Description
Technical Field
The present disclosure relates to a base station energy saving device, a base station energy saving method, a base station energy saving system, a base station management device, and a storage medium. More particularly, the present disclosure relates to techniques for implementing base station energy conservation and consumption reduction.
Background
Along with the influence of urbanization development on the environment, energy conservation and emission reduction are more and more concerned by people, and various energy conservation works are also actively carried out by various large communication operators so as to reduce the influence on the environment. In recent years, with the rapid growth of mobile subscribers and the introduction of unlimited flow packages, the number of base stations of communication carriers is also rapidly increasing, and accordingly, the electric charge of the base stations accounts for a larger proportion, and telecommunication carriers and equipment providers pay more attention to the problem of reducing the power consumption of base station equipment.
However, the energy saving of the base station is a system engineering, and the factors such as the wireless environment, the air-conditioning environment, the building structure and the like need to be comprehensively considered. For this reason, equipment providers have put forward energy-saving schemes for their own Base station equipment, and issue an energy-saving policy and a LICENSE to a BBU (Building Base band unit) of the Base station, thereby achieving energy saving and emission reduction through radio frequency shutdown, channel shutdown, symbol shutdown, and the like. In addition, as an energy-saving strategy, the power supply of the base station is controlled to be switched on and off at night by adding the internet of things equipment in the base station equipment room, so that the purposes of energy conservation and consumption reduction are achieved.
Disclosure of Invention
However, in the energy saving scheme introduced by the base station equipment provider, the telecom operator needs to purchase LICENSE for each base station and even each cell. In addition, although the scheme can also be applied to a 5G mobile network, the LICENSE needs to be purchased again for the 5G device, thereby increasing the networking cost. In addition, in this scheme, an energy saving control strategy is set in each base station, thereby causing complication of control of the wireless part of the base station.
In addition, in the energy saving scheme implemented by the internet of things hard shutdown, the telecom operator is also required to purchase the internet of things equipment for each base station, and hardware installation is also required. Furthermore, in the implementation of this solution, the power line of the 2.1G frequency band power supply needs to be modified, thereby further increasing the networking cost of each telecommunications carrier. In addition, the internet of things hard turn-off scheme can only realize radio frequency turn-off or cell deactivation but cannot realize channel turn-off and symbol turn-off, and the application has limitations. In addition, the hard turn-off scheme of the internet of things also has the problems of fixed energy-saving time and poor flexibility.
An object of the present disclosure is to provide a base station energy saving device, a base station energy saving method, a base station energy saving system, a base station management device, and a storage medium, which can achieve base station energy saving and emission reduction at a lower cost.

Detailed Description
Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. It is to be noted that in the present specification and the drawings, structural elements having substantially the same function and structure are denoted by the same reference numerals, and repeated explanation of these structural elements is omitted.
First, in order to facilitate understanding of the technical solutions of the present disclosure, some large data platforms and northbound interfaces applicable to the embodiments of the present disclosure are briefly described below.
In recent years, the concept of "big data" has been more and more frequent in people's productive life. As the name suggests, a key feature of large data is the enormous size of the data volume. In addition, the application fields of big data are widely distributed, for example, financial big data, traffic big data, educational big data, and the like. The large data platform is generated for meeting various requirements of enterprises on large data, is not only a simple storage technology aiming at the large data, but also a series of technologies of extraction, integration, management, analysis and interpretation related to the large data, and is a brand new technical architecture for mining values from the large data through acquisition, storage and analysis of the large data.
In the network Management system, an interface between the element Management system EMS (element Management system) and the element ne (network element) managed by the element Management system EMS (element Management system) is generally called a "southbound interface", whereas an interface between the element Management system EMS and the network Management system nms (network Management system) is generally called a northbound interface. It can be seen that the south-bound interface and the north-bound interface are relative concepts, and the interface below the network element management layer is generally called the south-bound interface, and the interface above the network element management layer is generally called the north-bound interface. The network management layer can obtain the related information of the network element managed by the network element management layer from the network element management layer through the northbound interface, such as information of alarm data, configuration data, performance data, the number of real-time users and the like, and can issue related operation instructions.
Hereinafter, an exemplary embodiment of a base station power saving technique according to an embodiment of the present disclosure will be described with reference to fig. 1 and 2.
Fig. 1 schematically shows a schematic diagram of an example of the configuration of a base station energy saving system 100 of an embodiment of the present disclosure. As shown in the schematic diagram of fig. 1, the base station energy saving system 100 may include: a base station energy saving device 101, one or more base station management devices (illustrated as a base station management device 103 and a base station management device 105 in fig. 1), and one or more base stations (illustrated as base stations 102-1, 102-2, 102-3 … and base stations 104-1, 104-2, 104-3 … in fig. 1, hereinafter simply referred to as base stations).
In addition, in the present disclosure, the base station energy saving apparatus 101 implements energy saving control of the base station based on, for example, a large data platform. Specifically, the base station energy saving device 101 acquires the number of real-time users of one or more cells (not shown) corresponding to the base stations managed by the base station management devices 103 and 105 and the configuration data of the cell via the northbound interface, and generates a control command for turning on or off each cell based on a predetermined rule according to the number of real-time users of the cell and the configuration data. Furthermore, a northbound MML (Man-Machine Language) command line interface, which is one of northbound interfaces provided by the base station management device, is called, the generated control command for turning on or off each cell is transmitted to the corresponding base station management device 103, 105, and the execution result transmitted by the base station management device 103, 105 is received and recorded in the large data platform database. Details of the base station energy saving apparatus 101 will be described later.
It should be understood that the manner described above based on the big data platform is only one manner for the present disclosure to implement the energy saving control of the base station, and the base station energy saving device 101 of the present disclosure may also implement the energy saving control of the base station not based on the big data platform but based on a general server.
The base station management devices 103 and 105 may be, for example, professional-level network management servers set by respective base station device providers for respective base station devices. The base station management devices 103, 105 send the number of real-time users of one or more cells corresponding to the base station managed by the base station management device 101 and the configuration data of the cell to the base station energy saving device 101 at predetermined time intervals or in response to an inquiry request from the base station energy saving device 101. In addition, the base station management devices 103 and 105 receive the control command for turning on or off one or more cells sent by the base station energy saving device 101, and send the control command to the base station corresponding to the target one or more cells, so that the base station, for example, the baseband processing unit BBU, executes the control for turning on or off one or more cells. In addition, the base station management apparatuses 103, 105 receive the execution result of the control command for turning on or off one or more cells from the base station, and transmit the execution result to the base station energy saving apparatus 101 via the northbound MML command line interface. Details of the base station management apparatuses 103 and 105 will be described later.
Fig. 2 schematically shows an illustrative signaling diagram of the power saving process of the base station power saving system of an embodiment of the present disclosure. In the description of fig. 2, an LTE cell in a 4G network is taken as an example, but the base station energy saving technique of the present disclosure is not limited to the 4G network, and can be applied to any mobile network such as a 2G/3G/4G/5G network.
It should be understood that before starting the energy saving process shown in fig. 2, the base station management apparatuses 103 and 105 complete parameter configuration for each base station, each base station has established communication connection with the base station management apparatuses 103 and 105, and the base station management apparatuses 103 and 105 store configuration data of one or more cells corresponding to each base station. The base station management apparatuses 103 and 105 can grasp the number of real-time users in one or more cells corresponding to each base station in real time by, for example, call statistics, paging statistics, IP traffic statistics, radio channel quality statistics, CPU load statistics, and the like from the cell corresponding to each base station.
In the signaling diagram of fig. 2, the base station energy saving device 101 queries the base station management devices 103 and 105 via the northbound interface about the number of real-time users of one or more cells corresponding to the base station that they respectively manage and about the configuration data of the cell (S1001). The inquiry processing in step S1001 may be performed, for example, every predetermined time. The predetermined time may be appropriately set as needed, and may be set to 5 minutes, 10 minutes, 15 minutes, or the like, for example. After that, the base station management apparatuses 103, 105 transmit the number of real-time users of the corresponding one or more cells and the configuration data of the cell to the base station energy saving apparatus 101 in response to the request from the base station energy saving apparatus 101 (S1002). In addition, in some embodiments, the process of S1001 may also be omitted, and the base station management apparatuses 103 and 105 may automatically transmit, to the base station energy saving apparatus 101, the number of real-time users of one or more cells corresponding to the base stations managed by each and the configuration data of the cell at predetermined time intervals.
After receiving the number of real-time users of one or more cells and the configuration data of the cell transmitted from the base station management apparatus 103, 105, the base station energy saving apparatus 101 generates a control command for turning on or off the one or more cells based on a predetermined rule based on the number of real-time users of the one or more cells, the history command execution situation, the start and end time of energy saving control, and the like, and transmits the generated control command to the base station management apparatus 103, 105 via the northbound MML command line interface (S1003). The control commands may be periodically turned on or off, or may be dynamically turned on or off, and may be appropriately set as needed in specific implementation.
The base station management apparatus 103, 105 that receives the control command for turning on or off one or more cells from the base station energy saving apparatus 101 transmits the control command to the base station corresponding to the one or more cells (S1004). In the case of receiving the control command to turn on or off the one or more cells, the base station BBU executes the corresponding processing and feeds back the energy saving processing execution result to the base station management apparatus 103, 105 (S1005). Here, the process of turning on or off one or more cells by the base station BBU may be implemented by using a well-known procedure, and a description thereof is omitted here.
Next, the base station management apparatus 103, 105 transmits the received processing execution result to the base station energy saving apparatus 101 via the northbound MML command line interface (S1006), and the base station energy saving apparatus 101 stores the received command execution result as command execution history data.
According to the base station energy-saving system disclosed by the invention, the energy-saving control of the base station is realized based on the big data platform and the northbound interface, the LECENSE of a base station equipment provider or the hard turn-off equipment of the Internet of things does not need to be purchased for each base station or cell, the energy-saving control of the base station can be realized only by one-time software development investment, and the small cost and the large benefit are really realized.
In addition, according to the base station energy saving system of the present disclosure, the energy saving policy setting is set not in a plurality of base station management devices set by each device provider for its own device, nor in a large number of base stations, but in a base station energy saving device implemented based on a large data platform, and it is possible to flexibly adjust setting as a cell or a base station for energy saving control according to the number of real-time users of a network.
In addition, the base station energy-saving strategy realized based on the big data platform is suitable for mobile networks such as 2G/3G/4G/5G and has strong expansibility.
Fig. 3 schematically shows an illustrative block configuration diagram of a base station energy saving device of an embodiment of the present disclosure.
In some embodiments, base station energy saving device 2000 may include processing circuitry 2010. The processing circuit 2010 of the base station energy saving device 2000 provides various functions of the base station energy saving device 2000. In some embodiments, the processing circuitry 2010 of the base station energy saving device 2000 may be configured to perform a base station energy saving method in the base station energy saving device 2000.
In some embodiments, processing circuitry 2010 may include: a user number and configuration data acquisition unit 2020, a decision processing unit 2030, and a command execution unit 2040.

In some embodiments, the base station energy saving device 2000 may further include a memory (not shown). The memory of the base station energy saving device 2000 may store information generated by the processing circuit 2010 as well as programs and data for operation of the base station energy saving device 2000. The memory may be volatile memory and/or non-volatile memory. For example, memory may include, but is not limited to, Random Access Memory (RAM), Dynamic Random Access Memory (DRAM), Static Random Access Memory (SRAM), Read Only Memory (ROM), and flash memory.
In addition, the base station power saving apparatus 2000 may be implemented at a chip level, or may also be implemented at a device level by including other external components.
It should be understood that the user number and configuration data obtaining unit 2020, the decision processing unit 2030 and the command executing module 2040 are only logic modules divided according to specific functions implemented by them, and are not used to limit the specific implementation manner. In actual implementation, the above units may be implemented as separate physical entities, or may also be implemented by a single entity (e.g., a processor (CPU or DSP, etc.), an integrated circuit, etc.).
In some embodiments, for example, in order to ensure normal turning on and off of a cell, and prevent possible influences caused by unexpected events such as server collapse, unexpected termination of a database and a program, regarding a large data platform serving as a basis of the base station energy saving device 2000, in addition to setting an active server, a standby server may be set up to recover the active server when the active server is unavailable. The standby program running on the standby server does not use a database, only when the abnormality of the main program is detected, the recovery program is started immediately, a recovery command is issued to the professional network management system, and related personnel are notified through the short message platform. Here, the switching control of the master/slave network manager may use a known technique, and a detailed description thereof is omitted here.
In some embodiments, in order to visually display the working condition and the overall energy saving effect of each cell, the base station energy saving device 2000 may display the current energy saving operation condition of each cell through, for example, a web page (for example, through the page display interface shown in fig. 1), a short message (for example, through the short message interface shown in fig. 1), and the like. In addition, in some embodiments, the base station energy saving device 2000 may also dynamically add or delete the target cell to be subjected to energy saving control through a configuration interface (e.g., the configuration interface shown in fig. 1). Further, in some embodiments, the base station energy saving device 2000 may also suspend energy saving control of the cell performing the energy saving control, or adjust energy saving parameters of the cell.
In addition, in some embodiments, the base station energy saving apparatus 2000 may also set a start time and an end time to be subjected to energy saving control for one or more cells, and generate a control command for turning off the one or more cells only during the set period of energy saving control.
Fig. 4 schematically shows an illustrative flow chart of a base station energy saving method performed in the base station energy saving device 2000 of an embodiment of the present disclosure.
In step S2001, the user number and configuration data acquisition unit 2020 acquires the number of real-time users of a cell and configuration data of the cell from the base station management apparatus 3000.
In some embodiments, the user number and configuration data acquisition unit 2020 may transmit a request for collecting the number of real-time users of one or more cells and the configuration data of the cell to the base station management apparatus 3000, and then the user number and configuration data acquisition unit 2020 receives the number of real-time users of one or more cells and the configuration data of the cell transmitted by the base station management apparatus 3000. In other embodiments, the base station management device 3000 may also automatically report the number of real-time users of the corresponding one or more cells and the configuration data of the corresponding cell to the base station energy saving device 2000 directly.
In the above embodiment, the user number and configuration data acquisition unit 2020 may transmit the acquisition request every predetermined time. In addition, the base station management apparatus 3000 may also automatically report to the base station energy saving apparatus 2000 every predetermined time.
In addition, in a specific implementation, the predetermined time may be set as appropriate according to a requirement, for example, the user number and the configuration data acquisition unit 2020 may acquire the real-time user number of the LTE cell from the northbound interface performance data PM of the base station management apparatus 3000 by taking 15 minutes as a granularity and delaying for about 40 minutes. Alternatively, for example, it is also possible to provide: in the centralized task management of the base station management device 3000, for example, a periodic task with a granularity of 10 minutes or 5 minutes is established, and a command such as DSP cell count (i.e., query of cell terminal access statistics information) is executed on all cells corresponding to the base station management device 3000, so as to collect the real-time RRC connection user number situation of each cell in real time. Further, the user number of the base station energy saving device 2000 and the configuration data acquisition unit 2020 acquire the real-time RRC connection user number of each cell in real time, for example, via the northbound interface of the base station management device 3000. In addition, by using the same technology, the user number and configuration data acquisition unit 2020 can also periodically acquire the basic configuration data CM of each base station BBU and each cell from the base station management device 3000 through the northbound interface, and when the network performs cutover, the basic configuration data CM will be periodically updated, and the configuration data required when the base station energy-saving device 2000 generates the energy-saving command will be updated in time.
Returning to fig. 4, the following processing of step S2003 is continuously described.
In this step S2003, the decision processing unit 2030 generates a control command for turning off at least a part of functions of a cell based on real-time user data and configuration data of the cell, so as to perform energy saving control on the cell.
The configuration data of the cell may include, for example, a cell type, a cell global identification number, a base station identifier, frequency band information, channel information, and the like.
In some embodiments, the control command for switching off a cell is generated when the number of real time users of the cell is less than a predetermined threshold. The predetermined threshold value may be set as appropriate based on actual experience, for example.
In some embodiments, the decision processing unit 2030 generates corresponding activation and deactivation control commands for the target LTE cell according to a preset logic rule in combination with the number of real-time users of the target LTE cell, command execution history data, and preconfigured start and end times for performing energy saving control received in step S2001.
In some embodiments, in a case where it is determined that a cell is a dual-band co-coverage cell according to the configuration data, the control command for turning off the cell includes a command for turning off a radio frequency module of any one of the dual bands. For example, when it is determined that the target LTE cell is the 1.8G band and the 2.1G band co-coverage cell according to the configuration data, and when the total number of RRC connection users in the cell is smaller than a predetermined threshold, for example, smaller than 5, the decision processing unit 2030 decides that the cell in the 2.1G band can be deactivated, that is, the radio frequency module in the 2.1G band can be turned off. Of course, when the total number of RRC connected users in a cell is less than 5, the decision processing unit 2030 may also determine that a cell in the 1.8G frequency band can be deactivated. On the other hand, when the total number of RRC connected users in the target LTE cell is greater than the predetermined threshold, for example, greater than 20, the decision processing unit 2030 decides that the cell in the 1.8G frequency band or the cell in the 2.1G frequency band can be activated, that is, the radio frequency module in the 1.8G frequency band or the radio frequency module in the 2.1G frequency band can be turned on.
In some embodiments, in the case that it is determined from the configuration data that the cell is a dual channel cell, the control command for turning off the cell comprises a command for turning off a radio frequency module of any one of the dual channels. For example, in the case that the target LTE cell is determined to be a dual-channel cell according to the configuration data, when the number of RRC connected users of the dual-channel target LTE cell is 0, the decision processing unit 2030 generates a command to close one of the channels; when the number of RRC connected users in the dual-channel target LTE cell is greater than 1, the decision processing unit 2030 generates a command to open a channel.
In some embodiments, the base station energy saving device 2000 may further include a history data acquiring unit (not shown) configured to acquire a command execution result for the control command from the base station management device and store the command execution result as command execution history data of the cell.
In some embodiments, the control command may be generated further from command execution history data in addition to real-time user data, configuration data of the cell.
In some embodiments, the control command for turning off at least a part of the functions of the cell is generated only in a case where it is determined that the cell is currently in an on state according to the stored command execution history data.
In some embodiments, the control command for turning off a cell is generated only if it is determined from the stored command execution history data that the cell is currently in an on state when the number of real-time users of the cell is less than a predetermined threshold.
In some embodiments, in the case where the target LTE cell is the 1.8G band and the 2.1G band same coverage cell as described above, the decision processing unit 2030 executes history data based on the stored command, and in the case where the last action for the cell to be deactivated is a shutdown operation, ends the processing without performing any operation. In addition, when the command execution history data for the cell to be deactivated is not matched in the database, or the last action for the cell to be deactivated is not a shutdown operation, a control command for shutting down the radio frequency module of the target frequency band is generated. On the other hand, the decision processing unit 2030, based on the stored command execution history data, in the case where the last action for the cell of the frequency band to be activated is the on operation, ends the processing without performing any operation. In addition, when the command execution history data for the cell of the frequency band to be activated is not matched in the database, or the last action for the cell of the frequency band to be activated is not the on operation, a control command for turning on the radio frequency module of the target frequency band is generated.
Returning again to fig. 4, the following processing of step S2004 is continuously described.
In step S2004, the generated control command is transmitted to the base station management apparatus, so that the base station management apparatus performs energy saving control on the cell according to the control command. The command execution unit 2040 of the base station energy saving device 2000 can, for example, call a northbound MML command interface provided by the device management device 3000, and transmit the control command generated in step S2003 to the base station management device 3000. Here, it should be noted that the command execution unit 2040 does not actually perform the control command for turning on or off one or more cells in person, and the processing of the control command is actually completed at the base station.
In some embodiments, optionally, the base station energy saving method may include step S2005.
In step S2005, it is determined whether or not the process is ended in the energy saving control period of the set energy saving start time and energy saving end time, and if the process is in the energy saving control period, the process returns to step S2001.
According to the base station energy saving device 2000 of the exemplary embodiment of the present disclosure, only one software development investment based on a big data platform is required, and it is not necessary to purchase a leave or an internet of things hard-off device of a base station device provider for each base station or cell, so that energy saving control of the base station can be achieved at a lower cost. In addition, the base station energy-saving equipment disclosed by the invention can be applied to mobile networks such as 2G/3G/4G/5G and the like, and has strong expansibility.
Fig. 5 schematically shows an exemplary configuration block diagram of the base station management apparatus 3000 of the embodiment of the present disclosure.
As shown in fig. 5, the base station management apparatus 3000 of the present disclosure includes a processing circuit 3010. Among them, the processing circuit 3010 in the base station management apparatus 3000 provides various functions of the base station management apparatus 3000. In some embodiments, the processing circuit 3010 of the base station management apparatus 3000 may be configured to execute a base station power saving method to be executed in the base station management apparatus 3000.
Processing circuit 3010 may refer to various implementations of digital circuitry, analog circuitry, or mixed-signal (a combination of analog and digital) circuitry that perform functions in a computing system. The processing circuitry may include, for example, circuitry such as an Integrated Circuit (IC), an Application Specific Integrated Circuit (ASIC), portions or circuits of an individual processor core, an entire processor core, an individual processor, a programmable hardware device such as a Field Programmable Gate Array (FPGA), and/or a system including multiple processors.
In some embodiments, the processing circuit 3010 may include a user number and configuration data reporting unit 3020 and an energy saving performing unit 3030, where the user number and configuration data reporting unit 3020 is configured to perform step S3001 in the energy saving method for a base station shown in fig. 6, and the energy saving performing unit 3030 is configured to perform step S3002 and step S3003 in the energy saving method for a base station shown in fig. 6.
In some embodiments, the processing circuitry of the base station management apparatus 3000 may also include a storage unit that may also store information generated by the processing circuitry 3010, as well as programs and data for operation of the base station management apparatus 3000. The memory may be volatile memory and/or non-volatile memory. For example, memory may include, but is not limited to, Random Access Memory (RAM), Dynamic Random Access Memory (DRAM), Static Random Access Memory (SRAM), Read Only Memory (ROM), and flash memory.
In addition, the base station management apparatus 3000 may be implemented at a chip level, or may be implemented at a device level by including other external components.
It should be understood that the user number and configuration data reporting unit 3020 and the power saving performing unit 3030 are only logic modules divided according to specific functions implemented by them, and are not used to limit the specific implementation manner. In actual implementation, the above units may be implemented as separate physical entities, or may also be implemented by a single entity (e.g., a processor (CPU or DSP, etc.), an integrated circuit, etc.).
Fig. 6 schematically shows an illustrative flowchart of a base station power saving method performed in the base station management apparatus 3000 of the embodiment of the present disclosure.
First, in step S3001, the number of users of the base station management apparatus 3000 and the configuration data reporting unit 3020 transmit the number of real-time users of the corresponding cell or cells and the configuration data of the cell to the base station energy saving device 2000 via the northbound interface, for example, every predetermined time, for example, 10 minutes or 15 minutes, or in response to an inquiry request from the base station energy saving device 2000.
Next, in step S3002, the energy saving performing unit 3030, upon receiving the control command for turning on or off one or more cells transmitted by the base station energy saving device 2000, transmits the control command to the base station corresponding to the target cell. Then, in step S3003, the energy saving execution unit 3030 receives the command execution result for the above-described control command from the base station, and transmits the command execution result to the base station energy saving device 2000 via, for example, the northbound MML command interface, and then ends the processing.
According to the base station management device of the exemplary embodiment of the disclosure, since the base station energy saving policy is set in the base station energy saving device, the base station management device only reports the grasped real-time user number and configuration data of each target cell to the base station energy saving device, and transparently transmits the energy saving control command and the command execution result through the northbound MML command line interface, no additional setting is added for energy saving and emission reduction of the base station, and the overall structure is not complicated.
Application examples according to the present disclosure are described below.
As an application example 1, a scheme of applying the base station energy saving technology of the present disclosure to different scenes such as colleges and universities, business circles, subways, and the like may be considered. According to different busy and idle degrees of the cells in an application scene, a timing energy-saving mode (timing on or off of the cells) and a dynamic energy-saving mode (dynamically turning on or off the cells according to busy and idle conditions of the cells) can be adopted. In addition, under the 1.8G and 2.1G dual-frequency band same-coverage scenes of colleges and universities, business circles, subways and the like, the inventor tests a timing energy-saving mode and a dynamic energy-saving mode. The result shows that the business district is busy in day and night, so the time for taking energy-saving measures is short; colleges and middle-position communities in the holiday period are idle in the daytime and at night, and the energy-saving time can be set to be very long; the idle time of the cells in the scenes of high-speed rails, subways and the like is relatively fixed. Therefore, in general, the change of the number of users in the cells in scenes such as high-speed rails, subways, colleges and universities in the holiday period is regular, so that the energy-saving mode is reasonable in timing, and the number of users in scenes such as colleges and universities, business circles, stadiums, rural areas and the like is relatively unstable, so that the dynamic energy-saving mode is reasonable correspondingly.
In addition, as application example 2, a scheme of applying the base station power saving technology of the present disclosure to a 5G cellular mobile communication network may be considered. In a 5G mobile network, the power of the base station is more than 5 times larger than that of an LTE base station in a 4G mobile network, and the power of a single AAU is about 600 watts, so if energy saving is enabled at night, more electricity can be saved. Fig. 7 illustrates a power saving effect when the base station power saving technology of the present disclosure is applied to a 5G network. As can be seen from fig. 7, when the base station energy saving technique of the present disclosure is applied in a 5G mobile network, a single AAU can save energy by about 1.5 degrees at night, calculated in 6 hours.
