1 What Makes It Work? A Panel Discussion on Next Generation 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 4

5 Subscriber Impact Any number of device types Myriad of access options Subscriber demographics Access EXPECTATIONS! 5

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

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

8 9-1-1 Service Provider SSP Deliver calls to PSAP Selective Routing Connectivity to ESInet 8

9 NG9-1-1 CORE FUNCTIONS Understanding the System of Systems 9

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

12 How NG9-1-1 Operates Core NG9-1-1 System ECRF, ESRP, LVF, GIS, Policy Mgmt, Process Mgmt Wireline COs Wireless MSCs VoIP County A and 17 PSAPs County B and 5 PSAPs County C and X PSAPs Could be any combination of state, regional or county PSAPs Future Multimedia Build Me First! Initial Deployment: Transitional LNGs Later: Direct IP interfaces 12

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 13

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 14 Implement IMS Implement MMES Transition to NG9-1-1 IP based Multimedia ? Now  Soon after wide NG9-1-1 availability

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 Better service in long term? Meet Citizen’s Expectations

20 Originating Networks LIS VoIP Cellular PSTN Enterprise BCF ECRF BCF ESRP ESInet NG9-1-1 PSAP GIS LVF Where are the Databases? GIS GIS Data Management SIF Policy Store Policy Routing Function (PRF)

21 NENA Copyright 2014 ESInet dial ESRP ECRF BCF Basic NG9-1-1 Call Flow LIS Voice Text Video

22 NENA Copyright 2014 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 Location Information Server LIS

23 NENA Copyright 2914 The locations in the LIS are validated against the provisioned GIS data in the Location Validation Function – the LVF LVF – The Location Validation Function LVF LIS validates against the LVF

24 NENA Copyright 2014 LVF Location Validation Function The Location Validation Function (LVF) validates the Location stored in the Location Information Server (LIS) LVF uses Local Authority GIS data for location validation Gives Local Authority total control of their data Location Query Location Response LVF LIS

25 NENA Copyright 2014 BCF 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 Border Control Function BCF

26 NENA Copyright 2014 BCF Firewall functions Media Anchoring Signaling protocol Protocol Translation Interworking Codec negotiation Support for emergency call transfer Access Management Admission Control Border Control Function BCF

27 NENA Copyright 2014 Location + Service Identifier PIDF-LO + URN: urn:service:sos dial ESRP ECRF PIDF-LO + PSAP URI Voice Text Video Location + PSAP URI NG9-1-1 Call flow 1) LIS location sent to ECRF: 354 W 34 th St, Houston, TX 2) ECRF finds address point of: 354 W 34 th St, Houston, TX 3) ECRF determines Location is within the Houston PSAP 4) ECRF sends Houston PSAP URI to the ESRP psap.houston.tx.us Location + Service URN

28 E mergency C all R outing F unction ECRF Same 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 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 Emergency Services Routing Proxy

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

32 NENA Copyright 2013 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 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.)
