Abstract
Although the pursuing of the data service diversity has become the mainstream, the speech quality is of vital importance for the network operator in the intensifying competition telecommunication market. The Adaptive Multi-Rate (AMR) codec mode, which is one of the most significant techniques, is recommended by 3rd Generation Partnership Project (3GPP) for audio data compression. Many studies relevant to AMR codec, including the parameter configuration, have been progressed. However, most of them are studied by simulations. In this paper, the study of the configuration of Threshold (THR), Hysteria (HYST) and Initial Codec Mode (ICM) for AMR-FR and AMR-HR are implemented in the commercial network. Totally, 26 schemes are put forward and tested to obtain the optimization configuration, which will be used in the current network to improve the speech service quality.
