  • Patent number: 8331363
    Abstract: A first communication terminal attaches information to be used to recognize whether or not header decompression processing is required and to recognize a forwarding route to a second communication terminal, to compressed data obtained through compressing a header of original data destined for the second communication terminal, and sends the compressed data to the network. Upon receipt of the compressed data, a data forwarding unit in a network recognizes, based on the information, whether or not the compressed data requires the header decompression processing and the forwarding route, and sends, if the compressed data does not require the header decompression process, the compressed data to the recognized forwarding route without decompressing the header.
