Description

Technical Field

[0001] This application relates to the field of wireless communication technology, specifically to a service-adaptive base station energy-saving method, apparatus, medium, and product. Background Technology

[0002] The power consumption of 5G base stations is mainly divided into two parts: the active antenna unit (AAU) and the baseband processing unit (BBU). Under full load, the AAU accounts for approximately 90% of the total power consumption, becoming the main component of base station power consumption. Therefore, AAU energy saving has always been a major research direction for base station energy saving. To reduce AAU power consumption, the industry has developed various energy-saving technologies, such as subframe silence, channel silence, shallow sleep, deep sleep, and extreme sleep. These technologies achieve energy-saving effects by shutting down different devices and using different shutdown methods; as more devices are shut down, the energy-saving effect increases accordingly.

[0003] Currently, deploying the aforementioned energy-saving functions requires manual configuration of corresponding switches and thresholds. This not only increases operational complexity but may also lead to configuration errors or omissions, resulting in complex energy-saving function configurations. Furthermore, some energy-saving functions conflict during configuration, preventing the simultaneous and optimal application of various energy-saving technologies. This limits further improvements in energy efficiency and creates conflicts between some energy-saving functions. Each energy-saving technology currently has its own independent shutdown method, lacking a unified intelligent shutdown strategy to ensure user experience while reducing power consumption. This often leads to a contradiction between energy-saving effects and user experience in practical applications, requiring operators to perform meticulous optimization and balancing, resulting in a lack of a unified intelligent shutdown strategy and poor consistency. Summary of the Invention

[0004] At least one embodiment of this application provides a service-adaptive base station energy-saving method, apparatus, medium, and product to solve the problems of complex energy-saving function configuration, conflicting energy-saving functions, and lack of unified intelligent shutdown strategies in the prior art.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, embodiments of this application provide a service-adaptive base station energy-saving method, comprising:

[0007] Based on the wake-up duration of the active antenna element of the base station, the shutdown level supported by the active antenna element is determined, and the shutdown level includes multiple levels with different durations.

[0008] The active antenna unit is shut down based on the current network load, service assurance requirements, and the shutdown level supported by the active antenna unit.

[0009] Optionally, the shutdown levels include:

[0010] A time-slot-level shutdown with a wake-up time less than or equal to one time slot; the time-slot-level shutdown is used to shut down all service scheduling, and the total response time for the activation and deactivation of the active antenna unit is less than or equal to one time slot for the active antenna unit.

[0011] A second-level shutdown with a wake-up time of less than or equal to one second; the second-level shutdown is used to shut down the active antenna unit whose total response time for turning on and off is less than or equal to one second.

[0012] A minute-level shutdown with a wake-up time of less than or equal to one minute; the minute-level shutdown is used to shut down the active antenna element whose total response time for turning on and off is less than or equal to one minute.

[0013] Optionally, the step of shutting down the active antenna unit based on the current network load, service assurance requirements, and the shutdown level supported by the active antenna unit includes:

[0014] Obtain the first current network load status of the target cell within the first assessment period;

[0015] If the first existing network load condition is greater than or equal to the first threshold value, the time slot level shutdown is selected when the active antenna unit supports the time slot level shutdown.

[0016] If the first existing network load is less than the first threshold, the second-level shutdown or the minute-level shutdown is selected based on the service guarantee requirements and the shutdown level supported by the active antenna unit.

[0017] Optionally, when the active antenna element supports the time slot level shutdown, after selecting the time slot level shutdown, the method further includes:

[0018] In the traffic channel, subframe muting is performed on downlink symbols that have no data transmission;

[0019] If the bandwidth utilization rate is lower than the first threshold when there is a symbol for data transmission, symbol-level centralized scheduling will be performed in a time slot, and all services will be aggregated to the first N symbols for data transmission in each time slot, while the unused symbols will be turned off.

[0020] If the load of the current time slot is lower than the second threshold, the corresponding radio frequency channel is shut down; wherein, after the shutdown of some radio frequency channels takes effect, the power of the shut-down channels is compensated by power boosting.

[0021] Alternatively, in a broadcast channel, services can be preferentially scheduled to the symbols occupied by the public signals on the symbols used for public signal transmission.

[0022] Optionally, after selecting the second-level shutdown or the minute-level shutdown, the method further includes:

[0023] If the first current network load is less than the first threshold, obtain the second current network load of the neighboring cells adjacent to the target cell and the target cell;

[0024] If the second current network load condition is greater than or equal to the second threshold value, the step of obtaining the first current network load condition of the target cell within the first evaluation period is executed.

[0025] If the second existing network load is less than the second threshold, obtain the first service guarantee requirements of the target cell and the adjacent cells;

[0026] If the first service guarantee requirement is met, the users of the target cell are migrated to the adjacent cell, and the second-level shutdown is selected; if the first service guarantee requirement is not met, the step of obtaining the first current network load status of the target cell within the first evaluation period is executed.

[0027] Optionally, after migrating users from the target cell to the neighboring cell and selecting the second-level shutdown, provided that the first service guarantee requirement is met, the method further includes:

[0028] After entering the second-level shutdown, it is obtained whether the real-time access users of the adjacent cells meet the second service guarantee requirements;

[0029] If the second service guarantee requirement is not met, the second-level shutdown will be exited, and the target user in the adjacent cell will be migrated to the target cell.

[0030] If the second business assurance requirement is met, the second evaluation cycle will begin.

[0031] If the second evaluation cycle begins and continues for a preset duration, and the second current network load is less than the second threshold value, then the minute-level shutdown is selected.

[0032] Optionally, after selecting the minute-level shutdown, the method further includes:

[0033] After selecting the minute-level shutdown, the third current network load status of the adjacent cells is determined based on the third evaluation period;

[0034] When the third network load condition is greater than or equal to the third threshold value, control the neighboring cells to interact with the target cell, execute the target cell wake-up process and exit the minute-level shutdown process;

[0035] If the third current network load condition is less than the third threshold value, the step of determining the third current network load condition of the neighboring cells based on the third evaluation period continues.

[0036] Secondly, embodiments of this application provide a service-adaptive base station energy-saving device, comprising:

[0037] The first determining module is used to determine the shutdown level supported by the active antenna unit based on the wake-up duration of the active antenna unit of the base station. The shutdown level includes multiple levels with different durations.

[0038] The first processing module is used to shut down the active antenna unit according to the current network load, service assurance requirements, and the shutdown level supported by the active antenna unit.

[0039] Thirdly, embodiments of this application provide a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the method described in the first aspect.

[0040] Fourthly, embodiments of this application provide a computer program product, including computer instructions, which, when executed by a processor, implement the steps of the method described in the first aspect.

[0041] Compared with existing technologies, the service-adaptive base station energy-saving method, apparatus, medium, and product provided in this application determine the shutdown level based on the wake-up duration of the active antenna unit (AAU) of the base station. This automatic partitioning method based on hardware characteristics enables the base station to automatically identify and adapt to different shutdown strategies without the need for manual judgment of the applicable scenarios for each energy-saving function. The shutdown level supported by the AAU is directly determined based on the wake-up duration, reducing manual intervention and configuration complexity. Through the above-mentioned intelligent shutdown strategy, the configuration and adjustment of energy-saving functions can be completed automatically without manual intervention, thereby greatly reducing the complexity of configuration.

[0042] The proposed solution can also dynamically adjust the shutdown level of the AAU based on the existing network load. During off-peak periods, if the AAU supports minute-level shutdown and service assurance requirements are not high, the AAU will enter deep sleep or extreme sleep mode, significantly reducing power consumption. During peak periods, the solution ensures that the AAU is in normal working condition or only performs time-slot-level shutdown with minimal impact on network performance, ensuring a good user experience. In this way, it achieves both power reduction and improved user experience, overcoming the deficiency of existing technologies that lack a unified intelligent shutdown strategy.

[0049] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, without limiting the number of objects; for example, the first object can be one or more. Furthermore, "or" in this application indicates at least one of the connected objects.

An indirect instruction can be understood as one in which the receiver determines the corresponding information based on the instruction sent by the sender, or makes a judgment and determines the operation to be performed or the requested result, etc., based on the judgment result.

[0051] It should be noted that, currently, the thresholds for channel shutdown, shallow hibernation, deep hibernation, and extreme hibernation are consistent, and the load assessment cycle is around 5 minutes. When deploying and applying various energy-saving functions, there will be corresponding switches and threshold configuration requirements based on their energy-saving characteristics, which need to be manually set and operated. Moreover, some energy-saving functions conflict during configuration, making it impossible to maximize the application of various energy-saving technologies. Currently, each energy-saving technology has its own shutdown method, lacking a unified intelligent shutdown strategy that can reduce power consumption while ensuring user experience.

[0052] As described in the background section, existing technologies suffer from problems such as complex energy-saving function configurations, conflicts among some energy-saving functions, and a lack of unified intelligent shutdown strategies. To address at least one of these problems, this application provides a service-adaptive base station energy-saving method, device, medium, and product that can reduce or avoid the occurrence of the above situations, achieve adaptive, intelligent, and extreme shutdown, and ensure user experience while reducing power consumption.

[0053] Please refer to Figure 1 This application provides a service-adaptive base station energy-saving method, comprising:

[0054] Step 11: Determine the shutdown level supported by the active antenna unit based on the wake-up duration of the active antenna unit of the base station. The shutdown level includes multiple levels with different durations.

[0055] In this embodiment, the base station performs detailed measurement and analysis of the AAU's wake-up duration, conducting a wake-up duration analysis. Wake-up duration refers to the time required for the AAU to transition from a dormant state to normal operation. Based on the wake-up duration analysis, the shutdown levels supported by the AAU are divided into several different duration levels. These levels may include instant wake-up (short shutdown time, almost immediately resuming operation), short-time wake-up (slightly longer shutdown time, but still within an acceptable recovery time), and long-time wake-up (long shutdown time, requiring a longer recovery time), thereby determining the shutdown level and providing technical support for subsequent shutdown selection. Each level corresponds to different energy-saving effects and potential network performance impacts.

[0056] Step 12: Based on the current network load, service assurance requirements, and the shutdown level supported by the active antenna unit, shut down the active antenna unit.

[0057] In this embodiment, the base station monitors the network load in real time, including the number of users, traffic volume, and service type, and performs a comprehensive evaluation based on service assurance requirements (such as the priority and latency requirements of specific services). Based on the analysis results of the network load and service assurance, and the shutdown levels supported by the AAU determined in step 11, the base station intelligently selects the most suitable shutdown level to shut down the AAU. For example, when the network load is low and service demand is not urgent, a shutdown level with a long wake-up time can be selected to achieve the best energy-saving effect; while when the network load is high or service demand is urgent, an immediate wake-up shutdown level is selected to ensure network response speed. This process is a dynamic adjustment process; the base station adjusts the AAU shutdown level in real time according to changes in network load and service demand to ensure maximum energy saving while meeting service requirements. The method in this application, by comprehensively considering the AAU wake-up time, the network load, and service assurance requirements, achieves intelligent shutdown control of the AAU, reducing base station energy consumption while ensuring network performance and service demand are met.

[0058] Optionally, the shutdown levels include:

[0059] A time-slot-level shutdown with a wake-up time less than or equal to one time slot; the time-slot-level shutdown is used to shut down all service scheduling, and the total response time for the activation and deactivation of the active antenna unit is less than or equal to one time slot for the active antenna unit.

[0060] A second-level shutdown with a wake-up time of less than or equal to one second; the second-level shutdown is used to shut down the active antenna unit whose total response time for turning on and off is less than or equal to one second.

[0061] A minute-level shutdown with a wake-up time of less than or equal to one minute; the minute-level shutdown is used to shut down the active antenna element whose total response time for turning on and off is less than or equal to one minute.

[0062] It should be noted that in 5G NR, the duration of a time slot is typically around 1 millisecond. However, the specific length of a time slot may vary depending on the parameter set (such as subcarrier spacing and cyclic prefix). For example, as the subcarrier spacing increases, the duration of the time slot decreases by 1 / 2. In a typical configuration, a subframe (1 millisecond in length) can consist of multiple time slots, the number of which depends on the specific parameter set configuration1. Each time slot typically contains multiple OFDM symbols used for data transmission.

[0063] It should also be noted that the active antenna unit (AAU) includes, but is not limited to, devices such as power amplifiers, transceivers, digital intermediate frequency (IF) units, BBLs, and optical modules. Based on the wake-up duration of these devices, they are classified into three types of shutdown: time slot level, second level, and minute level.

[0064] In this embodiment, time-slot-level shutdown is a highly efficient energy-saving technology that can achieve energy-saving effects by completing all service scheduling and device activation and deactivation within a single time slot without affecting user experience.

[0065] This application's slot-level shutdown is applicable to both single-layer and multi-layer 5G network scenarios. Compared to traditional symbol-based shutdown technology, slot-level shutdown not only enables device shutdown and activation within finer-grained time units but also allows for differentiated shutdown processing based on different channels, thus more effectively ensuring user experience. While traditional symbol-based shutdown technology can achieve symbol-level shutdown, channel shutdown has a certain impact on network performance during application, currently typically with load assessment taking effect and exiting within minutes (generally around 5 minutes), and only supports shutting down half of the channels. In contrast, this application's slot-level shutdown can quickly respond to changes in service scheduling and device status within a single time slot, achieving more refined energy-saving control.

[0066] Furthermore, the time-slot-level shutdown in this application also needs to consider compensation measures such as power boosting to ensure energy-saving effects are achieved without affecting network performance. By comprehensively applying time-slot-level shutdown technology and compensation measures such as power boosting, network energy efficiency and user experience can be further improved.

[0067] Second-level or minute-level shutdown offers deeper granularity compared to time-slot-level shutdown, but the target base station cannot provide service after shutdown, thus limiting its applicability. While increasing the number of shutdown devices improves energy efficiency, it also extends the wake-up time. Second-level or minute-level shutdown allows for device activation and deactivation responses within a second or minute timeframe. This deeper granularity, compared to time-slot-level shutdown, means controlling device switching over a longer timescale. However, this deeper granularity also introduces a significant limitation: the target base station cannot provide service during shutdown. Therefore, second-level or minute-level shutdown is primarily suitable for multi-layered network scenarios with shared coverage, where multiple base stations or access points cover the same area, ensuring that other base stations continue to provide service even when one base station is shut down, thus not affecting normal user experience.

[0068] From an energy-saving perspective, as the number of devices shut down increases, the energy-saving effect also improves. This is because more devices do not consume power when shut down, thus reducing the overall system energy consumption. However, this also brings another problem: increased wake-up time. When service needs to be restored, these shut-down devices need to be woken up one by one, and the wake-up process for each device requires a certain amount of time. Therefore, in second- or minute-level shutdown technologies, a balance needs to be found between energy-saving effect and wake-up time to ensure that energy-saving requirements are met without excessively prolonging the wake-up time, which would affect the system's response speed and user experience.

[0069] For example, in scenarios with low traffic and low latency sensitivity, such as a 5G base station located in an area with low nighttime activity, like an industrial park, where factories shut down at night, base station traffic drops significantly. The active antenna unit of the base station is tested, and its wake-up time meets the requirements for minute-level shutdown. According to step 11, it is determined that the active antenna unit supports minute-level shutdown. Current network load data shows extremely low traffic, and the services in this area mainly consist of background data transmission tasks, which are not sensitive to latency, and the service assurance requirements are relatively low. Combined with step 12, the base station controller, based on the current network load, service assurance requirements, and the minute-level shutdown level supported by the active antenna unit, controls the active antenna unit to enter deep sleep mode. During deep sleep, most RF hardware is shut down, with only a small amount of necessary monitoring circuitry remaining, greatly reducing the base station's power consumption. When a new service request arrives, although waking up the active antenna unit requires a certain amount of time (around minutes), because the service is not sensitive to latency, it will not significantly impact the user experience.

[0070] For example, in a scenario with moderate traffic volume and certain latency requirements, a 5G base station in a commercial area experiences moderate traffic volume during the daytime, primarily involving users browsing web pages and watching short videos. Testing shows that the wake-up time of the base station's active antenna unit meets the conditions for second-level shutdown. Following step 11, it is confirmed that the base station supports a second-level shutdown. Current network load monitoring indicates moderate traffic volume, and while users have certain latency requirements, they are not extremely stringent. According to step 12, the base station controller, based on the current network load, service assurance requirements, and the second-level shutdown level, controls the active antenna unit to enter a shallow sleep state. During shallow sleep, some non-critical radio frequency channels are shut down. When a new service is accessed, the active antenna unit can quickly wake up within seconds to respond promptly to service requests. This achieves a certain degree of energy saving while effectively meeting users' latency requirements, ensuring a positive user experience.

[0071] For example, in scenarios with high traffic volume and extremely high latency requirements, such as during a sporting event in a large stadium, 5G base stations carry a large amount of real-time high-definition video streaming and high-speed data transmission for on-site audiences. Testing revealed that the wake-up time of the active antenna unit could reach the standard for time-slot-level shutdown. Based on step 11, it was determined that it supports the time-slot-level shutdown level. The current network load is high, and service assurance requirements are extremely high; any latency could affect the user experience of watching live streams or using data services. Combining step 12, the base station controller monitors downlink data in real time during service transmission based on the current network load, service assurance requirements, and the time-slot-level shutdown level, and executes the shutdown policy according to the time-slot-level shutdown. This ensures that network coverage and signal quality are not affected, thus achieving a certain degree of energy saving while ensuring normal service operation in scenarios with high traffic volume and extremely high latency requirements.

[0072] This application proposes a service-adaptive intelligent shutdown strategy for base stations, which categorizes shutdown into three levels based on device wake-up time: time slot level, second level, and minute level. By considering the current network load and service assurance requirements, it achieves adaptive, intelligent, and optimized shutdown, reducing power consumption while ensuring user experience.

[0073] In an optional embodiment, shutting down the active antenna unit based on the current network load, service assurance requirements, and the shutdown level supported by the active antenna unit includes:

[0074] Obtain the first current network load status of the target cell within the first assessment period;

[0075] If the first existing network load condition is greater than or equal to the first threshold value, the time slot level shutdown is selected when the active antenna unit supports the time slot level shutdown.

[0076] If the first existing network load is less than the first threshold, the second-level shutdown or the minute-level shutdown is selected based on the service guarantee requirements and the shutdown level supported by the active antenna unit.

[0077] In this embodiment, the first network load status of the target cell within a first evaluation period (denoted as T1, where T1 can be minute-level detection, for example, one evaluation period per minute) is obtained. This step is the basis for shutdown decisions; by monitoring and analyzing the network load in real time, the current network load status can be understood. Next, the first network load status of the target cell within the first evaluation period is compared with a preset first threshold value:

[0078] If the first network load is greater than or equal to the first threshold, it indicates a heavy network load, and in this case, priority should be given to ensuring service continuity and stability. Therefore, if the active antenna unit supports time-slot-level shutdown, time-slot-level shutdown will be selected. Time-slot-level shutdown can achieve energy saving through fine-grained time management without affecting user experience, making it suitable for high-load scenarios.

[0079] If the initial network load is less than the first threshold, it indicates a light network load. In this case, while ensuring service requirements are met, more in-depth energy-saving measures can be considered. Depending on service requirements and the shutdown level supported by the active antenna unit, a second-level or minute-level shutdown can be selected. Compared to time-slot-level shutdown, these two shutdown methods offer deeper granularity and more significant energy-saving effects, but they must be implemented without impacting user experience.

[0080] This application enables intelligent shutdown management of active antenna units by real-time monitoring of the existing network load and combining service assurance requirements with the shutdown levels supported by the active antenna units. This ensures service continuity and stability while effectively reducing energy consumption.

[0081] Optionally, if the first existing network load is greater than or equal to the first threshold value, and the active antenna unit does not support the time slot-level shutdown, then since the active antenna unit itself does not support the time slot-level shutdown function, it is impossible to directly reduce energy consumption through time slot-level shutdown. To address the energy consumption problem caused by high load, it is possible to adjust network parameters, such as increasing base station transmit power, optimizing base station layout, or adopting more efficient spectrum utilization methods, to improve network capacity and coverage efficiency, thereby alleviating the energy consumption pressure caused by high load to some extent. Alternatively, refined network planning and optimization can ensure that network resources are fully utilized and unnecessary energy consumption is reduced. For example, the overall network performance can be improved through reasonable base station site selection and antenna configuration, as well as optimization of the transmission network structure, etc.

[0082] Optionally, when the active antenna element supports the time slot level shutdown, after selecting the time slot level shutdown, the method further includes:

[0083] In the traffic channel, subframe muting is performed on downlink symbols that have no data transmission;

[0084] If the bandwidth utilization rate is lower than the first threshold when there is a symbol for data transmission, symbol-level centralized scheduling will be performed in a time slot, and all services will be aggregated to the first N symbols for data transmission in each time slot, while the unused symbols will be turned off.

[0085] If the load of the current time slot is lower than the second threshold, the corresponding radio frequency channel is shut down; wherein, after the shutdown of some radio frequency channels takes effect, the power of the shut-down channels is compensated by power boosting.

[0086] Alternatively, in a broadcast channel, services can be preferentially scheduled to the symbols occupied by the public signals on the symbols used for public signal transmission.

[0087] In this embodiment of the application, when the active antenna unit supports time slot-level shutdown, after selecting time slot-level shutdown, it further includes performing subframe silencing processing on downlink symbols without data transmission in the service channel, performing symbol-level centralized scheduling when the bandwidth resource utilization rate is lower than a first threshold, performing radio frequency channel shutdown when the load is lower than a second threshold, and compensating through power boosting, or prioritizing the centralized scheduling of services to symbols occupied by common signals in the broadcast channel.

[0088] Furthermore, subframe silence processing is used to indicate that in the service channel, for downlink symbols with no data transmission, subframe silence processing is performed. This means that no data transmission occurs during these symbol periods without data transmission, thereby achieving energy saving. Specifically, when the 5G base station detects that some downlink symbols have no data transmission, it shuts down all radio frequency channels (power amplifiers, transceivers).

[0089] If, during a symbol time when data transmission is scheduled, the bandwidth utilization rate is below a first threshold, symbol-level centralized scheduling is performed within a time slot. This involves aggregating all services onto the first N (N is determined by the minimum number of symbols required for data transmission, and N is an integer) symbols in each time slot for data transmission, achieving symbol-level centralized scheduling, and shutting down any unused symbols. In this way, unnecessary energy consumption can be reduced while ensuring service transmission. For example, based on subframe silence, if the bandwidth utilization rate is low during a symbol time when data transmission is scheduled, symbol-level centralized scheduling can be performed within one time slot, aggregating all services onto the first few symbols of each time slot, thereby shutting down any unused symbols.

[0090] If the load of the current time slot is below a second threshold, the corresponding radio frequency (RF) channel is shut down. This means that when the load is low, some RF channels can be selectively shut down to further reduce power consumption. This can be understood as further evaluating the load of the current time slot based on symbol-level centralized scheduling. If the load is below a certain threshold, some RF channels can be shut down on symbols with data. By estimating the resource blocks (RBs) that need to be expanded after the RF channels are shut down, as many channels as possible can be shut down without increasing transmission time (within one slot).

[0091] Before shutting down a radio frequency (RF) channel, it's necessary to estimate the number of additional resource blocks (RBs) required after the shutdown. This is because shutting down an RF channel may result in some resources being underutilized, and therefore, it's necessary to compensate for this loss by adding RBs to ensure service continuity and transmission quality. To ensure no increase in transmission time (i.e., within a single slot), the scheduling strategy needs to be optimized. This includes rationally allocating RBs to different services and dynamically adjusting RB usage based on service demand and load conditions. By optimizing the scheduling strategy, as many RF channels as possible can be shut down without increasing transmission time. This not only reduces energy consumption but also improves network flexibility and scalability.

[0092] Optionally, after the partial RF channel shutdown takes effect, compensation is provided for the partial RF channels through power boosting. This is to ensure that sufficient signal coverage and transmission quality are maintained even after the partial RF channels are shut down. This application considers factors such as coverage; since a full RF channel shutdown cannot be performed on symbols with common signal transmissions, the partial channel shutdown can be flexibly configured. If it takes effect, compensation is required through power boosting to ensure basic coverage.

[0093] In broadcast channels, services are preferentially scheduled to the symbols occupied by the common signals. This approach utilizes the resources of the broadcast channel more efficiently while reducing interference and energy consumption on other service channels. In other words, services are preferentially scheduled to the symbols occupied by the common signals, maximizing the use of time-domain resources.

[0094] The above-described implementation process in this application is based on the active antenna element supporting slot-level shutdown, and further energy-saving measures are adopted. These measures can be dynamically adjusted according to the actual network load and service requirements to achieve more efficient energy utilization and lower energy consumption.

[0095] In practical applications, it is necessary to select appropriate energy-saving strategies based on the specific network environment and equipment configuration to ensure network stability and service continuity.

[0096] In one specific embodiment, reference is made to Figure 2 The diagram shown illustrates a signal transmission process, primarily demonstrating the downlink service signal transmission within a 5-millisecond time interval.

[0097] In this specific embodiment, taking a time slot comprising 14 downlink symbols as an example, for instance, the time axis 0-13 is used to identify the signal status at different time points. If downlink traffic occurs... Figure 2When symbols "1-4", "6", "7", and "12" have data to transmit, and other downlink symbols "6" to "13" have no data, this means that if data needs to be transmitted in the downlink symbols, the method of this application can try to centrally schedule these data sets to certain specific symbols, so as to perform energy-saving processing on symbols without data transmission, realize centralized service scheduling, and further consider shutting down some radio frequency channels to save energy when there is no data on the downlink symbols. Here, Figure 2 The "downlink symbol open" and "downlink symbol closed" states indicate whether the downlink symbol is opened or closed during downlink transmission, based on actual conditions, to control signal transmission and conserve energy. Data is transmitted according to resource availability.

[0098] Currently, the configuration thresholds for base station shutdown at the second or minute level are all the same. In live network deployments, each shutdown method can only take effect within its own defined time period, and the configuration times cannot overlap, lacking flexibility and hindering the optimal application of various shutdown technologies. Furthermore, the current evaluation strategy for entering shutdown only focuses on the target cell, neglecting the load of neighboring cells. If the load of neighboring cells is already high, the base station will be immediately woken up after shutdown, resulting in a ping-pong effect. Therefore, a service-adaptive progressive shutdown method is proposed. The base station adaptively enters second- or minute-level shutdown by evaluating the total load of the target cell and neighboring cells, as well as service guarantee requirements, while ensuring user experience.

[0099] In an optional embodiment, after selecting the second-level shutdown or the minute-level shutdown, the method further includes:

[0100] If the first current network load is less than the first threshold, obtain the second current network load of the neighboring cells adjacent to the target cell and the target cell;

[0101] If the second current network load condition is greater than or equal to the second threshold value, the step of obtaining the first current network load condition of the target cell within the first evaluation period is executed.

[0102] If the second existing network load is less than the second threshold, obtain the first service guarantee requirements of the target cell and the adjacent cells;

[0103] If the first service guarantee requirement is met, the users of the target cell are migrated to the adjacent cell, and the second-level shutdown is selected; if the first service guarantee requirement is not met, the step of obtaining the first current network load status of the target cell within the first evaluation period is executed.

[0104] In this embodiment, if the first current network load data of the target cell is less than a preset first threshold, the current load of the target cell is considered low, and a second-level shutdown or minute-level shutdown can be selected. After determining whether to select second-level shutdown or minute-level shutdown, the second current network load data of the adjacent cells and the target cell are obtained. If the second current network load data is greater than or equal to a preset second threshold, the first evaluation cycle continues. To further evaluate load changes or wait for a more suitable migration opportunity, if the second current network load data is less than the second threshold, the first service guarantee requirements of the target cell and adjacent cells are obtained. If the first service guarantee requirements are met, it means that the adjacent cells can realize the migration of users from the target cell, that is, the migration conditions are met, indicating that migrating users from the target cell will not have a significant impact on the user services of the target cell. Therefore, the users of the target cell will be migrated to the adjacent cells, and a second-level shutdown will be selected. If the first service guarantee requirements are not met, it means that the current conditions are not suitable for user migration, and the first evaluation cycle is entered to re-evaluate the feasibility of migration or wait for conditions to improve. Here, the first service guarantee requirements include, but are not limited to, evaluating whether the number of large-packet users and the perception rate are met.

[0105] Optionally, user equipment in the target cell can be reassigned to access points in adjacent cells via base station control commands, thus achieving user migration. After migration is complete, a second-level shutdown operation is performed on the target cell, shutting down some non-critical equipment or reducing equipment power consumption. If the first service guarantee requirement is not met, the first evaluation cycle begins, awaiting the next evaluation opportunity. During the first evaluation cycle, key indicators such as the current network load and service guarantee requirements of the target cell and adjacent cells are continuously monitored.

[0106] Through the above process, this application can flexibly select shutdown strategies and user migration schemes according to actual conditions to ensure network stability and business continuity.

[0107] Optionally, after migrating users from the target cell to the neighboring cell and selecting the second-level shutdown, provided that the first service guarantee requirement is met, the method further includes:

[0108] After entering the second-level shutdown, it is obtained whether the real-time access users of the adjacent cells meet the second service guarantee requirements;

[0109] If the second service guarantee requirement is not met, the second-level shutdown will be exited, and the target user in the adjacent cell will be migrated to the target cell.

[0110] If the second business assurance requirement is met, the second evaluation cycle will begin.

[0111] If the second evaluation cycle begins and continues for a preset duration, and the second current network load is less than the second threshold value, then the minute-level shutdown is selected.

[0112] In this embodiment, under the condition of meeting the first service guarantee requirement, users of the target cell have been migrated to neighboring cells, and a second-level shutdown has been selected. After entering the second-level shutdown state, the real-time access user status of neighboring cells within the second evaluation period is acquired. Whether these real-time access users meet the second service guarantee requirement (e.g., including but not limited to key indicators such as the number of large packet users, perceived speed, and service quality) is evaluated. If the real-time access users of neighboring cells do not meet the second service guarantee requirement, it indicates that the current second-level shutdown state has a significant impact on neighboring cells and requires immediate adjustment. Target users in neighboring cells (target users can refer to users previously migrated from the target cell, or large packet users in neighboring cells) are migrated back to the target cell to ensure that the service guarantee requirement is met. If the real-time access users of neighboring cells meet the second service guarantee requirement, it indicates that the impact of the second-level shutdown on neighboring cells is within an acceptable range, and the next evaluation step is performed.

[0113] It should be noted that the second evaluation cycle is in seconds, while the first evaluation cycle is in minutes.

[0114] If the first assessment cycle begins, the preset duration will continue for at least two second-level assessment cycles. Within this preset duration, the load status and service assurance requirements of neighboring and target cells will continue to be monitored. If the second current network load (i.e., the total load of neighboring and target cells) remains below the second threshold, it indicates that the current network load is low and the impact of the second-level shutdown on neighboring cells has stabilized, allowing for further energy consumption reduction. In this case, a minute-level shutdown will be initiated to further save energy and reduce operating costs.

[0115] Optionally, after selecting the minute-level shutdown, the method further includes:

[0116] After selecting the minute-level shutdown, the third current network load status of the adjacent cells is determined based on the third evaluation period;

[0117] When the third network load condition is greater than or equal to the third threshold value, control the neighboring cells to interact with the target cell, execute the target cell wake-up process and exit the minute-level shutdown process;

[0118] If the third current network load condition is less than the third threshold value, the step of determining the third current network load condition of the neighboring cells based on the third evaluation period continues.

[0119] Optionally, both the third and first evaluation cycles are in the minute range, with the third evaluation cycle being longer than the first evaluation cycle.

[0120] In this embodiment, by introducing a second service assurance requirement and second and third evaluation cycles, the monitoring and evaluation of the impact on services in adjacent cells after a second-level shutdown are increased, ensuring that user migration and shutdown operations will not cause unacceptable impacts on adjacent cells. Through continuous monitoring and evaluation, the shutdown strategy can be dynamically adjusted according to the actual situation, ensuring both the satisfaction of service assurance requirements and improving energy utilization efficiency. This application utilizes a gradual shutdown, starting with a second-level shutdown and gradually transitioning to a minute-level shutdown, to ensure network stability and user experience.

[0121] In this embodiment, after selecting minute-level shutdown, neighboring cell load monitoring and shutdown adjustment are based on minute-level assessment. Specifically: after selecting minute-level shutdown, the third current network load of neighboring cells is continuously monitored based on the third assessment cycle. If the third current network load is greater than or equal to a preset third threshold, it indicates that the load of the neighboring cell is already high, and the target cell may need to provide additional capacity support. At this time, the neighboring cell is controlled to interact with the target cell, execute the wake-up process of the target cell, and exit the minute-level shutdown state to ensure network stability and user experience. If the third current network load is less than the third threshold, it indicates that the load of the neighboring cell is still low, and the third assessment cycle can continue to be executed to maintain the current shutdown state, in order to further save energy and reduce operating costs. This process ensures that the network can dynamically adjust the shutdown strategy according to the load while saving energy, thus guaranteeing user experience and network stability.

[0122] In another specific embodiment, refer to Figure 3 The diagram shown illustrates the shutdown operation principle of the communication module structure. The AAU uses... Figure 3 Taking the optical module shown as an example, and, with Figure 4 The diagram showing the switching between second-level and minute-level workflows illustrates the specific process for selecting between second-level and minute-level shutdown.

[0123] Step 1: Assess the first current network load of the target cell within the first assessment period T1 (e.g., load rate, number of users). In low-service or no-service scenarios, initiate the first assessment period T1 for the target cell's load, and continuously monitor the target cell's load during this period.

[0124] Step 2: Compare the current network load of the target cell with a preset first threshold. If the load of the target cell is lower than the first threshold, communicate with neighboring cells to obtain their load information. Calculate the total current network load of the target cell and neighboring cells.

[0125] Step 3: Determine whether the target cell meets the primary service guarantee requirements.

[0126] Step 4: If the first service guarantee requirement is met, migrate users from the target cell to an adjacent cell, and the target cell will be shut down within seconds. If the service guarantee requirement is met, migrate users from the target cell to an adjacent cell. The target cell will enter a second-level shutdown state and initiate a second-level assessment cycle (the second-level assessment cycle here refers to the second assessment cycle T2 mentioned above). If the first service guarantee requirement is not met, reassess whether the total load of the target cell is below the first threshold.

[0127] Step 4: Within the second evaluation period T2, based on whether the real-time access users of the neighboring cell network meet the second service guarantee requirements (such as the number of large packet users, perceived speed, etc.), determine whether the target cell needs to be shut down. If the second service guarantee requirements are not met, execute the shutdown procedure for the target cell and migrate the large packet users of the neighboring cells to the target cell to ensure user experience.

[0128] Step 5: After several seconds of continuous evaluation, if it is determined that the load of the adjacent cell is still lower than the second threshold and meets the second service guarantee requirements, the base station enters the minute-level shutdown state.

[0129] Step 7: After entering the minute-level shutdown, initiate the minute-level evaluation cycle (here, the minute-level evaluation cycle refers to the third evaluation cycle T3 mentioned above) to evaluate based on the current network load of adjacent cells. That is, within the third evaluation cycle T3, determine whether the third current network compliance status of adjacent cells is greater than or equal to the third threshold value. If it is determined to be greater than the third threshold value, then execute the process of exiting the minute-level shutdown for the target cell.

[0130] In summary, the service-adaptive intelligent base station shutdown strategy proposed in this application has several significant advantages over existing technologies, mainly reflected in the following aspects:

[0131] (1) Significantly improved energy saving effect: Extreme superposition of time slot level energy saving: Time slot level shutdown breaks with tradition and proposes a differentiated shutdown method based on time slot level services. For the service channel, when there is no downlink data, all radio frequency channels are shut down. When there is data, the service is aggregated into a few symbols and the empty symbols are shut down. After aggregation, the resource occupancy rate is low and some radio frequency channels can be shut down. The energy saving of multiple links is superimposed, which greatly reduces power consumption.

[0132] Second-level and minute-level progressive energy saving: The second-level and minute-level shutdown adopts a service-adaptive progressive shutdown method. Based on the total load of the target cell and neighboring cells and the service guarantee requirements, it first enters the second-level shutdown and then the minute-level shutdown, gradually deepening energy saving and effectively reducing the overall energy consumption of the base station.

[0133] (2) High Adaptability and Intelligence: Time-Slot-Level Device Adaptability: In time-slot-level shutdown, differentiated processing is performed based on the different characteristics of service channels and broadcast channels. Service channels can adaptively shut down channels based on the presence or absence of data and resource occupancy. Broadcast channels can flexibly configure partial channel shutdown and power compensation, enabling base stations to adaptively adjust under different service scenarios and achieve intelligent energy saving.

[0134] Second-level and minute-level adaptive decision-making: When shutting down at the second or minute level, the base station automatically decides to enter different shutdown levels by evaluating multiple factors, and dynamically adjusts according to load and service guarantee requirements to achieve adaptive intelligent management.

[0135] (3) Strong User Experience Guarantee: Time-slot-level Service Continuity Guarantee: Time-slot-level shutdown provides fine-grained processing of service channels and broadcast channels, saving energy while ensuring normal service operation. Service channels rationally aggregate services, and broadcast channels centrally schedule services and ensure coverage, ensuring that user services are not affected.

[0136] Second-level and minute-level shutdown avoids the ping-pong effect: The second-level and minute-level shutdown adopts a gradual shutdown to avoid the ping-pong effect of base stations frequently switching between shutdown and on states, ensuring network stability and reliability, and providing users with a continuous and stable service experience.

[0137] (4) High-efficiency optimization of resource utilization: Time slot level time domain resource utilization: Time slot level shutdown of both service channels and broadcast channels focuses on making full use of time domain resources. Service channels aggregate services and shut down spare symbols, while broadcast channels centrally schedule services to common signal symbols, thereby improving the utilization rate of time domain resources.

[0138] Second-level and minute-level load balancing: Second-level and minute-level shutdowns assess the total load of the target cell and neighboring cells, rationally allocate services, avoid excessively high or low local loads, achieve load balancing between cells, and improve the overall network resource utilization efficiency.
