In the present invention, to manage the header information of the subscriber address in the network element management layer of the telecommunications management network for the ATM switching network, a management object which is a management information transmission means between the manager and the management agent of the telecommunications management network is modeled. In addition, according to the defined management object modeling, it is possible to manage subscriber address header information for an ATM switch through interworking between a manager of a telecommunication management network and a management agent. That is, in the present invention, the subscriber address header information of the ATM switch is defined as a management object class in order to interconnect the manager and the management agent of the telecommunication network and enable the interworking operation between the two systems. It defines the association with subscriber address header management resource and operates between manager and management agent for subscriber address header management according to defined association. According to the present invention, subscriber address header information can be consistently managed at a remote location by the integrated network management operator without having to manage individual subscriber address header information of the local operator of the ATM switch.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a structural diagram showing a relationship between a telecommunications management network (TMN) manager system 102 and a management agent system 108 for managing an ATM switch to which the present invention is applied.

The manager system 102 and the agent system 108 of the telecommunications management network (TMN) are each located in separate workstations 101 and 107. The manager system 102 existing in the workstation 101 for the manager system has a function of transmitting information between the main manager 103 and the manager agent who are in charge of the interface with the TMN operator 106 and various management functions of the manager system. Open Systems Interconnection (OSI) is responsible for the protocol stack (OSI) (Stack) 104 and the management function that is responsible for administrator-specific functions, the management function of the administrator includes a configuration management function (including the present invention) 105) is also included.

The management agent system 108 present in the workstation 107 for the management agent system is a network element agent subsystem (NEAS) for carrying out management messages from the administrator (109) and for information transmission. OSI protocol stack, Connector for Agent and Switch Subsystem (CASS) 111, which manages connections to ATM exchangers, and resources of ATM exchanges. It consists of a Management Information Base (MIB) 110 expressed as an Object.

On the other hand, the command of the TMN operator 106 is transmitted between the manager and the management agent using the Common Management Information Protocol (CMIP) 112 of the application layer, and the command is applied to the ATM switch 112. Communication between the manager and the management agent is physically performed through a data communication network (DCN) 113.

FIG. 2 is a table in which subscriber address header information of an ATM switching network to which the present invention is applied is defined as a managed object class that can be managed in a telecommunications management network.

In telecommunications management network, the resources to be managed are modeled as management object classes. The management object class 201 consists of various packages 202, and the package consists of a mandatory package that must be included in the management object class and a conditional package that can be optionally included. The package consists of 202 attributes 203, which represent the detailed characteristics of the managed resource. In the present invention, three types of managed object classes, five types of packages (one required package, four optional packages), and five attributes are defined.

The management object class applied to the present invention includes a carrierData 204 representing a network operator resource, a prefixDigitAnalysisR1 205 representing a subscriber address header information resource, a listOfRouteTps 206 representing a routing scenario resource, and a routing scenario. There is a virtual path group (virtualPathGroupR1) 207 that represents the root resource.

carrierData 204 is based on the carrierData management object class defined in Q.824.6, which represents the network operator's unique number and the carrier's identification code, and carrierTypePkg () is an optional package for expressing the types of networks classified by network operators. 208) and userLabelPkg (209), which is an optional package representing each name of the separated network, is added and defined. Since the use of the selected package of the managed object class is determined according to the unique characteristics of the managed system, the extended definition is defined by adding two optional packages to the carrierData representing the network resource defined in Q.824.6. In addition, the listOfRouteTps (defined in Q.824.6) management object class that represents the routing scenario resource is defined by adding carrierTypePkg (216), which is an optional package that expresses the type of network to be routed. In addition, the prefixDigitAnalysisR1 (205) managed object class expressing subscriber address header information includes the required package prefixDigitAnalysisR1Pkg (210) in addition to the prefixDigitAnalysis managed object class defined in Q.824.6, userLabelPkg (211) and listOfRouteTpsPtrPkg (212) as optional packages. Redefine by adding carrierTypePkg (213), internalTrunkCodePkg (214), and prefixStatePkg (215).

prefixDigitAnalysisR1Pkg (210) is composed of header type and attributes representing minimum and maximum incoming digits. listOfRouteTpsPtrPkg 212 includes an attribute representing a list of network operators and corresponding routing scenario numbers. The internalTrunkCodePkg 214 is used to distinguish each of them when the same station code header information includes several area code header information. The prefixStatePkg 215 is defined to provide a change history service when specific station number header information is changed to other station number header information.

Finally, the virtualPathGroupR1 207 management object class is used for reference only to refer to the root number corresponding to the routing scenario in the present invention, and a detailed description thereof will be omitted.

3 is a diagram illustrating a mutual inclusion relationship between management object classes for managing subscriber address header information in a telecommunications management network according to the present invention.

The ATM switch managed by the present invention is located at the top of the managed element object class (managedElementR1) defined in ITU-T M.3100, and includes carrierData management object class 302 and subscriber address header information for managing network operators. PrefixDigitAnalysisR1 (303) for managing, listOfRouteTps (304) for managing routing scenarios, and vpGroupR1 (305) for representing route information for reference.

prefixDigitAnalysisR1 303 has a relationship with listOfRouteTps 304 using the listOfRouteTpsPtr 212 attribute of FIG. 2. listOfRouteTps 304 refers to the corresponding vpGroupR1 305 management object instance information using listOfRoutesPtrList among the attributes.

4A and 4B are flowcharts illustrating an execution procedure for managing subscriber address header information between a manager system and a management agent system of a telecommunications management network for managing an ATM switch according to the present invention.

The header of the subscriber address is composed of network operator information, country code information, area code information, and area code. That is, address header management is possible through control of each of these components. The manager receives an address header information management command from the TMN operator (401). The administrator determines what kind of address header is required (network operator, country code information, area code information, local country code) (402), and whether the management of information requested by the operator is addition or deletion of header information. In operation 403, it is determined whether the information change request is requested.

As a result of the determination, in the case of addition to the header information, the routing scenario number and the type of network operator must be checked among the input parameters set by the operator. The manager requests 404 a routing scenario search to check whether there is a scenario number that can be routed for the header type to be added to the management agent, and receives a response 405. If the corresponding routing scenario exists (406), the administrator checks whether the network operator corresponding to the routing scenario is set as a management agent (407, 408, 409), and if there is a network operator, generates the header information requested by the operator. In step 410, the management agent requests to create an instance of the subscriber address header information management object class (prefixDigitAnalysisR1). However, if there is no routing scenario information or network operator information, the management agent sends an error response to the manager (412), and the manager transmits a failure response to the TMN operator (413).

On the other hand, if the change management type is deletion for the header information (403), the management agent requests the deletion of the instance of the subscriber address header information management object class (prefixDigitAnalysisR1) (414). Analyze the change information (415) of what one change is (header name or network type or routing scenario number or minimum / maximum number of digits), and use the corresponding agent in the instance of the subscriber address header information managed object class (prefixDigitAnalysisR1). A request for a property change is requested (416), and then the result is waited for.

The management agent receives each command for each change management type from the manager (411), classifies the address header change type (417), and if so, transmits an address header addition command to the exchange (418). In case of deletion, an address header deletion command is transmitted to the exchange (423). In case of information change, an address header information change command is transmitted (427) to the exchange, and then a result response is waited for from the exchange (419, 424). 428).

If a normal result is returned from the exchange, if the header is added, an instance of the subscriber address header information managed object class (prefixDigitAnalysisR1) is created in the management agent MIB (420), and if it is deleted, the instance is removed (425). If it is a change, the property that requested the change is reflected in the property of the instance (429). When the result reflection is completed, the manager is notified of the completion (421, 426, 430), and the manager responds (422, 431) the result to the TMN operator and ends. If a failure response is received from the exchange, the management agent responds 432 to the failure to perform as an administrator, and the administrator terminates after responding 433 to the TMN operator.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes can be made in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.

In the present invention made as described above, a management object class is defined to manage a subscriber address header in a telecommunications management network, and a subscriber address header management resource of an ATM switch and a management object class that can be managed in a telecommunications management network. Correlation was defined. Through this, subscriber address header information can be exchanged between manager and management agent of telecommunication management network, so that integrated network management is possible. As a result, an integrated network management operator can remotely control multiple ATM exchanges without having to rely on ATM operators' local operators, ensuring that the data is much more consistent than those managed by individual regional operators. The subscriber header can be managed for the ATM switch, thereby providing convenience to the operator.
