Summary of Understanding 9-1-1 Call Routing

Main Ideas and Concepts

• Integration of GIS Data in 9-1-1 Systems

  Geographic Information Systems (GIS) data is increasingly vital for 9-1-1 services, specifically in Next Generation 9-1-1 (NG911) systems. GIS Data is used for validating addresses and geospatially routing emergency calls.

• Call Routing and Location Validation

  The call routing and location validation process relies on a geospatial database that includes essential data layers such as:

  • Road center lines
  • Emergency service boundaries
  • Site structure address points
• Quality Assurance Checks

  Before provisioning data to the Emergency Call Routing Function (ECRF) and Location Validation Function (LVF), quality assurance checks (QAQC) are performed to ensure data accuracy and completeness.

• Address Validation Process

  A step-by-step process is described for validating a phone number and address before a 9-1-1 call can be placed. This includes:

  • Checking the address against the LVF
  • Formatting the address into a specific protocol (PITAFLO)
  • Confirming the address validity with the LVF
• Emergency Call Handling

  The video illustrates how calls from legacy systems are converted to modern formats (SIP) for routing. Calls are checked for authenticity to prevent malicious activities before being routed to the appropriate Public Safety Answering Point (PSAP).

• Collaboration and Technology

  The importance of collaboration among various systems and technologies in ensuring effective emergency response is emphasized. The use of modern technology and geovalidation is portrayed as essential for saving lives and property during emergencies.

Methodology/Instructions

• Data Preparation
  • Ensure GIS Data includes:
  • Road center lines
  • Emergency service boundaries
  • Site structure address points
  • Achieve a match rate of at least 98% for GIS Data validation.
• Quality Assurance Checks
  • Run QAQC checks on GIS Data before provisioning to ECRF and LVF.
  • Include necessary fields such as route URI and service URN in the emergency service boundary file.
• Address Validation
  • Convert the address into PITAFLO format for communication with LVF.
  • Query the LVF to validate the address.
• Call Routing Process
  • Convert legacy calls to SIP format.
  • Check for malicious activity before routing the call.
  • Consult the ECRF to determine the appropriate PSAP based on GIS Data.

Speakers/Sources Featured

• Nina: A GIS Data specialist.
• Lis: A colleague assisting with phone registration.
• LVF (Location Validation Function): A system entity that validates addresses.
• ECRF (Emergency Call Routing Function): A system entity that routes calls.
• ESRP (Emergency Service Routing Proxy): A system entity that facilitates call routing.
• Calling Device: Represents the caller attempting to reach 9-1-1.

Overall, the video emphasizes the integration of advanced technology and GIS Data in modern emergency response systems, highlighting its significance in improving the efficiency and effectiveness of 9-1-1 services.
