Priority Services for Supporting Emergency Telecommunications in Internet Protocol-Based Networks

This paper briefly reviews the Emergency Telecommunications Services (ETS) requirements and identifies, at a high level, potential areas of impact by the next generation ETS requirements on the Internet Protocol networks. The current Internet Engineering Task Force activities in support of ETS are summarized. Specifically, the support for real-time interactive services is summarized in the following key areas: call control, signaling and quality of service, security support, and priority treatment. The paper concludes with a discussion of the remaining key issues that need to be addressed in support of ETS.
