HEADER COMPRESSION BETWEEN A COMPRESSOR AND A DECOMPRESSOR

摘要

The invention relates to a method for header compression between a compressor (10) and a decompressor (20). The method comprises providing a set of configuration parameters to be negotiated between the compressor (10) and the decompressor (20), wherein said set comprises a specific parameter whose value indicates whether reordering and/or packet loss is tolerated between the compressor (10) and the decompressor (20). The method further comprises indicating in a full header whether subsequent compressed headers will contain small packet sequence numbers (pkt_nr). These small packet sequence numbers (pkt_nr) are used in order to detect a reordering of packets and/or packet loss between the compressor (10) and the decompressor (20).
