2 OnStar Seeking Priority Access to PSAPs Advancements in technology have enabled OnStar to contract with a third party provider to contact PSAPs via For verified emergency situations (OnStar still receives the initial call) By utilizing VOIP call pathing, While preserving telematics location, and Selective router security Project stages: Stage One : delivery of OnStar Call Center callback number and visual display of Telematics call and OnStar Call Center indicators (2 nd Q 2007) Stage Two : Stage One data plus X,Y coordinates of the calling vehicle using SIP (1 st Q 2008 tentative) Stage Three: Platform for delivery of crash data (TBD) Each PSAP will be contacted prior to implementation and OnStar will only route the call to PSAP trunks with the approval of the PSAP

3 OnStar Background Combine and integrate directly into the vehicle s electrical architecture Cellular technology GPS location capability Sophisticated voice recognition technology Call center-based services Safety, security and peace of mind Routing and point of interest One button hands-free calling Nearly 4.5 million subscriber Multiple languages /TTY Standard most GM vehicles

6 Sample Call Types Contacting the PSAP using the trunk lines will be limited to situations where there is an immediate need for police, fire or EMS: Vehicle crash with injuries or without injuries, if blocking traffic Medical emergency Fire Crimes in progress or just occurred Erratic drivers Potential traffic hazards (i.e., object in or adjacent to the roadway that could cause a collision)

7 Proposed Priority Access to PSAPs via Existing Trunks Benefits to the PSAP: Makes the PSAP job a bit easier Call has been pre-screened, OnStar Advisor verifies emergency nature of call prior to sending to PSAP X&Y coordinates used to determine proper PSAP for call routing Utilizes existing trunks Assures priority classification for emergency calls arriving at the PSAP

8 Back Up Information

9 OnStar s Proposed Call/Data Delivery Model Call Flow: 1. A Telematics device (OnStar) initiates a call to a local cellular tower which is forwarded to the serving Mobile Switching Center (MSC). This causes a wireless call to be sent to the public switched telephone network (PSTN). 2. The call is routed through the MSC to the local End Office (EO) serving the Telematics service provider s (OnStar s) call center (TSP CC). 3. The call received at the TSP CC (OnStar) consists of the location, data from the collision, and the voice call. The attendant at the TSP CC (OnStar Advisor) receives the call and determines emergency help is required. The attendant (OnStar Advisor) queries the local Emergency Routing Database (ERDB) with the location of the caller (lat/long) to determine which public safety answering point (PSAP) should receive this call. The ERDB provides the PSAP info and a 10-digit phone number for that PSAP.

10 OnStar s Proposed Call/Data Delivery Model Call Flow: 4. The attendant (OnStar Advisor) establishes a conference call by dialing the 10-digit number. The call is passed via the PSTN to a Voice over Internet Protocol (VoIP) call server. 5. Based upon the dialed digits, the VoIP call server determines that this is an emergency call and queries the VoIP Positioning Center (VPC) for routing instructions by forwarding the dialed digits. 6. The VPC queries the ERDB to determine the proper PSAP based upon the forwarded digits. 7. The VPC assigns an Emergency Services Query Key (ESQK) designated for that PSAP and stages a record with the ESQK and call back number (CBN) of the Telematics service provider (OnStar). 8. The VPC responds to the routing query with the ESQK, Emergency Services Routing Number (ESRN) and Last Routing Option (LRO). 9. The VoIP call server uses the ESRN to determine the appropriate Emergency Services Gateway (ESGW) and routes the call appropriately.

11 OnStar s Proposed Call/Data Delivery Model Call Flow: 10. The ESGW converts the Session Initiation Protocol (SIP) to Time Division Multiplexing (TDM), uses the ESQK to determine the correct PSAP and routes the call appropriately. 11. The Selective Router delivers the call and the ESQK to the PSAP 12. The PSAP queries the Automatic Location Identification (ALI) database with the ESQK. 13. The ALI steers the query to the correct VPC per the ESQK. The VPC responds to the ALI query with the staged ALI record for that ESQK. 14. The ALI forwards the data to the PSAP. * The proposed design described above is intended to serve as an interim delivery model until such time as NG9-1-1 functionality is fully deployed; it utilizes the standard VoIP elements, including ESRNs and ESQKs, and complies with the NENA i2 standard and the guidelines for E2 Query from the ALI database.
