The energy-saving method of the communication base station provided by the embodiment of the invention can be applied to the application scene shown in figure 1. As shown in fig. 1, the application scenario includes a 5G communication base station 11, an active antenna unit 12, a coverage area 13 of the active antenna unit 12, and a plurality of users 14. The 5G communication base station 11 adopts an active antenna unit 12 of a Multiple-Input Multiple-Output (MIMO) technology, where the active antenna unit 12 generally uses a hardware design of Multiple transmit-receive channels and Multiple oscillators, and each transmit-receive channel includes a filter, a power amplifier, an analog-to-digital conversion part, an oscillator, and other devices. As shown in fig. 2, an Active Antenna Unit (AAU) of a 5G macro base station in a 3.5GHz band, which is issued by each host equipment manufacturer, generally has 64 transmit/receive channels TRX and 192 oscillators. The active antenna unit 12 sends out 5G radio frequency signals to the plurality of users 14, and the 5G radio frequency signals are transmitted from the horizontal direction and the vertical direction in narrow beams, so that the design can enable the coverage area of each beam to be small, the signal intensity to be strong and the interference to be small, but the energy consumption of the 5G macro base station AAU is greatly increased due to the increase of the number of the transceiving channels and the oscillators.
The embodiment of the invention provides an energy-saving method for a communication base station, which aims to solve the technical problems in the prior art.
The following describes the technical solution of the present invention and how to solve the above technical problems with specific embodiments. These several specific embodiments may be combined with each other below, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 3 is a flowchart of an energy saving method of a communication base station according to an embodiment of the present invention. The embodiment of the invention provides an energy-saving method of a communication base station aiming at the technical problems in the prior art, which comprises the following specific steps:
and 301, monitoring the utilization rate of the physical resource block of the 5G cell under the condition that the 5G cell is in the idle period.
Specifically, the 5G cell may be understood as an area covered by one 5G communication base station in fig. 1, and may also be understood as a sub-area obtained by dividing the area covered by the 5G communication base station according to a certain rule. The rules of division can be referred to the description of the related contents in the prior art, and the invention is not specifically described here.
Optionally, before this step, it needs to determine whether the 5G cell is in the idle period. Specifically, the idle period of the 5G cell may be determined according to the traffic of the 5G cell and/or the number of users having data transmission with the 5G communication base station in a certain time period.
And when the 5G cell is determined to be in the idle period, starting to monitor the utilization rate of the physical resource blocks of the 5G cell.
And step 302, closing the corresponding transceiving channel according to a preset closing rule under the condition that the utilization rate of the physical resource block of the 5G cell is less than a first preset value of the utilization rate of the physical resource block.
For example, if the utilization rate of the physical resource block of the 5G cell is 10% and the first preset value of the utilization rate of the physical resource block is 20%, the corresponding transceiving channel of the active antenna unit 12 may be turned off according to a preset turning-off rule. The preset turn-off rule may be a rule for determining which of all the transceiving channels of the active antenna unit are turned off. Optionally, the preset closing rule may be to close the corresponding transceiving channels in an order from small traffic to large traffic.
The embodiment of the invention monitors the utilization rate of the physical resource block of the 5G cell when the 5G cell is in the idle time period, and closes the corresponding transceiving channel according to the preset closing rule when the utilization rate of the physical resource block of the 5G cell is smaller than the first preset value of the utilization rate of the physical resource block, thereby realizing the energy saving of the 5G communication base station.
Optionally, determining whether the 5G cell is in the idle period includes: determining the comprehensive utilization rate of the 5G cell in a plurality of time periods; and under the condition that the times that the comprehensive utilization rate of the 5G cell in a plurality of time periods is lower than the preset comprehensive utilization rate exceed the preset times, judging that the 5G cell is in the idle period. For example, in one day, the comprehensive utilization rate of the 5G cell is counted every 30 minutes, so that 48 comprehensive utilization rates of the 5G cell can be obtained, the 48 comprehensive utilization rates are sequentially compared with the preset comprehensive utilization rate, if every 1 comprehensive utilization rate is lower than the preset comprehensive utilization rate, the number of times is recorded, after the 48 comprehensive utilization rates are compared, if the accumulated number of times exceeds the preset number of times, the 5G cell is determined to be in an idle time period, and otherwise, the 5G cell is determined to be in a non-idle time period. Of course, the statistics may also be performed according to the number of days, for example, the total utilization rate of the 5G cell for N days is counted, and if the number of times that the total utilization rate in the N days is lower than the preset total utilization rate exceeds the preset number of times, it is determined that the 5G cell is in the idle period. It should be understood that the statistical period is only an example and should not be understood as a specific limitation of the present invention, and those skilled in the art can set the statistical period according to actual requirements, for example, 15 minutes, 1 hour, K days.
Optionally, determining the comprehensive utilization rate of the 5G cell in multiple time periods includes: acquiring the flow utilization rate of the 5G cell; acquiring the utilization rate of data transmission users of the 5G cell; and determining the comprehensive utilization rate of the 5G cell in a plurality of time periods according to the flow utilization rate of the 5G cell and the data transmission user utilization rate of the 5G cell. The data transmission user utilization rate = the average number of users performing data transmission with the 5G communication base station/the data transmission user capacity of the 5G cell; the data transmission user capacity of the 5G cell is understood as the maximum number of users for data transmission at the same time allowed by the communication system. The traffic utilization rate = downlink traffic of 5G cell/traffic capacity of 5G cell; the downlink traffic of the 5G cell is the traffic downloaded from the 5G cell, and the traffic capacity of the 5G cell is the limit value of the download traffic within 1 hour under 1 5G cell. The main factors affecting the flow capacity of the 5G cell include the frequency spectrum bandwidth of the 5G cell, the number of data streams, the channel efficiency and the channel overhead, and the frequency spectrum bandwidth of the cell determines the number of Physical Resource Blocks (PRBs) of the cell.
Optionally, determining the comprehensive utilization rate of the 5G cell in multiple time periods according to the traffic utilization rate of the 5G cell and the data transmission user utilization rate of the 5G cell, and calculating according to the following formula:
a 5G Cell Comprehensive Utilization Rate (CCUR) =5G Cell traffic Utilization Rate flow weight +5G Cell data transmission user Utilization Rate user number weight;
for the 5G cell utilization rate and the 5G cell data transmission user utilization rate, the descriptions of the above embodiments are referred to, and the traffic weight and the user number weight may be set according to empirical values.
Fig. 4 is a flowchart of an energy saving method of a communication base station according to another embodiment of the present invention. On the basis of the foregoing embodiment, the energy saving method for a communication base station according to the embodiment of the present invention, when closing a corresponding transceiving channel according to a preset closing rule when the utilization rate of a physical resource block of a 5G cell is less than a first preset value of the utilization rate of the physical resource block, specifically includes the following steps:
step 401, judging whether the number of the closed transceiving channels is less than the preset number of the closable transceiving channels;
specifically, when the utilization rate of the physical resource block of the 5G cell is less than the first preset value of the utilization rate of the physical resource block, it is first required to determine whether there is a closed transceiving channel in the active antenna unit, and if there is a closed transceiving channel in the active antenna unit, further determine the number of the closed transceiving channels, and determine whether the number of the closed channels is less than the preset number of channels that can be closed.
Step 402, determining the beam traffic of a plurality of unclosed transceiving channels if the number of the closed transceiving channels is less than the preset number of closable transceiving channels;
optionally, if the number of the closed transceiving channels is less than the preset number of the closable transceiving channels, determining the beam traffic of the plurality of the unclosed transceiving channels may be determining the beam traffic of a predetermined number of the unclosed transceiving channels, where the predetermined number = the preset number of the closable transceiving channels — the number of the currently closed transceiving channels.
For example, if the number of closed channels is 10 and the preset number of closable channels is 32, the beam traffic of the remaining 22 transceiving channels is determined.
Optionally, the beam traffic refers to a comprehensive service evaluation index generated by 5G terminals in a coverage area of a 5G cell with different beams. Wherein, determining the beam traffic of a plurality of transceiving channels comprises: acquiring the number of users scheduled by wave beams of a plurality of transceiving channels, the scheduling times and the scheduling duration; and determining the beam traffic of the plurality of transceiving channels according to the number of users scheduled by the beams of the plurality of transceiving channels, the scheduling times and the scheduling duration. Specifically, the beam traffic of each transceiving channel can be determined according to the following formula: idle time period beam traffic = number of users scheduled by a certain beam of a 5G cell during idle time period + number of times of scheduling + weight of number of times of scheduling + scheduling duration + weight of scheduling duration.
Step 403, determining priorities of the plurality of unclosed transceiving channels according to the beam traffic of the plurality of unclosed transceiving channels.
Optionally, the priorities of the plurality of unclosed transceiving channels may be determined according to the ascending order of the beam traffic.
And step 404, closing the corresponding transceiving channels according to the priorities of the plurality of unclosed transceiving channels until the number of the closed transceiving channels reaches a preset number of closable transceiving channels, or until all the plurality of unclosed transceiving channels are closed.
Specifically, the corresponding transceiving channels may be sequentially closed in the order from small to large of the beam traffic until the number of closed transceiving channels reaches a preset number of closable transceiving channels, or until the unclosed transceiving channels are closed.
For example, the beam traffic of the remaining 22 transceiving channels are arranged in the order from small to large, or in the order from large to small, and then the 22 transceiving channels are sequentially closed from the transceiving channel corresponding to the smallest beam traffic. For example, the transceiving channel with the beam traffic of 0 is firstly closed, and the transceiving channel with the beam traffic of more than 0 is secondly closed.
The embodiment of the invention determines the priority of the receiving and sending channel to be closed by calculating the beam service volume in the idle time period, namely the smaller the beam service volume in the idle time period is, the higher the closed priority of the corresponding receiving and sending channel is, thereby achieving the purpose of ensuring that the perception of the coverage and the rate when a user uses a 5G network is not influenced while saving energy.
Fig. 5 is a flowchart of an energy saving method of a communication base station according to another embodiment of the present invention. On the basis of the foregoing embodiment, the energy saving method for a communication base station provided in this embodiment further includes the following steps:
step 501, judging whether the utilization rate of the physical resource blocks of the 5G cell is greater than or equal to a second preset value of the utilization rate of the physical resource blocks, wherein the second preset value is greater than the first preset value.
Specifically, this step 501 is performed after the corresponding transceiving channels are sequentially closed in an order from small to large according to the beam traffic until the number of the closed transceiving channels reaches a preset number of closable channels, or when the physical resource block utilization of the 5G cell is greater than or equal to a first preset value of the physical resource block utilization.
And 502, opening all closed transceiving channels under the condition that the utilization rate of the physical resource blocks of the 5G cell is greater than or equal to a second preset value of the utilization rate of the physical resource blocks.
