TRAFFIC DISCRIMINATION DEVICE AND METHOD FOR UPDATING THRESHOLD IN TRAFFIC DISCRIMINATION DEVICE

摘要

PROBLEM TO BE SOLVED: To make it possible to update a threshold, which is used in discriminating traffic status of a user in a communication network, according to an increase in communication demand of the user by enabling the threshold to be determined without specifying a particular value previously or storing/retaining all of past traffic amount.;SOLUTION: When the discrimination result of traffic amount X of a user per unit time by comparing with a threshold T is low demand traffic (s3; YES); parameters N1, M1, and D1 for the low demand traffic are updated (s4 to s6). When the discrimination result is high demand traffic (s3; NO); parameters N2, M2, and D2 for the high demand traffic are updated (s7 to s9), and the threshold T is updated by using only these parameters (s11).;COPYRIGHT: (C)2012,JPO&INPIT
