Description

Base station energy saving method, device, equipment and storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method, an apparatus, a device, and a storage medium for saving energy for a base station.

Background

Energy saving can be achieved in two ways when the service is idle (e.g. at night). The first mode is to turn off the 5G cell, turn on the 4G cell, and provide coverage through the 4G cell; the second way is to switch off part of the 5G cells, providing coverage through the remaining 5G cells.

For the first mode, the 5G cell is closed, so that energy saving can be realized; however, the use of the 4G base station for coverage will affect the user experience; for the second mode, since the coverage of the 5G cell is better when the service is idle than when the service is busy, the compensation coverage can be implemented between the 5G cells; energy saving can be achieved by switching off part of the 5G cells, but if there are still a few users in an individual cell, the 5G cells also need to be switched on. Thus, energy is wasted.

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 23:

and step 21, the base station energy-saving device acquires a measurement report list in a preset time period of a target area. The measurement report list comprises at least one measurement report, and the measurement report is reported by at least one terminal in a service connection state.

In an implementable manner, a preset time period is set according to a service scene and a terminal type in a target area; the measurement report list comprises at least one measurement report reported by at least one terminal. All the measurement reports are distinguished according to the terminal identification, then sorted in a copy-by-copy manner, and finally a measurement report list is generated. The measurement report is reported when all terminals in the target area perform service connection within a preset time period.

For one terminal, multiple measurement reports can be generated in one traffic connection state. The number of measurement reports generated is related to the duration of the traffic connection state. For example, it is set that one measurement report is generated every 200ms, and in a traffic connection state of 1 minute, terminal a reports 5 measurement reports. Assuming that each row in the measurement report list represents a measurement report reported by the terminal in the service connection state, for the terminal a, the measurement report reported by the terminal a will occupy 5 rows in the measurement report list.

Illustratively, the predetermined period of time is 15-60 days. As shown in table 1, the measurement report reported by the terminal includes an identifier (IMEI) of the terminal, an identifier of a serving cell, signal quality of the serving cell, signal-to-noise ratio of the serving cell, an identifier of a neighboring cell, quality of the neighboring cell, and signal-to-noise ratio of the neighboring cell; if the inter-system neighbor exists, the inter-system neighbor also includes inter-system neighbor identification, 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), and all the information forms a measurement report.

After the base station acquires the measurement report reported by the terminal, the base station respectively calculates the number of service connection times of each terminal in a preset time period and the number of measurement reports in the average service connection state of each time, and lays a cushion for subsequently determining the opened cell.

TABLE 1

And step 22, the base station energy-saving device screens the measurement reports in the measurement report list based on a preset rule to obtain a target measurement report list.

Wherein the target measurement report list comprises each measurement report meeting the screening requirement.

In an implementation manner, since the measurement report includes the occasionally-connected terminal, if the occasionally-connected data is treated as the standard data, the base station energy saving device may also provide coverage for the data, thereby causing resource waste. Therefore, the base station screens the measurement reports in the measurement report list based on a preset rule, and deletes some test reports corresponding to the terminals which occur occasionally.

Further, the preset rule is a measurement report corresponding to a terminal for which the service connection frequency is determined to be less than or equal to a first preset threshold.

In an implementation manner, if the number of service connections corresponding to the terminal is less than or equal to a first preset threshold, it indicates that the terminal is only occasionally present in the target area, and a fixed user that does not belong to the target area belongs to an interference factor, and the interference factor needs to be deleted. Wherein, the first preset threshold is a natural number. For example, the first preset threshold may be 1.

And step 23, the base station energy-saving device performs data processing on the target measurement report list to obtain an open cell list.

The cell list is opened to cells which can meet coverage requirements within a preset time period of a target area.

Further, referring to fig. 2, as shown in fig. 3, step 23 includes the following sub-steps:

step 231, the base station energy saving device processes the cell information of at least one terminal in the target measurement report list in the service connection state to obtain an effective serving cell list and a serving terminal number list of the effective serving cell list.

Step 231 corresponds to step a.

The cell information comprises service cell information, neighbor cell information and inter-system neighbor cell information, and the effective service cell list comprises an effective service cell list and an inter-system service cell list.

In an implementation manner, taking a terminal as an example, a measurement report of the terminal in a service connection state each time is obtained from a target measurement report list, so as to obtain quality good point ratios of all serving cells and neighboring cells involved in the service connection state each time, respectively determine whether the quality good point ratio of each serving cell and neighboring cell is greater than or equal to a fourth preset threshold, determine that the serving cell or neighboring cell belongs to an effective coverage cell if the quality good point ratio of each serving cell and neighboring cell meets the fourth preset threshold, count all effective coverage cells, and generate a first effective coverage cell.

Illustratively, according to the target 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 neighbor cells and serving cells) is included; the signal quality of the cell A is greater than or equal to a second preset threshold; and the signal-to-noise ratio of the cell A is greater than or equal to a third preset threshold.

And obtaining an R value (the quality good point proportion of the serving cell A) through the formula, and if the R value is greater than or equal to a fourth 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 serving terminals of the cell A.

By combining the above calculation modes, calculating R values of a XX0 terminal in a first service connection state and related to a cell B, a cell C and a cell D, and then determining whether the cell B, the cell C and the cell D are effective coverage cells of an 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 an 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.

After the statistics is finished, effective coverage cells of all terminals in each service connection state are generated, a first effective coverage cell list is generated as shown in table 2, the number of service terminals of the first effective coverage cell is counted, and a first service terminal number list is generated as shown in table 3.

TABLE 2

Illustratively, in conjunction with table 2, for XX0 terminals, the effective coverage cells with connection state indexes XX0-001 are XXX01 and XXX 02; for XX0 terminals, the effective coverage cell with connection state numbers XX0-002 is XXX 01.

TABLE 3

Cell identity	Number of service terminals
		XXX09	799
XXX23	797
		……	……
XXX03	10

Illustratively, after all effective coverage cells are determined, counting the terminal data covered by the effective coverage cells to obtain a list of the number of service terminals of the effective coverage cells as shown in table 3, where the larger the number of service terminals is, the more times the terminal serving the cell in a preset time period performs service connection is, the higher the value of cell opening is. The initial number of service terminals of each cell is 0. As can be seen from table 3, the service terminal number list contains 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 232, the base station energy saving device screens the cells in the service terminal number list according to the determined rule to obtain a first cell list.

Step 232 corresponds to step B.

The first cell list includes at least one cell.

Since the service terminal number list is arranged in descending order according to the number of terminals that can be served by the cell, the first n1 cells in the service terminal number list are selected as the starting cells according to the processing rule, and a first cell list is formed. Specifically, the processing rule is as follows: taking a single measurement report as an example, counting the number of the neighbor cells of which the signal quality is greater than or equal to the second threshold and the signal-to-noise ratio is greater than or equal to the third threshold in the measurement report to obtain the number of the effective coverage neighbor cells, wherein the number of the effective coverage cells is equal to the number of the effective coverage neighbor cells plus 1. And respectively calculating the number of the effective coverage cells of each test report to obtain an effective coverage cell list.

Measurement report sequence number	Number of cells covered effectively
		0000001	3
0000002	2
		……	……
000X00X	2

Illustratively, in conjunction with the processing rules, a list of the number of effective coverage cells is obtained as shown in table 4. Wherein, the number of the corresponding effective coverage cells of the measurement report with the measurement report serial number of 0000001 is 3; the number of the corresponding effective coverage cells is 2 for the measurement report with the measurement report serial number of 0000002; the measurement report with the measurement report number of 000X00X corresponds to 2 effective coverage cells.

n1 NS/(mean of number of effective coverage cells + variance of number of effective coverage cells)

Where NS is the total number of cells included in the target region, and n1 is the result of rounding up in conjunction with the above formula.

And combining the service terminal number list, judging whether the starting condition is met from the first-ranked cell, wherein the starting condition is that all adjacent cells of the current cell are not in the first cell list, if the starting condition is met, listing the current cell in the first cell list, judging whether the next cell meets the condition according to the descending order of the service terminal number list, and selecting n1 cells by analogy to form a final first cell list.

TABLE 5

Serial number	Cell identity
			1	XXX09
2	XXX23
		……	……
n1	XXX03

Illustratively, the serving terminal number list and the processing rule are combined to obtain a first cell list as shown in table 5. Wherein, the first open cell is XXX09, the second open cell is XXX23, and the n1 th open cell is XXX 03.

And 233, repeating the step a and the step B until the generated effective service cell list is empty, and the corresponding cell list is an open cell list.

In an implementable manner, in combination with step 231 and step 232, step a and step B are repeatedly executed until the generated effective serving cell list is empty, and the corresponding cell list is an open cell list.

Illustratively, polling is started from a first piece of data in a first effective serving cell list, if an effective coverage cell in the piece of data belongs to the first cell list, the piece of data is deleted from the first effective serving cell list, and each piece of data is polled in sequence until the last piece of data is judged, so as to form a second effective serving cell list.

Polling each piece of data of the second effective service cell list based on the calculation mode of the second effective service cell list and the first service terminal number list, determining the number of service terminals corresponding to the rest un-started cells by counting each piece of data in the second effective service cell list, and arranging the number of the service terminals of the un-started cells in a descending order to form a second service terminal number list.

TABLE 6

Cell identity	Number of service terminals
		XXX38	333
XXX13	310
		……	……
XXX02	5

According to the second effective serving cell list, the second serving terminal number list shown in table 6 is obtained by counting the terminal data covered by the effective coverage cells in the second effective serving cell list. As can be seen from table 6, the service terminal number list contains N pieces of data. The number of terminals served by the cell with the cell identifier XXX38 is maximum, namely 333; the cell service terminal with the cell identifier XXX13 is used for a plurality of times, namely 310 times; the cell identified as XXX02 has the least number of cell service terminals, 5.

And according to the second effective service cell list, judging whether the starting condition is met or not from the cell ranked first in the second effective service cell list, wherein the starting condition is that all adjacent cells of the current cell are not in the second cell list, if the starting condition is met, listing the current cell in the second cell list, judging whether the next cell meets the condition or not according to the descending order of the service terminal number list, and selecting n2 cells by analogy to form a final second cell list. Specifically, n2 satisfies the following formula:

n2 NS/average of effective coverage cells-n 1

Where NS is the total number of cells included in the target region, and n2 is the result of rounding up in conjunction with the above formula.

And starting polling from the first piece of data in the second effective service cell list, deleting the piece of data from the second effective service cell list if one effective coverage cell in the piece of data belongs to the second cell list, and polling each piece of data in sequence until the last piece of data is judged to form a third effective service cell list. Exemplarily, refer to table 2.

Polling each piece of data of the third effective service cell list based on the calculation mode of the third effective service cell list and the first service terminal number list, determining the number of service terminals corresponding to the rest un-started cells by counting each piece of data in the third effective service cell list, and arranging the number of the service terminals of the un-started cells in a descending order to form a third service terminal number list. Exemplarily, refer to table 6.

And according to a third effective service cell list, judging whether a starting condition is met or not from a cell ranked first in the third effective service cell list, wherein the starting condition is that all adjacent cells of the current cell are not in the third cell list, if the starting condition is met, listing the current cell in the third cell list, judging whether a next cell meets the condition or not according to the descending order of the service terminal number list, and selecting n3 cells by analogy to form a final third cell list. In connection with step 131, n3 satisfies the following equation:

And arranging the number of the service terminals covered by each cell in the first effective coverage list in a descending order, and taking the number of the service terminals corresponding to the measurement report of K% of the positions, wherein K is an integer of 50-100 and is 60 as an example. According to the third effective service cell list, if the number of data in the third effective service cell list is less than X, the number of service terminals corresponding to the measurement report at the k% position directly takes the average value of the number of service terminals in the first effective coverage list, which is equivalent to that the third cell list is not obtained in this case. And starting polling from the first piece of data in the third effective service cell list, if one effective coverage cell in the piece of data belongs to the third cell list, deleting the piece of data from the third effective service cell list, and polling each piece of data in sequence until the last piece of data is judged to form a fourth effective service cell list. Exemplarily, refer to table 2.

And in a polling preset time period, when a measurement report list acquired in a service connection state, a terminal identifier and a connection number state in the measurement report list belong to a fourth effective service cell list, the data are reserved, otherwise, the data are deleted, and a fourth measurement report list is formed.

For the terminal identification number XX0, counting all measurement reports of the terminal in each service connection state to obtain the ratio of good quality points of all the inter-system neighboring cells involved in each service connection state. Illustratively, according to the target measurement report list, when the terminal identified as XX0 is in the first service connection state, the reported neighbor cells of the heterogeneous system include cell E and cell F.

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

step m'/step t

Wherein, the step t is the total number of the measurement reports obtained by the XX0 terminal in the first service connection state; step m' 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 E (both neighbor cells and serving cells) is included; the quality of the cell E signal is greater than or equal to a fifth preset threshold; and the signal-to-noise ratio of the cell E is greater than or equal to a sixth preset threshold.

And obtaining the value of R '(the quality good point proportion of the service cell E) through the formula, if the value of R' is greater than or equal to a seventh preset threshold value, determining that the cell E is a foreign system 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 E.

By combining the above calculation modes, calculating R 'values of the XX0 terminal in the first service connection state and the related cell E and cell F, respectively, and then determining whether the cell E and cell F are cells effectively covered by the different systems of the XX0 terminal in the first connection state, if the R' values of the cell E and cell F meet the requirement, the cell E and cell F are also cells effectively covered by the different systems of the XX0 terminal in the first connection state, and meanwhile, the number of the service terminals of the cell E and cell F is respectively increased by one; if the requirement is not met, the cell which does not meet the requirement is not a cell which is effectively covered by the XX0 terminal in the first connection state of the heterogeneous system, 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 service terminals of the XX0 terminal in the second service connection state, which effectively cover the cell and the cell of the different system.
