    1. Qwest Wireless E-911 Phase IIDeploymentStatus April 09, 2003 Presented by: Travis Beard Product Manager E-911 and Regulatory Issues

    3. Network Based Solutions

    4. Accuracy Requirements 100 M accuracy 67% of the time. 300 M accuracy 95% of the time.

    5. Pros and Cons Pro’s Works well in urban canyon settings. No handset upgrades needed.

    6. Carriers using Technology Manufacturers of Network Solutions Grayson Wireless True Position Carriers Implementing AT&T Cingular T-Mobile (formerly Voice Stream Nextel (in some markets) Verizon (in some markets) And other medium and small sized carriers.

    7. Handset/Hybrid Solutions

    8. Accuracy Requirements 50 M 67% of the time 150 M 95% of the time Handset sales requirements (medium sized carrier only dates) Begin selling A-GPS handsets by 03/01/03 25% of all new handset sales have A-GPS capability by 05/31/03. 50% of all new handset sales have A-GPS capability by 11/30/03. 100% of all new handset sales have A-GPS capability by 05/31/04. 95% total subscriber penetration of A-GPS handsets by 12/31/05.

    9. Pros and Cons Pro’s Works well in rural and suburban settings. Ability to use network timing for location fixes when GPS satellites can not be used. Privacy controlled at handset (exception for 911). Messaging takes place as part of air interface. Supports mid-call location today! As handset technology advances so will location technology. Easy to implement

    10. Carriers using Technology Sprint PCS Verizon (most markets) Alltel Nextell (Some markets) Cricket Qwest Wireless Most of the CDMA carriers have adopted this solution.

    11. Qwest Integration Trials (Pre-FOA) Qwest conducted a Pre-FOA trial in Colorado Springs CO in early 2002. Purpose of this trial was to: Integrate E3, E5, E12 and E2 interfaces. Validate that all vendors compliant with J-STD-036 (MPC, PDE, MSC, BSC, ALI, PSAP CPE). Validate accuracy performance

    12. Qwest FOA and Accuracy Trials Conducted 2 end to end trials in Colorado Springs, CO (Lucent) and Pottawattamie County, IA (PCSAN). Testing included end to end 911 calls with PSAP. Validated accuracy and live 911 Phase II call scenarios. Both scenarios were focused on rural and suburban settings. Handset accuracy testing Conducted additional accuracy trial in Seattle Washington. Did not include PSAP Testing focused primarily on accuracy in Urban and Dense Urban settings. Included Water and tunnel scenarios. Handset accuracy testing.

    13. Qwest Deployments Currently have deployed Phase II with the following PSAP’s: El Paso/Teller County, CO (2 PSAP’s) City and County of Denver, CO (1 PSAP) Boulder County, CO (3 PSAP’s) Larimer County, CO (2 PSAP’s) King County, Washington (5 PSAP’s) (most of Seattle Metro area) Minneapolis Metro Area (20 + PSAP’s)

    14. Key Learning's from Deployments PSAP should be concerned about CAD and ALI format changes. PSAP must have Rebid functionality programmed within CPE. Audio break up at call set-up and during rebid. Accuracy of Cell site data impacts accuracy of location fixes. Cell site calibration used to enhance network timing and hybrid fixes shortened from 6-8 hours per cell site to 20 minutes. PSAP readiness must be completed before a carrier can deploy.

    15. Qwest Communications 30W ALI Format

    16. Phase II Call Flow

    17. A-GPS Phone examples

    18. Handset Sales Qwest began selling its’ first A-GPS capable handset on 01/31/03. Initial sales of handsets is between 10-20% of all new handset sales with minimal marketing or education to sales force. A-GPS handsets being sold in all markets. Multiple handsets offerings need to be offered to meet 50% and higher benchmarks. On target to achieve all FCC benchmarks regarding handset sales.

    19. Challenges and Issues Accuracy improvements using AFLT and hybrid technology. Routing and providing Phase 2 information at call set-up versus requiring PSAP to “pull” Phase 2 information after the call has been routed. (PDE software release 5.0 should provide this functionality) PSAP’s requesting service from QW must align CPE upgrades within six months of request. If these upgrades do not happen, QW will be in a position to deploy in other areas where the upgrades have been completed delaying deployment. Processes will need to continue to be improved upon to improve efficiencies of resources that are required to enable deployment. Handset sales will need to be monitored on a monthly basis to assure penetration metrics can be achieved. Removal of Latitude and Longitude on a “WPH1” ALI record.
