordance with the reduced data transmission power.
By doing so, in the case that the data transmission power of the station is too large, the data transmission power of the plurality of communication units in the target time period is subjected to power reduction simulation, and the data transmission power of the station may be an arithmetic sum or a weighted sum of the data transmission powers of all the communication units. If the electric field intensity of the station does not exceed the preset electric field intensity under the simulation condition, the communication unit can transmit data according to the reduced data transmission power in the target time period after the configuration according to the reduced data transmission power. Therefore, the power of each communication unit can be automatically adjusted, and the electric field intensity of the station does not exceed the preset electric field intensity, so that the electromagnetic radiation intensity is ensured within a safety range.
In another possible implementation manner, the load amount of each communication unit in a target period is predicted according to the historical load amount of the communication unit; determining the priority of each communication unit according to the prediction result, wherein the prediction result of each communication unit in the target time interval is inversely related to the priority of the communication unit; and performing power reduction simulation on the data transmission power of each communication unit in the target time period according to the priority order from high to low. Specifically, the time before the target time interval may be divided into a plurality of time intervals, the duration of each time interval is equal to the duration of the target time interval, the unit of the target time interval may be, but is not limited to, minutes or hours, and the time interval may be set according to the actual situation, which is not limited in this application. And then training a prediction model according to the historical load amount of each time interval, and predicting the load amount of the target time interval by using the prediction model. The training method may be, but is not limited to, a gradient descent algorithm, a neural network algorithm. The priority of each communication unit is determined according to the load of each communication unit, namely, the lower the load, the higher the priority of the communication unit, and the higher the priority of the communication unit. The power reduction simulation is preferentially carried out on the communication units with low load capacity, so that the communication units with high load capacity can use more power, the power of the communication units is distributed according to the load capacity, and the power of each communication unit is fully utilized. Moreover, the method has little or no influence on the service transmission of the site, so that the user experience is not obviously influenced or even influenced. The order of performing the power down simulation on the plurality of communication units is not limited to the order from high to low, and may be the order from low to high, a random order, or another order, and the present application is not limited thereto.

The prediction of the load of each sub-band in the target working band within the target time period according to the historical load of the sub-band may 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. By the implementation, the load of the target frequency sub-band with the minimum load can be transferred to other frequency sub-bands for transmission, and then the target frequency sub-band is turned off, so that power reduction simulation is realized. This can have little to no impact on the traffic transmission of the communication unit. It should be noted that, besides the sub-band with the minimum load, one or more other sub-bands with smaller load may be selected to be turned off.
In another possible implementation manner, before the target frequency sub-band is turned off by the artificial carrier in the target time period, the power control method further includes: carrying out simulation carrier wave shutoff on the target sub-frequency band in a target time period; acquiring a service quality index of a target working frequency band; when the service quality index of the target working frequency band meets the preset service quality requirement, determining that the target sub-frequency band meets the turn-off condition; and when the service quality index of the target working frequency band does not meet the preset service quality requirement, determining that the target frequency sub-band does not meet the turn-off condition. In this way, the sub-bands which can be switched off and the sub-bands which cannot be switched off in each communication unit can be identified through simulation, so that the service quality can be guaranteed when the power is reduced.
In another possible implementation, the power-down simulating the data transmission power of each communication unit in the target period comprises: under the condition that a communication unit is configured with a plurality of beams for data transmission, one beam is sequentially selected from the plurality of beams as a target beam, and the data transmission power of the target beam in a target time period is reduced from a preset first power to a second power; acquiring a service quality index of a target beam; and 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 interval according to the second power. Wherein the power control of the beams may be independent of each other. This can reduce the power of one or more beams and can guarantee the quality of service of the service.

This can reduce the power of the power amplifier of the communication unit and can guarantee the quality of service of the business.
In another possible implementation, the power-down simulating the data transmission power of each communication unit in the target period comprises: under the condition that a communication unit is configured with a plurality of working frequency bands, each working frequency band comprises a plurality of sub-frequency bands, and the communication unit is configured with a plurality of beams, one working frequency band is sequentially selected from the plurality of working frequency bands to serve as a target working frequency band, and the load capacity of each sub-frequency band in the target working frequency band in a target time period is predicted according to the historical load capacity of the sub-frequency band; taking the predicted sub-frequency band with the minimum load capacity as a target sub-frequency band; transferring all service loads of the target sub-band in the target time period to other sub-bands, wherein the target sub-band and the other sub-bands belong to the same working frequency band; when the target sub-band meets the turn-off condition, carrying out simulated carrier turn-off on the target sub-band in a target time period; sequentially selecting one beam from the plurality of beams as a target beam, and reducing the data transmission power of the target beam in a target time period from a preset first power to a second power; acquiring a service quality index of a target beam; when the service quality index of the target wave beam meets the preset service quality requirement, configuring the data transmission power of the target wave beam in the target time interval according to a second power; reducing the average power of a power amplifier of the communication unit in a target period from a preset third power to a fourth power; acquiring service quality indexes of all working frequency bands of a communication unit; and when the service quality indexes of all the working frequency bands of the communication unit meet the preset service quality requirement, configuring the power of the power amplifier of the communication unit in the target time period according to the fourth power. By the implementation, the influence of carrier turn-off simulation on the service quality is minimum, the influence of beam power on the service quality is reduced for the second time, and the influence of power reduction simulation on the power amplifier of the communication unit on the service quality is maximum. By implementing the above sequence, 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 station of a wireless communication system. A station may comprise a processing unit and a communication unit. The processing unit and the communication unit are connected by wire or wirelessly. When the station includes a plurality of communication units, the plurality of communication units may include communication units of different communication systems, 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 the processing units may be one or more, and the number of the communication units of each communication system may be one or more. It will be appreciated that each communication unit may also include an antenna unit, which may include one or more antennas.
Referring to fig. 1, a station 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 within 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 denoted as P1The data transmission power of the communication unit 30 is denoted as P2The data transmission power may be an antenna transmission power.
Alternatively, the power density S of the communication unit 20 is calculated according to a first formula1。
The first formula is: s1＝P1×G1/4πR1 2；
Wherein G is1In dBi, is the power gain of the communication unit 20. R1To measure the distance of a point to the antenna of the communication unit 20.
Optionally, the power density S of the communication unit 30 is calculated according to a second formula2。
The second formula is: s2＝P2×G2/4πR2 2
Wherein G is2In dBi, is the power gain of the communication unit 30. R2To measure the distance of a point to the antenna of the communication unit 30. The antenna of communication unit 20 and the antenna of communication unit 30 may be deployed on a single tower or in close proximity, where R is1And R2Similar or equal.
Optionally, the power density S' of the station is calculated according to a third formula.
The third formula is: s ═ S1+S2。
Optionally, the power density S and the electric field strength E satisfy a fourth formula:
the fourth formula is: e ═ S2/377。
According to the formula, the electric field strength value of each communication unit can be calculated after the distance from the measuring point to the antenna, the power gain and the antenna transmitting power are obtained. The maximum allowed power of the station can also be calculated according to the above formula and electromagnetic radiation standard, and the power of each communication unit is allocated on the basis of the maximum allowed power.
The current power distribution method has the problems that the power distribution is unreasonable and the power of each communication device is difficult to be fully utilized. The application discloses a power control method, which can automatically adjust the power of each communication unit in a station, thereby more effectively utilizing the power of the communication units. Referring to fig. 2, an embodiment of a power control method according to the present application includes:
In this embodiment, the first electric field strength value is an electric field strength value measured at the measurement point when the plurality of communication units of the station configure the preset data transmission power. The plurality of communication units include communication units of different communication systems. For example, the station 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 further include a communication unit 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 an average power of transmission service data in a time period, and a duration of the time period may be set according to an actual situation, which is not limited in the present application.
When the first electric field strength value is greater than or equal to the preset electric field strength, the fact that the electric field strength value of the station is greater than the electromagnetic field radiation standard is indicated, and the fact that the data transmission power of the station is too high is also indicated, and the data transmission power of the communication unit needs to be reduced. And when the first electric field strength value is smaller than the preset electric field strength, the electric field strength value of the station is smaller than the electromagnetic field radiation standard.
The data transmission power of the station may be an arithmetic sum of the data transmission powers of all the communication units, or the data transmission power of the station may be a weighted sum of the data transmission powers of all the communication units. The weight of the data transmission power of each communication unit may be set according to actual conditions, and the present application is not limited thereto.
The second electric field strength value is an electric field strength value measured at the measurement point to the station when the plurality of communication units of the station are configured in accordance with the reduced data transmission power.
Optionally, after the data transmission power of the plurality of 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 the plurality of communication units is reduced, the data transmission power of the station 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 station.
And step 204, outputting 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. And when the second electric field strength value is larger than the preset electric field strength value, the electric field strength of the station is over high, and 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 intensity value calculated according to the reduced data transmission power is less than or equal to the preset electric field intensity, and the command may be output.
And step 205, executing power-down operation within the target time period according to the command.
The communication unit performs a power-down operation for a target period according to the command, and performs data transmission at the reduced data transmission power. The commands are used to make the power-down operation consistent with the power-down simulation process.
In this embodiment, when the data transmission power of the station is too large, the power reduction simulation is performed on the data transmission power of the plurality of communication units in the target time period. If the electric field intensity of the station does not exceed the preset electric field intensity under the simulation condition, the data transmission can be ensured to be carried out according to the reduced data transmission power in the target time period after the configuration is carried out according to the reduced data transmission power. Therefore, the power of each communication unit can be automatically adjusted, and the electric field intensity of the station does not exceed the preset electric field intensity, so that the electromagnetic radiation intensity is ensured within a safety range.
In an alternative embodiment, the power-down simulating the data transmission power of the plurality of communication units for the target period comprises:
predicting the load of each communication unit in a target period according to the historical load of the communication unit; determining the priority of each communication unit according to the prediction result; and performing power reduction simulation on the data transmission power of each communication unit in the target time period according to the priority order from high to low.
In this embodiment, the time before the target time interval may be divided into a plurality of time intervals, and then a prediction model may be trained according to the historical load amount of each time interval, and the load amount of the target time interval may be predicted using the prediction model. The duration of each time interval is equal to the duration of the target time interval, the unit of the target time interval may be minutes and hours, and the setting may be specifically performed according to the actual situation, which is not limited in the present application. The training method can be a gradient descent algorithm, a neural network algorithm and the like.
The prediction result of each communication unit in the target period is inversely related to the priority of the communication unit, i.e. 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. The power reduction simulation is preferentially carried out on the communication units with low load capacity, so that the communication units with high load capacity can use more power, the power of the communication units is distributed according to the load capacity, and the power of each communication unit is fully utilized. Moreover, the method has little or no influence on the service transmission of the site, so that the user experience is not obviously influenced or even influenced.
The order of performing the power down simulation on the plurality of communication units is not limited to be from high to low, and may be from low to high or random, and the present application is not limited thereto.
In the embodiment of the present application, the power reduction simulation of the data transmission power of each communication unit in the target time period can be implemented by various methods:
the first method is carrier shutdown, and the following embodiments can be specifically referred to:
in an optional embodiment, under the condition that the communication unit is configured with a plurality of working frequency bands and each working frequency band comprises a plurality of sub-frequency bands, one working frequency band is sequentially selected from the plurality of working frequency bands to serve as a target working frequency band, and the load capacity of each sub-frequency band in the target working frequency band in a target time period is predicted according to the historical load capacity of the sub-frequency band; taking the predicted sub-frequency band with the minimum load capacity as a target sub-frequency band; transferring all the service load of the target sub-band in the target time period to other sub-bands; and when the target frequency sub-band meets the turn-off condition, carrying out simulated carrier turn-off on the target frequency sub-band in the target time period.
The sub-bands are also referred to as sub-carriers. The target frequency sub-band and the other frequency sub-bands belong to the same working frequency band. In the process of migrating the service load of the target sub-band, a load threshold may be set for each sub-band, and when the load of the sub-band is lower than the load threshold, the service load may be migrated to the sub-band. And when the load of the sub-frequency band reaches or exceeds the load threshold value, stopping migrating the service load to the sub-frequency band.
Optionally, the migration sub-bands may be set in order of load from low to high, and the migration sub-bands are sub-bands to which the traffic load is migrated. For example, an operating band includes 5 sub-bands, and the 5 sub-bands are f1, f2, f3, f4, and f 5. The load amounts of the sub-bands are respectively D1, D2, D3, D4 and D5, and D1< D2< D3< D4< D5. According to the method of the embodiment, f1 can be determined as the target sub-band, and the traffic load of f1 is migrated to other sub-bands, wherein the migration order is f2, f3, f4 and f 5. The traffic load of the previous sub-band needs to be brought to or past the load threshold before the traffic is migrated to the next sub-band. If the entire traffic load is migrated to f2 and the amount of load of f2 does not exceed the load threshold, then f1 does not migrate the traffic load to f3, f4, f 5. If the traffic load needs to be migrated to f3, the traffic load is migrated to f2 first, so that the load amount of f2 reaches or exceeds the load threshold.
In this way, the data transmission power of the communication unit can be reduced for each operating band by traffic load shifting and sub-band switching off, thereby enabling a small or no impact on the traffic transmission of the communication unit.
In another optional embodiment, before the target sub-band is turned off by the artificial carrier in the target period, the power control method further includes: carrying out simulation carrier wave shutoff on the target sub-frequency band in a target time period; acquiring a service quality index of a target working frequency band; when the service quality index of the target working frequency band meets the preset service quality requirement, determining that the target sub-frequency band meets the turn-off condition; and when the service quality index of the target working frequency band does not meet the preset service quality requirement, determining that the target frequency sub-band does not meet the turn-off condition.
The quality of service indicator may include one or more of throughput, transmission delay, and packet loss rate. When the service quality index includes throughput, transmission delay and packet loss rate, it is required to simultaneously satisfy a plurality of conditions that the throughput is greater than or equal to the preset throughput, the transmission delay is less than or equal to the preset delay or the packet loss rate is less than or equal to the preset packet loss rate, and the like, that the service quality index of the target working frequency band satisfies the preset service quality requirement is indicated, otherwise, the service quality index of the target working frequency band does not satisfy the preset service quality requirement.
In this embodiment, the sub-bands that can be turned off and the sub-bands that cannot be turned off in each communication unit can be identified through simulation, so that the service quality can be guaranteed when the power is reduced.
The second method is beam power control, which can be specifically referred to the following embodiments:
in another optional embodiment, in a case that the communication unit is configured with a plurality of beams for data transmission, one beam is sequentially selected from the plurality of beams as a target beam, and the data transmission power of the target beam in a target time period is reduced from a preset first power to a second power; acquiring a service quality index of a target beam; and 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 interval according to the second power.
Wherein 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 the application is not limited.
In this embodiment, the data transmission power of one beam can be reduced separately, thereby achieving fine-grained power control. By reducing the power of one or more beams, the electric field strength of the station can be made to meet the safety standard and the service quality of the service can be guaranteed.
For the third method to reduce the power of the power amplifier, refer to the following embodiments:
in another alternative embodiment, the average power of the power amplifier of the communication unit in the target period is reduced from a preset third power to a fourth power; acquiring service quality indexes of all working frequency bands of a communication unit; and when the service quality indexes of all the working frequency bands of the communication unit meet the preset service quality requirement, configuring the power of the power amplifier of the communication unit in the target time period according to the fourth power.
Wherein 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 the application is not limited.
In this embodiment, the power of the power amplifier of the communication unit may be reduced, so as to implement coarse-grained power control, which may enable the electric field strength of the station to meet the safety standard and may ensure the quality of service.
In addition, the power reduction simulation of the data transmission power of each communication unit in the target time period can also be performed according to two or three of the power reduction simulation methods in sequence. For example, for a 3G communications unit, the first method may be performed first and then the third method; alternatively, the third method is performed first and then the first method is performed. For a 4G communication unit or a 5G communication unit, the first method may be performed first, and then the second method may be performed; or, the first method is executed first and then the third method is executed; alternatively, the first method is performed first, then the second method is performed, and then the third method is performed.
It should be noted that the execution order of the plurality of power-down simulation methods is not limited to the above example, and may be executed in other orders, and the present application is not limited thereto.
For the process of performing the power down simulation according to the sequence of the first method, the second method, and the third method, the following is described in detail with an embodiment:
in an alternative embodiment, the power-down simulating the data transmission power of each communication unit for the target time period comprises:
under the condition that a communication unit is configured with a plurality of working frequency bands, each working frequency band comprises a plurality of sub-frequency bands, and the communication unit is configured with a plurality of beams, one working frequency band is sequentially selected from the plurality of working frequency bands to serve as a target working frequency band, and the load capacity of each sub-frequency band in the target working frequency band in a target time period is predicted according to the historical load capacity of the sub-frequency band; taking the predicted sub-frequency band with the minimum load capacity as a target sub-frequency band; transferring all service loads of the target sub-band in the target time period to other sub-bands, wherein the target sub-band and the other sub-bands belong to the same working frequency band; when the target sub-band meets the turn-off condition, carrying out simulated carrier turn-off on the target sub-band in a target time period;
sequentially selecting one beam from the plurality of beams as a target beam, and reducing the data transmission power of the target beam in a target time period from a preset first power to a second power; acquiring a service quality index of a target beam; when the service quality index of the target wave beam meets the preset service quality requirement, configuring the data transmission power of the target wave beam in the target time interval according to a second power;
reducing the average power of a power amplifier of the communication unit in a target period from a preset third power to a fourth power; acquiring service quality indexes of all working frequency bands of a communication unit; and when the service quality indexes of all the working frequency bands of the communication unit meet the preset service quality requirement, configuring the power of the power amplifier of the communication unit in the target time period according to the fourth power.
In this embodiment, for each working frequency band, after the service load of the sub-band with the lowest load capacity is migrated to another sub-band, the sub-band with the lowest load capacity is subjected to carrier turn-off simulation. And after the sub-frequency band with the lowest load capacity in part or all of the working frequency bands is switched off, performing power reduction simulation on the data transmission power of part or all of the beams, and then performing power reduction simulation on the power amplifier of the communication unit. This enables the quality of service of the communication device transmission service to be guaranteed while power is reduced.
It should be noted that, although the qos indicators of all operating bands of the communication unit satisfy the preset qos requirement, the qos of the service may be affected during the power reduction process. The influence of carrier turn-off simulation on the service quality is minimum, the influence of beam power on the service quality is reduced for the second time, and the influence of power reduction simulation on the service quality is maximum by a power amplifier of a communication unit. By implementing the above sequence, the impact of the power reduction process on the service quality can be minimized.
