METHOD AND AN APPARATUS FOR ISSUING TICKETS IN A NETWORK MANAGEMENT SYSTEM, ESPECIALLY CONCERNED WITH JUDGING DETERIORATION IN THE PERFORMANCE OF A COMMUNICATION NETWORK BEFORE AN ABNORMALITY OCCURS IN THE COMMUNICATION NETWORK

摘要

PURPOSE: A method and apparatus for issuing tickets in an NMS(Network Management System) are provided to minimize network inferiority by judging the inferiority of data inputted to an NMS from a BSM(Base Station Manager) by using threshold values and automatically issuing tickets. CONSTITUTION: A ticket issuer(30) in an NMS comprises a knowledge database(36), a collection part(34), an analysis part(38), a counter part(32), and a ticket issuing part(40). The knowledge database(36) is constructed by the call data accumulated during an appointed period. The collection part(34) collects call data. The analysis part(38) compares and analyzes the call data inputted from the collection part(34). The counter part(32) counts the output signals(BS) of the analysis part(38). The ticket issuing part(40) issues a ticket according to an output signal(TS) generated from the counter part(32).
