Outline
 Where we are

2010 prototype of E911 services

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

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

 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
11
2. Select the PSAP to answer the call
3. PSAP makes request to Location
Service for CALLER location
4. PIDF-LO object for CALLER location
returned to PSAP
5. 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
