  2. Wireless E9-1-1 Service in California is governed by: • FCC Order 94-102 requirements on wireless service providers to deliver 9-1-1 calls to the local Public Safety Answering Point (PSAP), if the PSAP requests it • Public Utilities Code (PUC) Section 2892(a) which requires 9-1-1 calls to be delivered at no charge for airtime, access or similar usage charge and without the need for user validation or a service subscription • PUC Section 2892(b) which governs what California agency has the authority to take the wireless 9-1-1 call

  3. All Wireless 9-1-1 calls are routed by carriers to the California Highway Patrol (CHP) unless three things occur, as defined by PUC 2892(b): • the local PSAP agrees to take wireless 9-1-1 calls -- some do not • the call is not from a freeway or highway -- CHP’s authority • the CHP agrees to have the carrier re-route the call to the local PSAP -- some cell sectors overlap highway and local jurisdiction

  4. The Warren-911 Emergency Assistance Act gives primary authority to the California 9-1-1 Emergency Communications Office (9-1-1 Office) for implementation, funding and operational standards governing California’s 9-1-1 system. The 9-1-1 Office plays the key role of coordinating the parties needed to implement wireless 9-1-1 service: • the CHP • local PSAPs • wireless service providers -- who deliver the calls to the wireline 9-1-1 network for delivery to the CHP or PSAP • 9-1-1 Network and Database Managers (AT&T and Verizon) -- who establish the routing keys required to deliver wireless 9-1-1 calls through the wireline system

  5. The 9-1-1 Office Wireless E9-1-1 Project -- Objectives: • Preparing all California public safety answer points (PSAPs) to accommodate the information to be delivered by wireless carriers under Phase I and Phase II of the FCC Order.  • Phase I specifies that the telephone number and receiving cell site or sector of the 9-1-1 caller be delivered to the PSAP.  • Phase II adds a more precise location, (usually with 50-100 meter accuracy or better) in the form of latitude/longitude coordinates, to the Phase I information.  • On September 7, 2007 California became 100 % compliant with deployment of Phase II cell sites in Mariposa and Lassen counties. • A major emphasis of the wireless project is the redistribution of statewide wireless 9-1-1 call volumes from the CHP to local PSAPs

  6. The 9-1-1 Office RED Project -- Routing on Empirical Data • In 2007, 42% of wireless calls received busy signals or failed to get answered • Many of the calls answered by the CHP had to be transferred to local PSAPs with jurisdiction for the call -- causing unnecessary delay to emergency response • The RED project is an analysis of actual caller locations by cell sector, to determine the jurisdiction where the majority of calls originate. • Slide one: Wireless calls from one cell sector in Ventura County • Slide two: CHP and Local PSAP calls identified • The CHP and local PSAP review the historical data of each cell sector to determine whether rerouting from CHP to the local PSAP is needed

  7. Slide one: Wireless 9-1-1 Calls from one cell sector in Ventura County

  8. Slide two: CHP and Local PSAP calls identified

  9. RED Project Accomplishments and Statistics: 2007 – 2010 time period • As of June 30, 2010 38% of cell sectors were accepted for re-routing to local PSAPs -- reducing call transfers and improving response times • As of October 2010, the number of wireless calls receiving a busy signal or failing to be answered dropped from 42% to 5% • The number of successfully processed wireless calls went from 11.6 Million to an expected 14.2 Million • The CHP increased their call taking ability from 3.5 to 6.9 Million • The number of calls processed by Local PSAPs has more than doubled from 3.1 to 6.6 Million • Please refer to the 9-1-1 Office handout on the RED project
