Almost unlimited number of addresses Built in security support (IPsec) Built in mobility support (MIPv6) Efficient routing Features for simplified Network management Same level of QoS support as in IPv4 with potential improvement Benefits of IPv6
User level addressing in a 3GPP Network • Possible scenarios • Stateless Address Autoconfiguration* • Stateful Adress Autoconfiguration (DHCP client in the UE) • Stateful Address autoconfiguration (DHCP client in the GGSN) • Static Addresses in the HLR

IPv6 over the air • ROHC approved by 3GPP • For optimal Header Compression, changes in headers within one connection should be minimised. • Limit the use of IPsec for IP signalling and other mandatory scenarios. • Enable partial UDP checksum for real time applications (UDP Lite)
