Today’s 9-1-1 & Wireless

1. Today’s 9-1-1 & Wireless 9-1-1 Advisory Council 9-1-1 Program office Rhonda Sullivan rsullivan@mt.gov

3. Wireless 9-1-1: Phase 0 Wireless call delivered to a PSAP with voice only.

4. Wireless E9-1-1: Phase I The FCC requires the wireless carriers to deliver the telephone number and the location of the cell site/sector.

5. Wireless E9-1-1: Phase II PSAPs will receive both the wireless phone number and the caller location information. The call is routed based on cell site/sector or on caller location information. 

6. Wireless Class of Service (COS): • MOBL = indicates a call that is neither Phase I nor II but Basic. • WRLS = indicates that Phase I location data is being provided from a Phase I cell site. • WPH1 = indicates that Phase I location data is being provided from a Phase II site. • WPH2 = indicates that Phase II location data is being provided from a Phase II tower.

7. 9-1-1 Statistics The United States currently has 6,149 primary and secondary PSAPs in 3,135 counties. Of which: • 97.1% of 6,149 PSAPs have some Phase I • 95.0% of 6,149 PSAPs have some Phase II • 92.9% of 3,135 Counties have some Phase I • 90.0% of 3,135 Counties have some Phase II • 97.9% of Population have some Phase I • 97.0% of Population have some Phase II

8. Phase II - RE-BID/Location Updates: • Call queries the Mobile Positioning Center (MPC), the Position Determining Equipment (PDE) is allowed up to 30 seconds to provide a valid Phase II location. • The PDE may not have responded with final Phase II location information to the MPC by the time the call is answered by the PSAP and initial ALI query to the MPC is performed. • The PSAP may have to perform a re-bid to receive the caller’s updated location information. Calls are generally routed in 5 seconds or less. Once routed it takes about 1 second for the ALI bid to be made.

9. REBID Continued: • If accurate latitude & longitude cannot be calculated in 6 or less seconds the wireless carrier will deliver Phase I location data. • The PSAP will then need to re-bid the ALI approximately 15 to 30 seconds after they receive the initial ALI bid to obtain the 9-1-1 caller’s accurate latitude and longitude. *DO NOT HIT THE RE-BID BUTTON MULTIPLE TIMES* wait 20 seconds in between re-bids. • Best practice is to allow PSAPs to make manual mid-call location updates.

10. Wireless Phase 2 Information: • When the wireless call originally comes in – it will almost always appear as a Phase I call initially. The way to determine if the call is Phase I is to look at the “COS” – on the upper right corner of the call information screen. If the display reads “WRLS” – this is a Phase I wireless call. • To get the Phase II information- the wireless database must be “rebid”. To rebid – touch the button above the call information screen which reads “REQUEST ALI”. DO NOT HIT THE REBID BUTTON MULTIPLE TIMES – wait 20 seconds in between re-bids. This sends a request to the wireless database (it will take a few seconds). If Phase II information can be determined, the “COS” will now change to “WPH2”. Example of what your screen might show: • Tel#: 406-471-3421 COS: WPH2 (class of service) • Date: 04/26/06 Time: 1335 • Name: Verizon Wireless • Address: 55 • Strt: 3rd Ave West North – NE Sector • Loc: Call Bk= 406-253-8794 0151 (ESN) • Stmt: City Kalispell • Sup1: Tel = VZW • Info: +048.19966 -114.31843 (lat & long) • Sup2: • Law: WIRELESS • Fire: WIRELESS • EMS: WIRELESS • EMS2: • INFO1: • INFO2: • INFO 3: • INFO 4:

11. Wireless Phase II Information – Field Entries: • Tel # field is a routing key for the wireless company and not a useful field for the PSAP – disregard – unless this information has been requested by the wireless carrier for troubleshooting purposes. • COS: Class of Service – will display WRLS (Phase I) or WPH2 (Phase II) • Date: Displays the date the call arrived at the PSAP • Time: Displays the time the call arrived at the PSAP • Name: Displays the Name of the wireless carrier • Address: Displays the numerical street location of the cellular tower from where the call originated. • Strt: Displays the street address of the cellular tower from where the call originated (May also display the tower sector) • Loc: Displays the call back number of the cellular phone which placed the call, also displays the ESN (Emergency Service Number) • Stmt: Displays the community in which the cellular tower is located. • Sup1: This field is not used by the wireless carriers. • Tel=: The three digit code of the wireless carrier • Info: Displays Latitude and Longitude of the tower if the call is Phase I or of the actual caller if the call is Phase II. • Sup2: This field is not used by the wireless carriers. • Law: The field will always display “Wireless” on a wireless call. • Fire: The field will always display “Wireless” on a wireless call. • EMS &2: The field will always display “Wireless” on a wireless call. • INFO1,2 &3: This field is not used by the wireless carriers.

12. Wireless - Troubleshooting: Examples of issues and the possible solutions: Issue: PSAP is getting 9-1-1 calls routed to them from cell sites outside of their jurisdiction or getting misrouted 911 calls. Possible Solution: The PSAP should contact the wireless carrier or the carrier’s third party service provider. Depending on the carrier, the contact could be in the wireless carrier’s NOCC (Network Operations Control Center), or someone in an E911 implementation group. The contact may vary depending on if the PSAP is getting basic 911 or enhanced 911. Issue: PSAP is getting 9-1-1 calls with no information and the PSAP has implemented wireless E9-1-1 Phase I or II. Possible Solution: The PSAP should contact the wireless carrier because it is likely that a new cell site has been turned up without going through the Phase II implementation process. Depending on the carrier, the contact could be in their NOCC, the carrier’s third party service provider, or someone in an E911 implementation group.

13. Troubleshooting Continued: Issue: PSAP receives 911-000-0000. Possible Solution: This is a wireless ANI failure. Possibly the carrier could not identify the cell phone and therefore could not send ANI through the network. If constant problem track calls and report to 911 service provider if happening on multiple carriers. If problem occurs on a specific wireless network contact that provider with examples of failures Issue: PSAP is not able to re-bid a 911 call. Possible Solution: The phone may not be capable of delivering location, phone user may have disabled this capability, phone may be calling from a “fringe area”. Issue: PSAP’s ALI connection is down or sporadic. Possible Solution: The PSAP’s 911 service provider is the likely contact. The service provider would then work back with any third party database providers, if necessary. Issue: PSAP is getting no caller/location data or only partial caller/location data. Possible Solution: The 911 service provider is the likely contact. The 911 service provider would then work back with the third party service provider, if necessary.
