Abstract
A method and apparatus for controlling a variable bit-rate voice codec are provided. The method of controlling the variable bit-rate voice codec may include: extracting calling capability of terminals that request a new call to be made; extracting network parameters from existing calls in the network through an exchanged packet; measuring voice quality of the existing calls based on the extracted network parameters; and determining whether to permit a new call to be made based on the measured voice quality and the calling capability. Accordingly, it is possible to secure QoS of a voice service between terminals by adjusting a transmission rate of the variable bit-rate codec based on transmission capability of a network.
