Since NO.7 signaling network transmits call control information, billing information, and operation maintenance information of communication network, network management of this signaling network is very important, but conventional No.7 signaling network management service is No.7 signaling network. It is implemented in a way that is unique to each of those developed or produced by the exchange node that is the base of the. Therefore, there is a problem that the interoperability is not guaranteed because there is no interworking between the No.7 signaling network management services and the physical and logical matching between No.7 signaling network management is not performed.

In addition, since the conventional No. 7 signaling network management service has a unique configuration scheme and a unique operation scheme, in view of the overall network management service, the network management service is not systematically configured, and the unique No. 7 signaling network management service has a unique configuration. 7 There is a problem that it is impossible to provide the overall No.7 signaling network management service because information is not exchanged between signaling network management services.

In short, conventionally, since No.7 signaling network management service has its own network management service network, it is possible to exchange network management information only in each network, and also has a hierarchical structure between No.7 network management systems and an integrated network. Since it is impossible to provide a management service, there is a problem in that the service provision range of No. 7 network management service is limited and that it is impossible to provide an integrated network management service that aggregates network management services.

1 is a configuration diagram of a TEM (TMN) functional reference model applied to the present invention, and shows a TEM (TMN) function applied to a No. 7 signal network.

TMN defines communication network management as five layers. That is, a network element layer, a network element management layer, a network management layer, a service management layer, and a business management layer. .

The network management reference model of CCS No. 7 signaling network mentioned in International Telecommunication Union (ITU-T) Recommendation Q.750 describes the lower three layers as shown in FIG.

The network element layer 103 includes a managed switching element, a management information base (MIB), and an agent.

That is, the managed system is an exchange system that is managed by the network, and the management information data (MIB) is an abstraction of the managed network resources and is a collection of managed objects.

Agent acts as an agent for the network element management layer in the manager-agent concept, which has a management object in management information data (MIB). It manages No.7 signaling network resources of exchange. Here, the resources of the No. 7 signal network are signal points, signal link sets, signal links, signal data links, signal terminals, and the like.

The network element management layer 102 operates as a manager for the network element layer to perform network element management functions. In order to manage a managed object, a network management command must be given to an agent by a management scenario in a manager function in a network element management layer.

The Manager and Agent are defined by the q3 reference point and communicate with each other by the method defined by the Q3 interface.

The network management function of the No.7 signaling network is performed by generating a network management command from the Manager to operate the network management function of the Agent No.7 signaling network.

CCS No.7 network management commands are for creation, deletion, and retrieval of signaling points and for creation, deletion, retrieval, operational status changes, management status changes, and testing of signal links.

In the network management layer 101, it is used when network management information across multiple nodes is needed and performs network management from a network perspective. In the network management reference model presented in Q.750, the function of the network management layer is to coordinate, motivate, and harmonize within the network to match signal points.

TMN uses the object-oriented technique to define managed objects, abstracts network resources to perform network management, and the set of managed objects is management information data (MIB). The network management function is performed by the control operation for the MIB.

As shown in FIG. 1, when the network management function is designed based on the network management function reference model, the following objects may be present for network management of the MTP portion of the No.7 signaling network of the ATM switch.

Point (208), Signaling Link Termination Point (signLinkTp) 204, and Signaling Terminal (signTerm) (205), and a two-way adaptive trail configuration (tcAdaptorTTPBid: Transmission Convergence with respect to ATM exchange). Adapter Trail Termination Point Bidirectional (206), Virtual Path Connection Termination Point Bidirectional (vpCTPBid) (209), Virtual Path Trail Termination Point Bidirectional (vpTTPBid) (207), and Bidirectional There is a management object such as Virtual Channel Connection Termination Point Bidirectional (vcCTPBid) 210.

The management objects related to the No.7 signal have the containment relation of FIG. 2, and the network management of the No.7 signaling network abstracts network resources into the following management objects.

The management objects MTP layer signaling point (mtpSignPoint) 202 has a unique code for distinguishing each signal point, and can be referred to as a signal point endpoint that varies values for each signal node, and is a signal link set (signLinkSetTp). 203 is a set of signal links that share a destination.

The signal link termination (signLinkTp) 204 is a conceptual signal link line that carries a signaling message as a signal link without transmission error, and the signal data link (signDataLinkTp) 208 is a physical signal transfer line, which is a circuit endpoint in network management. A management object that represents a circuit termination point, and is a management object that points to a physical connection point in an asynchronous transfer mode (ATM) in an attribute within the management object. .

A signal processing terminal (signTerm) 205 is a signal processing terminal which terminates a signal link in a network node, and is a physical processing device having a processing function for processing a message transmitted on the signal link, and a signal data link (signDataLinkTp) 208. ) Points to an ATM-related management object with path information of the ATM network through which signaling messages are delivered.

In relation to the managed objects, the MTP layer signaling point (mtpSignPoint) 202 is a managed object in a switch (managedElementR1 or managedSwitchingElement), and a managed object representing a signal link set (signLinkSetTp) 203 is connected below it. .

The management object representing the signal link termination (signLinkTp) 204 is connected to the management object representing the signal link set (signLinkSetTp) 203 and is a management object representing a signal link, and is a signal processing terminal that is in charge of processing functions. signTerm) 205 and a signal data link (signDataLinkTp) 208 that indicate the line of the signal link.

The inclusion relationship of the management object seen from the perspective of ATM network element is shown in FIG. 2, and the virtual path identification (VPI) and virtual channel identification (VCI) when using the ATM network as a physical path for delivery of MTP signaling messages. Figure 1 summarizes the relationship between ATM managed objects from the perspective of configuration for storing.

Two-way adaptive trail configuration (tcAdaptorTTP Bidirectional) 206, two-way virtual path trail configuration (vpTTP Bidirectional) 207, two-way virtual channel connection under the top managed element (managedElementR1) 201, which is a managed object representing the managed ATM exchange system. Configuration (vcCTP Bidirectional) 210, under the two-way adaptive trail configuration (tcAdaptorTTP Bidirectional) 206 is a two-way virtual path connection configuration (vpCTP Bidirectional) (209), two-way virtual path trail configuration (vpTTP Bidirectional) (207) Below, there is a managed object representing the vcCTP Bidirectional 210.

FIG. 2 is a diagram illustrating a relationship between a management object defined in No. 7 signaling network and an ATM network, and a containment relationship. Using the management objects, management information data (MIB) for network management of No. 7 signaling network is generated. By creating, deleting, modifying, and retrieving this in the agent, it performs the network management function suggested in the network management reference model.

The TMN function has its own Graphic User Interface (GUI) function, and the Graphical User Interface (GUI) terminal 304 is an F-interface Manager (301). Communicate with each other).

The manager 301 is a function module that manages overall functions for network management. The manager 301 communicates with an agent 302 as a common management information protocol (CMIP) to perform network management functions. In this case, the agent 302 creates, deletes, changes, and retrieves a management object included in the agent, and controls network management resources in the ATM switch 303.

The ATM switch 303 is provided with its own operator-switch communication means, that is, a human machine interface (HMI) function (hereinafter referred to as HMI) locally for communication with the operator.

The TMN function does not have a separate interface for communication with the exchange, and it uses the matching function of the HMI by sending commands of the HMI function through the matching function of the connector for TMN agent and ATM switching system (CAS). Communicate with the exchange.

In order to perform the network management function of the No.7 signaling network, the Manager is a network element layer in the No.7 network element management function consisting of a Signaling Point Module and a Signaling Link Module. Command to Agent located in. In this case, a protocol called Common Management Information Protocol (CMIP) is used through the Q3 interface.

Agent 302 functions as a No. 7 composed of a signal point management unit and a signal link unit to perform network element functions, and management information data (MIB) for No. 7 managed by the Agent 302. It generates, deletes, changes, and retrieves the data, and reports the execution result to the manager 301, and reports the manager 301 even when there is a change in the resource of the exchange 303. Do The managed objects managed by the Agent 302 are made by object-oriented techniques, and are configured in correspondence for management of resources of the exchange.

The Failover Charge Performance Security Management Interface (FCAPS Management IM) is one of the five major TEM majors. It handles the functions, and the network management function of No. 7 works with the exchange through the configuration function.

FIG. 4 is a flowchart illustrating a signal link generation method based on a TEM (TMN) method in an asynchronous transmission mode network according to the present invention, and shows a processing flow in a manager when generating a No.7 signal link.

First, when the network management terminal receives a message requesting the creation of the No.7 signal link (401), it checks whether the agent is in operation (402), and if the operation is not in operation, signals the No.7 signal to the network management terminal as a failure process. The link creation failure is output (404), and the following process (403 or less) is performed if it is in operation.

Requesting the creation of a signal processing terminal (sigTerm) management object to the agent, requesting the generation of signal terminal information (403), confirming the completion of the creation thereof (405), failing if it fails (404), and succeeding. If so, the agent requests creation of a management object signal data link (sigDataLinkTp) management object, requests generation of physical configuration information of the signal link (406), and confirms a creation completion response (407).

As a result of the check of "407", if it fails, it fails (404), and if it succeeds, it requests the agent to create a bidirectional virtual path connection configuration (vpCTPBid) managed object, requesting the generation of virtual path connection information (408), Confirm that the creation is complete (409), and if it fails, request the agent to delete the previously created signal data link (sigDataLinkTp) (411), and if successful, create a bidirectional virtual path trail configuration (vpTTPBid) managed object. In step 410, a request for generation of trailed virtual path connection information of the No. 7 signal link is requested (410), and the completion of creation thereof is confirmed (412).

If a check of "412" fails, the agent requests the agent to delete the previously created Signal Data Link (sigData LinkTp) managed object and the bidirectional virtual path link configuration (vpCTPBid) managed object (414); A request for creation of a channel connection configuration (vcCTPBid) management object is required to generate virtual circuit connection information of No. 7 signal link (413) and confirm creation completion thereof (15). If it fails, the agent requests the deletion of the previously created managed object Signal Data Link (sigDataLinkTp) managed object, the Interactive Virtual Path Link Configuration (vpCTPBid) managed object, and the Configure Interactive Virtual Path Trail (vpTTPBid) managed object to the agent. 417, if successful, requests the agent to create a signal link termination (sigLinkTp) management object to generate the No.7 signal link configuration information (416), and confirms the creation completion thereof (418).

If the check for "418" fails, the previously created managed object signal data link (sigDataLinkTp), two-way virtual path link configuration (vpCTPBid), two-way virtual path trail configuration (vpTTPBid), and two-way virtual channel connection configuration (vcCTPBid). The agent requests the deletion of the management object for the management object (420). If all succeeds, the network management terminal outputs the success of generating the No.7 signal link to the operator (419).

FIG. 5 is a flowchart illustrating a signal link deletion method using a TMN method in an asynchronous transmission mode switch according to the present invention, and shows a processing of a manager when deleting a signal link.

First, when the network management terminal receives the No. 7 signal link deletion request (501), it is checked whether the agent is in operation (502), and if the agent is not in operation, the network management terminal performs the failure processing of the No. 7 signal link to the network management terminal. If the agent outputs a deletion failure (504) and the agent is in operation, it requests the agent to delete the management object signal link termination (sigLinkTp) management object (503) to delete the corresponding management object of the signal link.

Next, the agent requests the agent to delete the interactive virtual channel connection configuration (vcCTPBid) managed object (505), deletes the associated virtual circuit connection information, and then configures the managed object two-way virtual path trail (vpTTPBid) managed object. Requesting the agent to delete (506) the connection information of the associated virtual path.

Next, the agent requests the agent to delete the bidirectional virtual path connection configuration (vpCTPBid) management object (507), deletes the connection information of the virtual path, and requests the agent to delete the signal data link (sigDataLinkTp) management object. 508, the physical configuration information of the signal link is deleted. Next, a No.7 signal link deletion success is output to the network management terminal (509).
