transition to it
 Provide a high level overview to make you
conversant
 Not a complete picture with all the details
 Not intended to make anyone an expert in
NG9-1-1
The 9-1-1 Service Process
from Caller to Calltaker and Beyond

- The Access Provider and the Service Provider are often the
same company, but do not have to be.
- The E9-1-1 Network is usually built to support multiple
counties, but may be sold to individual counties.
-* There does not have to be a Service Provider at all

What’s Driving NG9-1-1
- Newer Technologies/Services
- Text, Image, Video, Telematics, Sensors,
Subscriber Info
- Improve Survivability
- Network Resilience, Virtual PSAPs
- Improve Interoperability and
Information Sharing
- Need to “Mainstream” 9-1-1
Technology
How NG9-1-1 is Different
-
Technology:
-Packet Based vs Circuit Switched
- Functions:
-Replicates E9-1-1 capabilities
-Adds new capabilities
-GIS vs Tabular MSAG
- No longer a ‘local’ service:
-Interoperability at county, region, state and national
levels
NG9-1-1 Myths
 NG9-1-1
will cause a PSAP to be overwhelmed with
more and new data elements from new types of
devices
 NG9-1-1 will improve wireless and nomadic VoIP
E9-1-1 accuracy and routing
 NG9-1-1 will make text-to-9-1-1 available to all
callers
 NG9-1-1 will eliminate prank or harassing calls
NG9-1-1 Myths
 NG9-1-1 will enable call back to Non-Service
Initialized (NSI) wireless handsets
 NG9-1-1 will save money
 All connected devices will know and report
their own locations without action by the PSAP
 NG9-1-1 will eliminate all known and
unknown issues with E9-1-1 and usher in
an era of peace and prosperity
NG9-1-1 Reality
• NG9-1-1
by itself will not enable text to 9-1-1
•NG9-1-1 is designed to support text when available
•Standards work is underway in the wireless industry
to support future types of text messages
• NG9-1-1 will not eliminate prank or harassing
calls
• NG9-1-1 will not enable call back to NSI
wireless devices
NG9-1-1 Reality
 NG9-1-1 will enable more - but it may not cost
less.
 In the short term, overall costs will be higher
because legacy networks must be maintained
while NG9-1-1 systems are being deployed
 NG9-1-1 defines what information is
desired/required from originating networks,
but does not define how those networks
function internally
WHERE ARE WE GOING
AND
HOW DO WE GET THERE?
E9-1-1 vs NG9-1-1
 Complex analog trunking
and data network
 Class 5 switch for Selective
Router
 Translation based control
 Limited to voice calls
 Data bandwidth 20 char
(digits)
 Complex Emergency
Gateway Network for VoIP
 Custom interfaces for
each service type
 Engineered, managed IP
networks (ESInet)
 IP software selective routing
function
 GIS and database controls
 Voice, text, video
 Bandwidth unlimited
 Direct handling of Internet
sourced calls
 Standard IP interface
for all service types
Transition
 Two basic ways
Conversion from today’s 9-1-1 direct to NENA
defined NG9-1-1 using transitional interfaces
Using an interim IP system approach, then
converting to NG9-1-1
Transitional NG9-1-1
 NG9-1-1 is designed to use IP end-to-end - where
mainstream telecommunications is headed
 To avoid major design changes in the future, the core
architecture (NENA `i3’) is oriented to the expected endstate
In the meantime…
 Gateways in and out will allow current OSP and PSAP
interfaces to work during transition
 Current cellular and VoIP location data processes are
accommodated until they convert to IP interactions
Baseline NG9-1-1
 Describes a basic set of features & functions that
constitute a NENA Standards-based Next Generation 9-1-1
solution, on the path to an end-state i3 architecture. ..
 …Must include the functions of today’s E9-1-1 system,
replicated in IP protocol and structures as defined by
NENA NG9-1-1 standards, including all network and PSAP
components of the system …
 …The basic ability to support non-voice multimedia, such
as text and video.

ESInet within IP network
Terminology
 Emergency Services IP Network (ESInet)

A privately managed IP transport network that may be
shared by multiple agencies
 i3 Standard requirements, architecture and
functions
 Including the Emergency Services Routing Proxy (ESRP)
and the Emergency Call Routing Function (ECRF).
 NG9-1-1
 The set of network elements, software applications,
databases, CPE components, and operations &
management procedures required to provide
Next Generation emergency services.
ESInet
• Combination of
multiple
transports.
• Can interface
with other
networks.
• Coexistence
with other ES
applications.

NG9-1-1 Concepts
 Think of your NG9-1-1 system as one element of an
interconnected public safety and security system
 County - Regional – State – National – International
 Expansion of, and beyond the traditional PSAP
 Fusion Centers
 Virtual PSAPs
 Trauma Centers
 Poison Control
 Emergency Operations Centers
NG9-1-1 Concepts
 More direct control of system capabilities by 9-1-1
Authorities and PSAP management
 GIS data updated electronically, to control validation
and routing
 Electronic access to interactive validation data by
service providers
 Routing control and options controlled in databases
directly accessible from 9-1-1 Authority and PSAP
database terminals, or other authorized remote access
points
NG9-1-1 Challenges
 Costs
 Most pricing is custom at this stage
 Double costs during transition
 Relationship of cost to implementation scope
 Bigger geography equals better price performance
 Jurisdictional Impacts
 If multiple services on ESInet, who is in charge?
 Shared usage and costs means shared responsibilities
Regulatory Challenges
 Regulations Should Allow:
 Your NG9-1-1 provider to be different than your current
E9-1-1 provider
 Your NG9-1-1 IP infrastructure provider to be different
than your NG9-1-1 services provider
 Choice of service providers
See:
NENA NG9-1-1 Transition Policy
Implementation Handbook
Funding Challenges
 PSAP Authorities must be allowed to accrue funds
to build ESInets and NG9-1-1 while still paying for
and operating legacy networks
 Consider different funding sources:
 IP access providers?
 Pre-paid wireless?
 Consider new payment terms for 9-1-1 fees
 More sources/lower fees?
NG9-1-1 User Benefits
The light at the end of the tunnel…
 Text/IM to 9-1-1
 Files to 9-1-1 , such as
photos or video clips
 Streaming video
 Telematics and sensor
data
 Nomadic and/or
mobile call taker
workstations
 PSAP “on-the-fly” or
Virtual PSAP
 Policy-based alternate
routing with new
options
 Additional Policy-based
routing for:
Language
preference of caller
Type of technology
in use (IM, Sensor,
Satellite phone,
etc.)

Education
NENA/APCO Joint Education Steering Committee
 Formed late Spring 2010
 Reviewing identified stakeholder groups
 Assessing/Identifying requirements for
stakeholders that will need to better understand
some or all aspects of NG9-1-1
 Working with NENA EAB and APCO Institute for
education delivery
Education
Challenges
 Must baseline everyone’s level of understanding of
NG9-1-1 before more material is introduced
 Which topics are the most critical?
 How much content is “too much” ?
 Identify effective delivery methods for targeted
topics and stakeholders
