  1. What Makes It Work?A Panel Discussion on Next Generation 9-1-1 Version 1.0 (June, 2014)

  2. Panel Members • Bob Currier, ENP – Intrado, Moderator • Jenna Green - Sprint • Bob Gojanovich, ENP – TeleCommunication Systems • April Heinze, ENP – Eaton County (MI) Central Dispatch • Pat Lustig, ENP – State of Oregon OEM • Marc Berryman, ENP – Mission Critical Partners • Nate Wilcox - Emergicom

  3. Agenda • Originating Service Providers • NG9-1-1 Core Systems • PSAP Equipment and Software • Databases and Call Routing • Security • Q & A

  4. Network Landscape

  5. Subscriber Impact • Any number of device types • Myriad of access options • Subscriber demographics • 9-1-1 Access EXPECTATIONS!

  6. Communication Service Provider • May be more than one • Transport of “call” • Data Management • Location • Subscriber Information • Inter-Connect with ESINet(s)

  7. CSP Responsibilities • Provisioning & Data Management • LIS – Location Information Server • CIDB - Call Information Database • PIDF-LO - Presence Information Data Format – Location Objects

  8. 9-1-1 Service Provider9-1-1 SSP • Deliver calls to PSAP • Selective Routing • Connectivity to ESInet

  9. Understanding the System of Systems NG9-1-1 Core Functions

  10. NG9-1-1 Ecosystem NG9-1-1 Core Services ESInet

  11. Next Generation 9-1-1 GIS Originating Networks GIS Data Management GIS CIDB LIS GIS ECRF LVF VoIP Discrepancies SIF ESInet BCF Access Control Enterprise BCF Admin PRF Cellular BCF Legacy Network Gateway NG9-1-1 PSAP ESRP Legacy SR Gateway Legacy PSAP Gateway PSTN Legacy PSAPs System Logging Legacy Selective Router Legacy E9-1-1 Networks This diagram is simplified for illustrative purposes.

  12. How NG9-1-1 Operates Build Me First! 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 Future Multimedia County C and X PSAPs Initial Deployment: Transitional LNGs Later: Direct IP interfaces Could be any combination of state, regional or county PSAPs

  13. PSAP Deployment Options • PSAP equipment is 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 deploy a hosted (shared) call handling system • PSAPs use LPGs to interface to core NG9-1-1 system, operating temporarily as `legacy PSAPs’ • Any combination of the above

  14. End-to-End IP - 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 ? Soon after wide NG9-1-1 availability Now 2014 2015 2016 2017 2018 2019 2020 

  15. Public Safety’s Goal • RELIABILITY • SECURITY • ROBUSTNESS • MAINTAINABILITY • ACCURACY • SCALABILITY

  16. Policy Examples • Outage • Call Flow • Call Overload • Maintenance • Type of Call, Caller • Others…..

  17. Operational • Coordination-Cooperation among agencies • System Administration • Methods and Procedures • Security • Training

  18. Education, Messaging • We are evolving to improve future 9-1-1 • Better 9-1-1 service in long term? • Meet Citizen’s Expectations

  19. Understand the System Next Generation 9-1-1 GIS Originating Networks GIS Data Management SIF GIS LIS GIS ECRF LVF VoIP ESInet GIS BCF Enterprise PRF Cellular BCF E9-1-1 Gateway i3 PSAP ESRP SR Gateway Legacy PSAP Gateway PSTN Legacy PSAPs Legacy E9-1-1 Networks Legacy Selective Router This figure is simplified for illustrative purposes

  21. Basic NG9-1-1 Call Flow LIS ESInet ECRF dial 9-1-1 BCF BCF ESRP Voice Text Video

  22. LIS LocationInformationServer • Location always provided by the LIS • Location can be civic address or geographic coordinate • Location by value or by reference • Locations for wireline may use existing ALI • Exceeds today's Location needs LIS

  23. LIS validates against the LVF LVF The locations in the LIS are validated against the provisioned GIS data in the Location Validation Function – the LVF LVF – The Location Validation Function

  24. LVF Location Validation Function • The Location Validation Function (LVF) validates the Location stored in the Location Information Server (LIS) • LVF uses Local 9-1-1 Authority GIS data for location validation • Gives Local 9-1-1 Authority total control of their data LVF Location Query LIS Location Response

  25. BCF BorderControlFunction • Security subsystem at edge of ESInet • All Calls and Data go through the BCF • Connects to the Internet (which is why it is needed) • Recommend at every point of ingress and egress BCF

  26. BCF BorderControlFunction • Firewall functions • Media Anchoring • Signaling protocol • Protocol Translation • Interworking • Codec negotiation • Support for emergency call transfer • Access Management • Admission Control BCF

  27. NG9-1-1 Call flow 1) LIS location sent to ECRF: 354 W 34th St, Houston, TX 2) ECRF finds address point of: 354 W 34th St, Houston, TX ECRF 3) ECRF determines Location is within the Houston PSAP 4) ECRF sends Houston PSAP URI to the ESRP psap.houston.tx.us Location + PSAP URI Location + Service URN Location + Service Identifier dial 9-1-1 PIDF-LO + URN: urn:service:sos PIDF-LO + PSAP URI sos@psap.houston.tx.us ESRP Voice Text Video

  28. ECRF EmergencyCall Routing Function • Same 9-1-1 Authority GIS Data as used in the Location Validation Function (LVF) • GIS data uses call location to Route “calls” to correct PSAP • You send it location (in civic or geo form) and it gives you back a URI of the PSAP to forward the call to

  29. ESRP Emergency Services RoutingProxy • Gets a location, queries ECRF • Uses URI from ECRF to send call to the correct PSAP • Applies a “Policy Routing Function” – Policy Based Routing • Policy can Override PSAP URI provided by ECRF

  30. Policy Routing Function ECRF PSAP B Location + PSAP URN PRF Location + Service Identifier PIDF-LO + PSAP URN sos@psap.harris_so.tx.us dial 9-1-1 PIDF-LO + URI: urn:service:sos PSAP A ESRP Voice Text Video

  31. Policy Examples • Outage • Call Flow • Call Overload • Maintenance • Type of Call, Caller • Others…..

  32. Security for an i3 NG9-1-1 ESInet • Security Credentials allows Interoperability • LIS uses ESRP and PSAP credentials for location dereference • ECRF / LVF accepts client credentials for routing / validation • PSAP operator certificate-based on authorization and access • Secure Communication and Privacy • Encryption of Data for Secure Storage and Transport • Protection from External and Internal Threats • Provides a security framework to protect NG9-1-1 systems

  33. Security Objectives • Develop a comprehensive Security Framework for NENA • Develop the minimum appropriate Security Standards for each component or area of the 9-1-1 system • (i.e. PSAP/CPE, Network, Providers, Database, etc)  • Work Cooperatively with other Committees and workgroups and outside agencies as necessary • Existing systems • Consider the use of existing information and standards when available and appropriate. • (i.e. DHS, NIST, ANSI, NLETS, etc.)
