  1. Next Generation 9-1-1:A Game ChangerRoger HixsonNENA 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 9-1-1 industry • Focused on 9-1-1 systems and service evolution • The only professional organization solely focused on 9-1-1 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” 9-1-1 technology • Improve survivability • Network resilience, virtual PSAPs • Improve interoperability and information sharing

  7. How NG9-1-1 is Different • Technology • 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 • Improved services are timeframe interdependent between carriers, other originating providers, and NG9-1-1 Carriers IP interface Carriers Multimedia ES Public Safety Internet Providers Implement IMS Implement MMES Transition to NG9-1-1 IP based Multimedia ?

  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

  14. NG9-1-1 Common BenefitsPSAPs and Responders • Text/IM to 9-1-1 • Files to 9-1-1 , 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: • Language preference of caller • Type of technology >IM, Sensor, Satellite phone

  16. NG9-1-1 Responder Benefits • Informative data to dispatch and field responders • National standards for data interfaces • Adaptable for future needs • Text/IM via 9-1-1

  17. Next Generation 9-1-1 Building Blocks Public Education Management, Maintenance & Training Procedures NG9-1-1 Core Services (i3 Applications) Interconnection / Interoperability / Security IP Network Infrastructure - ESInet Governance and Policy

  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)

  19. NG9-1-1 Logical Links • DB Mgmt • GIS • ALI • Policy Routing • etc Functional Entities NIF PSTN LIF GIS “ALI” ESInet LIS – Location Information Server HELDETC LoST LoST ECRF – Emergency Call Routing Function SS7E-MF CO/SR SIP LNG/LSRG - PIF SS7E-MF SIP NG PSAP SIP BCF – Border Control Function CO/SR SIP ESRP – Emergency Services Routing Proxy SIP LNG/LSRG - PIF SS7E-MF IP SIP SIP IP Host Host Client CO/SR TDM LPG Legacy PSAP Internet and Other ESInet’s The `i3’ specification describes the technical functions and interfaces

  20. Call Flow – Legacy Wireless Example 2) Location information for caller/device is retrieved 3) (optional) Initial routing instructions are retrieved VoIP (i2) Call 6) The NG9-1-1 call routing system determines final routing instructions using GIS data and policy rules Location Source ESINet Call Routing Incoming Gateway PSAP Gateway 4) Call is sent to the security edge 1) Caller dials 9-1-1 LegacyWireline LegacyWireless Border Control 5) The call passes security checks Call Delivery Native IP NG9-1-1PSAP LegacyPSAP Static 7) If the PSAP is i3-capable, the call is routed directly to the PSAP

  22. 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 County B and 5 PSAPs Wireless MSCs 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 9-1-1 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?

  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 9-1-1 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
