Error handling of useful information received via a communication network.

A method for decoding and / or detecting data containing useful information, which are received through a communication network, wherein - data received with a decoder (1) channel in a receiver (5) Communication Terminal evaluate at least partially corrected and retransmitted to a decoder (2) voice, - a decoder (2) voice, to the extent necessary, the data is decoded with error concealment and useful information is relayed a receiver (6) "Cellular Text Telephone Modem", - a demodulator (3) in the receiver (6) "Cellular Text Telephone Modem" these data are demodulated with reliability information and relayed to a module (4) error correction, - the module (4) error correction useful information obtained with respect to a sequence is scanned, a value in a text display / voice "Cellular text Telephone Modem" which indicates set data "C ellular Text Telephone Modem "is text data, when completed sequence detection error correction adapts according to information reliability and display text / voice" Cellular Text Telephone Modem "set is forwarded to the decoder (2 ) voice to suppress the error concealment at the decoder (2) voice.
