Abstract:
1. A packet handling method for a telecommunications system, the method comprising: extracting quality of service information from a received packet, the extracted quality of service information having been supplied by a network layer or higher layer of the telecommunications system; processing the received packet, at a compressing node, using a process having a process-associated quality of service requirement to form a processed packet, wherein the process-associated quality of service requirement defines a quality of service required by the process, the process comprising the process-associated quality of service requirement comprising at least one of the following: header compression; payload compression; signaling compression; encryption; authentication; checksumming for verification; and sequencing; deriving header-included quality of service information using both the quality of service information extracted from the received packet and information indicative of the process-associated quality of service requirement; including, in a channel part of a compressed header for the processed packet, the header-included quality of service information, wherein the channel part of the compressed header is accessible by intermediate nodes on a channel between the compressing node and a decompressing node; and transmitting the processed packet over the channel, wherein the processed packet is at a same layer as the received packet.
