  3. 3GPP UMTS Standard Network

  4. 150 Million new users by 2003-2004 implies 500.000/day Mobile Internet 8 year (1992-2000) GSM 4 year 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 devices per user @ 2B humans is 400B 1,000 Fixed 800 Internet 600 In 1999: 100 M PC’s 275 Mobiles (Millions) Mobile 400 200 0 1996 1998 2000 2002 2004

  5. 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

  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

  8. IPv6 domain IPv4 domain End to end incompatibility vs connectivity layer incompatibility End to end V6 UE V4 host Edge router Translator V4 edge router / GGSN V4 backbone

  9. RNC RNS RBS RBS RBS RBS RBS RBS Translation Service Network IPv4 Domain IPv6 Domain Translator SGSN SGSN GGSN Core Network GERAN UTRAN

  10. IPv6 domain IPv6 domain 6 to 4 relay router 001 TLA NLA SLA Interface ID RES 6 to 4 edge router V6 edge router Site Topology Public Topology Interface Identifier V4 backbone 6-to-4 tunnelling 3 8 24 16 64 bits 13 V4_Addr

  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)
