scope:

There are numerous industry standards, technical reports, and requirements documents addressing various aspects for Emergency Telecommunications Service (ETS) support in Next Generation Networks (NGNs). For an end-to-end National Security/Emergency Preparedness (NS/EP) priority communication session in an NGN, priority mechanisms need to be supported over various interfaces and protocols and priority processing needs to be supported within functional elements spanning across various network domains (e.g., wireless access, fixed access, and core network segments), across network boundaries, and within Internet Protocol (IP) transport networks. The deployment of NS/EP priority services (e.g., voice) requires applicability of the particular standard specification in context to the specific interface and protocol, functional element, network domains (e.g., wireless access, fixed access, and core network segments), for the support of NS/EP priority communications in the endto- end NGN infrastructure.

This Technical Report (TR) provides a roadmap view of the subtending suite of ATIS standards, technical reports, and requirements documents showing the applicability of particular standard specifications in the context of enabling deployment of the needed NS/EP priority related functions and capabilities supporting end-to-end priority communications in NGNs. The ATIS set of standards includes national specific applications of 3rd Generation Partnership Project (3GPP), Internet Engineering Task Force (IETF), and International Telecommunications Union - Telecommunications (ITU-T) specifications for the support of ETS. For example, the ATIS standards further define the national specific aspects of the 3GPP protocols and capabilities supporting ETS. This TR includes a roadmap of the dependent 3GPP, IETF, and ITU-T specifications and standards.

Purpose

The purpose of this TR is to consolidate various ETS related specifications and provide a roadmap view to enable ETS deployment in NGNs. The objective is to provide a roadmap view showing the applicability of particular specifications to specific network layer, network procedure, interfaces or network element functional capabilities, and segments making up the end-to-end NGN infrastructure.
