METHOD FOR COMPRESSION OF ETHERNET HEADERS, THE METHOD FOR DECOMPRESSION OF ETHERNET HEADERS AND THE DEVICE FOR COMPRESSION/DECOMPRESSION OF ETHERNET HEADERS

摘要

FIELD: computer networks. ;SUBSTANCE: invention relates to means for compression /decompression of Ethernet headers. Data is transmitted using a Packet Data Convergence Protocol (PDCP) transmitting object on the transmitting side, where the first PDCP PDU packet corresponds to the first DRB data transmission channel in such a way that if the compression function of Ethernet headers is set in the first DRB radio channel, then the first PDCP PDU packet contains one or more blocks from the first data part, which indicates whether a certain Ethernet field is used in the Ethernet header of the first PDCP SDU packet corresponding to the first PDCP PDU packet, repeatedly. ;EFFECT: providing support for compression of Ethernet headers at the level of the PDCP protocol, which performs compression of headers. ;34 cl, 13 dwg
