The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
In the related art, the energy saving state of a cell is often determined according to a preset energy saving parameter value, the preset energy saving parameter configuration is often set only based on the scene classification (for example, scenes of hospitals, factories, schools, and the like) of the cell in the spatial dimension, the granularity of the scene classification is coarse, the configuration precision of the energy saving parameter value is low, the dynamic environment change cannot be adapted, and the energy saving effect is limited.
Based on this, in various embodiments of the present application, a method for performing personalized configuration on an energy saving threshold of a cell based on classification results of the cell in two dimensions, namely time and space, is provided, so that a determined energy saving threshold not only adapts to a scene classification requirement of the cell in the space dimension, but also adapts to a change of user distribution in the time dimension, and thus an energy saving control strategy can be changed based on the change of the user distribution, and an energy saving effect is better.
The embodiment of the present application provides a method for determining an energy saving threshold, which may be applied to a base station, and may also be applied to a network device (for example, an energy saving operation and maintenance platform) in communication connection with the base station, and this is not specifically limited in this application. As shown in fig. 1, the method for determining the energy saving threshold includes:
step 101, obtaining feature data of a current set time length of a target cell, wherein the feature data is used for indicating user distribution of the target cell.
And 102, predicting the characteristic data of the next set time length based on the characteristic data of the current set time length.
And 103, determining a scene state corresponding to the next set time length of the target cell based on the predicted characteristic data and a cell state base which is constructed in advance.
And 104, determining a target energy-saving threshold corresponding to the next set time length of the target cell based on the scene state and a pre-constructed energy-saving threshold library.
In the embodiment of the application, the cell state library includes corresponding scene states determined based on engineering parameters of a cell and historical user distribution, the scene states can indicate a first result of spatial dimension classification corresponding to the cell and a second result of continuous classification based on time dimension on the basis of the spatial dimension classification, and the energy-saving threshold library includes corresponding energy-saving thresholds determined based on historical working parameters under various scene states in the cell state library.
In the embodiment of the application, feature data of the next set time length is predicted based on feature data of the current set time length of a target cell, and a scene state corresponding to the next set time length of the target cell is determined based on the predicted feature data and a pre-constructed cell state library, wherein the scene state can indicate a first result of space dimension classification corresponding to the cell and a second result of continuous classification based on a time dimension on the basis of the space dimension classification, so that the predicted scene state of the target cell is a classification result in the space dimension and the time dimension; and then, a target energy-saving threshold corresponding to the next set time length of the target cell is determined based on the scene state and a pre-constructed energy-saving threshold library, so that the determined target energy-saving threshold can adapt to the change of the user distribution of the target cell based on the time dimension, and further, the energy-saving control strategy can be changed based on the change of the user distribution, and the energy-saving effect is better.
Illustratively, the characteristic data may be MR (Measurement Report) data of the cell. The set time duration may be reasonably set according to the update requirement of the energy saving threshold, for example, the set time duration may be one hour, or may be a time duration longer than or shorter than one hour, which is not specifically limited in this application. The energy saving threshold can be understood as a parameter value for performing energy saving control.
For example, a cell state base and an energy-saving threshold base may be pre-constructed based on an offline algorithm, feature data of a next set time duration of a target cell is predicted based on an online algorithm, and a scene state of the target cell and a corresponding target energy-saving threshold are determined.
Illustratively, the method for determining the energy-saving threshold further comprises:
and clustering to generate the cell state library based on the engineering parameters of the cell and historical user distribution.
Taking the energy-saving threshold determination method applied to the network device as an example, the network device may collect the engineering parameters of the cell and the historical user distribution, and cluster to generate the cell state library.
Illustratively, clustering generates the cell state library based on the engineering parameters and the historical user distribution of the cells, including:
clustering and dividing each cell based on the engineering parameters of the cell to obtain the first result;
clustering and dividing the user distribution of different set durations of the various types of cell histories obtained by dividing the first result to obtain a second result;
determining the scene state based on the first result and the second result.
Here, the engineering parameters of the cell may include index data indicating the coverage of the cell itself, a geographical scenario, for example, including: station height, downward inclination angle, total number of configured adjacent regions, average station spacing, weak coverage and overlapping coverage. And clustering and dividing the engineering parameters of each cell to obtain a first result representing the scene classification of the cells in the spatial dimension. Here, the clustering partition may employ a K-means clustering algorithm (K-means clustering algorithm) so as to perform a first type of partition on the cells based on the engineering parameters of the cells. Illustratively, the results of the first type of partitioning are shown in table 1:
TABLE 1
Cell identity Scene state label
Cell-1 Cluster # scene A
Cell-2 Cluster # scene B
Cell-3 Cluster # scene C
It should be noted that the engineering parameters of the cell may further include: the indexes such as the coverage scene and the building name, that is, the coverage scene, the building name, and the like of each cell may be considered when performing the clustering of the first-class partitions.
Here, on the basis of the first-class partition, clustering partition may be further performed based on the various types of cells of the first-class partition. Illustratively, for the foregoing scenario a, based on the user distribution of different set durations of history, for example, based on the MR data of the small-scale of the cell history, cluster division is performed to obtain categories 1, 2, 3, and 4 … … of the user distribution, and groups optimized in the same kind are obtained comprehensively, for example, a1, a2, A3, a4 … …, B1, B2, B3, B4 … …, and the like.
Illustratively, the scene state determined based on the first and second results is shown in table 2:
TABLE 2
Cell identity User distribution Scene state label
Cell-1 MR1 Cluster # scene A1
Cell-1 MR2 Cluster # scene A2
Cell-1 MR3 Cluster # scene A3
Cell-1 MR4 Cluster # scene A4
As can be seen from table 2, the scene status can indicate a first result of the spatial dimension classification corresponding to the cell and a second result of the continuous classification based on the time dimension on the basis of the spatial dimension classification.
Therefore, the cell state library can be established by performing the joint clustering analysis on the scene of the cell in the space dimension and the user distribution in the time dimension.
Further, in order to implement experience sharing, the energy-saving threshold of the same optimization group (i.e., the same scene state) may be optimized according to the classification result in the cell state library, so as to reduce the amount of computation, and facilitate the online determination of the energy-saving threshold corresponding to each scene state. Based on this, the energy-saving threshold determination method further includes:
determining a corresponding energy-saving threshold based on historical Performance Management (PM) data and Key Performance Indicator (KPI) data of each scene state in the cell state library, and generating the energy-saving threshold library.
Illustratively, the PM data may include: RRC (Radio Resource Control) maximum connection number, uplink traffic, downlink traffic, uplink PRB (Physical Resource Block) utilization, and downlink PRB utilization. Network KPI data may include: RRC establishment success rate, ERAB (Evolved Radio Access Bearer) establishment success rate, Radio Access rate, Radio drop rate, and handover success rate.
Exemplarily, the determining the corresponding energy saving threshold based on the historical PM data and the network KPI data in each scene state in the cell state library includes:
and determining a limit value of the PM data corresponding to the network KPI data and meeting the setting requirement based on the historical PM data and the network KPI data in each scene state in the cell state library, and taking the limit value of the PM data as a corresponding energy-saving threshold.
Here, the limit value of the PM data at which the network KPI data satisfies the setting requirement means: and solving the parameter value of the cell with the network KPI maintained stable and the highest turn-off load threshold (energy saving is most).
Here, for each scene state in the cell state library generated by the clustering, the PM data that keeps the network KPI stable and saves energy most is solved respectively, and is used as the energy-saving threshold corresponding to the corresponding scene state, so as to construct the energy-saving threshold library. Therefore, the cells can be clustered and divided through the scene of the cells and the clustering analysis of the information related to the user distribution, the division of space and time granularity can be obtained, namely the division of a certain cell under certain user distribution, and the corresponding energy-saving threshold is determined aiming at the similar optimized grouping through analyzing the historical PM data and the network KPI data, so that an energy-saving threshold library is formed, and conditions and basis are provided for the later time-space granularity parameter adaptive optimization.
In some embodiments, the highest turn-off load threshold at which the network KPI starts to deteriorate can be solved by numerical analysis for the historical PM data and network KPI data in each scene state in the cell state library, so as to obtain the corresponding energy-saving threshold. Here, the network KPI may start to deteriorate, that is, a variation difference of the network KPI data reaches a set requirement or the network KPI data is lower than a set threshold, which is not limited in the present application.
In some embodiments, the determining, based on the historical PM data and network KPI data in each scene state in the cell state base, a limit value of the PM data corresponding to the network KPI data meeting a set requirement includes:
training an initial model by taking historical PM data and network KPI data in each scene state in the cell state library as training data to obtain a trained model;
and solving the trained model by adopting an optimization search algorithm to obtain the limit value of the PM data corresponding to the network KPI data meeting the set requirement.
Illustratively, a machine learning algorithm is adopted to mine the relationship between the PM data and the network KPI data so as to solve the highest turn-off load threshold of the network KPI starting to deteriorate. The initial model was established as follows:
Y=f(X)
the input data X is PM data (RRC maximum connection number, uplink traffic, downlink traffic, uplink PRB utilization, downlink PRB utilization), and the output data Y is network KPI data (RRC establishment success rate, ERAB establishment success rate, wireless connection rate, wireless disconnection rate, handover success rate) predicted by a function f. Illustratively, the data in the input data X is read in row by row and converted into a column matrix as the input of the neural network, and similarly, the output data Y matrix is converted into a column matrix as the output of the neural network.
Here, the RELU function is used as an activation function in the neural network, the output Y of the regression problem contains a plurality of variables, and the design cost function is:
Figure BDA0002950721050000081
wherein, y i Is sample data, y i ' is the predicted value calculated by the neural network, and l is the number of samples. Namely, the average value of Mean Square Error (MSE) of each variable is used as a loss function, and the cost function of the network is minimized by training the model and adjusting the weight and the bias.
And aiming at the trained model, selecting the highest turn-off load threshold of the network KPI starting to deteriorate by adopting an optimization search algorithm. For example, a genetic algorithm may be employed to search the resulting training model for the highest shutdown load threshold that causes the network KPI to begin deteriorating. Thus, the energy saving threshold corresponding to each scene state can be obtained, which is schematically shown in table 3 below.

Cell-1 MR2 Cluster # scene A2 Parameter combination 2: numerical value

It can be understood that table 3 illustrates an optimal threshold parameter (i.e., an energy saving threshold) corresponding to each optimized group, so as to determine the optimized group to which the cell belongs based on the predicted user distribution of the cell, and further determine the energy saving threshold corresponding to the cell. The optimal threshold parameters corresponding to each optimization group can be constructed off-line, experience sharing is realized, and on-line computation amount can be reduced, so that an on-line part can directly utilize an experience library obtained by off-line computation, the on-line computation amount is greatly reduced, and the deployment of implementation and application is facilitated.
In some embodiments, predicting the feature data of the next set duration based on the feature data of the current set duration comprises: and predicting the feature data of the current set duration based on a Long Short-Term Memory network (LSTM) to obtain the feature data of the next set duration.
Here, the LSTM has a unique memory mode and a forgetting mode, so that the network can sufficiently mine the time-series characteristics of the time-series data, learn the time dependency relationship between the input data, and predict MR data of the next set duration based on the historical MR data of the set duration.
It is understood that, in practical applications, the classification result of the cell in the spatial dimension, that is, the aforementioned first result (scene A, B, C, etc.), may be determined based on the cell identifier, and the scene state corresponding to the next set duration of the cell may be determined based on the predicted MR data. With reference to table 3, assuming that the Cell identifier is determined to be Cell-1, the predicted user distribution falls into MR2, and the scene state label is determined to be a2, then the energy saving threshold corresponding to parameter combination 2 is selected as the target energy saving threshold.
The present application is described in further detail below with reference to application examples.
As shown in fig. 2, in the present application example, the overall flow includes two parts, that is, offline and online: the offline data mining refers to performing joint clustering analysis on the cell scene and the user distribution by using historical data to form a scene and user distribution state base (which is equivalent to the cell state base). According to each division, the relation between the historical energy-saving threshold parameter and the network KPI and the energy consumption is mined, the parameter which keeps the network KPI stable and has the highest turn-off load threshold (the most energy-saving) is solved, and a parameter library (equivalent to the energy-saving threshold library) corresponding to the scene and the user distribution is formed. The online part is to predict the user distribution of the next time granularity of the cell by using real-time cell data, classify the predicted user distribution according to the prediction result, and find out the scene and the user distribution corresponding to the next time of the cell and the energy-saving threshold corresponding to the scene and the user distribution by combining the cell scene information.
Illustratively, the offline part acquires historical network state data (data such as working parameters, PM, network KPI, MR, overlapping coverage scenes and the like), performs preprocessing such as normalization on the acquired data, constructs a scene and user distribution state library based on joint clustering in space dimension and time dimension, establishes a similar optimization group from space granularity and time granularity, can realize experience sharing, and can reduce the computation amount. Based on a scene and user distribution state library, parameter optimization can be performed through modeling and training, for example, a genetic algorithm is adopted to search a highest turn-off load threshold which enables a network KPI to begin to deteriorate in an obtained training model, and an energy-saving threshold corresponding to each scene state is obtained, so that an individualized energy-saving parameter configuration suggestion is obtained.
It can be understood that, along with the existing network test and the accumulation of experience, the scene and user distribution state library and the scene and user distribution parameter library may be continuously updated, for example, updated based on a set period or updated based on an instruction, so as to meet the control requirement of the energy saving strategy corresponding to the new user distribution, thereby implementing the refined energy saving control.
Illustratively, the online portion may predict the user distribution at the next time granularity (such as the hour level) based on the LSTM. For example, the raw data set may be preprocessed to obtain p training set samples, each sampleThere are T MR data of
Figure BDA0002950721050000101
The corresponding label is { y (1) ,y (2) ,...,y (i) ,...,y (p) In which x (i) Which represents the number of the i-th sample,
Figure BDA0002950721050000102
t-th data, y, representing the i-th sample (i) And a label corresponding to the ith sample, namely the predicted MR value of the ith sample at the next moment.
The ith sample x (i) Predicted wireless network MR value y at next time as input to long-short term memory network (i) . Performing a network training on one sample requires T time steps, each time step corresponding to one LSTM cell (LSTM cell). The long-term and short-term memory network adopts a self-circulation method, and only one data can be input into the network at each moment. Illustratively, the historical data and the LSTM model can be used for training the model for predicting 1h in the future every 1h, and the data of the previous 3 hours can be used for predicting the value of 1h in the future. And then, based on the predicted MR data of the next hour, determining the scene type of the target cell in the scene and user distribution state library by combining with the cell identifier, and determining the corresponding target energy-saving threshold based on the energy-saving threshold corresponding to the scene type, so that the base station adjusts the energy-saving strategy based on the newly determined target energy-saving threshold.
