Description

{Method of transmitting a message between telecommunication system and agent system of telecommunication network}

The present invention provides a data transmission method for a status report and a response to a control command from a subscriber interworking communication system to a network management agent, wherein the subscriber interworking communication system and the network management agent share data order and type information, By transmitting data, the present invention relates to a data transmission method that can more flexibly respond to message fluctuations and deliver information quickly.

In general, the operation management system of the subscriber interlocking communication system includes an application process (1) for generating state information for system operation management as shown in the schematic structural diagram of FIG. 1, and text for the state information generated from the application process (1). It consists of an operator matching module (2) which generates a message and transmits it to the operator terminal (3), the management agent (4) and the device manager (5).

At this time, in order to minimize the effect on the system when outputting messages, methods such as reducing the number of interprocess IPC communication and data size should be taken in developing the system. Most of the large communication systems in Korea are developed in consideration of this aspect. One way is to use output message description (OMD) data (D), which is data for output message format.

In addition, the system status information should be output to the operator terminal (3), and also passed to the element management system (EMS) (5) to allow the remote operator to monitor the status of the managed system through the device manager. In order to transmit the status information to the device manager 5 and the management agent 4 or to perform a response to the control command, the operator matching module 2 transmits data through a separate application process, or Alternatively, the text message generated by the operator matching module 2 is directly transmitted to interwork with the device manager 5 and the management agent 4.

However, such a data transmission method requires an application process (1) that requires a load that the device manager (5) or the management agent (4) needs to analyze text information or generates a message. It's absurd that you have to send a message.

In addition, the conventional message transmission method as described above has a disadvantage in that it is not easy to modify when a change occurs in the future, and when a large amount of text messages are generated, the amount of transmission is large and the delivery of status and response is not quick.

Accordingly, the present invention is to solve the problems and disadvantages that are pointed out in the method of transmitting message data to the management agent and the device manager in the conventional subscriber interlocking communication system as described above, In order to transmit the response message data more efficiently and quickly, the system operator matching module provides a method of transmitting the dense data to the management agent in the same manner for all messages and receiving and processing the metadata from the management agent. There is an object of the invention.

The above object of the present invention is to create an OMD file, extract fixed data therefrom, and store all information except the variable data value as an OMD data file so that only the variable data value is received from the application process as metadata and corresponding to the data format information. It is achieved by providing a data transmission method between a subscriber interworking communication system and a network management agent to format and output a message.

The meta data refers to data providing information on the message data. The meta data includes the presence or absence of message data per line, a line index, and variable data. The metadata are formed in a compact form as much as the size of each data.

The network management agent analyzes the management commands from the device manager, converts them into internal management commands for the exchange, extracts the management information from the exchange, and delivers it to the administrator. It delivers to the divided management agent and executes the management command for the exchange.

The operation management module in the communication system has an operator matching processing unit.In the case of a domestic development system, detailed information such as the type and content of an output message is managed in an OMD file, which is data for an output message format, and the type of data Specific information is extracted and stored in a data file and used for text message output and analysis.

The operator matching processing unit internally aggregates the output data information by the above information, so that the minimum inter-process communication is performed.

Dense meta data transmission method of the present invention extends the conventional data transmission method as described above, and transfers the metadata already dense by a certain rule to the network management agent based on the information on the data type and type of all messages to be transmitted. And extracting the necessary information by the type and type information of the shared message data from the received metadata.

Detailed description of the above object and technical configuration of the present invention and the effects thereof according to the present invention will be more clearly understood by the following description based on the accompanying drawings.

First, FIG. 2 is a flowchart illustrating a data transmission method between a subscriber interworking communication system and a communication network management agent according to the present invention.

As shown, in order to transmit data between a subscriber interworking communication system and a network management agent according to the present invention, a function developer first defines a name and an output format, and appropriately combines lines defined by OMD in an application program to output a desired message. Create an OMD file so that it can be used (step A101).

Next, the fixed data necessary for outputting to the operator terminal is extracted from the created OMD file using the related developed tool (step A102).

The OMD data file is stored in the OMD data file (step A103) in which all information except for the variable data value itself, such as the extracted fixed data, the format information for outputting the corresponding message, and the index information for searching the information, is stored. Apply to the system.

As the OMD data file generated as described above is applied to the operator matching module, the operator matching module reads the information of the OMD data and recognizes information necessary for outputting all messages.

Accordingly, the operator matching module receives the meta data including the variable data value from the application process (step A104) and transmits the meta data to the management agent (step A105) to transmit the corresponding message.

In the data transmission method of the present invention, the metadata of the message requested for output from each application process is directly transmitted to the management agent through an operator matching processing unit, and is converted into a standardized data structure by the management agent and transmitted to the device manager (EMS).

3 is a flowchart illustrating a message transmission and data extraction process from a subscriber interworking communication system to a network management agent according to the present invention.

As shown, the message transmission process according to the present invention is first defined in the OMD file constituting the message to be delivered by the application process using a library function prepared for outputting a message from the application program to the operator terminal In step B101, the meta data is transmitted to the communication network management agent through the operator matching module.

The network management agent receiving the meta data extracts the type and number of the message from the IPC header received from the operator matching module (step B102).

Next, the network management agent reads the first byte of the metadata received from the operator matching module and checks whether line data exists (step B103), and extracts the line index by reading the next byte if the line data exists (step B104). do.

The network management agent extracts the data format information of the corresponding message line index from the OMD data (step B105), reads the metadata value based on the data format information, and delivers the message to the device manager (EMS). By converting to a standardized data structure (step B106), message transmission and data extraction are performed from the subscriber interworking communication system to the network management agent.

Next, the network management agent transmits the message to the network manager, and then checks whether line data exists again (step B103). For example, if the value is 1, the process is repeated. If the value is 0, the end of the message is completed. This means that the next process is performed.

That is, the management agent automatically maps variable data to a data structure to be transmitted to the device manager (EMS) from the metadata transmitted by the operation management module to the device manager.

As described above, according to the data transmission method between the subscriber interworking communication system and the network management agent of the present invention, the data type and structure of system information such as status, error, and fault information, which are information to be transmitted to the device manager (EMS), are not separately defined. You could develop a management agent based on a data structure file automatically generated by the associated tool from the OMD file.

Accordingly, the present invention provides a method for transmitting data between subscriber communication system and management agent by sharing dense metadata while sharing data order and type information of transmission data, so that a device manager or management agent has a separate load for analyzing text information. It is not required, and it has the advantage that the status and response can be delivered quickly regardless of the volume of the message, and it can cope with the message fluctuation situation more flexibly and if the system uses the same OMD message output method. There is an effect that rapid development of the management agent is possible regardless of the existing system or the new development system.
