Description

System and method for network management service using primary group interface network {Method for Network Management Service By Primary Rate Interface Network In Exchanger}

The present invention relates to a network management service method using a primary group interface network in an exchange using a primary rate interface (hereinafter referred to as PRI), and in particular, using a primary group interface network physically connected between the exchanges. The present invention relates to a network management service system and a method using a primary group interface network, which can maintain a state of another exchanger connected to a primary group interface by using an operation management system connected to a primary switch interface.

Conventional exchange management is referred to as the Man Machine Language (MML) terminal or Graphic User Interface (GUI) according to the interface (Interface: SIO or LAN or other) environment provided by the exchange system. It is done by the program. An MML terminal or GUI (PC) program can manage only the information of the exchange directly connected to it.

In case of managing information of other exchange, Serial Input / Output (hereinafter called SIO) directly manages the information by connecting a PC with a terminal to the SIO port of the corresponding exchange. In this case, a TCP / IP reconnection must be made using the IP address of the exchange to reconnect to the logical exchange with the logical exchange.

That is, simultaneous management of multiple exchanges must be used by connecting an operation maintenance system (hereinafter referred to as OMS).

1 shows a form of operation and maintenance (hereinafter referred to as OAM) of a general exchange.

Referring to FIG. 1, a form of a system operation application made through an SIO and a LAN, which are input / output interfaces provided by an exchange system, is illustrated.

When the management of the exchange system is to be performed using the MML code, the function code and data value input from the terminal 110 are transmitted to the SIO interface in the form of a character string (ASCII). The message processing unit 101 analyzes the input message value and transmits it to the data processing unit 102, and the data processing unit 102 performs data processing corresponding to the command code, and transmits the result to the SIO interface. Send to the user terminal 110 through.

If the user wants to perform the exchange management using the PC 120 in which the GUI application is embedded, the system operator performs data management on a data management screen configured as a GUI. The PC application 120 transmits the data processing message to the network processing board 103 of the exchange system through the LAN port of the PC. The following processing is performed in the same manner as in the case of the SIO interface, and the message processing unit 101 analyzes the input message value (Vaule) and delivers it to the data processing unit 102. The data processing unit 102 performs data processing corresponding to the command code and sends the result to the GUI application 120 of the user through the LAN interface 103-2.

The above procedure shows the OAM processing procedure of a general exchange. The important point is that it only works with MML terminals and GUI programs connected one-to-one with the exchange.

The problems of this prior art are as follows.

In the conventional exchange, there is a problem that additional cost is required because a separate dedicated line configuration is required.

OMS is also managed through a direct one-to-one connection of exchanges.

In order to manage a plurality of exchanges, a previously connected connection must be released.

In addition, when managing multiple exchanges, there are distance, location, and time problems.

In addition, there is a conventional problem that the ability to respond to the generation of important information generated in a specific exchange is weak.

Accordingly, an object of the present invention is to provide a network management service method using a PRI network in one exchange.

Another object of the present invention is to provide a method for maintaining a state of another exchange connected to a PRI network using an operation management system connected to one exchange using a PRI network physically connected between the exchanges.

According to an aspect of the present invention, there is provided a network management service system using a primary group interface network, comprising: an operation management system for receiving an inquiry request message from a user and outputting a result message; and an inquiry request transmitted from the operation management system. Analyzing the message, if the inquiry request message is a message for an exchange other than an exchange connected with the operation management system, transmitting the inquiry request message to a destination exchange through the primary group interface network; Receiving a result message from a destination exchange and transmitting the result message to the operation management system, and if the inquiry request message is a message for an exchange connected with the operation management system, generating a result message and transmitting the result message to the operation management system. Characteristic In addition, the present invention is a network management service method using a primary group interface network in a system equipped with a motion management system and a plurality of exchanges, the analysis result when the inquiry request message is received from the operation management system, the analysis result If the inquiry request message is not a message for a currently connected exchange but a message for another exchange, the inquiry request message is transmitted to the destination exchange through the primary group interface network, and the result is transmitted from the destination exchange to the destination exchange network. Send a message to the operation management system. Here, the request message includes a number of an exchange that initiates a current request and a number of an exchange to which the request is to be made.

In addition, the present invention further includes the response message transmitted to the network-related message processing unit of the central processing module again checks whether the current response message is for the current exchange, and if not, transmits it to another exchange through the primary group interface network again. Characterized in that.

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

2 is an overall structural diagram according to the present invention.

First, the present invention uses a PRI network that is physically connected between exchanges in an exchange network using PRI.

PRI is an ISDN user-network interface for primary group access subscribers. The primary group access subscriber is a high-capacity business subscriber with facilities such as a digital automatic branch exchange or an on-premises information communication network, and a 23B + D primary group transmission structure composed of a combination of 23 B channels (64kbps) and 1 D channel (64kbps). Subscribers provide 1.544 Mbps of capacity, or 30B + D primary group access structure consisting of a combination of 30 B channels (64kbps) and 1 D channel (64kbps) providing 2.048Mbps capacity. Access to the switching center of the network provider through a subscriber line (Europe, Korea). The physical, electrical and logical specifications of the interface are specified in the ITU-T Recommendation 1.400 series. A plurality of subscriber station devices such as telephones, PCs, workstations, and fax machines share a PABX or LAN, and the PABX or LAN connects to a network provider's switching center via a network termination device.

The network management service according to the present invention is used to mean that all exchangers connected to the network are managed from one exchange by configuring several exchanges as a network.

Operation And Maintenance (hereinafter referred to as OAM) collectively refers to all the operations to operate and manage the exchange.

Central Processing Module (hereinafter called CPM) is a board used for the exchange, which stores and manages all data used by the exchange, and periodically diagnoses the status of nodes and charges terminals or billing devices or voice for maintenance. Function to provide an interface with additional devices such as mailboxes.

Local Switching Module (hereinafter referred to as LSM) is a board used in the exchange ARIEL system. It is a processor call processing and maintenance function that performs the basic functions of the exchange performed by node. It manages resources.

Each exchange needs its own unique site number.

When OMS wants to inquire information of other exchange connected with PRI network, it sends request message by using individual site number.

If the request message is another exchange other than the current exchange, the network management service (hereinafter referred to as NMS) processing units 211-1 and 222-2 are delivered to the exchange of the desired destination via the PRI network.

In the case of the response message as well, the original message is delivered through the PRI network to the exchange to which the original message has been delivered.

The OMS-related message processing units 212-3 and 221-2 are blocks that receive messages from the OMSs 230 and 240 or deliver messages to the OMS 230. If the message is not a message for the current exchange, the NMS The message per line is passed to the related message processing units 211-1 and 222-2.

The NMS related message processing unit 211-1 is a block for receiving or transferring a message from another exchange, and the OMS related message processing units 211-2 and 221-2 and the PRI related processing units 212-1 and 222-1. You will exchange messages with

3A to 3C show examples of network diagrams according to the present invention.

In addition to the example of FIG. 3, the network structure may be changed according to a user's intention.

A process of delivering a request message according to the present invention to another exchange (target exchange) through a PRI network is as follows.

First, the OMS 230, 240 selects a site to be inquired and transmits an inquiry message to the switches 210 and 220 connected by TCP / IP.

Next, the OMS-related message processing units 211-1 and 221-2 of the central processing module 211 and 221 analyze the transmitted message and the OMS-related message of the local switching module 212 and 222 when the message is for a currently connected exchange. The message is transmitted to the processing units 212-3 and 222-3, and the message is transmitted to the NMS related message processing units 211-1 and 221-1 of the CPMs 211 and 221.

Next, the message delivered to the NMS related message processing units 211-1 and 221-1 of the CPMs 211 and 221 is NMS related message processing units 212-2 and 222 of the LSM 212 and 222 through message processing. Is passed to -2).

Next, the request message delivered to the NMS-related message processing units 212-2 and 222-2 of the LSMs 212 and 222 is converted into a message that can be processed by the PRI-related processing units 212-1 and 222-1 and the PRI processing unit. To pass.

Next, the PRI related processing units 212-1 and 222-1 are transferred to the PRI related processing units 212-1 and 222-1 of the desired destination exchange through the PRI network.

Next, request messages arriving at the PRI-related processing units 212-1 and 222-1 of the destination exchange are forwarded to the NMS-related message processing units 212-2 and 222-2 of the LSMs 212 and 222.

Next, the request message transferred from the NMS related message processing units 212-2 and 222-2 of the LSMs 212 and 222 back to the NMS related message processing units 211-1 and 221-1 of the CPMs 211 and 221. After the NMS-related message processing units 211-1 and 221-1 of the CPMs 211 and 221 confirm that the request message has arrived at the current destination exchange, the OMS of the CPMs 211 and 221 is the target exchange. The message is transmitted to the related message processing units 211-2 and 221-2. On the contrary, if the current exchange is not the desired exchange, the exchange is transferred back to the NMS-related message processing units 212-2 and 222-2 of the LSMs 212 and 222 to be transferred to another exchange through the PRI network.

Next, request messages arriving at the OMS-related message processors 211-2 and 221-2 of the CPMs 211 and 221 are transmitted through the OMS-related message processors 211-2 and 221-2 of the CPMs 211 and 221. Generate a result message.

Finally, the resulting message now needs to be sent back to the exchange that was originally sent over the PRI network.

On the other hand, the transfer process of the result message according to the present invention to the original exchange (start exchange) through the PRI is as follows.

After completing the above process, the response message is transmitted to the exchange in which the original request came in the same process as the request message.

Next, the response message delivered to the NMS-related message processing units 211-1 and 221-1 of the CPMs 211 and 221 of the original starting exchange again checks whether the current response message is for the current exchange. The transmission is transmitted to another exchange again, and when it is corrected, the message is transmitted to the OMS-related message processing units 211-2 and 221-2 of the CPMs 211 and 221.

Subsequently, the response message arriving at the OMS-related message processing units 211-2 and 221-2 of the CPMs 211 and 221 transmits the response message to the OMSs 230 and 240 that originally made the inquiry request through the TCP network.

This completes the process from request to response.

The OMS or MML terminal initiating the request must send the request message with the number of the exchange that initiates the current request and the number of the exchange to which the request is made. You will need a screen to manipulate the exchange number on the OMS or MML terminal.

Each exchange needs a database that stores its own unique number and the PRI link number it will send.

In OMS receiving a response, the currently forwarded response message must show the forwarded exchange number.

In addition, it can be managed at the central exchange of alarms, fault-related messages or billing messages of individual exchanges.

As described above, the present invention can manage the state of all connected systems in one place using one OMS.

Therefore, the present invention can maintain the state of another exchange connected by PRI using OMS connected to one exchange.
