¿µ¹®³»¿ë¿ä¾à | This standard provides a mathematical algorithm that can evaluate/plan the quality level of a voice service that provides wideband (50~7000Hz) using network performance indicators, etc. Such a model can be usefully used to establish a plan to provide appropriate quality to users. The quality level of the voice service generally has a close correlation with the network quality, and reflects various degradation factors in the network transmission and mouth to ear path. | ||
