  1. 3GPP CSIPTO Alper Yegin Samsung Electronics IETF 90

  2. SIPTO • Selected IP Traffic Offload • R10 feature allows PGW change to streamline PDN (Packet Data Network) connections. • SIPTO@LN (Local Network) moves GW towards the edge, it can even be co-located with base station Flat IP

  3. CSIPTO • Issue: Service disruption • Solution : Network and UE coordinating GW changes • CSIPTO: Coordinated SIPTO, a R13 SA1 Work Item

  4. Use Case 1 • After handover, optimal PDN connection (conn#2) setup for flows that do not require IP address preservation • Suboptimal PDN connection (conn#1) maintained until flows that require IP address preservation terminate

  5. Use Case 1 • Allows L4+ mobility protocols (e.g., MPTCP, SIP) to perform soft handover

  6. Use Case 2 • 2 PDN connections are setup, one with IP address preservation, one without. • Each flow bound to a connection according to its IP address preservation need. @ core network

  7. Use Case 3 • By default, PDN connection with LGW is setup. (conn#1) • Additional PDN connection with PGW (conn#2) setup and used only for flows that need IP address preservation  On demand • PDN connection with PGW removed after flows using it terminate. @ core network

  8. Status • SA1 (Services) study phase completed • Use cases and requirements: • http://www.3gpp.org/DynaReport/22828.htm • SA1 normative phase initiated (May 2014) • Work item description: • http://www.3gpp.org/ftp/tsg_sa/TSG_SA/TSGS_64/Docs/SP-140235.zip • Target completion: Aug 2014 • Next: SA2 (Architecture)
