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.

Abstract: A policy routing function (“PRF”) allows requests for emergency services (e.g., 9-1-1 calls, text messages to 9-1-1, etc.) dynamically routed to an emergency responder based on rules and/or user defined geographic overrides in support of Next Generation 9-1-1. Each user provided geographic polygon layer within this data set is represented by one or more polygons, with each polygon containing routing criteria, routing rules, priority, and expiration parameters. This geographic data set may also have a base geographic polygon layer of one or more polygons that define the “normal” or “default” routing conditions. Utilizing a user provided geographic data set the PRF interrogates an emergency caller's location against the polygon(s) and applies the routing rules of the highest level geographic polygon layer polygon that has a true routing condition.
