9-1-1 Core Services

Submit an Issue to the

NENA Development Group



This committee will focus on the 9-1-1 system core functions and interfaces necessary to accurately route and deliver 9-1-1 calls (voice, text, images, sensors, and video) and caller location data to the correct PSAP supporting the geographic location of the caller; and the acquisition by the PSAP, or responders, of additional data and information related to a call, a caller, or the incident being reported.

This committee will identify and define the IP protocols and interfaces necessary to support interoperability between 9-1-1 systems and to support the communications methods and devices currently in common use by the general public that could reasonably be expected to support an emergency request for assistance.

      • i3 Architecture, Co-Chairs Brian Rosen & Steve O'Conor ENP                   This Working Group is responsible for the ongoing development and evolution of the NENA i3 standard for NG9-1-1 that provides call and data handling functionality between 9-1-1 call originators and 9-1-1 call centers (PSAPs), with an emphasis on i3 Emergency Services IP Networks (ESInets)/Next Generation Core Services (NGCS). Major topics being addressed in version 3 of the standard include: (1) Network routing, performance and security; (2) Core, ancillary, and transitional functions; (3) Data definition, including location, GIS, and additional data, including REST/JSON schema definition; (4) Next generation 9-1-1 PSAP multimedia call and data delivery interfaces; and (5) Interfaces to support test calls and testing of Policy Rules. ANSI project initiation notice was published in May 2015 for version 3. Review process initiated in 2Q2018. Calls are Thursdays at 10:30 am to Noon ET.  20161003_ISF i3 v3 (ANS)_CharterApproved 20161025


      • Conveyance of Emergency Incident Data Document (EIDD), Co-Chairs Henry Unger,  Tony Dunsworth & Rick Blackwell ENP    The Conveyance of EIDD Working Group is focusing on the development of an ANSI accredited NENA/APCO Standard for transporting (conveying) Emergency Incident Data Documents (EIDDs) between systems (FEs). The initial definition of the data elements contained in EIDDs is documented in a joint APCO/NENA ANS. The new Standard under development by this NENA/APCO working group will define how EIDDs are exchanged and transported within and between PSAP agencies, as well as with other stakeholders. Expertise in information sharing and specifically in using web services and other protocols is desired. Operational expertise familiar with the needs for exchanging data between call takers and dispatchers, emergency responders and other user systems is also highly sought. Participation and contributions are sought from technical and operational subject matter experts. ANSI project initiation notice was published in May 2015. Calls are Fridays at 2-3 pm ET.  20160201_ISF-EIDD conveyance_20160823 CharterAppvd
