    • Mobile Terminals as a Driver for IPv6 Deployment John Loughney john.loughney@nokia.com1 © NOKIA FILENAMs.PPT/ DATE / NN
    • Initial Assumptions • IPv6 enabled networks are needed, but are not sufficient. Applications& uses will drive the deployment of IPv6. • Human communication has been end-to-end. • Mobile terminals have become an extension for person-to- person communication. • Not enough IPv4 addresses for all devices. • NAT breaks end-to-end communication.2 © NOKIA FILENAMs.PPT/ DATE / NN
    • Future Requirements Drive IPv6 • Converged networks (Wireless, home networks, multimedia). • Address space (IPv4 is running out of space, IPv6 offers 2128 addresses instead of 232). • Mobility is an embedded part in IPv6, which enables the scalability to global mobility. • IPv6 has new features optimized better to mobile world (Address autoconfiguration, route optimization, in built mobility, always on).3 © NOKIA FILENAMs.PPT/ DATE / NN
    • Benefits of IPv6 • 128-bit address space. IP addresses can be permanently assigned to end devices whatever they are • NAT (network address translation) not needed anymore, end to end functionality can be guaranteed • Faster routing due to smaller routing tables • New push services, always on services (reachability and connectivity) • Embedded mobility and roaming support (Mobile IPv6) • Operational benefits (e.g easier management with autoconfiguration, plug and play) • Security integrated to IPv6 (IPSec)4 © NOKIA FILENAMs.PPT/ DATE / NN
    • IPv6 vs. IPv4 Feature IPv4 IPv6 In theory 4 billion, Large enough, 2128 Address space in practice much less Can serve a restricted Embedded, scales to Mobility number of terminals global mobility Several alternatives Included in IPv6 to be Security and scaling problems deployed global VPNs No comprehensive standard solution Integral part of IPv6 Autoconfiguration standard (DHCP exists)5 © NOKIA FILENAMs.PPT/ DATE / NN
    • Mobile Devices Need IPv6! • A huge number of IP addresses are needed for future mobile terminals - IPv6 is the way to do it. • IPv6 eliminates the use of private IPv4 address spaces and NATs. Future IP applications benefit from global IPv6 addresses. • Transition from IPv4 to IPv6 will be a gradual evolution. From a mobile network point of view the principal transition mechanisms are dual stacks and tunneling. • Nokia mobile terminals shall start supporting IPv6 (dual stack) in the near future. Symbian Operating System v7.0 including IPv6 (dual stack) support has been released.6 © NOKIA FILENAMs.PPT/ DATE / NN
    • New Applications and Services • Messaging applications are important - text messages (or SMS) is a good starting point. • Multimedia messaging (MMS) is about to begin. Mobile terminals with integrated digital cameras are being introduced. • More applications with demanding bandwidth needs. The cellular data networks will have an important role supporting all these services. • Mobile devices will have large color displays. • Instant Messaging, Presence, Java applications, browsing, peer- to-peer applications … • Streaming with one or several media components, like audio, video … • 3GPP Release 5 IMS (IP Multimedia Subsystem) networks will be supporting a wide variety of multimedia services.7 © NOKIA FILENAMs.PPT/ DATE / NN
    • New Services • Basic Voice • Conference calls • SMS (short message service) -> MMS (multimedia messaging service) • Forecast: 100 billion SMS messages / month by the end of 2002 • Store and forward messaging • Rich Calls • Voice plus picture • Voice plus data • Video calls • Content sharing (Napster, etc.) • Location-based Services8 © NOKIA FILENAMs.PPT/ DATE / NN

    • IPv6 Role in 3G Networks • The number Internet connected Mobile Terminals is expected to grow rapidly and exceed the number of fixed Internet connected devices in 2003. • Many GSM/3G operators have an access to only a limited resource of IPv4 addresses • 3GPP has built in IPv6 as part of the 3G standard (e.g. IP Multimedia Subsystem, IPv6 user plane option in GPRS) • The major benefit is the possibility to offer IP based services to unlimited number of IPv6 based devices, mobile or fixed. IPv6 is essential for 3G deployment15 © NOKIA FILENAMs.PPT/ DATE / NN

    • ‘Cellular host IPv6 draft in IETF • Starting point: a clearly defined IPv6 feature set was needed for a cellular terminal. • IPv6 covers many aspects, numerous IETF specifications and is also partly still evolving. • A rapid adoption of IPv6 is desired for cellular terminals. • Cellular terminal software often cannot be upgraded, yet it must meet tough demands for interoperability. • The draft defines three functionality groups: • Basic IP includes essential basic parts of IPv6. • IP Security contains IP Security details. • Mobility contains IP Mobility details. • NOKIA is actively participating this work20 © NOKIA FILENAMs.PPT/ DATE / NN

    • Transition Methods • The main transition mechanisms are • dual IPv4 / IPv6 stacks in network elements and mobile terminals • tunneling (automatic and configured) • IPv4 - IPv6 protocol translators in the network • The principal transition mechanisms are dual stacks and tunneling; translators (such as NAT-PT) are needed if the communicating elements do not share the same version of IP. • The most important elements needing dual stacks in the mobile network are GGSN elements, mobile terminals, edge routers and DNS servers. • IPv6 support is also needed in application servers and proxies, such as WAP gateways, web proxies and E-mail servers. • The majority of the transition mechanisms is provided by the network in order to keep the mobile terminal functionality as light as possible.24 © NOKIA FILENAMs.PPT/ DATE / NN
    • Mobile IPv6 • Mobile IP is already possible with IPv4, however, Mobile IPv6 offers several benefits: • Mobility has been an integral part of IPv6 from the start • No Foreign Agent is needed, improves routing, also if standards change, all Foreign Agents must be modified • Address space limitations of IPv4 will make any usage of Mobile IPv4 in 3G networks extremely difficult • Route Optimization is built in (Mobile) IPv6, but an add on in Mobile IPv4 • IPv4 has problems that will force the deployment of IPv6 especially in mobile networks • MIPv4 – MIPv6 interworking and co-operation isn’t properly standardized25 © NOKIA FILENAMs.PPT/ DATE / NN
    • Mobile IP and GPRS - Overview • GGSN is the link between 3G and Internet, takes care of mobility issues • Node B, RNC & SGSN may change during a PDP context, but GGSN always stays the same. The whole GPRS network looks like a large LAN / Layer 2 network. ⇒ There is no need for Mobile IP in a pure GPRS based packet access.

    • Summary • Messaging & end-to-end services are the “killer application” (SMS, MMS, Instant Messaging, E-mail, Presence) requiring billions of IP addresses worldwide. • There are several methods for transitioning to IPv6, tunneling and dual stack the main ones. • The use of CIDR, DHCP and NAT has delayed the transition to IPv6. • Vendors are announcing software based IPv6 in routers, with limited performance, the next step will be IPv6 in hardware. • Mobile IPv6 for access independency. • From circuit switched voice towards packet switched data. • Messaging is important - SMS, MMS, Instant Messaging, Presence, E-mail • IPv6 will have an important role in the near future mobile terminals. • Mobile terminals become multi-application devices, but optimized for one use motivation.33 © NOKIA FILENAMs.PPT/ DATE / NN
    • Nokia IPv6 Message • Why IPv6 - Practically infinite address space and improved support for IP mobility provides a generic platform for implementing the mobile Internet paradigm. IPv6, perceived as the way to go towards next generation Internet, is a major differentiating instrument for Nokia. • Transition to IPv6 - To help operators, Nokia promotes and supports a number of transition mechanisms for a smooth transition to IPv6 during the transition period. • IPv6 in Nokia Solutions - Nokia as one of the very first drivers of IPv6 is determined to be the front runner also in IPv6 commercial offering: IPv6 enabled terminals, 2G GPRS, 3G, and All-IP system solutions during 2002-2004. • Enhanced Mobility - Mobile IPv6 is seen as an enabler for implementing an enhanced notion of IP and cellular mobility. A promising use case for Mobile IPv6 is to create service mobility whilst on the move within a multi-access environment. A Mobile IPv6 based roaming solution between WLAN and GPRS access technologies is seen as the first step in this direction. • Standardization - Nokia is committed to drive IPv6 to standardization bodies (IETF, 3GPP) and is active in many related34 © NOKIA international Forums (IPv6 Forum).
