  1. Welcome to theNENA NG9-1-1 Tutorialas of March 6, 2011[To see animation, run in PowerPoint presentation mode]

  2. 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

  3. The 9-1-1 Service Processfrom Caller to Calltaker and Beyond Caller Access Provider Service Provider* E9-1-1 Network PSAP CPE Telecommunicator • 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

  7. 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

  8. 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

  9. 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

  10. 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

  11. 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

  12. 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

  13. Where are we goingand How do we get there?

  14. 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

  15. 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

  16. 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

  17. 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.

  18. NG9-1-1 Basics NG9-1-1 System Procedures + Databases + i3 Architecture + ESInet within IP network

  19. Terminology • Emergency Services IP Network (ESInet) • 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.

  20. ESInet • Combination of multiple transports. • Can interface with other networks. • Coexistence with other ES applications.

  21. ESInet Concept “I-95” Poison Control The blue lanes are for other non-emergency services N11 / CAD-to-CAD IP Network IP Radio Law, Fire, EMS 9-1-1 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

  31. The Nature of NG9-1-1 • Designed to support interoperability • Designed with open standards • Designed for and enables open competition by component through interface standards • Enables a transition to competitive service provider environment • Causes a need for regulatory (and legislative) change

  32. NG9-1-1 Added Features • GIS based routing control • Location data transported with the call • Additional types of calls and messaging • Additional data • Virtual PSAP capabilities • Added alternate routing options (ex: sensing PSAP status) • Direct control of call management [PRF] • ?

  33. How an NG9-1-1 Call Works

  34. Basic Call Flow in NG9-1-1 GIS Location to Service Translation (LoST) GIS Data Layers LIS ECRF Device acquires location before a call is made Location Query to Location InformationServer(LIS) Location response (civic or geo) – pre-validated Device (or network) queries ECRF for routing ECRF provides next hop routing - ESRP 1 Originating Network ESInet

  35. Basic Call Flow in NG9-1-1 LoST LIS ECRF ESRP 1 Call is placed Call is sent to ESRP 1 with the location LIS is re-queried for any updates to location Can be ALI ESRP queries ECRF for next hop Originating Network ESInet

  36. Basic Call Flow in NG9-1-1 LoST LIS ECRF ESRP 1 ESRP 2 “Next Hop” Routing Call is sent to ESRP 2 with location LIS is re-queried to update location ECRF is queried for next hop Originating Network ESInet

  37. Basic Call Flow in NG9-1-1 LoST Policy Rules LIS PRF ESRP 1 ESRP 2 “Next Hop” Routing Policy Rules are evaluated at each hop Call is sent with location to PSAP LIS is queried to obtain any updated location information Originating Network ESInet

  38. Basic Call Flow in NG9-1-1 LoST LIS PRF ESRP 1 ESRP 2 Media Call is Connected to PSAP Media is established between PSAP and caller Media can be any combination of Voice, text, data, video, etc… LIS is queried for any updated location information Originating Network ESInet

  39. 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

  40. 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

  41. 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

  42. 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

  43. 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?

  44. NG9-1-1 User BenefitsThe light at the end of the tunnel… • Text/IM to 9-1-1 • Files to 9-1-1 , such as photos or video clips • Streaming video • Telematics and sensor data • Nomadic and/or mobile call taker workstations • PSAP “on-the-fly” or Virtual PSAP • Policy-based alternate routing with new options • Additional Policy-based routing for: • Language preference of caller • Type of technology in use (IM, Sensor, Satellite phone, etc.)
