Transcription

1 NENA i3 and Next Generation Florida 911 Coordinator s Spring 2015 Meeting May Mike Nelson Intrado, Senior Technical Officer Intrado Proprietary

2 Selective Routers were designed In the 70 s to route wireline calls. Wireline calls are < 27% of call volume. 2

3 Emergency Services Ecosystem Integrated services across the extended situational timeframe Expanded set of collaborating participants and role players Contextual awareness with automated services and what may seem like disparate information 3

4 4 Today s Typical Legacy Environment

5 Legacy Selective Router Call Flow Originating Network Legacy Telephone Network PSAP MSC LDE 5. For Wireless Calls: interface carriers network, VoIP follows similar Dynamic ALI retrieval 4. ALI Bid or Rebid For Wireless: Location Updates Caller 1. Wireline (ANI) or Wireless (pani) Call 2. ESN determined by ANI (or pani) 3. Modified Analog TDM CAMA trunks Call Taker PSAP receives legacy call and bids ALI 5

6 What is Next Generation 9-1-1? Dedicated Public Safety Grade IP Network (ESInet) Based on Caller s Location Delivering Calls, Data and Advanced Services Integrated Operating Environment Interactions across domains with intelligent clients implementing advanced services. 6

7 Next Generation (i3) Context Emergency Services IP Network 7

8 i3 Foundation Elements IP Network ESInet Addressing, security, interconnection, management Geographic Data Location Validation, Jurisdictional boundaries Location Information Fundamental to target architecture IP Enabled Functional Elements Changes call processing techniques and system interfaces Additional Data Call, Caller and Event Operating & Business Environment Funding situations vary across the United States End state is dependent on Telecommunication Industry changes Ultimately changes call data (location) provisioning responsibilities 8

9 Geographic and Address Data Coordination of Address and Geographic Data GIS Coordinators (e.g., County) Postal Addresses (Civic or textual) Call Taking and Dispatch (CAD) ALI and MSAG (transitional) Enhanced Data Services Routing Data GIS Polygons (with Latitude and Longitude) Equivalent (or better) results to current Selective Router database Public Internet Interconnection ECRF / Forest Guide Hierarchical Routing Rules GIS with attributes GIS data coordination is challenging Need dispatch-able addresses Different GIS data can cause confusion across applications 9

10 10 Context of NENA i3 Functions

11 11 NENA i3 Vision (simplified)

12 i3 Protocols Originating Network ESInet PSAP Services LoST HTTPs HELD LoST Caller LoST SIP (PIDF-LO) LoST HELD SIP (PIDF-LO) Call Taker Terminating ESRP Data Management Location, Subscriber Data Management GIS Boundaries, Policy Rules, ESInet 12

13 i3 Call Flow- Location by Value Originating Network ESInet PSAP 1. UA Queries for Location 2. UA queries for first route 4. ESRP queries for routing Caller 3. INVITE (PIDF-LO) 5. INVITE (PIDF-LO) Call Taker 13

14 i3 Call Flow- Location by Reference Originating Network ESInet PSAP 1. UA Queries for Location and Obtains Reference 3. ESRP dereferences location 4. ESRP queries for routing Caller 2. INVITE (Loc Ref) 5. INVITE (PIDF-LO, Ref) Call Taker 14

15 Post Call Setup Interactions Originating Network ESInet PSAP PSAP dereferences location HELD LoST SIP HTTPs Any Validated User Agent Services and Information 15

16 i3 Dilemma There is much work to prepare for an i3 model Environments that can deploy enhanced information processing services What s Possible Today versus What s Forward Looking Deploy Foundations that Prepare for the Future Deployments today that are Solving Real Problems Transitional Models Purist versus Practical Paths to a NG9-1-1 Environment 16

17 17 NENA i3 Transitional Elements

18 Different Methods of Location Delivery Wireline Call Originating Network ESInet PSAP 6. Retrieve additional call information (name) 2. Retrieve location information in PIDF-LO format HTTP protocol Caller 1. Traditional Call (ANI) PIDF-LO equals location information ALI without Name, Carrier, Class of Service 3. Invite w/ PIDF-LO 5. Invite w/ PIDF-LO 4. Given caller s location determine destination Call Taker PSAP gets location delivered with call. 18

19 IP Selective Router Originating Network ESInet PSAP MSC LDE 6. For Wireless Calls: interface carriers network, VoIP follows similar Dynamic ALI retrieval 5. ALI Bid or Rebid For Wireless: Location Updates Caller Call from Carrier to ESInet point of interface. Wireline (ANI) or Wireless / VoIP (pani) 2. IP Protocols SIP and RTP 3. ESN 4. IP Protocols to PSAP equipment Call Taker CAMA PSAPs use Legacy PSAP Gateway to convert to CAMA. IP PSAPs terminate SIP/RTP 19

20 Call Signaling and Audio Interactions Originating Network ESInet PSAP Call Setup. Additional Parties can be added or call can be completed. RTP Audio Path 4. Bridge setup 3. Create a bridge 6. 3-way bridge Audio Path Caller Call Signaling and Audio call arrived 5. SIP Invite Customer Premise Equipment 20

21 Different Methods of Location Delivery Mobility Call Originating Network ESInet PSAP MSC LDE 6. Initial location and location updates given the URI 2. Create and return URI Caller 1. Wireless Call (pani) 3. Invite w/ URI 4. ESN determined by pani 5. Invite w/ URI Call Taker PSAP implements all NENA i3 interfaces 21

22 22 Transitional Models Support multiple Routing Methods

23 Public Safety Migration Steps to NG9-1-1 Foundation Elements Establish Core ESINet Infrastructure (IP Network and Softswitch) IP PSAP GIS Data Preparation (Location Validation, Routing, Service Identification) Advanced Applications and Data Services Additional Requests for Assistance Types Evolution of the overall environment(s) (Roles, Regulations, Tariffs, Funding, Incumbents, FCC, State ) Establish i3 core functions while managing transitional elements Carrier s establish LIS and deliver a routable PIDF-LO with call setup i3 NENA vision endstate fully realized Many paths and steps to the long term NG9-1-1 vision Interoperate with changing Telecommunications Industry (LVF, E-CSCF, IMS, NNI, IETF, Internet) i3 vision issue resolutions Today Months Years Many Years 23

24 24 IP PSAP Server Configurations

25 Network Resiliency Considerations Multiple paths Route Evaluation and Re-routes Quality of Service packet prioritization Points of Interface Failure scenarios Security 25

I am in a closet Carrier: Hawaii Cellular Cell Address: 123 Main Street, Kauai Cell X/Y: 22.08N 159.5W Cell Uncertanty:1609 PSAP: Kauai Police 332 Emi road, Koloa Carrier provided location (Same used for VoLTE ) I am hiding in the master closet. Please hurry This is What is your exact location 1 0:26 Over the Top Applications (OTT) The Police are on the way. Stay hidden Independent of carrier OTT provider must verify identity of user Must trust OTT provider for validity of subscriber Apple imessage, Blackberry Messenger Application must provide location Works across multiple platforms and carriers Supports roaming Could provide additional information from user Medical, contacts, addresses, bread crumbing, etc. 35
