IPv6 in 3G

Common architecture 2003
-Ericsson 3G Networks based on the same
Server/Gateway architecture for wireline for
wireless -IPv6 supported in 3GPP R5 , with
implementations now and available in
infrastructure and terminals from 2003 -Ericsson
Multimedia strategy in line with 3GPP and IPv6
Media Gateway

And ....by end 2003 access will be

• 1 B fixed IP nodes (ISP access etc)
• 1 B mobile nodes
• 1 B circuit switched and high bandwidth nodes
• and combinations thereof for various convergence
  services
• plus x Million Bluetooth machine-machine
  communications
• plus x Million xDSL etc nodes with ngt10 logical
  users per node
• plus x Billion Mobile Internet sessions calling
  on services
• plus many Million Internet hosts (2001 120 M,
  IPv4 limit approx 200 M)
• thus putting in focus the need to solve IP
  address crunch in some regions of the world, and
  add new capabilities in this connection

Basic technical IPv6 evolution (with mandated
interoperability with IPv4 services)

• 128 bit addresses in terminals for global
  reachability and scalability
• Acceptance,user friendliness and support IPv6
  self configuration nodesIPv6 self configuring
  nodes
• Simplified header for routing efficiency and
  performance
• Deeper hierarchy and policies for network
  architecture flexibility
• Security with mandatory seemless IPSEC support of
  all IPv6 devices
• Bandwidth and mobility header compression ,
  soft hand over,and MobileIP for computing devices
• Interoperability fixed/mobile
• Enhanced multi-cast support with increased
  addresses and efficient flow control

Multiple levels of mobility in Mobile networks ,
and relation with IP protocols

• Access level
• classical cellular,and Mobile-IP
• Network level
• Soft handover,and Mobile-IP (selectively)
• Roaming level
• - Handled in network
• Application level
• H.323 mobility, POP3,WAP 2 Gateways,etc

KEY ISSUES TODAY AROUND the USE of IPv6 In
COMMERCIAL COMMUNICATIONS NETWORKS

• Identifying incremental service revenue sources
  for operators derived from using IPv6,sometimes
  alongsid IPv4, and match them against costs
• Identifying new service revenue sources for
  operators derived from using IPv6
• Migration plans for infrastructure and
  integration services,including OSS and Network
  management
• DECISION PROCESS MUST BE IN ORDER ABOVE

14
IPv6 opens up for changes in Business models
favorable to operators and users

• - Business /traffic/infrastructure/service
  business models for IPv6/IPv4 mobile traffic and
  services (Ericsson Hungary)
• - Business concepts and technical DNS
  solutions allowing for efficient management by
  operators of IPv6 addresses in relation to
  subscriber profiles
• - Billing solutions with bundled IP/ non-IP
  IPDR and CDR tracking (Ericsson EHPT)
• - Collaborations with operators and new users

15
USE In HIGH SPEED INTERNET ACCESS SERVICES

• Technical dominant IPv6 features
• -increased IPv6 address space
• -IPSECv6 with both data encryption and user
  authentification
• Incremental revenue
• -price multiple addresses and flows managed at
  same cost (e.g Japanese 180 Mbit/s ISPs)
• New revenue
• -price enhanced security features

16
USE in STORAGE AREA NETWORKING

• Technical dominant IPv6 features
• -IPv6 address hierarchy
• Incremental revenue
• -more reliable management of large data stores
• New revenue
• - content provisioning into 3G enabled mobile
  services without NAT handling

17
USE in ENTERPRISE VPNs and ASPs

• Technical dominant IPv6 features
• -existence of IPv6 flow label field
• -MobileIPv6 integration
• -IPSECv6 integration
• -IPv6 address space breaking 4096 VLAN address
  limitation
• -combination with 802.1p/q/r/s QoS and extended
  addressing features
• Incremental revenue
• -transparent LAN services with reduced
  configuration costs
• -reduced need to map VLAN IDs at
  network-to-network transition points
• New revenue
• - enterprise specific tarifing characteristics
  encapsulated into flow label field
• -services from supplying enterprises with AAA
  servers for their VPNs
• -premium service revenue from mobile workers
  which take their virtual office with them with
  full security
• -M-Business services which can only be deployed
  with IPv6 features from risk points of view

  labels and tags are linked to IPv6 addresses in
  applications

18
USE in MOBILE TERMINALS and CONSUMER DEVICES

• Technical dominant IPv6 features

  stronger auto-configuration at installation time
  (compare e.g. WAP 1.0 terminal configuration via
  SMS with Mobile Internet service configuration
  with IPv6)

  control

B.t.w some Ericsson implementations/initiatives
using IPv6

• AXI 820 mobile real time IPv4/IPv6 wireless
  router announced _at_ GSM Cannes (Ericsson Radio)
  and fully operational
• IPv4 and IPv6 enables Media Gateways (MGW) on a
  low cost high performance and highly available
  platform (Cello)
• One comprehensive server routing IPv4/IPv6 stack
  with large protocol suite incl OSPF v6
• MobileIPv6 protocol by Ericsson Research
• IPv6 in Ericsson Juniper router products (joint
  venture)
• Key role in 6INIT , 6WINIT, NGI project in Europe
  and others

  platforms for terminals and PDA creation
• Life IPv6 VOIP trials such as Smart Tone (HK)
• Interoperable IPv4/IPv6 applications for military
  needs (NATO, IPANEMA , Swedish NetDefence)

22
And some other initiatives at Ericsson where IP
is in focus ...

• Joint venture with Volvo on Internet car (already
  demonstrated)
• IP in Bluetooth components and systems (Ericsson
  Microelectronics, Ericsson Technology licensing
  company for Bluetooth technology)
• IP in building management (JV with Skånska and
  others)
• and more to come...

23
EVOLUTION

• For mobile and convergence networks , no doubt
  about
• -the need for v6
• -v6 advantages
• -v6/v4 coexistence and migration need
• but
• -lack of importance in IETF and some regions of
  the world as to a realistic migration driven by
  cost of ownership and competitive advantages at
  service level
• -the absolute need for quality implementations
• -reduce fears as to migration , retraining ,
  legacy , etc...

24
IPv6, conclusion

• Technology maturing
• Inevitable in mobile networks, co-existence in
  others
• Good Business models with IPv6
• - Business /traffic/infrastructure/service
  business models for IPv6 mobile traffic and
  services
• - Billing solutions
• - Collaborations with operators and new users
