Abstract

The present invention relates to message processing method, device, communication equipment and communication system. The message processing method includes: after receiving the message to be compressed sent by the local FPGA, parsing the header information of the message to be compressed and putting it into the local compression table; instructing the peer CPU through compression control signaling according to the local compression table Perform compression table synchronization; after the peer CPU completes compression table synchronization, send the compression information of the local compression table to the local FPGA. Among them, the message to be compressed is a service message for which there is no corresponding compression table record, and the header information includes IP header information and MAC header information; the compression information of the local end compression table is used to synchronize the compression table of the local FPGA, and the synchronized local The compression table of the end FPGA is used to instruct the local FPGA to perform IP header compression and MAC header compression on the packet to be compressed. The CPU and FPGA jointly implement IP header compression and MAC header compression for air interface wireless transmission messages, which greatly improves the air interface bandwidth utilization and significantly improves system performance.
