As used in the present application description and the appended claims, unless otherwise clearly indicated by the context, the singular forms "a", "an" and "the" are intended to include the plural forms.

[0027] ​The embodiment of the present application provides a base station energy saving method, a baseband device, a radio frequency device, a base station and a storage medium. The base station energy saving method can be applied to the base station, the baseband device and the radio frequency device, so as to reduce the energy consumption of the base station and ensure the security of the base station. The baseband device can include a building baseband unit (BBU), a distributed unit (DU) and a centralized unit (CU), and the radio frequency device can include an active antenna unit (AAU) and a remote radio unit (RRU).

[0028] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0029] Please refer to Figure 1 , Figure 1 is a flowchart of a base station energy saving method provided by the embodiment of the present application.

[0030] As Figure 1 shown, the base station energy saving method includes steps S101 to S104.

[0031] Step S101, obtaining an energy saving time period of the base station.

[0032] In the embodiment of the present application, the energy saving time period of the base station is a time period in which the base station performs energy saving. The energy saving time period can be predicted in advance or set by a user according to an experience value.

[0033] In an embodiment, as Figure 2 shown, step S101 includes sub-step S1011 to sub-step S1012.

[0034] Sub-step S1011, obtaining historical load data of the base station.

[0035] Sub-step S1012, predicting the energy saving time period of the base station according to the historical load data.

[0036] In the embodiment of the present application, the historical load data includes load data of the base station in different time periods in a past period of time, the time granularity of different time periods can be the same or different, and the past period of time can be a past month, a past half month or a past week, which is not limited in the embodiment of the present application. For example, the historical load data includes load data of the base station in each hour in a past month, and the load data can include the number of users, throughput or user rate, etc. The historical load data of the base station can be used to accurately and flexibly predict the energy-saving time period of the base station, so that the start-stop operation of the base station can be performed multiple times in different time periods, and the idle time of the base station can be fully utilized. In the fragmented idle time period, the energy consumption of the base station can be maximally reduced.

[0037] In an embodiment, a load change curve of the base station is established according to the historical load data, the load change curve describes the relationship between the load of the base station and the time period; the load of the base station in each future time period in the multiple future time periods is predicted according to the load change curve; and the future time period corresponding to the load less than the preset load threshold is determined as the energy-saving time period of the base station. The load change curve describing the relationship between the load of the base station and the time period can be established by the historical load data, and the load in each future time period in the multiple future time periods can be accurately predicted by the load change curve. Thus, the future time period corresponding to the load less than the preset load threshold can be determined as the energy-saving time period of the base station, so that the energy-saving time period of the base station is predicted.

[0038] In the embodiment of the present application, the historical load data includes load of the base station in each historical time period in multiple historical time periods, and the load change curve of the base station can be obtained by fitting the load in each historical time period in the multiple historical time periods and each historical time period in the multiple historical time periods by using the least square method. The multiple future time periods can include different time periods in a future day or days, and the preset load threshold can be set based on actual conditions, which is not limited in the embodiment of the present application. For example, the load change curve of the base station can be obtained by fitting the load data of the base station in each hour in a past month and each hour in the past month by using the least square method, and then the load in each hour in a future day is predicted by using the load change curve.

[0039] In an embodiment, the historical time period corresponding to the load less than the preset load threshold is determined as a candidate time period; in the case that there are multiple candidate time periods, the multiple candidate time periods are divided into at least one candidate time period group, and there is an intersection time period between the multiple candidate time periods in one candidate time period group; a target time period group is determined from the at least one candidate time period group, and the number of candidate time periods in the target time period group is greater than or equal to a preset number threshold; and the intersection time period between the multiple candidate time periods in the target time period group is determined as the energy-saving time period of the base station. The preset number threshold can be set based on actual conditions, and the embodiment of the present application does not make specific limitations thereon. By determining the intersection time period between the multiple candidate time periods as the energy-saving time period of the base station, the prediction accuracy of the energy-saving time period can be further improved.

[0040] For example, the preset number threshold is 2, the historical load data of the past 3 days is used to predict the energy-saving time period of the base station in the future one day, the candidate time periods include 00:30-02:30 on August 1, 2022, 02:30-06:30 on August 1, 2022, 06:30-07:30 on August 1, 2022, 11:00-12:00 on August 1, 2022, 14:00-16:00 on August 1, 2022, 00:00-02:00 on August 2, 2022, 10:30-11:30 on August 2, 2022, 13:00-15:00 on August 3, 2022, there is an intersection time period of 00:30-02:00 between 00:30-02:30 on August 1, 2022 and 00:00-02:00 on August 2, 2022, there is an intersection time period of 10:30-11:00 between 11:00-12:00 on August 1, 2022 and 10:30-11:30 on August 2, 2022, and there is an intersection time period of 14:00-15:00 between 14:00-16:00 on August 1, 2022 and 13:00-15:00 on August 3, 2022, therefore, 00:30-02:00, 10:30-11:00 and 14:00-15:00 on August 4, 2022 can be determined as the energy-saving time period of the base station.

[0041] In step S102, in the case that the length of the energy-saving time period is greater than a preset length threshold, the environmental detection information of the base station and the mainboard temperature of the base station are obtained.

[0042] In the embodiment of the present application, the environmental detection information can include the temperature and humidity of the environment where the base station is located, and the mainboard temperature of the base station can include the mainboard temperature of the radio frequency device and / or the baseband device contained in the base station. The environmental detection information of the base station can be collected by an environmental sensor or obtained from a server, and the mainboard temperature of the base station can be collected by a temperature sensor arranged on the mainboard.

[0043] In an embodiment, the base station acquires location information of the base station, and sends an acquisition request of environment detection information carrying the location information to the server; the server, upon receiving the acquisition request of environment detection information, queries corresponding environment detection information based on the location information in the acquisition request, and sends the queried environment detection information to the base station; and the base station acquires the environment detection information sent by the server.

[0044] In an embodiment, the preset time length threshold is determined according to a sum of a first time length and a second time length, the first time length being a time length required for the base station to exit the sleep mode, and the second time length being a time length required for the base station to enter the sleep mode. Illustratively, the preset time length threshold is equal to the sum of the first time length and the second time length, or the preset time length threshold is greater than the sum of the first time length and the second time length. For example, the time length required for the base station to enter the sleep mode is 5 minutes, the time length required for the base station to exit the sleep mode is 3 minutes, and the preset time length threshold can be 8 minutes or 10 minutes. By determining that the time length of the energy saving time period is greater than the sum of the time length required for the base station to enter the sleep mode and the time length required for the base station to exit the sleep mode, the base station enters the sleep mode in the energy saving time period, thereby avoiding the situation that the base station has not enough time to exit the sleep mode after entering the sleep mode, and ensuring the communication function and quality of the user accessing the base station.

[0045] In step S103, the temperature change rate limit value of the base station is determined according to the environment detection information and the mainboard temperature, and the target start-stop strategy of the base station is determined according to the temperature change rate limit value.

[0046] In the embodiment of the application, the temperature change rate limit value of the base station can include the temperature change rate limit value of the mainboard of the radio frequency device and / or the baseband device contained in the base station, the temperature change rate limit value of the base station is the maximum value of the temperature change rate of the base station, and the target start-stop strategy can include the target power-down strategy and / or the target power-up strategy. In the process of powering down the modules in the base station according to the target power-down strategy, the temperature change rate of the base station is less than or equal to the temperature change rate limit value. Similarly, in the process of powering up according to the target power-up strategy, the temperature change rate of the base station is less than or equal to the temperature change rate limit value.

[0047] In an embodiment, as shown in FIG. 10, step S103 includes sub-steps S1031 to S1032. Figure 3

[0048] In sub-step S1031, the temperature difference between the environment temperature and the mainboard temperature is determined.

[0049] In sub-step S1032, the temperature change rate limit value of the base station is determined according to the temperature difference and the environment humidity.

[0050] ​In the embodiment of the present application, the temperature change rate limit value is negatively correlated with the temperature difference and the environmental humidity. The greater the temperature difference and the environmental humidity, the smaller the temperature change rate limit value of the base station. The smaller the temperature difference and the environmental humidity, the greater the temperature change rate limit value of the base station. The temperature change rate limit value of the base station can be adaptively determined according to the temperature difference between the environmental temperature and the mainboard temperature and the environmental humidity, so that the temperature change rate of the base station during entering or exiting the sleep mode is less than or equal to the temperature change rate limit value, thereby ensuring the safety of the base station.

[0051] In an embodiment, the temperature change rate limit value of the base station can be determined according to the temperature difference and the environmental humidity in the following manner: a first mapping relationship table is obtained, the first mapping relationship table being used to describe the corresponding relationship among the temperature difference, the environmental humidity and the temperature change rate; the first mapping relationship table is queried to obtain the temperature change rate corresponding to the temperature difference and the environmental humidity, and the obtained temperature change rate is determined as the temperature change rate limit value of the base station. The corresponding relationship among the temperature difference, the environmental humidity and the temperature change rate can be set based on actual conditions, and the embodiment of the present application does not make a specific limitation thereon.

[0052] In an embodiment, the first preset temperature change rate is determined as the temperature change rate limit value of the base station when the temperature difference is less than or equal to a first preset temperature difference and the environmental humidity is less than or equal to a first preset humidity. When the temperature difference is small and the environmental humidity is low, it is determined that the base station will not have a reliability risk such as condensation, and therefore the temperature change rate limit value of the base station can be set to be large, so that the base station can complete the power down or power up of the module in a short time, thereby enabling the base station to quickly enter or exit the sleep mode.

[0053] In an embodiment, the second preset temperature change rate is determined as the temperature change rate limit value of the base station when the temperature difference is greater than a second preset temperature difference and the environmental humidity is greater than a second preset humidity. The first preset temperature change rate is greater than the second preset temperature change rate. When the temperature difference is large and the environmental humidity is high, it is determined that the base station can have a reliability risk such as condensation, and therefore the temperature change rate limit value of the base station can be set to be small, so that the temperature of the base station can be slowly decreased when the module is powered down and / or powered up, thereby avoiding the reliability risk such as condensation and ensuring the safety of the base station.

[0054] In an embodiment, when the temperature difference is greater than the first preset temperature difference and less than the second preset temperature difference, and the ambient humidity is greater than the first preset humidity and less than or equal to the second preset humidity, the third preset temperature change rate is determined as the temperature change rate limit of the base station. The third preset temperature change rate is less than the first preset temperature change rate, and the third preset temperature change rate is greater than the second preset temperature change rate. By determining that the base station will not have reliability risks such as condensation when the temperature difference is small and the ambient humidity is low, the temperature change rate limit of the base station can be set to be larger, so that the base station can complete the power down or power up of the module in a shorter time, so that the base station can quickly enter or exit the sleep mode.

[0055] In the embodiment of the application, the first preset temperature difference is less than or equal to the second preset temperature difference, the first preset humidity is less than or equal to the second preset humidity, and the first preset temperature difference, the first preset humidity, the second preset temperature difference, the second preset humidity, the first preset temperature change rate and the second preset temperature change rate can be set based on actual conditions, which are not specifically limited in the embodiment of the application.

[0056] In an embodiment, according to the temperature change rate limit, the target start-stop strategy of the base station can be determined in the following manner: a target temperature change curve is obtained according to the temperature change rate limit, the maximum temperature change rate of the target temperature change curve is less than or equal to the temperature change rate limit; a start-stop strategy corresponding to the target temperature change curve is obtained, and the start-stop strategy corresponding to the target temperature change curve is determined as the target start-stop strategy. In the process of executing the target start-stop strategy, the temperature change curve of the base station is the same as the target temperature change curve. Since the maximum temperature change rate of the target temperature change curve is less than or equal to the temperature change rate limit, and the temperature change curve of the base station is the same as the target temperature change curve in the process of executing the target start-stop strategy, it can be ensured that the temperature change rate of the base station is less than or equal to the temperature change rate limit in the process of powering down and / or powering up the internal modules of the base station, so as to ensure the safety of the base station.

[0057] In an embodiment, the target start-stop strategy includes a target power down strategy and / or a target power up strategy, and in the process of executing the target start-stop strategy, the temperature change curve of the base station is the same as the target temperature change curve, including that in the process of powering down each module in the base station according to the target power down strategy, the temperature change rate of the base station is less than or equal to the temperature change rate limit, and / or in the process of powering up the modules in the base station in sleep according to the target power up strategy, the temperature change rate of the base station is less than or equal to the temperature change rate limit.

[0058] In an embodiment, according to the temperature change rate limit value, the target temperature change curve can be obtained in the following manner: obtaining a maximum temperature change rate of each preset temperature change curve in the plurality of preset temperature change curves, and determining the preset temperature change curve with the maximum temperature change rate less than or equal to the temperature change rate limit value as the target temperature change curve. By determining the preset temperature change curve with the maximum temperature change rate less than or equal to the temperature change rate limit value as the target temperature change curve, it can be ensured that the temperature change rate of the base station is less than or equal to the temperature change rate limit value during the process of powering down and / or powering up the modules inside the base station, so as to ensure the safety of the base station.

[0059] In an embodiment, the target temperature change curve corresponds to a start-stop strategy, and the target start-stop strategy of the base station can be obtained in the following manner: obtaining a second mapping relationship table, the second mapping relationship table describing the corresponding relationship between the temperature change curve and the start-stop strategy; and querying the second mapping relationship table to obtain the start-stop strategy corresponding to the target temperature change curve. The corresponding relationship between the temperature change curve and the start-stop strategy can be set based on actual conditions, and the embodiments of the present application do not make specific limitations thereto.

[0060] In an embodiment, the target temperature change curve corresponds to a start-stop strategy, and the target start-stop strategy of the base station can be obtained in the following manner: obtaining a second mapping relationship table, the second mapping relationship table describing the corresponding relationship between the temperature change curve and the start-stop strategy; and querying the second mapping relationship table to obtain the start-stop strategy corresponding to the target temperature change curve. The corresponding relationship between the temperature change curve and the start-stop strategy can be set based on actual conditions, and the embodiments of the present application do not make specific limitations thereto.

[0061] In step S104, the target start-stop strategy is executed in the energy-saving time period, so that the base station is in the sleep mode in the energy-saving time period and the base station exits the sleep mode after the energy-saving time period.

[0062] In the embodiments of the present application, in the process of executing the target start-stop strategy, the temperature change rate of the base station is less than or equal to the temperature change rate limit value, the target start-stop strategy includes a target power-down strategy and / or a target power-up strategy, and in the process of executing the target start-stop strategy, the temperature change rate of the base station is less than or equal to the temperature change rate limit value, including that in the process of powering down each module in the base station according to the target power-down strategy, the temperature change rate of the base station is less than or equal to the temperature change rate limit value, and / or in the process of powering up each module in the base station in sleep according to the target power-up strategy, the temperature change rate of the base station is less than or equal to the temperature change rate limit value.

[0063] In an embodiment, the target power-off strategy comprises a power-off sequence of the modules in the base station and a power-off interval time of the modules, and the target power-on strategy comprises a power-on sequence of the dormant modules in the base station and a power-on interval time of the dormant modules. The power-off interval time or the power-on interval time of the modules can also be zero, that is, the modules in the base station can be powered off or powered on at the same time, or the modules in the base station can be powered off or powered on in batches. It can be understood that, in the case of a large temperature change rate limit value, the power-off interval time of the modules in the base station and / or the power-on interval time of the dormant modules is short, so that the base station can quickly enter the sleep mode or exit the sleep mode, and in the case of a small temperature change rate limit value, the power-off interval time of the modules in the base station and / or the power-on interval time of the dormant modules is long, so that the temperature of the base station can be slowly reduced during the process of powering off or powering on the modules, to ensure the safety of the base station.

[0064] In an embodiment, as shown in FIG. 10, step S104 can comprise sub-step S1041 to sub-step S1042. Figure 4

[0065] Sub-step S1041, in the case where the current system time of the base station reaches the start time of the energy-saving time period, powering off the modules in the base station according to the target power-off strategy, so that the base station is in the sleep mode.

[0066] Sub-step S1042, obtaining the sleep duration of the base station and the first time duration, determining the difference between the sleep duration and the end time of the energy-saving time period, to obtain the remaining sleep duration.

[0067] Sub-step S1043, in the case where the difference between the remaining sleep duration and the first time duration is within a preset difference range, powering on the dormant modules in the base station, or powering on the dormant modules in the base station according to the target power-on strategy, so that the base station exits the sleep mode after the energy-saving time period.

[0068] In the embodiment of the application, in the case where the current system time of the base station reaches the start time of the energy-saving time period, the modules in the base station are powered off according to the target power-off strategy, so that the base station is in the sleep mode, and then in the case where the difference between the remaining sleep duration of the base station and the first time duration is within a preset difference range, the dormant modules in the base station are powered on, so that the base station exits the sleep mode after the energy-saving time period, thereby providing communication services for users.

[0069] ​It can be understood that the preset difference range can be set based on actual conditions, and embodiments of the present application do not make specific limitations. For example, the preset difference range is [0, 2] minutes, the first time length is 3 minutes, the remaining sleep time length of the base station is 10 minutes, the difference between the remaining sleep time length of the base station and the first time length is 7 minutes, which is not located in [0, 2] minutes, and the base station continues to be in the sleep mode. In the case that the remaining sleep time length of the base station is 3 minutes, the difference between the remaining sleep time length of the base station and the first time length is 0 minutes, which is located in [0, 2] minutes, so the base station starts to power up the sleep module in the base station at this time, so that after 3 minutes, the base station exits the sleep mode.

In the case that the base station is in the sleep mode, all the modules contained in the radio frequency device are in the power-off state except the start-stop control unit which is in the running state, which can greatly reduce the energy consumption of the radio frequency device, so that the energy consumption of the radio frequency device can be reduced to tens of watts or even a few watts.

By migrating the user terminals accessing the base station to the base stations adjacent to the base station and then executing the target start-stop strategy in the energy-saving time period, the communication quality of the user terminals can be ensured, and the energy consumption of the base station can be reduced.

[0076] The base station energy saving method provided by the above embodiment determines the temperature change rate limit value of the base station according to the environmental detection information of the base station and the mainboard temperature of the base station in the case that the length of the energy saving time period of the base station is greater than the preset length threshold, and determines the target start-stop strategy of the base station according to the temperature change rate limit value, so that the target start-stop strategy is executed in the energy saving time period of the base station, so that the base station is in the sleep mode in the energy saving time period and the base station exits the sleep mode after the energy saving time period, thereby reducing the energy consumption of the base station, and since the temperature change rate of the base station is less than or equal to the temperature change rate limit value in the process of executing the target start-stop strategy, the devices in the base station will not be damaged due to too fast temperature change, and the condensation and other phenomena of the base station due to too fast temperature change can also be avoided, thereby greatly improving the safety of the base station and realizing the reduction of the energy consumption of the base station while ensuring the safety of the base station.
