s202, acquiring user state data of the network side equipment in a history period, wherein the user state data comprises: status data of one or more user devices within a coverage area of the network side device.

S204, predicting the user state data of the network side equipment in the target time or the target time according to the user state data of the network side equipment in the history time, wherein the target time is a time after the history time, and the target time is a time period after the history time.
It should be noted that, in the implementation of S204, a user state data prediction model may be trained by machine learning to predict, according to user state data in a history period of the network side device, user state data of the network side device at a certain time (i.e., a target time) or in a certain period (i.e., a target period) in the future.
In one embodiment, S206 may be implemented by the following steps: user state data of the network side equipment in the history period are input into a pre-trained long-short-period memory LSTM model, and user state data of the network side equipment in the target time or the target period is output.
S206, generating an energy-saving control strategy of the network side equipment at the target moment or in the target period according to the user state data of the network side equipment at the target moment or in the target period.
It should be noted that, the energy-saving control policy in the embodiment of the present disclosure refers to a policy for controlling the network side device to work in an energy-saving manner, and may be, but not limited to, a sleep control policy for controlling whether the network side device sleeps. In some embodiments, a spectrum resource allocation policy for the network side device may also be generated.
S208, executing the energy-saving control strategy of the network side equipment at the target moment or in the target period.
In the implementation, the corresponding energy-saving control strategy can be executed at the target moment or in the target period so as to control the network side equipment to provide the network service for the user equipment in an energy-saving mode.
In some embodiments, the method for controlling energy saving of a network side device provided in the embodiments of the present disclosure may further include the following steps: collecting user state data of network side equipment; user state data of the network side device is stored.
In some embodiments, the method for controlling energy saving of a network side device provided in the embodiments of the present disclosure may further include the following steps: acquiring execution result data of an energy-saving control strategy; and storing execution result data of the energy-saving control strategy.
In order to prevent frequent adjustment of the energy-saving control policy of the network side device, the energy-saving control method of the network side device provided in the embodiments of the present disclosure may further include the following steps: according to the user state data of the network side equipment at the target moment or in the target period, determining the quantity ratio of the user equipment with changed state data in the network side equipment; if the number of the user equipment is not larger than the preset threshold, the energy-saving control strategy of the network side equipment in the target time or the target time period is not executed.
In the embodiment of the disclosure, the mobile situation of the user equipment is perceived and predicted, and whether the base station dormancy and the user spectrum resource allocation strategy are adjusted is determined according to the number of the users with the mobile situation, so that the challenges of frequent adjustment of the energy-saving strategy to the user SLA and the computational complexity can be reduced.
In some embodiments, the energy saving control strategy in embodiments of the present disclosure may include: and the dormancy control strategy is used for controlling the dormancy state of the network side equipment. In the implementation, a sleep control policy for controlling whether the network side device sleeps may be generated according to user state data of the network side device at a target time or in a target time period. For example, if it is predicted that a certain network side device does not have user traffic for a certain time period in the future, the network side device may be controlled to be in a dormant state for the time period; if it is predicted that a certain network side device in the dormant state may have relatively large user traffic in a certain time period in the future, the network side device may be controlled to resume from the dormant state to the normal state before the time period.
Further, in some embodiments, the energy saving control strategy in embodiments of the present disclosure may further include: and the spectrum resource allocation strategy is used for allocating spectrum resources used when the network side equipment communicates with each user equipment. The spectrum resources used by the communication between the different network side devices and the user device may be different, so that after predicting the user state data of each network side device at the target time or within the target time period, the sleep state of the network side device can be controlled, and the communication of the user device can be satisfied as much as possible under the condition of smaller energy consumption by distributing the spectrum resources of the network side device. For example, after a certain base station is controlled to be in a sleep state, other base stations adjacent to the base station can be used to provide network services for user equipment under the base station.
In some embodiments, a first antenna and a second antenna are arranged on the network side equipment and the user equipment; the first antenna communicates with each user device using a first spectral resource and the second antenna communicates with each user device using a second spectral resource, the first spectral resource having a frequency greater than the frequency of the second spectral resource. The energy-saving control method of the network side equipment provided in the embodiment of the disclosure may further include the following steps: and under the condition that the first network side equipment is in a dormant state, controlling the second network side equipment to communicate with each user equipment within the coverage range of the first network side equipment by using a second antenna, wherein the second network side equipment is network side equipment within a preset distance range with the first network side equipment.
The coverage area of the base station is small because the transmission distance of the high-frequency signal is short; the low-frequency signal transmission distance is long, and the coverage area of the base station is large, so that the coverage area of the low-frequency signal of the second network side equipment within the preset distance range with the first network side equipment can be covered to the user equipment under the first network side equipment under the condition that the first network side equipment is in a dormant state, and the second network side equipment can be controlled to communicate with each user equipment within the coverage area of the first network side equipment by using the low-frequency second antenna. In the embodiment of the disclosure, the high-frequency signal coverage problem and the small base station energy consumption problem are comprehensively considered, and the high-low frequency spectrum allocation, the user flow prediction and the small base station dormancy are combined, so that the communication capacity of the 5G cellular system can be improved while the energy consumption of the 5G cellular system is reduced.
In some embodiments, generating the energy-saving control policy of the network side device at the target time or within the target period according to the user state data of the network side device at the target time or within the target period includes: determining a spectrum resource allocation strategy of network side equipment by adopting a Hungary algorithm; and determining a dormancy control strategy of the network side equipment by adopting a genetic algorithm.
Because the channel capacities of the user equipments using different spectrum resources are different, in some embodiments, the method for controlling energy saving of the network side equipment provided in the embodiments of the present disclosure may further include the following steps: acquiring spectrum resources used by each user equipment; determining the channel capacity of each user equipment according to the spectrum resources used by each user equipment; and under the condition that the channel capacity of each user equipment meets the minimum channel capacity, determining a spectrum resource allocation strategy and a dormancy control strategy adopted by each network side equipment when the energy consumption is minimum.
In the implementation, channels with different frequency spectrums utilize a Friis channel fading formula, or according to the inverse proportion of the channel fading and the frequency of the channel, the channel capacity of a specific user equipment when using a certain frequency spectrum is determined by combining with a shannon formula, and the channel capacity and the distance between transceiver equipment are inversely related;
Taking a network side device as an example of a base station, fig. 3 is a schematic diagram illustrating a specific implementation system frame of an energy-saving control method of the network side device in an embodiment of the disclosure, and as shown in fig. 3, the energy-saving control system of the network side device provided in the embodiment of the disclosure may specifically include: the system comprises a sensing module, a prediction module, a decision module, an execution result feedback module, a data storage module and a timing module.
In some embodiments, the sensing module includes a user distribution sensing unit and a user idle state unit in the vicinity of the base station; the user distribution sensing unit near the base station senses the distribution condition of each moment around the base station and records the distribution condition in the user activity data storage module near the base station of the data storage module; the user idle state unit stores the perceived real-time idle state of the user to the user state data unit of the data storage module.
In some embodiments, the prediction module comprises a user distribution prediction unit and a user mobility prediction unit; the prediction module is used for predicting the user quantity entering the area near each base station in a certain time period or at a certain moment with the aid of the timing module according to the historical data of the user distribution condition of the data storage module and at a preset time interval (such as T0); and the mobility prediction unit makes a strategy for dormancy or distribution of the base station and the frequency spectrum before the time T1 according to the predicted user flow demand at the time T1, and gives the strategy to the execution module for execution at the time T1.
In some embodiments, the decision module comprises a spectrum allocation unit and a base station sleep decision unit; the decision module in the embodiment of the disclosure can allocate spectrum resources by utilizing a resource allocation algorithm such as Hungary; decision-making algorithms such as genetic algorithm can be used to make decisions on whether the base station is dormant or not. And in the decision process, the decision module obtains a spectrum resource allocation strategy and a base station dormancy control strategy with minimum energy consumption under the condition of ensuring that each user equipment meets the minimum channel capacity according to the two-dimensional comprehensive decision of spectrum allocation and base station dormancy. Alternatively, the minimum channel capacity of each user equipment may be the same, or the minimum channel capacity may be determined according to the package condition of each user.
