With the continuous expansion of the 4G/5G network scale, the network user group is rapidly increased, so that the energy consumption of equipment is continuously increased, and the energy consumption cost is one of the most main expenditure expense of network operators. In order to promote energy conservation and emission reduction, reduce energy consumption cost and promote the transformation of industrial development modes, research on 4G/5G network energy conservation technology is urgently needed.

Currently, the main part of the energy consumption of the 4G base station device is the power consumption of the RRU (Remote Radio Unit ), and the main part of the energy consumption of the 5G base station device is the power consumption of the AAU (Active Antenna Unit ). Therefore, the key for reducing the energy consumption of the equipment is how to improve the working efficiency of the RRU/AAU and reduce the power consumption of the RRU/AAU.

In order to solve the above-described problems, the present exemplary embodiment first provides a power saving control method of a mobile communication network. Referring to fig. 1, the energy saving control method of the mobile communication network may include the steps of:

s110, acquiring the coverage type of the mobile communication network of each cell and the scene type corresponding to each cell.

S120, obtaining each load level interval of the mobile communication network, and determining a load level time domain corresponding to each cell in each load level interval according to the coverage type.

And S140, obtaining a target energy-saving time domain corresponding to the cell in each load level interval according to the intersection of the load level time domain corresponding to the cell in each load level interval and the scene energy-saving time domain.

And S150, in the target energy-saving time domain corresponding to each load level interval, carrying out energy-saving control on the mobile communication network of the cell through energy-saving measures corresponding to the cell.

In practical application, by the energy-saving control method of the mobile communication network in the exemplary embodiment of the present disclosure, the problem of device energy saving of a 5G NSA (Non-independent networking mode) architecture base station and a 5G SA (independent networking mode) architecture base station can be better solved.

The above steps of the present exemplary embodiment will be described in more detail with reference to fig. 2 to 4.

In step S110, a coverage type of the mobile communication network of each cell and a scene type corresponding to each cell are acquired.

In the present exemplary embodiment, a cell, which is also referred to as a cell, refers to an area covered by one of base stations or a part of the base stations (sector antennas) in a cellular mobile communication system, in which a mobile station can reliably communicate with the base stations through a wireless channel.

The coverage type of a cell refers to a type of a wireless communication network included on a base station covering the cell, and in particular, when a communication band includes a 4G basic band, a 4G other band, and a 5G band, the coverage type of the cell may include a 4G basic band single coverage type, a 4G multi-band same coverage type, and a 4G and 5G band same coverage type. The coverage type of a cell may be determined according to different base station types.

For example, for the 4G reference cell, assuming that the 4G base band is the 4G 1.8 band and the 4G other band is the 4G 2.1 band, the coverage type of the 4G 1.8 band may include the following 3 types: the 4g1.8 band is covered solely, 4g1.8+4g2.1 is covered identically and 4g1.8+4g2.1+5g is covered identically.

In this exemplary embodiment, as shown in fig. 2, the method for obtaining the coverage type of the mobile communication network of each cell may specifically include the following steps:

s210, obtaining base station types of a mobile communication network of each cell, wherein the base station types comprise an indoor distribution system and an outdoor macro base station.

Before determining the coverage type of a cell, it is first necessary to acquire the base station type of the cell mobile communication network. In this example embodiment, the base station types include an indoor distribution system and an outdoor macro base station.

The indoor distribution system is a scheme for improving the mobile communication environment in a building aiming at indoor user groups, and utilizes the indoor antenna distribution system to uniformly distribute signals of a mobile base station at each corner in a room, so that an indoor area is ensured to have ideal signal coverage.

The outdoor macro base station is a wireless signal transmitting base station of a communication operator, the coverage distance of the macro base station is large, the coverage distance of the 4G macro base station is generally about 0.5Km-1Km, and the coverage distance of the 5G macro base station is about 0.5 Km. The outdoor macro base station is suitable for areas with scattered traffic in suburbs and has the characteristics of omni-directional coverage and higher power.

For two base station types, namely an indoor distribution system and an outdoor macro base station, different cell coverage type judging methods are required to be used.

S220, when the base station type of the cell is an indoor distribution system, acquiring indoor distribution engineering parameters of the cell in each communication frequency band, and determining the coverage type of the cell according to the indoor distribution engineering parameters of each communication frequency band.

In this example embodiment, the indoor distributed engineering parameters may mainly include: site name, site latitude and longitude, coverage type, installation location, coverage location, etc. For any two indoor distribution systems, if the above parameters of the respective communication bands are identical, it can be considered that the communication bands are covered identically.

Specifically, the method for determining the coverage type of the cell according to the indoor distribution engineering parameters of each communication frequency band may be: if the indoor distribution engineering parameters corresponding to the cell in the 4G basic frequency band, the 4G other frequency bands and the 5G frequency band are the same, determining the coverage type of the cell as the same coverage type of the 4G frequency band and the 5G frequency band; if the indoor distribution engineering parameters corresponding to the cell in the 4G basic frequency band and the other 4G frequency bands are the same, determining the coverage type of the cell as the same coverage type of the 4G multi-frequency band; if the indoor distribution engineering parameters of the cell in the 4G basic frequency band are different from those of other 4G frequency bands and/or 5G frequency bands, determining the coverage type of the cell as the independent coverage type of the 4G basic frequency band.

S230, when the base station type of the cell is an outdoor macro base station, acquiring engineering parameters of the outdoor macro base station of the cell in each communication frequency band, acquiring measurement report data of the cell in each communication frequency band according to a preset measurement period, and determining the coverage type of the cell according to the engineering parameters of the outdoor macro base station and the measurement report data.

In this example embodiment, the outdoor macro base station engineering parameters may include: station name, station longitude and latitude, coverage type, installation position, antenna hanging height, antenna azimuth angle, antenna mechanical downtilt angle and the like.

Measurement report data, i.e., MR (Measurement Report ) data, is data that can be used for network evaluation and optimization in the field of mobile communications. In the present exemplary embodiment, the coverage type of the outdoor macro base station may be determined by judging the coincidence ratio between MR data of the respective communication bands.

For any two outdoor macro base stations, engineering parameters are extracted, and the coincidence ratio of MR data is calculated according to the longitude and latitude reported by a mobile user under different communication frequency bands, the distance from a user terminal to the base station and the azimuth angle. And if the engineering parameters of the outdoor macro base stations are consistent and the coincidence degree of the MR data is greater than a certain coincidence degree threshold, considering that the two outdoor macro base stations with different communication frequency bands are covered by the same.

Specifically, the method for determining the coverage type of the cell according to the engineering parameters of the outdoor macro base station and the measurement report data may be: if the corresponding outdoor macro base station engineering parameters of the cell in the 4G basic frequency band, the other 4G frequency bands and the 5G frequency band are the same, and the overlapping ratio of the measurement report data is greater than or equal to a data overlapping ratio threshold value, determining the coverage type of the cell as the same coverage type of the 4G frequency band and the 5G frequency band; if the engineering parameters of the outdoor macro base station corresponding to the cell in the 4G basic frequency band and the other 4G frequency bands are the same, and the coincidence degree of the measurement report data is greater than or equal to a data coincidence degree threshold value, determining the coverage type of the cell as a 4G multi-frequency band same coverage type; if the outdoor macro base station engineering parameters of the cell in the 4G basic frequency band are different from those of the outdoor macro base station engineering parameters of the other 4G frequency bands and/or the 5G frequency band, or the overlapping degree of the measurement report data of the 4G basic frequency band and the other 4G frequency band and/or the 5G frequency band is smaller than a data overlapping degree threshold, determining the coverage type of the cell as the single coverage type of the 4G basic frequency band.

When calculating the overlap ratio of MR data, the system needs to periodically acquire the MR data of base stations with different communication frequency bands according to a preset measurement period to calculate the overlap ratio of MR data.

For example, assume that MR data reported in the 4g 1.8 communication band is taken as a reference cell, and the number of all MR data collected in a period of time is M, where main parameters include: site name, site latitude and longitude, MR azimuth, MR-to-base station distance.

Meanwhile, the number of MR data reported by the 4G 2.1 communication frequency band is N (the total data of N and M is equivalent), and the main parameters of acquisition include: site name, site latitude and longitude, MR azimuth, MR-to-base station distance. And comparing the MR data reported by the 4G 2.1 communication frequency band with the MR data of the reference cell one by one, marking the MR data within the range of the reference cell as overlapping, otherwise marking the MR data as non-overlapping, and sequentially calculating the overlapping ratio. If the overlap ratio is higher than the data overlap ratio threshold, such as 80%, the 4g2.1 communication frequency band is considered to be covered by the same frequency band as the 4g1.8 communication frequency band.

By the same method, whether the cell is of the same coverage type of the 4G and 5G frequency bands can also be judged, so that the specific method is not repeated here.

In addition, the scene type corresponding to the cell refers to the type of the actual scene contained in the cell, for example, the scene type may include office building, mall, college, residential district, underground parking lot, scenic spot, etc., and since some scenes have specificity, some fixed time periods in some scenes may not be suitable or allowed to perform energy saving control, and therefore in actual operation, it is necessary to determine the energy saving time of the cell in combination with the scene type.

In step S120, each load level interval of the mobile communication network is acquired, and a load level time domain corresponding to each cell in each load level interval is determined according to the coverage type.

In this example embodiment, the load index may be divided into a plurality of level intervals, and different energy saving measures may be taken for different load level intervals. For example, the load index may be divided into 4 level intervals, and a specific division manner may be, for example, a load index of less than 20% is a first load level interval, a load index of 20% to 40% is a second load level interval, a load index of 40% to 70% is a third load level interval, and a load index of greater than 70% is a fourth load level interval. And if the load index is in the first to third load level intervals, corresponding energy-saving measures can be taken for the mobile communication network of the cell, and if the load index is in the fourth load level interval, the load index indicates that the cell network is busy, and no energy-saving measures can be selected.

In this example embodiment, the load index of the cell is continuously in a period of a certain load class interval, that is, a load class time domain corresponding to the load class interval.

In this exemplary embodiment, as shown in fig. 3, determining, according to the coverage type, a load level time domain corresponding to each cell in each load level interval may specifically include the following steps:

and S310, acquiring historical load data of each cell according to the preset time granularity, and acquiring load indexes of each cell in each preset time granularity according to the historical load data.

In this example embodiment, the preset time granularity refers to a unit interval time for acquiring load data, and may be 15 minutes, 30 minutes, 45 minutes, or 60 minutes. After the historical load data of each cell is obtained according to the preset time granularity, a corresponding load index can be obtained through calculation according to the historical load data, and a database is established for storing the historical load index of the equipment.

S320, obtaining a load level time period of which the time length of the historical load index of the cell lasting in the load level interval is greater than or equal to a preset time threshold according to the load index of the cell in each preset time granularity.

By counting historical load index data of a cell and marking out time periods when the load index is continuously in a certain load level interval, taking a union of the time periods as a load level time period of the cell corresponding to the load level interval.

For example, if the preset time granularity is 15 minutes, the threshold corresponding to each load class interval may be:

a) Load index within 15 minutes is less than 20%;

b) The load index within 15 minutes is more than or equal to 20 percent and less than 40 percent;

c) The load index within 15 minutes is greater than or equal to 40% and less than 70%;

d) The load index is greater than or equal to 70% within 15 minutes.

And then counting the duty ratio in a time-sharing period according to the threshold to obtain a corresponding duty class period.

S330, obtaining a load grade time domain corresponding to the load grade interval of each cell in the coverage type according to the intersection of the load grade time periods corresponding to the load grade interval of all cells in the same coverage type.

And for all the cells with the same coverage type, taking the intersection of the cells in the load class time periods corresponding to the load class intervals, and taking the obtained intersection as the load class time domain corresponding to the load class intervals of the cells.

In step S130, energy saving measures corresponding to the cells are determined according to the coverage types of the cells, and scene energy saving time domains corresponding to the cells are determined according to the scene types of the cells.

In this example embodiment, the energy saving measures corresponding to the cells may be determined according to different coverage types, and may specifically include: if the coverage type of the cell is the single coverage type of the 4G basic frequency band, the energy-saving measures corresponding to the cell comprise channel energy saving and symbol energy saving; if the coverage type of the cell is the 4G multi-band same coverage type, the energy-saving measures corresponding to the cell comprise equipment power-down energy saving, carrier energy saving, channel energy saving and symbol energy saving; if the coverage type of the cell is the same coverage type of 4G and 5G frequency bands, the energy-saving measures corresponding to the cell comprise equipment power-down energy saving, carrier energy saving, channel energy saving, symbol energy saving and 5G wave beam energy saving.

For example, for several types of cells, including a 4g1.8 frequency band single coverage, 4g1.8+4g2.1 identical coverage and 4g1.8+4g2.1+5g identical coverage, the energy saving measures corresponding to the cells are determined according to the specific characteristics of the cells with different coverage types.

For cells with the 4G1.8 frequency band single coverage type, since the 4G1.8 reference cells provide network reference coverage, in order to ensure basic communication requirements, equipment power-down operation cannot be implemented in most scenes. But for special scenarios, for example: a building, stadium, etc., can be powered down with the device for a particular period of time. The scene mainly adopts channel energy-saving and symbol energy-saving measures, and corresponding energy-saving operation is implemented in a specified time period.

For cells of the same coverage type as 4g1.8+4g2.1, the 4g1.8 reference cell provides reference coverage, 4g2.1 provides hot spot coverage, and the scenario mainly adopts measures of power-down energy conservation, carrier energy conservation, channel energy conservation and symbol energy conservation of the device, and implements corresponding energy-saving operation in a specified time period.

For cells of the same coverage type as 4g1.8+4g2.1+5g, the 4g1.8 reference cell provides reference coverage, 4g2.1 and 5G provide hot spot coverage, the scenario mainly adopts the measures of power-down energy saving, carrier energy saving, channel energy saving, symbol energy saving and 5G beam energy saving of the device, and implements corresponding energy saving operation in a specified time period.

In addition, in this exemplary embodiment, the corresponding scene energy-saving time domain needs to be determined according to the specific scene type of the cell, so as to ensure that the specific energy-saving control time can be more accurately determined in some special scenes.

In step S140, a target energy-saving time domain corresponding to each load level interval of the cell is obtained according to the intersection of the load level time domain corresponding to each load level interval of the cell and the scene energy-saving time domain.

In this example embodiment, the target energy-saving time domain corresponding to the cell in each load class interval is obtained by intersecting the load class time domain corresponding to the cell in each load class interval with the scene energy-saving time domain, so that the coverage type, the load condition and the specific scene type of the cell are combined, and the energy-saving control time period with stronger applicability for different cells is obtained.

In step S150, in the target energy saving time domain corresponding to each load level interval, energy saving control is performed on the mobile communication network of the cell through the energy saving measures corresponding to the cell.

In this example embodiment, the power-down and energy-saving manner of the device is as follows: and for other frequency band cells except the 4G basic frequency band, taking an intersection of a first load level time domain and a scene energy-saving time domain of the cell, powering down RRU/AAU equipment at the starting moment of each continuous time in the intersection, and powering up the powered-down equipment at the ending moment of each continuous time in the intersection. Further, the power-down energy saving of the equipment can be realized based on an intelligent switch of the Internet of things, and the intelligent switch is arranged on a power supply circuit of the equipment and is communicated with a remote control host through a cell base station.

Specifically, an intelligent turn-off module of the internet of things can be installed at the communication equipment, the intelligent turn-off module is connected with 4G equipment and 5G equipment in a divided-multiple way mode, the system remotely and automatically sets the turn-off module to trip and switch on according to a preset time period, and the turn-on and turn-off of the 4G equipment and the 5G equipment are controlled to achieve the purposes of energy conservation and consumption reduction. The power-down energy-saving of the equipment can be realized in the following two modes:

(1) And (5) performing on-line power-on and power-off operations in real time.

For example, the 4g1.8 communication band is a reference coverage cell, and thus is not subjected to a power-down operation. And the system master station issues a device power-down command and transmits the command through the Internet of things. And after receiving the instruction, the remote turn-off module respectively performs power-down operation on the 4G 1.8, 4G 2.1 and 5G devices which are covered in the same way.

And the system master station issues a device power-on command and transmits the command through the Internet of things. And after receiving the instruction, the remote turn-off module respectively performs power-on operation on the 4G 1.8, 4G 2.1 and 5G devices which are covered in the same way.

(2) Power-up and power-down operations are predetermined.

For example, the system issues a power-down command and a power-down time in advance, and issues a power-up command and a power-up time at the same time, both commands appear in pairs. The remote shutdown module performs the above operations within a contracted time, thereby realizing 4G 1.8, 4G 2.1 and 5G equipment shutdown and energy saving.

In this exemplary embodiment, the carrier energy saving manner is: and in the second load class time domain, the user is forbidden to access or switch into other frequency bands except the basic frequency band in the same coverage area, the user of the other frequency bands is switched to the basic frequency band which is covered by the same, and the carrier wave of the other frequency bands which are not used by the user is closed.

For example, when the 4G 1.8, 4G 2.1 and 5G cells are in different frequency networking and the same coverage scene, the same covered different frequency cells are divided into a reference cell and an energy-saving cell, when the system judges that the load of the whole cell is smaller than a set threshold, the base station prohibits new users from accessing and switching into the energy-saving cell, and switches all users on the cell into the reference cell covered by different frequencies, and after no user is in the energy-saving cell, the carrier frequency of the cell is closed, thereby achieving the purposes of energy saving and consumption reduction.

In this example embodiment, the channel energy saving mode is: and for the 4G equipment, in a third load level time domain, inquiring the states of all channels of the RRU, and closing idle channels except the first channel by closing the power supply of the power amplifier of the corresponding channel.

For example, when the load of the 4G 1.8 and 4G 2.1 cells is light, the aim of closing part of the transmitting channels of the corresponding RRU/AAU of the cell is achieved by controlling the starting and the switching-off of the RRU/AAU power amplifier. And after the increase of the service load is detected, the intelligent turn-off mode is exited, and the original channel emission state is recovered, so that the purposes of energy saving and consumption reduction are achieved by controlling the starting and the turn-off of the RRU power amplifier.

In this exemplary embodiment, the symbol energy saving method is as follows: and in the first to third load level time domains, for the RRU/AAU channel still in operation, downlink data is scheduled to a specific symbol, and the power supply of the power amplifier of the channel is closed in the rest symbol time without effective information transmission.

For example, the 4g1.8, 4g2.1 and 5G cells are not in the state of maximum traffic at any time during actual communication, so for the symbols in the subframe, no time is filled with valid information. The symbol-level energy saving is to close the power amplifier source at the moment of no effective data emission so as to achieve the purpose of energy saving. When the symbol-level energy-saving function is not started, the power amplification source of the RRU is in an open state at any moment; after the symbol-level energy-saving function is started, the system actively dispatches downlink data to a designated symbol according to the business busyness degree through business data volume prediction, and the power amplifier power supply is turned off in the rest symbol time without effective information transmission, so that the energy-saving purpose is achieved.

In this example embodiment, the manner of 5G beam energy saving is: and in the time domain of the first to third load levels, the current forming weight of the 5G antenna to each user is obtained, and then the current forming total weight of the 5G antenna to all users is obtained in a summation mode. Comparing the current shaping total weight of the 5G antenna with a set threshold value, and if the current shaping total weight is smaller than the threshold value, judging that the 5G antenna is a low-energy-efficiency antenna. And selecting target antennas with the current forming total weight less than the set threshold value, namely the antennas with lower efficiency, and controlling the corresponding channels of all the antennas with low energy efficiency to enter dormancy, thereby realizing 5G beam energy saving, reducing the energy consumption of the base station and achieving the aim of improving the energy efficiency of the whole base station.

In this example embodiment, an energy-saving time period database may be established according to the target energy-saving time domain and the measure field corresponding to each load level interval, and then, by acquiring energy-saving data in the database, a corresponding energy-saving control operation may be performed. Meanwhile, a mobile base station coverage scene library is established by newly establishing base station engineering information, corresponding scene energy-saving time is set by combining the scene coverage type of a cell, and differential energy-saving measures are adopted for different scenes, so that the energy-saving effect is maximized. Different measure fields may be set for different base station types.

The main parameters of the outdoor macro base station include: site type, site name, site longitude and latitude, coverage type (4g1.8, 4g2.1, 5G), coverage scene major class, coverage scene minor class, installation location, antenna hang-up, antenna azimuth, antenna mechanical downtilt, scene characteristics, recommended energy saving time period, recommended energy saving measure.

For example: outdoor macro base station, zoo in city a, (114.403, 38.201), (4g1.8, 4g2.1), scenic spot, tourist area workbench 2, 40 m, 120 degree, 3 degree, (9 to 17 points in scenic spot time period, network load is higher, other scenic spot non-tourist time period, user is basically zero), (0 to 9 points, 18 to 24 points), (in energy-saving time period, 4g2.1 device intelligently powers down, 4g1.8 turns off one channel of RRU, only another channel is left, and in other time period, 4g1.8, 4g2.1 device turns on symbol energy saving).

Then, taking the case of the three coverage cases of the single coverage of the 4g1.8 frequency band, the same coverage of 4g1.8+4g2.1 and the same coverage of 4g1.8+4g2.1+5g as an example, in combination with the specific energy saving time period and energy saving measures, the target energy saving time domain and measure field may include: site type, site name, site latitude and longitude, coverage type (4g1.8, 4g2.1, 5G), coverage scene class, coverage scene subclass, installation location, threshold a recommended energy saving time period, threshold a recommended energy saving measure, threshold b recommended energy saving time period, threshold b recommended energy saving measure, threshold c recommended energy saving time period, threshold c recommended energy saving measure, threshold d recommended energy saving time period, threshold d recommended energy saving measure.

In this example embodiment, after the cell executes the corresponding energy-saving measure, the current load index of the cell may also be obtained in real time, and when the load index is deteriorated, a corresponding energy-saving wake-up measure is taken, and specifically, the step of energy-saving wake-up may include:

and S410, when the cells perform energy-saving control, acquiring current load indexes of the cells in real time according to the preset time granularity.

In this example embodiment, the current network load condition of each cell is monitored by acquiring the current load index of each cell in real time and feeding back the current load index.

And S420, when the current load index of the cell is greater than or equal to the overload index threshold, restoring the cell and other cells with the same coverage type as the cell to the mobile communication network state when no energy-saving measures are used.

For example, when the load index reaches 70%, it may be determined that the overload index threshold is exceeded. Due to the real-time performance and burstiness of the mobile network, the system judges whether to cancel the energy-saving measures or not according to the feedback result, restores the original network, and ensures that the mobile network is quickly restored to the original level through a wake-up mechanism. If the load index exceeds the threshold, corresponding awakening measures are adopted for the cell and the cells with the same coverage type, and normal operation of the cell is restored.

For example, the system may read the system load index and the number of users of the 4G 1.8, 4G 2.1 and 5G cells at a time granularity of 15 minutes, 30 minutes, 45 minutes, 60 minutes, and when the device cell load with the energy saving measure exceeds 70%, the system takes the wake-up measure to restore the network capability.

Firstly, the current network load index of an energy-saving cell is read, whether the existing energy-saving measure comprises equipment power-down operation is judged, if the load exceeds 70%, and the power-down and power-up modules are called if the load is in a power-down state in the 4G 2.1 and 5G frequency bands, a power-up command is sent, and the network function of the non-reference cell is recovered.

Secondly, the current network load index of the energy-saving cell is read, whether the existing energy-saving measure comprises carrier energy saving is judged, if the load exceeds 70%, the cell is not a reference cell, and the 4G 2.1 carrier is in a closed state, a carrier energy-saving module is called, a carrier starting command is sent, and the network function of the 4G 2.1 frequency band is recovered.

Thirdly, the current network load index of the energy-saving cell is read, whether the existing energy-saving measure comprises channel energy saving is judged, if the load exceeds 70%, and the 4G 1.8 and 4G 2.1 channels are in a closed state, a channel energy saving module is called, a channel opening command is sent, and the network channel functions of the 4G 1.8 and 4G 2.1 frequency bands are restored.

Fourth, the current network load index of the energy-saving cell is read, whether the existing energy-saving measures comprise carrier energy saving is judged, if the load exceeds 70%, and the 4G 1.8 and 4G 2.1 adopt symbol energy saving, a symbol energy saving module is called, a symbol recovery command is sent, and the network symbol functions of 4G 1.8 and 4G 2.1 frequency bands are recovered.

Fifthly, the current network load index of the energy-saving cell is read, whether the existing energy-saving measure comprises 5G beam energy saving is judged, if the load exceeds 70%, a 5G beam energy saving module is called, a beam recovery command is sent, and the 5G network beam function is recovered.

In addition, in this exemplary embodiment, the effect of the cell after energy saving may be evaluated, and the energy saving time period and the energy saving measure may be adjusted periodically according to the evaluation result. And aiming at a coverage scene of a certain cell, reading complaint data and performance index data of the scene at an operator, comparing the changes of complaint quantity and performance index data before and after implementation of energy-saving measures, and dividing a time period of increasing the complaint quantity or deteriorating the performance index into a next grade load time domain corresponding to a larger load index from a current grade load time domain.

Specifically, the system compares complaint data of the same scene and judges whether the implementation of the energy-saving measures causes the increase of user complaints. By comparing KPI (Key Performance Indicator, key performance index) and KQI (Key Quality Indicators, key quality index) data of the same scene, judging whether the implementation of energy-saving measures causes network quality deterioration, dynamically evaluating energy-saving effects and feeding back, and adjusting corresponding energy-saving time periods and energy-saving measures.

For example, the system compares the change of complaint quantity before and after the implementation of the energy-saving measures by reading the complaint data of the operators and associating the complaint data with the energy-saving cells, and if the increase of the complaint quantity is due to unreasonable time period setting, feeds back an energy-saving time period selection module and modifies the corresponding energy-saving time period; if the complaint quantity is increased due to unreasonable energy-saving measures, the energy-saving time period selection module is fed back, and the corresponding energy-saving measures are modified.

Meanwhile, the system compares the change of the performance indexes before and after implementation of the energy-saving measures by reading the network performance data of the operator and associating the network performance data with the energy-saving cells, feeds back the energy-saving time period selection module if the performance indexes are poor due to unreasonable time period setting, modifies the corresponding energy-saving time period, feeds back the energy-saving time period selection module if the performance indexes are poor due to unreasonable energy-saving measure setting, and modifies the corresponding energy-saving measures.

If the complaint quantity and the performance index are permanently deteriorated, the energy-saving measure and the energy-saving time period can not be improved by modifying, the energy-saving judging module is fed back, and the energy-saving measure of the cell is canceled.

In this example embodiment, through measures of network wakeup and feedback evaluation, the problem of network quality degradation caused by cell energy saving can be corrected in time, and a user is ensured to have better network experience as much as possible.
