IPv6 in Mobile Packet Standards- 3GPP Release 8
 Dual stack IPv4v6 for mobile terminals is supported– UE may request IPv4, IPv6 or IPv4v6– Static IPv4 and IPv6 (defined in subscription)– Dynamic IPv4 address- Via PDP context/default EPS bearer procedure- DHCPv4– Dynamic IPv6 address- Stateless address allocation: P-GW assigns a /64 prefix- Stateless DHCPv6 is used for configuring other parameters– Notes:- Operators preferences dictate the use of a single IP version
type only- Subscription may be limited to IPv4 only or IPv6 only
- Single addressing per bearer may be utilized for interworking
with nodes of earlier releases.

IPv6 in IMS
 IMS with IPv4 has been deployed and operated incommercial networks in the world.
 Smooth migration and coexistence of IPv6 and IPv4 isrequired. We have the tools:– Protocol translation mechanisms built in IMS– Tunneling– Dual stack in IMS© Ericsson NEA 2009

Goal: Both IPv4/v6 traffic to/from terminals, as well as to/from othernetworks, shall be supported.

EU Commission IPv6 Action Plan- Issued in May 2008
Action plan targets:Europe should sets itself a target: at least 25% of users should be able to connect
to IPv6 2010.



We will work with the Member States to enable IPv6 on public sector websites andeGovernment (through i2010 eGovernment Action Plan and IDABC Programme).

Cooperate with content and service providers – encourage ISP to provide IPv6
connectivity by 2010, stimulate co-operation thematic network CIP.

Support standardization actions on improvement of interoperability of networks,and protocols running over IPv6 networks.

IPv6 to be used by Research Projects under FP 7 whenever possible

Encourage Member States to use Public Procurement



Undertake targeted awareness campaigns intended for different users groups.



Encourage ISPs to provide full IPv6 connectivity to their customers by 2010

Support of the inclusion of IPv6 on education curricula through a separate study.

Security and privacy issues

Progress Review 2010 to assess the progress through separate study.

Summary Dual stack is part of 3GPP mobile packet core standards(Rel-8 GPRS, EPS).
– For end-user traffic– For the interfaces between network nodes

 IPv4/IPv6 interworking through IP protocol translation isused in IMS standards.
 We have the tools for the most important cases.
– IETF is addressing some remaining deployment scenarios(draft-arkko-townsley-coexistence-00.txt)

 It is important to have full support for IPv6 rollout andIPv4 interworking, and to have support on all interfaces
for dual stack on all nodes.
