Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The data synchronization method of the digital twin model provided by the embodiment of the application can be applied to an application environment shown in fig. 1. The terminal is connected with the network element equipment and the digital twin model through the network respectively. The terminal may obtain network element data of the network element device and twin data of the digital twin model. The terminal determines whether the network element data and the twin data need to be segmented or not through counting the data quantity of the network element data and the twin data, and further the terminal determines the data segment needing to be synchronized based on the segmented data segment through comparing the abstract result of the data segment of the network element data and the data segment of the twin data, and further synchronizes the network element data and the twin data. The terminal 102 may be, but is not limited to, a variety of personal computers, notebook computers, and tablet computers.
In one embodiment, as shown in fig. 2, a data synchronization method of a digital twin model is provided, and the method is applied to the terminal in fig. 1 for illustration, and includes the following steps:
step S202, obtaining network element data of the network element equipment and twin data of a digital twin model corresponding to the network element equipment.
The network element equipment can be a network element in a 5G communication network, and the network element consists of one or more machine discs or machine frames and can independently complete certain transmission functions. In operation, the network element device may generate corresponding network element data. Wherein the network element data may be data of network elements in the physical world. And the physical network element corresponds to a corresponding digital twin model. The digital twin model may be a real-time virtual mapping of the network element devices described above. The digital twin model is correspondingly provided with twin data, so that the synchronization of the twin data and the network element data is required to be ensured for managing and monitoring the physical network element through the digital twin model.
Wherein, the network element equipment can have association relation with the digital twin model. In synchronization, the terminal may acquire network element data of the network element device and twin data of a digital twin model corresponding to the network element device. For example, the terminal acquires the network element data and the twin data after receiving the instruction issued by the staff, or the terminal acquires the network element data and the twin data according to a set period. The network element data and the twin data acquired by the terminal may be data that needs to be synchronized.
The terminal can obtain the network element data and the twin data after preprocessing the original data. For example, in one embodiment, the terminal may obtain the original network element data of the network element device, and perform normalization and normalization processing on the original network element data to obtain the network element data.
In addition, when the data amount of the network element data is too large, the terminal can segment the network element data. The terminal can sort the network element data and then segment the network element data. For example, in one embodiment, the terminal may sort the network element data of the network element device according to the data type to segment based on the sorted network element data. The data types may include, but are not limited to, data primary keys, business primary keys, and the like. The sorting position of each type of data can be set according to actual conditions. The twin data may be already ordered data.
Step S204, segmenting the network element data and the twin data to obtain a plurality of first data segments corresponding to the network element data and a plurality of second data segments corresponding to the twin data under the condition that the data volume of the network element data is different from the data volume of the twin data and the data volume of the network element data is larger than a preset data volume threshold.
Wherein, because the network element data is continuously changed, the data amounts of the network element data and the corresponding twin data may be the same or different. For network element data with different data volumes, the terminal can adopt different synchronization modes. For example, the terminal may segment the network element data and the twin data when detecting that the data amounts of the network element data and the twin data are different and that the data amount of the network element data is greater than a preset data amount threshold. For example, the terminal segments according to a preset data segmentation rule to obtain a plurality of first data segments corresponding to the network element data and a plurality of second data segments corresponding to the twin data.
The preset data segmentation rule can be formulated according to service data characteristics of network element data. For example, in one embodiment, the terminal may segment the network element data and its corresponding twin data based on a dichotomy, respectively. In addition, in one embodiment, the terminal may also obtain historical data change information of each data in the network element data during segmentation. The historical data change information indicates that data with a data change rate greater than a preset change rate threshold value, namely data which is changed frequently, in the historical network element data corresponding to the network element data.
The terminal can determine a first change data segment and a first fixed data segment according to the historical data change information, and extract the first change data segment in the network element data. Wherein the first change data segment indicates a data segment having data change information, for example, data having a data change rate greater than or equal to a preset change rate threshold; the first fixed data segment represents a data segment in which data does not change in the historical network element data. Because the network element data and the twin data can be the second change data segment in the corresponding twin data according to the position of the first change data segment in the network element data through the sequencing terminal. The terminal can determine a plurality of first data segments according to the first change data segments and a plurality of second data segments according to the second change data segments. For example, the first variable data segment of the terminal is divided into a plurality of data segments with the same size to obtain a plurality of first data segments, and the second variable data segment is divided into a plurality of data segments with the same size to obtain a plurality of second data segments. In addition, in some embodiments, the terminal may also use the first variable data segment as the first data segment and the second variable data segment as the second data segment. Namely, the terminal can realize data segmentation by distinguishing an invariable data part from a data part which is changed frequently in the network element data.
Step S206, obtaining a first summary result of each first data segment and a second summary result of each corresponding second data segment.
Wherein each of the first data segment and the corresponding second data segment may be data segments of the same data amount. When the data amounts of the first data segment and the second data segment are the same, it is indicated that the two data segments may be the same data segment. At this time, the terminal may detect the data difference between the two data segments through a digest algorithm. Wherein the summary algorithm represents converting data of any length into a data string of fixed length by a preset function. For example, the terminal may convert the network element data and the twin data according to a summarization algorithm to obtain a first summarization result of each first data segment and a second summarization result of each second data segment corresponding to each first data segment. The first data segment corresponds to the first abstract result one by one, and the second data segment corresponds to the second abstract result one by one.
Step S208, determining a first data segment to be synchronized and a corresponding second data segment to be synchronized according to the comparison result of each first abstract result and the corresponding second abstract result, and carrying out data synchronization on the first data segment to be synchronized and the second data segment to be synchronized.
After obtaining the first summary result of each first data segment and the second summary result of each second data segment, the terminal may compare each first summary result with each second summary result to obtain a corresponding comparison result. The terminal can determine the first data segment to be synchronized and the corresponding second data segment to be synchronized according to the comparison result of the first abstract comparison result and the second abstract comparison result. For example, when the first summary result and the second summary result are different, it is indicated that there is a difference between the data of the first data segment corresponding to the first summary result and the data of the second data segment corresponding to the second summary result. At this time, the terminal may further determine, for example, whether the data size of the first data segment and the second data segment with the difference is too large, and if the data size is too large, for example, greater than the preset data size threshold, further segmentation is required, and then comparison of the summary results is performed. If the data size is smaller, for example, smaller than or equal to the preset data size threshold, the terminal may determine that the first data segment is the first data segment to be synchronized, and determine that the second data segment is the second data segment to be synchronized.
Therefore, the terminal can synchronize the data aiming at the first data segment to be synchronized and the second data segment to be synchronized which have data differences, and the terminal can synchronize the plurality of first data segments to be synchronized and the plurality of second data segments to be synchronized, so that the synchronization of the network element data and the twin data is realized.
And when the terminal detects that the first abstract result and the second abstract result are the same, the terminal can also determine that the data of the corresponding first data segment and the corresponding second data segment are the same. For example, in one embodiment, for each first data segment and corresponding second data segment, if the terminal detects that the first summary result of the first data segment is the same as the second summary result of the corresponding second data segment, and the data amounts of the first data segment and the second data segment are the same, which indicates that the data of the first data segment and the second data segment are the same, the terminal may determine that the first data segment and the corresponding second data segment are completed synchronously.
According to the data synchronization method of the digital twin model, when the data amount of the network element data is different from that of twin data of the digital twin model and the data amount of the network element data is larger than the preset data amount threshold, the network element data and the twin data are segmented, a first abstract result of each first data segment corresponding to the segmented network element data and a second abstract result of each second data segment corresponding to the twin data are obtained, and according to a comparison result of the two abstract results, the first data segment to be synchronized and the second data segment to be synchronized are determined, and data synchronization is carried out on the first data segment to be synchronized and the second data segment to be synchronized. Compared with the traditional synchronization based on the full data, the scheme determines the data segment to be synchronized by comparing the segmentation and the abstract result of the data, and then the synchronization is performed based on the data segment, so that the time spent for the synchronization is reduced, and the real-time performance of the synchronization is improved.
In one embodiment, determining the first data segment to be synchronized and the corresponding second data segment to be synchronized according to the comparison result of each first summary result and each corresponding second summary result includes: for each first data segment and the corresponding second data segment, if the comparison result is that the first summary result of the first data segment is different from the second summary result of the corresponding second data segment, and the data volume of the first data segment and the data volume of the corresponding second data segment are smaller than a preset data volume threshold, determining that the first data segment is the first data segment to be synchronized, and determining that the second data segment is the second data segment to be synchronized.
In this embodiment, the terminal may determine the first data segment to be synchronized and the second data segment to be synchronized according to the comparison result of the first summary result and the second summary result and in combination with the data amounts of the corresponding first data segment and second data segment. For example, for each first data segment and each corresponding second data segment. The terminal may further detect whether the data size of the first data segment is smaller than a preset data size threshold and whether the data size of the second data segment is smaller than the preset data size threshold when detecting that the comparison result is that the first summary result of the first data segment is different from the second summary result of the corresponding second data segment. If the first data segment is smaller than the preset data quantity threshold, the terminal can determine that the first data segment is the first data segment to be synchronized, and determine that the second data segment is the second data segment to be synchronized. That is, when there is a data difference in the data segments and the data amount of the data segments is small, the terminal may determine that the data segments are not further segmented, so that the data segments are synchronized as the data segments to be synchronized.
Through the embodiment, the terminal can combine the abstract result and the data quantity of the data segments to determine the data segments to be synchronized, so that the data synchronization is performed based on the data segments to be synchronized, and the real-time performance of network element data synchronization is improved.
In one embodiment, determining the first data segment to be synchronized and the corresponding second data segment to be synchronized according to the comparison result of each first summary result and each corresponding second summary result includes: and if the comparison result is that the first summary result of the first data segment is different from the second summary result of the corresponding second data segment, and the data quantity of the first data segment or the data quantity of the corresponding second data segment is greater than or equal to a preset data quantity threshold value, segmenting the first data segment and the corresponding second data segment again to obtain a plurality of new first data segments and a plurality of new second data segments, and returning to the step of acquiring the first summary result of each first data segment and the second summary result of each corresponding second data segment.
In this embodiment, the terminal may determine the first data segment to be synchronized and the second data segment to be synchronized according to the comparison result of the first summary result and the second summary result and in combination with the data amounts of the corresponding first data segment and second data segment. For example, for each first data segment and each corresponding second data segment. The terminal may further detect whether the data size of the first data segment is greater than a preset data size threshold when detecting that the comparison result is that the first summary result of the first data segment is different from the second summary result of the corresponding second data segment, if the terminal detects that the data size of the first data segment is greater than or equal to the preset data size threshold, or if the terminal detects that the data size of the second data segment corresponding to the first data segment is greater than or equal to the preset data size threshold, it indicates that the data size of the first data segment or the second data segment is too large, and at this time, the terminal may segment the first data segment and the corresponding second data segment again. For example, the segments are performed according to the preset data segment rule, so as to obtain a new plurality of first data segments and a new plurality of second data segments.
After obtaining the new first data segments and the new second data segments, the terminal can return to the step of obtaining the first summary result of each first data segment and the second summary result of each corresponding second data segment, so that the terminal can compare the summary results again based on the new first summary result of the new first data segment and the new second summary result of the new second data segment. The number of the segments may be multiple times until the new first data segment and the new second data segment after the segments are smaller than a preset data amount threshold, where the terminal may respectively use the new first data segment and the new second data segment with different summary results as the first data segment to be synchronized and the second data segment to be synchronized.
Through the embodiment, the terminal can combine the abstract result and the data quantity of the data segments to determine the data segments to be synchronized, and when the data quantity is too large and the abstract result is different, the terminal performs further segmentation and then performs comparison of the abstract result to determine the data segments to be synchronized. And further, data synchronization is performed based on the data segments to be synchronized, so that the real-time performance of network element data synchronization is improved.
In one embodiment, after obtaining the network element data of the network element device and the twin data of the digital twin model corresponding to the network element device, the method further includes: if the data quantity of the network element data and the corresponding twin data are smaller than the preset data quantity threshold, carrying out data synchronization on the network element data and the twin data according to the difference data of the network element data and the twin data.
In this embodiment, after the terminal obtains the overall network element data and the twin data, the data amount may be compared first. If the terminal detects that the data quantity of the network element data and the corresponding twin data are smaller than the preset data quantity threshold, the terminal indicates that the overall data quantity of the network element data is smaller, at the moment, the terminal can directly acquire the difference data of the network element data and the twin data, and data synchronization is carried out on the network element data and the twin data according to the difference data. Therefore, when the data quantity of the network element data and the twin data is smaller, the terminal directly synchronizes the network element data and the twin data in a one-by-one comparison mode based on the difference data.
Through the embodiment, the terminal can synchronize the network element data and the twin data through the difference data when the overall data volume of the network element data and the twin data is smaller, so that the real-time performance of the network element data synchronization is improved.
In one embodiment, data synchronization is performed for a first data segment to be synchronized and a second data segment to be synchronized, including: if the first data segment to be synchronized is smaller than a preset data quantity threshold value, acquiring difference data of the first data segment to be synchronized and the corresponding second data segment to be synchronized; and updating the second data segment to be synchronized according to the difference data to obtain a synchronization result.
In this embodiment, after the terminal segments the network element data and the twin data, a first data segment to be synchronized and a second data segment to be synchronized may be obtained. The terminal may segment multiple times until the first data segment to be synchronized and the second data segment to be synchronized are less than a preset data amount threshold. Namely, when the terminal detects that the first data segment to be synchronized and the second data segment to be synchronized are smaller than a preset data quantity threshold value under the condition that the data quantity of the first data segment to be synchronized and the second data segment to be synchronized are the same and the summary result is different, the terminal can acquire difference data of the first data segment to be synchronized and the corresponding second data segment to be synchronized.
The terminal may update the second data segment to be synchronized based on the difference data between the first data segment to be synchronized and the second data segment to be synchronized, for example, delete and improve corresponding data, and obtain the synchronization result of the data segment based on the updated second data segment. The terminal can update the first data segment to be synchronized and the second data segment to be synchronized by comparing difference data one by one. The terminal can obtain the synchronization result of the network element data and the twin data through the synchronization result of the first data segment to be synchronized and the second data segment to be synchronized.
Through the embodiment, the terminal can synchronize the data segments through the difference data when the data volume of the first data segment to be synchronized and the second data segment to be synchronized is smaller, so that the real-time performance of network element data synchronization is improved.
In one embodiment, as shown in fig. 3, fig. 3 is a flow chart of a data synchronization method of a digital twin model in another embodiment. In this embodiment, the terminal may collect network element data that needs to be synchronized by the physical network element device, and determine whether the data amounts of the network element data and the corresponding twin data are the same. When the data amounts are different, the difference exists between the two data.
The terminal may determine whether the data amounts of the two are larger, for example, whether the data amount is larger than a preset data amount threshold. If yes, the terminal can segment according to a preset data segmentation rule. And the terminal can compare the abstract results of the two corresponding data segments until the data quantity of the network element data and the twin data in the corresponding data segments is the same. When the terminal detects that the data quantity of the corresponding two data segments is smaller than a preset data quantity threshold value, the terminal can directly realize data synchronization through one-by-one comparison. For example by synchronizing the first data segment and the second data segment by means of differential data as described above, or by synchronizing network element data and twinning data.
When the terminal detects that the data amounts of the two corresponding data segments are the same, the data of the data segments indicating the network element data and the data segments of the twin data may be the same. The two data segments may be the first data segment to be synchronized and the second data segment to be synchronized. At this time, the terminal can convert the data in the data segment through the summarization algorithm, compare the summarization result of the data segment of the network element data with the summarization result of the data segment of the twin data, and when the terminal detects that the two summarization results are identical, the terminal can determine that the twin data is identical with the data in the data segment corresponding to the network element data respectively, and the segment data is synchronized.
When the summary results are different and the data volume in the two data segments is larger than the preset data volume threshold, the terminal can return to the step of segmenting the data according to the segmentation rule, and compare the summary results again according to the segmented data segments until the data volumes of the two segmented data segments are smaller than the preset data volume threshold, and synchronization is realized in a one-by-one comparison mode when the summary results are different; or, the data quantity of the two segmented data segments is larger than or equal to a preset data quantity threshold value, but the abstract results are the same, which indicates that the two data segments are identical, and the data segments are synchronized.
Through the embodiment, the terminal determines the data segment to be synchronized by comparing the segmentation and the summary results of the data, so that the synchronization is performed based on the data segment, the time spent for the synchronization is reduced, and the real-time performance of the synchronization is improved. And the terminal combines the data and the service characteristics, so as to purposefully optimize the data segmentation logic, such as making segmentation rules for intervals where the data can not be changed or is less changed and is frequently changed, or segmenting by using a more general dichotomy, adapt to different service scene data, and purposefully improve the synchronization efficiency.
And the terminal only needs to process the network element data, does not need to acquire operation logs and other operations, reduces dependence on related authorities, is insensitive to information such as manufacturers and network element types and has good universality and expandability. In addition, through the scheme, the data synchronization efficiency and the network perception capability can be effectively improved, the instantaneity of the twin model is improved, and an effective solution is provided for synchronization of a large amount of network element data of different services. For example, the real-time performance of the digital twin model can be improved, the actual application of the digital twin model in a communication network is supported, and the application of the digital twin technology in more scenes with higher real-time requirements is promoted; and network element data of common factories and network element types of the existing network can be matched, so that the efficiency of the digital twin technology of the communication network is improved, and the intelligent level of the communication network is promoted.
