The power consumption of communication has a great impact on the electricity expenditure of operators. According to statistics, the annual electricity bill of operators reaches tens of billions, and the power consumption of communication base stations accounts for about 6% of the total electricity consumption in the society, which means there is a lot of room for energy saving.

The energy-saving plan is mainly formulated considering the business model between adjacent stations; and the regional scenarios with obvious business tidal effects are slow to respond to instantaneous changes in tidal scenarios, and cannot identify and implement more fine-grained energy-saving strategies, which makes the energy-saving strategy of tidal service cells insufficiently flexible and adaptable.

[0036] like Figure 1 As shown, this embodiment provides an energy saving method for a tidal service cell.

[0037] In this embodiment, the energy-saving method of the tidal service cell is applied to large venues. Large venues undertake many types of activities. Taking stadiums as an example, the types of activities include but are not limited to: sports events, concerts, and various press conferences. The time of large venues undertaking activities is irregular, resulting in a tidal effect in the communication of large scenes. Therefore, the tidal service cell is used to characterize the service cell that provides communication coverage for large venues and has a tidal effect, wherein the tidal service cell includes but is not limited to 1. Each activity has different requirements for the communication service guarantee of the venue. In order to better meet the energy-saving needs and ensure user perception, the energy-saving plan should also change accordingly. Therefore, a personalized customized energy-saving plan of "one activity, one plan" is output in combination with time requirements and coverage requirements.

[0038] It should be noted that the energy-saving method of the tidal service cell is applied to communication networks, wherein the communication networks include but are not limited to: 5G (5th Generation Mobile Communication Technology, fifth generation mobile communication technology) network, 4G (4th Generation Mobile Communication Technology, fourth generation mobile communication technology) network and 6G (6th Generation Mobile Communication Technology, sixth generation mobile communication technology) network.

[0039] Energy-saving methods for tidal service cells include:

[0040] S101, obtain a first service load set, an initial service retention period, an initial transition period, an initial first cell list and an initial second cell list, wherein the first service load refers to the service load of the target cell in each time period from the end of a preset time period to the preset activity start time of the current activity, the target cell refers to a tidal service cell that provides communication coverage for the current activity, the first cell list refers to a set of tidal service cells whose service load in the activity period is greater than a first threshold, and the second cell list refers to a set of tidal service cells whose service load in the inactive period is less than a second threshold.

[0041] It should be noted that, after acquiring the first service load set, the energy saving method for the tidal service cell further includes: marking the service period to which the first service load belongs, and obtaining a service period label corresponding to the first service load.

[0042] Specifically, obtaining the initial service holding period, the initial transition period, the initial first cell list and the initial second cell list includes steps S1011 to S1015:

[0043] S1011, obtaining a second service load set, wherein the second service load refers to the service load of each tidal service cell in each time period within a preset time period.

[0044] S1012, clustering the second business load set based on a clustering algorithm to obtain a third business load set and a fourth business load set, wherein the third business load refers to the second business load that meets a high business load index, and the fourth business load refers to the second business load that meets a low business load index.

[0045] S1013, determine an initial first cell list and an initial second cell list, wherein the initial first cell list refers to a tidal service cell set to which the third service load belongs, and the initial second cell list refers to a tidal service cell set to which the fourth service load belongs.

[0046] In this embodiment, taking the preset period of 1 year as an example, the business load of each tidal service cell in the venue for 1 year at each hour and the official activity period of each tidal service cell in each activity are clustered to obtain the following: Figure 2 The initial cell list shown in FIG. 1 includes, but is not limited to, a business load KPI (Key Performance Indicator) of the business load class, and the initial cell list includes an initial first cell list (i.e. Figure 2 The cell set contained in the dotted circle), the initial second cell list (i.e. Figure 2 The cell set contained in the black circle in the figure) and the initial third cell list (i.e. Figure 2 The cell list is used to characterize the set of service cells that provide communication coverage for the venue and have a tidal effect. That is to say, the target cell is one of the cells in the cell list, that is, one of the first cell list, the second cell list and the third cell list will include the target cell. This embodiment uses a clustering algorithm to cluster the second service load set, and can quickly and effectively divide all tidal service cells in the venue into high-service cells in the active period, low-service cells in the inactive period, and normal service cells, thereby providing effective support for the subsequent rapid allocation of energy-saving strategies to the target cells, achieving more efficient resource management and optimization, and improving energy-saving effects and efficiency.

[0047] It should be noted that clustering algorithms include but are not limited to: K-Means, DBSCAN (Density-Based Spatial Clustering of Applications with Noise), GMM (Gaussian Mixture Model), AGNES (AGglomerative NESting), and DIANA (Divisive Analysis, top-down hierarchical clustering) algorithms.

[0048] S1014: Select a minimum value in the third service load set as a first threshold, and a maximum value in the fourth service load set as a second threshold.

[0049] In this embodiment, the official activity time period of each event in the venue is predetermined, but the peak of the business volume usually does not reach the preset activity start time. Therefore, after clustering the second business load set, the minimum value in the third business load set and the maximum value in the fourth business load set are respectively selected as the minimum threshold T of high business load. high1 and low traffic load maximum threshold T low1 , and then use the minimum threshold of high traffic load T high1 and low traffic load maximum threshold T low1 , respectively serving as the first threshold and the second threshold for subsequent optimization of the first cell list and the second cell list.

[0050] It should be noted that, considering the threshold of the cell's own load management and power strategy optimization, such as: the current deep sleep power saving strategy judgment threshold T low2 and the current cell expansion threshold T high2 In this embodiment, the minimum threshold T of high traffic load is high1 and low traffic load maximum threshold T low1 , which are then used as the first threshold and the second threshold of the subsequent optimization of the first cell list and the second cell list, respectively. The threshold T can also be determined based on the current deep sleep power saving strategy. low2 and the current cell expansion threshold T high2 Correct the first threshold and the second threshold, such as: T high =max[T high1 ,T high2 ], T low = min[T low1 ,T low2 ], T high and T low As the final first threshold and second threshold respectively.

[0051] S1015: Calculate an initial service holding period and an initial transition period based on all periods during which the third service load is greater than the first threshold and all periods during which the fourth service load is less than or equal to the first threshold and greater than the second threshold.

[0052] In this embodiment, after determining the first threshold and the second threshold, the third service load and the first threshold, the fourth service load and the second threshold are compared respectively to determine the initial service holding period T. s1 、T s2 and the initial transition period T t1 、T t2 , where T s1 Refers to the initial service holding period before the preset activity start time, T s2 Refers to the initial service holding period after the preset activity end time, T t1 Refers to the preset activity start time - T s1 The initial transition period before, T t2 Refers to the preset activity end time + T s2 After the initial transition period.

[0053] It should be noted that this embodiment can adopt a sliding window algorithm, an algorithm based on thresholds and state machines, and count all time periods when the third service load is greater than the first threshold, and all time periods when the fourth service load is less than or equal to the first threshold and greater than the second threshold, to obtain the initial service retention period and the initial transition period. It can also combine multiple algorithms for experiments and comparisons to find the most suitable specific algorithm.

[0054] S102, based on the first business load set, optimize the initial business holding period, the initial transition period, the initial first cell list and the initial second cell list to obtain the business period, the first cell list and the second cell list of the current activity, wherein the business period includes the business holding period and the transition period, the business holding period refers to all periods before the preset activity start time and after the preset activity end time when the business load is greater than the first threshold, and the transition period refers to all periods before the preset activity start time and after the preset activity end time when the business load is between the first threshold and the second threshold.

[0055] Optionally, the business period also includes a formal activity period and a non-activity period.

[0056] In this embodiment, according to the impact of activities on business fluctuations, the business period is divided into an activity period, a transition period, and an inactive period. The activity period includes a formal activity period and a business holding period. The formal activity period refers to the period between the preset activity start time and the preset activity end time. The business holding period is obtained by business load evaluation. Figure 3As shown, the business period can be divided into formal activity period, business maintenance period, transition period and inactive period.

[0057] It should be noted that, similarly to the activity period, which includes the formal activity period and the service retention period, the transition period includes a fixed transition period and a custom transition period, wherein the fixed transition period is obtained by evaluating the service load, and the custom transition period refers to a certain period of time before and after the formal activity period that is predetermined according to the activity requirements, during which the base station service is retained. For example, for a concert, a rehearsal time is arranged one day in advance. In this embodiment, the rehearsal time can be determined as a custom transition period to ensure the service requirements of the corresponding period.

[0058] Specifically, S102: based on the first service load set, the initial service holding period, the initial transition period, the initial first cell list and the initial second cell list are optimized to obtain the service period, the first cell list and the second cell list of the current activity, including steps S1021-S1025:

[0061] Specifically, S1022: based on the service load of the target cell during the informal activity period of the i-th historical activity, optimize the service holding period and transition period of the i-th historical activity to obtain the service holding period and transition period of the i+1-th historical activity, including: determining the optimized service holding period and optimized transition period of the i-th historical activity, wherein the optimized service holding period refers to all periods when the fifth service load is greater than the first threshold, the optimized transition period refers to all periods when the fifth service load is less than or equal to the first threshold and greater than the second threshold, and the fifth service load refers to the service load of the target cell during the informal activity period of the i-th historical activity; based on the optimized service holding period and optimized transition period of the i-th historical activity, optimize the service holding period and transition period of the i-th historical activity to obtain the service holding period and transition period of the i+1-th historical activity.

[0062] In this embodiment, Figure 4 As shown, if the current activity is the first historical activity, the initial business retention period (i.e. Figure 4 The initial service protection period in the initial transition period (i.e. Figure 4 The initial transition period length in the ) is used as the business holding period and transition period of the first historical activity; if the current activity is the X+1th historical activity, then the business load of each period of the Xth, ..., 1st historical activity is obtained (i.e. Figure 4 The current cell service load data and the current activity time label in the data are used, and according to the service load of each time period of the Xth, ..., 1st historical activities, the initial service holding period and the initial transition period are iteratively optimized to obtain the service holding period and the transition period of the X+1th, ..., 2nd historical activities, wherein X is a positive integer, for example, if X is 2, then according to the service load of each time period of the first historical activities, the initial service holding period and the initial transition period are optimized to obtain the service holding period and the transition period of the second historical activities; according to the service load of each time period of the second historical activities, the service holding period and the transition period of the second historical activities are optimized to obtain the service holding period and the transition period of the third historical activities.

Figure 5 According to the business load curves of the historical activities of the Xth period and the X-1th period, it can be seen that the business load of the historical activities of the Xth period meets the first threshold and the second threshold in advance / delay; and then by determining the optimized business holding period of the historical activities of the Xth period (i.e. Figure 5 T s1n ) and the optimization transition period and the business maintenance period of the Xth historical activity (i.e. Figure 5 T s1 ) and transition period, and based on the optimized business holding period and optimized transition period of the Xth period historical activity, optimize the business holding period and transition period of the Xth period historical activity [T s1X ,T s2X ,T t1X ,T t2X ] X, and obtain the service holding period and transition period of the X+1th historical activity.

[0066] In this embodiment, based on the service load of the target cell during the active period and the inactive period of the i-th historical activity, the first cell list and the second cell list of the i-th historical activity are optimized to obtain the first cell list and the second cell list of the i+1-th historical activity, specifically including: judging whether the service load of the target cell during the active period of the i-th historical activity is greater than the first threshold; judging whether the service load of the target cell during the inactive period of the i-th historical activity is less than or equal to the second threshold; judging whether the first cell list and the second cell list of the i-th historical activity include the target cell; in response to the first cell list of the i-th historical activity not including the target cell, and the service load of the target cell during the active period of the i-th historical activity is greater than the first threshold, adding the target cell to the first cell list of the i-th historical activity to obtain the first cell list of the i+1-th historical activity; in response to the second cell list of the i-th historical activity including the target cell, and the service load of the target cell during the inactive period of the i-th historical activity is greater than the second threshold, deleting the target cell from the second cell list of the i-th historical activity to obtain the second cell list of the i+1-th historical activity. This embodiment uses the service load of each activity period as the optimization basis for the cell list of each activity period, which can achieve reasonable and iterative optimization of the cell list and improve the accuracy and flexibility of the cell list of each activity period.

[0067] It should be noted that after determining whether the first cell list and the second cell list of the i-th historical activity include the target cell, the energy-saving method of the tidal service cell also includes: in response to the first cell list of the i-th historical activity including the target cell, determining whether the service load of the target cell during the activity period of n consecutive historical activities before the i+1-th historical activity is less than or equal to the first threshold; in response to the service load of the target cell during the activity period of n consecutive historical activities before the i+1-th historical activity is less than or equal to the first threshold, deleting the target cell from the first cell list of the i-th historical activity, and obtaining the first cell list of the i+1-th historical activity, where n includes but is not limited to 3.

[0069] After the second cell list in response to the i-th historical activity includes the target cell, the energy-saving method of the tidal service cell also includes: obtaining the business load of the relevant cell in each time period of the i-th historical activity, and judging whether there is an increase in the business load of the relevant cell in each time period of the i-th historical activity, wherein the relevant cell refers to a cell having a neighboring relationship with the target cell, and in response to the increase in the business load of the relevant cell in each time period of the i-th historical activity, deleting the relevant cell from the second cell list in the i-th historical activity.

[0070] S1024, repeat steps S1022 and S1023 until the i+1th historical activity is the current activity.

[0072] S103, based on the service period of the current activity, the first cell list and the second cell list, determine the energy saving strategy of the target cell in each period of the current activity, and execute the corresponding energy saving strategy.

[0073] Specifically, the energy-saving strategies include a soft-off energy-saving strategy, a no-energy-saving strategy, and a hard-off energy-saving strategy.

[0074] It should be noted that currently, the commonly used base station energy-saving methods include soft shutdown and hard shutdown. Soft shutdown energy-saving includes symbol shutdown, channel shutdown, and carrier frequency shutdown energy-saving means, which have little impact on business perception and fast recovery time, but have the characteristics of unsatisfactory power-saving effect; the hard shutdown energy-saving strategy refers to installing an IoT smart switch on the radio frequency side of the base station, and realizing the power-on and power-off of the base station radio frequency by remotely controlling the power on and off of the smart switch to achieve the purpose of energy saving of the base station. The power-saving effect is the best, but the business perception is significantly affected and the implementation is relatively inflexible, and the installation of a smart switch is required. Large venues have obvious business situation changes, different coverage areas, and large differences in business. Therefore, this embodiment combines the soft shutdown energy-saving strategy and the hard shutdown energy-saving strategy to try to achieve better power-saving effects while ensuring business perception.

[0075] Specifically, based on the service period of the current activity, the first cell list and the second cell list, the energy saving strategy of the target cell in each period of the current activity is determined, including steps S1031 to S1034:

[0076] S1031, respectively determine whether the first cell list and the second cell list of the current activity include the target cell.

[0077] S1032, in response to the first cell list and the second cell list of the current activity both including the target cell, determining the energy-saving strategies of the target cell during the active period, transition period and inactive period of the current activity as a non-energy-saving strategy, a soft-shutdown energy-saving strategy and a hard-shutdown energy-saving strategy in sequence, wherein the active period includes a formal activity period and a service retention period.

[0078] S1033, in response to the fact that only the first cell list of current activity includes the target cell, determining that the energy saving strategies of the target cell in the current activity period, transition period and inactive period are sequentially no energy saving strategy, soft shutdown energy saving strategy and soft shutdown energy saving strategy.

[0079] S1034, in response to the second cell list of only the current activity including the target cell, determining that the energy saving strategies of the target cell in the active period, transition period and inactive period of the current activity are the soft shutdown energy saving strategy, the soft shutdown energy saving strategy and the hard shutdown energy saving strategy in sequence.

[0080] In this embodiment, Figure 6 As shown, if the target cell has a service load greater than the first threshold during the active period of the current activity, the target cell implements a non-energy-saving strategy during the active period; if the target cell has a service load less than or equal to the first threshold during the inactive period of the current activity, or the target cell has a service load greater than the second threshold during the inactive period of the current activity, the target cell implements a hard-off energy-saving strategy during the inactive period; if the target cell has a service load less than or equal to the first threshold during the active period of the current activity, or the target cell has a service load greater than the second threshold during the inactive period of the current activity, the target cell implements a soft-off energy-saving strategy during the corresponding period when the service load is less than or equal to the first threshold, or greater than the second threshold; if the target cell is in the transition period of the current activity, the target cell implements a soft-off energy-saving strategy. Therefore, the energy-saving strategy of the target cell in each period of the current activity includes at least one of a soft-off energy-saving strategy, a non-energy-saving strategy, and a hard-off energy-saving strategy. This embodiment can quickly iterate and optimize the energy-saving strategy of each activity by iteratively optimizing the service period and cell list, improve the response speed of the tidal scene to instantaneous changes, and improve the flexibility and adaptability of the energy-saving strategy.

[0081] Optionally, after determining the energy-saving strategy of the target cell in each time period of the current activity, and before executing the corresponding energy-saving strategy, the energy-saving method of the tidal service cell further includes steps S1035 and S1036:

[0082] S1035, determining whether the energy saving strategy of the target cell in the current period of activity is a soft shutdown energy saving strategy.

[0083] S1036, in response to the energy-saving strategy of the current time period being a soft shutdown energy-saving strategy, obtain the configuration information and coverage status of the target cell in the current time period of activity, and determine the energy-saving mode corresponding to the energy-saving strategy of the current time period based on the configuration information and coverage status of the current time period, wherein the energy-saving mode includes at least one of the following: symbol shutdown, channel shutdown, and carrier shutdown.

[0084] In this embodiment, the coverage includes but is not limited to: coverage location, source logic number, RHUB (Radio Hub, wireless access center) number, RHUB location, cell name, cell CI (Cell Identity, cell identification), PRRU ID (pico base station, a miniaturized, low-power, low-power micro-cellular base station). Configuration information includes but is not limited to: number of cell channels, source carrier configuration, and frequency band information.

[0085] Based on the configuration information and coverage of the current time period, determine the energy-saving method corresponding to the energy-saving strategy of the current time period, specifically including: based on the configuration information and coverage of the current time period, determine the priority corresponding to the energy-saving strategy of the current time period, where the priority is: carrier shutdown > channel shutdown > symbol shutdown; based on the priority corresponding to the energy-saving strategy of the current time period, determine the energy-saving method corresponding to the energy-saving strategy of the current time period.

[0086] It should be noted that this embodiment can determine the energy-saving mode corresponding to the energy-saving strategy of the current time period based only on the configuration information of the current time period. For example: if the number of channels in the communication base station cell is configured as 1T1R and the carrier is configured as a single carrier, the energy-saving mode of symbol shutdown is selected; if the number of cell channels is configured as 2T2R and above and the carrier is configured as a single carrier, the energy-saving mode of symbol shutdown + channel shutdown is selected; if the number of cell channels is configured as 1T1R and the carrier is configured as multi-carrier, the energy-saving mode of symbol shutdown + carrier shutdown is selected; if the number of cell channels is configured as 2T2R and above and the carrier is configured as multi-carrier, the energy-saving mode of symbol shutdown + channel shutdown + carrier shutdown is selected. This embodiment makes full use of the details in the current configuration information and coverage situation, and then identifies and implements more fine-grained energy-saving methods, further refines energy-saving strategies, ensures the quality of wireless network coverage in key scenarios, and improves energy-saving effects, user experience, and service quality.

[0087] This embodiment can also determine the energy-saving method corresponding to the energy-saving strategy of the current time period based only on the coverage situation of the current time period. For example, the current event only requires communication coverage of the 1st and 2nd stands, and does not require communication coverage of the 3rd stands. For the 1st, 2nd and 3rd stands, energy-saving methods with different priorities can be used.

[0088] In addition, this embodiment can also obtain user feedback data and adjust the energy-saving strategy based on the user feedback data. For example, when force majeure occurs or the venue wireless network security team raises an urgent need (including emergency cancellation of activities), provide timely response and cancel the corresponding energy-saving strategy in a timely manner.

[0089] Optionally, after executing the corresponding energy-saving strategy, the energy-saving method of the tidal service cell further includes steps S1037 and S1038:

[0090] S1037, collecting base station energy consumption data of the target cell in each time period of the current activity.

[0091] S1038, based on the base station energy consumption data of the target cell in each period of the current activity, evaluate the energy-saving performance of the corresponding energy-saving strategy.

[0092] In this embodiment, according to the formula: Evaluate the energy efficiency of corresponding energy-saving strategies s av, where, E bf j is the energy consumption data of the base station in the jth period before energy saving, E af j is the energy consumption data of the base station in the jth period after energy saving, and M is the total period of this activity.

[0093] The present embodiment provides an energy-saving method for a tidal service cell, which identifies the details of real-time changes in business load, such as the business load change trend of each activity period from an inactive period to an active period, and divides each period of each activity period into a business holding period and a transition period in a more fine-grained manner based on the details of the real-time changes in the business load.
