ATIS-0700015的发布，IMS发起和ESInet/传统选择性路由器终止的3GPP通用IMS紧急程序的实施，需要一份补充文件，用简单的语言解释IP到NG9-1-1接口，不过度依赖技术术语和首字母缩写，协助公共安全部门了解新标准对运营的影响。本文件解释了ATIS-0700015标准与当今非互联网协议多媒体子系统（IMS）原始网络中现有网络功能相比的运行影响。它为公共安全部门提供了所需的洞察力，并概述了未来由IMS发起的紧急呼叫的预期内容。 本文件不是规范，但仅供参考。

The publication of the ATIS-0700015, Implementation of 3GPP Common IMS Emergency Procedures for IMS Origination and ESInet/Legacy Selective Router Termination, there is a need for a supplemental document that explains, in plain language, the IP to NG9-1-1 interfaces, without overdependence on technical terms and acronyms, to assist Public Safety in understanding the operational impact of the new standard. This document explains the operational impacts of the ATIS-0700015 standard compared to existing network functionality in today's non-Internet Protocol Multimedia Subsystem (IMS) originating networks. It provides Public Safety the needed insight and overview of what to expect from future IMS originated emergency calls. This document is not a specification but is intended to be informative only.
