Benefits of IPv 6 • • • Almost unlimited number of addresses Built in security support (IPsec) Built in mobility support (MIPv 6) Efficient routing Features for simplified Network management Same level of Qo. S support as in IPv 4 with potential improvement IPv 6 in UMTS

Addressing of a 3 GPP Network IPv 6 in UMTS

User level addressing in a 3 GPP 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 IPv 6 in UMTS

IPv 6 over the air • ROHC approved by 3 GPP • 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) IPv 6 in UMTS
