Geopriv Location Object Registries 2004-11-03 2022-09-15 First Come First Served These tokens are associated with the PIDF-LO object. A-GNSS Assisted Global Navigation Satellite Systems A-GPS GPS with assistance AOA Angle of Arrival best-guess The LIS cannot provide an accurate location. The value is its best guess, but may be very inaccurate. Cell Location of the cellular radio antenna DBH Device-Based Hybrid DBH2 A Device-Based Hybrid system (typically on a mobile device) produces a compound location that includes a full or partial Civic Address in addition to the Geodetic Location normally expected from a DBH system. Distinct from RevGeo because, even if the DBH system uses reverse-geocoding to determine the Civic Location, the DBH system determines and delivers the Civic Location, not a downstream entity. NENA-REQ-003.1-2022 DBH_HELO Device-Based Hybrid using Apple Hybridized Emergency Location Derived This value is intended to represent a location object determined by geocoding or reverse geocoding a location determined by some other method. Derived-RevGeo A full or partial Civic Location, which is not validated against an LVF, is derived by reversegeocoding a Geodetic Location. The original Geodetic Location MUST also be delivered with the derived Civic Location. Used when a downstream entity other than the calling device reverse-geocodes a Geodetic Location it received from an upstream entity, such as location services/DBH. NENA-REQ-003.1-2022 DerivedRevGeo-LVF A full or partial Civic Location, which is validated against an LVF, is derived by reverse-geocoding a Geodetic Location.

Manual Entered manually by an operator or user, e.g., based on subscriber billing or service location information Manual-FIXED A Civic Location is derived by knowledge that the calling device is connecting via a semi-static small-cell device that is at a known, validated, address, such as a pico/femtocell or that the calling device is a fixed cellular device. NENA-REQ-003.1-2022 Manual-RESD A Civic Location is provided using knowledge that the calling device is a static device at a known, validated, residential address.
