  2. IPv6 in Mobile Wireless Networking • Dana Blair • dblair@cisco.com • Contributors • Steve Deering, Mark Denny, Dennis Clare, Michael Ramalho, Greg Pelton, Ajay Mishra, Prasanna Satarasinghe, Kittur Nagesh, Jim Christy

  3. Agenda • Current Cellular IP Connectivity • 2.5 and 3G Cellular IP • IPv6 in 3G • Backbone Services for 2.5/3G

  4. Agenda • Current Cellular IP Connectivity

  5. Mobile Wireless Technologies • Cellular • GSM, TDMA, CDMA, W-CDMA • Wireless LAN - 802.11 • Personal Area Networks (PAN) • Bluetooth, 802.15 • Satellite • Public cellular operators have earliest need for IPv6

  6. Wireless/Cellular/Mobile Challenge This trunk is onlyused when call originates in BSCA,2 MSCB BTS BSCB Circuit Switched Cellular Mobile Switching Center(MSCA) Base StationController (BSCA,1) 2G BTS PSTN BTS BSCA,2 Radio Control Functionsare in BSC “Voice Anchor”changes to BSCB Selector Distribution Function (a.k.a., multidiversity function)is in BSC MSC is a specialized Class 5 CO • 3G architectures BACKHAUL IP the same way during a phone call!

  8. Agenda • 2.5G and 3G Cellular

  9. Cellular Standards • 3GPP2 - www.3gpp2.org • Uses Mobile IP • Based in US • Developed TDMA/CDMA/IS-41 standards • Next Generation is 3GPP2 using CDMA-2000 Radio technology

  10. Overview of Mobile IPv4rfc2002 CN • 1. MN discovers Foreign Agent (FA) • 2. MN obtains COA (FA - Care Of Address) • 3. MN registers with FA which relays registration to HA • 4. HA tunnels packets from CN to MN through FA • 5. FA forwards packets from MN to CN or reverse tunnels through HA (rfc3024) 5. 4. FA HA Internet 1. and 2. 3. MN

  11. Cellular Standards • 3GPP - www.3gpp.org • 3GPP defined GTP IP tunneling protocol for mobility. • Based in Europe • Developed GSM/GPRS standard • 70% of mobile phones use GSM • Next Generation is UMTS using Wideband CDMA

  12. GPRS/UMTS Packet Services Local Part of End-to-End Network(s) Gi, v4/v6 SGSN Local IP Network GN Internet MS ATM RAN GGSN Edge Router(s) Inter-PLMN Network Gp Radius DHCP DNS

  13. Agenda • IPv6 in 3G Cellular

  14. Rationale Behind IPv6 • IETF IPv6 (was NG) WG began in early 90 to handle addressing growth issues • IP everywhere—data, voice, audio, video integration • Looking at few numbers... • ~300 million mobile phone users in 1998, 1 billion by 2005 • 1 billion cars in 2010 with GPS and Yellow Page services • Worldwide deployment of Internet appliances • Emerging populations/geopolitical • China, India, Japan, Russia,… • Internet in every school,…

  15. 3G Cellular requires IPV6 • - Next Generation GSM standards require IPv6 for Packet Services including VoIP. • - Next Generation Mobile Devices shall exclusively support IPv6 for the connection to packet services including VoIP. • www.3gpp.org - 3G TR 23.821

  16. Blue - v4/v6 Red - v4 Green -v6 Packet/VoIP 3GPP Architectural Details MRF/MP Unified Messaging (Uone) Feature Servers SGW SS7 GW SS7 SS7 CCSC Sun Netra (OptiCall) Announcement Server (AS5400) MGW PSTN-GW (AS5850) PSTN IM Subsystem IPv6 Network Local Part of End-to-End Network(s) Gi, v4/v6 SGSN v4/v6 Local IP Network Gn, v4/v6 MS v4/v6 IP RAN GGSN v4/v6 Edge Router(s) v4/v6 IPv4 Network Inter-PLMN Network Gp, v4/v6 Radius DHCP DNS Services v4/v6

  17. Overview of Mobile IPv6draft-ietf-mobileip-ipv6-13.txt CN • 1. MN obtains IP address using stateless or stateful autoconfiguration • 2. MN registers with HA • 3. HA tunnels packets from CN to MN • 4. MN sends packets directly to CN or via tunnel to HA • Binding Update from MN to CN removes HA from path. 4. 3. HA Internet 1. 2. MN

  18. Agenda • Backbone Services 2.5/3G

  19. BackBone Services • IPv4 transport • IPv6 transported in IPv4 or MPLS • NAT-PT for IPv6 <-> IPv4 • Home Agent Services • Virtual Private Networking

  20. BackBone Services • QoS Services • DiffServ, Traffic Engineering, … • draft-ietf-mpls-diff-ext-07.txt • draft-ietf-mpls-rsvp-lsp-tunnel-07.txt
