Abstract

PURPOSE: An apparatus for generating and removing a block of a TMN management agent system is provided to efficiently manage a system by automatically generating and removing a block at which an event is generated, processes of the corresponding block, and blocks influenced by the corresponding block and processes in the blocks. CONSTITUTION: A management agent intrinsic block(122) receives and analyzes an CMIP(Common Management Information Protocol) request message from a TMN(Telecommunication Management Network) manager system(110), and changes and outputs the CMIP request message into inner processing or inner request message. When receiving an inner notice message, the management agent intrinsic block(122) converts the inner notice message into an CMIP notice message to transmit the CMIP notice message to the TMN manager system(110). A CASS(Connector for TMN Agent and ATM Switching System) block(123) converts the inner request message into an MMC(Man Machine Communication) request message defined in an ATM switching system(130) for transmitting the MMC request message to the ATM switching system(130). When receiving an ATM MMC notice message, the CASS block(123) converts the ATM MMC notice message into an inner notice message to transmit the inner notice message to the management agent intrinsic block(122). When receiving an inner request message for initializing the TMN manager system(110), an NEIF(Network Element InterFace) block(124) transmits a file transmission request message for configuration information and state information to the ATM switching system(130). When receiving an initialization file message, the NEIF block(124) transmits a message related to initialization to the management agent intrinsic block(122). A process manager block(121) promptly restores an organic problem between blocks and between processes.

Description

Block generation / destruction device and method of T & M management agent system

The present invention relates to an apparatus and method for generating / destroying a block of a TMN management agent system, and more particularly, to an apparatus and a method for minimizing information loss by quickly recovering when a plurality of processes existing in a system are down. .

In general, the TMN management agent system (Telecommunication Management Network Agent system) is configured based on the concept of the TMN, thereby the block and TMN and non-TMN (non-TMN) that acts as a unique management agent for network components It consists of the Q_ADAPTOR block and the blocks related to initialization. When such blocks are processed by creating one output file for each block, one screen is required for each block. In practice, however, the operator needs only one command from the administrator, whether the command is properly delivered to the manager or the command from the manager. For this purpose, the output files of each block are made by using a script to drive the TMN management agent system.

However, such a conventional method is affected by a manual method when the internal process of each block affects the process of other external blocks due to a down or unexpected situation in the running state. The TMN management agent system has been managed through an inefficient method of stopping and resuming blocks and affected blocks.

Therefore, when an operator needs to check the event that occurs due to the down or unforeseen situation of the process of the corresponding block occurring in the method using a conventional script or the process of the block or the process inside the block during the operation of the TMN management agent system. When down, the processes had to be destroyed and created according to the situation in which the downed block or process and the affected block or process were manually issued by the operator. Therefore, the conventional method of manually destroying and generating processes as described above has caused a loss of information due to recovery time, and in a severe case, when the recovery time is long, there is a problem that the entire initialization of the TMN management agent system needs to be executed again.

Accordingly, an object of the present invention is to provide an apparatus and method for automatically handling a problem that is predicted when an internal process of a TMN management agent system occurs when operating a TMN management agent system using a processor manager.

It is another object of the present invention to provide an apparatus and method for improving efficiency of system operation while minimizing loss of information through rapid recovery during process down in a TMN management agent system.

TN management agent system according to an embodiment of the present invention for achieving the above object, receives the CMP request message from the TN manager system and outputs after analysis and change to the internal processing or internal request message, after processing or internal notification Upon receipt of the message, it converts the CMP notification message into a management agent unique block for transmitting to the TMS manager system, and when receiving the internal request message, converts it into an MC request message defined by the ATM switch and transmits the message to the ATM switch. A CS block converting an internal notification message upon transmission of an MMC notification message to a unique block of the management agent, and a file for configuration information and status information upon receiving an internal request message for initializing the TMS management agent system. Send a request message to the a The NIF block which transmits to the M exchange, and transmits the initialization-related message to the management agent unique block upon receiving the initialization file message, and the organic problem between the internal block and the block of the TMB environment or between the process and the process. It is characterized by consisting of a process manager block to recover in a short time.

The TMN management agent system according to an embodiment of the present invention automatically processes the block or process of the block and the affected block or processes in which the incident occurred. To this end, in consideration of the organic association of each block and the association of the corresponding processes, the process manager reports a status of a down or unexpected situation occurring in each block or a process within the block. In addition, according to the status reported above, the process manager automatically destroys and creates processes in the block or blocks and the affected blocks or blocks in the block, thereby reducing unnecessary actions of the operator and minimizing recovery time, thereby losing information. By minimizing this, the overall system operation efficiency is improved.

In FIG. 1, (1) is a CMIP request / notification message on a TMN manager system 110 and a management agent unique block 122, and (2) is an internal request / notification message between a TMN management agent unique block 112 and a CASS block 123 which is a Q_ADAPTOR block. (3) is an initialization-related internal request / notification message between TMN management agent-specific block 112 and NEIF block 124, which is a block for generating an initialization file, and (4) is defined between the CASS block 123 and ATM switch 130. MMC request / notification message, (5) is a file transfer message between the NEIF block 124 and the OMP block 131, which is an internal block of the ATM switch 130, (6) the internal of the TMN management agent system 120 by a third process This is a command message where blocks are created and destroyed.

Referring to FIG. 1, a management agent-specific block 122 of the TMN management agent system 120 exists inside the TMN environment, and receives a notification message from a switch and a routine for receiving and processing a CMIP request message from the TMN management system 110. It is divided into routines to receive and process. When the CMIP message is received by the TMN manager system 110, the received message is analyzed and processed internally after being analyzed by the management agent's own block 122, and then converted into a CMIP message and transmitted to the TMN manager system 110. In addition, when information from the exchange 130 is needed, an internal request message defined by the CASS block 123 is created and transmitted, and a response message for the request message is received, and a CMIP response message for the TMN manager system 110 request is received. Make and send.

The CASS block 123 is a block used to convert a message of the TMN environment into a message of a non_TMN environment or a message of a non_TMN environment message to a TMN_environment message. It converts the message transmitted in the form of MMC command used in 130, or in the form of MMC command used in the ATM switch 130 to the message of the unique block 122 of the management agent. In the TMN concept, this is called Q_ADAPTOR.

The NEIF block 124 is used to initialize the configuration information and state information necessary for the initialization of the TMN management agent system 120 into a block set to obtain from the database of the exchange 130, and is driven even during operation by the request of the management agent's unique block 122. This is possible.

The process manager block 121 may solve organic problems between the block and the block or between the process and the process that occur during process down due to an abnormal situation of the blocks constituting the inside of the TMN management agent system 120 and the processes present in the block. Minimize information loss by automatically recovering at the earliest possible time.

FIG. 2 is a diagram illustrating a process of generating an internal block of the TMN management agent system 120 and a corresponding process using the process manager block 121 of the TMN management agent system 120. The process of generating the entire process proceeds as follows.

When the process manager block 121 is driven, the NEIF process of the initialization-related NEIF block 124 is created in step 201. After confirming the creation of the NEIF process proceeds to the next process. After the NEIF process is generated, the process management block 121 generates a management agent process that is a management agent-specific block 122 in step 202. Subsequently, in step 203, the system processes the message of the exchange 130 in the CASS block 123 and classifies it as a related process, and the generated process is a notification message from the exchange 130 generated during the initialization process and the exchange 130 generated during operation. Create a system thread that receives and stores notification messages from.

In step 204, the management agent process issues a start command to the NEIF process, which is an initialization related block 124, and in step 205, the NEIF process manages the TMN through communication with DBIF133 inside the OMP block 131, which is an internal block of the ATM switch 130. After importing the data necessary to drive the agent system 120, the initialization completion message is transmitted to the management agent process.

Then, in step 206, if the response message from the NEIF processor, which is an initialization-related block, is NOK, the management agent process repeats steps 204 and 205 until an OK message is received. Create MIT using data. Thereafter, the management agent process notifies that the initialization of the TMN management agent system 120 is completed in step 207 to generate a process related to failure, charging, configuration, and connection existing in the CASS block 123.

Then, the process manager block 121 performs process 211 in step 208 to generate failure, charging configuration, and connection processes in the CASS block 123 as follows. First, in step 208, a failure process constituting the CASS block 123 is generated and driven. Secondly, in step 209, a charging process for constituting the CASS block 123 is generated and driven, and the generated charging process generates and runs a charging thread necessary for analyzing a notified message from an exchange. Third, in step 210, a process of configuring the CASS block 123 is generated and driven, and the generated configuration process generates and runs a configuration thread necessary to analyze a notified message from an exchange. Fourth, in step 211, a connection process constituting the CASS block 123 is generated and driven, and the generated connection processor generates and runs a connection thread necessary to analyze a notification message from an exchange.

FIG. 3 is a diagram for describing a downtime generation processing operation of the management agent-specific block 122 among the internal blocks of the TMN management agent system 120. An internal processing routine is performed through the following process.

First, in step 301 when the management agent process is down, the operating system notifies the process manager of the process identifier and status value of the management agent process. Then, the process manager analyzes the process identifier and the state value received from the operating system in step 302, and creates and runs a management agent process when the management agent process is down. At this time, if the analyzed state falls into an unknown state, an existing management agent process is destroyed and a new management agent process is created.

Then, in step 303, the generating agent management agent process requests stored data from a database that stores data from the time of initialization to the time when the management agent process is down. In operation 304, the manager agent process receives data stored from the database.

The generated management agent processor that receives data from the database generates an MIT in step 305. This means to create a managed object instance that has been created so far from the received data. Thereafter, the management agent process creates and runs internal threads existing in the unique block 122 of the management agent in step 306.

4 is a diagram illustrating an automatic generation process when an internal process of a Q_ADAPTOR related block is down among the internal blocks of the TMN management agent system 120. The internal structure of the Q_ADAPTOR related block includes a system, an error, a charging, a configuration, a connection, and the like. It consists of five processes and four threads: system, billing, configuration, and connection. When each thread is down, the parent processes are automatically generated, and when each process is down, an auto-generating routine is executed through the following steps.

First, when a process down existing in the Q_ADAPTOR related block is down, the operation system notifies the process manager of the process identifier and status value of the corresponding process. And when the process crashes, it automatically destroys the child threads it created.

Then, the process manager analyzes the process identifier and the state value received from the operating system in step 402 and creates a new manager agent process when the corresponding process is down. However, if the analyzed state falls into an unknown state, the management agent process already existing is destroyed and a new management agent process is created. If the generation processing routine fails, the process is repeated until the process is generated. Then, the process generated as described above generates and runs a child thread necessary to analyze a message notified from the exchange in step 403.

As described above, the method of processing the TMN management agent system according to an embodiment of the present invention automatically processes the corresponding block or the process of the block and the affected block or processes. To this end, by having a third process manager in the TMN management agent system, in consideration of the organic association of each block and the association of the corresponding processes, the process manager is responsible for the down or unexpected situation occurring in each block or process within the block. The status is reported, and the process manager automatically destroys and creates the block or processes within the block and the affected blocks and processes within the block according to the reported status. By automatically destroying and generating blocks and processes as described above, it is possible to reduce unnecessary actions of the operator and to efficiently perform system management as a whole. In addition, immediate action is taken on blocks within the TMN management system and processors down within the block, thus minimizing loss of information, thereby ensuring overall reliability of the TMN management system and improving the performance of the TMN management system. can do.
