Method and device for transforming a series of data packets by means of data compression

The invention relates to a through encoding or reducing (p-type) converting data packet method and device. The source data packet (11-15) is used for transmitting the data packet (21-23). In turn to obtain the data transmission packet's best filling rank, based on the invention, a data transmission packet's data area is comprises a logical channel (e.g. A data). Finally, logical channel (A and B)…The transformer data filled in parallel preferably buffer is. The arranging information without comprises a transmitting data packet data area; and with necessity; the information sent and time of. The invention suitable for with the x.25 network.
