NG9-1-1, NENA i3 and A9-1-1

Intrado Proprietary

NENA i3 and Next Generation 9-1-1 Florida 911 Coordinator’s Spring 2015 Meeting May - 2015 Mike Nelson Intrado, Senior Technical Officer

Selective Routers were designed In the ’70’s to route wireline calls.

Wireline calls are < 27% of

9-1-1 call volume.

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

Today’s Typical Legacy 9-1-1 Environment

5

Legacy Selective Router 9-1-1 Call Flow

1. Wireline (ANI) or Wireless (pANI) 9-1-1 Call 2. ESN

determined by ANI (or pANI)

3. Modified Analog TDM CAMA trunks

Legacy Telephone Network PSAP

PSAP receives legacy 9-1-1 call and “bids” ALI

4. ALI Bid or Rebid For Wireless: Location Updates

5. For Wireless Calls: interface carriers network, VoIP follows similar Dynamic ALI retrieval

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.

Next Generation (i3) Context

Emergency Services IP Network

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 9-1-1 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

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 9-1-1 attributes GIS data coordination is challenging Need “dispatch-able” addresses Different GIS data can cause

confusion across applications

i3 Dilemma

What’s Possible Today

versus

What’s Forward Looking

Transitional Models

Deploy Foundations

that Prepare for the Future

Purist versus Practical Paths to a NG9-1-1

Environment

Deployments today that are Solving Real

Problems

Environments that can deploy

enhanced information processing

There is much work to prepare for an i3 model

Different Methods of Location Delivery – Wireline Call

1. Traditional 9-1-1 Call (ANI)

2. Retrieve location information in PIDF-LO format

3. Invite w/ PIDF-LO

4. Given caller’s location determine destination

5. Invite w/ PIDF-LO


Originating Network

ESInet PSAP

PIDF-LO equals location information ALI without Name, Carrier, Class of Service

PSAP gets location delivered with call.

6. Retrieve additional call information (name)

HTTP protocol

19

IP Selective Router

1. 9-1-1 Call from Carrier to ESInet point of interface. Wireline (ANI) or Wireless / VoIP (pANI)

3. ESN

4. IP Protocols to PSAP equipment


• CAMA PSAPs use Legacy PSAP Gateway to convert to CAMA.

• IP PSAPs terminate SIP/RTP

5. ALI Bid or Rebid For Wireless: Location Updates

• Text • Real Time Text • Pictures • Video

• Carrier provided location (Same used for VoLTE )

Over the Top Applications (OTT) • 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.
