  1. IPv6 in 3GPP Evolved Packet System IETF#80 V6OPS WG, 31-March-2011 draft-korhonen-v6ops-3gpp-eps-06 J. Korhonen, J. Soininen, B. Patil, T. Savolainen, G. Bajko, K. Iisakkila IETF80 - Prague

  2. Outline • History & Timeline • Updates since IETF#79 • Operational aspects of IPv6-only • IPv6 Address configuration clarifications • IPv6 Roaming considerations • Inter-RAT handovers and fallback scenarios • Next Steps IETF80 - Prague

  3. History & Timeline • First presented in IETF-3GPP workshop in SFO just before IETF#74; to document how IPv6 fits into 3GPP EPC.. • Presentations in IETF#77 and #79. • Since then (-00) the draft has evolved to cover important parts of IPv6 from pre-Rel-8 (GPRS), Rel-8, Rel-9 and some Rel-10. IETF80 - Prague

  4. Updates since IETF#79 • Made the draft “opinion neutral” • Only documents what is specified by 3GPP. • Operational aspects of IPv6-only networks • Basic gotchas documented from 3GPP PoV. • Removed some pros associated with dual-stack approach. • IPv6 Address configuration clarifications • About /64 uniqueness, • GGSN/PGW generated IID, and • Handling of PIOs. IETF80 - Prague

  5. Updates since IETF#79 cont’d • IPv6 Roaming considerations: • There is motivation to restrict IPv6 roaming when it does not officially exist or the service quality cannot be guaranteed.. • Discuss ways to enable / prohibit roaming in case by case granularity.. currently no standardized method available. • Inter-RAT handovers and fallback scenarios: • There are IPv4, IPv6 and IPv4v6 PDN Types to select from. • There are IPv4, IPv6, IPv4v6 and IPv4_or_IPv6 in provisioning • Which type to select depends on settings in UE, MME, HSS/HLR and GGSN/PGW.. not to forget legacy SGSNs that may modify requested types in between. • UE may receive an indication whether opening two bearers to mimic IPv4v6 is ok or not if requesting IPv4v6 fails etc. IETF80 - Prague

  6. Possible additional content considerations.. • The draft is~ready content/topic wise, however: • One could add some text related to RFC3316 recommendations, although the RFC is not about EPC. • Also a reference to RFC3314,although the RFC is not about EPC. IETF80 - Prague

  7. Question to v6ops WG • Adopt this I-D as v6ops WG doc? • Can proceed to WGLC immediately since content is fairly complete IETF80 - Prague
