Abstract

The present invention relates to an adaptive network management system that can be used adaptively to environmental changes of a communication network including a change in an output message of an electronic exchange (ESS). In order to analyze the message of the system, it provides the advantage that it can be immediately accepted only by changing the information on the message (modification of data extraction language table and control information file) without additional S / W supplement or additional function development. Due to the expansion, the addition or deletion of network management data to be constructed simply consists of additional calculation calculations for the corresponding items in the data extraction language table or deletion of the calculation expressions for the corresponding items. In addition, it separates S / W and database schema, and finally, a number of conventional processors This has the advantage of simplifying the interior of the network management system by having a single interpreter module instead.

Description

Adaptive Network Management System

The present invention receives on-line message output information on the overall state of the ESS (failure and call statistics, etc.) generated from an electronic switching system (hereinafter referred to as an ESS) constituting a telecommunication network. The present invention relates to a network management system for processing a network, and more particularly, to an adaptive network management system and a method thereof, which can be used adaptively to a change in an environment of a communication network including a change in an output message of an ESS.

In recent years, telecommunication networks have been rapidly expanding facilities and upgrading of functions. And with the advent of the information society, as the role of communication network plays an increasing role in society as a whole, the centralization and automation of communication network operation management is emerging as an essential component of communication network.

In consideration of the importance of network operation management, ITU-T also sets the operation system element as an essential element of communication network as a concept of automation / centralization for communication network.

The network management system is an operation system for operating a communication network in the form of automation / centralization, and because of its characteristics, is connected to various types and / or a plurality of ESS equipment and data communication networks constituting the communication network and various types of data from the ESS. Basically, a function of collecting and accumulating information and processing and processing various communication network management information from these information is provided.

To this end, the network management system essentially performs a function of executing an appropriate process on the output message information from the ESS delivered from the on-line communication module and storing the data in a table of a database. For this function, the current network management system requires the establishment of processes for each database according to the Syntax Forma of ESS output messages.

That is, because the syntax structure of the output message of the ESS is different, the current network management system had to have a number of processors corresponding to the syntax format of the ESS output message.

However, in reality, due to the operational characteristics of the network management system, the type and quantity of output messages of the ESS to be accommodated by the network management system have a variable change factor, and the object to be extracted by the network management system even in one ESS output message. The data field has a change factor that can be changed (from 'A' field to 'B' field).

The existing network management system has a problem in that a data construction process should be added or changed due to a change of a version of an ESS system, a change of a configuration of a communication network, and a change of a communication network operation function.

In fact, the problems of the conventional network management system will be described in detail with reference to FIG.

The conventional network management system shown in FIG. 1 is constructed in a syntax dependent manner depending on the structure of the output message from the ESS. The conventional network management system has an on-line communication module 10 for filtering and receiving messages from the ESS. The on-line communication module 10 stores the messages received from the ESSs in the temporary storage module 12.

The temporary storage module 12 has n buffers B1 to Bn, and the n buffers B1 to Bn store output messages of ESSs having different syntax formats. Each of the buffers B1 to Bn separately stores messages from ESSs connected to the on-line communication module 10. In addition, the n buffers B1 to Bn output messages from the ESSs stored in the database to the database building module 14.

The database building module 14 includes n processors PS1 to PSn connected to the n buffers B1 to Bn, respectively. The n processors PS1 to PSn respectively retrieve messages stored in the buffers B1 to Bn connected thereto and check whether the retrieved messages are in error.

Each of the n processors PS1 to PSn calculates necessary network performance parameters using the extracted messages, and stores the calculated network performance parameters and the raw data included in the extracted messages in a database table module. 16). The database table module 16 includes first and second data tables DT1 and DT2. The first data table DT1 stores the network performance parameters, and the second data table DT2 stores the raw data.

As described above, the conventional network management system implements a data processing loop for each syntax environment of the output message of the ESS, that is, the environment of the communication network, thereby adding and changing functions whenever an environmental change factor of the communication network occurs. do. In addition, when additional output messages of the ESS are required, the conventional network management system is accompanied with an overall performance improvement such as an increase in memory capacity and a processing processor due to an increase in software for processing additional output messages of the ESS. Is holding.

In other words, the existing network management system is limited to a predetermined message format, and thus, even if the exchange type is changed or even the same type of exchange is upgraded, the message format may be changed. You have to change or, moreover, make H / W changes.

In addition, as mentioned above, since the devices (processors) for processing the data are classified according to the types of the network management data, it is not possible to process all the network management data in one device. If you do, you have to develop additional S / W.

The present invention, in order to improve the conventional problems as described above, after receiving all the messages of the exchange input through the channel connected to the online communication module only necessary network management messages (for example, messages about the performance and load of the exchange, Newly added messages and analysis messages, etc.) can be separated and the network management data can be calculated in real time based on the information defined in the data extraction language table from the separated messages, thereby accepting new models or existing existing ESSs to be managed. It is an object of the present invention to provide an adaptive network management system that can be used adaptively to changes in the environment of a communication network, including changes in output messages or changes in form due to the improvement of the ESS, or additional analysis of new network management data.

It features.

The above objects, features, and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 2 through 4.

Referring to FIG. 2, the adaptive network management system according to the embodiment of the present invention is configured to filter and receive output messages from a plurality of ESSs (not shown) via the public telecommunication network 21. A line communication module 20 is provided. The on-line communication module 20 separates only the messages required for network management from all the received messages from the ESSs and stores them in the temporary storage module 22.

The temporary storage module 22 includes n buffers B1 to Bn, and the n buffers B1 to Bn store output messages of ESSs having different syntax formats. Each of the buffers B1 to Bn separates and stores only messages required for network management among all the messages received from the ESSs connected to the on-line communication module 20, and stores them by message. .

The adaptive network management system also stores data extraction language tables describing information for extracting network management data from the exchange output message, and a control information file for retrieving data extraction language tables according to the exchange system. Memory 24 is provided. As shown in FIG. 3, the data extraction language table is composed of six blocks DELP-Block ¹ _n to DELP-Block ⁶ _n . The six blocks will be described in detail as follows.

%% ESSTYPE specifies the type of ESS.

%% RAWNAME specifies the path name of the output message of the ESS.

%% DATABASE specifies the database server name, database name, and table name. This block allows you to specify the physical location of the database repository independently of the network management data builder.

%% DEFINE is optional to define a macro to use in the Format block.

%% FORMAT defines the syntax of the output message of the ESS and the data field to be extracted using the expression shown in FIG. In addition, this block specifies various commands such as inserting into a table of the database, and defines that the block can be blocked by %% LOOP and %% ENDLOOP when the output message of the ESS is repeatedly repeated.

Finally, %% EDSCRIPTION defines the formula to calculate the network performance parameter to be constructed using the extracted data, and the tables and columns of the database where the calculated network management data will be stored.

For reference,% ENDFORMAT indicates that the block of %% FORMAT is finished, and% ENDDESCIPTION specifies that the %% DESCIPTION is finished.

As a result, the data extraction language table presents instructions for the interpreter module 26 to extract and calculate the network performance parameters to be extracted from the output message of the ESS and the syntax format to which the output message of the ESS is to be converted.

In the control information file, as shown in FIG. 5, path names of a plurality of syntax information files are registered, and abbreviated names of exchange systems corresponding to path names of the syntax information files are registered, respectively. The path name of the syntax information file respectively indicates the data extraction language tables, and the exchange abbreviation name designates an exchange to analyze a message by applying the data extraction language tables.

Furthermore, the adaptive network management system further includes an interpreter module 26 for processing output messages of the ESS stored in the temporary storage module 22. The interpreter module 26 separates abbreviations of the exchange system included in the output messages of the plurality of ESSs from the n buffers B1 to Bn of the temporary storage module 22, and abbreviations of the separated exchange system. The syntax information file path name is searched from the control information file stored in the memory 24 using the data, and the data extraction language table corresponding to the searched syntax information file path name among the plurality of data extraction information stored in the memory 24 is searched. Read it.

And the interpreter module 26 stores L data management field values (i.e., raw parameters) for five blocks (DELP-Block ¹ _n to DELP-Block ⁵ _n ) indicated in the data extraction language table. Extract 1 or K times. In addition, the interpreter module 26 calculates network performance parameters defined by the network management system from the source parameters according to the contents of the source parameters in the sixth block DELP-Block ⁶ _n of the data extraction language table. The interpreter module 26 stores the raw parameters and network performance parameters in the first and second data tables DT1, DT2 according to the contents described in the sixth block of the data extraction language table.

To this end, the parser module 26 uses first to nth parser TS1 to TSn extracting the raw parameters and the network performance parameters from the ECC message, and the parser using the control information file. An analyzer management unit TM for selectively driving the TS1 to TSn is provided.

The analyzer manager TM stores the ECC messages from the first to nth buffers B1 to Bn constituting the temporary storage module 22 in the memory 24. The interpreter manager TM detects the abbreviation name of the exchange system from the ECC message, and uses the abbreviated name of the detected exchange system to detect the abbreviation name of the ECC message from the control information file stored in the memory 24. Retrieve the path name of the data extraction language table. In addition, the interpreter manager TM drives one syntax interpreter corresponding to a path name of the data extraction language table.

The first to nth parsers TS1 to TSn are selectively driven by the analyzer manager TM, respectively. The first through nth parsers TS1 through TSn extract raw parameters and network performance parameters from an ECC message by using a data extraction language table assigned to the user among the data extraction language tables stored in the memory 24. do. In addition, the first through n-th parsers TS1 through TSn respectively store the raw parameters and the network performance parameters in the second and first data tables DT1 and DT2 included in the database module 28. Save each one.

If the first to nth parsers TS1 to TSn do not have enough working memory to store the ECC message and the data extraction language table corresponding to the first to nth parsers TS1 to TSn, the interpreter module 26 And a working memory for temporarily storing the control information file, the data extraction language table and the ECC messages.

The working memory is accessiblely accessible by the analyzer managing unit TM and the first through nth parser interpreters TS1 through TSn. The working memory also has a function of temporarily storing the raw parameters and the network performance parameters calculated by the first to nth parsers TS to TSn.

The first and second data tables DT1 and DT2 form one database table module 28, the first data table DT1 stores network performance parameters, and the second data table ( DT2) stores the raw parameters. The data tables may describe different database servers, different database names when describing the database server name.

FIG. 6 is a flow chart for explaining the operation of the analyzer managing unit TM shown in FIG. The flowchart of FIG. 6 will be described in conjunction with FIG.

In the thirtieth step, the analyzer manager TM first reads out the control information file as shown in FIG. 5 from the memory 24. The analyzer managing unit TM sequentially inputs the ECC messages from the first to nth buffers B1 to Bn of the temporary storage 22 and stores the ECC messages in the memory 24. After performing step 30, the analyzer manager TM searches whether there is an ECC message stored in the memory 24 (step 32).

If there is an ECC message in step 32, the interpreter manager TM searches for the control information file using the abbreviation name of the exchange system included in the searched ECC message and corresponds to the syntax information file corresponding to the searched ECC message. Search for the path name (step 34). The parser manager TM drives one of the first to nth parsers TS to TSn corresponding to a logical value of the syntax information file path name (step 36).

After performing the step 36, the analyzer manager TM performs the step 32 again to search whether there is an ECC message to be processed in the memory 24. At this time, if there is an ECC message to be processed, the analyzer manager TM performs steps 34 and 36. On the contrary, if there is no ECC message to be processed, the analyzer manager TM ends the operation.

FIG. 7 is a flow chart for explaining the operation of the parsers shown in FIG. 7 will be described in conjunction with FIG.

The syntax interpreter TS reads the data extraction language table assigned to itself from the data extraction language table stored in the memory 24 when an instruction to process an ECC message is received from the interpreter manager TM. (Step 40). The syntax interpreter TS allocates storage areas on the first and second data tables DT1 and DT2 in which the raw parameters and the network performance parameters are to be stored (step 42).

After performing step 42, the parser TS searches whether there is an ECC message to be analyzed in the memory 24 (step 44). If there is an ECC message to be analyzed in step 44, the parser TS reads the first block of the retrieved ECC message from the memory 24 (step 46).

The syntax interpreter TS performs a pattern matching with the syntax of the data extraction language table on the first block of the read ECC message to check whether the ECC message is the correct syntax (step 48). If the first block of the ECC message does not match the syntax of the data extraction language table in step 48, the syntax interpreter TS ignores the ECC message stored in the memory 24 (step 50). Step 44 is again performed to search for the presence of another ECC message to be analyzed.

Alternatively, when the first block of the ECC message matches the syntax of the data extraction language table in step 48, the syntax interpreter TS reads the ECC message stored in the memory 24 to extract the data extraction language. Raw parameters are extracted from the read ECC message according to the table (step 52). After performing step 52, the syntax interpreter TS calculates network performance parameters from the source parameters as defined in the data extraction language table (step 54). The syntax interpreter TS stores the raw parameters and the network performance parameters in storage areas on the first and second data tables DT1 and DT2, respectively (step 56).

In addition, the parser TS performs step 44 again to check whether there are other ECC messages to analyze. If there is no ECC message to analyze in step 44, the parser TS switches to standby mode and waits until the ECC message to be analyzed is stored in the memory 24 (step 58). .

Only necessary data are extracted from the message input through the above processes.

For reference, how the above processes operate in the actual network management system will be outlined and summarized.

An exchanger having said memory means and an interpreter module embedded in the data receiving side of the network management system, initially transmitting a request message to transmit a message from exchanges connected with the network management system once and then inputting Receive all messages. The online communication module separates only the messages needed for network management among all received messages and stores them in the temporary storage.

The interpreter module selects a syntax interpreter to be used according to the data type to be extracted based on the message type and the abbreviation list information of the exchange included in the control information file, and the parser refers to the data extraction language table stored in the memory means. Analyzes messages stored in temporary storage.

In this state, when the output format of the pre-connected exchange message is changed or the performance is upgraded, the output message is changed accordingly. Therefore, the information according to the change of the output message is modified in the data extraction language table. In addition, when a new exchange system is additionally accommodated, the corresponding exchange information and the data extraction language table information are added to the control information file.

By doing so, even if the exchange is connected, the network management system can immediately accommodate the change of the network management environment by modifying the control information file or data extraction language table without any additional S / W change or additional development process.

Such a network management technology can be applied to all technologies for managing data such as a signal network and a subscriber network as well as the communication network illustrated in the present invention.

Therefore, it is possible to analyze the output messages at all exchanges only by changing the data extraction language table, thereby reducing the system modification time and economic benefits.

As described in detail above, the adaptive network management system of the present invention processes the output messages of the ESS by generalized syntax information instructing to extract different raw parameters and network performance parameters according to the type of message of the ESS. Can be. For this reason, the adaptive network management system of the present invention changes information on a message without additional S / W supplement or additional function development in order to analyze a message that has changed during operation of the system or a message of an exchange type to be additionally accommodated. That is, the data extraction language table only) provides an advantage that can be readily accepted.

In addition, since the addition or deletion of network management data to be constructed due to the expansion of network management function is simply made by additional calculation calculation for the corresponding item in the data extraction language table or deletion of the expression for the corresponding item, the increase or decrease of the construction item There is this free advantage.

In addition, the data storage function for data calculated to make the data storage function independent of the database schema is not limited to a specific table, but the database server system, database, table and column information can be referred to by referring to the message information file during system operation. I separated the software and the database schema by doing so.

Finally, the adaptive network management system of the present invention has the advantage of simplifying the interior of the network management system because of having a single interpreter module instead of a plurality of conventional processors.

In addition, preferred embodiments of the present invention are disclosed for the purpose of illustration, those skilled in the art will be able to various modifications, changes, additions, etc. within the spirit and scope of the present invention, such modifications and modifications belong to the following claims You will have to look.
