2 Outline Where we are 2010 prototype of E911 services How we got here Implementation of mobile telecommunications standards Implementation of localization and geospatial standards Where we are going Extend E911 scenario and prototype indoors Implement other localization and geospatial standards required to accomplish this
3 E911 Scenario Used for Prototyping
4 PSAP HELD LIS Location Server Presence Server LOST Server Resource List Server HSS IMS Core I-CSCF P-CSCF E-CSCF LRF S-CSCF PGFD Fire Chief UMDP Patrol Car WiMAX Network LOCSIP Servers E911 Prototype (2010) 911 Caller 3G-GSM Network
5 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
6 Lets 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.
7 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
9 Indoor E911 Enablers – Geospatial Standards OGC OGC r9, OGC ® Web Services Common Implementation OGC r1, OGC ® Catalogue Service Implementation OGC , OGC ® Web Map Service (WMS) Implementation OGC r1, OGC ® Web Feature Service Interface Standard (also ISO 19142) OGC r1, OGC ® City Geography Markup Language (CityGML) Encoding OGC , OGC ® Location Service (OpenLS) Implementation: Core Services
10 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
11 Proposed Geospatial Enhancements to E911 Prototype call made by CALLER 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 CALLERs 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 anothers application service) computes and displays navigation route to CALLER using responders current location and floorplan.
12 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
