Emergency Communications

Today¿s 911 system is built on an infrastructure of analog technol. that does not support many of the features that should be part of an emerg. response. Efforts to splice newer, digital technol. onto this infrastructure have created points of failure where a call can be dropped or misdirected, sometimes with tragic consequences. This report discusses how modernizing the system to provide service that approaches the expectations of its users will require investments in new technol. that should incorp. Internet Protocol (IP) standards. An IP-enabled emerg. commun. network that supports 911 will facilitate interoperability and system resilience; improve connections between 911 call centers; provide more robust capacity; and offer flexibility in receiving calls.

The need appears increasingly urgent for timely decisions by policy makers on new infrastructure for emergency communications and spectrum allocation for public safety radios.

Preferential Emergency Communications: From Telecommunications to the Internet, a professional monograph, is divided into three sections. The first describes systems and protocols that have been deployed as private networks for use by government agencies like the U.S. Department of Defense. This section also presents an in-depth discussion on MLPP. We then present current work in the area of Land Mobile Radio, commonly used by local emergency personnel such as police and fireman. This second section also describes systems that have been deployed over the public switched telephone network. Finally, the third section presents insights on trying to support emergency communications over TCP/IP networks and the Internet. In this last item we look into what IETF protocols can be considered candidates for change, as well as those protocols and applications that should not be altered.
