This NG9-1-1 Core Services
specification builds upon prior NENA publications including i3 requirements and
architecture documents. The i3 solution supports end-to-end IP connectivity;
gateways are used to accommodate legacy wireline and wireless origination
networks that are non-IP as well as legacy Public Safety Answering Points
(PSAPs) that interconnect to the i3 solution architecture, as described below.
NENA i3 utilizes the concept of an Emergency Services IP network (ESInet),
which is designed as an IP-based inter-network (network of networks) that can
be shared by all public safety agencies that may be involved in any emergency
and a set of core services that process 9-1-1 calls on that
network (NGCS – NG9-1-1 Core Services). The i3 Public Safety Answering
Point (PSAP) is capable of receiving IP-based signaling and media for delivery
of emergency calls conformant to the i3 architecture standard.
document describes how NG9-1-1 works after transition from E9-1-1, including
ongoing interworking requirements for IP-based and TDM-based PSAPs and
origination networks. See the full
document and its Executive Summary for further detail.
