Signaling compression/decompression

摘要

The present invention relates to a method of compressing or decompressing a signaling message in a packet data network, wherein a parameter information is provided in a header portion of a protocol message of the packet data network. The parameter information specifies at least one processing detail of a compression or decompression mechanism and is forwarded together with the protocol message through the packet data network to a compression or decompression function of the packet data network. The compression or decompression mechanism at the compression or decompression function is then set in accordance with the parameter information. Thereby, a better compression of the first or first few messages can be achieved, as the parameter information is directly available.
