Abstract

PURPOSE: A method for extracting fault line connection details in a communication network is provided to extract line connection details using a transmission facility database, a line database and a fault database in order to rapidly catch the flow of damage status due to a fault generated on a line. CONSTITUTION: If a fault line is generated in a communication network(202), a fault line connection details extraction system receives it through an operator or a centralized operation and maintenance system and judges whether the fault line is an optical terminal, a DS3-class line or a DS1-class line(203). In case that the fault line is the optical terminal, the system gets detailed optical cable connection information(204). If the fault line is the DS3-class line, the system gets the detailed connection information of an optical terminal pass(205). In case that the fault line is the DS1-class line, the system gets the connection details information of a DS3-class pass(206). If the connection details of the fault line are obtained, the system gets a detailed breakdown of transmission devices using a transmission facility database(207). In case that a fault alarm has been generated from the transmission devices, the system obtains various information for the fault using a fault database(208). Finally, the system generalizes and displays the connection details of the fault line, transmission device detailed information and fault information(209).

1 is an exemplary configuration diagram of a system for extracting a failure line detail connection of a communication network to which the present invention is applied.

When the operator 101 directly inputs a failure line or inputs a failure line in a centralized operation maintenance system such as a synchronous transmission network management system (MOST) 102, the operator 101 receives the failure line and receives the transmission line database 104 and the line database 105. Search for and analyze the details of the fault line connection.

Thereafter, the transmission facility database 104 is searched to obtain detailed information of the transmission apparatus included in the detailed connection history. Then, the failure database 106 is searched for the failure of the transmission apparatus and the necessary failure alarm is obtained. Finally, the detailed information of the fault line collected, the details of the transmission device, and the fault information are collectively displayed on the screen.

First, a connection with the centralized operation maintenance system or an initialization operation for searching a database is performed (201).

Check if a fault line occurs in the communication network, and if a fault line occurs (202), it is received through the operator or the centralized operation maintenance system, and the line name assigned to each signal level and facility layer is analyzed to determine whether the fault line is an optical end station. In step 203, it is determined whether it is a DS3-class line or a DS1-class line.

As a result of the determination (203), if the fault line is an optical end station, information on the optical cable connection information (optical cable name, core line number, water transmission segment, relay section number, patch section number) constituting the optical end station is obtained (204). If it is a DS3-class line, as shown in FIG. 3 to be described later, the connection history information of the optical end station path constituting the DS3-class line is obtained (205). If the fault line is a DS1-class line, it is shown in FIGS. 4A to 4C described below. As described above, connection history information of the DS3-class path constituting the DS1-class line is obtained (206).

When the connection details of the fault line are obtained as described above, the details of the transmission devices (optical cable, optical station, multiplexing device, DXC) included in the connection details using the transmission facility database 104 (device model, slot number, Bay, self, cross connection, etc.) are obtained (207).

Thereafter, when a failure alarm occurs in the transmission apparatuses, the failure database 106 is used to obtain information on the current failure state, the highest failure state, the location of the failure, the occurrence time, the failure period, and the number of failures (208).
