Description
Technical Field
The present invention relates to the field of MSAN devices, and in particular, to a data backup and configuration method, device, storage medium, and system.
Background
Generally, a communication carrier in a country divides the country into a plurality of areas, and each area has a plurality of MSAN (Multi-Service Access Node ) devices, and a network management system for managing all MSAN devices is set. In general, the number of MSAN devices that a network management system needs to manage is very large, for example, the number of MSAN devices that a network management system set by a certain communication carrier manages is up to 5000.
The communication carrier sets a corresponding number analysis table file for each of the areas, and all MSAN devices under each of the areas store the number analysis table file corresponding to the area, which is stored in a service database (Sysconfig) of the MSAN devices. In this way, in the operation process of all MSAN devices, if a user dials a correct number, the MSAN device will perform number analysis on the number according to the number analysis table file, determine the network addressing and service processing mode corresponding to the number, and perform signaling interaction and session connection correctly, so as to realize the call between the user and the terminal to which the dialed number belongs. However, various faults can occur in the running process of the MSAN device inevitably, the device is restarted if the faults are light, and the data loss occurs if the faults are heavy, so that the MSAN device needs to be subjected to data configuration again after the faults are removed. Therefore, in order to prevent data loss, it is very important to regularly backup the service databases of all MSAN devices through the network management system.
However, since the number analysis table file has a very large record size, the size of the number analysis table file is very large, and thus the service database is very large, for example, a size of 14.9M of the number analysis table file storing 20 ten thousand records is very large, and thus the service database is very large 15M. Thus, when the network management system performs data backup on all MSAN devices, the required traffic will be quite large, for example, the traffic spent by the network management system in performing data backup is as high as 75G (15 m×5000), which is obviously completely unacceptable. Therefore, it can be seen that based on the MSAN device, an effective data backup and configuration method is needed, which not only can greatly reduce the volume of the service database of the MSAN device, thereby greatly reducing the data backup flow of the network management system, but also can successfully configure the MSAN device according to the service database with greatly reduced volume when the MSAN device performs data configuration.
Accordingly, there is a need for improvement and development in the art.

Detailed Description
The invention provides a data backup and configuration method, equipment, a storage medium and a system, which are used for making the purposes, technical schemes and effects of the invention clearer and more definite, and the invention is further described in detail below. 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 invention.
In a first aspect, referring to fig. 1, a data backup and configuration method provided by the present invention includes the steps of:
s10, reading a number analysis list file stored in a service database, saving the number analysis list file to another storage space, and deleting the number analysis list file in the service database;
specifically, in the service database of the MSAN device, the volume occupied by the number analysis table file is very large in general, for example, in the MSAN device described in the background art, the volume of the service database is 15M, and the volume of the number analysis table file reaches 14.9M, so if the number analysis table file in the service database is stripped, the volume of the service database can be greatly reduced, and then the flow required when the network management system performs data backup on all the MSAN devices managed by the network management system is greatly reduced.
Based on the above thought, after the number analysis table file stored in the service database is read, the number analysis table file is stored in a storage space except the service database, and the number analysis table file is deleted in the service database, the service database does not contain the number analysis table file any more, so that the volume of the service database is greatly reduced. Preferably, in the storing process, the stored file is named according to a designated name, for example, number Anylasis.
In one embodiment, step S10 is preceded by:
s001, screening all files with appointed suffixes from the service database;
specifically, as shown in fig. 2, the service database contains a number of files with specified suffixes, which are typically binary files ending with cfg, and the number analysis table file is also binary file ending with cfg. Therefore, it is necessary to filter out all files ending with cfg and further look up the number analysis table file in these files.
S002, reading the file with the largest file volume from all the files with the specified suffixes;
s003, judging whether the content in the file with the largest file volume contains specific characteristic content, if so, judging that the file with the largest file volume is a number analysis table file.
In particular, the volume ratio of the number analysis table file is usually the largest in the traffic database, so that the largest file among all files ending with cfg can be basically confirmed as the number analysis table file, but for the reliability of the scheme, it is further verified whether the largest file is the number analysis table file.
Therefore, firstly, the file with the largest volume is read, whether the content of the file contains specific characteristic content or not is judged, and if so, the file is judged to be a number analysis table file. The content of the number analysis table file is standard and fixed, and the standard and fixed content is specific feature content, and the specific feature content is related to the planning of the operator where the MSAN device is located, as shown in fig. 3, the specific feature content includes one or more of OFC code, number prefix, minimum number length, maximum number length and processing index code. Therefore, the file with the largest volume and ending with cfg is read first, and whether the content of the file contains specific characteristic content or not is judged, so that whether the file is a number analysis table file or not is judged, the execution efficiency of the whole method is improved, and the reliability of the whole method is also improved.
In another embodiment, step S003 further comprises:
s004, if not, sequentially reading the rest files with the specified suffixes according to the sequence from big to small of the file volume, judging whether the content of the currently read file contains the specific characteristic content, and if so, judging that the currently read file is a number analysis table file.
In particular, it is not excluded that some special cases (e.g. human errors) result in that the cfg file with the largest volume in the service data is not the number analysis table file, so in order to further ensure the reliability of the method as a whole, if step S003 determines that the content of the cfg file with the largest volume does not contain specific feature content, it is determined that the cfg file with the largest volume is not the number analysis table file, and thus it is necessary to continue to identify the number analysis table file in the remaining cfg files.
Based on the characteristics of the number analysis table file, sequentially reading the rest files ending with cfg according to the sequence from large to small in volume, judging whether the content of the file currently read contains specific characteristic content or not after reading, and if yes, judging that the file currently read is the number analysis table file; if not, continuing to read the next file and continuing to judge until the content of a certain file is read to contain specific characteristic content.
And S20, when a data backup instruction sent by the network management system is received, the service database of the deleted number analysis table file is sent to the network management system for backup.
Specifically, after step S10, the service database of the MSAN device has no number analysis table file, and the number analysis table file is stored in a storage space of the MSAN device except for the service database, so that the volume of the service database has been greatly reduced, for example, after the number analysis table file is stripped, the volume of the service database of the MSAN device changes from 15M to only 100K (15M-14.9M). Therefore, when the network management system needs to perform data backup on all the MSAN devices managed by the network management system, namely, each MSAN device receives a data backup instruction sent by the network management system, each MSAN device sends the service database to the network management system, and at the moment, even if the number of the MSAN devices is very large, the volume of the service database of each MSAN device is very small, so that the flow required by the network management system for performing data backup is very small. For example, in the network management system and 5000 MSAN devices managed by the network management system in the background technology, the flow required by the original network management system when carrying out data backup is up to 75G, but the volume of the service database of each MSAN device after step S10 is only 100K (original 14.9M), so the flow required by the network management system when carrying out data backup is only about 500MB (100 k×5000), and obviously, the method provided by the invention can greatly reduce the data backup flow of the network management system.
In another embodiment, the data backup and configuration method further includes the steps of:
s30, when a data configuration instruction is received, if the current MSAN equipment is started for the first time, importing a number file table file corresponding to the MSAN equipment from the network management system; and reading a service database in the storage space of the MSAN equipment and a number file table file imported from the network management system to complete data configuration.
And S40, if the current MSAN equipment is not started for the first time, reading a service database and a number analysis table file in the storage space of the MSAN equipment to complete data configuration.
Specifically, when the original MSAN device needs to perform data configuration, the original MSAN device reads the service database in the storage space and writes the service database into the memory, and although the above steps can solve the problem that the network management system has too large flow during data backup, the service database of the MSAN device after the above steps has no number analysis table file, and the original data configuration method is not applicable any more. Based on this, a new data configuration method of the MSAN is required.
When the MSAN device receives the data configuration instruction, if the MSAN device is started for the first time, the MSAN device is indicated to be a new device, and the storage space of the MSAN device is provided with a service database, but no number analysis table file, so that the number analysis table file corresponding to the MSAN device needs to be imported from a network management system, and after the number analysis table file is successfully imported, the MSAN device reads the service database and the number analysis table file and writes the service database and the number analysis table file into a memory to complete data configuration. The data configuration instruction can be sent to the MSAN equipment by a network management system or can be sent by the field operation of related staff; the number analysis table file corresponding to the MSAN device, specifically, each MSAN device has a region to which the MSAN device belongs, and each region corresponds to one number analysis table file, so the number analysis table file corresponding to the MSAN device refers to the number analysis table file corresponding to the region to which the MSAN device belongs.
If the MSAN device is not started for the first time, the MSAN device is not a new device, the service database and the number analysis table file are stored in the storage space of the MSAN device, and the MSAN device directly reads the service database and the number analysis table file and writes the service database and the number analysis table file into the memory to complete data configuration.
In summary, the method for data backup and configuration provided by the invention firstly identifies the number analysis table file in the service database of the MSAN device, then reads the number analysis table file, stores the number analysis table file in another storage space, and deletes the number analysis table file in the service database, so that the volume of the service database can be greatly reduced, and further, the flow required by a network management system for carrying out data backup on all the MSAN devices managed by the network management system is greatly reduced.
In a second aspect, the present invention also provides a storage medium storing a data backup and configuration program, which when executed by a processor implements the steps of any of the data backup and configuration methods, as described above.
In a third aspect, the present invention also provides an MSAN apparatus, including: the system comprises a memory, a processor and a data backup and configuration program stored on the memory and capable of running on the processor, wherein the data backup and configuration program realizes the steps of any data backup and configuration method when being executed by the processor, and the steps are concretely described above.
In a fourth aspect, the present invention further provides a data backup and configuration system, where the data backup and configuration system includes a plurality of MSAN devices according to the third aspect, and a network management system that establishes communication connection with all the MSAN devices, where all the MSAN devices receive, through a wireless network, a data backup or data configuration instruction transmitted by the network management system in real time, and execute a corresponding operation according to the data backup or data configuration instruction, as described above in detail.
It is to be understood that the invention is not limited in its application to the examples described above, but is capable of modification and variation in light of the above teachings by those skilled in the art, and that all such modifications and variations are intended to be included within the scope of the appended claims.
