Abstract
A method to automatically alter the ECRF route determination for call delivery to a PSAP, and better identify the appropriate responders for incidents where significant elevation or height of the caller's location is involved. A pre-provisioned database for elevation and height consideration is provided either as part of or integrated with the ECRF based on the use of this additional sub-addressing data (building, height, etc.), and cross referenced to a pre-provisioned elevation or height associated with each specific building or floor. The routing of requests for emergency services through the use of either service provider delivered geodetic or civic location is provided. Emergency services routing and responder determination is based on both sub-addressing information in combination with a cross reference database of vertical height identifiers by accessing a pre-populated database of this cross-reference information.
