Outline
Where we are2010 prototype of E911 services
How we got here Implementation of mobile telecommunications standards Implementation of localization and geospatial standards
Where we are goingExtend E911 scenario and prototype indoors Implement other localization and geospatial standards required
to accomplish this

Standards Used to Improve Situational Awareness in E911 Prototype 3GPP IMS to
provide a SIP/IP core network infrastructure
route 911 calls OMA LOCSIP to
convey terminal locations OMA Presence SIMPLE to
publish status and notifications OMA SUPL to
perform network-based position determination of terminals
perform device-based position determination of terminals
IETF LoST to select the PSAP to answer 911 calls
GSMA RCS to publish locations and presence perform user-based position
determination of terminals IETF HELD to
perform network-based position determination of terminals
WiMAX to transmit and receive voice, video,
and other situational data 3G-GSM Networks to
transmit/receive situational data perform network-based position
determination of terminals

Let’s Take E911 Indoors
Our technology demos have considered only outdoors emergency scenarios
We now plan to extend the testbed by moving the emergency scenario indoors
IETF PIDF-LO, OMA SUPL are existing standards that are being extended to support indoor locations and context.
Even richer context could be provided by OGC CityGML.

Seamless Outdoors/Indoors Contextualization
8
New Context and Requirements
Extensions to scenario Fire within Chemistry Building Need to provide indoor navigation support to
emergency responders New Requirements
Indoor localization network- Seamless transition between world and local coordinate
systems- Accurate real-time positioning
Building Information Model (BIM) catalog services- Feature-rich model of building interior- Content and access-descriptive metadata for BIM- Catalog service to help find BIM for a location
BIM data services (WFS)- Application to extract and return floorplan(s)
BIM LBS (WMS)- Contextualize indoor location with floorplan- Compute current location and routing information
More Standards

Indoor E911 Enablers –
Geospatial Standards OGC OGC 06-121r9, OGC® Web Services Common Implementation OGC 07-006r1, OGC® Catalogue Service Implementation OGC 06-042, OGC® Web Map Service (WMS) Implementation OGC 09-025r1, OGC® Web Feature Service Interface Standard (also
ISO 19142) OGC 08-007r1, OGC® City Geography Markup Language (CityGML)
Encoding OGC 07-074, OGC® Location Service (OpenLS) Implementation:
Core Services

Indoor E911 Enablers – Other Standards
IETF PIDF-LO Provide Indoors Civic/Geodetic coding Provide Relative Location Georeference World CRS – Local CRS
GSMA RCS Publish indoor/outdoor locations and presence Perform user-based position determination of terminals, indoors and
outdoors
OMA Presence SIMPLE Improve situational awareness through status publish and
notifications based on indoor extensions to PIDF-LO
OMA LOCSIP Convey indoor and outdoor terminal locations Make outdoors/indoors transition more seamless

Proposed Geospatial Enhancements to E911 Prototype 1. 911 call made by CALLER
2. Select the PSAP to answer the call3. PSAP makes request to Location
Service for CALLER location4. PIDF-LO object for CALLER location
returned to PSAP5. PSAP client queries OGC CS for
geospatial data objects whose envelopes contain PIDF-LO location
6. OGC CS returns list of geospatial data objects that contain CALLER‘s location, e.g., maps, images, documents and CityGML building models, along with URIs/URLs for each.
7. PSAP application selects data objects of interest, e.g., a CityGML building model, and requests a floorplan map from an OGC WMS.
8. OGC WMS requests floorplan features from the OGC WFS that manages them.
9. OGC WFS returns floorplan features to the OGC WMS.
10.OGC WMS builds floorplan map from features and returns it to the PSAP client.
11.PSAP client application (or another’s application service) computes and displays navigation route to CALLER using responder’s current location and floorplan.

Significance of E911 Prototyping Activities to Geospatial Community
Demonstrate the value that standards offer to network communications for managing emergencies
Provide feedback to standards forums based on experiences from our demonstrations
Expose opportunities to enhance and integrate standards in ways critical for meeting the needs of decision-makers and emergency response teams
