Abstract

　既存の無線通信システム・インフラ、チャネルコーデック、誤り訂正・検出機能をそのまま使用しつつ、ダウンロードした音声コーデックを用いて音声符号化を行う通信端末装置。この通信端末装置では、判定部（１０３）において、基地局装置（１６０）の配信用コーデック格納部（１６１）からダウンロードした音声コーデックソフトウェアのビット数が、端末固有の音声コーデックソフトウェアの対応する符号化パラメータのビット数以下であると判定した場合には、コーデック制御部（１０４）は、配信用コーデック格納部（１６１）からダウンロードした音声コーデックソフトウェアを用いて、マイク（１０５）から入力される音声の符号化を行う。
