Initial Deployment: Transitional LNGsLater: Direct IP interfaces

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

NENA Copyright 2014
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

• Security subsystem at edge of ESInet• All Calls and Data go through the BCF• Connects to the Internet (which is why it is needed)• Recommend at every point of ingress and egress

NG9-1-1 Call flow
1) LIS location sent to ECRF: 354 W 34th St, Houston, TX2) ECRF finds address point of: 354 W 34th St, Houston, TX3) ECRF determines Location is within the Houston PSAP4) ECRF sends Houston PSAP URI to the ESRP

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.)
