The NENA i3 Standard for Next Generation 9-1-1 provides detailed functional and interface specifications for Next-Generation 9-1-1 (NG9-1-1) and serves as the foundation for NENA?s suite of NG9-1-1 standards. As this is a 2nd public review, only
the highlighted edits are open for comment.
Version 3 includes key updates to NG9-1-1 infrastructure to ensure continued support for interoperability on a national and international scale. Version 3 changes include a move to a REST/JSON architecture for data interactions between functional elements
and systems, improvements to security, major updates to the call bridging (Bridging Service), Discrepancy Reports, an Outgoing Call Interface Function, blind transfer support, updates to novel call types (including non-interactive calls and Advanced
Automatic Crash Notifications [AACNs]), and more. Version 3 also incorporates a number of new IETF specifications and has made adjustments to addressing to harmonize schemes across Europe and North America.
i3 is an open standard developed with the contribution of a large community of industry, academic, and public-safety experts. NENA?s development process is always open to all.
