Description

Initial Data Generation Method in Communication Management Network Agent System for Exchange

The present invention relates to an initial data generation method for generating initial data in a communication management network agent system for an asynchronous delivery mode switch.

Telecommunication Management Network (TMN) functions based on the Common Management Information Protocol (CMIP) standardized by the International Organization for Standardization (ITU-T) and the Asynchronous Forum (ATM Forum) are being implemented worldwide. In Korea, it is implemented in MSS (Metropolitan Switching System) exchange. The initial data generation of the agent in the MSS is a method of polling related applications in the agent to obtain data or transmitting the data to the agent when the hardware is initialized.

In this conventional method, since the initial data generation of the agent depends on the related hardware and the functions of other applications, the time required to generate data is long, and the application and the related hardware when an extension or additional situation occurs. There was a problem that needs to be corrected firmware.

Although there is a conventional method of generating the initial data manually in the agent system instead of using the automatic method, this method may cause the asynchronous transfer mode (ATM) switch and the telecommunication agent (TMN Agent) to always have incorrect data. The possibility exists that normal and accurate network management is impossible.

Therefore, in order to collect accurate data even when the components and state of the asynchronous delivery mode exchange change at any point, it is necessary to automatically collect data necessary for performing the agent function from the asynchronous delivery mode exchange.

In order to solve the above problems, the present invention provides a normal and accurate communication network management by generating initial data by automatically collecting initial data necessary for performing a function by an agent as a management agent in a communication management network system. Its purpose is to provide an initial data generation method to be achieved.

In order to achieve the above object, the present invention, in the initial data generation method applied to the communication management network agent system for a switch, for storing data for the relation required in the agent system for the initial data generation of the communication management network agent A first step of sequentially requesting data for relation to the operational maintenance processor of the exchange after generating the file; A second step of collecting, by a database management system (DBMS), data about a relation from a database management system (DBMS) and transmitting the data on a relation from the agent system to the agent system; And a third step in which the agent system, which has received data about the relation from the operation maintenance processor, stores the data about the relation in a parasitic file.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention;

1 is a connection diagram of an asynchronous delivery mode (ATM) exchange and an agent system to which the present invention is applied.

The asynchronous delivery mode switch is composed of two subsystems, an agent system 110 and an ATM Central Switching Subsystem (ACS) 101 and an ATM Local Switching Subsystem (ALS) 102.

The ACS 101 performs a function of operating, maintaining, and managing a system, and maintaining various traffic information, statistics, and billing information, and includes an operation and maintenance processor (OMP) 103. have.

The ALS 102 is a processor that performs access processing of a general subscriber. The ALS 102 performs access control according to a subscriber service request together with a subscriber matching circuit, and performs a traffic control function such as access admission control and congestion control. . The ALS 102 provides data for asynchronous delivery mode exchange components managed by a communication management network agent. The ALS 102 is installed in multiple numbers depending on the subscriber and includes a Call Connection Control Processor (CCCP) 104.

The Central Switch Network Module (CSNM) 105 is responsible for the switches for each Access Switch Network Module (ASNM) 106, and the ASNM 106 is responsible for the subscriber switches in the ALS 102. Operational Maintenance Processor (OMP) 103 is connected to one port of CSNM 105 and CCCP 104 to one port of ASNM 106 via an Inter Module Interface (IMI) link, respectively, to send and receive messages. The communication between the CCCP 104 is made through the three-stage structure of ASNM-CSNM-ASNM, and the communication between the operation maintenance processor (OMP) 103 and the CCCP 104 is made through the two-stage structure of the CSNM-ASNM. .

In the Operational Maintenance Processor (OMP) 103, as part of the present invention, there is a Data Base Interface Function (DBIF) 107, which is a block for collecting initial data required for an agent system from an asynchronous delivery mode switch. Obtain from Local Data Base (LDB) 109 by calling DBMS (Data Base Management System) 108. The DBIF 107 can also obtain data residing in a processor other than the operational maintenance processor (OMP) 103 by using the distributed DBMS 108. The DBMS 108 of the Asynchronous Transfer Mode Switch has a distributed structure for managing data distributed among multiple processors, and resides in main memory for real time processing.

In the agent system 110, there is an agent 111 that performs the function of requesting the initial data generation of the present invention and creating a required file, and performs a communication with the operation maintenance processor (OMP) 103. Spar Real-time Operating System (D) 112 is included. Initial data for the agent 110 collected by the operational maintenance processor 103 is present in various files on the disk 113 present in the agent system 110.

Figure 2 is a block diagram showing the flow of the agent system, asynchronous transfer mode (ATM) switch and the message to which the present invention is applied.

Agent main process 202 present in agent system 201 calls a Network Element Interface Function (NEIF) 203 block to generate the necessary initial data. The NEIF 203 maintains in a file a list of relations containing data required for the telecommunications agent system 201, and operates from the first maintenance of the list in the ACS 204 of the asynchronous delivery mode switch. A data base interface function (DBIF) block 206 of 205 requests initial data transmission of the communication management network agent system. DBIF 206 obtains the data of the requested relation by calling DBMS 207 and sends it to NEIF 203 present in agent system 201. The NEIF 203 opens a file for storing data of the relation and stores the received data on the disk 208.

This process is performed for all relations in the list maintained by the NEIF 203 to complete initial data generation of the communication management network agent. When the initial data generation is completed, the agent main process 202 calls the configuration management process 209 to perform the initialization of the agent system 201.

3 is a flowchart illustrating an initial data generation operation procedure in an agent system according to the present invention.

When the operation of the agent main process is started in the agent system (301), the NEIF is executed to generate initial data to be used in the communication management network system (302). The NEIF opens a file containing the list of relations used for generating the predefined initial data (303) and retrieves the name of the relation and the processor name in which the relation exists (304). If the end of the file is checked (305), a file for storing data for the relation is created on the disk (306). A message including the relation name and the processor name is formed to transmit a message to the DBIF block existing in the operation maintenance processor of the asynchronous delivery mode exchange to request data for the relation (307). A time out is set for the time to wait to receive a message from the operational maintenance processor (308) and transitions to the waiting state (309). On the other hand, if the result of checking whether the end of the file is the end of the file closes the file containing the list of relations (316). If an error exists (317), an error message is output (318) and an abnormal completion is reported to the agent main process (319). If no error is reported to the agent main process normal completion (320) and terminates.

The network element matching function (NEIF) releases the set time out when data is transmitted from the DBIF block of the operation maintenance processor (310) and checks whether it is the end of the data (312), or generates it in advance if it is not the end. The data file is stored in a relation unit (313). A time out is set to receive the next data (314), and the state transitions to the waiting state (309). At the end of the data for the relation, close the created data file (315), and retrieve the relation name and processor name from the file containing the list of relations to request DBIF data for the next relation (304). Repeat from now on. If a time out occurs due to a communication failure or a function failure and no response to the data transfer request from the DBIF of the operation maintenance processor occurs (311), the file including the list of relations is closed (316). If an error exists (317), an error message is output (318) and an abnormal completion is reported to the agent main process (319). If no error is reported to the agent main process normal completion (320) and terminates.

4 is a flowchart illustrating an initial data collection operation procedure of a database matching function (DBIF) present in an operation maintenance processor (OMP) of an asynchronous delivery mode switch according to the present invention.

The DBIF starts running when the operational maintenance processor starts operation and remains in a waiting state (401), upon receiving an initial data collection request from the NEIF of the agent system (402), the DBMS to collect data for the requested relation. Call (403) and check if an error has occurred from the DBMS (404).

As a result of the check, if there is no error, it checks whether it is the end of the data for the requested relation (405). If it is not the end of the data, it constructs the message as a message (406), compresses it and sends it to NEIF (407). Repeat the process of calling the DBMS (403), and if it is the end of the data, generates a message indicating that the end of the data for the requested relation (408) to send to the NEIF and transition to the standby state (401) (409) Wait to receive a request for the next relation from DBIF.

If an error occurs when the DBMS is called, an error message is generated (410), an error message is transmitted to the NEIF (411), and the state transitions to the waiting state (401) (409) to receive a request for the next relation from the DBIF. Wait

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.

The present invention as described above can obtain the following effects.

First, since the initial data is dynamically obtained from the asynchronous mode switch, the same data as the asynchronous mode switch can be maintained.

Second, by maintaining the same data as the asynchronous delivery mode switch, it is possible to increase the stability and accuracy of network management.

Third, since the initial data is collected from the asynchronous delivery mode exchange by its own function, it is easy to collect additional data.

Fourth, since data is easily collected by its own functions, it is possible to expand and add functions of communication management network agents.
