SYSTEM AND METHOD FOR FRAGMENTED IPv4 HEADER COMPRESSION WITH ROBUST HEADER COMPRESSION IN A DATA COMMUNICATION NETWORK

原文（中国語）

A communication system and method for receiving a datagram with an uncompressed IPv4 header at a ROHC compressor in the communication system and compressing the uncompressed IPv4 header using the ROHC compressor to form the datagram with the ROHC header. The compressing by the ROHC compressor includes setting a flag in a dynamic part of an initialization and refresh (IR) packet of the ROHC header indicating that a ‘more fragment flag’ (MF) bit and a non-zero ‘fragment offset’ field are present in the ROHC header, as well as appending the MF bit and the non-zero ‘fragment offset’ field at an end of the IR packet.
