Filed: 2001-12-22
Abstract: PURPOSE: A method for processing and managing data of a user interface service in an NMS(Network Management System) is provided to reduce a load of a GUI(Graphic User Interface) server and shorten execution time over an alarm-related request by minimizing a traffic of a network. CONSTITUTION: When an alarm is generated from an equipment, an alarm report event is executed, and alarm information is transferred from the equipment to a server alarm manager of an EMS server(S310). The server alarm manager initiates an alarm report event processing procedure and judges whether the alarm reported from the equipment has been duplicated(S321,S322). If the alarm report has been duplicated, the server alarm manager checks whether the corresponding alarm is released(S323). If the alarm is not released, the server alarm manager checks whether pre-set time is out(S324). If the pre-set time is out, the server alarm manager completes the corresponding event processing procedure(S324). If the alarm has not been duplicated(S322), the server alarm manager updates an alarm table with the received alarm information and stores the alarm information in a database(S325,S326). An alarm with a priority to be first processed is set as a representative alarm, and whether the representative alarm is changed(S327). The server alarm manager informs a user interface that the event alarm has been reported and the representative alarm has been changed, for an operator's recognition(S330,S340). When an alarm synchronization event is generated and transferred from the equipment, the server alarm manager checks a serial number of the corresponding alarm to check whether the serial number has been changed(S350,S351). If the alarm serial number has been changed, the server alarm manager updates the alarm table according to the alarm information and updates the alarm information in the database(S352,S353).
