In the actual working process of the base station, the signal transmitting power of the base station is always larger so as to ensure that each terminal in the signal coverage range of the base station has better communication quality, but the base station is operated in the mode to consume more energy. In order to save energy, a base station energy saving method needs to be provided.

The character "/" generally indicates that the context-dependent object is an "or" relationship.

The term "plurality" in embodiments of the present invention means two or more, and other adjectives are similar.

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention are included in the scope of protection of the present invention.

In order to reduce energy consumption of a base station, the embodiment of the invention provides a base station energy saving method, a base station and a device.

The invention provides a base station energy saving method, which comprises the following steps:

if yes, the signal transmitting power of the cell is reduced.

Fig. 1 is a flow chart of a first base station energy saving method according to an embodiment of the present invention, which is applied to a base station, and for each cell of the base station, as shown in fig. 1, the method may include the following steps: S101-S103.

Step S101: first information and second information of the cell are acquired.

Wherein the first information indicates: the base station uses the signal corresponding to the cell to perform transmission efficiency when transmitting data, and the second information indicates: the distance between the terminal accessing the cell and the base station.

Specifically, the base station may transmit different signals in different directions, each corresponding to one cell, and thus, one base station may have a plurality of cells. For each cell of the base station, the base station acquires first information and second information of the cell.

Specifically, the first information indicates transmission efficiency when the base station uses the signal corresponding to the cell to perform data transmission, for example: the spectrum efficiency, the demodulation reference signal, the signal quality parameter, etc. may be used as the first information, where the second information indicates the distance between the terminal accessing the cell and the base station, for example: the statistics of the TA (time advanced, maximum time advance) value of the terminal accessing the cell may be used as the second information.

In one embodiment of the present invention, the first information of the cell acquired by the base station is the spectrum efficiency of the signal corresponding to the cell transmitted by the base station, and the second information of the cell acquired by the base station is the statistical value of the TA value of the terminal accessing the cell, where the base station may obtain different TA values of each terminal accessing the cell, and on the basis of the statistical value of each TA value obtained, the statistical value of the TA value may be obtained, for example: the statistical value of the TA value may be a maximum TA value of each terminal accessing the cell, a minimum TA value of each terminal accessing the cell, or an average TA value of each terminal accessing the cell.

In addition, the base station may continuously acquire the first information and the second information based on a first preset period.

In another embodiment of the present invention, an energy saving start time and an energy saving end time may be set manually, where a base station starts to acquire first information and second information of the cell at the energy saving start time, that is, starts to execute the base station energy saving method provided by the embodiment of the present invention, and the base station stops acquiring the first information and the second information of the cell at the base station end time, that is, ends to execute the base station energy saving method provided by the embodiment of the present invention. Such as: in the daytime, the terminals connected with the base station are often more, so that each terminal has better communication quality, energy conservation is not needed, in the evening, the terminals connected with the base station are often less, and even if the signal transmitting power of the base station is reduced, each terminal can be guaranteed to have better communication quality, therefore, energy conservation can be carried out, and the energy conservation starting time and the energy conservation ending time can be artificially set at the evening. Specifically, the user may set the energy saving start time and the energy saving end time according to the historical statistics result of the number of terminals accessing the base station in different time periods.

Step S102: and judging whether the first information is larger than a first information preset threshold and whether the second information is smaller than a second information preset threshold.

If yes, executing step S103, otherwise, ending the flow, or returning to executing steps S101-S102 to continue to judge whether the signal transmitting power can be reduced.

Specifically, the first information preset threshold is set based on the first information, for example, the first information is spectrum efficiency, and the first information preset threshold may be set to 80, 85, 90, or the like; the second information preset threshold is set based on the second information, for example, the second information is a statistical value of a TA value of a terminal accessing the cell, and a unit of the statistical value of the TA value is ms, and the second information preset threshold may be set to 10ms, 20ms, 30ms, or the like.

In another embodiment of the present invention, the step a may further implement the step S102, which is described in detail in the following embodiments, which will not be described in detail herein.

Step S103: if the judgment result is yes, the signal transmitting power of the cell is reduced.

Specifically, if the first information is greater than the first information preset threshold and the second information is less than the second information preset threshold, it is indicated that the transmission efficiency of the base station when using the signal corresponding to the cell to perform data transmission is higher, and the distance between the terminal accessing the cell and the base station is smaller, which indicates that the cell can provide better communication quality for the terminal accessing the cell, so that the signal transmitting power of the cell can be reduced.

In one embodiment of the present invention, the reduced target signal transmitting power may be preset, so that when the signal transmitting power needs to be reduced, the signal transmitting power of the cell may be directly reduced to the target signal transmitting power, and the target signal transmitting powers corresponding to different cells may be different.

In another embodiment of the present invention, the decreasing amplitude of the signal transmitting power may be preset, and when the signal transmitting power needs to be decreased, the preset decreasing amplitude may be decreased based on the current signal transmitting power of the cell, and the decreasing amplitudes corresponding to different cells may be different.

Alternatively, the step S103 may be performed by steps S103A to S103B shown in fig. 4, which will not be described in detail here.

In addition, as can be seen from the above, the process of implementing the base station energy saving in the embodiment of the present invention does not need to change the physical structure of the base station, and the above process can be implemented by software, so that the base station energy saving method provided in the embodiment of the present invention can be configured for the base station by upgrading the base station software, and thus the base station energy saving can be implemented simply and conveniently.

In addition, the execution body of the present solution may be OM (Base station operation and maintenance sub module, base station operation maintenance submodule), where OM is a software module in a base station, and when executing the step S101, the OM may first send first request information and second request information of the cell to a base station HL (High Layer), where the base station HL sends the first information of the cell to the OM after receiving the first request information, and where the base station HL sends the second information of the cell to the OM after receiving the second request information.

In addition, the embodiment of the invention judges whether to reduce the signal transmitting power of the cell based on the transmission efficiency of the base station when transmitting data by using the signal corresponding to the cell and the distance between the base stations of the terminal accessed to the cell, and the traditional energy-saving mode judges whether to reduce the signal transmitting power of the cell based on the resource utilization of the cell to save energy.

The difference between the base station energy saving process of the embodiment of the invention and the base station energy saving process of the prior art is described below by specific examples, taking a school scene as an example, the user may be distributed at all positions of the school during the daytime, the distribution of the terminals used by the user is more dispersed, but at night, the user is often concentrated in dormitory buildings, and the distribution of the terminals used by the user is more concentrated. The embodiment of the invention saves energy based on the transmission efficiency of the base station when the base station uses the signals corresponding to the cell to transmit data and the distance between the terminal accessed to the cell and the base station, and when the users are intensively distributed in the same area, namely the terminals used by the users are intensively distributed in the same area, the distance between the terminal and the base station is smaller, the embodiment of the invention can trigger the base station to start energy saving when the transmission efficiency of the base station uses the signals corresponding to the cell to transmit data is higher. The energy of the base station is saved by reducing the signal transmission power, and the coverage area of the cell is reduced after the signal transmission power is reduced, but the coverage area of the smaller cell can also meet the normal communication requirement of the terminal because the terminal distribution is more concentrated. Therefore, under the partial scene that the base station energy conservation is difficult to carry out by adopting the prior art, the base station energy conservation can be carried out by adopting the embodiment of the invention, and the normal communication of the terminal can be ensured while the energy conservation is carried out. In addition, the embodiment of the invention can also be applied to application scenes such as squares, office buildings, markets and the like.

In the embodiment of the invention, the cell is taken as a unit to judge whether the base station corresponding to the cell needs energy conservation, so the invention can be applied to a single-layer network with only one cell in a certain area or a multi-layer network with a plurality of cells in a certain area.

In one embodiment of the present invention, the step S102 may be implemented through step a.

Step A: judging whether each piece of first information acquired in the first preset time period is larger than a first information preset threshold or not, and whether each piece of second information acquired in the second preset time period is smaller than a second information preset threshold or not.

Specifically, the magnitude relation between the first preset duration and the second preset duration is not limited in the embodiment of the present invention, that is, the first preset duration may be equal to the second preset duration, or the first preset duration may be greater than the second preset duration, or the first preset duration may be less than the second preset duration.

In one embodiment of the present invention, if each piece of first information acquired in the first preset duration is greater than a first information preset threshold and each piece of second information acquired in the second preset duration is smaller than a second information preset threshold, it is indicated that the first information of the cell is greater than the first information preset threshold and the second information of the cell is smaller than the second information preset threshold in a long period of time, which may indicate that the transmission efficiency of the base station when using the signal corresponding to the cell for data transmission is higher and the distance between the terminal accessing the cell and the base station is smaller.

In another embodiment of the present invention, the base station may continuously acquire the first information and the second information based on a first preset period, then the base station may set a first information counter to 0 and a second information counter to 0, then for each first information acquired, increment the first information counter by 1 if the first information is greater than the first information preset threshold, otherwise reset the first information counter to 0, and then for each second information acquired, increment the second information counter by 1 if the second information is greater than the second information preset threshold, and otherwise reset the second information counter by 0. If the product of the first preset period and the count value of the first information counter is greater than the first preset duration, the first information acquired in the first preset duration is greater than a first information preset threshold. If the product of the first preset period and the count value of the second information counter is greater than the second preset duration, the second information acquired in the second preset duration is smaller than a second information preset threshold.

From the above, the base station can continuously determine whether each first information acquired in the first preset duration is greater than the first information preset threshold and whether each second information acquired in the second preset duration is smaller than the second information preset threshold, and only if each first information is greater than the first information preset threshold and each second information is smaller than the second information preset threshold, the base station considers that the transmission efficiency is higher when the base station uses the signal corresponding to the cell to perform data transmission, and the distance between the terminal connected to the cell and the base station is smaller, so that the signal transmitting power of the cell is reduced. Compared with the method for judging whether the signal transmission power of the cell is directly reduced by only acquiring one piece of first information and one piece of second information, and then directly reducing the signal transmission power of the cell when the first information is larger than a first information preset threshold and the second information is smaller than the first information preset threshold, the method for judging whether the signal transmission power is reduced in the embodiment of the invention has more strict conditions, and can prevent the signal transmission power from being directly reduced under the condition that the transmission efficiency is instantaneously higher and the distance between a terminal connected to the cell and a base station is smaller, thereby influencing the normal communication of the terminal.

Fig. 2 is a flow chart of a second base station energy saving method according to an embodiment of the present invention, as shown in fig. 2, after step S103, the method may further include the following steps: S104-S105.

Step S104: first information and second information of the cell are acquired.

Specifically, after the signal transmitting power of the base station is reduced, the first information and the second information are continuously acquired, that is, the transmission efficiency of the base station when the base station uses the signal corresponding to the cell to perform data transmission and the distance between the terminal and the base station in the cell are continuously monitored.

In one embodiment of the present invention, the implementation of this step is already described in step S101 above, and will not be described in detail here.

Step S105: and if the first information is smaller than the first information preset threshold or the second information is larger than the second information preset threshold, recovering the signal transmitting power of the cell to the first signal transmitting power.

Wherein, the first signal transmitting power is: the signal transmission power of the cell is reduced before the signal transmission power.

Specifically, the first signal transmission power is the signal transmission power of the cell before the signal transmission power is reduced, that is, the first signal transmission power is greater than the current signal transmission power of the cell.

In addition, if the first information is smaller than the first information preset threshold, it is indicated that the transmission efficiency of the base station when using the signal corresponding to the cell for data transmission is lower, and the transmission efficiency of the base station when using the signal corresponding to the cell for data transmission needs to be improved by improving the signal transmission power of the cell; if the second information is greater than the second information preset threshold, it is indicated that the distance between the terminal accessing the cell and the base station is longer, and the signal transmitting power of the cell needs to be increased, so that the terminal farther from the base station can also be connected with the signal transmitted by the cell, and if any one of the conditions occurs, the signal transmitting power of the cell can be recovered to the first signal transmitting power.

In an embodiment of the present invention, in this step, whether the first information is smaller than a first information preset threshold or whether the second information is larger than a second information preset threshold may be determined in a similar manner to that in the step a, which is not described herein.

Specifically, restoring the signal transmission power of the cell to the first signal transmission power is equivalent to backing the signal transmission power of the cell back to the power before reducing the signal transmission power, so that the base station operates again in a high-energy-consumption state, that is, the embodiment of the invention provides the energy-saving back-off detection function.

From the above, if the first information is greater than the first information preset threshold, it indicates that the transmission efficiency of the base station when using the signal corresponding to the cell to perform data transmission is poor, and if the second information is less than the second information preset threshold, it indicates that the distance between the terminal accessing the cell and the base station is large, so that any one of the above situations occurs, it can indicate that the signal transmitting power of the current cell cannot provide better communication quality for the terminal, so that energy saving can be abandoned, the signal transmitting power of the cell can be improved, and better communication quality can be provided for the terminal accessing the cell. Therefore, the embodiment of the invention provides the energy-saving back-off detection function, and gives up energy saving when the signal transmitting power of the cell is insufficient, thereby ensuring the communication experience of the terminal to the greatest extent.

Fig. 3 is a flow chart of a third base station energy saving method according to an embodiment of the present invention, as shown in fig. 3, after step S103, the method further includes the following steps: S106-S107.

Step S106: and determining the switching times of the terminal accessed to the cell in the third preset time.

Specifically, after the signal transmission power of the cell is reduced, the transmission efficiency of the base station when transmitting data by using the signal corresponding to the cell may be reduced, so that the terminal in the cell may not be able to access the cell and switch to other cells due to the lower transmission efficiency, or after the signal transmission power of the cell is reduced, the coverage area of the signal of the cell may be reduced, so that the terminal located in the coverage area of the cell before the signal transmission power of the cell is reduced, and after the signal transmission power of the cell is reduced, the terminal is no longer located in the coverage area of the cell, and the terminal may only switch to other cells.

In one embodiment of the present invention, the number of handover times may be set to 0 first, and then, within the third preset duration, when the base station receives the first request handover information sent by the terminal accessing the cell, the number of handover times is increased by 1, or the base station also adds 1 to the second request handover information sent by the terminal accessing the cell.

Step S107: and if the switching times are greater than the preset switching times, recovering the signal transmitting power of the cell to the first signal transmitting power.

In addition, if the number of switching times is greater than the preset number of switching times, it is indicated that the terminal accessing the cell is frequently switching cells, and it is further indicated that the current signal transmitting power of the cell cannot provide better communication quality for the terminal accessing the cell, so that the signal transmitting power of the cell can be recovered to the first signal transmitting power.

From the above, it can be seen that, first, the number of times of switching the cell by the terminal accessing the cell is determined, if the number of times of switching is greater than the preset number of times of switching, it is indicated that the transmission efficiency of the base station when using the signal corresponding to the cell to perform data transmission is lower, before the cell reduces the signal transmitting power, the terminal capable of accessing the cell is difficult to connect to the signal transmitted by the cell, or the coverage area of the signal of the cell is smaller, before the cell reduces the signal transmitting power, the terminal capable of accessing the cell is no longer located in the coverage area of the signal of the cell, thereby indicating that the current signal transmitting power cannot meet the normal communication requirement of the terminal accessing the cell, so that energy saving can be abandoned, the signal transmitting power of the base station can be improved, and good communication experience can be brought to the terminal accessing the cell.

Fig. 4 is a flow chart of a fourth base station energy saving method according to an embodiment of the present invention, as shown in fig. 4, compared with the embodiment shown in fig. 1, the step S103 may include the following steps: S103A-S103B.

Step S103A: if the judgment result is yes, determining the second signal transmitting power corresponding to the acquired second information based on the preset corresponding relation.

Wherein, the preset corresponding relation is as follows: and the corresponding relation between the second information and the signal transmitting power.

Specifically, the preset correspondence between the second information and the signal transmitting power may be: the larger the second information is, the larger the distance between the terminal and the base station in the cell is, and the higher the signal transmitting power of the cell needs to be set, so that the coverage area of the cell is larger, and each terminal in the cell can be covered; the smaller the above second information, the smaller the distance between the terminal and the base station in the cell, the smaller the signal transmitting power of the cell can be set, so that the coverage area of the cell is smaller, and more energy sources can be saved under the condition that each terminal in the cell can be covered.

In addition, each piece of second information may correspond to only one piece of second signal transmission power, or a plurality of pieces of second information may correspond to the same second signal transmission power.

In one embodiment of the present invention, the second information may be represented by a statistical value of TA values of terminals accessing the cell, and the preset correspondence relationship is: the correspondence between the statistic value of the terminal TA value and the second signal transmission power is as follows: the value of the second signal transmitting power corresponding to the statistical value of the TA value is m when the statistical value of the TA value is 0ms-10ms, the value of the second signal transmitting power corresponding to the statistical value of the TA value is n when the statistical value of the TA value is 11ms-20ms, the value of the second signal transmitting power corresponding to the statistical value of the TA value is 21ms-30ms is o, and the like, wherein o is larger than n and is larger than m.

Step S103B: the signal transmitting power of the cell is reduced to the second signal transmitting power.

From the above, it can be seen that, first, the second signal transmission power corresponding to the acquired second information is determined based on the preset correspondence, then, the signal transmission power of the cell is reduced to the second signal transmission power, because the larger the second information is, the higher the determined second signal transmission power is, and the smaller the second information is, the determined second signal transmission power is, so when the distance between the terminal accessing the cell and the base station is smaller, the base station can reduce the signal transmission power of the cell by the smaller second signal transmission power, and when the distance between the terminal accessing the cell and the base station is larger, the base station can reduce the signal transmission power of the cell by the larger second signal transmission power. Therefore, the embodiment of the invention can more flexibly select the signal transmitting power for the cell, so that the adjusted signal transmitting power is matched with the actual communication condition of the current terminal.

Fig. 5 is a flow chart of a fifth energy saving method for a base station according to an embodiment of the present invention, as shown in fig. 5, may include the following steps:

Step S501: the OM sends third request information and fourth request information to the HL based on the second preset period.

Specifically, OM sends the third request information to HL to obtain the spectrum efficiency of the signal corresponding to the cell transmitted by the base station, and sends the second request information to obtain the statistic value of the maximum time advance TA value of the terminal accessing the cell.

Step S502: HL, after receiving the first request information and the second request information, transmits the statistical values of the spectral efficiency and the TA value to OM.

Step S503: and OM judges whether the spectrum efficiency is larger than a third preset threshold according to each acquired spectrum efficiency.

If the spectrum efficiency is greater than the third preset threshold, step S504 is performed, otherwise step S505 is performed.

Step S504: the preset spectral efficiency counter is incremented by 1.

Step S505: the preset spectral efficiency counter is set to 0.

Step S506: and the OM judges whether the statistical value of each TA value is larger than a fourth preset threshold according to the acquired statistical value of each TA value.

If the statistical value of the TA value is greater than the fourth preset threshold, step S507 is executed, otherwise step S508 is executed.

Step S507: the preset TA value counter is incremented by 1.

Step S508: the preset TA value counter is set to 0.

Step S509: and if the product of the preset frequency spectrum efficiency counter and the second preset period is larger than the preset hysteresis time length and the product of the preset TA value counter and the second preset period is larger than the preset hysteresis time length, reducing the signal transmitting power of the cell.

Specifically, the specific implementation manner of step S501 to step S509 in the embodiment of the present invention is described in detail above, and will not be described herein.

Corresponding to the signal processing method applied to the base station, the embodiment of the invention also provides the base station.

Referring to fig. 6, a schematic structural diagram of a base station according to an embodiment of the present invention includes a memory 601, a transceiver 602, and a processor 603:

a memory 601 for storing a computer program; a transceiver 602 for receiving and transmitting data under the control of the processor; a processor 603 for reading the computer program in the memory and for each cell of the base station:

if yes, the signal transmitting power of the cell is reduced.

Wherein in fig. 6, a bus architecture may comprise any number of interconnected buses and bridges, and in particular one or more processors represented by the processor 603 and various circuits of the memory represented by the memory 601, linked together. The bus architecture may also link together various other circuits such as peripheral devices, voltage regulators, power management circuits, etc., which are well known in the art and, therefore, will not be described further herein. The bus interface provides an interface. The transceiver 602 may be a number of elements, including a transmitter and a receiver, providing a means for communicating with various other apparatus over a transmission medium, including wireless channels, wired channels, optical cables, etc. The processor 603 is responsible for managing the bus architecture and general processing, and the memory 601 may store data used by the processor 603 in performing operations.

The processor 603 may be a Central Processing Unit (CPU), an application specific integrated circuit (Application Specific Integrated Circuit, ASIC), a Field programmable gate array (Field-Programmable Gate Array, FPGA), or a complex programmable logic device (Complex Programmable Logic Device, CPLD), or the processor may employ a multi-core architecture.

The determining whether the first information is greater than a first information preset threshold and whether the second information is less than a second information preset threshold specifically includes:

Judging whether each piece of first information acquired in the first preset time period is larger than a first information preset threshold or not, and whether each piece of second information acquired in the second preset time period is smaller than a second information preset threshold or not.

From the above, the base station may continuously determine whether each first information acquired within the first preset duration is greater than the first information preset threshold and whether each second information acquired within the second preset duration is smaller than the second information preset threshold, and only if each first information is greater than the first information preset threshold and each second information is smaller than the second information preset threshold, the base station considers that the transmission efficiency is higher when using the signal corresponding to the cell to perform data transmission, and the distance between the terminal accessing the cell and the base station is generally smaller, the signal transmission power of the cell is reduced, and compared with the case that only one first information and one second information are acquired, and then the signal transmission power of the cell is directly reduced when the first information is greater than the first information preset threshold and the second information is smaller than the first information preset threshold, the condition of reducing the signal transmission power in the determination method provided by the embodiment of the present invention is more strict and can prevent the signal transmission power from being directly reduced under the conditions that the transmission efficiency is generally higher at the moment and the distance between the terminal accessing the cell and the base station is generally smaller, and the signal transmission power is directly affected.

The processor 603 is further configured to perform the following operations after the reducing the signal transmission power of the cell:

acquiring first information and second information of the cell;

In a further embodiment of the present invention, there is also provided a computer program product containing instructions which, when run on a computer, cause the computer to perform any of the signal processing methods of the above embodiments.

When the computer program product provided by the embodiment of the invention is applied to base station energy saving, the first information indicates the transmission efficiency when the base station uses the signal corresponding to the cell to perform data transmission, the second information indicates the distance between the terminal accessing the cell and the base station, and if the first information is larger than the first information preset threshold and the second information is smaller than the second information preset threshold, the transmission efficiency is higher and the distance between the terminal accessing the cell and the base station is smaller. In this case, if the signal transmission power of the cell is reduced, although the coverage area of the base station signal is reduced and the transmission efficiency of the base station for data transmission using the signal corresponding to the cell is reduced, the terminal in the coverage area of the base station signal theoretically has higher communication quality after the signal transmission power is reduced because the distance between the current terminal and the base station is small and the transmission efficiency is higher. In this case, the signal transmission power of the cell can be reduced, and the consumption of the base station energy can be reduced while ensuring the communication quality of the terminal.
