In addition, the network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not constitute a limitation to the technical solution provided in the embodiment of the present application, and it can be known by a person skilled in the art that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

To facilitate an understanding of the present application, the related art to which the present application relates will now be described.

Fig. 1 is a schematic diagram of a network architecture to which the technical solution provided by the embodiment of the present application is applied. Wherein, can include in this network: a terminal device, a Radio Access Network (RAN) or AN access communication network (AN) (RAN and AN are collectively referred to as (R) AN), and a Core Network (CN).

The terminal device may be a device with a wireless transceiving function. The terminal equipment may be referred to by different names, such as User Equipment (UE), access equipment, terminal unit, terminal station, mobile station, remote terminal, mobile equipment, wireless communication equipment, terminal agent, or terminal device. The terminal equipment can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal device comprises a handheld device, a vehicle-mounted device, a wearable device or a computing device with wireless communication function. For example, the terminal device may be a mobile phone (mobile phone), a tablet computer, or a computer with wireless transceiving function. The terminal device may also be a Virtual Reality (VR) device, an Augmented Reality (AR) device, an industrial control terminal, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in smart grid, a wireless terminal in smart city, a wireless terminal in smart home, etc. In this embodiment of the present application, the apparatus for implementing the function of the terminal device may be the terminal device, or may be an apparatus capable of supporting the terminal device to implement the function, such as a chip system. In the present application, the chip system may have a chip configuration, and may also include a chip and other discrete devices.

The (R) AN mainly comprises access network equipment. The access network equipment may also be referred to as a base station. The base station may include various forms of base stations. For example: macro base stations, micro base stations (also referred to as small stations), relay stations, access points, etc. The method specifically comprises the following steps: the Base Station may be an Access Point (AP) in a Wireless Local Area Network (WLAN), a Base Transceiver Station (BTS) in a Global System for Mobile Communications (GSM) or Code Division Multiple Access (CDMA), a Base Station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA), an Evolved Node B (eNB, eNodeB) in LTE, or a relay Station or Access point, or a Base Station in a vehicle-mounted device, a wearable device, and a Next Generation Node B (The Next Generation Node B, gbb) in a 5G Network, or a Base Station in a future-evolution Public Land Mobile Network (PLMN) Network.

A base station generally includes a Base Band Unit (BBU), a Radio Remote Unit (RRU), an antenna, and a feeder for connecting the RRU and the antenna. Wherein, the BBU is used for being responsible for signal modulation. The RRU is responsible for radio frequency processing. The antenna is responsible for the conversion between guided waves on the cable and space waves in the air. On one hand, the length of a feeder line between the RRU and the antenna is greatly shortened by the distributed base station, so that the signal loss can be reduced, and the cost of the feeder line can also be reduced. On the other hand, the RRU and the antenna are smaller, so that the RRU can be installed anywhere, and the network planning is more flexible. Besides RRU remote, BBUs can be centralized and placed in a Central Office (CO), and the centralized mode can greatly reduce the number of base station rooms, reduce the energy consumption of supporting equipment, particularly air conditioners, and reduce a large amount of carbon emission. In addition, after the scattered BBUs are collected and become the BBU baseband pool, unified management and scheduling can be realized, and resource allocation is more flexible. In this mode, all physical base stations evolve into virtual base stations. All virtual base stations share information of data receiving and sending, channel quality and the like of users in a BBU baseband pool, and cooperate with each other to realize joint scheduling. In some deployments, a base station may include a Centralized Unit (CU) and a Distributed Unit (DU). The base station may also include an Active Antenna Unit (AAU). The CU realizes part of the functions of the base station and the DU realizes part of the functions of the base station. For example, the CU is responsible for processing non-real-time protocols and services, and implementing functions of a Radio Resource Control (RRC) layer and a Packet Data Convergence Protocol (PDCP) layer. The DU is responsible for processing a physical layer protocol and a real-time service, and implements functions of a Radio Link Control (RLC), a Media Access Control (MAC), and a Physical (PHY) layer. The AAU implements part of the physical layer processing functions, radio frequency processing and active antenna related functions. Since the information of the RRC layer eventually becomes or is converted from the information of the PHY layer, the higher layer signaling, such as RRC layer signaling or PDCP layer signaling, can also be considered to be sent by the DU or from the DU + AAU under this architecture. It is understood that in the embodiment of the present application, the access network device may be a device including one or more of a CU node, a DU node, and an AAU node. In addition, a CU may be divided into network devices in the RAN, or may be divided into network devices in a Core Network (CN), which may not be limited herein.

The core network includes a plurality of core network elements (alternatively referred to as network function network elements), for example, in fig. 1, the core network in a fifth Generation mobile communication technology (5th-Generation, 5G) system includes: an access and mobility management (AMF) network element, a Session Management Function (SMF) network element, a PCF network element, a User Plane Function (UPF) network element, an application function (application function) network element, an AUSF network element, and a UDM network element.

In addition, the core network may also include some network elements not shown in fig. 1, such as: a security anchor function (SEAF) network element, an authentication credential repository, and an authentication authorization and processing function (ARPF), which are not described herein in detail in the embodiments of the present application.

With the development of mobile communication networks, the energy consumption of wireless networks is getting larger and larger, and the demands of operators on energy conservation and consumption reduction are also more urgent. In the energy consumption composition of the wireless network, the energy consumption ratio of the base station equipment is the highest, the base station energy saving is the basis of the wireless network energy saving, and the base station energy saving technology is also a research hotspot in the industry.

In order to reduce the energy consumption of base station equipment, energy saving technologies such as symbol turn-off, channel turn-off, cell turn-off, deep sleep and the like are proposed in the industry, and the basic principle is to turn off part of hardware resources of a base station when a network is idle, so that the energy saving effect is achieved. Triggering of various energy-saving technologies needs to be judged based on service load, and if the service load of the base station is lower than a preset energy-saving triggering threshold and meets an energy-saving triggering condition, the corresponding energy-saving technology can be executed and the corresponding energy-saving state is entered.

As shown in fig. 2, after the base station enters the symbol off state, all the radio frequency channels of the base station are turned off within the idle symbol time without service data transmission, and all the radio frequency channels are turned on within the symbol time with service data transmission. As shown in fig. 3, the channel shutdown is to shut down part of the radio frequency channels of the base station when the traffic load of the base station is low, so as to save the energy consumption of the base station.

As shown in fig. 4, the cell switching-off technology is mainly used in a scenario where a plurality of base stations simultaneously cover the same area, where one base station is used as a coverage base station, and other base stations are planned as capacity layer base stations, and there is a same coverage relationship among the base stations in the area. The cell switching-off technology switches off all radio frequency channels by judging the traffic of each base station in a coverage area and taking the base station with lower traffic load as an energy-saving base station so as to achieve the aim of saving energy. In order to avoid the influence of cell switching on the service in the coverage area, a compensation base station needs to be configured for the energy-saving base station to be switched off, and before the cell switching off, users under the base station to be switched off are transferred to the compensation base station in a switching mode, so that the service connection is kept uninterrupted. The configuration of the energy-saving base station and the compensation base station can be determined based on an operator networking strategy and preset on the base station side, and generally, the capacity layer base station is used as the energy-saving base station, and the covering layer base station is used as the compensation base station. Deep sleep further turns off more hardware resources such as a digital baseband chip of the base station on the basis of cell turn-off so as to save more energy consumption.

When a base station energy-saving technology is deployed in a wireless network at present, energy-saving trigger thresholds need to be preset for all base stations in an energy-saving area, and if a certain base station meets an energy-saving trigger condition, a corresponding energy-saving state is entered; the triggering and execution of the energy-saving technology of each base station are carried out independently, unified management and control are lacked, the cooperative energy conservation among the base stations is not supported, and the optimization of regional energy consumption cannot be realized.

On the other hand, in the existing cell turn-off and deep sleep energy saving technology, the energy saving base station and the compensation base station are statically configured, and are generally determined based on the same coverage relation and preset on the base station side, for example, the overlay base station is determined as the compensation base station, and the capacity layer base station is used as the energy saving base station; after the energy-saving base station is switched off or is in dormancy, the compensation base station receives the original service under the energy-saving base station, so that the compensation base station cannot enter an energy-saving state even if the energy-saving trigger condition is met; in an actual network, energy consumption and service characteristics of different base stations are different, and energy-saving benefits brought by the execution of an energy-saving technology are different; the existing configuration method of the energy-saving base station and the compensation base station cannot flexibly determine the energy-saving base station and the compensation base station based on the service and energy consumption change conditions of the base stations, so that the base station with low energy-saving benefit may enter an energy-saving state, and the base station with high energy-saving benefit as the compensation base station cannot execute the energy-saving technology, thereby causing power waste and influencing the regional energy-saving benefit.

In view of the foregoing problems, embodiments of the present application provide a method for saving energy for a base station, where a first traffic load of each base station in a target area that needs to save energy in a historical time period (may be referred to as a "first time period") is obtained, and a candidate energy saving list of each base station in a second time period after the first time period is predicted according to the first traffic load, so as to determine an energy saving mode used by each base station in the second time period. Therefore, which energy-saving modes are adopted for energy saving after the base station can be determined according to the historical operating conditions of the base stations, and then the base stations in the target area interact to realize the cooperative energy saving among the base stations and enlarge the energy-saving benefit.

Fig. 5 is a schematic diagram of a system structure provided in an embodiment of the present application. The target area includes a plurality of base stations (illustratively, base station 1, base station 2, and base station 3), and the plurality of base stations are respectively connected to the energy saving control device. The energy-saving control equipment can perform information interaction with a plurality of base stations, determine the energy-saving mode adopted by the base stations according to the information from each base station, and send indication information to the base stations so that the base stations operate according to the determined energy-saving mode.

The energy-saving control device may be a separate device entity, or may be integrated in an existing base station device, a core network device, or a network management device, and an information interaction interface exists between the energy-saving control device and each base station in a target area.

The following describes a method for saving energy of a base station according to an embodiment of the present application, by taking a schematic system structure diagram shown in fig. 5 as an example. It should be noted that fig. 5 only shows one possible system structure to which the embodiment of the present application can be applied, and when the embodiment of the present application is implemented specifically, the system structure may also be adjusted according to practical situations, and the present application may not be limited thereto.

As shown in fig. 6, the base station energy saving method may include:

s101, the first base station acquires first load information.

The first load information is used for reflecting the service load of the first base station in the first time period.

The first base station may be any base station in the target area. For example, in the system configuration shown in fig. 5, each of the base stations 1, 2, and 3 acquires the first load information corresponding thereto.

In one implementation, the first load information includes a traffic load index of each unit time interval in the first time period; the service load index comprises one or more of the utilization rate of the physical resources of the cell, the number of the connected users and the service flow.

Wherein the first time period may be set based on a demand of a traffic prediction algorithm. For example, the period may be set to 7 to 30 days. The unit time interval is the time granularity of the base station side statistical traffic load index, and for example, the unit time interval may be set to 15 minutes or 1 hour, and the like. Wherein the first time period includes a plurality of unit time periods.

S102, the first base station determines a candidate energy-saving scheme list according to the first load information.

And the candidate energy-saving scheme list comprises the energy-saving technology corresponding to the first base station in the second time period. The second time period is subsequent to the first time period.

Specifically, after the first base station acquires the first load information, the first base station may acquire the service load of the first base station in each time period within the first time period, and then predict the working state of the first base station within the second time period according to the information, and plan the energy saving technology corresponding to the first base station within the second time period in advance.

For example, if the traffic load of the first base station in the first time period is large, the network service quality may be prevented from being reduced by setting the energy saving technology corresponding to the first base station in the second time period to an energy saving technology that does not have a large influence on the performance of the base station, such as null or symbol off; for another example, if the traffic load of the first base station in the first time period is small, the energy saving technology that can reduce energy consumption better by setting the energy saving technology corresponding to the first base station in the second time period to cell off or deep sleep may be used to achieve a better energy saving effect.

In one implementation, S102 may specifically include:

and S1021, the first base station determines second load information according to the first load information.

And the second load information is used for determining the traffic load of the first base station in the second time period. In one possible design, the second load information may include a traffic load index for each unit time period within the second time period.

Optionally, determining the second load information according to the first load information includes: and determining second load information according to the first load information by adopting a time series prediction algorithm.

For example, the first base station uses the traffic data in the first time period as training data, and inputs the training data into a prediction algorithm to obtain a traffic load index in the second time period.

And S1022, the first base station determines a candidate energy-saving scheme list according to the second load information.

Optionally, determining a candidate energy saving scheme list according to the second load information, where the candidate energy saving scheme list includes: and determining a candidate energy-saving scheme list according to the energy-saving strategy information and the second load information.

The energy-saving strategy information comprises energy-saving technologies, energy-saving triggering conditions and a turn-off threshold value which are supported by the first base station; the power saving techniques include one or more of deep sleep, cell off, channel off, and symbol off. The energy saving technology supported by the first base station may be understood as the energy saving technology supported by the first base station on hardware or an underlying application.

For example, the energy saving policy information may be preset on the base station side. For another example, the energy saving policy information may also be issued to the base station by the core network device. The present application is not limited thereto.

In one possible design, determining the candidate energy saving scheme list according to the energy saving policy information and the second load information may include one or more of the following S1-S4:

s1, if the first base station satisfies the first energy-saving triggering condition in the first time period of the second time period, determining that the energy-saving technology corresponding to the first base station in the first time period includes a deep sleep technology. The first time period is determined as an energy-saving time period corresponding to the first base station.

The first time period comprises any time period in the second time period; the first energy saving triggering condition includes: the service load index of the first base station is lower than a preset first threshold, and the duration is greater than a preset second threshold.

S2, if the first base station meets the second energy-saving triggering condition in the second time period within the second time period, determining that the energy-saving technology corresponding to the first base station in the second time period includes a cell turn-off technology. The second time interval is determined as the energy-saving time interval corresponding to the first base station.

Wherein the second time period comprises any time period in the second time period; the second energy saving trigger condition includes: the service load index of the first base station is lower than a preset first threshold, and the duration is between a preset second threshold and a third threshold; the second threshold is greater than the third threshold.

And S3, if the first base station meets a third energy-saving triggering condition in a third time period within the second time period, determining that the energy-saving technology corresponding to the first base station in the third time period comprises a channel shutdown technology. The third time interval is determined as the energy-saving time interval corresponding to the first base station.

Wherein the third time period comprises any time period within the second time period; the third energy-saving trigger condition includes: the service load index of the first base station is lower than a preset first threshold, and the edge service load is lower than a preset fourth threshold; the edge traffic load is used for reflecting a ratio of the number of measurement reports of which the signal strength measurement value of the first base station in the first time period is smaller than a preset fifth threshold value to the total number of the measurement reports in the first time period.

The edge traffic load may be defined as a ratio of the number of measurement reports in which the signal strength measurement value of the serving cell is smaller than a preset fifth threshold value in the first time period to the total number of measurement reports in the first time period; specifically, a first base station acquires a serving cell signal strength measurement report periodically reported by each UE in a first time period, where the serving cell signal strength measurement report carries a serving cell signal strength measurement value (RSRP) measured by the UE; and determining the edge service load value by counting the total number of the measurement reports in the first time period and the number of the measurement reports of which the signal strength measurement value of the serving cell is smaller than a preset fifth threshold value.

In the above design, when determining the third triggering condition, not only the size of the service load of the base station is considered, but also the service distribution condition is considered, and the channel is triggered to be turned off only under the condition that the edge service load is small, so that the problems that the coverage of the base station is shrunk, the edge user cannot access or the service performance is reduced after the channel is turned off can be avoided.

And S4, if the first base station meets a fourth energy-saving triggering condition in a fourth time period within the second time period, determining that the energy-saving technology corresponding to the first base station in the fourth time period comprises a symbol turn-off technology. And the fourth time period is determined as the energy-saving time period corresponding to the first base station.

The fourth time period comprises any time period in the second time period; the fourth energy saving triggering condition includes: the service load index of the first base station is lower than a preset first threshold value.

S103, the first base station sends the candidate energy-saving scheme list to the energy-saving control equipment.

And the candidate energy-saving scheme list is used for instructing the energy-saving control equipment to determine the energy-saving mode adopted by the first base station in the second time period according to the candidate energy-saving scheme list.

The energy saving mode adopted by the base station in a period of time may reflect information such as energy saving technology and corresponding energy saving time that the base station may execute in the period of time.

In one implementation, the method may further include:

s104, the first base station acquires the base station energy-saving identification and sends the base station energy-saving identification to the energy-saving control equipment.

And when the candidate energy-saving scheme list is empty and when the candidate energy-saving scheme list is not empty, the assignment of the base station energy-saving identifier is different.

The base station energy saving flag may be understood to indicate whether the base station may perform the energy saving technique during the second time period. For example, if the candidate energy saving scheme list of the base station is not empty, the base station energy saving identifier is set to 1, and the base station is identified as an energy saving candidate base station; and if the base station does not meet any energy-saving triggering condition in the second time interval or the base station does not support any energy-saving technology, setting the energy-saving identifier of the base station to be 0 and identifying the base station as a non-energy-saving base station.

By sending the base station energy-saving identifier to the energy-saving control equipment, the energy-saving control equipment can read the base station energy-saving identifier so as to determine whether the base station can execute the energy-saving technology; if not, the energy-saving control device may not read the candidate energy-saving scheme list corresponding to the base station any more, so as to improve efficiency.

In the method, after the first base station sends the candidate energy-saving scheme list, or sends the candidate energy-saving scheme list and the base station energy-saving identifier to the energy-saving control equipment, the energy-saving control equipment can determine the energy-saving mode adopted by each base station in the N base stations in the second time period according to the candidate energy-saving scheme list corresponding to each base station in the target area.

Corresponding to the above-described operation process on the base station side, the operation process of the energy-saving control apparatus is described below:

s105, the energy-saving control equipment obtains a candidate energy-saving scheme list corresponding to each base station in the N base stations in the target area.

Specifically, S105 may be implemented by a method in which each of N base stations in the target area sends the first message to the energy saving control device. The first message may carry energy saving information such as a base station identifier, a candidate energy saving scheme list, a base station energy saving identifier, and the like.

The candidate energy-saving scheme list corresponding to any base station comprises the energy-saving technology corresponding to any base station in the second time period; the candidate energy-saving scheme list corresponding to any base station is determined by the first load information; the first load information is used for reflecting the service load of any base station in the first time period.

And S106, the energy-saving control equipment determines the energy-saving mode adopted by each base station in the N base stations in the second time period according to the candidate energy-saving scheme list corresponding to each base station in the N base stations.

In one implementation, S106 may include:

s1061, the energy-saving control equipment determines candidate base stations containing deep sleep or cell turn-off technology in the corresponding candidate energy-saving scheme list according to the candidate energy-saving scheme list corresponding to each base station in the N base stations to obtain a first candidate base station set.

Optionally, the method provided in the embodiment of the present invention further includes: acquiring a base station energy-saving identifier corresponding to each base station in N base stations in a target area; and when the candidate energy-saving scheme list of the corresponding base station is empty and the candidate energy-saving scheme list of the corresponding base station is non-empty, the assignment of the base station energy-saving identifier is different. Further, S1061 may include:

and determining candidate base stations comprising deep dormancy or cell cut-off technology in the corresponding candidate energy-saving scheme list according to the candidate energy-saving scheme list corresponding to each base station in the N base stations and the base station energy-saving identification to obtain a first candidate base station set.

For example, if the energy saving identifier of a certain base station is 1 and the candidate energy saving scheme list includes a deep sleep or cell turn-off technology, the base station is recorded in the first candidate base station set; and sequentially traversing each base station in the N base stations to obtain a first candidate base station set.

S1062, the energy-saving control device determines a paired base station corresponding to each first candidate base station in the first candidate base station set.

The pairing base station corresponding to the first candidate base station includes: a base station satisfying a condition of a compensating base station as a first candidate base station; the first candidate base station comprises any base station in the first candidate base station set.

The base station that satisfies the condition of the compensating base station as the first candidate base station may include: and the base station has the same coverage area with the first candidate base station, supports the same service type with the first candidate base station, and has the sum of the average service flow with the first candidate base station smaller than the maximum service flow supported by any one of the two base stations.

The information of the same coverage relation between the base stations can be preset in the energy-saving control equipment or determined based on the longitude and latitude and azimuth information of the base stations.

And S1063, the energy-saving control equipment performs preset processing on each first candidate base station in the first candidate base station set in sequence to obtain a processing result.

Wherein the preset treatment comprises: if the first candidate base station does not have a corresponding pairing base station, removing deep sleep and cell turn-off technologies from a candidate energy-saving scheme list of the first candidate base station; if the first candidate base station has the corresponding matched base station, selecting one base station from the matched base stations corresponding to the first candidate base station as the compensation base station of the first candidate base station, determining the first candidate base station as the first energy-saving base station, and adding the first energy-saving base station and the compensation base station of the first energy-saving base station into the first energy-saving base station set.

For example, after it is determined that there is no corresponding paired base station in the first candidate base station and the deep sleep and cell shutdown techniques are removed from the candidate energy saving scheme list of the first candidate base station, the energy saving control device may send the updated candidate energy saving scheme list to the corresponding first candidate base station by sending a fourth message to the first candidate base station, so that the first candidate base station updates its candidate energy saving scheme list based on the fourth message.

In addition, optionally, if there is a corresponding paired base station in the first candidate base station, selecting one base station from the paired base stations corresponding to the first candidate base station as the compensation base station of the first candidate base station may be implemented in the following manner:

if the non-energy-saving base station exists in the paired base stations, determining the non-energy-saving base station as a compensation base station of the first candidate base station; otherwise, determining the base station with the maximum energy efficiency parameter value or the minimum service load index corresponding to the first time period as a compensation base station of the first candidate base station; the non-energy-saving base station is determined according to the base station energy-saving identification corresponding to each base station in the N base stations in the target area.

Optionally, the method further includes: acquiring energy efficiency parameter values respectively corresponding to each base station in the N base stations; the energy efficiency parameter value is positively correlated with the importance of the base station, and the energy efficiency parameter value is negatively correlated with the energy consumption of the base station. Further, S1063 may specifically include:

and according to the sequence of the energy efficiency parameter values corresponding to the base stations from small to large, sequentially presetting each candidate base station in the first candidate base station set to obtain a processing result.

The importance of the base station may be reflected in at least one of a traffic load, an average traffic flow, a maximum traffic flow supported by the base station, and a number of supported traffic types.

The service load may include one or more combinations of parameters such as PRB resource utilization, the number of RRC connection users, and average service traffic; the service types supported by the base station can be preset at the base station side and comprise voice service, common data service, ultra-low time delay high reliability data service or private network service and the like.

For example, the energy-saving control device may send a second message to all base stations in the target area according to a preset period, so as to obtain the energy-saving parameters reflecting the importance of each base station. And after receiving the second message, each base station in the target area sends a third message to the energy-saving control equipment. And the third message carries the base station identification and the energy-saving parameter of the base station in the first time period.

And S1064, the energy-saving control equipment determines the energy-saving mode adopted by each base station in the N base stations in the second time period according to the processing result.

The energy-saving mode comprises the first energy-saving base station set and a second energy-saving base station set; and the base stations in the second energy-saving base station set do not support the deep sleep or cell switch-off technology in the second time period. The second set of energy-saving base stations is a set of base stations except the first set of energy-saving base stations in the N base stations.

The method supports energy-saving technologies for various base stations, and supports different trigger priority sequences aiming at different types of energy-saving technologies; because the energy-saving benefit of cell turn-off or deep sleep is higher than that of symbol turn-off or channel turn-off, the method can preferentially trigger cell turn-off and deep sleep by preferentially determining the energy-saving base stations meeting the conditions of cell turn-off and deep sleep and the corresponding compensation base stations, and the energy-saving benefit is improved.

Optionally, after the energy saving control device determines the energy saving mode used by each base station in the second time period, the method may further include:

s107, the energy-saving control equipment determines a target energy-saving scheme list.

The target energy-saving scheme list comprises energy-saving technologies, corresponding energy-saving time periods and corresponding compensation base station identifications of all first energy-saving base stations in the first energy-saving base station set in the second time period, and energy-saving technologies and corresponding energy-saving time periods of all base stations in the second energy-saving base station set in the second time period.

And S108, the energy-saving control equipment controls the target energy-saving base station to execute the energy-saving technology according to the target energy-saving scheme list in the second time period.

For example, the energy-saving control device sends a fifth message to the target energy-saving base station, and sends the target energy-saving scheme list to the corresponding base station; and the fifth message carries information such as the target energy-saving base station identifier, the target energy-saving scheme list and the like.

And the target energy-saving base station executes corresponding candidate energy-saving technologies in the candidate energy-saving time periods respectively. Specifically, each first energy-saving base station in a first energy-saving base station set executes a deep sleep or cell turn-off technology in a corresponding energy-saving time period, and triggers a user under a first candidate base station to migrate to a compensation base station of the first candidate base station; and the base stations in the second energy-saving base station set execute channel cut-off or symbol cut-off technology in the corresponding energy-saving time period.

In the method, for the base station meeting the cell shutdown or deep dormancy triggering condition, the optimal energy-saving base station and the optimal compensation base station are dynamically determined based on the base station service and the energy consumption parameters by the base station pairing method, so that the total energy consumption of a target area is reduced; specifically, when the energy-saving base station is determined, the base station with the smaller energy efficiency value is preferentially determined as the energy-saving base station by defining a base station energy efficiency parameter; because the energy efficiency value of the base station is smaller, the energy consumption is larger, the service flow is smaller, the energy-saving benefit can be improved by preferentially switching off the base station with the smaller energy efficiency value, the influence on the original service under the energy-saving base station and the compensation base station is reduced, and the network performance is improved; on the other hand, when the compensation base station is determined, the non-energy-saving base station or the base station with the largest energy efficiency value and the smallest service load is preferentially determined as the compensation base station, so that other base stations which meet the energy-saving triggering condition or have smaller energy efficiency values can preferentially enter an energy-saving state, and the total energy consumption of the area is reduced to the greatest extent; meanwhile, after the base station is turned off or is dormant, the original service needs to be migrated to the compensation base station, and the base station with the minimum service load is selected as the compensation base station, so that the service migration requirement can be met, and network problems such as congestion of a compensation cell are avoided; in addition, for the base station meeting the triggering condition of cell shutdown or deep sleep, if the compensation base station does not exist, the base station is limited to enter a cell shutdown or deep sleep state in a mode of updating the candidate energy-saving scheme list, the condition that an original user cannot access the network after the base station is shut down or is in sleep is avoided, and user experience is guaranteed.

In the method, when determining the associated base station group formed by the energy-saving base station and the compensation base station, the coverage relation between the base stations is considered, and the service type and the service volume of the base stations are considered, so that the compensation base station and the energy-saving base station support the same service type, the capacity carrying capacity of the compensation base station can meet the service flow requirements of the energy-saving base station and the compensation base station, and the service access of a user is not influenced after the energy-saving base station is turned off or is dormant. In addition, when the energy-saving mode of each base station is determined, the cell cut-off and deep sleep technology can be preferentially executed by preferentially determining the first energy-saving base station meeting the cell cut-off and deep sleep conditions and then determining the second energy-saving base station set meeting the channel cut-off and symbol cut-off conditions, so that the energy-saving benefit is improved.

The method supports energy-saving technologies of various base stations, and supports different trigger priority sequences aiming at different types of energy-saving technologies; because the energy-saving benefit of cell turn-off or deep sleep is higher than that of symbol turn-off or channel turn-off, the method can preferentially trigger cell turn-off and deep sleep by preferentially determining the energy-saving base stations meeting the conditions of cell turn-off and deep sleep and the corresponding compensation base stations, and the energy-saving benefit is improved.
