SPEECH TRANSMISSION IN A PACKET NETWORK |
摘要 |
Speech is transmitted between a base station (BTS) and a TRAU by converting a speech signal into a parameter group which is inserted in a traffic frame which is transmitted as a packet comprising a header and a payload. In accordance with the invention, the payload is formed of the contents of several traffic frames until the payload is essentially full, and a packet is sent to the destination via the transmission network. At the destination the traffic frames are separated from the payload of the received packets and they are passed to a speech decoder. The packing of packets full can be started about a second after the beginning of the connection and after pauses, in which case the ending of a pause is transmitted to the listener as fast as possible. |
