摘要

PROBLEM TO BE SOLVED: To manage and control user's body sensory quality which is effective in the whole service.;SOLUTION: In a quality management apparatus 3 and a quality control apparatus 4, an encoded quality value is calculated for each quality between connected communication terminals 1 (to ground). Quality between the communication terminals, of which the encoded quality value is an encoded quality threshold or more, is set as a quality estimation target, the present user's body sensory quality (quality estimation value) of the quality estimation target is calculated and the present user's body sensory quality (total quality estimation value) of the whole service is calculated on the basis of the quality estimation value. When the total quality estimation value is less than a total quality threshold, a predictive value (predictive quality value) of the user's body sensory quality after the quality control of the quality estimation target is calculated, a quality control target is selected from the quality estimation targets on the basis of the predictive quality value, and the priority of quality control is determined. The user's body sensory quality of the quality control target is controlled in accordance with the priority.;COPYRIGHT: (C)2007,JPO&INPIT
