Abstract
The use of bandwidth constrained wireless links in mobile networks necessitates the use of bandwidth saving header compression schemes. A scheme is proposed that provides an architecture for using network layer and transport layer compression efficiently based on the network. The scheme provides a distinct compression algorithm for network layer and for transport layer in headers such as the IP/TCP or IP/UDP headers. The scheme furthermore provides a layer 3 signaling for multi-link compression.
