Growth of the Mobile Internet
IPv6 in UMTS
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

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 in UMTS
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)
