Patent ID: 8675497

Claim:
A communication quality evaluation system for evaluating communication quality of a communication system, comprising: a map or layout diagram display device which displays a map or a layout diagram of a specified area in a communication network for a wireless communication system; a control unit which displays the map or the layout diagram of the specified area on the map or layout diagram display device in accordance with an instruction by an evaluator; a position specifying device which specifies a plurality of evaluation points for which the evaluator evaluates the communication quality, within the map or the layout diagram shown on the map or layout diagram display device; a network quality estimation unit which estimates network quality when communications are performed between the plurality of evaluation points specified by the position specifying device; wherein the network quality estimation unit includes: a radio wave environment database in which radio wave environment data indicating radio wave environments of respective locations are stored while being associated with the respective locations; a traffic database in which traffic data indicating traffic volumes of respective locations are stored while being associated with the respective locations; and a quality parameter calculation unit which calculates a quality parameter for estimating the network quality, and the quality parameter calculation unit extracts radio wave environment data corresponding to the evaluation points from the radio wave environment database, extracts traffic data corresponding to the evaluation points from the traffic database, and calculates the quality parameter based on the extracted radio wave environment data and the extracted traffic data to estimate the network quality at the evaluation points; a quality simulation unit which deteriorates evaluation data to be used for evaluating communication quality according to the network quality estimated by the quality estimation unit, and outputs the deteriorated evaluation data; and an evaluation device which receives the deteriorated evaluation data from the quality simulation unit, and outputs the deteriorated evaluation data to the evaluator and obtains evaluator perceived quality for the deteriorated evaluation data from the evaluator.
