Richard Muscat Roger Hixson, ENP Defining and Updating Classes of Service and Other Identifiers in NG9-1-1 Richard Muscat Roger Hixson, ENP

Historical Class of Service (from NENA Master Glossary) A designation of the type of telephone service, e.g. residential, business, Centrex, coin, PBX, wireless. Ref: NENA 02-010 Ref: NENA 02-011

Historical Class of Service (from Virginia Wireless 9-1-1 Call Processing Terms For The Telecommunicator) A designation of the type of wireless location service. (MOBL, W911, WRLS, WPH1, WPH2)

Historical Class of Service (from Mid-America Regional Council’s Wireless and VoIP Training Manual) Why do some VoIP 9-1-1 calls look like wireline and others like wireless? A. True VoIP calls have a Class of Service or Type code of VOIP. Some companies sell their service as VoIP, but send 9-1-1 calls through the landline network. These calls will have a Class of Service the same as landline.

Historical Wireline (e.g., RES, BUS, etc.) Wireless (e.g., WRLS, WPH2, etc.) VoIP (e.g. VOIP, etc.)

Historical Customer Name Field usage John Smith AT&T Mobility or Verizon Wireless Microcell/Femtocell @Home Hotspot Wi-Fi Callling

Historical Class of Service may be used to provide an indication of: (1) what type of location information the Telecommunicator and/or the 9-1-1 CPE and Mapping should be expecting (e.g., civic location or x, y coordinates)? (2) how the Telecommunicator should handle receipt of the 9-1-1 call and dispatch of the 9-1-1 call (e.g., commercial building type vs. single family residence; dispatching for a hang-up 9-1-1 call with no answer on callback; rebidding for location)? (3) expected accuracy level quality of location information (e.g., WPH1 vs. WPH2), and/or whether the caller is believe to be fixed, mobile, or nomadic (e.g., RES, WPH2, VNOM)

NENA 02-010 Last updated in 2006 to additional VoIP Classes of Service

Next Generation 9-1-1 In NG9-1-1 more detailed information may be available, such as: Service Environment: This element indicates whether a call is from a business or residence. (Required unless the ’Service Type’ value is “wireless”.) Service Type: This defines the type of service over which the call is placed (similar to the Class of Service delivered with legacy emergency calls in some regions). The implied mobility of this service cannot be relied upon Service Mobility: This provides the service provider’s view of the mobility of the caller’s device. As the service provider might not know the characteristics of the actual device or access network used, the value should be treated as advisory and not be relied upon.

NG9-1-1 Data Mapping (Transitional) XXXX

NG9-1-1 Data Mapping (Transitional)

National Emergency Address Database (Discussion Proposal) WDL2 indicates a wireless 9-1-1 call that provides: civic oriented data (address and sub-address location [where appropriate]) in addition to traditional WPH2 geodetic X, Y and Uncertainty data associated with the caller’s location (where available).  When this CoS is used, it indicates the civic oriented data is expected to meet the highest quality level criteria to be “dispatchable”, and indicates that the sub-address location within the building address is very close to the caller’s location.  

National Emergency Address Database (Discussion Proposal) WDL1 indicates a wireless 9-1-1 call that provides: civic oriented data (address and building zone [where appropriate]) in addition to traditional WPH2 geodetic X, Y and Uncertainty data associated with the caller’s location (where available).  When this CoS is used, it indicates the civic oriented data is expected to meet the medium-quality level criteria to be “dispatchable” by building zone but also indicates a less detailed location than WDL2. 

National Emergency Address Database (Discussion Proposal) WCVC indicates a wireless 9-1-1 call that provides: civic oriented data (address) in addition to traditional WPH2 geodetic X, Y and Uncertainty data associated with the caller’s location (where available).  When this CoS is used, it indicates the civic oriented data is not expected to meet the criteria to be “dispatchable” by either building zone (WDL1) or sub- address location (WDL2).

National Emergency Address Database (Discussion Proposal) Location Field Limitation of approximately 20 bytes on average (range may be 12 bytes to 60 bytes)? For NEAD uses, unique location items may be: Flr, Rm, Suite, Zone (floor quadrant) Mezz, Lobby, Bsmt?
