Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for determining a threshold.
Background
The fifth generation mobile communication (5G,5th generation mobile networks) base station requires higher hardware and software capabilities of the device and higher energy consumption than the fourth generation mobile communication (4G,4th generation mobile networks) base station. The high energy consumption means high cost, so in the deployment of the 5G base station, the idle period of the cell is determined, and then a corresponding energy-saving strategy is formulated, so that the purpose of saving energy consumption is achieved. Currently, the idle period of a cell is typically determined based on communication parameters, such as the traffic of the cell. For example, when the traffic volume of a cell is less than a threshold value within a certain period of time, the period of time may be determined as an idle period of the cell.
However, at present, when determining the idle period of the cell, the threshold value of the communication parameter is set manually and empirically, so the determined idle period of the cell is inaccurate.

Thereafter, a threshold value of the communication parameter is determined based on the historical data.
Since the communication parameters can characterize whether the cell is in an idle period (taking the traffic of the cell as an example, when the traffic of the cell in a certain period is low, the period is the idle period of the cell), and the communication parameters of the cell in different scene types in different periods are different, by analyzing the historical data of the communication parameters in a preset period corresponding to the scene type of the target cell, a threshold value of the communication parameters can be determined more reasonably.

Detailed Description
The following describes a method and an apparatus for determining a threshold according to an embodiment of the present application in detail with reference to the accompanying drawings.
The term "and/or" is herein merely an association relationship describing an associated object, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone.
The terms "first" and "second" and the like in the description and in the drawings are used for distinguishing between different objects or between different processes of the same object and not for describing a particular order of objects.
Furthermore, references to the terms "comprising" and "having" and any variations thereof in the description of the present application are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed but may optionally include other steps or elements not listed or inherent to such process, method, article, or apparatus.
It should be noted that, in the embodiments of the present application, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "for example" is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.
In the description of the present application, unless otherwise indicated, the meaning of "a plurality" means two or more.
With the rapid development of mobile communication technology, the fifth generation mobile communication (5G,5th generation mobile networks) base station has entered a stage of large-scale deployment. In order to meet the requirements of 5G rich service scenes, the requirements of the 5G base station on hardware and software capabilities of equipment are higher than those of the 4G base station, and the energy consumption is higher. Taking S111 single station as an example, the power consumption of the 5G single station base station device reaches about 4 times of the power consumption of the 4G single station device. Since high energy consumption means high cost, reducing the operation energy consumption of the 5G base station becomes a problem to be solved by each operator.
Currently, the idle period of a cell is determined based on communication parameters, such as the traffic of the cell. For example, when the traffic volume of a cell is less than a threshold value within a certain period of time, the period of time may be determined as an idle period of the cell. And then, a corresponding energy-saving strategy is formulated according to the determined idle time period of the cell, so that the aim of saving energy consumption is fulfilled.
It can be seen that the selection of the threshold value of the communication parameter is closely related to the accuracy of the idle period judgment. However, when determining the idle period of the cell, the threshold value of the communication parameter is set manually according to experience, so that the determined idle period of the cell is inaccurate, and the formulation of the energy-saving strategy is affected. For example, when the threshold value of the communication parameter is set too high, it may be that the busy time is determined as idle by mistake, and after the corresponding energy-saving strategy is formulated according to the idle time period determined by the threshold value, the network performance may be reduced, and the user experience may be affected. For another example, when the threshold of the communication parameter is set too low, the idle time may be erroneously determined as busy, and the energy saving purpose may not be achieved.
Aiming at the problems in the prior art, the embodiment of the application provides a threshold determining method and device. According to the threshold determining method, the reasonable threshold of the communication parameters can be determined by analyzing the historical data of the communication parameters of the cells in different scene types in different time periods. Therefore, based on the threshold value determined by the threshold value determining method provided by the application, the idle time period of a more accurate cell can be determined, and then a corresponding energy-saving strategy can be formulated according to the determined idle time period so as to achieve the purpose of saving energy consumption.
The threshold determining method provided by the embodiment of the application can be applied to a threshold determining device, and the threshold determining device can be a physical machine (such as a server) or a Virtual Machine (VM) deployed on the physical machine. In an exemplary embodiment, when the threshold determining method provided in the embodiment of the present application is executed by a server, the server may be one server or may be a server cluster formed by a plurality of servers, which is not limited in the embodiment of the present application.
Referring to fig. 1, the threshold determining method provided by the embodiment of the application includes:
s101, determining the scene type of the target cell by the threshold determining device.
Wherein, the scene type is the attribution scene under the cell coverage area, and the communication parameters of the cells under different scene types are generally different. By way of example, scene types may include commercial, residential, scenic, junction, school, and the like types.
In addition, the scene type corresponds to a preset period of time. The preset time period in the embodiment of the application is a time period determined by human beings in advance, and the preset time periods of the cells with different scene types can be different. Illustratively, when the scene type is a commercial area, the preset time period is 10 pm to 6 am the next day; when the scene type is Jing Oushi, the preset time period is 8 pm to 5 am in the next day; when the scene type is a residential area, the preset time period is 12 a.m. to 6 a.m.. It can be appreciated that in practical application, the preset time period can be adjusted at any time according to practical situations.
In one possible implementation, the threshold determining means may determine the scene type based on initial station building information of the target cell.
It should be noted that, the cell referred to in the embodiment of the present application may be understood as an area covered by one base station, or may be understood as a sub-area obtained by dividing an area covered by a certain base station according to a certain rule. The specific partitioning rule may refer to descriptions of related content in the prior art, and the embodiments of the present application are not described herein again.
When the cell is an area covered by one base station, the threshold determining device can determine the scene type of the target cell according to the initial station building information of the base station corresponding to the target cell. When the cell is a subarea obtained by dividing the area covered by a certain base station according to a certain rule, the threshold determining device can determine the scene type of the target cell according to the initial station establishment information of the base station to which the subarea corresponding to the target cell belongs.
S102, the threshold determining device acquires historical data of communication parameters of the target cell in a preset time period.
It can be seen that, the preset time period in the embodiment of the present application is an idle period that is preliminarily determined manually according to experience, and after determining the preset time period according to the scene type of the cell, the threshold determining device may analyze the historical data of the communication parameter in the preset time period to determine the threshold of the reliable communication parameter, so that the idle period of the target cell more accurately than the preset time period may be determined according to the threshold of the communication parameter.
Alternatively, the communication parameter may be any one of a physical resource block (physical resource block, PRB) utilization, a Control Channel (CC) utilization, a radio utilization, traffic, and buffer data.
The PRB utilization rate, the CC utilization rate and the wireless utilization rate represent the utilization rate of the target cell to the communication resource in a preset time period. It can be appreciated that in practical applications, the communication parameter may be other parameters for indicating the utilization rate of the communication resource by the target cell in the preset time period. The PRB utilization may be an uplink PRB utilization or a downlink PRB utilization. The CC utilization may be an uplink CC utilization or a downlink CC utilization. The wireless utilization rate may specifically be a utilization rate of the bandwidth by the target cell in a preset time period. The traffic may be the number of users of the target cell within a preset time period. The traffic may be data traffic of all users of the target cell within a preset time period. The buffer data amount may be a downlink buffer data amount or a downlink buffer data amount, which is used to represent the data amount storable in the preset time period by the target cell.
S103, the threshold determining device determines the threshold of the communication parameter according to the historical data.
The historical data acquired by the threshold determining device may be a granularity unit taking a natural day as acquisition data, that is, the communication parameters of the acquisition target cell in each natural day corresponding to a preset time period. Of course, the historical data acquired by the threshold determining device may be granularity units with other interval durations as acquired data. For example, taking a preset time period from 12 a.m. to 6 a.m. as an example, the granularity unit of the collected data may be 1 hour, that is, between 12 a.m. and 6 a.m., the communication parameters are collected every 1 hour.
In addition, taking the example that the threshold determining device collects the communication parameters once every 1 hour, the data collected by the threshold determining device may be an average value of the corresponding communication parameters within 1 hour, or may be a weighted average value of the communication parameters within 1 hour.
In one possible implementation, the threshold determining device may determine the probability distribution of the history data first, and then determine the threshold of the communication parameter according to the probability distribution.
In one possible implementation, the process of determining the threshold of the communication parameter according to the probability distribution may include: the threshold determining means may determine a cumulative distribution function curve of the history data based on the probability distribution of the history data, and determine the threshold of the communication parameter based on the cumulative distribution function curve.
Taking the PRB utilization as an example, the threshold determining device may acquire the historical data with 1 hour as a granularity unit of the acquired data, and then perform data statistics on the acquired historical data to determine a probability distribution of the historical data, so as to obtain the cumulative distribution function curve shown in fig. 2. As shown in fig. 2, the abscissa of the cumulative distribution function curve is the PRB utilization, and the ordinate is the probability, and it can be seen that when the PRB utilization is 1.3%, the probability reaches 0.9, and the PRB utilization of most of the historical data is 1.3% or less, so that 1.3% can be used as the threshold value of the PRB utilization. Of course, in practical applications, the PRB utilization corresponding to the probability of 0.95 (i.e., 2.5%) may be used as the threshold value of the PRB utilization.
Alternatively, after determining the threshold of the communication parameter, the idle period of the target cell may be determined according to the threshold of the communication parameter. For example, if 1.3% is used as the threshold of the PRB utilization, if the PRB utilization is less than 1.3% in a certain period, the period may be determined as the idle period.
In the method for determining the threshold value provided by the embodiment of the application, since the communication parameters can represent whether the cell is in the idle period (taking the traffic of the cell as an example, when the traffic of the cell in a certain time period is low, the time period is the idle period of the cell), and the communication parameters of the cell in different scene types in different time periods are different, the threshold value of the communication parameters can be determined more reasonably by analyzing the historical data of the communication parameters in the preset time period corresponding to the scene type of the target cell. Therefore, based on the threshold determined by the threshold determining method provided by the application, the idle period of the cell can be determined more accurately.
In summary, as shown in fig. 3, step S101 in fig. 1 may be replaced by S1011:
s1011, the threshold determining device determines the scene type according to the initial station building information of the target cell.
Alternatively, as shown in fig. 4, step S103 in fig. 1 may be replaced with S1031-S1032:
