The base station energy-saving method provided by the embodiment of the invention can be suitable for communication systems of operators. Fig. 1 shows a schematic structural diagram of the communication system. As shown in fig. 1, a communication system 10 includes a base station power saving device 11 and a base station management apparatus 12.

The base station power saving device 11 is connected to a base station management apparatus 12. The base station energy saving apparatus 11 and the base station management device 12 may be connected in a wired manner or in a wireless manner, which is not limited in the embodiment of the present invention.

The base station energy saving device 11 may be configured to perform data interaction with the base station management apparatus 12, for example, the base station energy saving device 11 may acquire a service parameter of a cell of a base station in a preset time period from the base station management apparatus 12.

The base station management device 12 may be configured to receive the identifier of the base station to be turned off and the identifier of the base station to be turned on, which are sent by the base station energy saving device 11, turn off the base station according to the identifier of the base station to be turned off, and turn on the base station according to the identifier of the base station to be turned on.

It should be noted that the base station energy saving apparatus 11 and the base station management device 12 may be independent devices, or may be integrated into the same device, and the present invention is not limited to this.

When the base station energy saving device 11 and the base station management apparatus 12 are integrated into the same apparatus, the communication mode between the base station energy saving device 11 and the base station management apparatus 12 is communication between internal modules of the apparatus. In this case, the communication flow between the base station energy saving device 11 and the base station management apparatus 12 is the same as the "communication flow between the two when they are independent of each other".

In the following embodiments provided by the present invention, the present invention is described by taking an example in which the base station energy saving device 11 and the base station management apparatus 12 are set independently of each other.

The following describes an energy saving method for a base station according to an embodiment of the present invention with reference to the accompanying drawings.

As shown in fig. 2, the method for saving energy of a base station according to the embodiment of the present invention includes steps S201 to S213:

s201, the base station energy saving device 11 obtains a service parameter of the first cell in a time period included in a first preset time period.

The first cell is any one of a plurality of cells included in the target area, and the service parameter is used for reflecting the size of the service volume of one cell in a time period. The time period is a statistical period of the service parameters.

It should be noted that the range of the target area may be set in the base station energy saving device 11 by an operation and maintenance person of the communication system in advance, specifically, the operation and maintenance person may divide the wireless communication network into a plurality of energy saving areas, where each energy saving area includes a plurality of base stations, and each base station is used to cover at least one cell. The target area may be any one of the plurality of energy saving areas. In an energy-saving area, the network systems of each base station can be the same or different, and all the base stations are equipped with the same identifier of the energy-saving area.

As a possible implementation, the base station energy saving device 11 may send a data request message to the base station management apparatus 12 according to the identification of the target area.

The data request message includes an identifier of a target area and an identifier of a base station of each cell in the target area, and the data request message is used for requesting to acquire the traffic of each cell in the target area in a time period included in a first preset time period.

It should be noted that the duration of the first preset duration may be preset in the base station energy saving device 11 by operation and maintenance staff. The first preset time period may include a plurality of the same time periods.

For example, the first preset time period may be 1 day, and the preset time period may be 15 minutes.

Accordingly, the base station management device 12, after receiving the data request message, communicates with the base stations in the target area in response to the data request message, acquires the traffic volume of the cell of the base station in each time slot from the base stations in the target area, and sends the acquired traffic volume of each cell in each time slot to the base station energy saving device 11.

Further, after receiving the traffic of the first cell sent by the base station management device 12, the base station energy saving device 11 may determine the traffic parameter of the first cell in each time period according to the received traffic.

The traffic of the first cell may include uplink and downlink traffic of the cell, the number of Radio Resource Control (RRC) connected users, and the number of activated users.

In one case, the base station energy saving device 11 may use any one of the above-mentioned 3 parameters of the first cell in a time slot as the traffic parameter of the first cell in a time slot.

In another case, the base station energy saving device 11 may further set weights for at least two of the 3 parameters, and perform weighted summation on the at least two parameters of the first cell in a time period, so as to obtain the service parameters of the first cell in the time period.

It should be noted that the weight of each parameter included in the traffic may be preset in the base station energy saving device 11 by an operation and maintenance worker.

S202, the base station energy saving device 11 determines a first time period corresponding to the first cell.

The service parameter of the cell in the first time period is less than or equal to a first threshold, and the first time period is a time period within a time period included in a first preset time period.

As a possible implementation manner, the base station energy saving device 11 determines, according to the size of the service parameter in the time period included in the first preset time period of the first cell, a time period, in which the service parameter is smaller than or equal to the first threshold, from a plurality of time periods in the first preset time period, as the first time period corresponding to the first cell.

It should be noted that the first threshold may be set in the base station energy saving device 11 by operation and maintenance personnel in advance.

S203, the base station energy saving device 11 obtains the number of the first time periods corresponding to the first cell.

As a possible implementation manner, after determining the first time period corresponding to the first cell, the base station energy saving device 11 further obtains the number of the first time periods corresponding to the first cell included in the first preset time period.

S204, the base station energy saving device 11 determines whether the first cell satisfies the first condition.

Wherein the first condition comprises: the ratio of the number of the first time periods corresponding to the first cell to the number of the time periods included in the first preset time is greater than the second threshold.

As a possible implementation manner, the base station energy saving device 11 obtains the number of time periods included in the first preset time period, and calculates to obtain a ratio of the number of the first time periods corresponding to the first cell to the number of the time periods included in the first preset time period, so as to further determine whether the ratio is greater than the second threshold.

It should be noted that the second threshold may be set in the base station energy saving device 11 by operation and maintenance personnel in advance.

S205, the base station energy saving device 11 determines that the first cell is the first target cell if the first cell satisfies the following first condition.

As a possible implementation manner, the base station energy saving device 11 regards the first cell as the first target cell when determining that the first cell satisfies the first condition.

S206, the base station energy saving device 11 obtains the first energy consumption value and the second energy consumption value.

The first energy consumption value is the sum of the energy consumption values of the base stations of the plurality of cells in a first preset time period, and the second energy consumption value is the sum of the energy consumption values of the base stations of the first target cell in the first preset time period.

The energy consumption value of a base station can be determined according to the energy consumption parameters (maximum power consumption, power efficiency or bit energy consumption) of the base station equipment of the base station.

The maximum power consumption is the maximum power of the base station equipment in the operation process, the power efficiency is the ratio of the output power to the input power of the base station equipment, and the bit energy consumption is the ratio of the output power to the service rate of the base station equipment.

In one case, the base station energy saving device 11 may use any one of the 3 energy consumption parameters during a time period of the base station of the first cell as the energy consumption value of the base station of the first cell during a time period.

In another case, the base station energy saving device 11 may further set a weight for at least two energy consumption parameters of the 3 energy consumption parameters, and perform weighted summation on the at least two energy consumption parameters of the base station of the first cell in a time period to obtain an energy consumption value of the base station of the first cell in the time period.

It should be noted that the weight of each parameter included in the energy consumption parameter may be preset in the base station energy saving device 11 by an operation and maintenance worker.

S207, the base station energy saving device 11 determines a second time period corresponding to the second cell.

The second cell includes any cell except the first target cell in the target area, and the service parameter of the cell in the second time period is greater than the third threshold. The second time period is a time period within the time period included in the first preset time period. The third threshold is greater than or equal to the first threshold.

As a possible implementation manner, the base station energy saving device 11 determines, according to the size of the service parameter of the second cell in each time period of the first preset time period, a second time period corresponding to the second cell from the time periods included in the first preset time period.

It should be noted that the third threshold may be set in the base station energy saving device 11 by operation and maintenance personnel in advance.

It can be understood that the second cell is any cell that does not satisfy the first condition among all cells included in the target area.

S208, the base station energy saving device 11 determines at least one third time period corresponding to the second cell.

The third time period comprises a plurality of continuous first time periods, and the duration of each third time period is greater than a fourth threshold.

As a possible implementation manner, after determining the first time period, which is included in the first preset time period, of the second cell and corresponds to the second cell, the base station energy saving device 11 determines, according to the time sequence and the time period among the multiple determined first time periods, at least one third time period corresponding to the second cell from the first preset time period.

It should be noted that the fourth threshold may be set in the base station energy saving device 11 by operation and maintenance personnel in advance.

In the embodiment of the present invention, the sequence between steps S206, S207 and S208 is not limited, and in practical applications, S206 may be executed first, and then S207 or S208 is executed, or S207 may be executed first, and then S206 or S208 is executed, or S208 may be executed first, and then S206 or S207 is executed, or S206, S207, and S208 may be executed simultaneously.

Optionally, in a case that the time of each preset time period is the same, each third time period may also be determined based on the number of the first time periods included in the third time period.

S209, the base station energy saving device 11 determines at least one fourth time period corresponding to the second cell.

Wherein the fourth time period comprises a plurality of consecutive second time periods.

As a possible implementation manner, after determining the second time period corresponding to the second cell, the base station energy saving device 11 determines the fourth time period from within the first preset time period according to the time sequence of the determined second time period.

After S207, the base station energy saving device 11 performs S209 according to the determination result of S207.

S210, the base station energy saving device 11 determines whether a difference between the first energy consumption value and the second energy consumption value is smaller than or equal to a fifth threshold.

As a possible implementation manner, the base station energy saving device 11 calculates a difference between the first energy consumption value and the second energy consumption value, and determines a size of the calculation result and the fifth threshold.

Note that the fifth threshold may be set in the base station energy saving device 11 by operation and maintenance personnel in advance.

S211, the base station energy saving device 11 determines whether the second cell meets the second condition when the difference between the first energy consumption value and the second energy consumption value is smaller than or equal to the fifth threshold.

Wherein the second condition comprises: the average duration of at least one third time period corresponding to the second cell is greater than a sixth threshold, and the average duration of at least one fourth time period corresponding to the second cell is greater than a seventh threshold.

As a possible implementation manner, the base station energy saving device 11 determines whether the second cell satisfies the second condition according to the determined average duration of the at least one third time period corresponding to the second cell and the determined average duration of the at least one fourth time period corresponding to the second cell.

It should be noted that the sixth threshold and the seventh threshold may be set in the base station energy saving device 11 by operation and maintenance personnel in advance.

In another judgment result, if the base station energy saving device 11 determines that the difference between the first energy consumption value and the second energy consumption value is greater than the fifth threshold, after the first preset time period, the above S201 to S211 are executed again.

S212, the base station energy saving device 11 determines that the second cell is the second target cell if the second cell satisfies the second condition when the difference between the first energy consumption value and the second energy consumption value is smaller than or equal to the fifth threshold.

As one implementation manner, the base station energy saving device 11 regards the second cell as the second target cell in case that it is determined that the second cell satisfies the second condition.

In another judgment result, if the base station energy saving device 11 determines that the second cell does not satisfy the second condition, after a first preset time period, the foregoing S201 to S212 are executed again, or the following method provided by the embodiment of the present invention is executed.

S213, the base station energy saving device 11 shuts down the base station of the first target cell and the base station of the second target cell.

The base station energy saving device 11 is configured to, in order to close the base station where the first target cell is located and the base station where the second target cell is located, send a close instruction to the base station where the first target cell is located through the base station management device 12, so that the base station where the first target cell is located is in a closed state, and also send a close instruction to the base station where the second target cell is located through the base station management device 12, so that the base station where the second target cell is located is in a closed state.

It can be understood that the first target cell is a cell with a low average traffic volume in the target area, and the embodiment of the present invention can ensure the energy saving effect of the base station on the premise of not affecting the performance of the communication network by using the above technical means.

It can be understood that the second target cell is a cell in which the high traffic and the low traffic in the target area have longer duration and the traffic variation is relatively stable. When the energy consumption of the base station in the target area is too large, the second target cell can be closed, so that the energy conservation of the base station is ensured under the condition that the energy consumption of the base station is not influenced.

In one design, in order to ensure stable performance of a communication network in a target area, with reference to fig. 3, the method for saving energy of a base station provided in an embodiment of the present invention further includes following steps S301 to S305.

S301, the base station energy saving device 11 obtains the number of the second time periods corresponding to the third cell.

The third cell includes any one of the cells in the target area except the first target cell and the second target cell.

As a possible implementation manner, after determining the second time period corresponding to the third cell, the base station energy saving device 11 determines the number of the second time periods corresponding to the third cell in the first preset time period.

In this step, the second time period corresponding to the third cell is determined, which may specifically refer to the description in S207 above, and is not described herein again.

S302, the base station energy saving device 11 determines whether the third cell satisfies the third condition.

Wherein the third condition includes: the ratio of the number of the second time periods corresponding to the third cell to the number of the time periods included in the first preset time duration is greater than an eighth threshold.

As a possible implementation manner, the base station energy saving device 11 determines whether the third cell satisfies the third condition according to the number of the second time periods corresponding to the third cell.

Note that the eighth threshold may be set in advance in the base station energy saving device 11 by an operation and maintenance person.

S303, if it is determined that the third cell meets the third condition, the base station energy saving device 11 determines the third cell as a third target cell, and determines that the base station of the third target cell is in an on state.

As a possible implementation manner, in a case that the third cell satisfies the third condition, the base station energy saving device 11 sends an on message through the base station management apparatus 12, so as to ensure that the base station where the third target cell is located is in an on state.

S304, if it is determined that the third cell does not satisfy the third condition, the base station energy saving device 11 determines whether the third cell satisfies the fourth condition.

Wherein, the fourth condition includes: the average duration of at least one third time period corresponding to the third cell is less than or equal to a sixth threshold, and the average duration of at least one fourth time period corresponding to the third cell is less than or equal to a seventh threshold.

As a possible implementation manner, the base station energy saving device 11 determines at least one third time period corresponding to the third cell and at least one fourth time period corresponding to the third cell, and determines whether the third condition satisfies the fourth condition when the third condition is not satisfied according to the at least one third time period corresponding to the third cell and the at least one fourth time period corresponding to the third cell.

In this step, reference may be made to the foregoing S208 for determining the implementation manner of the at least one third time period corresponding to the third cell, which is not described herein again. In this step, the implementation manner of determining at least one fourth time period corresponding to the third cell may refer to S304 described above, and is not described herein again.

S305, if the third cell meets the following fourth condition, the base station energy saving device 11 determines that the third cell is a fourth target cell, and determines that the base station of the fourth target cell is in an on state.

As a possible implementation manner, in a case that the third cell satisfies the fourth condition, the base station energy saving device 11 sends an on message through the base station management apparatus 12, so as to ensure that the base station where the third target cell is located is in an on state.

In another determination result, if the third cell does not satisfy the fourth condition, the base station energy saving device 11 does not process the third cell.

It can be understood that the embodiment of the present invention provides four conditions, which correspond to four cell models, where the cell model corresponding to the third condition can determine a third target cell with a larger time period of high traffic in the target area, which reflects that the average traffic of the third target cell is larger. The cell model corresponding to the fourth condition can determine that the duration of high traffic and low traffic in the target area is short, and the traffic has a fourth target cell with mutation type and randomness. Furthermore, each cell in the target area can be assigned to different cell models, and then the cells of different models can be selected to be closed or opened according to the energy consumption condition of the base station in the target cell, so that the close or open of each cell in the target area can be finely managed.

In one design, in order to adapt to the service change of the second target cell and the fourth target cell and improve the accuracy of turning off or on the cell, as shown in fig. 4, the method for saving energy of a base station according to the embodiment of the present invention further includes following steps S401 to S405.

S401, the base station energy saving device 11 determines a first period of the fourth cell.

The fourth cell is any one of the first target cell, the second target cell, the third target cell and the fourth target cell, and the duration of the first period is less than or equal to the duration of a first preset duration. The first period is an update period for determining whether the fourth cell satisfies a preset condition. The above S201 to S213 and S301 to S305 are repeatedly performed at the first cycle.

As a possible implementation manner, the base station energy saving device 11 may calculate a product of the first preset duration and a preset adjustment coefficient as the first period of the fourth cell.

It should be noted that the preset adjustment coefficient may be set in the base station energy saving device 11 by an operation and maintenance person in advance. The interval range of which the adjusting coefficient meets (0, 1) is preset.

In another case, the first period may also be determined by the base station energy saving device 11 according to a preset method, and for the specific implementation of determining the first period, reference may be made to the following description of the embodiment of the present invention, and details are not described here again.
