摘要

今天，世界正在经历从传统的PSTN到基于全ip的互联网电话的巨大转变，这意味着PSTN迟早会被VoIP取代。互联网电话用户期望在紧急情况下能够主动请求帮助。问题出现在向紧急服务发起呼叫时，VoIP设备移动而标识符保持不变，无法提供呼叫者的位置。因此，不幸的是，现有的支持紧急呼叫的机制已经在PSTN中发展，不适合处理不断发展的基于ip的电话服务。本文提出了利用传统的E911网络解决基于sip的VoIP系统的E911呼叫问题的机制。

SIP based VoIP System for E911 Service

Today the world is undergoing a massive shift from the traditional PSTN to All-IP-based Internet telephony, implying an eventual replacement of the PSTN with VoIP sooner or later. Internet telephony users have an expectation to be able to initiate a request for help in case of an emergency. The problem arises for originating calls made to emergency services, where VoIP devices move while identifiers remain the same and the caller's location cannot be provided. So, unfortunately the existing mechanisms to support emergency calls that have evolved within the PSTN, are not appropriate to handle evolving IP-based telephony service. In this paper, we suggest the mechanisms that solve the problem of E911 calling on SIP-based VoIP system using traditional E911 network.
