Proposed behavior for robust header compression over a radio link

International audienceThe use of IPv6 in the third generation of cellular networks leads to weak performance of the network systems because the IPv6 header size sent in each packet represents more than twice the payload normally used in video or audio applications. The IETF ROHC (robust header compression) working group has defined a new header compression mechanism to reduce the transmission time and increment the use of the bandwidth in networks with scarce resources. The present version of ROHC considers a static configuration of the ROHC implementation parameters and at the same time does not negotiate some of the link parameters. This paper proposes a dynamic configuration for UMTS radio networks through negotiation. Dynamic configuration enables ROHC to improve its efficiency and robustness based on radio link parameters
