Abstract
The present invention involves a method for IP header compression for Real-Time Transport Protocol (RTP) packets that includes header compression for the outer IP layer that carries IPsec ESP tunnel traffic. The preferred embodiment of the invention involves a method of producing minimal VoIP packet size in a GAN user plane by defining an ESP/UDP/IP profile for ROHC; using the ESP/UDP/IP profile to compress the outer layers carrying IPsec ESP tunnel traffic in the GAN user plane; and using a ROHC RTP/UDP/IP profile between IPsec ESP tunnel endpoints for additional compression.
