METHOD AND DEVICE FOR THE RELIABLE TRANSMISSION OF DATA PACKET FLOWS WITH COMPRESSED HEADERS WITHOUT INCREASING THE FLOW RATE

摘要

The invention relates to a method for the reliable transmission of a data flow in the form of packets Pi including at least one header Hi (302), said header being compressed (310, 312) via at least a first header compression step, said packets being fragmented into a series of cells (307, 314), said cells (307, 314) having an identical fixed size, said fragmentation resulting in the occurrence of a padding section (311) in the last of said cells (314), said method being characterised in that the space occupied by said padding section (311) is used at least partially for inserting redundancy data, said redundancy data being used for increasing the reliability to transmission errors of said compressed header (310).
