NENA Development Group



The Core Services Committee is focused on 9-1-1 Authority responsibilities related to development and management of systems operations and system administration functions, including data definition and management, business rules, validation (LVF), routing (ECRF, ESRP, PRF), Location services (Legacy ALI, LIS), and any ancillary data services (e.g., wireless, wireline and VoIP data).

This Committee is focused on management and administrative oriented subject matter, and also addresses service contracts (e.g., SLA’s, etc.) that may be technically or operationally focused.

  • Data Structures - Co-Chairs, Jason Horning, ENP and Matt Serra, ENP
    Incorporates MSAG and GIS formats, ALI and PIDF-LO formats, Federal Geographic Data Committee (FGDC) integration, NIEM conformance, alignment with other stakeholder organizations (NIMS, US Fire Administration, NCIC, NTSB), etc.
    • Workgroups
      • XML Schema Development:
        Addresses data formats and protocol technical issues that impact data elements as part of the overall 9-1-1 architecture. This subcommittee has overall responsibility for the Data Technical Standards document 02-010 and all XML schemas.

      • GIS Data Model for NG9-1-1:
        This document defines the Geographic Information Systems (GIS) database model that will be used to support the NENA Next Generation 9-1-1 (NG9-1-1) systems, databases, call routing, call handling, and related processes.

      • NG9-1-1 Additional Data: 
        Charged with identifying the data requirements and data formats to carry Additional Data about a Call, Caller, and Location.  This data is intended to better support call taking, dispatch,  first response, and PSAP administrative functions.

  • NG Data Management - Co-Chairs, Kathy Liljequist and Ira Pyles, ENP
    Develops all implementation and maintenance processes for NG9-1-1 data management.
    • Workgroups
      • NG9-1-1 Data Management
        Currently developing the standards document for Discrepancy, Performance, and Audits for NG9-1-1.  The first draft is covering Discrepancy and Performance Reports.  After the document is published, Version 2 will include the Audit reports.

      • Provisioning and Maintenance of GIS data to ECRF/LVF 
        This Working Group focuses on the data governance and data quality aspect of the NG9-1-1 geospatial data used by the ECRF and LVF.  This encompasses the people, processes and procedures required to create consistent and proper handling of geospatial data provisioned by 9-1-1 authorities and used by ECRF and LVF

      • Site/Structure Address Points (SSAP): 
        Is currently developing a document to serve as a guide for those developing site/structure address point data in a GIS for use in 9-1-1. Site/structure address points must represent addresses assigned by the local addressing authority but identifying when or how a new address needs to be assigned is not the intent or within the scope of the document.

      • Policy Routing Rules (PRR):  

        The PRR WG focuses on the development of rules in a NG9-1-1 system that supports the diversion of calls when the target PSAP is unavailable or unable to take those calls. Version 1 of the standard was approved in August 2013. The PRR WG will now undertake the development of an operations guide for 9-1-1 Authorities. This document will provide background and recommendations on defining Policy Routing Rules for 9-1-1 Authorities at all levels that are involved in NG9-1-1 implementations.The PRR WG will begin work on the operations guide on Friday 11/15/13 at 9:00 am MTN. The WG leaders are encouraging broader participation especially from the 9-1-1 Authorities.
