1. Next Generation 9-1-1: A Game Changer Roger Hixson NENA Technical Issues Director

2. NENA History 30 years as a non-profit association for 9-1-1
25 years of E9-1-1 and NG9-1-1 standards
7000+ members from public safety and the industry
Focused on systems and service evolution
The only professional organization solely focused on policy, technology, operations, and education issues

3. Why NG9-1-1? ~330 million connected wireless devices in the U.S.
Population is approximately 313 million
Wireless-only households are on the rise
~32% of adults & 36% of children live in wireless-only households
More than 98% of Americans have access to 3G or 4G services
Statistics courtesy CTIA & MobileFuture

4. Why NG9-1-1? (cont’d) Exponential increases in text messaging
More than 8 trillion texts sent last year
Up 1.1 trillion from the previous year
34 million Americans who are deaf or hard of hearing rely on texting
Callers expect to be able to use `normal’ methods
for emergency communications: text, pictures,
video, even sensors
Statistics courtesy CTIA & MobileFuture

5. NENA & NG9-1-1 NG9-1-1 and features conceptualized in 2001
Began Requirements development in 2003
Began technical development in 2004
NENA is the primary standards development organization for NG9-1-1
Completed many standards and documents to date

6. What’s Driving NG9-1-1? Newer technologies/services
Text, image, video, telematics, sensors, subscriber info, emergency location info
Need to “mainstream” technology
Improve survivability
Network resilience, virtual PSAPs
Improve interoperability and information sharing

7. How NG9-1-1 is Different Technology Interoperability
IP Packet Based vs Circuit Switched
Interoperability
No longer a “local” service
Interoperates at county, region, state and national levels

8. How NG9-1-1 is Different (cont’d)
Functionality
Replicates E9-1-1 capabilities
and
Adds new capabilities, direct control options
Wide ranging additional data options
GIS-based instead of tabular data for location validation and routing control 

9. How NG9-1-1 is Different (cont’d)
IP SIP based (all call handling is SIP based)
Uses numerous IETF RTFs, such as ECRIT, INVITE, REFER, BYE, PIDF-LO
Example functional areas:
Location Validation Function (GIS based)
SIP ingress and call routing control (ESRP with ECRF)
SIP delivery of call and data (multimedia supported)
Queries for wide range of added data

10. All IP end-to-end - Timeframes

13. The Nature of NG9-1-1 Designed to support interoperability
Designed with open standards
Designed for and enables open competition
Enables a transition to competitive service provider environment
Necessitates regulatory (and legislative) change
Stress local, state, national Interoperability objectives – only achievable with national and international standards

14. NG9-1-1 Common Benefits PSAPs and Responders
Text/IM to 9-1-1
Files to , such as photos or video clips
Streaming video
Telematics and sensor data
Additional Data available

15. NG9-1-1 PSAP Benefits Virtual PSAP (geographically distributed)
NG9-1-1 controlled to individual or hosted CPE
Nomadic and/or mobile call taker workstations
Policy-based alternate routing with new options
To alt PSAP, or spreading calls to multiple PSAPs
Invoked directly within minutes by PSAPs (online)
Additional Policy-based routing for:

18. How NG9-1-1 Operates
Similar to E9-1-1, core NG9-1-1 system is established for use by multiple Counties and PSAPs
Then PSAPs begin to utilize NG9-1-1, depending on the PSAP capabilities (IP interface, software, training, etc)

NG9-1-1 System = technical architecture, plus the various databases that provide information and control of the system, plus the operational procedures, for both the system itself and the users.

22. ECRF, ESRP, LVF, GIS, Policy Mgmt, Process Mgmt
How NG9-1-1 Operates
Installed first, then
utilized by State, Region, or County PSAPs, others
County A and 17 PSAPs
Wireline COs
Core NG9-1-1 System
ECRF, ESRP, LVF, GIS, Policy Mgmt, Process Mgmt
Wireless MSCs
County B and 5 PSAPs
VoIP
County C and X PSAPs
Next is Multimedia
Transitional LNGs and then IP interfaces
Could be state or regional sets of Counties

23. PSAP Utilization of NG9-1-1
Multiple options depending on how each Authority proceeds, and individual PSAP status
PSAP equipment 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 convert to common use of hosted interface equipment
Some PSAPs use LPGs to interface to core NG9-1-1 system, operating temporarily as `legacy PSAPs’
Or any combination of above choices

24. PSAPs and NG9-1-1 PSAPs utilize core NG9-1-1 system features as able
But, when core NG9-1-1 is in place, all PSAPs are on NG9-1-1 whether each PSAP is NG9-1-1 capable or not
The core, multi-county or state NG9-1-1 system is not deployed “PSAP by PSAP”
Training for PSAP personnel is critical, both for calltaking and for data base management

25. Operational Changes with core NG9-1-1
Using GIS data for validation and routing control
Transition wireless ESRK -> location conversion data
Using Policy Routing features to control alternate routing, overflow control, disaster management, and Virtual PSAPs (if utilized)
Accessing additional data not previously available
Likely need a central DB management group

26. PSTN -> IP Telecomm
For emergency communications, support customer needs as soon as possible
Understand and be prepared for the transition, rather than just reacting to it
IP interface for 9-1-1, Multimedia capability
Push for priority standards development

27. PSTN -> IP Telecomm
E9-1-1 must continue to be supported during the national transition to NG9-1-1
Analog technology support (re E9-1-1) can be retired over time = cost savings for carriers and Public Safety

28. Benefits of All IP end-to-end
Carrier customers able to fully utilize text and multimedia for emergency communications
After transition, less carrier cost to support emergency communications
IP end-to-end (caller to PSAP) enables more rapid integration of carrier service features and upgrades that enable or affect emergency communications
others?

29. Discussion NENA: The 9-1-1 Association

30. Thank You! NENA: The 9-1-1 Association

31. Text to 9-1-1

32. Carrier SMS National Interim Text to 9-1-1
Four forms of Text for emergency communication:
Vendor / Over The Top (OTT) offerings
Initial forms of Interim Text to 9-1-1
National SMS Interim Text – carrier based
Long Term Text integrated via NG9-1-1

33. Vendor / Over The Top (OTT) offerings
non-carrier text approaches (often installed PSAP by PSAP or County based), handled locally by Public Safety
NENA Education Committee has generated a Guide document on what Public Safety people need to ask vendors when they are approached. 
a Q&A document was produced for App providers to give them better knowledge of what involves, re their design and communications with potential Public Safety customers.

34. Initial forms of Interim Text to 9-1-1
Intermediate trials of carrier involved text via vendors, such as are going on in parts of Texas, Tenn, Virginia, etc
Similarities to National SMS Interim Text
Some versions deliver text only to a remote web server
May converge to the National SMS approach
Could continue as standalone methods in addition to National approach

35. Carrier SMS National Interim Text to 9-1-1
National SMS Interim Text – carrier based
Utilizes the ATIS/TIA Text Control Center (TCC) standard
True national focused SMS Interim Text to 9-1-1, as is being recommended to the FCC by the EAAC Advisory group
National group working on establishing common methods and procedures across all carriers and TCC providers to meet May 15, 2014 service date

36. Carrier SMS National Interim Text to 9-1-1
Delivers text to the PSAP
Via one of several optional interfaces chosen `by PSAP’
Using TTY, Internet, IP to local server, NG9-1-1
PSAP can automatically capture content and logging info
It has been suggested that each PSAP can choose when and if to take SMS Interim Text
Let’s talk about that……

37. Long Term Text integrated via NG9-1-1
Will utilize IMS and MMES to interface to NG9-1-1 using IP
Designed to allow maximum PSAP operational benefits
Ability to handle carrier based text end to end in any given area depends on availability of IMS, MMES, and fairly complete NG9-1-1 features
Ability to handle text from Internet service providers depends on NG9-1-1

38. Text and 9-1-1
Any version could continue in parallel with national SMS
Many of them have features beyond text
All PSAPs, or delegates, will need to accept national SMS Text in order to provide consistent service across the nation
Caller ability to effectively utilize emergency text when needed requires common solution nationwide, and NG9-1-1 as soon as possible
