  2. What is the problem • RFC 6757 defines ANI option for PMIPv6. • Includes sub-option for Network Identifier: e.g., BSSID, SSID Geo-Location Identifier: Lat/Long Operator Identifier: e.g., MCC/MNC • In many Wi-Fi deployments, especially indoors, challenging to get Geo-Location • However, Civic Location is a valid option • Proposal. New Sub-option for Civic Location (RFC 5139--- PIDF)

  3. ANI Update-Frequency Option • How are PMIPv6 be used in Wi-Fi deployments PMIPv6 MAG on WLAN controllers (WLC) PMIPv6 MAG on Wi-Fi APs • ANI update behavior differs based on deployment ANI provided at initial session establishment However, when MAG on WLC client mobility between APsmay not reported to LMA. As a result, ANI information like (BSSID, Geo-location) may be stale However, when MAG on AP, client mobility between AP is reported to LMA. So ANI information is always current. • Proposal ANI Update-Frequency option: MAG can provide hint to LMA about how often it updates. MAG on AP may use a TTL of FFFFFFFF. MAG on WLC may use a TTL depending on how often it sends PBUs.

  4. Next Steps • Feedback Bad idea/Indifferent/Good idea • Considered for adoption as a working group document
