As shown in FIG. 3, the data extraction process of the exchange data analysis and computerization method according to the present invention is first collected from the raw data files outputted from the exchanges 11 and 12 in the RNMS 16. After confirming the collection date by reading the file storing the date of the data to be performed (301), a data extraction cell script (Shell Script) for each type is executed to extract various data necessary for the maintenance and operation of the exchange (302).

That is, the Local Network Management System (RNMS) 16 opens the extraction target source file of the system collection source data storage directory for each model accommodated by the RNMS collection system to read the data and read the data according to the file reading result. Determine whether it is necessary data for analysis and write the necessary data in each extraction file.

Thereafter, the extracted model-specific data is compressed into a single file (303), and the model-specific compressed data accommodated in the collection system is again grouped into a single file and stored in a back-up directory (304). In operation 305, the backed up data is interlocked with the OMS 17.

That is, in order to transfer the extracted files to the OMAS 17, the files are bundled into one file for each model and compressed, and then the files are collected into a single file for each collection system. To the specified directory.

Jobs as described above are automatically registered after being registered in a cron file every day after 0:00. For example, Daegu headquarters is configured to analyze the data of the day by interlocking the data every two hours at the request of users.

In the above process, the local network management apparatus (RNMS) 16 will be described in more detail the process of extracting the necessary data from the raw collection file as follows.

For example, type XX reads a file in which each telephone station system name of type XX is stored and opens a collection source file in a directory where raw data of the corresponding system is stored.

After reading the data, find out if it is necessary for analysis and save it as a file if necessary. For example, if the alarm data is stored in the "alarm.mXX File", if the fault is "Fault.mXX", it is stored in the form of each data that can be divided into each data such as a database.

Next, extract the data of all systems of the corresponding model, and then compress several extract files into one by using a command.

4 is a detailed flowchart illustrating a process of constructing a database of extracted data in a data exchange and computerization method according to an embodiment of the present invention. The operation preservation performance management apparatus (OMAS) 17 is a local network management apparatus (RNMS). (16) shows the procedure to build a database of various data necessary for maintenance and operation maintenance of the exchange.

As shown in Figure 4, the process of building the data extracted from the exchange data analysis and computerization method according to the present invention as a database, by checking the existence of the interlocking data in the operation maintenance performance management apparatus (OMAS) (17) In operation 401, if the linked file exists, one linked file is unpacked and decompressed to obtain an extracted file for each type (402). Here, the reason for bundling and compressing multiple files and then uncompressing them is to save file transfer time between systems.

After that, a detailed detail database is first constructed in a database designed for each model, and the data for NSPMP analysis, CGA (carrier group alarm, transmission line alarm) analysis, and journal writing are calculated from the detailed detail database. Build a database of (404).

This program provides various data related to the exchange maintenance and operation maintenance to the users through the program for various output reports in the database. At this time, the program for various output report (Report) can be changed and added at the request of users according to the change of the operating environment.

A detailed detail database is first constructed in a database designed for each model, and then, NSPMP analysis data, CGA (carrier group alarm, transmission line alarm) analysis data, journal writing data, etc. are calculated from the detailed detail database. The process of building a database is explained in more detail.

Operational preservation performance management unit (OMAS) (17) determines whether transmission data files for each collection system of the regional network management system (RNMS) (16) is transmitted, and if there is an interlocking data file, it is executed by executing a data building program for each model. In constructing detailed DB by model by program, extract data according to DB design of each model and each designed DB structure is constructed. At this time, in case of Alarm and Fault in detail DB construction, search for data without recovery time among the data constructed to build alarm recovery data and compare it with the alarm recovery data extracted The recovery data is constructed, and the detailed time DB is established by calculating the time frame that was not collected by checking the exchange time of collecting the raw data needed for NSPMP calculation.

After that, the most detailed time is calculated by calculating the highest number of occurrences in each system for the type of system for the e-Exchanger operation level analysis. In this case, in order to expedite the output of the analysis of the operation level of the electronic exchange in the detailed DB for NSPMP, the number of occurrences of each item is calculated for each type of system to build a summary DB for NSPMP. In addition, it extracts data related to the exchange operation log from the detailed history DB for NSPMP by the model time, and builds it as a log related DB, and designs a DB for operation data not included in the exchange collection data among the data related to the exchange operation log. Operators input by written input program and build relevant DB.

On the other hand, by extracting the CGA from the built-up alarm DB for each model, build the alarm occurrence location for the CGA analysis DB, and build the CGA alarm DB. At this time, the CGA construction information DB designed to exclude the alarms related to the construction and transmission line test among the CGA alerts stored in the constructed CGA alert DB, and the construction information entered and constructed by the program that inputs the relevant construction at the telephone company CGA alarm is deleted from the CGA alarm DB, and the deleted CGA alarm is constructed as a separate DB (ie, CGA occurrence location DB).

Here, the CGA occurrence location / transmission path DB inputted by the program inputting the transmission path corresponding to the location established in the constructed CGA occurrence location DB is compared with the generated CGA alarm DB to calculate the daily CGA failure, thereby The operator provides a program to input the cause, facility, and repair history of the CGA failure to build a CGA troubleshooting database.

The Operational Preservation Performance Management System (OMAS) 17 provides the menu items for the headquarters and the headquarters with output menu items consisting of programs for outputting the data of the detailed DB and various analysis DBs thus constructed. .

The present invention as described above, by providing a variety of analysis data necessary for maintenance to the exchange operator to support the quick and efficient exchange maintenance work, the rationalization of statistical data management by computerization of various reporting tasks that were dependent on manual work It can reduce time and manpower waste, and revitalize conservation work with reliable data analysis and systematic statistical data management. In addition, by centralizing the data analyzed by each operating station, the computerized processing of preservation work can be done quickly and efficiently by collectively processing station, operation level diagnosis, quality calculation basic data, statistical data report, daily / monthly report data, and operation log using reliable data. Can be done.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

As described above, the present invention can efficiently analyze daily / monthly alarm (ALARM), failure (FAULT) messages, etc. in the telephone station in performing maintenance and operation maintenance of the electronic exchange, and operate the main alarm and failure in the exchange. It can be used as basic data to analyze the special maintenance and exchange operation level by calculating each level item, and computerize tasks such as daily work log preparation to save the time required for other business side work, so By reducing the load and computerizing the reporting system, it is possible to activate the work of the telephone company and the headquarters and contribute to improving the call quality service to customers.
