China: Million
Europe: 80 Million
US gov. 168 Million
1980: 200 user on 1 mainframe

5. Benefits of IPv6 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

6. Addressing of a 3GPP Network

7. 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

11. 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)
