Summary:The invention relates to a method for improving the packet data transmission rate of a TETRA system. The method is characterized in that when a first data packet is sent between an MS and a PDC, two communication parties locally establish a connection address learning table, fixed or regularly-changed information in a data packet header domain is stored, and after the learning table is successfully established, complete UDP data does not need to be sent any more in subsequent data sending, only the data part which is changed compared with the previous data packet needs to be sent, and the receiving end recovers the compressed data according to the locally stored header field information of the previous data packet, constructs a complete UDP data packet and submits the complete UDP data packet to an upper-layer application. According to the TPDCP protocol, on the premise that a TETRA standard packet protocol is not violated, the IP header and the UDP header are compressed, transmissionof repeated information i
