Fig. 4 is a flowchart illustrating an energy saving control method according to an embodiment of the present application. As shown in fig. 4, the energy saving control method includes the following S401 to S405.
S401, the wireless access network equipment predicts index information of the target cell in a first time period.
Wherein, the index information is used for representing the data transmission performance of the target cell.
Specifically, when predicting the index information of the target cell in the first time period, the radio access network device may first obtain the index information of the target cell in a certain historical time period. The radio access network device may then predict the indicator information of the target cell for the first time period based on the indicator information of the target cell for the certain historical time period and the prediction algorithm.
Optionally, the index information includes: at least one of a Physical Resource Block (PRB) utilization rate, a Control Channel Element (CCE) utilization rate, a Radio Resource Control (RRC) user connection number, a radio resource utilization rate, or a traffic. The PRB utilization rate may be divided into an upper PRB utilization rate, a lower PRB utilization rate, and a downlink PRB utilization rate.
Illustratively, the preset day is 6/29/2020. The wireless access network equipment firstly acquires index information of 8-20 point time periods each day in ten days from 10 days 6 month in 2020 to 20 days 6 month in 2020. Then, the radio access network device predicts index information of the target cell in a time period of 8 o 'clock to 20 o' clock in 6/month and 30/month in 2020 according to an Artificial Intelligence (AI) algorithm, such as a long short-term memory network (LSTM) algorithm, a time series prediction (prophet) algorithm, and the like.
For example, the index information of the radio access network device for predicting the target cell in the time period of 8 o 'clock to 20 o' clock at 30 days 6 and 30 months 2020 by using the AI algorithm includes: at least one of an uplink PRB utilization ratio UP, a downlink PRB utilization ratio DP, a CCE utilization ratio C, a radio resource utilization ratio W, RRC user connection number R or traffic B. To facilitate the storage of the index information, the radio access network device may divide a period of time from 8 o 'clock to 20 o' clock of 30 days 6 and 2020 into n intervals. In this case, the uplink PRB utilization UP includes: up1, up2, upn. The downlink PRB utilization DP includes: dp1, dp 2.., dpn. CCE utilization C comprises: c1, c 2. The radio resource utilization rate W includes: w1, w 2. The RRC user connection number R includes: r1, r 2. The flow rate B comprises: b1, b 2. Wherein n is an integer greater than 1.
S402, the wireless access network equipment judges whether index information of the target cell in the first time period meets a preset condition.
After predicting the index information of the target cell in the first time period, the wireless access network equipment judges whether the index information of the target cell in the first time period meets the preset condition for energy-saving control. If the index information of the first time period meets the preset condition, the wireless access network equipment executes S403; if the index information of the first time period does not satisfy the preset condition, the radio access network device executes S405.
Specifically, the preset condition may be that each index in the index information of the target cell in the first time period is smaller than a threshold corresponding to each index, or that a sum of each index in the index information of the target cell in the first time period is smaller than a preset threshold, or that m indexes in the index information of the target cell in the first time period are smaller than thresholds corresponding to m indexes, which is not limited in this embodiment of the present application. Wherein m is an integer greater than 1.
Illustratively, the threshold vector of each index in the index information of the preset target cell is Q. When the radio access network equipment predicts that each index in the index information of the target cell in the first time period is smaller than the threshold value Q, determining that the index information of the target cell in the first time period meets a preset condition, and executing S403 by the radio access network equipment; otherwise, S405 is executed.
Optionally, the radio access network device may further determine that each index in the index information of the target cell is smaller than the number K of segments of the continuous time period of the threshold Q. When K is greater than K1, determining that the index information of the target cell in the first time period meets the preset condition, and executing S403 by the wireless access network equipment; otherwise, S405 is executed. Wherein k1 is a positive integer greater than 0 and less than n.
S403, the wireless access network equipment determines the energy-saving control priority of the target cell.
And when the index information of the target cell in the first time period is determined to meet the preset condition, the target cell can execute the energy-saving control strategy. In order to avoid the problem of low working efficiency caused by the fact that the wireless access network equipment executes the energy-saving control strategy on a plurality of cells at the same time, the wireless access network equipment determines the energy-saving control priority of a target cell.
Optionally, when the radio access network device determines the energy-saving control priority of the target cell, the network information of the target cell may be first used, and then the energy-saving control priority may be determined according to the network information and a preset algorithm. Wherein the network information includes: at least one of a network scene, a network coverage type, a network frequency band, a frequency band hierarchy corresponding to the network frequency band, a network system or an area type;
specifically, the network scenario includes: a member (VIP) area, a traffic hub, a rural area, an office area, a business area, a school, a residential area, or a scenic area. The network coverage types include: indoors or outdoors. The network frequency band comprises: at least one of a very low frequency (3 kilohertz (kHz) -30kHz), a low frequency (30kHz-300kHz), an intermediate frequency (300kHz-3000kHz), a high frequency (3 megahertz (MHz) 3-30 MHz), a very high frequency (30MHz-300MHz), an ultra high frequency (300MHz-3000MHz), an ultra high frequency (3 gigahertz (GHz) -30GHz), an extremely high frequency (30GHz-300GHz), or a at least high frequency (300GHz-3000 GHz). The frequency band hierarchy corresponding to the network frequency band comprises: at least one of an overlay layer, a capacity layer, and a hot spot layer. The network system comprises: at least one of a second generation mobile communication technology (2G), a third generation mobile communication technology (3G), a fourth generation mobile communication technology (4G), or a fifth generation mobile communication technology (5G). The region types include: a branded area and a non-branded area.
The radio access network device may add a weight value to each parameter in the network information of the target cell, and determine the energy-saving control priority of the target cell according to a preset algorithm.
Specifically, the wireless access network equipment adds a weight a to a network scene A of a target cell; adding weight D to the network coverage type D; adding a weight E to a network frequency band E; adding a weight F to a frequency band level F corresponding to a network frequency band, and adding a weight G to a network system G; a weight H is added for region type H. In this case, the energy-saving control priority J of the target cell satisfies the following formula:
J＝A*a+D*d+E*e+F*f+G*g+H*h。
s404, the wireless access network equipment executes an energy-saving control strategy on the target cell according to the energy-saving control priority.
Wherein the energy-saving control strategy is used for reducing the power consumption of the target cell.
After determining the energy-saving control priority of the target cell, the radio access network device executes an energy-saving control strategy for the target cell according to the energy-saving control priority. When the radio access network device executes the energy-saving control policy on the target cell, the specific method for executing the energy-saving control policy may refer to an existing method for executing the energy-saving control policy on the target cell by the radio access network device, which is not described herein again.
It should be appreciated that when the radio access network device covers multiple cells, the radio access network device determines energy saving control priorities corresponding to the multiple cells. And then sequencing the energy-saving control priorities corresponding to the plurality of cells according to the size sequence, and preferentially executing the energy-saving control strategy on the cell with the higher energy-saving control priority, thereby avoiding the problem of low working efficiency caused by the fact that the wireless access network equipment executes the energy-saving control strategy on the plurality of cells at the same time.
Optionally, before the energy-saving control policy is executed on the target cell according to the energy-saving control priority, the radio access network device determines whether to execute the energy-saving control policy according to the index information of the predicted target cell in the first time period. In order to verify the accuracy of the prediction, the radio access network device may further obtain the index information of the target cell in the second time period, and determine whether the index information of the target cell in the second time period meets a preset condition. If the index information of the second time period meets the preset condition, executing an energy-saving control strategy on the target cell according to the energy-saving control priority; if the index information of the second time period does not satisfy the preset condition, S405 is executed.
Wherein the second time period is a time period before the first time period. It should be understood that the second time period may be any time period before the first time period, and the embodiment of the present application does not limit this. In order to improve the accuracy of the verification prediction, the embodiment of the present application takes the second time period as a first time period before the first time period as an example.
Illustratively, the preset day is 6/29/2020. The wireless access network equipment firstly acquires index information of 8-20 point time periods each day in ten days from 10 days 6 month in 2020 to 20 days 6 month in 2020. Then, the wireless access network equipment predicts that the index information of the target cell in the time period of 8 o 'clock-20 o' clock of 30 days 6 and 30 months in 2020 meets the preset condition according to the AI algorithm, and the wireless access network equipment determines that the energy-saving control priority of the target cell is the highest. Before executing the energy-saving control strategy on the target cell, the radio access network device may further obtain the index information of the target cell in the time period of 8 o 'clock-20 o' clock 6/28/2020, and determine whether the index information of the target cell in the time period of 8 o 'clock-20 o' clock 6/28/2020 meets the preset condition. If the index information of the time period of 8-20 points on 28 days 6 and 28 months in 2020 meets the preset condition, executing an energy-saving control strategy on the target cell according to the energy-saving control priority; if the index information of the time period of 8 o 'clock to 20 o' clock on 28 th day 6/month 2020 does not satisfy the preset condition, S405 is executed.
S405, the wireless access network equipment does not execute the energy-saving control strategy on the target cell.
Specifically, if the index information of the first time period does not satisfy the preset condition, it is indicated that the target cell does not comply with the energy-saving control execution strategy. In this case, the radio access network device does not execute the energy saving control strategy for the target cell in order to guarantee the service quality of the target cell.
Optionally, the index information of the first time period meets the preset condition, but the index information of the second time period does not meet the preset condition, which indicates that the prediction of the radio access network device is inaccurate. In this case, the radio access network device does not execute the energy saving control strategy for the target cell in order to guarantee the service quality of the target cell.
The embodiment of the application provides an energy-saving control method, which comprises the following steps: the wireless access network equipment firstly predicts index information of the target cell in a first time period, wherein the index information is used for expressing the data transmission performance of the target cell. And if the index information in the first time period meets the preset condition, the wireless access network equipment determines the energy-saving control priority of the target cell and executes an energy-saving control strategy on the target cell according to the energy-saving control priority. The energy saving control strategy is used to reduce power consumption to the target cell.
As can be seen from the above, the radio access network device determines whether to execute the energy saving control strategy on the target cell according to the predicted index information of the target cell in the first time period. Therefore, the wireless access network equipment can only execute the energy-saving control strategy on the cell of which the index information meets the preset condition, and the service quality of the cell covered by the wireless access network equipment is ensured.
Secondly, when the index information of the target cell meets the preset condition, the wireless access network equipment determines the energy-saving control priority of the target cell and executes an energy-saving control strategy on the target cell according to the energy-saving control priority. In this case, the radio access network device may sequentially execute the energy-saving control policy on the covered cells according to the energy-saving control priority, thereby avoiding a problem of low working efficiency caused by the radio access network device executing the energy-saving control policy on a plurality of cells at the same time.
In summary, the energy-saving control method provided by the application not only ensures the working efficiency of the radio access network device, but also ensures the service quality of the coverage cell of the radio access network device, and solves the technical problem that the power consumption of the radio access network device cannot be reasonably reduced by the existing energy-saving control method.
