intent of this document
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 details
  • Not intended to make anyone an expert in NG9-1-1

  • 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
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
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 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 myths10
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 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 reality12
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
e9 1 1 vs ng9 1 1
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
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
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 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 1
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.

ng9 1 1 concepts
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 concepts40
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
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
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
Funding Challenges
  • PSAP Authorities must be allowed to accrue fundsto 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?

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
education50
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
