摘要：
A method for measuring voice quality in a wireless communication network includes measuring an MOS of a signal using a narrowband voice codec and an MOS of a signal using a wideband voice codec in a cable loopback environment, calculating a wideband voice codec correction coefficient using the measured MOS, measuring an MOS of a signal using the narrowband voice codec and an MOS of a signal using the wideband voice codec in a terminal connection environment; and outputting a value obtained by adding the wideband voice codec correction coefficient to the measured MOS in the terminal connection environment.
