Abstract
Communication systems and communication methods are provided, by which load of a communication network when measuring a voice communication quality can be suppressed. A test signal for voice communication quality evaluation is transmitted to a communication terminal apparatus via a communication network, and a received voice data encoded by a predetermined scheme for the test signal received with the communication terminal apparatus is received from the communication terminal apparatus. A received voice signal is generated from the received voice data received from the communication terminal apparatus, and a evaluation value of voice communication quality is calculated by comparing the generated received voice signal with the test signal before transmitting.
