FIELD: technology for transferring packet data in communications system.
SUBSTANCE: in accordance to invention, packet transfer with full header or compressed header is selected depending on low level report and preferably independently from any request from receiving device, preferably selection is performed at the level of packet data convergence protocol, and the lower level is set at radio link control protocol, in one example of realization, connection of full header to the packet is started on message of radio link control protocol about error during transfer of previous packet, in another example of realization, one of triggers of connection of full header to packet is excluded on message of radio link control protocol about successful transfer of previous packet with full header, while transfer of packets with full headers is preferably controlled on basis of lower level information via reverse communication channel, this information indicates whether a previously transferred packet with full header was successfully received by the receiving device.
EFFECT: creation of efficient packet data transfer method ensuring high transfer speeds.
