Message processing method and device, communication equipment and communication system

Abstract

The invention relates to a message processing method and device, communication equipment and a communication system. The message processing method comprises the steps that after a to-be-compressed message sent by a local end FPGA is received, header information of the to-be-compressed message is analyzed and put into a local end compression table; an opposite-end CPU is indicated to perform compression table synchronization through a compression control signaling according to the local end compression table; and after the opposite-end CPU finishes synchronization of the compression table, thecompression information of the local end compression table is sent to the local end FPGA. The to-be-compressed message is a service message without a corresponding compression table record, and the header information comprises IP header information and MAC header information; the compression information of the local end compression table is used for synchronizing the compression table of the local end FPGA, and the synchronized compression table of the local end FPGA is used for indicating the local end FPGA to perform IP header compression and MAC header compression on the to-be-compressed message. IP header compression and MAC header compression of an air interface wireless transmission message are achieved through combination of a CPU and an FPGA, the air interface bandwidth utilization rate is greatly increased, and the system performance is remarkably improved.
