Description

How to Perform Configuration Management Commands for Configuration Management in Communication Management Network

The present invention formalizes the data structure of a message transmitted between an agent and an asynchronous transfer mode (ATM) switching system for a Telecommunication Management Network (TMN) configuration management function. The present invention relates to a method of performing a configuration management command capable of performing a configuration management function by a TMN of the same logical type regardless of a switching system.

Currently, Public Switched Telephone Network (PSTN), Integrated Services Digital Network (ISDN), Public Land Mobile Network (PLMN), and Broadband Telecommunication Network (B-ISDN) The emergence of various communication networks, such as ISDN, and the heterogeneity and diversity of the network components that make up these networks, require network operators to provide open, interoperable, and efficient management of networks or equipment to network operators. do.

TMNs with standardized interfaces and information models have attracted considerable attention as network management tools that can meet these needs.

However, TMN has the basic concept of exchanging management information between manager and management agent through standardized interface, but the interface between ATM exchange system and management agent, which is the management entity that is managed by TMN, is solved by developers outside the TMN category. It remains a challenge to be done.

Conventionally, since too many diverse and heterogeneous network elements are interspersed to define TMN and interface between them as standard standard, one formal interface is not devised and it is developed and used arbitrarily according to the developer's intention. There has been a problem of wasting system resources and executing unnecessary procedures by transferring unnecessary information.

In order to solve the problems described above, the present invention is formed by a communication management network (TMN) system that is logically independent of an exchange system that is a management entity by formalizing a data structure of a message transmitted between a management agent and an exchange system. An object of the present invention is to provide a method of performing a configuration management command that performs a configuration management function.

13: Management Agent System 14: Asynchronous Transfer Mode (ATM) Switching System

In order to achieve the above object, the present invention provides a method for performing a configuration management command applied to a communication management network, comprising: a first step of formalizing a structure of configuration management data transmitted through an interface between a management agent and an exchange system; A second step of checking a message type according to a type of configuration management command received from an administrator, storing information on each management command, and transmitting the received information to the switching system; A third step of confirming the type of command in the switching system to perform a configuration command using the message information extracted according to the message type, and then transmitting the result of the execution to the management agent; And a fourth step in which the management agent analyzes the command identifier of the execution result data and calls the corresponding command processing routine, processes the information of the management object and reports the command execution result to the manager.

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

FIG. 1 is an example of hardware to which the present invention is applied and shows a configuration diagram of a communication management network (TMN) system and an ATM switching system 14.

The TMN is a TMN operator 11 who operates a TMN, a manager system 12 that manages management information of an actual communication network, a management agent system 13 that provides management information to the manager system 12, and a management target of an actual TMN. It consists of ATM switching system 14 which becomes.

The TMN operator 11 manages / controls the manager system 12 through a Graphic User Interface (GUI).

The manager system 12 transmits management commands transmitted in a graphic or text form through a graphical user interface (GUI) to the management agent system 13 which is physically or logically divided through a standardized queue (Q) interface, or Management information is received from the management agent system 13. In addition, the network management information is generated by collecting and evaluating the execution result of the management command or the status reports of the ATM switching system 14.

The management agent system 13 manages the same shape and state information as the ATM switching system 14 by using a management information base (MIB), which is a collection of managed objects modeled by an object-oriented model. do.

Then, the management agent system 13 performs a series of operations for manipulating the MIB. Here, a communication interface is required between the management agent system 13 and the ATM switching system 14 to collect or report information for operating the MIB from the ATM switching system 14.

That is, the management information type managed by the manager system 13 for the TMN is a message type based on the Q interface, and the type of information reported or input by the ATM switching system 14 is a man-machine language (MML: Man-Machine). Since a message type based on a language has different information types, a communication interface for mutual compatibility function is needed.

Since the communication management network (TMN) protocol requires that these communication interfaces be arbitrarily defined, developers developing TMNs define and use different interfaces.

Therefore, even though there are various interfaces, all management information necessary for the TMN system to manage the network is provided through such an interface, and thus a formal data structure of messages transmitted through these interfaces is required.

2 is a structural diagram of an embodiment of configuration information data used in the present invention, and illustrates a structure of configuration management data transmitted through an interface between the management agent system 13 and the ATM switching system 14.

The configuration information data is classified into a message header part, a message body 1 part, and a message body 2 parts. This is to maintain an efficient amount of transmitted data according to the type of configuration management message.

That is, a message related to basic configuration management uses only one message body and up to two messages for some messages requiring more information such as exchange system route management. Here, whether to use the two message parts is determined based on the information of the header part.

The header part may include a service access point identifier (SAP_Id) (1), a command type (2), a command sequence identifier (3), a message length (4), Message type (5), execution result (6), and command identifier (7).

The service access point identifier (SAP_Id) 1 is information indicating which system or which processor the data is transmitted from. The service access point identifier (SAP_Id) 1 uses this information to determine where to send a response message of the received message.

The command type (2) is information indicating whether the message corresponds to configuration management, failure management, connection management, charge management, or performance management of the TMN.

In a preferred embodiment of the present invention, information indicating a command for configuration management is always included among the types of commands.

The command sequence identifier 3 is information for ordering messages when a result message for one command is transmitted divided into several configuration data formats, or when one command is divided into several commands.

For example, when a TMN operator issues a command for retrieving link status for a particular subscriber board consisting of four subscriber links, the result of the command is to use four pieces of status information corresponding to four links using a configuration management format. 4 times. At this time, the command sequence (3) shows the serial numbers for the four messages.

The message length 4 represents the total number of bytes of information contained in the message 1 part or the message 2 part, and is used for confirming the actual size of the data transmitted and received.

The message type (5) indicates which of the various management commands or result messages corresponding to the configuration management. That is, information for distinguishing various configuration management functions such as board state change, route setting, and board addition.

The execution result 6 is information indicating whether the TMN command is normally executed or failed in the ATM switching system 14. It also shows the cause of failure in case of failure.

The command identifier 7 is a serial number for each TMN configuration management command transmitted by the management agent system 13 to the ATM switching system 14, and is information that can accurately find a command from the management agent system 13. That is, the management agent system 13 may receive several configuration management commands of the same command type (2) and message type (5) from the manager system 12 and transmit them to the ATM switching system 14.

At this time, the management agent system 13 can know whether each result message received by giving the command identifier (7) for each command is a result message corresponding to any command sent by the manager system 12, and confirmed The result message processing routine appropriate for the command can be called and processed and transmitted to the corresponding manager system 12.

Therefore, by using this command identifier 7, asynchronous command processing between the manager system 12 and the management agent system 14 is possible.

Part 1 of the message includes the rack (8), shelf (9), slot (10), board (11), link (12), subsystem (13), hardware module (14), board name (15), and board number ( 16) consists of information.

Indicates the name of the board, and board number 16 indicates the logical shape information of the ATM switching system 14 as information indicating the number of boards corresponding to a specific hardware module to which one board belongs. In addition, the positional information and the shape information are used to find the management object of the management agent system 13.

The second part of the message is the route number 17, network identifier 18, incoming signal point code 19, insertion digit number 20, insertion digit 21, route name 22, route class 23, virtual path. Identifier 24, virtual channel identifier 25, exit bandwidth 26, and entrance bandwidth 27 information.

The route number 17 represents the route number of the ATM switching system 14, and is used to designate a specific virtual pathgroup management object among management objects.

The network identifier 18 is information for identifying a network to which one route belongs. For example, information indicating whether a particular route in a switching system is used for an international network or for a domestic network.

The destination signal point code 19 represents signaling code information of the destination for signaling.

The management agent system 13 may find the upper management object "nniAccess" to which the virtual pathgroup management object belongs by using the network identifier 18 and the destination signaling point code 19.

The insert digit number 20 represents the digit number of the insert digit.

The insertion digit 21 indicates the area code to which the route belongs. Here, the area code represents a station number.

3 is a flowchart illustrating a method for performing a configuration management command according to the present invention, wherein the management agent system 13 manages the configuration by using a configuration data format between the management agent system 13 and the ATM switching system 14. Represents a procedure for performing a command.

First, when the management agent system 13 receives the configuration management command from the manager system 12 (301), it is analyzed whether the received configuration management command is a command belonging to the configuration management (302).

As a result of the analysis, if the configuration management command, the command type information is included in the data format (303), and if it is not a command related to the configuration management, it is returned to receive another command.

Subsequently, a command identifier is assigned to the command received from the manager system 12, the command identifier is stored in the memory, and the command identifier is stored in the data format (304).

Next, it is determined whether the received command is a root related command (305).

As a result of the determination, if the received command is a root-related command, the route information is included in the message part 2 (see FIG. 2) (306), and message type information indicating which command of the configuration management command belongs to the received command. (308).

As a result of determination, if the received command is not a route related command, the physical location information and the logical shape information are included in the message part 1 (see FIG. 2) (307), and the message type information is stored (308).

Then, after storing the total message length and the message order information if necessary (309), the data carrying the system address information (ie, service access identifier information) of the management agent system 13 is transmitted to the ATM switching system (14). (310).

Next, the ATM switching system 14 analyzes the received data to determine whether the type of the command among the five management functions of the TMN is confirmed (311).

As a result of the analysis, if the type of the command is not confirmed, the data is transmitted to the ATM switching system 14 (310).

As a result of the analysis, when the type of command is confirmed, the received service access identifier is stored in the memory to determine which management agent system 13 to transmit the result after processing, and the command identifier to be used by the management agent system 13 is received. In order to keep the value as it is (312).

Thereafter, it is determined whether the type of the message regarding the command corresponding to the command of the configuration management function is checked (313).

As a result of the check, if the message type is not confirmed, the data is transmitted back to the ATM switching system 14 (310).

As a result of the check, if the message type is confirmed, configuration management information of one message or two messages (see FIG. 2) is extracted (314).

Next, the command is executed using the extracted information (315), and the result is recorded in the data format of FIG. 2, and then the service access identifier stored in advance is checked (316) and transmitted to the corresponding destination (317). .

Thereafter, after receiving the result message from the management agent system 13 (318), the message identifier of the received result message is confirmed (319).

As a result of the check, if the message identifier of the received result message is not confirmed, the message is transmitted to another corresponding management agent system 317 (317).

As a result of the check, when the message identifier of the received result message is confirmed, the manager command information stored in advance is found by using the message identifier, the corresponding command processing routine is called (320), and the execution result of the ATM switching system 14 is analyzed (321). ).

As a result of the analysis, if the execution result fails, the operation result is converted into a common management information protocol (CMIP) message to transmit the execution result to the manager system 12 (326), and the failure result is transmitted to the manager through the Q interface. Transmit (327).

As a result of the analysis, if the execution result is successful, it is determined whether the root management command is confirmed (322).

As a result of determination, when the root management command is confirmed, the root information is extracted (323), and then, using the extracted information, a corresponding management object to reflect the result message is found and the attribute information of the management object is changed (325).

As a result of determination, if the root management command is not confirmed, the location information and the shape information are extracted (324), and the extracted information is used to find a corresponding management object to reflect the result message and change the property information of the management object (325).

Finally, in order to transmit the success result to the manager system 12, it is converted into a common management information protocol (CMIP) message (326), and the success result is transmitted to the manager through the Q interface (327).

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.

According to the present invention as described above, by using a standardized data structure, configuration management for various ATM switching systems and the like can be performed by one kind of TMN system without any structural changes, and the data structure is dependent on the type of configuration management information. Since the size of the data structure can be changed, there is an effect of reducing the waste of resources due to unnecessary configuration data transfer.
