Abstract
An apparatus and method of variable bandwidth multi-codec quality of service (QoS) control are provided. The apparatus for controlling the QoS of a variable bandwidth multi-codec includes: a network state detection unit detecting a network state including at least one of a packet loss ratio, a packet loss interval, and a packet delay time based on an RTP packet transmitted to and received from a destination for which a call connection is established; and a codec control unit updating a transmission rate by comparing the detected resultant value with an already set reference value and increasing or decreasing the transmission rate, and controlling the variable bandwidth multi-codec to code data with the updated transmission rate. According to the apparatus and method, data can be coded with a codec transmission rate suitable for a network state identified during a voice call after the call is set up.
