3rd Standards Development Organizations (SDO) Emergency Services Workshop


Summoning police, fire department, ambulance or other emergency services in case of emergency is one of the fundamental and most-valued functions of the telephone. As telephone functionality moves from circuit-switched telephony to Internet telephony, its users rightfully expect that this core functionality will continue to work at least as well as is has for the older technology. New devices and services are being made available which could be used to make a request for help which are not traditional telephones, and users are increasingly expecting them to be used to place emergency calls. However, many of the technical advantages of Internet multimedia require re-thinking of the traditional emergency calling architecture. This challenge also offers an opportunity to improve the operation of emergency calling technology, while potentially lowering its cost and complexity.

Existing emergency services rely exclusively on voice and conventional text telephony (known as TTY in the United States) media streams. However, more choices of media offer additional ways to communicate and evaluate the situation as well as to assist callers and call takers to handle emergency calls. For example, instant messaging, wideband speech codecs and video could improve the ability to communicate and evaluate the situation and to provide appropriate instruction prior to arrival of emergency crews. Future emergency services will allow the creation of sessions of any media type, negotiated between the caller and PSAP using existing SIP protocol mechanisms.


Today many standardization activities take place with regard to various parts of the emergency service architecture. They are, however, not as coordinated as they could be. There is the danger that uncoordinated activities lead to solutions that either do not work in some circumstances or to solutions that lead to duplicate work due to lack of knowledge of work done by other SDOs.

Two SDO emergency services workshops have been held already and a number of other smaller coordination activities took place. These two workshops took place in the US (New York and Washington DC) whereas this workshop is hosted in Europe.
