ABSTRACT:
An apparatus and method for switching a voice codec of a mobile communication terminal are disclosed. The mobile communication terminal includes various types of voice codecs, and when the terminal requests a voice call between different types of communication systems, the communication network provides information on a type of the voice codec of a destination terminal to the terminal. Then, the terminal selects a voice codec corresponding to the information on the type of the voice codec of the destination terminal and transmits/receives voice data to/from the destination terminal through the selected voice codec. Thus, a transcoding process does not need to be performed on the voice data between the origination terminal and the destination terminal, and accordingly, voice quality can be enhanced, a delay of a voice transfer can be reduced, and a load of the communication network can be reduced.
