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

(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?

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
