Abstract
The invention is a method of relocating of header compression/decompression functions between a plurality of network entities and mobile compressors and/or mobile decompressors. A method of communication in a packet network which transmits packets having compressed headers in accordance with the invention includes establishing a connection between a first network node and a second network node including storing context information used with compression and decompression of the headers of the packets at the first and second nodes; and changing the connection between the first network node and the second network node to a connection between the second network node and a third network node including transferring the context information representative of the context information stored by the first node to the third network node which is stored by the third node as the context information of the third node and using the stored context information at the second and third nodes for compression and decompression of the headers of the packets at the second and third nodes.
