FIELD: transmission of packet data in communication system, in particular, system and method for transmitting packet data which contain header information.
SUBSTANCE: in accordance to the invention, transmission of a packet with full header or compressed header is determined in accordance with lower level report and preferably independently from any request from receiving device. The determining is preferably conducted at the level of packet data convergence protocol, and radio channel control level protocol level acts as lower level. In one example of realization, attachment of full header to a packet is launched on message of radio channel control level protocol level about error of transmission of previous packet. In another example of realization, one of triggers for attachment of full header to a packet is excluded on message of radio channel control level protocol level about successful transmission of previous packet with full header. Transmission of packets with full headers is preferably controlled on basis of lower level information through check connection channel. Aforementioned information defines whether the transmitted packet with full header was successfully received by receiving device.
EFFECT: increased speed of packet transmission and efficiency of system and method for controlling transmission of packets in communication system.
