Abstract

Standard methods exist to compress the headers of IPv4 IP/UDP/RTP packets. These methods do not work when these packets are sent using Mobile IP. This article proposes compression and decompression methods for RTP packets that can be used at a Mobile IP Home Agent (HA) and Foreign Agent (FA) that allow for standard compression of the resulting packets on the links between the HA and the FA.
