CA Wireless E9-1-1 Objective

• To implement and maintain the capability to
  deliver wireless emergency phone calls to the
  appropriate PSAP with caller identification
  and location information.

Wireless Caller Background

• Cellular Subscribers grew from 16 million in 1994
  to 207.9 million in 2006.
• 69 of US population use cell phones.
• 6 of US households are wireless only.
• In CA in 2005, of the 20 million 9-1-1calls, more
  than half were wireless.
• CTIA Wireless Quick Facts April 2006.

Wireless E9-1-1 Call Path
1. Wireless caller makes 9-1-1 call 2.
Call hits a cell tower and is routed to PSAP
based upon the sector coverage 3. WSP
Mobile Switching Centers connected to S/Rs and
sends call to PSAP 4. PSAP equipment
uses10-digit pANI to query back to 3rd Party DB
Provider to obtain ANI and ALI for Call Taker
5. Query goes through redundant gateways,
redundant Mobile Positioning Centers, and
redundant Positioning Determining Equipment to
return the Wireless ALI information.

CA W E9-1-1 PSAP Readiness

• CPE - Phase II Compatibility
• Accommodate W-ALI Display (Format 04)
• 10/20 Digit Capable ANI
• Ability to Re-Bid ALI for Phase II Location
  Updates
• CAD Interface
• Will CAD accommodate new W-ALI Format?
• GIS
• Not required to be considered ready.
• PSAP must submit GIS Plan to obtain funding.

• Primary PSAPs 413 (389 local 24 CHP)
• PSAPs deployed 181 (end of Dec. 2006)
• PSAPs not participating 59
• PSAPs with Format 04 not participating 35
• PSAPs needing Format 04 62
• Cell Sectors Cut Over 54,867 of 68K statewide

CA Wireless E9-1-1 Costs
January 2002 to December 2006

• Network 5.3 M
• ALI ckts, T/T trunks, S/Rs, per calls, 10-digit
  non-published lines
• PSAPs 12.4 M
• PSAP 04/Multi-steering, CPE patches, GIS (224 of
  1955 positions)
• WSPs 7.7 M
• 1.00/per sub one-time, 0.05/per sub monthly
• Wireless Coordinators 0.56 M
• Wireless duties and meetings

17
CA Wireless E9-1-1 Deployment Barriers

• PSAPs not willing to take Wireless calls directly
• (all calls will go to CHP if they are not
  routed directly to local primary PSAPs)
• PSAPs arranging to upgrade CPE with Format 04
• Misconception of major call overload and staffing
• Network not in Lassen, Modoc, and Del Norte

18
CA Wireless E9-1-1 Issues

• W-ALI delivery does not have a quality standard
  (several NRF and No ALI Records)
• WSP accuracy is still questionable
• GIS Funding for PSAPs needs to be requested
• W-ALI change for In-building sites shown as
  W911 class of service
• WSPs need to resolve post deployment issues
• Phantom calls continue (calls with no audio for
  both subscribed and non-initialized phones)

19
CA Wireless E9-1-1 Reality

• New State Call Routing Law (1/06) for Local
  agencies to take more sectors for direct routin
• CHP will still take a majority of wireless calls
  (70)
• PSAPs will have some calls on 10-digit emer lines
• More cell sectors coming on line (maintenance)
• County Coordinators taking on wireless
  maintenance

20
CA Wireless E9-1-1 Current Goals

• Have all primary PSAPs agree to take calls
  (sending in a Letter of Agency template on web
  site)
• Have all primary and secondary PSAPs with Format
  04 to display the full ALI display with
  Lat/Lon/Meters/Percent
• Have all PSAPs use 10-digit emergency
  non-published numbers for transfers outside
  network (calls already answered)
• Reduce CHP busies with additional trunking when
  ready
• Complete Lassen/Modoc Network
• WSPs to resolve phantom calls
