Patent ID: 7203637

Claim:
A method for transmission, in real time, of a speech block having a first bit rate containing parameters representing the data in a corresponding segment of a digitally represented data stream, comprising the steps of compressing said speech block in an encoder at a first node, whereby a second bit rate, being considerably lower than the first bit rate, is obtained, supplying error discovering encoding in the encoder at the first node, after the compression, whereby the compressed speech block obtains a third bit rate, being slightly higher than the second rate, sorting positions of speech parameters in said compressed speech block according to importance; sending the compressed speech block through a transmission chain comprising a radio link (RL) and a statistically multiplexed packet-oriented link, wherein said radio link and said packet oriented link are connected via a radio base station (BTS) in a mobile radio network (PLMN); decompressing the speech block at a second node, whereby the first bit rate is regained, comparing, at the second node, parity bits associated with said speech block for discovery of errors in the data stream, wherein at least one of the first and second nodes is part of the mobile radio network (PLMN).
