The present invention relates to a network management control device, and in particular, network management control to transmit only the data requested by the operator by limiting the number of messages received by filtering by the needs of the operator when interworking between the network management entity and the management agent. Relates to a device.

Conventionally, it exists in the form of accepting management of only one exchange through a management terminal for the operation of the exchange. As the number of entities to be managed and the network becomes complicated, the International Telecommunication Union (ITU-T) The International Telecommunication Union has adopted a Telecommunications Management Network (TMN: Telecommunications Management Network).

Asynchronous transfer mode (ATM), which is currently under development, is referred to as an asynchronous transfer mode. The switching system node also adopts an integrated management model through a telecommunications management network, with reference to the accompanying drawings. The explanation is as follows.

1 is a block diagram showing a configuration of a conventional network management and control device, which is composed of a workstation (Workstation 10) and the switch 20, as shown therein, the workstation 10 and the operator terminal and An HMI client (Human-Man Interface Client) 11 for requesting a service for communication of the service, an HMI server (Human-Man Interface Server) 12 for the HMI client 11 to respond to the request, and A connector unit 13 for branching a message received from the HMI server 12, a configuration manager 14 for managing a configuration functional area of the message from the connector unit 13, and the connector Connection management unit 15 for managing the connection functional area of the message from the unit 13, and fault management unit 16 for managing the fault functional area of the message from the connector unit 13 Exchanger 20 stores data HANDF (HMI Adaptater & Deliver Function) 21 for transferring to HMI server 12 or transferring data from HMI server 12 to exchanger 20, and a database interface unit for collecting and transmitting initialization data (DBIF). : DataBase InterFace (22), and Operation and Maintenance Processor (OMP: Operation and Maintenance Processor) (OMP) 23 to handle the failure of the operator or to process the data. same.

First, the HMI client 11 of the workstation 10 is generated for communication with an operator terminal and requests a service from the HMI server 12, and accordingly the HMI server 12 requests the HMI client 11. Answer the request of

For reference, the HMI client 11 and the HMI server 12 exchange data information through an IPC (hereinafter referred to as IPC) socket communication.

Next, the connector unit 13 branches the message received from the HMI server 12, where the configuration management unit 14 manages the configuration functional area of the message from the connector unit 13, and the connection management unit ( 15 manages the connection functional area of the message from the connector unit 13, and the failure management unit 16 manages the failure functional area of the message from the connector unit 13;

Here, the connector unit 13 also exchanges information with the HMI server 12 via IPC socket communication in the same manner as the HMI client 11, and the HANDF unit 21 as a process inside the exchanger is transferred from the exchanger 20. The data is transferred to the HMI server 12 or the data from the HMI server 12 is transferred to the exchanger 20.

In addition, the database interface unit 22 of the exchanger 20 collects and transmits initialization data. The data obtained through the database in the exchanger 20 is transmitted during initial operation of the telecommunications management network to ensure consistency of data. In doing so, the operation maintenance processing unit 23 performs a failure occurrence operation or data processing.

The following three cases exist in the communication between the switch 20 and the telecommunications management network operator terminal. First, the telecommunications management is a message in which a system output message generated by the operator 20 is graphicized. Shown to the network operator.

In the first case, the operation maintenance processing unit 23 recognizes when a hardware alarm occurs, and transmits the recognized result to the HANDF unit 21, whereby the HANDF unit 21 re-enters it in the workstation. Transfer to HMI server 12.

Accordingly, the HMI server 12 transmits the message to the connector unit 13 and the HMI client 11, so that the HMI client 11 transmits a message to the local operator terminal, and the local operator recognizes this data. The same message sent to 13 informs the telecommunications management network operator via the telecommunications management network.

The second is when the telecommunications management network operator is shown to enter a command to perform the intended operation on the exchange.

In the second case, when a command is issued from the telecommunications management network operator terminal, the data is branched to the configuration management unit 14, the connection management unit 15, and the failure management unit 16 depending on the function, and this data is transferred to the HMI server 12. Is sent.

As such, the data transmitted to the HMI server 12 is changed into a message form that can be processed by the HMI while passing through the connector unit 13 in the form of the first telecommunications management network message, which is converted into a message form of the switch 20. Processing is performed through the operation maintenance processing unit 23.

Third, the exchange performs the command of the telecommunications management network operator to show the performance result to the telecommunications management network operator.

The third case is a process of processing a response to the command of the second case, and the message flow is the same as the case where the first one is sent.

That is, communication is performed between the exchanger 20 and the operator terminal in the form of a message according to three situations. The message type in this case is from the original data and the agent to the manager in the exchanger 20. The telecommunications management network message forms exist and can be regarded as a process of performing message conversion between them.                         

As such, the connector unit 13, the configuration manager 14, the connection manager 15, and the failure manager 16 used for the telecommunications management network connection in the asynchronous transmission mode switch are a type of client using the HMI server 12. As a form applied to the workstation (10).

2 is a diagram illustrating a conventional message conversion process, and shows a process of changing to a telecommunications management network message using a response message sent from an exchange as shown in FIG.

Here, the message structure used in HMI is shown at the top, and the message type sent based on this structure corresponds to the HMI message type of the second process.

In addition, the following briefly shows only the necessary message part in the HMI message form, and translates it into a telecommunications management network message form.

However, in the prior art operating as described above, the HMI server communicates through the HMI server and receives the exchanger output message in the form of HMI message, and each HMI message is transferred to the connector portion, thereby providing more than the data required by the operator. As all messages are sent, communication between the exchange and the workstations will process all of the messages sent by each operating block in the exchange, causing a problem that will increase the load on the system.                         

In addition, there is a problem in that the software development period increases as a detailed change of the relevant software for message translation occurs every time a message is added, deleted, and changed as the message is translated.

This means that if the field is increased or decreased as the instruction is processed as a byte stream, the development time is increased due to change overhead, and the same data file as the exchange is translated to the workstation during the initialization process as the operation block in the exchange translates the data to the target. There is a problem that the original data, which is each byte stream, must be interpreted based on the loaded information.

Accordingly, the present invention has been made in view of the above-mentioned problems, and in order to transmit only the data requested by the operator by limiting the number of messages received by filtering by the needs of the operator when interworking between the network management entity and the management agent. It is an object to provide a network management control device.

The present invention for achieving the above object, the communication with the exchange to handle the telecommunications management network request from the management agent, filtering from the management agent to define the type of messages needed by the management agent A service control coordination unit for receiving and transmitting a condition, and requesting a telecommunications management network request from the service control coordinating unit to each component of the exchange, and requesting failure and status information of a message received from the following operation maintenance processing unit; A service switching interface unit for filtering based on the filtering condition transmitted from the service unit and transmitting the same to the management agent; and an operation maintenance processing unit for analyzing a message received from the service switching interface unit or transmitting a message to the service switching interface unit. It is characterized by the configuration.

Hereinafter, operations and effects on the network management control apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

3 is a block diagram showing the configuration of the network management and control apparatus of the present invention. As shown in FIG. 3, a communication with an exchange is performed to process a telecommunications management network request from a management agent, and a filtering condition is input from the management agent. The service control coordination unit 31 which receives and transmits, and requests the telecommunications management network request from the service control coordination unit 31 to each component of the exchange, the failure and status of the message received from the following operation maintenance processing unit 33 Based on the filtering condition transmitted from the service control adjustment unit 31, the service switching interface unit 32 for transmitting the filtered information to the management agent and the message received from the service switching interface unit 32, or Operation maintenance processing unit 3 for transmitting a message to the service switching interface unit 32 3), the operation of the present invention configured as described above is as follows.

First, the service control coordination unit 31 communicates with an exchange in order to process a telecommunications management network request from a management agent, and receives a filtering condition for defining a type of a message required by the management agent from the management agent. This is transmitted to the service switching interface unit 32.

Then, the service switching interface unit 32 requests the telecommunications management network request from the service control coordination unit 31 to each component of the exchange, and the failure and status information of the message received from the following operation maintenance processing unit 33. Is filtered based on the filtering condition transmitted from the service control adjustment unit 31 and transmitted to the management agent via the service control adjustment unit 31.

The operation maintenance processing unit 33 analyzes the message received from the service switching interface unit 32 or transmits the message information of the exchange to the service switching interface unit 32.

FIG. 4 is a block diagram showing the configuration of the service control coordination unit in FIG. 3, wherein the service control coordination unit 31 implemented in the workstation as shown in FIG. 3 is the service switching interface 32 of the management agent 30 and the exchange. As an interface between the terminals, a telecommunications management network message is transmitted to the telecommunications management agent 30, and the exchange is required to transmit only the necessary information to the manager.

Then, the service switching interface unit 32 of the exchange performs filtering on the required information from the service control coordination unit 31, and directly receives the message to seek the simplification of the process.

Here, the service switching interface unit 32 implemented on the switchboard receives the filtering condition from the service control coordinator 31 implemented in the workstation and manages the type of message transmitted to the manager.

These types of message management include configuration management functions for managing configuration information management, station data management, route management, route scenario management, signal point management, and time management functions, and management of permanent virtual circuit (PVC) connections. There is a connection management function, a fault management function for managing fault history management and alarm level, and a performance management function for managing performance.                     

That is, the service switching interface 32 is software in the exchange, and the communication with the service control coordination unit 31 is integrated into ten or more messages to simplify message transmission. It consists of several, one for each of the fault, connection, and performance messages.

In order to implement the present invention, there is provided a library that can be used by the person in charge of each exchange component, which library analyzes messages from the service switching interface 32 or switches services in the exchange operation maintenance processing unit 33. It performs a function of transmitting a message to the interface unit 32 and is provided in the form of an application program interface (API).

That is, the exchange calls the corresponding application program interface and obtains the desired data by extracting the corresponding field from the message content. In other words, the service control coordination unit 31 implemented on the workstation exchanges with the telecommunications management agent 30. It operates as an interface of a period, exchanges messages with the service switching interface unit 32 through Ethernet communication, exchanges messages with the management agent 31 through a socket, and a message queue. It has an interface to support it.

Accordingly, the service control coordination unit 31 receives the telecommunications management network request message from the management agent 30 and transmits it to the service switching interface unit 32 in the exchanger through the IPC passage, and vice versa from the service switching interface unit 32. Receives and transmits a telecommunications management network message to the management agent (30).

Then, the telecommunications management agent 30 transmits an event detection message for filtering the exchanger message that the operator does not need to the service control coordinator 31, and the service control coordinator 31 transmits the information to the service switching interface unit. Requested by (32) actually performs filtering when unnecessary messages are detected.

In this way, since message conversion is not performed in the intermediate process between the management agent 30 and the exchange, management such as modification and addition of a program is facilitated.

As described in detail above, the present invention has the effect of limiting the number of messages received by filtering by the needs of the operator when interworking between the network management entity and the management agent to transmit only the data requested by the operator.

It also reduces the load on the system by ensuring that administrators do not receive anything other than the common data required by each agent, reducing the load on the system, improving efficiency in future system development, and improving the performance of multiple network entities in the switching system. There is.

In addition, changes can be made to simplify the process of message conversion, greatly reducing implementation time, and reducing the trouble of finding parameter positions in the interface program every time when changing, adding, or deleting commands, and assuring the efficiency of management. By simplifying the number to around 10, the interface between the exchange operator and the telecommunications network operator can be reduced to clarify the message conversion process.
