ESIF

Mission

ESIF is an open technical/operational forum to identify and resolve interconnection issues through the voluntary participation of interested parties. The interest of all members will be served by observing the principles of openness, fairness, consensus, and due process.

ESIF develops standards and other documentation for the interconnection of emergency services networks. ESIF will liaise with industry, governmental, standards, and public safety organizations to apprise them of its deliberations and decision, and ensure the proper coordination of activities. Discussion will be focused on the application of current and emerging technologies to maintain and support the interconnection of emergency services networks.


In September 2015, the 9-1-1 Location Technologies Test Bed, LLC announced the selection of ATIS to serve as the Program Manager for the 9-1-1 location accuracy test bed.

ESIF Emergency Services & Methodologies (ESM) Subcommittee is currently developing solutions for:

  • Determination of Test Bed Location(s) and Blending Methodologies for Assessing Accuracy Compliance.
    Addressing the establishment of a test bed that is representative of indoor and outdoor environments and captures certain performance attributes including: location accuracy, latency, and reliability. The standard will address geographic locations that will comprise the test bed, the geographic regions where live 911 calls will be monitored, how different morphologies and regions will be combined into a comprehensive accuracy performance metric, and will identify potential methodology differences between testing for compliance and technology evaluation.
  • Positioning Method Source Codes for Current and Emerging Location Technologies,
    Identifying and requesting positioning method source codes for current and emerging location technologies including likely hybrid combinations.
  • Considerations and Methodologies for Crowd-Sourced and Dispatchable Location Technologies.
    Addressing the unique considerations and methodologies to be applied to testing crowd-sourced (Wi-Fi and Bluetooth) location technologies and to testing dispatchable location methods, as well as determining veracity of the location.
  • Vertical Axis Measurement Test Methodology
    Assessing barometric, Wi-Fi, and other possible vertical axis determination solutions with emphasis placed on calculated solutions.

ESIF Joint Standards Development

The ESIF Next Generation Emergency Services (NGES) Subcommittee is the lead for the IMS911 joint work effort, which addresses the next phase of defining the processing, transport, and/or delivery of Emergency Service calls within the NG9-1-1 network to the appropriate PSAP (ESIF Issue 81). This initiative is a joint effort with the Packet Technologies and Systems Committee (PTSC) and the Wireless Technologies and Systems Committee Systems and Network Subcommittee (WTSC SN). Issue 81 is a continuation of work previously completed by the ESIF NGES for defining the call processing, transport, and delivery of Emergency Service calls within the NG9-1-1 network (ESIF Issue 74).

Wireless E9-1-1 Phase II Readiness Package©

The Wireless E9-1-1 Phase II Readiness Package is one of ESIF's primary work products. Developed to supply PSAPs with a standard method for verifying readiness and providing carriers with complete information to speed implementation, the PSAP Readiness Checklist is part of a three-part package that also includes an introductory letter and instructions document and an Appendix.

NENA

ESIF works closely with the National Emergency Number Association (NENA), which serves the public safety community by focusing on 9-1-1 policy, technology, operations, and education issues. A summary of the ESIF-NENA relationship can be found at ESIF-NENA Relationship and two diagrams depicting the relationship can be found at ESIF-NENA Relationship Diagrams.
