"Access Network Identifier (ANI) Option for Proxy Mobile IPv6" [RFC6757] introduced the ANI mobility option. This enabled a Mobile Access Gateway (MAG) to provide the Network-Identifier, Geo-Location, and Operator-Identifier sub-options. When the access network is WLAN, the Network-Identifier sub-option may contain the Service Set Identifier (SSID) and the Basic Service Set Identifier (BSSID) of the Access Point (AP) and the geolocation of the AP, and the Operator- Identifier may contain the realm of the operator managing the WLAN. The MAG sends the above information to the Local Mobility Anchor (LMA). The LMA may use this information to determine access-network- specific policies (in terms of Quality of Service (QoS), Deep Packet Inspection (DPI), etc.). Further, the LMA may make this information available to location-based applications.

  Extensions to the Proxy Mobile IPv6 (PMIPv6) Access Network Identifier                                  Option


   The Access Network Identifier (ANI) mobility option was introduced in    RFC 6757, "Access Network Identifier (ANI) Option for Proxy Mobile    IPv6".  This enables a Mobile Access Gateway (MAG) to convey    identifiers like the network identifier, geolocation, and operator    identifier.  This specification extends the Access Network Identifier    mobility option with sub-options to carry the civic location and the    MAG group identifier.  This specification also defines an ANI Update-    Timer sub-option that determines when and how often the ANI option    will be updated.
