4. 4 © 2015 Airbus DS Communications, Inc. All rights reserved. E911 LOCATION VALIDATION All Telephone Service Providers/Local Exchange Carrier (LEC) are required to input their subscribers telephone numbers (TN) and service addresses into the 911 database system. All entries are required to be MSAG valid. This database is then referenced by local PSAP’s to retrieve Automatic Location Information (ALI). LEC 911 Database (tabular) PSAP MSAG (tabular) ANI ALI TN & Address Invalid Address Range TN & Address E9-1-1 Databases used for routing are tabular.

All rights reserved.  GIS data for Location Validation  GIS data for Emergency Call Routing – Geospatial Call Routing GIS data also used for:  Discovery of ‘Additional Location Data’- fx ECRF ‘Additional Location Data’ is associated with a specific location, it does not refine location information, it provides additional information about a particular site, i.e. site plans, MaterialSafetyDatatSheets – think preplans  Map Display – display emergency caller’s location on a map  Vehicle Routing GIS will be used behind the scenes as the database for location validation and geospatial call routing. These decisions will be made with no calltaker interaction. HOW CALLS WILL BE VALIDATED AND ROUTED IN NG9-1-1 – GIS DATA

ACT II – LOCATION VALIDATION 12 Location Information Server (LIS) Location Validation Function (LVF) Spatial Interface (SI) 9-1-1 Authority GIS Data Is this a valid location in GIS? YES or NO LIS – Location Information Server Customer databases interact with the LIS LIS queries the LVF Civic addresses are validated prior to being stored in the LIS by the LVF – validated against the GIS Generates a PIDF-LO (Presence Information Data Format – Location Object) – can be a civic address or a geo-coordinate LVF – Location Validation Function Pre-validation, validates before loading to the LIS database Similar to MSAG, verifies that the civic location matches a known address in the 9-1-1 Authorities service area Able to validate an address, not just address range Receives as input: PIDF-LO and service URN – returns – location validation Queried by LOST protocol Origination Network Location Validation references a GIS database.

Route to PSAP A ESRP – Emergency Services Routing Proxy Call routing engine Closest thing to a selective router in NG9-1-1 Uses the ECRF(GIS) to choose how to route a 9-1-1 call Receives as input: PIDF-LO and service URN After consulting ECRF and the PRF, routes call to PSAP ECRF – Emergency Call Routing Function Provides GIS based Next Generation call routing Replaces legacy selective router databases Allows for alternate dynamic call routing Receives as input: PIDF-LO and service URN– returns –route URI Queried by LoST protocol PRF Geospatial routing is based on results of a spatial query from a GIS database.
