Towards Providing Enhanced 911 Emergency Service in IP Telephony
Serge Panossiany · 1999
Emergency service is a critical service provided in the public switched telephone network. With the increasing demand to introduce IP Telephony, the issue of providing 911 service in the new environment will arise. In this paper, we address the issue of emergency 911 service in the TCP-UDP/IP network architecture that supports enhanced emergency features. We identify the functionalities needed in this environment. In particular, we outline a Location Resolution Protocol that is needed for the infrastructure; further, we describe various components in the E911-IP environment, and present a conceptual view on how the service can be provided when the Location Resolution Protocol is coupled with other existing and proposed protocols. In addition, we present the call initialization processing steps in the new environment.
