7 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. Support of IPv4 and IPv6 in the network nodes Ericsson NEA

9 IPv6 in IMS IMS with IPv4 has been deployed and operated in commercial networks in the world. Smooth migration and coexistence of IPv6 and IPv4 is required. We have the tools: Protocol translation mechanisms built in IMS Tunneling Dual stack in IMS Ericsson NEA

10 IPv6 in IMS Goal: Both IPv4/v6 traffic to/from terminals, as well as to/from other networks, shall be supported. IPv4-IPv6 Interworking principles in IMS (e.g., IMS-ALG, IMS AGW, BCF defined in IMS standards) IPv6 & IPv4 clients Fixed Access Network CLF/ A-RACF Edge Router Mobile Access Network E2, Rq Gm A-SBC P-CSCF/ ALG SPDF C-BGF A-SBC ASs P/I/S-CSCF MRF HSS PSTN Interworking N-SBC IBCF/ IMS-ALG TrGW (I-BGF) PSTN IPv6, IPv4 or Dual stack Peering SIP NW PCRF Rx P-CSCF/ IMS-ALG GGSN/ P-GW Gm IMS AGW IMS-Domain Ericsson NEA

11 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 IPv We will work with the Member States to enable IPv6 on public sector websites and egovernment (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. Ericsson NEA

12 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 is used 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 and IPv4 interworking, and to have support on all interfaces for dual stack on all nodes.
