Growth of the Mobile Internet
IPv4 addresses: 4B theoretical
China:
9 Million
Europe: 80 Million
US gov. 168 Million
1980: 200 user on 1 mainframe
2000: 1 mobile + 1 PC per user
2020: 200 Embedded, wireless

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

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)
