It should be noted that fig. 1 only shows one possible system structure to which the embodiment of the present application can be applied, and when the embodiment of the present application is implemented specifically, the system structure may also be adjusted according to practical situations, and the present application may not be limited thereto.

Fig. 2 is a flowchart illustrating a method for saving power of a base station according to an exemplary embodiment, and as shown in fig. 2, the method may include steps 21 to 22.

Step 21, the base station energy saving device obtains service connection information of at least one terminal in a preset time period of a target area.

The service connection information comprises a service type, a service occurrence period and service information.

In an implementable manner, the base station energy saving device obtains service connection information of the terminal within a preset time period of the target area. The preset time interval is set according to the service scene and the terminal type in the target area. Illustratively, the predetermined period of time is 15-60 days.

The service type in the service connection information may be obtained by each terminal following the uplink signaling message, or may be obtained by the base station energy saving device through an International Mobile Subscriber Identity (IMSI) number segment of the terminal number card. Specifically, the service types are classified into three types: non-real time traffic, fixed time period traffic, and real time traffic.

The real-time performance of the non-real-time service is not strong, if the corresponding base station is closed, the service can be performed when the corresponding base station is started, and the user experience cannot be influenced. Illustratively, such as meter reading services (water meters, gas meters, etc.).

The fixed time period service is carried out in a fixed time period every day, no service is generated in other time periods generally, and the base station is closed in the time period without the service generation, so that no influence is caused on the service. For example, smart street lamps, smart parking, etc.

Real-time traffic may occur at any time, and when traffic occurs, it is required to establish a connection in real time for data transmission, and if traffic occurs but the connection cannot be established, the user experience will be affected, and economic loss may occur. Exemplary, such as smart door locks, shared bicycles, smart fire fighting, etc.

Optionally, the service type further includes a service subclass, such as: intelligent street lamp of fixed period business etc..

The traffic occurrence period includes a start time and an end time for making a traffic connection. The start time is related to the cause value (e.g., mo-Data or mt-Access, etc.). The ending time is the RRC release time corresponding to the service connection request meeting the judgment condition. The purpose of determining the traffic occurrence period here is to remove traffic-independent connection set-ups.

The service information includes the number of connections of at least one terminal in a preset time period, a measurement report list, and the like. The measurement report list comprises at least one measurement report, the measurement report is reported by each terminal in a service connection state, all the measurement reports are distinguished according to terminal identifiers, then the measurement reports are sequenced in a sharing mode, and finally the measurement report list is generated.

For example, the obtained service type and the service occurrence period are detailed in table 1.

TABLE 1

And step 22, the base station energy-saving device determines the starting information corresponding to at least one terminal according to the service type, the service occurrence time period and the service information.

Wherein the opening information comprises an opening time interval and an opening cell.

In an implementable manner, the base station energy saving device designs an energy saving scheme adapted to each terminal according to the service type, the service occurrence period and the service information, and opens the corresponding opening cell in the opening period according to the energy saving scheme, so that not only can service be provided for each terminal, but also energy can be saved.

Exemplary, the opening information is detailed in table 2.

TABLE 2

Period of opening	Opening a cell
		……	……

Optionally, with reference to fig. 2, as shown in fig. 3, step 22 further includes the following sub-steps:

step 221a, when the service type of the target terminal is a non-real-time service, the base station energy saving device obtains a first starting time period and a first starting time according to the service occurrence time period and the connection times of the target terminal in the service information in a preset time period.

Wherein the target terminal belongs to at least one terminal.

In an implementable manner, when the service type of the target terminal is a non-real-time service, the base station energy saving device performs calculation according to the service occurrence period and the connection times of the target terminal in the service information in a preset time period, and determines a first starting period. The service occurrence time interval is the starting time and the ending time of each service provision of a first starting cell providing services for a target terminal in a target area. The connection times of the target terminal in the preset time period are the times of establishing service connection in the preset time period by the first starting cell in the target area.

Illustratively, the base station energy saving device determines that the cell a serves the target terminal, and then turns on the cell a according to the first turn-on period of the cell a.

For cell a, the on period is determined in the following manner: and counting the times of providing services for the cell A every day in a preset period, and selecting the day with the most services as a calculation basis. Wherein the first on period (T1) satisfies the following formula:

T1＝(t1+t2+……tn)×α/(Nrrc×3600)

where Nrrc is the number of RRC connections that can be simultaneously established by cell a, t1 is the duration of service 1 (i.e., the ending time of service 1 minus the starting time of service 1), t2 is the duration of service 2 (i.e., the ending time of service 1 minus the starting time of service 1), and so on, and tn is the duration of service n. Alpha is a correction coefficient, is a number larger than 1, can be a decimal number or an integer, and the correction sparse alpha is used for reserving network resources for burst services.

After the turn-on period is determined, the turn-on times need to be determined. Wherein, the opening times satisfy the following formula:

X1＝min(E(Xun),n1)

where n1 is the maximum frequency of turning on and off the base station per day. E (xun) is an average value of the number of times that all terminals in the cell a establish service connection in the day in which the cell a provides the service at most in a preset time period. The frequent switching of the base station is not beneficial to the energy conservation of the base station and the user experience. Illustratively, the value of n1 is less than or equal to 3.

In conjunction with the above result, if X1 is equal to 1, the first on period T1 consists of 1 sub-period, turned on 1 time; if X1 is equal to 2, the first on period T1 consists of 2 sub-periods, which are on 2 times; if X1 is equal to 3, the first on period T1 is composed of 3 sub-periods, which are turned on 3 times. By analogy, the number of sub-periods and the number of times of opening of the first opening period T1 may be determined.

Step 222a, the base station energy saving device determines the starting information corresponding to the target terminal.

The starting information is to start a first starting cell according to a first starting time interval and a first starting frequency, and the first starting cell belongs to a target area and provides service for a target terminal.

In an implementable manner, the base station energy saving device determines the starting information corresponding to the target terminal according to the determined first starting time period and the first starting times, and subsequently, the base station energy saving device starts the cell according to the starting information.

For example, in connection with step 221a, if the first on period T1 determined by cell a consists of 1 sub-period, then it is turned on 1 time, and it is usually selected to turn on cell a in the daily valley power utilization period (e.g. from 23: 00 in beijing), and turn on for a time period of T1; if the first on-period T1 consists of 2 sub-periods, then it is turned on 2 times, and usually it is selected to turn on cell a in the valley power consumption segment (e.g. 3: 00 in beijing area) and the flat power consumption segment (e.g. 15:00 in beijing area) and turn on T1/2 time, the two sub-periods start 12 hours apart; if the first on period T1 consists of 3 sub-periods, then it is turned on 3 times in total, and it is usually selected to turn on cell a in the valley electricity utilization period (e.g., from 23: 00 in beijing) and two flat electricity utilization periods (e.g., from 7:00 and 15:00 in beijing) and turn on T1/3 of the time period, respectively, every day.

After the T1 and the opening times are determined, the scheduling algorithm ensures that different terminals of the same service type uniformly initiate connection establishment requests at different time points in the T1 time.

Optionally, with reference to fig. 2, as shown in fig. 4, step 22 further includes the following sub-steps:

and step 221b, when the service type of the target terminal is a fixed time interval service, classifying the service occurrence time interval to obtain a second starting time interval.

Wherein the target terminal belongs to at least one terminal.

In an implementable manner, when the service type of the target terminal is a fixed-period service, the base station energy saving device classifies the service occurrence period to obtain a second start period. The service occurrence time interval is the starting time and the ending time of each service provision of a first starting cell providing services for a target terminal in a target area.

Specifically, when the service type of the target terminal is a fixed-period service, the base station energy saving device counts service occurrence periods corresponding to the target terminal, and records the service occurrence periods as T21, T22, … … T2 n. T2n may be determined according to the service subclass, such as: the street lamp service is started at 7 nights and closed at six nights every day, and the occurrence time period T2x corresponding to the street lamp service is 19:00-6: 00; t2 n; statistics can also be made by the time of occurrence of the traffic. And after the service occurrence time interval of each fixed time interval service is obtained, classifying the service from the service occurrence time interval of the first service. If the time of the service occurrence period of the first service is the same as the time of the service occurrence period of the second service, only one time period is recorded, and if the time difference between the service occurrence period of the first fixed period service and the service occurrence period of the second fixed period service is small, the starting time of the service occurrence period of the first fixed period service and the ending time of the service occurrence period of the second fixed period service are recorded. And analogizing in turn to finally obtain the statistical result of the first opening cell.

For example, T2X is set as a service occurrence period of a fixed-period service, the start time is T2xs, the end time is T2xe, and X may be 1, 2, … … n. The specific determination method comprises the following steps:

1) let T21' ═ T21;

2) judging whether T22 is present

If it is

T22' is empty, otherwise step 3 is entered;

3) judging whether T21' is present

If it is

T21 '═ T22, T22' is empty, otherwise step 4 is entered;

4) judging whether T22s is E T21 ' or T22e is E T21 ', if T22s is E T21 ' or T22e is E T21 ', then T21 ' is T21 ' U T22, and T22 ' is empty, otherwise, entering the step 5;

6) let T22' ═ T22;

7) t23 performs steps 2-5 with all non-empty subsets in the set { T2x ', starting from T21 ', in order to determine T23 ';

8) in the execution process of step 7, if it is determined that T23 'is empty, it is determined whether T2 x' is updated in the set { T2x '}, if T2 x' is updated in the set { T2x '}, step 9 is entered, otherwise, step 12 is entered, step 7 and all subsets execute step 2-step 55, and T23' is not determined yet, step 11 is entered;

9) the T2x ' performs the steps 2-5 with all non-empty subsets except the T21 ', determines whether the T2x ' is judged to be empty, if the T2x ' is judged to be empty, the T2x ' and the T2y ' are updated together to form a new T2y ', if yes, the step 10 is carried out, otherwise, the step 12 is carried out;

10) the T2y ' performs steps 2-5 with all non-empty subsets except the T21 ', determines whether T2y ' is judged to be empty, if T2y ' is judged to be empty, the T2y ' and the T2z ' are updated together to form a new T2z ', and the T2z ' performs steps 2-5 with all non-empty subsets except the T21 ', and so on until no subset is updated, and the step 12 is executed;

11)T23’＝T23；

12) t24 ', T25 ', through T2n ' were determined as described above.

In the above steps, tt is an interval time period, and when the difference between the two service occurrence time periods is less than or equal to tt, the two service occurrence time periods are combined to avoid frequently opening and closing the cell. Deleting the empty set in the set { T2x ' }, determining the empty set as a time period T2, namely, opening the first opening cell in the time period of the cell in the set { T2x ' }, if the final calculation result set { T2x ' } contains the subsets 0: 00-24: 00, indicating that the first opening cell needs to be opened in the full time period, and marking the first opening cell as a terminal containing the real-time service.

Step 222b, the base station energy saving device determines the starting information corresponding to the target terminal.

The starting information is that a first starting cell is started for the target terminal in a second starting time interval; the first open cell is a cell which belongs to the target area and provides service for the target terminal.

In an implementable manner, the base station energy saving device determines the starting information corresponding to the target terminal according to the determined second starting time period and the first starting times, and subsequently, the base station energy saving device starts the cell according to the starting information.

Further, when the service type of the target terminal is the non-real-time service and the fixed-time-period service, the base station energy saving device starts the first start cell according to the second start time period, and the method for determining the second start time period refers to steps 221b to 222 b.

Optionally, with reference to fig. 2, as shown in fig. 5, step 22 further includes the following sub-steps:

step 221c, when the service type of the target terminal is real-time service, processing the measurement report list in the service information to generate effective coverage cell data.

The effective coverage cell data includes a list of service terminals of the effective coverage cell and a list of the effective coverage cells. The target terminal belongs to at least one terminal.

Specifically, the measurement report list in the service information includes at least one measurement report reported by at least one terminal in the third opening period, all the measurement reports are distinguished according to the terminal identifiers, and then are sorted in a sharing manner, and finally the measurement report list is generated.

As shown in table 3, the measurement report includes an identity (IMEI) of the terminal, a serving cell identity, a serving cell signal quality, a serving cell signal-to-noise ratio, a neighbor cell identity, a neighbor cell quality, and a neighbor cell signal-to-noise ratio; if the inter-system neighbor exists, the inter-system neighbor also includes inter-system neighbor identifiers, inter-system signal quality, inter-system signal-to-noise ratio, and the like (the inter-system is not belonging to a 5G system, such as a 4G system, a 3G system, and the like).

TABLE 3

In an implementable manner, the base station energy saving device processes the measurement report list in the service information, and the specific processing manner is to analyze data in the test report, obtain the quality good point ratios of all the serving cells and the neighboring cells involved in each service connection state, respectively judge whether the quality good point ratio of each serving cell and the neighboring cell is greater than or equal to a third threshold, determine that the serving cell or the neighboring cell belongs to an effective coverage cell under the condition that the third threshold is met, count all the effective coverage cells, and generate an effective coverage cell list.

Illustratively, according to the measurement report list, when the terminal identified as XX0(XX0 is merely an example, and the terminal identification number is actually 15-17 bits) is in a first service connection state, the reported serving cell includes a serving cell a and a serving cell B, the reported neighboring cell includes a neighboring cell C, and the reported neighboring cell of the different system includes a neighboring cell D of the different system.

For cell a, the quality good point ratio of cell a is calculated in a manner that satisfies the following formula:

R＝Sm/St

wherein, St is the total number of measurement reports obtained by the XX0 terminal in the first service connection state; sm is the sum of the number of measurement reports which satisfy the preset condition simultaneously in all the measurement reports acquired by the XX0 terminal in the first service connection state. The preset condition is that the cell A (both adjacent cells or serving cells) is included and the signal quality of the cell A is greater than or equal to a first preset threshold; and the signal-to-noise ratio of the cell A is greater than or equal to a second preset threshold.

And obtaining an R value (the quality good point proportion of the cell A) through the formula, if the R is greater than or equal to a third threshold value, determining that the cell A is an effective coverage cell of a 001 terminal in a first connection state, and adding one to the number of the service terminals of the cell A.

By combining the above calculation modes, calculating R values of a cell B, a cell C and a cell D related to the XX0 terminal in the first service connection state respectively, then determining whether the cell B, the cell C and the cell D are effective coverage cells of the XX0 terminal in the first connection state, if the R values of the cell B, the cell C and the cell D meet requirements, the cell B, the cell C and the cell D are also effective coverage cells of the XX0 terminal in the first connection state, and meanwhile, the number of service terminals of the cell B, the cell C and the cell D is respectively increased by one; if the requirement is not met, the cell which does not meet the requirement is not an effective coverage cell of the XX0 terminal in the first connection state, and meanwhile, the number of the service terminals corresponding to the cell which does not meet the requirement is not accumulated. And then according to all the test reports obtained by the XX0 terminal in the second service connection state, counting the number of the effective coverage cells and the service terminals of the cells of the XX0 terminal in the second service connection state. And repeating the steps until statistics of all service connection state measurement reports of the XXX terminal is completed. And then, counting all service connection state measurement reports of the terminal to complete the determination of the effective coverage cell of the terminal in each connection state and the determination of the number of the service terminals in the effective coverage cell. The effective coverage cell and the number of the effective coverage cell service terminals are characterized by an effective coverage cell list and a list of the number of the effective coverage cell service terminals in the effective coverage cell data.

As shown in table 4, is a list of valid coverage cells; for XX0 terminals, the effective coverage cells with connection state numbers XX0-001 are XXX01 and XXX 02; for XX0 terminals, the effective coverage cell with connection state numbers XX0-002 is XXX 01.

TABLE 4

As shown in table 5, is a list of the number of serving terminals that effectively cover a cell. The list of the number of serving terminals that effectively covers a cell contains a total of N pieces of data. The number of terminals served by the cell with the cell identifier XXX09 is the largest, and is 799; the cell service terminal with the cell identifier XXX23 is 797 times for a plurality of times; the number of cell service terminals with cell identity XXX03 is the minimum, 10.

Step 222c, the base station energy saving device performs screening processing and deleting processing on the effective coverage cell list based on the service terminal number list of the effective coverage cell to obtain a second starting cell.

In an implementable manner, the base station energy saving device screens the effective coverage cell list, classifies the screened data into the second open cell according to the screened data, deletes the screened data in the effective coverage cell list, repeats the screening and the deletion until the effective coverage cell list is completely deleted, the data in the second open cell is complete second open cell data, and finally opens the second open cell in a third open period to provide service for the terminal.

Illustratively, the base station energy saving device generates the second starting cell according to the list of the effective coverage cells and the list of the number of the service terminals of the effective coverage cells. The method can be realized by the following steps:

step 1, screening terminals with the number of effective coverage cells of 1, listing the cells corresponding to the part of terminals into a second starting cell, because the service connection of the part of terminals can only pass through the effective coverage cells, and then deleting the data of the part of terminals from the effective coverage cell list.

And 2, deleting the data corresponding to the terminal which belongs to the second starting cell from the effective coverage cell list.

Step 3, counting the number of the service terminals of other rest cells in the effective coverage cell list: the initial value of the number of the service terminals of each cell is 0, counting is carried out from the first row of an effective coverage cell list, the total number of times of occurrence of each cell in the effective coverage cell list is the number of the service terminals of the cell, the number of the service terminals of each cell is arranged in a descending order, the cells arranged in the first cell are listed into the second starting cell, and if the number of the service terminals of a plurality of cells is the same, one cell is randomly selected and listed into the second starting cell.

And 4, deleting the data of the terminal corresponding to the cell in the second starting cell in the effective coverage cell list.

And 5, counting the service terminals of other rest cells in the effective cell coverage list, arranging the service terminals of each cell in a descending order, listing the first cell in a second starting cell, and randomly selecting one cell to be listed in the second starting cell if a plurality of cells have the same service terminals.

And 6, repeating the steps 2 to 5 until the list of the effective coverage cells is empty, and forming a final second opening cell.

And when the service type of the target terminal is real-time service and the cell of the target terminal belongs to the second open cell, the cell of the target terminal is kept open all day long, and when the cell does not belong to the second open cell list, the cell of the target terminal is closed only in the third open time period, so that the energy conservation of the base station is realized.

And step 223c, the base station energy saving device determines the starting information corresponding to the target terminal.

Wherein, the opening information is:

if the cell providing service for the target terminal belongs to the second starting cell, the cell providing service for the target terminal is started all the time;

and if the cell providing service for the target terminal does not belong to the second starting cell, starting the cell providing service for the target terminal outside the third starting time period, wherein the cell providing service for the target terminal is the cell in the target region.

In an implementable manner, the base station energy saving device determines the start information corresponding to the target terminal according to the determined second start cell, and subsequently, the base station energy saving device starts the cell according to the start information.

Illustratively, a cell a provides a cell serving a target terminal, and if the cell a belongs to a second starting cell, the cell a is started all day long; if the cell A does not belong to the second open cell, the cell A is closed in the third open period (night period), and the cell A is opened in other periods.

According to the base station energy saving method, the service connection information of at least one terminal in the preset time period of the target area is obtained, the at least one terminal is classified according to the service type in the service connection information, and the starting information corresponding to the at least one terminal is determined according to different categories. Compared with the mode of always starting the base station in the prior art, the base station is started according to the starting information corresponding to the service type, the service time and the service frequency of the base station are reduced to a certain extent, and therefore the energy conservation of the base station is achieved. Meanwhile, the method is simple and easy to operate, low in learning cost and wide in applicability.
