Welcome to the
NENA NG9-1-1 Tutorial
as of March 6, 2011
[To see animation, run in PowerPoint presentation mode]
Intent of this Document
Present information on NG9-1-1 and the transition to it
Provide a high level overview to make you conversant
Not a complete picture with all the detailsNot intended to make anyone an expert in
NG9-1-1
The 9-1-1 Service Processfrom 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 GOINGAND
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
TransitionTwo 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 NG9-1-1NG9-1-1 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 end-state
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 NG9-1-1Describes 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.

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.
ESInet Concept
The ESInet is the red lane on this data superhighway. NG9-1-1 and other emergency services application sets run on the ESInet.IP network logical segment = ESInet for emergency services call traffic
The blue lanes are for other non-emergency services

NG9-1-1 ConceptsThink 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 PSAPFusion CentersVirtual PSAPsTrauma CentersPoison ControlEmergency Operations Centers
NG9-1-1 ConceptsMore direct control of system capabilities by
9-1-1 Authorities and PSAP managementGIS data updated electronically, to control
validation and routingElectronic access to interactive validation data
by service providersRouting 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 ChallengesCosts
Most pricing is custom at this stageDouble costs during transition
Relationship of cost to implementation scopeBigger 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 providerYour NG9-1-1 IP infrastructure provider to be
different than your NG9-1-1 services providerChoice of service providers
See:NENA NG9-1-1 Transition Policy Implementation Handbook
Funding ChallengesPSAP 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 feesMore sources/lower fees?
NG9-1-1 User BenefitsThe light at the end of the tunnel…

EducationNENA/APCO Joint Education Steering Committee
Formed late Spring 2010Reviewing identified stakeholder groupsAssessing/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
EducationChallenges
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
