13 Why IPv6 for Cellular Network? Tens of millions of Active Mobile Stations A remedy is to change IP addresses frequently. A remedy is header compression technology. IPv6 is a solution because it provides abundant IP address resources. whose benefits are: Simplifying network configuration Capable of providing multiple IP addresses for a device Capable of Providing real IP Push services whose concerns are: Attacks on global IPv6 addresses Larger IP Header for real time data than IPv4 APRICOT 2005 IPv6 Technical session, 24 Feb, 2005, F.
