1. An Ethernet header compression method, applied to a transmitting end and comprising:
receiving a configuration message; wherein the configuration message comprises second information, used for indicating to configure an Ethernet header compression function of a data radio bearer DRB; and
transmitting, by using a transmitting packet data aggregation protocol PDCP entity of the transmitting end, a first PDCP protocol data unit PDU corresponding to the data radio bearer DRB; wherein
the first PDCP PDU comprises one or more pieces of first information and sixth information used for identifying a data stream corresponding to the first PDCP PDU, wherein the first information is used to indicate whether a specific Ethernet field in an Ethernet header of a first PDCP SDU is compressed, and the first PDCP SDU corresponds to the first PDCP PDU;
wherein the first PDCP PDU further comprises one or more of the following:
seventh information, used for indicating a length of bytes newly added relative to a legacy PDCP sub-header;
eighth information, used for verifying the Ethernet field; and
ninth information, used for indicating whether the Ethernet header compression function is performed on the first PDCP PDU.
