The present invention concentrates and accepts a large number of signaling transfer points (hereinafter referred to as STPs) that transfer No. 7 signal information between signal points such as exchanges in a communication network, and performs common line signals in charge of the operation and monitoring of the signal network. It is about the centralized management method of the network.

In general, the signal network is the basis of the integrated information communication network (ISDN) and the intelligent network (IN), and serves to transmit signal information of other network equipment by using a highly reliable signal channel. In particular, the signaling network transmits the signaling messages that are generated in common in each independent network such as the establishment and cancellation of each subscriber line and the value-added service for general subscriber information with high reliability. In order to establish such a signal network, countries have tended to use the signal network to overcome the limitations of the signaling method in the existing telephone network or packet network and to easily accommodate various application services. Since signal network carries important signal information in communication network, high performance and high stability are required, and operation status of signal network should be monitored at all times.

Systems using a similar method in this regard include the Signaling Engineering and Administration System (SEAS) developed by Bellcore, USA, and the Operations Maintenance Center (OMC-III) of the Japanese entity (NTT). However, Belcoa's SEAS accepts ATT's 2A-STP, and does not have a graphical display function for notifying the operator of the signal network status, and the OMC-III measures the main function of traffic and performance data. There was a problem that the change table does not have a routing table.

The present invention devised to eliminate the above problems is the function of analyzing the traffic and performance data as well as the monitoring of network failures by collecting the measurement data on the utilization, availability, and performance of the signal network from a plurality of STP regularly or from time to time To provide a centralized management method for the common line signal network that consistently changes and verifies information related to signal points, signal links, signal link sets, and signal loops that are components of the signal network to each STP. There is this.

In order to achieve the above object, the present invention comprises a plurality of signal points and signal links, and includes a service control system (SCP), a signaling transfer point (STP), and a service switching point: SSP), ISDN switch, and Network Operation Management System (OS), which is connected to the signaling relay switch to perform the operation management of the signaling network (Signalling End Point: SEP) consisting of the signaling network X.25 Common network signaling network composed of a packet switching node that is in charge of exchanging links, and a general-purpose computer configured to have functions of network management unit, specification management unit, network connection unit, database management unit, system management unit, and user connection unit. In the centralized management method, when a measurement data collection request command is received from an operator, the corresponding table in the database is queried and measured. Produces a request message and delivers it to the signaling relay exchange through the network management application support element, and receives the measurement message sent from the signaling relay exchange through the network management application support element to the corresponding table of the database. In the first step of storing or transmitting to the operator, upon receiving the network operation management reference control command from the operator, the corresponding table in the database is inquired and a control message is generated and transmitted to the signaling relay exchange through the network management application support element. And a second step of receiving the response message sent from the signaling relay switch through the network management application support element and storing it in a corresponding table of the database or transmitting it to the operator. If received, the requested table is queried from the database. In the third step of transmitting the network management statistics request request from the operator, the fourth step of querying the relevant table in the database and sending the requested data to the operator. When received, the corresponding table in the database is inquired, a change request message is generated, delivered to the signaling relay exchange through the specification management application support element, and the response message sent from the signaling relay exchange is sent to the specification management application support element. The fifth step of changing the corresponding table of the database and transmitting the result of the change to the operator, when receiving a routing table check and verification request command from the operator generates a request message through the specification management application support element Deliver to signaling relay switch and send out from signaling relay switch The sixth step of receiving a response message through the specification management application support element, checking or verifying a corresponding table in the database, and transmitting the verification or verification result to an operator; Receive or confirm the corresponding table or record in the database after receiving the message, and then send the result of the check or change to the operator. Eighth step of generating a report based on the report and transmitting it to the operator, and receiving a remote direct communication request command from the operator, delivers it to the signaling relay exchange through the system management application support element, and sends a response from the signaling relay exchange. Receive messages through the system management application support element. This is performed by the seventh step of storing the data in the corresponding table of the database or transmitting it to the operator.

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

A signal network composed of many signal points and signal links plays a role in delivering signal messages to various signaling end points (hereinafter referred to as 'SEP') using a high-speed, high-reliability signal channel. SEPs include STP 101, SCP 102, SSP 103, ISDN exchange 104, and OS 105.

Looking at the signal network from the perspective of providing the service per intelligence, the Signaling Connection Control Part, the Trans-action Capabilities Application Part, the application as a means for accessing information between the SCP 102 and the SSP 103 Application Service Element protocol is used. SCP 102 maintains a database related to the intelligent network service, retrieves information related to the requested information from the database, and transmits the retrieved information to the SSP 103 through the signal network. When the STP 101 having a relay function between signal points, which is a packet switch, has a user application part, it may be a signal end point.

The SNMC 108, which performs the operation management of the signaling network, is an X.25 packet switched node that is responsible for the exchange function of the X.25 link between the STP 101 and the point-to-point. 106 and a general purpose computer 107.

The system to which the present invention is applied includes the main functions of the application support unit and the system including the network connection unit 203, the database management unit 204, the system management unit 205, and the user connection unit 206, as shown in FIG. It can be divided into an application processing unit consisting of the network management unit 201 and the specification management unit 202 can be said.

The network management unit 201 stores measurement data and monitoring data generated in the signal relay exchanges, which are the main components of the signal network, in a database, and the data is used to analyze the state of the signal relay switch and the state of the signal network. I use it.

The measurement data mainly represents the performance, availability, and utilization of signal links, signal link sets, signal roots, signal points, and signal connection controllers, and expresses performance measurements inside the signal relay switch. It is collected immediately after occurrence and from time to time at the request of the operator for maintenance purposes. The situation is notified as soon as an emergency situation such as network congestion, routing failure, or abnormal condition of the network resource exceeding the limit value is displayed, and the corresponding message is displayed in the operator's work area, indicating the overall configuration state per signal. Displayed on the graphics monitor.

When the operator wants to see the collected data, he or she can query the information in the database. Although it does not perform many functions in the control per signal, it can change the congestion limit value for traffic congestion detection and the protocol timer value of the message transfer part for control and synchronization per signal.

The specification manager 202 performs a function of changing or verifying signal network specifications in order to centralize routing tables held by each signal relay exchange to maintain overall coherence and synchronization of the signal network remotely. In this case, the signal relay switch transfers a signal message to a specific signal point based on the routing table representing the signal path. Each signal relay exchange represents and uses a signal route, which is a logical channel of a signal network, as a relationship between signal points, signal links, and signal link sets.

When there is a reason for changing the network specifications, it provides the operator with convenient methods such as menu and form management function to change the routing table. For specification management, commands and responses for adding, deleting and changing routing table specifications and retrieving each record or unit are exchanged with the signaling relay switch. The change request sent to the signaling relay is processed in substantially two ways: immediate processing and delay processing. Immediate processing is where the change is performed as soon as the change request is received. On the other hand, in the delay processing method, the change is performed when a specific time specified in the change request or subsequent successive activation commands are received.

In addition, in order to maintain the accuracy of the signal loop, a table comparison is performed between pairs of signal relay exchanges or between signal relay exchanges and local routing tables using data of the routing table inputted from the replication function of the STP 101 table.

The network connection unit 203 is connected through an X.25 packet switching node 106 serving as a signal relay switch and a front-end processor to exchange messages, and is a lower layer of the protocol, X.25. Performs processing for connection with The upper layer of the protocol consists of the Operations Message Communicatioll Protocol (OMCP) for processing messages on the packet layer providing network services. The application process receives the service of the upper layer, and the communication with the signaling relay switch is performed in the form of a promised message on the same layer. In particular, OMCP is a protocol that processes both short and long messages simultaneously. It is a protocol based on the socket of a computer and Transmission Control Protocol / Internet Protocol (TCP / IP).

The user connection unit 206 supports command input, graphic output, report generation, etc. to an operator using input / output equipment such as a CRT terminal, a personal computer, or a graphic monitor as a means for accessing and supporting the system. Form processing, input data verification, command scheduling functions are provided to support operator commands, alarm processing and network output functions are supported for graphic output, report scheduling for report generation, and report form design function are supported.

The system manager 205 supports a function of creating and maintaining various environments so that an operator can utilize various application functions provided by the system. In order for a system to enter operational status, the system's software and database must be installed, all applications must be run, and the status of running processes must be monitored. In addition, it performs management functions such as the initial installation of the system, the handling of failures that may occur in software, the supplementation or correction of software, and the management function for the communication connection between its own system and the signal network node.

Since the database manager 204 requires management of various databases, a commercial relational database management system (DBMS) is used, and a main database for signal network management includes a signal network configuration database and a routing table change data. Database, automatic output message database, periodic measurement message database, and system management database.
