发明名称 Method for transcoding audio signals, transcoder, network element, wireless communications network and communications system
摘要 The invention relates to a method for transcoding audio signals in a communications system. In order to improve the inter-operability between units ( 2,40 ) capable of handling wideband audio signals and units ( 3,46 ) or network components ( 50 ) capable of handling narrowband audio signals, it is proposed that first, an audio signal is received in a network element ( 42 ) of a communications network via which said audio signal is transmitted. Next, it is determined in said network element ( 42 ) whether a transcoding of the received audio signal is required. In case a narrowband-to-wideband transcoding of the received signal is required, the received narrowband audio signal is transcoded into a wideband audio signal in the network element ( 1,42 ). The generated wideband audio signal is then forwarded to the receiving terminal ( 2,40 ). The invention equally relates to a corresponding communications system and its components.
