  1. Extensions to the PMIPv6 Access Network Identifier Optiondraft-pazhyannur-netext-civic-location-ani-subopt-02.txtRajesh S. Pazhyannur(presenter)

  2. Overview • RFC 6757 defines ANI option for PMIPv6 Sub-options for Geo-location, Network Identifier, Operator Identifier • Draft extends ANI with following sub-options Civic Location Sub-option MAG Group Identifier Sub-option ANI Update Timer Sub-option

  3. Updates to previous draft • Civic Location format extended Useful for MAG on indoor Wi-Fi APs (no accurate GPS information) Encoding: Binary (DHCP-RFC 4776) or XML (PIDF-LO RFC 5139) Note on Security Consideration (identical to that in RFC 6757) • Update-Timer Sub option When update-timer expires, MAG sends update only if ANI values have changed Useful when MAG is on a Wi-Fi controller. Clients make frequent handover between APs. Mobility between APs visible to MAG but need not be reported to LMAsince inter-AP mobility is not handled by PMIPv6. PBU/PBAs just for ANIupdate may cause overload. • Group Identifier Sub option A collection of MAGs (typically in same area) is assigned a group ID. Useful when MAG is on a Wi-Fi AP. Today, Access Points typically provisioned with an AP group. AP groups are used for common policy (QoS, Access, etc.); coarse AP location; sharing 802.11 keys (PMK)

  4. Next Steps • Civic Location has been adopted by s2a for Release 12. Stage 3 (protocol specification) is ongoing and expected to finish by July • Seeking adoption as a working group document More credible draft Reference for 3GPP documents
