9-1-1 Public Safety Answering Point Requirements, NENA/APCO-REQ-001.1-2015, introduces
requirements for a NG9-1-1 PSAP that is capable
of receiving IP-based signaling and media for delivery of emergency calls
conformant to the latest version of the NENA i3 Architecture document. An
emergency call enters the i3 PSAP using Session Initiation Protocol signaling.
NG9-1-1 encourages the creation of many new coordination and information access
services to enrich collaborative interactions between all agencies involved in
processing emergency service requests. This document is issued as NENA/APCO
recommended requirements for functions and interfaces between an i3 PSAP and
NG9-1-1 Core Services, and among Functional Elements associated with the i3
PSAP. This document is primarily intended to drive the development of
more standards that meet the technical requirements specified in the document.
