Organization: ATIS
Publication Date: 1 August 2018
Status: active
Page Count: 70
scope:

The scope of this Standard is to specify the inter-Emergency Services Network interactions for initial emergency calls that are required to be routed to another Emergency Service Network and calls that may be transferred (bridged) between Emergency Services Networks. This Standard is incremental to ATIS-0500032 in that it focuses on the interactions between those networks. This Standard defines the Stage 2 (architecture) and Stage 3 (protocol) specifications to support the interconnection between Emergency Services Networks.

Purpose

IMS standards for Emergency Services have been under development and enhancement in 3GPP since 3GPP Release 9. However, from a Next Generation Emergency Services (NG9-1-1) network perspective, the IMS architecture only defined Emergency Service call processing for the originating network and has not specified the application of IMS architecture concepts to NG9-1-1 Emergency Services Networks or the interconnection of IMSbased NG9-1-1 Emergency Services Networks with legacy and other Next Generation NG9-1-1 Emergency Services Networks.

The purpose of this Standard is to define the Stage 2 (architecture) and Stage 3 (protocols) to enable the interconnection of North American IMS-based NG9-1-1 emergency services networks with other legacy and Next Generation Emergency Services Networks deployed in North America to support the delivery of initial and transferred emergency calls.

Application

This standard applies to initial requests for emergency services and transfers that require interactions between an IMS-based Next Generation Emergency Services Network and legacy and other Next Generation Emergency Services Networks. This standard applies to routing voice, text, and multimedia requests.
