PSAP Deployment Options

PSAP equipment is IP or NG9-1-1 capable before core NG9-1-1 is installed

PSAP equipment or software upgraded when core NG9-1-1 is installed

Multiple PSAPs deploy a hosted (shared) call handling system

PSAPs use LPGs to interface to core NG9-1-1 system, operating temporarily as `legacy PSAPs’

Any combination of the above13

• Location always provided by the LIS

• Location can be civic address or geographic coordinate

• Location by value or by reference

• Locations for wireline may use existing ALI

• Exceeds today's Location needs

The locations in the LIS are validated against the provisioned GIS data in the Location Validation Function – the LVF

LVF Location Validation Function

• The Location Validation Function (LVF) validates the Location stored in the Location Information Server (LIS)

• LVF uses Local 9-1-1 Authority GIS data for location validation

• Gives Local 9-1-1 Authority total control of their data

Emergency Call Routing FunctionECRF

• Same 9-1-1 Authority GIS Data as used in the Location Validation Function (LVF)

• GIS data uses call location to Route “calls” to correct PSAP• You send it location (in civic or geo form) and it gives you

back a URI of the PSAP to forward the call to

ESRP

• Gets a location, queries ECRF• Uses URI from ECRF to send call to the correct

PSAP Applies a “Policy Routing Function” – Policy

Based Routing Policy can Override PSAP URI provided by

ECRF

Security for an i3 NG9-1-1 ESInet

• Security Credentials allows Interoperability– LIS uses ESRP and PSAP credentials for location dereference– ECRF / LVF accepts client credentials for routing / validation– PSAP operator certificate-based on authorization and

access

• Secure Communication and Privacy– Encryption of Data for Secure Storage and Transport– Protection from External and Internal Threats – Provides a security framework to protect NG9-1-1 systems

Security Objectives Develop a comprehensive Security

Framework for NENA

Develop the minimum appropriate Security Standards for each component or area of the 9-1-1 system

(i.e. PSAP/CPE, Network, Providers, Database, etc) 

Work Cooperatively with other Committees and workgroups and outside agencies as necessary

Existing systems Consider the use of existing information and

standards when available and appropriate.

(i.e. DHS, NIST, ANSI, NLETS, etc.)
