Overview

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


Updates to previous draft

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)


Next steps

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
